1. A client with heart failure is prescribed furosemide. Which laboratory value
should the nurse monitor most closely?
A. Serum sodium
B. Serum potassium
C. Serum calcium
D. Serum glucose
Answer: B. Serum potassium
Rationale: Furosemide is a loop diuretic that causes potassium wasting.
Hypokalemia can lead to cardiac dysrhythmias, so potassium levels must
be monitored closely.
2. The nurse is caring for a client with pneumonia who has a new prescription
for ceftriaxone. Which client history finding would cause the nurse to
question this order?
, A. Allergy to penicillin
B. History of asthma
C. Diabetes mellitus
D. Hypertension
Answer: A. Allergy to penicillin
Rationale: Ceftriaxone is a cephalosporin, and clients with a penicillin
allergy have a risk of cross-sensitivity. The nurse should verify the allergy
and notify the provider.
3. A client postoperatively day 1 after abdominal surgery reports nausea and
vomiting. Which action should the nurse take first?
A. Administer antiemetic as prescribed
B. Assess the surgical incision
C. Measure intake and output
D. Auscultate bowel sounds
Answer: B. Assess the surgical incision
Rationale: Nausea and vomiting increase intra-abdominal pressure, which
can stress the incision. The nurse should first assess the incision for
dehiscence or evisceration.
4. Which developmental task is most appropriate for the nurse to encourage
in a 4-year-old child?
A. Trust versus mistrust
B. Autonomy versus shame
C. Initiative versus guilt
D. Industry versus inferiority
Answer: C. Initiative versus guilt
Rationale: According to Erikson, preschool-age children (3–6 years) are in
the initiative versus guilt stage. The nurse should encourage exploration
and play.
5. A client with chronic obstructive pulmonary disease has an arterial blood
gas result of pH 7.30, PaCO2 55 mmHg, and HCO3 30 mEq/L. Which
interpretation is correct?
A. Uncompensated respiratory acidosis
B. Partially compensated respiratory acidosis
, C. Uncompensated metabolic alkalosis
D. Fully compensated respiratory acidosis
Answer: B. Partially compensated respiratory acidosis
Rationale: The low pH and elevated PaCO2 indicate respiratory acidosis.
The HCO3 is elevated (compensatory), but the pH remains low, indicating
partial compensation.
6. The nurse is teaching a client with type 2 diabetes about foot care. Which
statement indicates the need for further teaching?
A. "I will wear white cotton socks every day."
B. "I will soak my feet in hot water daily."
C. "I will check my feet for blisters each evening."
D. "I will apply lotion to my feet but not between my toes."
Answer: B. "I will soak my feet in hot water daily."
Rationale: Soaking feet in hot water can cause burns and skin breakdown.
The client should wash feet with warm water and dry thoroughly.
7. A client receiving warfarin has an international normalized ratio of 4.5.
Which assessment finding is most concerning?
A. Bruising on the arms
B. Bleeding gums
C. Hematuria
D. Headache with confusion
Answer: D. Headache with confusion
Rationale: An INR of 4.5 indicates increased bleeding risk. Headache with
confusion may indicate intracranial hemorrhage, a medical emergency.
8. The nurse is preparing to administer a blood transfusion. Which action is
essential before initiating the transfusion?
A. Warm the blood to room temperature
B. Verify the client's identity and blood product with another nurse
C. Administer diphenhydramine prophylactically
D. Start a second intravenous line for emergency medications
Answer: B. Verify the client's identity and blood product with another nurse
Rationale: Two licensed nurses must verify the client's identity, blood
