Correct Answer: Hyperosmolar hyperglycemic syndrome with severe dehydration

Extreme hyperglycemia with a very high osmolality and no ketones in an older adult with type 2 diabetes is hyperosmolar hyperglycemic syndrome. Enough insulin remains to block ketone formation, so acidosis does not develop. Option a is incorrect because ketoacidosis requires ketones, and this client's urine ketones are negative. Infection can precipitate either crisis, but without ketosis and acidosis the diagnosis cannot be ketoacidosis no matter what triggered it. Option b is incorrect because the glucose is extremely high rather than low. Confusion appears in both states, which is why a number is needed, and here the number points away from an insulin excess. Option d is incorrect because poor intake alone would not raise the glucose to these levels. Dehydration here is the consequence of an osmotic diuresis driven by hyperglycemia, so naming it as the cause misses the emergency.

Correct Answer: Give the insulin when the tray arrives

Rapid-acting lispro has an onset of about fifteen minutes, so it is given when food is in front of the client regardless of the scheduled time. That matches the insulin peak to the carbohydrate. Option b is incorrect because giving rapid-acting insulin before the food arrives sets up hypoglycemia. Trays run late often enough that the insulin can peak with no carbohydrate to cover, which is a real safety problem. Option c is incorrect because the mealtime dose covers this meal and skipping it leaves the postprandial rise untreated. A delayed tray is a timing problem, not a reason to omit prescribed coverage. Option d is incorrect because waiting an hour lets the glucose climb well before the insulin begins to work. The result is hyperglycemia after the meal, the mirror image of dosing too early.

Correct Answer: Set up oxygen and suction at the bedside.

Gathering and setting up equipment is a supportive task within the assistant's role. The nurse keeps the assessments, the sign testing and the teaching, because each requires nursing judgment and licensed evaluation. Option a is incorrect because judging voice quality is an assessment of laryngeal nerve function. Interpreting what a weak or changed voice means after neck surgery sits squarely with the registered nurse. Option b is incorrect because eliciting that sign is a screening assessment for low calcium, and the result must be interpreted immediately. Assessment cannot be handed to unlicensed staff no matter how experienced they are. Option d is incorrect because client teaching stays with the nurse under every delegation guideline. The assistant may remind a client of instructions already given, but the initial instruction itself is not delegable.

Correct Answer: Compare the month against missed care and incidents

A favorable salary variance produced by running short is a safety problem wearing a green number. The manager investigates the cause first, cross-checking overtime, missed care, incident reports and client outcomes before drawing any conclusion. Option a is incorrect because celebrating the number skips the question of how it was produced. Unfilled shifts mean hours the clients needed were never worked, and the omissions surface later as harm. Option b is incorrect because locking in a lower budget would make an unsafe staffing level permanent. A budget should be built on the hours the workload requires, not on the hours a vacancy happened to save. Option c is incorrect because moving money between lines answers no question about what happened. Nothing has yet been explained, and the nursing process applies here too, which means assessing the cause before intervening.

Correct Answer: I will increase my steroid dose when I run a fever.

Illness raises the body's cortisol requirement, and a client whose adrenal glands cannot respond must supply it. Doubling or tripling the usual dose during fever for a few days prevents adrenal crisis. Option a is incorrect because stopping the drug is the single most dangerous thing this client can do. Fever is a stressor that increases demand, and withdrawal at that moment invites profound hypotension and shock. Option b is incorrect because cutting the dose moves in exactly the wrong direction on a sick day. Replacement is meant to mimic the surge a healthy adrenal gland would produce under physical stress. Option d is incorrect because appetite has no bearing on how much cortisol the body needs. Doses are never skipped, and vomiting or diarrhea calls for an injected form rather than for missing the tablet.

Correct Answer: I will keep sugar-free candy handy for low readings.

Sugar-free candy contains no glucose and cannot raise a falling blood sugar. The client needs a simple sugar such as glucose tablets, regular soda or juice, carried at all times for a low. Option a is incorrect because checking before and after activity is exactly what the nurse wants. Exercise lowers glucose, and monitoring on both sides of the walk lets the client act before symptoms appear. Option b is incorrect because glucose tablets are the fast-acting carbohydrate clients are taught to keep within reach. Carrying them, along with identification, is a standard safety measure rather than an error needing correction. Option c is incorrect because a snack before activity supplies the carbohydrate that exercise will burn. Walking before breakfast on no food is a common cause of a low, so this plan prevents the problem.

Correct Answer: Coach the nurses and repair the scanners.

Scanning a printed sheet is at-risk behavior, a shortcut whose danger the nurses do not recognize because the safe route is broken. The response is coaching plus fixing the scanner so the safe way is the easy way. Option b is incorrect because suspension treats drift as recklessness and skips the broken equipment entirely. Nurses removed from the schedule are replaced by others who will meet the same failed scanner and find the same workaround. Option c is incorrect because restating a policy staff already know changes nothing about the conditions that defeat it. Education is the weakest intervention available, and here it asks nurses to comply with a technology that fails. Option d is incorrect because board referral is for conduct that endangers clients through deliberate disregard or impairment. A workaround built around defective equipment is a system failure, and reporting it upward would silence future disclosure.

