A child with a serious fungal infection is receiving amphotericin B parenterally. Which of the following minerals will the patient most likely be required to receive?
- A. Chloride
- B. Magnesium
- C. Glucose
- D. Sodium
Correct Answer: B
Rationale: When a patient is receiving amphotericin B, which is known to cause renal toxicity, they are most likely to require magnesium supplementation. Amphotericin B can lead to renal loss of magnesium, potassium, and calcium. Magnesium is an essential mineral that plays a vital role in various physiological functions, and its levels need to be monitored and supplemented when necessary. Chloride, glucose, and sodium are not typically supplemented in the context of amphotericin B therapy for a serious fungal infection.

A patient is prescribed medroxyprogesterone acetate (Provera) for endometriosis. What should the nurse teach the patient about the proper use of this medication?
- A. Take the medication at the same time each day to maintain consistent hormone levels.
- B. Avoid prolonged sun exposure while taking this medication.
- C. Discontinue the medication if side effects occur.
- D. Apply the medication once a week.
Correct Answer: A
Rationale: The correct answer is to take the medication at the same time each day to maintain consistent hormone levels and effectiveness. Consistency in timing helps regulate the hormone levels in the body, ensuring the medication's optimal benefit. Choice B is incorrect as there is no specific need to avoid sun exposure with this medication. Choice C is incorrect because discontinuing the medication without consulting the healthcare provider may not be safe. Choice D is incorrect as medroxyprogesterone acetate is typically taken orally and not applied topically once a week.
A patient with a history of venous thromboembolism is prescribed hormone replacement therapy (HRT). What should the nurse discuss with the patient regarding the risks of HRT?
- A. HRT is associated with an increased risk of venous thromboembolism, so the patient should be aware of the signs and symptoms of blood clots.
- B. HRT can decrease the risk of osteoporosis, but the patient should also be aware of the increased risk of venous thromboembolism.
- C. HRT may increase the risk of breast cancer, so the patient should undergo regular breast exams.
- D. HRT can improve mood and energy levels, but it also carries a risk of cardiovascular events.
Correct Answer: A
Rationale: The correct answer is A. Hormone replacement therapy (HRT) is indeed associated with an increased risk of venous thromboembolism. Therefore, patients should be educated about the signs and symptoms of blood clots and advised to seek immediate medical attention if they occur. Choice B is incorrect because although HRT may decrease the risk of osteoporosis, the focus of concern in this case is the increased risk of venous thromboembolism. Choice C is incorrect as it mentions the risk of breast cancer, which is not the primary concern when discussing HRT with a patient with a history of venous thromboembolism. Choice D is also incorrect as it mentions cardiovascular events, which are not the main focus of risk associated with HRT in this scenario.
A patient is hospitalized due to nonadherence to an antitubercular drug treatment. Which of the following is most important for the nurse to do?
- A. Observe the patient taking the medications.
- B. Administer the medications parenterally.
- C. Instruct the family on the medication regimen.
- D. Count the number of tablets in the bottle daily.
Correct Answer: A
Rationale: In this scenario, the most crucial action for the nurse to take is to observe the patient taking the medications. This ensures that the patient is actually consuming the prescribed antitubercular drugs, addressing the issue of nonadherence directly. Administering the medications parenterally (intravenously or intramuscularly) is not necessary unless there are specific medical reasons requiring this route of administration. Instructing the family on the medication regimen is important for support but may not directly address the patient's nonadherence. Counting the number of tablets in the bottle daily is not as effective as directly observing the patient taking the medications to ensure compliance.
While planning care for an elderly patient, the nurse remembers that increased age is associated with:
- A. Increased T cell function
- B. Increased immune function
- C. Increased production of antibodies
- D. Increased levels of circulating autoantibodies
Correct Answer: D
Rationale: As individuals age, their immune function tends to decrease, making them more susceptible to infections and diseases. Additionally, increased age is associated with higher levels of circulating autoantibodies, which can lead to autoimmune conditions. Choice A is incorrect as aging is not typically associated with increased T cell function. Choice C is also incorrect as aging does not necessarily result in increased production of antibodies. Therefore, the correct answers are B (Decreased immune function) and D (Increased levels of circulating autoantibodies).
A patient is prescribed tadalafil (Cialis) for erectile dysfunction. What specific contraindication should the nurse discuss with the patient?
- A. History of hypertension
- B. Use of nitrates
- C. Use of antihypertensive medications
- D. History of peptic ulcer disease
Correct Answer: B
Rationale: The correct answer is B: 'Use of nitrates.' Tadalafil (Cialis) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and Cialis both cause vasodilation, which can lead to a dangerous drop in blood pressure when used together. Choices A, C, and D are incorrect because a history of hypertension, use of antihypertensive medications, and a history of peptic ulcer disease are not specific contraindications for tadalafil use.
