When the nurse is performing a genital examination on a male patient, the patient has an erection. The nurse’s most appropriate action or response is to:

Correct Answer: D

Rationale: The correct answer is D. This is the most appropriate action because it acknowledges the patient's normal physiological response and reassures him. It helps maintain professionalism and respect for the patient's dignity. Choice A could potentially embarrass the patient further. Choice B may ignore the patient's discomfort. Choice C abruptly halts the examination without addressing the situation. Overall, choice D is the most respectful and professional response in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Nitrofurantoin. Nitrofurantoin is contraindicated in the third trimester of pregnancy due to potential risk of hemolytic anemia in the fetus. It can also cross the placenta and reach the fetal bloodstream. Amoxicillin (B) and Cephalexin (D) are safe for use in pregnancy. Gentamycin (C) is generally not recommended during pregnancy due to potential risk of ototoxicity and nephrotoxicity but is not specifically harmful to the fetus.

Correct Answer: C

Rationale: Rationale: 1. Correct Answer (C - Sulfonamides): Sulfonamides inhibit folate synthesis in bacteria. Drinking water helps prevent crystalluria and kidney stone formation. 2. Incorrect Choices: A. Vancomycin - Acts on cell wall synthesis, not folate synthesis. B. Linezolid - Inhibits protein synthesis, not folate synthesis. D. Penicillin - Inhibits cell wall synthesis, not folate synthesis.

Correct Answer: B

Rationale: Answer B, Amphotericin B, is the most appropriate choice for treating aspergillosis due to its broad-spectrum antifungal activity, especially against Aspergillus species. It is often used for severe or systemic infections when other options are ineffective. Terbinafine (A) is more commonly used for dermatophyte infections, while Flucytosine (C) is typically used for certain yeast infections. Itraconazole (D) may be effective against some Aspergillus strains but is generally considered less effective than Amphotericin B for severe cases.

Correct Answer: B

Rationale: The correct answer is B: Meningeal tuberculosis. Corticosteroids are contraindicated in meningeal tuberculosis because they can suppress the immune response, leading to increased bacterial growth and dissemination in the central nervous system. For miliary, intestinal, and renal tuberculosis, corticosteroids can be beneficial in reducing inflammation and improving outcomes.