Correct Answer: These findings are expected side effects

Nausea, diarrhea, bloating and a metallic taste are anticipated metformin effects that ease with a low starting dose, slow titration and taking the drug with food. They do not signal toxicity requiring the drug to stop. Option a is incorrect because an allergic reaction would show as rash, urticaria or swelling. Rash is in fact the classic planted distractor for metformin, since gastrointestinal upset and taste change are not immune-mediated events. Option b is incorrect because lactic acidosis announces itself differently, with malaise, muscle aches, unusual drowsiness, deep breathing and abdominal pain. The rare boxed-warning event is a systemic collapse, not the ordinary stomach upset described here. Option c is incorrect because gastrointestinal complaints worsen as the dose rises rather than signaling too little drug. Adequacy of the dose is judged by the A1C over two to three months, not by symptoms.

Correct Answer: An action plan targeting system weaknesses

A root cause analysis digs from the bedside to the organizational decisions behind an event and produces an action plan. Each action carries a responsible owner, a deadline, and a measure of whether it worked. Option a is incorrect because naming the person is the point at which such an investigation has failed. The method asks why the event was possible, not who was standing there when it happened. Option b is incorrect because performance review is a personnel process run by the manager on a separate track. Mixing discipline into a safety investigation destroys the candor that makes the investigation worth conducting at all. Option d is incorrect because a document that describes the event without committing anyone to change is precisely the outcome that led to the redesigned approach known as root cause analysis and action. Findings alone fix nothing.

Correct Answer: The second client fits the picture of SIADH.

SIADH is the euvolemic form of low sodium. Normal turgor, absent edema and weight gain without swelling fit it, while edema, distended neck veins and crackles mark hypervolemic hyponatremia from heart failure. Option b is incorrect because visible fluid overload rules the syndrome out. Absence of both volume depletion and edema is a required criterion, so a client with crackles and distended veins fails it. Option c is incorrect because treatment follows volume status, not the sodium number alone. The overloaded client needs sodium and fluid limits plus a diuretic aimed at the underlying pump failure. Option d is incorrect because a single value cannot separate these two clients; both are below range. Volume assessment is what sorts euvolemic from hypervolemic hyponatremia and decides which therapy is safe.

Correct Answer: Console the nurse and separate the vials.

This is human error, an inadvertent slip during a familiar task. The just culture response is to console the nurse and fix the system by separating the bins, adding tall man lettering, and reducing interruptions. Option a is incorrect because formal warnings are reserved for conscious disregard of a substantial risk. Punishing a slip leaves the adjacent bins exactly as they were and teaches the unit that reporting ends badly. Option b is incorrect because retraining sits at the weakest end of the intervention hierarchy and assumes a knowledge gap. This nurse already knew the drug; attention failed under interruption, which education cannot prevent. Option c is incorrect because coaching belongs to at-risk behavior, where someone chose a shortcut without recognizing the danger in it. No shortcut was chosen here, so there is no risky habit to redirect.

Correct Answer: Reduce stimulation and apply cooling measures without aspirin.

A quiet, dim, cool environment calms an overdriven nervous system, and hyperthermia must be brought down. Aspirin is avoided because it displaces thyroid hormone from its binding proteins and raises the free level. Option b is incorrect because aspirin raises free hormone and worsens the crisis. Restraints add struggle and heat production to a client whose metabolism is already dangerously accelerated, so both parts of the action are harmful. Option c is incorrect because stopping synthesis is central to survival here, and fever is a reason to treat harder rather than to hold the drug. Propylthiouracil is favored because it also blocks peripheral conversion. Option d is incorrect because iodine given ahead of the thionamide supplies raw material for still more hormone. It follows the antithyroid drug by at least an hour so that it blocks release only.

Correct Answer: Glargine is never mixed with any other insulin.

Long-acting insulins such as glargine and detemir are never mixed with another insulin. Their pH would alter the action of the other product, so glargine is given as a separate injection at the same time daily. Option a is incorrect because drawing order applies to the pairing of a clear short or rapid insulin with cloudy NPH. No order of withdrawal makes a long-acting insulin safe to combine in one syringe. Option b is incorrect because a pen delivers a single product and offers no way to blend two insulins. Premixed formulations exist, but they pair short or rapid insulin with NPH rather than with glargine. Option d is incorrect because speed of injection does not undo the chemical incompatibility. Once the two solutions meet in the syringe the action of both becomes unpredictable, which defeats the flat basal profile glargine provides.

Correct Answer: Acromegaly from growth hormone excess after puberty

Once the epiphyseal plates have fused, extra growth hormone thickens bone instead of lengthening it. Enlarging hands, feet, jaw and facial features in an adult is the picture of acromegaly. Option a is incorrect because gigantism requires open growth plates, which is why it develops in childhood and produces excessive height. This client reached skeletal maturity long before the hormone excess began. Option c is incorrect because dwarfism follows a deficiency of growth hormone, giving short stature with normal body proportions in a child. The described client has too much hormone, not too little. Option d is incorrect because hypopituitarism names a shortage of one or more pituitary hormones and would not enlarge the hands and face. The stem describes an overproducing gland, most often a functioning adenoma.

