Question 1 of 5

A client who is taking dextroamphetamine-amphetamine extended-release tablets for attention deficit hyperactivity disorder (ADHD), reports about having difficulty sleeping at night. Which assessment is most important for the nurse to obtain?

Correct Answer: C

Rationale: Dextroamphetamine-amphetamine, a stimulant, can cause insomnia if taken late. Determining dose timing identifies if adjusting to earlier administration reduces sleep issues. Caffeine, bedtime routines, or anxiety are secondary considerations.

Question 2 of 5

The nurse is teaching a client who has been diagnosed with human immunodeficiency virus (HIV) about the antiretroviral medication regimen. Which statement provided by the client requires additional instruction by the nurse?

A. The viral load can be decreased to an undetectable level. B. Antiretroviral medication prevents the transmission of the virus. C. The medications can decrease acquired immunodeficiency syndrome (AIDS) related complications. D. HIV infection is not cured by the antiretroviral regimen.

Correct Answer: B

Rationale: Antiretrovirals reduce viral load and transmission risk but do not fully prevent HIV transmission; safe practices are still needed. The other statements are accurate regarding HIV management and ART benefits.

Question 3 of 5

A female client with a history of peptic ulcer disease receives a prescription for misoprostol. Which information provided by the client indicates to the nurse a need for further teaching?

A. Begin therapy 1 week before the next normal menstrual cycle. B. Call the healthcare provider immediately if there is a chance of conception. C. Use condoms and a backup method of birth control to prevent pregnancy. D. Ensure a negative pregnancy test result 2 weeks before therapy.

Correct Answer: A

Rationale: Misoprostol’s administration is not tied to menstrual cycles; it’s used to prevent NSAID-induced ulcers and requires no specific cycle timing. Contacting providers for conception risks, using contraception, and confirming negative pregnancy tests are critical due to teratogenic risks.

Question 4 of 5

The healthcare provider prescribes magnesium sulfate 300 mg/hour IV. The IV bag contains magnesium sulfate 4 grams in dextrose 5% in water (D5W) 500 mL. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Your Answer:

Correct Answer: 37.5

Rationale: Convert 4 grams to 4000 mg. Infusion rate = (300 mg/hr) ÷ (4000 mg/500 mL) = 300 × 500 ÷ 4000 = 37.5 mL/hr. The pump should be set to 37.5 mL/hr.

Question 5 of 5

The healthcare provider prescribes propylthiouracil (PTU) and Lugol's solution, a strong iodine solution, for a client with hyperthyroidism. How should the nurse schedule the administration of these medications?

A. Offer both drugs together with a meal. B. Administer iodine one hour before PTU. C. Schedule both medications at bedtime. D. Give parental dose once every 24 hours.

Correct Answer: B

Rationale: Lugol’s solution reduces thyroid hormone production rapidly, preparing the gland for PTU, which inhibits hormone synthesis. Administering iodine one hour before PTU optimizes treatment efficacy. Meal timing, bedtime scheduling, or parenteral dosing are incorrect.
