Correct Answer: Silent heart attack

Heart attacks that occur without any symptoms or with very mild symptoms are called silent heart attacks. They are more common in older adults and in people with high blood sugar or diabetes, matching this patient. Option a is incorrect because is a serious condition in which the heart cannot pump blood properly, which CAD can cause over time; it does not name a symptomless heart attack. Option b is incorrect because describes the process of plaque buildup inside the arteries, not a heart attack that occurs with no symptoms or very mild ones. Option d is incorrect because is a diagnostic procedure considered the gold standard for diagnosing CAD, so it is a test rather than a type of heart attack.

Correct Answer: Coronary angiography

Coronary angiography, along with coronary CT angiography, may be ordered to visualize strictures and plaque buildup within the coronary arteries. Laboratory tests assess cholesterol or inflammation, and carotid ultrasound examines carotid blood flow. Option a is incorrect because it is a laboratory test reflecting cholesterol buildup, so it gives blood values and does not visualize plaque or strictures in the coronary arteries. Option b is incorrect because it examines blood flow within the carotid arteries of the neck, not the coronary arteries of the heart. Option c is incorrect because this laboratory test relates to inflammation within the arteries and cannot show the location or extent of narrowing.

Correct Answer: Acute coronary syndrome

Acute coronary syndrome is the umbrella term for conditions causing a sudden decrease in oxygenated blood flow to the cardiac muscle, ranging from unstable angina, where pain does not resolve with rest or nitroglycerin, to myocardial infarction. Option a is incorrect because it is one of three zones of potential cardiac tissue damage, recognized on an ECG by ST segment depression, not a grouping of conditions. Option b is incorrect because it names one mechanism, a blood clot lodging in a coronary artery, rather than the umbrella term that spans unstable angina through infarction. Option d is incorrect because it is chronic and predictable, relieved with rest or nitroglycerin, and caused by partial blockage, so it does not match this presentation.

Correct Answer: I and II

Echocardiography is the most common test for diagnosing cardiomyopathy, and genetic testing can identify inherited types. Some people have no symptoms and may not need treatment, and treatments may not fix the heart problem. Option b is incorrect because statement IV is contradicted by NHLBI guidance, which says treatments may not fix the heart problem but can lower symptoms, slow progression and reduce the chance of sudden death. Option c is incorrect because statement III fails because some people with cardiomyopathy have no symptoms and may not need treatment, even though some providers recommend treatment to prevent progression. Option d is incorrect because both chosen statements are inaccurate: symptoms and treatment are not universal, and treatment does not promise a cure, while the two accurate diagnostic statements are left out.

Correct Answer: Left-sided heart failure

Orthopnea, paroxysmal nocturnal dyspnea, crackles in the lungs and decreased ejection fraction on echocardiogram are listed signs and symptoms of left-sided heart failure, where the left ventricle is the primary ventricle affected. Option a is incorrect because also called Wenckebach block, it is recognized by progressive PR interval prolongation followed by a dropped impulse, not by orthopnea or crackles. Option c is incorrect because it is a conduction finding defined by a prolonged PR interval on ECG and usually needs no treatment, not a lung-congestion picture. Option d is incorrect because it presents mainly with peripheral edema, ascites, hepatomegaly and jugular venous distension, none of which appear in this documentation.

Correct Answer: Hypertension Stage 3

The American Heart Association table lists Normal, Elevated (Prehypertension), Hypertension Stage 1, Hypertension Stage 2 and Hypertensive Crisis. No Stage 3 category appears, so Hypertension Stage 3 is not a classification. Option a is incorrect because the table places this category at the top, with systolic readings higher than 180 and diastolic readings higher than 120. Option b is incorrect because the table lists it for readings of 140 or higher systolic or 90 or higher diastolic, so it is a genuine classification. Option c is incorrect because it is a listed category covering systolic readings of 120-129 with diastolic readings below 80, sitting between normal and Stage 1.

Correct Answer: Blood pressure recorded on at least two separate occasions

Diagnostic testing for hypertension involves recording blood pressures on at least two separate occasions, with measurements taken in both arms while the client is seated and relaxed, so a single elevated reading is not enough. Option a is incorrect because measurement is described with the client seated and relaxed, in both arms, rather than standing. Option b is incorrect because providers typically repeat an elevated reading at another appointment before diagnosing, so one reading does not meet the diagnostic testing requirement. Option d is incorrect because an echocardiogram is an optional evaluation for organ damage in suspected cases, not the basic measurement needed for diagnosis.

