Question 1 of 5
After receiving five doses of filgrastim, the nurse notes that the client's white blood cell count has increased from 2,500/mm3 (2.5 x 109/L) to 5,000/mm3 (5 x 109/L). Which action should the nurse implement?
Correct Answer: B
Rationale: Filgrastim stimulates white blood cell production. An increase to 5,000/mm3 (
B) indicates effectiveness (matches 55-Q11). Neutropenic precautions (
A) are unnecessary. Culture reports (
C) and vital signs (
D) don’t assess filgrastim’s efficacy.
Question 2 of 5
The nurse prepares to administer a scheduled dose of labetalol by mouth to a client with hypertension. The client's vital signs are temperature 99°F (37.22°C), heart rate 48 beats/minute, respirations 16 breaths/minute, and blood pressure (B/P) 150/90 mm Hg. Which action should the nurse take?
Correct Answer: D
Rationale: Labetalol, a beta-blocker, can worsen bradycardia (48 bpm). Withholding the dose and notifying the provider (
D) is safest (matches 55-Q41). Administering (
B) risks exacerbating bradycardia. Orthostatic hypotension (
A) and telemetry (
C) are secondary.
Question 3 of 5
The nurse is planning care for a client with major depression who is receiving a new prescription for duloxetine. Which information is most important for the nurse to obtain?
Correct Answer: D
Rationale: Duloxetine is metabolized by the liver, and impaired liver function increases toxicity risk (
D) (matches 55-Q40). Liver function tests are critical. Other antidepressants (
A), weight changes (
B), and family history (
C) are relevant but secondary.
Question 4 of 5
The nurse is administering sodium polystyrene sulfonate to a client in acute kidney injury (AKI). Which laboratory finding indicates that the medication has been effective?
Correct Answer: C
Rationale: Sodium polystyrene sulfonate treats hyperkalemia. A potassium level of 3.8 mEq/L (
C) indicates effectiveness (matches 55-Q45). Hemoglobin (
A), glucose (
B), and ammonia (
D) are unrelated.
Question 5 of 5
The nurse receives a prescription for ciprofloxacin 400 mg intravenously (IV) every 12 hours to be infused over an hour. The IV bag contains ciprofloxacin 400 mg in dextrose 5% in water (D5W) 200 mL. The nurse should program the infusion pump to deliver how many mL/hr? (Enter Calculation(ans only)al value only.)
Correct Answer: 200
Rationale: Infusion rate: 200 mL / 1 hr = 200 mL/hr (matches 55-Q55). The pump should deliver 200 mL/hr for correct ciprofloxacin administration.
