Correct Answer: C

Rationale: The correct answer is C because anesthetics used during surgery can decrease bladder contractility, leading to urinary retention. By inserting an indwelling catheter, the nurse ensures proper drainage of urine and prevents bladder distention. This helps to maintain the patient's comfort and prevent complications such as urinary retention and potential bladder injury. Choice A is incorrect because inserting a catheter is not primarily to prevent uncontrollable voiding during surgery. Choice B is incorrect as local trauma does not promote excessive urine incontinence necessitating catheterization. Choice D is incorrect because the primary purpose of catheter insertion is not to prevent interruption of the procedure by bathroom breaks.

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: C

Rationale: The correct answer is C: Increase the patient's oral fluid intake. This is because severe diarrhea can lead to dehydration, which can be dangerous for patients with HIV infection. By increasing oral fluid intake, the patient can stay hydrated and prevent further complications. Administering antidiarrheal medications on a scheduled basis (Choice A) may provide temporary relief but does not address the underlying issue of dehydration. Encouraging the patient to eat balanced meals (Choice B) and increase activity level (Choice D) may be important for overall health but do not directly address the immediate concern of dehydration caused by severe diarrhea.

Correct Answer: D

Rationale: The correct answer is D: The patient has been infected with HIV. Antibodies to the AIDS virus in the blood indicate a past or current infection with HIV. This is because the body produces antibodies in response to the presence of the virus. A: The patient is immune to HIV is incorrect because antibodies indicate exposure, not immunity. B: The patient's immune system is intact is incorrect because the presence of antibodies does not necessarily reflect the overall functionality of the immune system. C: The patient has AIDS-related complications is incorrect because the presence of antibodies does not directly indicate the presence of AIDS-related complications.

Correct Answer: A

Rationale: The correct answer is A: Test the patient's hearing promptly. This is because before dispensing hearing aids, it is crucial to accurately assess the patient's hearing ability. Testing the patient's hearing promptly allows the healthcare professional to determine the type and degree of hearing loss, which is essential for selecting the appropriate hearing aids. Performing an otoscopy (choice B) may be part of the assessment but does not provide information on hearing ability. Measuring the width of the patient's ear canal (choice C) is not necessary for dispensing hearing aids. Referring the patient to his primary care physician (choice D) may delay the process of obtaining hearing aids and is not directly related to the responsibility of the health professional dispensing hearing aids.