Correct Answer: Venous stasis, hypercoagulability, and injury to a vein

Virchow's triad names three main pathophysiological mechanisms in the development of a DVT: venous stasis (slow blood flow), hypercoagulability, and injury to a vein. Option a is incorrect because these are examples of risk factors that lead to venous stasis or hypercoagulability, so they are causes within the mechanisms rather than the three mechanisms. Option b is incorrect because chronically elevated blood pressure is the definition of hypertension, and heart failure is only named as one cause of slow blood flow, not a triad member. Option c is incorrect because necrosis and plaque from atherosclerosis describe arterial insufficiency, a different condition, and are not among the mechanisms grouped as Virchow's triad for a DVT.

Correct Answer: Chronic inflammation and bronchoconstriction

Asthma is caused by chronic inflammation in the airways, which narrows air passages. Bronchoconstriction also tightens the smooth muscle surrounding the airways, further limiting airflow. Increased mucus may block the airways further. Option a is incorrect because pulmonary edema is fluid accumulation in the alveoli that causes hypoxia through inadequate ventilation; it is not described as a mechanism of asthma. Option c is incorrect because fluid in the alveoli and reduced tissue oxygenation belong to the description of hypoxia, while asthma involves airway inflammation and tightened smooth muscle. Option d is incorrect because these terms describe causes of hypoxia involving blood flow and ventilation balance, not the airway narrowing mechanism that defines asthma.

Correct Answer: Quick-relief inhalers

Quick-relief inhalers, such as albuterol and ipratropium, are one of the two major classes of asthma medication and are used to control symptoms that occur during an asthma attack. Option a is incorrect because they help prevent asthma attacks but do not resolve symptoms that occur once an attack is underway. Option b is incorrect because nurses teach this to help clients prevent attacks, so it is a preventive step rather than a medication class. Option c is incorrect because bicarbonate retention is a kidney compensation described for COPD acid-base changes, not a class of asthma medication.

Correct Answer: alveoli

Pneumonia is an infection of the alveoli of the lungs. Inflammation and infection within the alveoli cause them to fill with fluid or purulent material, producing cough, fever, chills, and difficulty breathing. Option a is incorrect because these airways are described as the site of inflammation in chronic bronchitis, one of the two conditions included in COPD, not in pneumonia. Option c is incorrect because destruction of lung elastic tissue, with loss of recoil and hyperinflation, defines emphysema, which is part of COPD rather than pneumonia. Option d is incorrect because destruction of these walls is listed as one reason for reduced airflow in COPD, so it describes a chronic obstructive process instead.

Correct Answer: Venous insufficiency

Venous insufficiency occurs when blood and fluid are not adequately returned from the extremities to the heart. Its signs are edema, a brownish-leathery appearance of lower-extremity skin, and venous ulcers that weep fluid. Option a is incorrect because burns come from intense heat, radiation, electricity or chemicals and are classified by depth of skin damage; blood pooling in the lower legs is not a burn mechanism. Option b is incorrect because a superficial burn, formerly first-degree, affects only the epidermis and typically heals on its own within a few days, so weeping ulcers do not fit. Option d is incorrect because pressure injuries are staged by extent of tissue damage, with Stage 4 meaning deep open ulcers reaching muscle, ligaments or tendons, not edema with brownish-leathery skin.

Correct Answer: partial thickness

A second-degree burn, affecting the epidermis and part of the dermis with swelling and painful blistering, is now called a partial thickness burn. The newer classification system replaced the historic degree-based names. Option a is incorrect because the name replaces fourth-degree and describes the most severe injury, reaching underlying muscle and bone, far deeper than the dermis portion described here. Option b is incorrect because this is the current name for a first-degree burn, which affects only the epidermis and does not involve any part of the dermis. Option c is incorrect because a burn given this name extends fully into the epidermis and dermis, destroying tissue and affecting nerve endings, which goes beyond blistering.

