A patient with psychologic disorder is being treated with a drug. Few months he is worried that he is constantly thirsty and urinates copiously frequently throughout the day and night. Which of the following drugs most likely cause inappropriate secretion of ADH?

Correct Answer: B

Rationale: The correct answer is B: Lithium. Lithium is known to cause nephrogenic diabetes insipidus, leading to inappropriate secretion of ADH. This results in excessive thirst and copious urination. Diazepam (A) does not affect ADH secretion. Haloperidol (C) and Phenytoin (D) are not associated with ADH dysregulation.

Correct Answer: B

Rationale: The correct answer is B: By lightly striking the fist at the costovertebral angle. This method is known as percussion and is used to assess for kidney tenderness or pain. Percussion helps to identify any abnormalities in the kidneys or surrounding structures. Auscultation (choice A) is used to listen for sounds, not assess for tenderness. Observing for signs of bleeding (choice C) and monitoring pressure dressing (choice D) are not appropriate methods for assessing kidney tenderness or pain.

Correct Answer: B

Rationale: The correct answer is B: Help flush the stones through the urinary tract. Increasing fluid intake can help dilute the urine, preventing stone formation and aiding in the passage of existing stones. Adequate hydration promotes frequent urination, which can help flush out the stones and reduce the risk of complications. Choices A, C, and D are incorrect. A: Concentrating the urine can actually exacerbate stone formation. C: Struvite crystals are not typically formed in nephrolithiasis. D: Breaking down stones requires medical intervention, not just increased fluid intake.

Correct Answer: C

Rationale: The correct answer is C because a history of intermittent catheterization increases the risk of urinary tract infections due to potential introduction of bacteria into the urinary system. This directly supports the diagnosis of a urinary tract infection. A: The wife's history is irrelevant unless the patient had direct contact or shared personal items with her. B: Prostate disease does not directly correlate with a urinary tract infection. D: Kidney stones are not directly related to urinary tract infections unless there was an associated infection during the stone removal.

Correct Answer: B

Rationale: The correct answer is B because demonstrating how to perform intermittent self-catheterization is within the scope of practice for an LPN/LVN. This task involves a specific skill set that can be taught and supervised by the LPN/LVN. It is essential for managing reflex urinary incontinence and maintaining bladder function. Choices A, C, and D are incorrect because teaching the patient bladder emptying by the Credé method (A) and discussing the side effects of bethanechol chloride (C) are tasks that require a higher level of nursing education and knowledge. Reinforcing the importance of proper handwashing (D) is a basic nursing task that can be performed by a nursing assistant or other unlicensed assistive personnel.
