Question 1 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 2 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 3 of 5
Lithium is used to?
Correct Answer: C
Rationale: Lithium is commonly used as a mood stabilizer in the treatment of bipolar disorder. It helps reduce the intensity of manic episodes, thereby stabilizing the patient's mood and preventing extreme mood swings. While lithium is primarily known for its mood-stabilizing effects, it is not used to lower blood glucose, slow the heart, or heal ulcers.
Question 4 of 5
The nurse is caring for a client receiving amphotericin B for a fungal infection. Which adverse effect should the nurse monitor closely?
Correct Answer: A
Rationale: Amphotericin B, an antifungal, is nephrotoxic , damaging renal tubules and reducing GFR, a severe effect needing close monitoring (e.g., creatinine, urine output) to adjust dosing or hydration. Ototoxicity , hepatotoxicity , and cardiotoxicity are less common. Nephrotoxicity's frequency and severity align with amphotericin's membrane-binding mechanism, critical in fungal infections where prolonged use is typical, making A the priority to monitor for renal protection.
Question 5 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.
