Question 1 of 5
A patient is being discharged on anticoagulant therapy. The nurse will include in the patient- education conversation that it is important to avoid herbal products that contain which substance?
Correct Answer: B
Rationale: Ginkgo is known to have anticoagulant properties that can interact with and enhance the effects of anticoagulant medications, such as warfarin. Therefore, patients taking anticoagulant therapy should avoid herbal products containing ginkgo to prevent excessive anticoagulation and the risk of bleeding complications. It is essential for healthcare providers to educate patients on potential herb-drug interactions to ensure their safety and optimal therapeutic outcomes.
Question 2 of 5
Androgen is secreted by
Correct Answer: C
Rationale: Androgens, primarily testosterone, are secreted by the testes' Leydig cells, stimulated by luteinizing hormone (LH) from the pituitary, making the testes the direct source. Follicle-stimulating hormone (FSH) from the pituitary regulates sperm production, not androgen secretion. Gonadotropin-releasing hormone (GnRH) from the hypothalamus triggers pituitary LH and FSH release, indirectly influencing androgen production, not secreting it. The pituitary releases LH and FSH, not androgens itself. The testes' role as the endocrine organ producing androgens is clear, driven by LH, and is fundamental to male reproductive and secondary sexual characteristics, setting it apart from regulatory hormones in the hypothalamic-pituitary-gonadal axis.

Question 4 of 5
The client takes calcium supplements. What is the best instruction by the nurse?
Correct Answer: B
Rationale: Calcium absorbs best with food-e.g., fat aids uptake, per pharmacokinetics-unlike empty stomach. Insomnia isn't typical-constipation is. Vitamin D matters-enhances absorption. Meal timing optimizes use, per guidance.
Question 5 of 5
Which patient would benefit from administration of simvastatin (Zocor) 80 mg?
Correct Answer: D
Rationale: In general, the maximum recommended dose of simvastatin is 40 mg daily due to an increased risk of myopathy, including rhabdomyolysis, at higher doses. However, in certain cases, especially for patients who have been tolerating and responding well to simvastatin 40 mg for an extended period without experiencing myopathy, increasing the dose to 80 mg may be considered. Patients who have been taking simvastatin for 12 months with no evidence of myopathy are likely to benefit from the higher dose in terms of better lipid control. It is important to monitor closely for any signs or symptoms of myopathy even with the 80 mg dose.
