NUR 283 COMP 2 MOCK EXAM 2026 | 300 QUESTIONS
1. A nurse is caring for a client with heart failure who has an order for
furosemide (Lasix). Which electrolyte imbalance should the nurse monitor for
most closely?
A. Hypernatremia
B. Hypercalcemia
C. Hyperkalemia
D. Hypokalemia
E. Hypermagnesemia
Correct Answer: D. Hypokalemia
EXPERT RATIONALE: Furosemide is a loop diuretic that causes loss of
potassium in the urine. Hypokalemia (low serum potassium) is the most common
and dangerous electrolyte imbalance associated with its use, potentially leading to
cardiac dysrhythmias.
,2. A client is prescribed digoxin. Before administering the medication, the
nurse checks the apical pulse and finds it to be 54 bpm. What is the nurse's
priority action?
A. Administer the medication as prescribed
B. Administer half the prescribed dose
C. Document the finding and continue care
D. Notify the healthcare provider immediately
E. Hold the medication and notify the provider
Correct Answer: E. Hold the medication and notify the provider
EXPERT RATIONALE: Digoxin should be held if the apical pulse is below 60 bpm
in adults. Bradycardia is a sign of digoxin toxicity. The nurse must hold the dose
and notify the provider before administration.
3. A nurse is assessing a client with left-sided heart failure. Which finding is
most expected?
A. Peripheral edema
B. Ascites
C. Jugular vein distension
D. Hepatomegaly
E. Crackles in the lungs
Correct Answer: E. Crackles in the lungs
EXPERT RATIONALE: Left-sided heart failure causes fluid to back up into the
pulmonary circulation, resulting in pulmonary edema. Crackles (rales) heard on
auscultation are a hallmark sign of fluid accumulation in the alveoli.
,4. A client with chronic kidney disease has a potassium level of 6.2 mEq/L.
Which dietary instruction should the nurse provide?
A. Increase intake of bananas and oranges
B. Encourage potassium-rich foods for energy
C. Consume dairy products with each meal
D. No dietary changes are needed
E. Avoid high-potassium foods such as bananas, oranges, and potatoes
Correct Answer: E. Avoid high-potassium foods such as bananas, oranges,
and potatoes
EXPERT RATIONALE: Hyperkalemia (K+ >5.0 mEq/L) is dangerous and can lead
to life-threatening cardiac dysrhythmias. Clients with CKD must restrict potassium
intake and avoid foods high in potassium.
5. The nurse is caring for a postoperative client receiving morphine via PCA
pump. Which assessment finding requires immediate intervention?
A. Pain rating of 4/10
B. Respiratory rate of 18 breaths/min
C. Client requesting additional bolus doses
D. Mild nausea reported by client
E. Respiratory rate of 8 breaths/min
Correct Answer: E. Respiratory rate of 8 breaths/min
EXPERT RATIONALE: Opioids such as morphine cause respiratory depression. A
respiratory rate of 8 breaths/min indicates severe respiratory depression, which is
life-threatening and requires immediate intervention including naloxone
administration.
, 6. A nurse is teaching a client about warfarin therapy. Which statement by
the client indicates a need for further teaching?
A. "I will get regular INR blood tests."
B. "I will use a soft toothbrush."
C. "I will avoid alcohol."
D. "I will wear a medical alert bracelet."
E. "I can take ibuprofen for my headaches."
Correct Answer: E. "I can take ibuprofen for my headaches."
EXPERT RATIONALE: NSAIDs like ibuprofen increase the risk of bleeding when
taken with warfarin. Clients on anticoagulation therapy should use acetaminophen
for pain relief and avoid NSAIDs unless directed by their provider.
7. A client presents with a serum sodium level of 125 mEq/L. Which symptom
is the nurse most likely to assess?
A. Extreme thirst
B. Hypertension
C. Flushed dry skin
D. Decreased deep tendon reflexes
E. Confusion and headache
Correct Answer: E. Confusion and headache
EXPERT RATIONALE: A sodium level of 125 mEq/L indicates hyponatremia. The
brain is highly sensitive to sodium changes; low sodium causes cerebral edema,
leading to neurological symptoms such as confusion, headache, and in severe
cases, seizures.
