Nursing Elites

1. A patient is being treated for a severe fungal infection with amphotericin B. What is the expected length of treatment for this patient?

• A. 1 to 2 weeks
• B. 3 to 6 weeks
• C. 4 to 12 weeks
• D. 15 to 18 weeks

Correct answer: C

Rationale: The correct answer is C: '4 to 12 weeks.' Amphotericin B treatment duration for severe fungal infections typically ranges from 4 to 12 weeks. This extended period is necessary to ensure complete eradication of the fungal infection and prevent relapse. Choices A, B, and D provide durations that are either too short or too long for treating severe fungal infections effectively, making them incorrect.

2. The nurse is closely following a patient who began treatment with testosterone several months earlier. When assessing the patient for potential adverse effects of treatment, the nurse should prioritize which of the following assessments?

• A. Skin inspection for developing lesions
• B. Lung function testing
• C. Assessment of serum calcium levels
• D. Assessment of arterial blood gases

Correct answer: C

Rationale: In patients receiving testosterone therapy, the nurse should prioritize assessing serum calcium levels. Testosterone therapy can lead to hypercalcemia, making the evaluation of serum calcium levels crucial. Skin inspection for developing lesions, lung function testing, and arterial blood gas assessment are not the priority assessments for potential adverse effects of testosterone therapy. Skin inspection may be relevant for dermatological side effects, lung function testing and arterial blood gas assessment are not directly related to the common side effects of testosterone therapy.

3. What causes the appearance of a barrel chest in clients with emphysema?

• A. Peripheral edema
• B. Bacterial infections in the lungs
• C. Air trapping in the alveoli
• D. Muscle atrophy of the diaphragm

Correct answer: C

Rationale: The correct answer is C: Air trapping in the alveoli. A barrel chest in emphysema results from the hyperinflation of the lungs due to air trapping in the alveoli. This leads to increased anteroposterior diameter of the chest. Choices A, B, and D are incorrect. Peripheral edema is swelling caused by fluid retention in tissues, not associated with a barrel chest in emphysema. Bacterial infections in the lungs can lead to conditions like pneumonia but do not directly cause a barrel chest. Muscle atrophy of the diaphragm could affect breathing mechanics but is not specifically linked to the development of a barrel chest in emphysema.

4. A patient is prescribed sildenafil (Viagra) for erectile dysfunction. What critical contraindication should the nurse review with the patient?

• A. Use of nitrates
• B. Use of antihypertensive medications
• C. History of hypertension
• D. History of peptic ulcer disease

Correct answer: A

Rationale: The correct answer is A: Use of nitrates. Sildenafil (Viagra) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and sildenafil both cause vasodilation, which can lead to a dangerous drop in blood pressure. Choice B (Use of antihypertensive medications) is incorrect because antihypertensive medications are not a critical contraindication for sildenafil use. Choice C (History of hypertension) is incorrect as it is not a contraindication for sildenafil; in fact, sildenafil is sometimes used in patients with hypertension. Choice D (History of peptic ulcer disease) is also incorrect as it is not a critical contraindication for sildenafil use.

5. A patient has been diagnosed with cytomegalovirus (CMV). Which of the following drugs would be ineffective in the treatment of this disease?

• A. Ribavirin (Rebetol)
• B. Ganciclovir (Cytovene) IV
• C. Foscarnet (Foscavir) IV
• D. Valganciclovir hydrochloride (Valcyte)

Correct answer: A

Rationale: The correct answer is A, Ribavirin (Rebetol). Ribavirin is not effective against CMV. Choice B, Ganciclovir (Cytovene) IV, is a common treatment for CMV as it inhibits viral DNA synthesis. Choice C, Foscarnet (Foscavir) IV, is also used for CMV infections by blocking viral DNA polymerase. Choice D, Valganciclovir hydrochloride (Valcyte), is a prodrug of Ganciclovir and is effective against CMV. Therefore, Ribavirin is the drug that would be ineffective in treating CMV.
