Correct Answer: C

Rationale: Cough with bloody sputum is a hallmark symptom of tuberculosis and is highly concerning as it indicates active disease. Hemoptysis (coughing up blood) is associated with tuberculosis infection in the lungs. While night sweats and weight loss are common symptoms of tuberculosis, they are less specific than coughing with bloody sputum. Fatigue is a nonspecific symptom that can be present in various conditions and is not specific to tuberculosis.

Correct Answer: B

Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.

Correct Answer: A

Rationale: To maintain the patency of a nasogastric (NG) tube, it is essential to flush the tube with 30 ml of water before and after medication administration. This action helps ensure that the tube remains open and free from blockages. Flushing the tube prevents any medication residue from causing blockages, maintaining its patency. Choice B is incorrect because administering medication with food does not relate to maintaining tube patency. Choice C is incorrect as verifying tube placement by aspirating stomach contents is related to confirming correct tube placement, not maintaining patency. Choice D is also incorrect because diluting the medication with normal saline is not primarily aimed at maintaining the tube's patency.

Correct Answer: D

Rationale: The priority action for the nurse is to address the client's immediate physiological need for comfort and pain relief during the dressing change. Administering pain medication 45 minutes before the procedure can help alleviate the pain experienced by the client. Encouraging relaxation techniques (choice A) is beneficial but may not provide sufficient pain relief during the dressing change. Educating about the importance of pain management (choice B) is relevant but does not address the immediate need for pain relief. Assisting the client to a comfortable position (choice C) is helpful but does not directly address the client's pain concern during the dressing change. Administering pain medication is the most direct and effective intervention to ensure optimal client comfort and compliance with necessary procedures.

Correct Answer: C

Rationale: The correct answer is C. Telangiectatic nevi, often referred to as 'stork bites,' are common birthmarks in infants and are considered normal. These birthmarks usually fade and disappear as the child grows older. Choices A, B, and D are incorrect because Mongolian spots are bluish-gray birthmarks commonly found in darker-skinned infants, port wine stains are vascular birthmarks that typically do not disappear, and surgical removal is not recommended for telangiectatic nevi as they usually resolve on their own.
