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: A
Rationale: Late dosing of dextroamphetamine-amphetamine, a stimulant, can cause insomnia. Assessing dose timing identifies if earlier administration mitigates sleep issues. Bedtime routines, anxiety, or caffeine are secondary.
Question 2 of 5
The home health nurse observes a client self-administering an epinephrine injection using an auto-injector pen. Which client action requires intervention by the nurse?
Correct Answer: C
Rationale: Epinephrine auto-injectors are single-use devices. Cleansing for reuse risks contamination or malfunction, requiring intervention. Holding the pen in place ensures full dose delivery, the thigh is the correct site, and injecting through clothing is acceptable in emergencies.
Question 3 of 5
A client who is taking an oral contraceptive receives a new prescription for erythromycin. Which instruction should the nurse provide to the client?
Correct Answer: B
Rationale: Erythromycin may reduce oral contraceptive efficacy. Additional contraception (e.g., condoms) prevents pregnancy. Stopping contraceptives, spacing doses, or avoiding sunlight are incorrect.
Question 4 of 5
The nurse is administering sucralfate to a client with stomatitis secondary to chemotherapy. The client wants to take the medication after breakfast. How should the nurse respond?
Correct Answer: D
Rationale: Sucralfate forms a protective barrier over irritated stomach and intestinal areas, requiring an empty stomach for optimal effectiveness. Taking it at least 1 hour before meals ensures proper coating without food interference. Post-meal administration reduces efficacy, and documenting refusal is inappropriate without education.
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?
Correct Answer: B
Rationale: Lugol’s solution reduces thyroid hormone production, enhancing PTU’s inhibition of hormone synthesis. Administering iodine one hour before PTU optimizes efficacy. Bedtime, parenteral, or meal-time administration are incorrect.