Correct Answer: The first has ketoacidosis and the second hyperosmolar syndrome

Kussmaul respirations and acetone breath are manifestations of the metabolic acidosis of ketoacidosis, which occurs in type 1 diabetes. Hyperosmolar syndrome occurs in older adults with type 2 diabetes, producing extreme dehydration without acidosis. Option b is incorrect because it reverses the two pictures. The client blowing off carbon dioxide with fruity breath is acidotic, and acidosis never belongs to hyperosmolar syndrome, where enough insulin remains to suppress ketone formation. Option c is incorrect because hyperosmolar syndrome produces no Kussmaul breathing and no acetone odor. Assigning that label to the young client ignores the single feature that separates the two emergencies, which is acidosis. Option d is incorrect because the older client breathes normally and shows no ketone signs. Ketoacidosis is largely a type 1 event driven by absent insulin, while this client retains enough insulin to prevent ketosis.

Correct Answer: Thyroid stimulating hormone rises to push the gland.

Negative feedback means falling thyroid hormone releases the pituitary from inhibition, so thyroid stimulating hormone climbs in an effort to drive the failing gland. High thyroid stimulating hormone with low free thyroxine defines primary hypothyroidism. Option a is incorrect because a falling pituitary hormone level belongs to secondary disease, where the pituitary itself is damaged. When the thyroid is the failing organ, the pituitary is intact and responds by secreting more. Option b is incorrect because an unchanged value would mean no feedback loop exists at all. Circulating thyroxine normally inhibits the pituitary, so any drop in thyroxine must change the signal it sends. Option d is incorrect because feedback is not lost when a gland fails; it is the loss of inhibition that drives the pituitary harder. The hormone becomes measurably elevated rather than absent from the blood.

Correct Answer: Diabetes insipidus from antidiuretic hormone deficiency

Pituitary surgery removes the store of antidiuretic hormone, so water is not reabsorbed. Huge volumes of dilute urine with a falling blood pressure are the expected picture of diabetes insipidus. Option a is incorrect because that syndrome produces the opposite urinary picture, with scant concentrated urine and a diluted serum sodium. It can follow pituitary surgery, but nothing in this report fits it. Option b is incorrect because adrenal crisis is driven by cortisol deficiency and shows shock with abdominal pain, vomiting and a high potassium. Massive dilute urine output is not one of its features. Option c is incorrect because thyrotoxicosis announces itself with fever, severe tachycardia, agitation and hypertension. Pale high-volume urine with a dropping pressure points toward water loss, not toward a hypermetabolic thyroid state.

Correct Answer: A sentinel event, regardless of the harm

Wrong-site surgery appears on the reviewable list and counts as a sentinel event whether or not the client was hurt. The event itself signals a catastrophic system failure and requires a full analysis and action plan. Option a is incorrect because nothing was intercepted here. A near miss stops before reaching the client, whereas this procedure was completed on the wrong limb and the client underwent surgery he did not need. Option c is incorrect because that category covers delays and dissatisfaction, such as a cold meal tray or a late transport. Operating on the wrong knee is a catastrophic clinical failure, not a lapse in service quality. Option d is incorrect because a hazardous condition raises the chance of harm before any client is involved, like a broken bed rail or an unlabeled syringe. The unsafe circumstance here already produced a completed wrong procedure.

Correct Answer: My eyes need a dilated exam right away.

In type 2 diabetes the disease has usually been present for years before diagnosis, so a dilated eye examination is done at diagnosis and then annually. Kidney and foot screening also begin at diagnosis. Option a is incorrect because the five year delay applies to type 1 diabetes, where the date of onset is known. Type 2 is often silent for years, so retinopathy may already be present at diagnosis. Option b is incorrect because waiting for edema means waiting until kidney damage is advanced. Early nephropathy is silent, which is why an annual albumin to creatinine ratio and an estimated filtration rate are obtained. Option d is incorrect because neuropathy removes the pain that would otherwise warn of injury. Feet are examined at least yearly with a monofilament and inspected by the client daily, precisely because they may never hurt.

Correct Answer: Discuss the workload and staffing with the director

Mandatory overtime converts a systemic staffing failure into one person's problem. The correct step is to raise the workload and staffing with the director, acknowledge the effects of exhaustion, and plan for resource reallocation. Option a is incorrect because absorbing it silently is what allows the problem to continue. Fatigue at this level raises error risk and drives burnout, and nothing changes until the shortfall is named to someone who can act. Option b is incorrect because leaving skips every step that might fix the situation. Resignation also worsens the vacancy that produced the overtime, and replacement costs the organization far more than addressing the workload would. Option c is incorrect because pushing the same fatigue onto the staff multiplies the risk instead of resolving it. Requiring extra hours without conversation is the very practice that made this manager exhausted.
