HESI Fundamentals - Set 4 - Part 2

Correct Answer: Two nurses verify patient and blood

Two licensed staff verify the patient identifiers, blood unit details, and order at the bedside. The double check is required because a wrong-blood-product event can cause fatal hemolytic transfusion reaction in the recipient. Option a is incorrect because Single-nurse identification does not meet the standard for blood product administration. The risk of fatal reaction makes a two-person check mandatory, and skipping the second verification has caused many serious adverse events. Option b is incorrect because Skipping identification when the unit is labeled assumes the labeling is correct without verification. Errors in labeling and dispensing have occurred, and the nurse must verify identity at the bedside every time. Option c is incorrect because Matching only the room number is dangerous because patients change rooms or share rooms. The standard requires multiple identifiers tied to the patient, not the location, before any blood is hung at the bedside.

Correct Answer: Stop transfusion and run normal saline

Acute hemolytic transfusion reaction requires immediate stopping of the unit and starting normal saline through new tubing to maintain access. The nurse notifies the provider and blood bank, and follows facility protocol for documentation and follow-up. Option a is incorrect because Slowing the infusion does not stop ongoing hemolysis. The reaction needs immediate halt of the offending blood product and aggressive support, including fluids and possibly diuretics to protect renal function quickly. Option c is incorrect because Increasing the rate worsens the reaction by infusing more incompatible blood. The intervention compounds harm rather than reducing it and contradicts the principles of managing acute transfusion reactions appropriately under any circumstance. Option d is incorrect because Documenting and continuing the transfusion endangers the patient. The reaction described is potentially fatal and requires emergency interruption rather than charting, since hemolysis continues f

Correct Answer: Up to four hours per unit

Each unit of packed red blood cells should infuse within four hours of leaving controlled storage. The limit reduces bacterial growth risk in a warm hanging unit and is enforced by institutional and national standards. Option a is incorrect because Twelve hours exceeds the safe window and risks bacterial contamination. The unit warms during hanging, and prolonged time outside cold storage allows organisms to grow rapidly within the infusion bag. Option b is incorrect because There is a clear upper time limit on transfusion to ensure safety. Treating the time as unlimited risks bacterial overgrowth and is contrary to institutional and national blood transfusion guidelines used today. Option d is incorrect because Twenty-four hours per unit far exceeds safe limits and creates major contamination risk. The four-hour rule is enforced precisely to prevent the dangers that would arise during prolonged hanging at room temperature.

Correct Answer: Run slowly first fifteen minutes, stay close

The unit runs slowly during the first fifteen minutes while the nurse remains nearby. Vital signs are checked at start, fifteen minutes, and at completion, with the rate increased after the early period if no reaction occurs. Option b is incorrect because Maximum rate from the start risks missing early reactions and overwhelming the patient if a reaction begins. The slow initial rate is a safety measure that allows the team to detect and stop a reaction quickly. Option c is incorrect because Leaving the room and checking after an hour misses the most important early reaction window. The first fifteen minutes are when severe reactions typically appear, and the nurse must remain available throughout that time. Option d is incorrect because Running slowly for four hours could allow the nurse to monitor closely but may not finish within the safe time limit. The rate is increased after the first fifteen minutes once safety has been established.

Correct Answer: Slow or stop, raise head, oxygen

Transfusion-associated circulatory overload presents with dyspnea, crackles, and rising blood pressure. The nurse slows or stops the infusion, elevates the head of the bed, applies oxygen, and notifies the provider for diuretic and further orders. Option a is incorrect because Increasing the rate worsens fluid overload and increases pulmonary congestion. The intervention contradicts the basic principles of managing volume excess and would harm the patient by adding more fluid burden quickly. Option b is incorrect because Continuing the transfusion at the usual rate ignores the developing complication. The patient is showing signs of overload, and continuing the infusion delivers more volume that the cardiovascular system cannot handle safely. Option c is incorrect because Encouraging extra oral fluids worsens fluid overload by adding more volume. The patient already has too much circulating fluid, so adding more contradicts the priority of reducing volume and supporting breathing.

