Nursing Elites

1. A patient is prescribed medroxyprogesterone acetate (Provera) for the treatment of endometriosis. What key instruction should the nurse provide regarding the administration of this medication?

• A. Take the medication at the same time each day to maintain consistent hormone levels.
• B. Discontinue the medication if side effects occur.
• C. Take the medication with food to prevent gastrointestinal upset.
• D. Apply the medication once a week.

Correct answer: A

Rationale: The correct instruction for medroxyprogesterone acetate (Provera) is to take the medication at the same time each day to maintain consistent hormone levels and ensure its effectiveness. Choice B is incorrect because discontinuing the medication abruptly without consulting healthcare providers can be harmful. Choice C is incorrect as taking the medication with food is not necessary for this specific drug. Choice D is incorrect as medroxyprogesterone is typically taken orally, not applied topically.

2. During a follow-up visit, a patient being treated for latent tuberculosis mentions inconsistent drug intake. What should subsequent health education focus on?

• A. The importance of adhering to the treatment regimen to reduce adverse effects
• B. The necessity of consistently taking the prescribed drugs for TB cure
• C. Matching drug dosages carefully to signs and symptoms
• D. The consequence of nonadherence leading to antiretroviral use

Correct answer: B

Rationale: The correct answer is B because consistent intake of prescribed drugs is crucial for curing tuberculosis. By emphasizing the necessity of following the treatment plan, the patient is more likely to achieve a successful outcome. Choice A is incorrect because it focuses on the risk of adverse effects rather than the primary goal of TB cure. Choice C is incorrect as it does not address the issue of inconsistent drug intake. Choice D is also incorrect as it introduces a different treatment (antiretrovirals) not relevant to latent tuberculosis.

3. The nurse is caring for a client with an astrocytoma. The client asks, 'What do astrocytes do in the brain?' What is the nurse's best response?

• A. Astrocytes help to nourish and support neurons in the brain.
• B. Astrocytes are a type of neuron that transmit electrical signals.
• C. Astrocytes are involved in immune responses in the brain.
• D. Astrocytes help regulate blood flow in the brain.

Correct answer: A

Rationale: Astrocytes play a crucial role in supporting and nourishing neurons by providing metabolic support, maintaining the blood-brain barrier, and regulating the chemical environment of the brain. While astrocytes are essential for brain function, they are not neurons and do not transmit electrical signals (Choice B). Astrocytes are not primarily involved in immune responses in the brain (Choice C) or in regulating blood flow in the brain (Choice D), although they indirectly influence blood flow through their support functions.

4. In a postmenopausal woman, what condition can be prevented by administering estradiol (Estraderm)?

• A. Endometriosis
• B. Amenorrhea
• C. Osteoporosis
• D. Uterine cancer

Correct answer: C

Rationale: The correct answer is C: Osteoporosis. Estradiol, a form of estrogen, is used to prevent osteoporosis in postmenopausal women by maintaining bone density. Choice A, Endometriosis, is incorrect as estradiol is not used to prevent or treat this condition. Choice B, Amenorrhea, is not prevented by estradiol but rather may result from hormonal changes. Choice D, Uterine cancer, is not directly prevented by estradiol; in fact, long-term unopposed estrogen use can increase the risk of uterine cancer.

5. What therapeutic effect is expected from tamsulosin (Flomax) in a male patient with benign prostatic hyperplasia (BPH)?

• A. Relaxation of the muscles in the prostate and bladder neck, leading to improved urinary flow.
• B. Increase in urine flow and relief of urinary obstruction.
• C. Reduction in prostate size and improvement in urinary symptoms.
• D. Improvement in erectile function.

Correct answer: A

Rationale: The correct answer is A: 'Relaxation of the muscles in the prostate and bladder neck, leading to improved urinary flow.' Tamsulosin is an alpha-blocker that specifically targets alpha-1 receptors in the prostate and bladder neck, causing relaxation of smooth muscles. This relaxation results in improved urinary flow and reduced symptoms of BPH. Choice B is incorrect because while tamsulosin does improve urinary flow, it does not directly increase urine flow. Choice C is incorrect because tamsulosin does not reduce prostate size. Choice D is incorrect as tamsulosin does not have a primary effect on erectile function.
