Correct Answer: A

Rationale: To calculate the IV infusion rate in gtt/min: 1000 mL / 480 min 10 gtt/mL = 20.83 ≈ 21 gtt/min. Therefore, the correct answer is A. Choice B (20 gtt/min) is incorrect because the calculation results in 20.83 gtt/min, rounded to 21. Choices C (25 gtt/min) and D (18 gtt/min) are incorrect as they are not the closest whole number approximation to the calculated value.

Correct Answer: D

Rationale: The correct answer is to take hydrochlorothiazide in the morning. This medication is usually advised to be taken in the morning to prevent nocturia, which is excessive urination at night. Option A is incorrect because hydrochlorothiazide should be taken daily as prescribed, not as needed for edema. Option B is incorrect as monitoring weight weekly may not be specifically related to hydrochlorothiazide therapy. Option C is incorrect as hydrochlorothiazide does not need to be taken on an empty stomach.

Correct Answer: A

Rationale: To calculate the mL needed, set up a proportion: 5 mg / 1 mL = 2.5 mg / X mL. Cross multiply to find X: 5 * X = 2.5 * 1, X = 2.5 / 5 = 0.5 mL. Therefore, the nurse should administer 0.5 mL. Choice B, 0.005 mL, is incorrect as it doesn't match the calculated result. Choice C, 0.05 mL, is incorrect as it is ten times the correct value. Choice D, 5 mL, is incorrect as it represents the total volume of the entire vial, not the amount needed for the specific dose.

Correct Answer: A

Rationale: The correct answer is to administer the medication to the client before breakfast in the morning. Alendronate should be taken on an empty stomach before breakfast to ensure optimal absorption. Choice B is incorrect because assisting the client to a chair is not directly related to the administration of alendronate. Choice C is incorrect as there is no specific requirement to avoid taking alendronate with milk. Choice D is also incorrect as the priority at this moment is the correct administration of the medication in the hospital setting.

Correct Answer: C

Rationale: The correct answer is C: Hypotension. Enalapril, an ACE inhibitor, can lead to hypotension, especially after the first dose. Choices A, B, and D are incorrect because enalapril is not typically associated with ecchymosis, jaundice, or hypokalemia as common adverse effects. Therefore, the nurse should primarily monitor the client for signs of hypotension.