Correct Answer: Right patient, drug, dose, route, time

The classic five rights are right patient, drug, dose, route, and time. Some institutions add documentation, reason, response, education, and refusal as expanded rights to cover additional safety dimensions during medication administration. Option a is incorrect because Right room number is not part of the rights, since rooms can change and identifying by room is unsafe. The patient identification uses two specific identifiers tied to the person rather than location. Option b is incorrect because Right age and gender are demographics that do not appear on the standard rights list. The classic five rights focus on patient identification, drug specifics, and timing rather than demographic categories applied broadly. Option d is incorrect because Right diagnosis is not part of the standard rights, although right indication is sometimes added. The classic five rights focus on patient, drug, dose, route, and time as the foundation of safe administration.

Correct Answer: Pulling, preparing, and at bedside

Three checks occur when the medication is pulled from storage, when prepared, and at the bedside before administration. Each check verifies drug, dose, route, and patient identifiers to catch errors during the medication cycle. Option b is incorrect because Performing checks after administration cannot prevent errors that have already happened. The three-check process is preventive, with each check positioned at a specific point in the workflow before the medication reaches the patient. Option c is incorrect because All three checks after administration also fail to prevent errors. The whole purpose of the system is upstream verification before any medication is given, so retrospective checking does not provide the safety benefit. Option d is incorrect because Three checks apply to all medications, not only narcotics. Limiting the practice to narcotics misses error opportunities for other drugs, including high-alert medications and medications with similar names or doses.

Correct Answer: Catches wrong patient or drug at bedside

Bar-code administration catches wrong-patient and wrong-drug errors at the point of care. The technology serves as a final electronic verification layered on top of the nurse's manual checks and clinical judgment about each dose. Option a is incorrect because Bar-code administration adds to rather than replaces the rights of medication administration. The nurse continues to verify drug, dose, route, and time using clinical judgment, with the scanner serving as a backup safety net. Option c is incorrect because Two-identifier verification remains required even with bar-code administration. The wristband provides one identifier, and the nurse confirms a second identifier verbally before each medication is given to the patient. Option d is incorrect because Bar-code administration does not remove the need for nurse judgment. The nurse must still assess the patient, evaluate the indication, recognize unusual findings, and decide whether the medication is safe at the moment.

Correct Answer: Read back the order to provider verbatim

Reading the order back verbatim allows the provider to confirm or correct the name, dose, and route. The structured read-back is a verbal version of independent verification and prevents many telephone-order medication errors during practice. Option a is incorrect because Hanging up quickly skips the verification step that protects the patient. Without read-back, mishearing a sound-alike drug name or wrong dose can become a serious medication error before anyone catches the mistake. Option b is incorrect because Signing the order without verification eliminates the safety check entirely. Verbal orders carry higher risk for sound-alike confusion, so additional verification through read-back is required by most facility policies and standards. Option c is incorrect because Asking another nurse to repeat the order to the provider does not include the receiving nurse who will carry it out. The nurse who heard the order must read it back personally to confirm understanding.

Correct Answer: Verify with patient and contact provider

The nurse verifies the allergy with the patient, including the reaction type, and then contacts the provider to discuss whether the medication is safe. The clarification protects the patient and updates the chart for future reference. Option a is incorrect because Skipping the medication without checking could leave a needed dose unadministered. The patient may have only had a mild rash, and the medication may still be safe, so verification is preferred over abandonment. Option b is incorrect because Giving the dose anyway without verification ignores a serious safety alert. The patient could have anaphylaxis to the medication, and the nurse must clarify rather than proceeding into a possible adverse event. Option d is incorrect because Contacting pharmacy to remove the alert is inappropriate without first verifying the allergy. The alert protects the patient, and removing it without clarification creates risk for future medication encounters at the institution.

