Question 1: A nurse is caring for a client with heart failure. Which finding requires
immediate intervention?
A. Weight gain of 1 kg in 3 days
B. Bilateral crackles in lower lungs
C. Heart rate of 88 bpm
D. Urine output of 30 mL/hr
Answer: B
Rationale: Bilateral crackles indicate pulmonary congestion and possible
worsening heart failure or pulmonary edema, which is life-threatening and
requires immediate intervention. The other findings are expected or within
acceptable limits.
Question 2: Which action is most important when administering IV potassium
chloride?
A. Give IV push slowly
B. Administer via peripheral line only
C. Ensure urine output is adequate before administration
D. Mix with dextrose solution
Answer: C
,Rationale: Potassium is excreted by the kidneys. If urine output is inadequate,
potassium can accumulate and cause fatal dysrhythmias. Therefore, ensuring
adequate kidney function is the priority.
Question 3: A client has tuberculosis. Which isolation precaution is required?
A. Contact
B. Droplet
C. Airborne
D. Protective (reverse)
Answer: C
Rationale: Tuberculosis spreads through airborne droplet nuclei, requiring
airborne precautions including N95 respirator and negative pressure room.
Question 4: Which lab value indicates hypoglycemia?
A. 45 mg/dL
B. 90 mg/dL
C. 110 mg/dL
D. 150 mg/dL
Answer: A
Rationale: A blood glucose level below 70 mg/dL indicates hypoglycemia. A level
of 45 mg/dL is significantly low and requires immediate treatment.
Question 5: A post-operative client is at highest risk for which complication?
A. Hypertension
B. Deep vein thrombosis
C. Hyperglycemia
D. Bradycardia
,Answer: B
Rationale: Post-surgical clients are at high risk for DVT due to immobility,
hypercoagulability, and venous stasis. Early ambulation and anticoagulants are
preventive measures.
Question 6: Which symptom is a sign of opioid overdose?
A. Hypertension
B. Respiratory depression
C. Tachycardia
D. Dilated pupils
Answer: B
Rationale: Opioid overdose causes central nervous system depression leading to
respiratory depression, which is the most dangerous and life-threatening
symptom.

correct?
A. “Shake NPH insulin vigorously before use.”
B. “Regular insulin is cloudy in appearance.”
C. “Clear insulin is drawn before cloudy insulin.”
D. “Insulin can be stored at any temperature.”
Answer: C
Rationale: When mixing insulins, clear (regular) insulin must be drawn up before
cloudy (NPH) insulin to prevent contamination.

, A. Post-op client with pain 4/10
B. Client with asthma and wheezing
C. Client with diabetes and glucose 140 mg/dL
D. Client with migraine headache
Answer: B
Rationale: Airway issues such as wheezing in asthma indicate impaired
breathing and take priority based on ABCs (Airway, Breathing, Circulation).
Question 9: Which electrolyte imbalance causes muscle twitching and tetany?
A. Hyperkalemia
B. Hypocalcemia
C. Hypernatremia
D. Hypermagnesemia
Answer: B
Rationale: Hypocalcemia increases neuromuscular excitability, leading to muscle
spasms, twitching, and tetany.
Question 10: A client is receiving warfarin therapy. Which lab should be
monitored?
A. aPTT
B. INR
C. Hemoglobin
D. Platelets
Answer: B
Rationale: INR is used to monitor therapeutic effectiveness of warfarin and
ensure safe anticoagulation levels.
