A nurse is preparing to administer 1 mg vitamin K to a newborn. The medication is available in 1 mg/0.5 mL. How much should the nurse administer?
(Round to the nearest tenth. Use a leading zero when applicable. Do not use a trailing zero.)
The Correct Answer is ["0.5"]
Step 1: Determine the dosage required. Required dosage = 1 mg
Step 2: Determine the concentration of the available solution. Available concentration = 1 mg/0.5 mL
Step 3: Calculate the volume to be administered. Volume to be administered = Required dosage ÷ Available concentration Volume to be administered = 1 mg ÷ (1 mg ÷ 0.5 mL)
Step 4: Perform the division. 1 ÷ (1 ÷ 0.5) = 1 ÷ 2 = 0.5
Step 5: Round the answer to the nearest tenth. Rounded volume = 0.5 mL
The nurse should administer 0.5 mL.

Correct Answer is D
Explanation
Choice A reason: You Can Expect Swelling of the Ankles While Taking This Medication
Swelling of the ankles, or peripheral edema, is a known side effect of verapamil. This calcium channel blocker can cause fluid retention, leading to swelling in the lower extremities. While this is a common side effect, it is not an instruction that the nurse should include in discharge teaching. Instead, the nurse should inform the client to report any significant swelling to their healthcare provider.
Choice B reason: Do Not Take This Medication on an Empty Stomach
Verapamil can be taken with or without food, but taking it with food may help reduce stomach upset. Therefore, the instruction to avoid taking it on an empty stomach is not strictly necessary. The nurse should advise the client to follow their healthcare provider’s specific instructions regarding medication administration.
Choice C reason: Limit Your Fluid Intake to Meal Times
Limiting fluid intake to meal times is not a standard recommendation for clients taking verapamil. Adequate hydration is important for overall health, and there is no specific reason to restrict fluid intake while on this medication. The nurse should encourage the client to maintain a balanced fluid intake throughout the day.
Choice D reason: Increase Your Daily Intake of Dietary Fiber
Increasing daily intake of dietary fiber is a beneficial instruction for clients taking verapamil. Verapamil can cause constipation as a side effect, and a high-fiber diet can help mitigate this issue. Foods rich in fiber, such as fruits, vegetables, and whole grains, can promote regular bowel movements and improve digestive health.

Step 2: Determine the total time for infusion. = 2 hours
Step 3: Calculate the infusion rate in mL/hr. Calculation: 200 mL ÷ 2 hours = 100 mL/hr
