Question 1:
A patient in ventricular fibrillation remains pulseless despite multiple appropriate
defibrillation attempts and administration of epinephrine 1 mg IV every 3–5 minutes.
Which antiarrhythmic medication should the nurse practitioner anticipate
administering next according to ACLS guidelines?
A. Lidocaine
B. Adenosine
C. Amiodarone
D. Verapamil
Correct Answer: C. Amiodarone
Rationale: Amiodarone (Cordarone) is the recommended antiarrhythmic medication
for refractory ventricular fibrillation or pulseless ventricular tachycardia after
defibrillation and epinephrine have failed to restore a perfusing rhythm. It works
primarily by prolonging the cardiac action potential and slowing conduction through
potassium channel blockade. Lidocaine may be used as an alternative but is not
considered first-line in this scenario. Adenosine is indicated for supraventricular
tachycardia, not ventricular fibrillation. Verapamil is a calcium-channel blocker used
for certain supraventricular dysrhythmias and would worsen hemodynamic instability
in cardiac arrest.
Question 2:
The nurse evaluates improvement in a patient diagnosed with chronic heart failure
(HF). Which assessment finding most strongly suggests that the patient's condition
has improved?
A. Increased urine output
B. Using fewer pillows while sleeping
,2026/2027
C. Weight gain of 2 pounds
D. Heart rate of 102 bpm
Correct Answer: B. Using fewer pillows while sleeping
Rationale: Patients with worsening heart failure commonly experience orthopnea,
which forces them to sleep with multiple pillows to ease breathing. Improvement in
heart failure status is demonstrated when the patient can sleep comfortably with fewer
pillows, indicating reduced pulmonary congestion. Increased urine output may occur
temporarily with diuretic therapy but is not the most reliable indicator of overall
improvement. Weight gain usually suggests fluid retention and worsening HF.
Tachycardia may indicate inadequate cardiac compensation rather than improvement.
Question 3:
Which medication is most commonly prescribed for long-term anticoagulation in
patients with mechanical prosthetic heart valves?
A. Apixaban
B. Aspirin
C. Warfarin
D. Clopidogrel
Correct Answer: C. Warfarin
Rationale: Warfarin remains the standard anticoagulant for patients with mechanical
heart valves because it effectively reduces the risk of thromboembolic complications
associated with prosthetic valves. Direct oral anticoagulants such as apixaban are
generally contraindicated in mechanical valve patients due to increased thrombotic
risk. Aspirin and clopidogrel are antiplatelet agents and are insufficient as sole
therapy for mechanical valve anticoagulation. Warfarin therapy requires close INR
monitoring to maintain therapeutic effectiveness while minimizing bleeding risk.
Question 4:
A patient with untreated vitamin B12 deficiency anemia is at risk for which
complication?
A. Neurologic impairment
B. Cognitive dysfunction
C. Peripheral neuropathy
D. All of the above
Correct Answer: D. All of the above
Rationale: Vitamin B12 deficiency can cause significant hematologic and neurologic
complications if left untreated. Neurologic manifestations include peripheral
neuropathy, paresthesias, balance disturbances, and cognitive impairment. Severe
,2026/2027
deficiency may lead to irreversible nerve damage and neuropsychiatric symptoms.
Because vitamin B12 is essential for DNA synthesis and neurologic function,
untreated deficiency affects multiple body systems. Therefore, all listed complications
are possible outcomes.
Question 5:
Which medication is classified as an angiotensin-converting enzyme (ACE) inhibitor
and is commonly prescribed for hypertension?
A. Amlodipine
B. Metoprolol
C. Lisinopril
D. Hydrochlorothiazide
Correct Answer: C. Lisinopril
Rationale: Lisinopril is an ACE inhibitor frequently used to treat hypertension, heart
failure, and diabetic nephropathy. It lowers blood pressure by blocking conversion of
angiotensin I to angiotensin II, resulting in vasodilation and decreased aldosterone
secretion. Amlodipine is a calcium-channel blocker, metoprolol is a beta-blocker, and
hydrochlorothiazide is a thiazide diuretic. Although these medications may also treat
hypertension, they belong to different drug classes and have distinct mechanisms of
action.
Question 6:
A 49-year-old patient with angina is prescribed transdermal nitroglycerin patches
(Transderm-Nitro). Which adverse effect should the nurse practitioner most closely
monitor for?
A. Constipation
B. Bradycardia
C. Headache
D. Hyperglycemia
Correct Answer: C. Headache
Rationale: Headache is one of the most common adverse effects of nitroglycerin
therapy due to vasodilation of cerebral blood vessels. Patients frequently report
throbbing headaches when initiating nitrate therapy. Constipation and hyperglycemia
are not typical effects of nitrates. Bradycardia is less common; reflex tachycardia is
more likely to occur. Educating patients about expected headaches can improve
adherence to therapy.
Question 7:
, 2026/2027
Which hematocrit value falls within the normal range for a healthy 37-year-old adult
male?
A. 28%
B. 34%
C. 44%
D. 52%
Correct Answer: C. 44%
Rationale: The normal hematocrit range for adult males is generally approximately
42%–52%. A hematocrit of 44% falls comfortably within this range and suggests
adequate red blood cell volume. Values of 28% and 34% indicate anemia, while 52%
is at the upper limit and may suggest dehydration or polycythemia depending on
clinical context. Hematocrit values help assess oxygen-carrying capacity and
hydration status.
Question 8:
What is the recommended target hemoglobin concentration for patients with chronic
kidney disease receiving epoetin alfa or darbepoetin alfa therapy?
A. 8 g/dL
B. 9 g/dL
C. 11 g/dL
D. 15 g/dL
Correct Answer: C. 11 g/dL
Rationale: In patients with chronic kidney disease, erythropoiesis-stimulating agents
such as epoetin alfa and darbepoetin alfa are used to manage anemia. Current
recommendations generally target a hemoglobin level around 10–11 g/dL to reduce
symptoms while minimizing risks such as thrombosis, stroke, and cardiovascular
events. Attempting to normalize hemoglobin levels above this range has been
associated with adverse outcomes. Levels of 8–9 g/dL are typically too low and may
leave patients symptomatic.
Question 9:
Which medication should be administered first in the initial management of acute
coronary syndrome (ACS)?
A. Digoxin
B. Aspirin
C. Warfarin
D. Dopamine