Correct Answer: Two nurses verify separately without prompting

Independent double-check means two nurses verify the medication separately, calculating doses and reading orders without prompting each other. The independence is the key safety feature, since a confirmation bias defeats the purpose of the check. Option b is incorrect because One nurse alone performs a single check, not an independent double-check. The whole point of the practice is two minds working separately, so a single check does not provide the same error reduction at all. Option c is incorrect because Two nurses agreeing without verifying each step is not a true independent check. Confirmation bias and time pressure produce errors when one nurse simply nods along without performing the calculation and verification themselves. Option d is incorrect because Verification done after the dose is given cannot prevent errors that have already happened. The whole purpose of the double-check is upstream prevention rather than after-the-fact catch of an event already harmful.

Correct Answer: Calculate safe range, compare to order

The nurse calculates the safe dose range using the child's weight and compares the result to the ordered dose. Discrepancies trigger clarification with the provider before administration, which prevents tenfold and other major dosing errors. Option a is incorrect because Skipping checks for pediatric patients is the opposite of best practice. Children are at higher risk for harm from medication errors because of small body size, so additional verification is required, not less. Option b is incorrect because Trusting the order without independent calculation eliminates the safety net. Even verified orders can contain errors, and the nurse remains responsible for confirming the dose is appropriate for the patient at administration. Option c is incorrect because Using adult doses on small children is a common dangerous error. Pediatric doses are weight-based, and adult doses can cause overdose and serious harm; the practice is contraindicated in any patient under any condition.

Correct Answer: It highlights differences in similar names

Tall man lettering capitalizes the parts of similar drug names that differ, drawing the eye to the distinguishing letters. The practice reduces wrong-medication errors during preparation, especially with look-alike sound-alike drug pairs in pharmacy. Option a is incorrect because Mixed capitalization is purposeful, not decorative. The format exists to draw attention to specific letters that differ between confusable medications, supporting safer recognition during preparation and administration steps in clinical care. Option b is incorrect because Tall man lettering supplements rather than replaces the standard checks. Nurses still perform the rights, three checks, and any required double-check, with tall man lettering as one additional visual aid during the workflow. Option d is incorrect because Two-identifier verification remains required regardless of label format. Tall man lettering helps with drug name confusion, but it does not address patient identification, which is a separate

Correct Answer: Do not crush extended-release or coated

Extended-release and enteric-coated medications must not be crushed because crushing destroys the timed-release mechanism or the protective coating. Crushing such formulations can cause overdose, irritation, or destruction of the active ingredient by stomach acid. Option b is incorrect because Crushing all solid medications without restriction is unsafe. Many formulations have specific delivery designs that crushing destroys, leading to dose dumping or loss of efficacy and potential harm to the patient. Option c is incorrect because Splitting tablets requires verification that the tablet is scored and approved for splitting. Some tablets are not safe to split because they cannot be divided evenly, leading to inaccurate doses and inconsistent therapy results. Option d is incorrect because Capsule contents are not always safe to mix. Some capsule contents lose stability or efficacy when removed, so the nurse checks the medication reference before opening any capsule for administration th

Correct Answer: Errors carry high risk of serious harm

High-alert medications include insulin, anticoagulants, opioids, intravenous potassium, and chemotherapy among others. Errors with these classes are more likely to cause serious harm, so additional safety steps and double-checks are routine for them. Option a is incorrect because High-alert medications have high harm potential, not low. The label exists precisely because errors with these medications cause severe outcomes more often than errors with the average medication used during care. Option c is incorrect because Errors with high-alert medications are typically not minor. The classification reflects the potential for major adverse events and is the reason additional safety practices and double-checks accompany this group of medications. Option d is incorrect because High-alert medications can absolutely cause adverse events when used in error. The whole reason for the classification is the high-stakes consequence of mistakes, which is why specific extra safety steps are required.

