Question 1 of 5

The nurse administers risedronate to a client with osteoporosis at 0700. The client asks for a glass of milk to drink with the medication. Which action should the nurse take?

Correct Answer: A

Rationale: Risedronate, a bisphosphonate, must be taken with plain water on an empty stomach, 30 minutes before food or beverages (
A) to ensure absorption (matches 55-Q1/16). Milk (
B) contains calcium, reducing efficacy. Delaying until breakfast (
C) or post-meal dosing (
D) violates guidelines.

Question 2 of 5

A client 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? (Enter Calculation(ans only)al value only. If rounding is required, round to the nearest whole number.)

Your Answer:

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 (matches 55-Q54). This ensures accurate azithromycin delivery.

Question 3 of 5

A client has a new prescription for zolpidem, a hypnotic. The client tells the home health nurse that he plans to take a dose of the medication during the day because he is exhausted and needs to take a short afternoon nap prior to an evening activity in his home. Which action should the nurse take?

A. Encourage the client to wait until bedtime to take the medication. B. Remind the client to drink plenty of fluids when taking the medication. C. Advise the client to take the medication with the noon meal. D. Explain that the client needs to allow for sleep time of at least two hours.

Correct Answer: A

Rationale: Zolpidem should be taken at bedtime (
A) to avoid daytime drowsiness and fall risk (matches 55-Q4). Fluids (
B) are unrelated. Noon meal dosing (
C) reduces efficacy. Two hours (
D) is insufficient for clearance.

Question 4 of 5

A client with Parkinson's disease who is taking carbidopa/levodopa reports that urine appears to be darker in color. Which action should the nurse take?

A. Encourage an increase in oral intake. B. Measure the client's urinary output. C. Explain that color change is normal. D. Obtain a specimen for a urine culture.

Correct Answer: C

Rationale: Carbidopa/levodopa can darken urine (
C), a benign side effect (matches 55-Q37). Increased fluids (
A) or urine culture (
D) are unnecessary unless other symptoms arise. Measuring output (
B) doesn’t address the color change.

Question 5 of 5

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

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

Correct Answer: A

Rationale: Vancomycin peak is typically drawn 1 hour post-infusion, trough 30-60 minutes pre-dose (matches 55-Q30/38, answer
B). Option A may overestimate peak but is provided as correct. Other timings (C,
D) miss accurate concentrations. Note: Confirm if B is intended.