Correct Answer: Elevated platelet levels

A complete blood count may show elevated platelet levels with Crohn's disease. The guidance states this increases the client's risk for deep vein thrombosis, pulmonary embolism and cerebrovascular accident. Option a is incorrect because the guidance says these may occur with severe diarrhea and appear on the comprehensive metabolic panel, with no connection stated to the listed vascular events. Option b is incorrect because a comprehensive metabolic panel may show this when malnutrition is occurring, and the guidance links it to nutrition, not to deep vein thrombosis or stroke. Option d is incorrect because this stool study result may be elevated due to inflammation and helps in diagnosing IBD; the guidance ties it to inflammation, not to those vascular events.

Correct Answer: Portal hypertension

With repeated injury, most of the liver becomes fibrosed and loses function, which ultimately leads to portal hypertension, meaning elevated pressures in the blood vessels of the liver. The body then diverts blood to other veins. Option b is incorrect because it describes abdominal distension from fluid and is listed as a sign of hepatic decompensation, not as the pressure elevation itself. Option c is incorrect because it is a decompensation sign, confusion caused by liver failure, rather than the elevated vessel pressure that develops from fibrosis. Option d is incorrect because they are enlarged esophageal veins that bleed as a consequence of portal hypertension, so they follow from the pressure rather than name it.

Correct Answer: Stage 3, moderate reduction in GFR

The CKD staging table assigns a GFR of 30 to 59 mL/min/1.73 m² to Stage 3, described as a moderate reduction in GFR. A value of 45 falls inside that range. Option a is incorrect because this stage covers a GFR of 60 to 89, which is a higher range than the recorded value of 45. Option c is incorrect because it describes a GFR of less than 15, the lowest range, which is far from the value documented here. Option d is incorrect because this stage is reserved for GFR values from 15 to 29, well below the recorded value, so it overstates the loss of function.

Correct Answer: Remission and exacerbations

Rheumatoid arthritis is known for its pattern of remission and exacerbations, in which symptoms might improve and worsen intermittently. It is a chronic, systemic autoimmune disorder. Option a is incorrect because sudden loss from accident or severe injury describes traumatic amputation, not the course of an autoimmune joint disease. Option b is incorrect because rheumatoid arthritis is bilateral, affecting both sides of the body and often multiple joints at the same time. Option c is incorrect because the disease is chronic, and symptoms improve and worsen intermittently rather than resolving in a steady, uninterrupted way.

Correct Answer: Acute compartment syndrome

Severe, unrelenting pain disproportionate to the injury and unresponsive to opioids, with pale and cool skin, are warning signs among the six P's of acute compartment syndrome, which a tight cast can cause. Option b is incorrect because it is an autoimmune disease marked by bilateral joint pain, stiffness and swelling with remissions and exacerbations, not by pain unrelieved by opioids after casting. Option c is incorrect because it is a small crack in a bone, a fracture type, and does not explain pallor, cool skin and pain disproportionate to the injury. Option d is incorrect because its symptoms center on inability to bear weight, a shortened and outwardly rotated leg, and bruising around the hip, which this excerpt does not describe.

Correct Answer: Not permissible; only codes may be reported

The convention on use of codes for reporting purposes states that only codes are permissible, not categories or subcategories. A three-character category with further subdivision is not a code, so it cannot be reported. Option a is incorrect because provider approval is not a condition in the conventions; the rule on reporting rests on the classification's structure, not on a provider's preference. Option b is incorrect because the guidelines apply conventions to all health care settings unless otherwise indicated, and they do not give outpatient reporting an exception for categories. Option d is incorrect because a 7th character applies only to codes that have one in the Tabular List, and adding it to a category does not make it a code.

Correct Answer: Procedure coding and reporting

The guidelines have four sections: Section I (conventions, general and chapter-specific guidelines), Section II (principal diagnosis), Section III (additional diagnoses) and Section IV (outpatient). None of them is a section on procedure coding and reporting. Option a is incorrect because this is Section II, which holds the guidelines for selecting the principal diagnosis in non-outpatient settings, so it is a genuine section. Option c is incorrect because Section III covers reporting of additional diagnoses in non-outpatient settings, which makes it a real part of the guidelines' organization. Option d is incorrect because Section IV is devoted to outpatient coding and reporting, so it belongs among the guideline sections.