Correct Answer: Place under tongue and let dissolve

The sublingual tablet is placed under the tongue and allowed to dissolve without chewing or swallowing. The mucosa absorbs the medication quickly, and swallowing reduces the rapid effect that the route provides for emergencies. Option a is incorrect because Chewing the tablet defeats the sublingual route by breaking the formulation. The medication must dissolve in saliva under the tongue rather than be ground into pieces that the patient swallows down to the stomach. Option b is incorrect because Drinking water washes the medication down and reduces sublingual absorption. The patient should let the tablet dissolve without water, and any drink interferes with the rapid effect intended by this delivery route. Option c is incorrect because Placing between cheek and gum describes the buccal route, not the sublingual route. The two routes are distinct, and using the wrong placement may slow or alter absorption from the prescribed delivery method.

Correct Answer: Pull skin laterally, inject, release after

Z-track technique pulls the skin laterally before injection, holds during injection, and releases after needle withdrawal. The skin returns to position and creates a zig-zag path that traps the medication inside the muscle. Option a is incorrect because Pulling the skin tight and injecting quickly does not create the Z-track displacement. The skin must move laterally, not just be tightened, and the release happens after the needle has been withdrawn from the tissue. Option b is incorrect because Injecting into subcutaneous fat misses the muscle and is not Z-track technique. The medication intended for intramuscular use can cause tissue damage and slower absorption when given subcutaneously by mistake. Option d is incorrect because Massaging the site after injection is contraindicated with Z-track because it pushes medication out of the muscle. The seal created by the technique is meant to keep the medication within the muscle tissue.

Correct Answer: Pull lower lid down, drop into pocket

The nurse pulls the lower lid down to form a small pocket, drops the medication into the pocket without touching the eye, and applies gentle pressure to the inner canthus to limit systemic absorption. Option b is incorrect because Dropping directly onto the cornea can be uncomfortable and damaging, especially with an abrasion. The conjunctival sac receives the drop instead, and gentle eye closure spreads the medication across the surface. Option c is incorrect because Touching the dropper tip to the eye contaminates the bottle and can scratch the cornea. The nurse keeps the tip clear of the eye and lashes during instillation to maintain sterility and avoid injury. Option d is incorrect because Rapid blinking right after instillation flushes the medication out before it can be absorbed. Slow gentle eye closure with pressure to the inner canthus is preferred for several minutes after the drop instead.

Correct Answer: Rotate within an area for consistent absorption

Rotation within a single anatomic area gives more consistent absorption than rotating between areas. The patient picks the abdomen, thigh, or upper arm and moves around within that area, leaving an inch between injections. Option a is incorrect because Using only one site causes lipohypertrophy and erratic absorption over time. The tissue thickens and stops absorbing insulin reliably, which leads to unpredictable glucose control and possible severe swings during therapy. Option b is incorrect because Random injection anywhere each day produces inconsistent absorption between body areas. Different anatomic sites absorb insulin at different rates, and the variability complicates glucose management for the patient unnecessarily during therapy. Option c is incorrect because Avoiding the abdomen unnecessarily eliminates one of the most reliable absorption sites. The abdomen is a preferred site for many insulins because of consistent and predictable absorption rates compared to limbs.

Correct Answer: Slow deep inhale, hold ten seconds

After triggering one puff into the spacer, the patient inhales slowly and deeply through the mouthpiece and holds the breath for about ten seconds. The technique allows the medication to settle in the lower airway. Option a is incorrect because Inhaling fast prevents medication from reaching the lower airways and shortens the breath hold. A slow inhale gives time for particles to travel deeper, and a longer breath hold allows them to settle properly. Option b is incorrect because Exhaling into the spacer pushes the medication out of the chamber. The patient should exhale before placing the lips on the spacer mouthpiece, then trigger the puff and inhale slowly through the mouthpiece. Option d is incorrect because Taking five rapid puffs in a row delivers more medication than ordered and does not allow the lung to absorb each dose. Each puff is taken separately with proper technique and timing between attempts.
