Question 1 of 5

A patient is receiving a secondary infusion of azithromycin 500 mg in 500 mL of normal saline (NS) to be infused over 2 hours. The intravenous (IV) administration set delivers 10 gtt/mL. How many gtt/min should the nurse regulate the infusion?

Correct Answer: 42

Rationale: Infusion rate: 500 mL / 2 hr = 250 mL/hr. Drops per minute: (250 mL/hr × 10 gtt/mL) / 60 min = 41.67, rounded to 42 gtt/min. This ensures accurate delivery of azithromycin.

Question 2 of 5

A patient with peptic ulcer disease has been prescribed cimetidine. Which statement made by the patient indicates the need for further instruction by the nurse?

A. Decrease cigarette use to a pack per day. B. Notify the healthcare provider of lethargy. C. Take the medication an hour after antacids. D. Monitor for any signs of sexual dysfunction.

Correct Answer: C

Rationale: Cimetidine should be taken with meals or immediately after, not 1 hour after antacids (
C), which interferes with absorption. Reducing smoking (
A) is insufficient; cessation is ideal. Lethargy (
B) and sexual dysfunction (
D) are valid monitoring points.

Question 3 of 5

A client has been prescribed 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. How many mL/hour should the nurse program the infusion pump to deliver? (Enter numerical value only.)

Your Answer:

Correct Answer: 200

Rationale: Infusion rate: 200 mL / 1 hr = 200 mL/hr. The pump should be set to deliver 200 mL/hr to administer ciprofloxacin correctly.

Question 4 of 5

A client is receiving intravenous vancomycin, and the nurse plans to draw blood for a peak and trough to determine the serum level of the drug. Which collection times would provide the best determination of these levels?

A. One hour after completion of the IV dose and one hour before the next administration of the medication. B. Two hours after completion of the IV dose and two hours before the next administration of the medication. C. Thirty minutes into the administration of the IV dose and 30 minutes before the next administration of the medication. D. Immediately after completion of the IV dose and 30 minutes before the next administration of the medication.

Correct Answer: A

Rationale: This question is identical to Question 30. Peak vancomycin levels are drawn 1 hour post-infusion, troughs 1 hour pre-dose (
A). Other timings (B, C,
D) miss accurate concentrations. Note: Duplicate question; consider removing.

Question 5 of 5

A client with benign prostatic hyperplasia has been prescribed tamsulosin. What should the nurse do to monitor for an adverse reaction?

A. Monitor the client’s blood pressure. B. Assess the client’s urine output. C. Perform a bladder scan. D. Obtain the client’s daily weights.

Correct Answer: A

Rationale: Tamsulosin, an alpha-blocker, can cause hypotension and dizziness (
A), requiring blood pressure monitoring. Urine output (
B) and bladder scans (
C) assess BPH, not adverse effects. Daily weights (
D) monitor fluid status, not tamsulosin risks.
