Correct Answer: B

Rationale: The correct answer is B: Sandostatin. This drug is a somatostatin analog that can help manage HIV-related chronic severe diarrhea by reducing gastrointestinal secretions. Sandostatin works by inhibiting the release of various hormones and neurotransmitters in the gut, which can help control diarrhea in HIV patients. Rationale: A: Zithromax is an antibiotic that is not typically used to manage chronic severe diarrhea in HIV patients. C: Levaquin is also an antibiotic and not indicated for managing diarrhea in HIV patients. D: Biaxin is another antibiotic and not the appropriate choice for managing chronic severe diarrhea in HIV patients. In summary, Sandostatin is the correct choice as it specifically targets the underlying cause of diarrhea in HIV patients by reducing gastrointestinal secretions, whereas the other options are antibiotics that are not indicated for this purpose.

Correct Answer: A

Rationale: The correct initial action for the school nurse is to assess for signs and symptoms of anaphylaxis (Choice A). This is crucial as anaphylaxis is a severe allergic reaction that can be life-threatening and requires immediate intervention. Assessing for anaphylaxis symptoms such as difficulty breathing, swelling of the face or throat, and a rapid pulse helps the nurse quickly identify the severity of the situation. Administering OTC antihistamines (Choice C) or epinephrine (Choice D) should only be done after confirming the presence of anaphylaxis. Assessing for erythema and urticaria (Choice B) is important but not as immediate as assessing for signs of anaphylaxis in this scenario.

Correct Answer: C

Rationale: The correct answer is C: Impaired verbal communication. In ALS, motor neurons deteriorate leading to muscle weakness and atrophy, including those involved in speech production. This results in impaired verbal communication. Chronic confusion (A) is not a common manifestation of ALS. Impaired urinary elimination (B) and bowel incontinence (D) are not typically associated with ALS, as it primarily affects motor neurons, not autonomic functions.

Correct Answer: B

Rationale: The correct answer is B: Initiate high-flow oxygen therapy. Dyspnea in a patient with lung cancer can be caused by hypoxia due to compromised lung function. High-flow oxygen therapy can help improve oxygenation and alleviate dyspnea. Administering a bolus of normal saline (A) would not directly address the underlying cause of dyspnea. Administering high doses of opioids (C) may lead to respiratory depression and should be used cautiously in patients experiencing dyspnea. Administering bronchodilators and corticosteroids (D) may be appropriate for certain types of dyspnea, but in this case, addressing hypoxia with high-flow oxygen therapy is the most appropriate initial nursing action.

Correct Answer: B

Rationale: The correct answer is B: The patient has a history of hypertension. Hypertension is a risk factor for erectile dysfunction as it can lead to reduced blood flow to the penis, impacting the ability to achieve and maintain an erection. High blood pressure can damage blood vessels and affect the circulation necessary for an erection. Other choices are less likely to directly contribute to erectile dysfunction. A: UTI treatment is not typically associated with erectile dysfunction. C: Age alone is not a direct cause of erectile dysfunction, although it can increase the risk. D: While a sedentary lifestyle can impact overall health, it is less likely to directly cause erectile dysfunction compared to hypertension.
