Correct Answer: C

Rationale: Keeping conversations short is the most appropriate intervention to promote comfort for a client with pneumonia. Pneumonia can be physically exhausting, and limiting the length of conversations helps conserve the client's energy. Encouraging visits from family and friends (Choice B) may be emotionally supportive but might not directly promote comfort in the context of conserving energy during recovery. Increasing oral fluid intake (Choice A) is important for hydration but may not directly address the client's comfort. Monitoring vital signs frequently (Choice D) is essential for assessing the client's condition but does not directly promote comfort.

Correct Answer: A

Rationale: The correct answer is A because wearing a mask in public can help prevent the spread of TB to others. Choice B is incorrect as taking medication as prescribed helps in treating the infection within the individual but does not directly prevent spreading it to others. Choice C is important for respiratory hygiene but may not be sufficient to prevent transmission. Choice D, isolation until treatment is complete, is crucial for preventing the spread but is not specifically about understanding transmission.

Correct Answer: D

Rationale: The correct answer is to instruct the client to increase protein intake. This is appropriate because increasing protein intake can help maintain muscle mass and strength in clients with COPD. Option A, 'Drink carbonated beverages,' is incorrect as carbonated beverages can exacerbate COPD symptoms. Option B, 'Decrease fiber intake,' is also incorrect as fiber is important for digestion and should not be decreased unless specifically advised by a healthcare provider. Option C, 'Use bronchodilators after meals,' is incorrect because bronchodilators are typically used before meals to help open the airways for better breathing, not after meals.

Correct Answer: D

Rationale: The correct answer is D: Altered patterns of urinary elimination related to nocturia. Nocturia increases the risk of falls in elderly clients due to frequent nighttime trips to the bathroom. Choice A is incorrect because while decreased vision can contribute to falls, nocturia poses a more direct risk. Choice B is incorrect as fatigue may affect mobility but is not as directly linked to falls as nocturia. Choice C is incorrect as impaired gas exchange is not typically associated with an increased risk of falls.

Correct Answer: B

Rationale: When administering enteral feeding through a jejunostomy tube, the nurse should administer the formula continuously. Continuous feeding is essential for optimal nutrient absorption and to prevent complications. Administering the formula every four to six hours, in a bolus, or every hour may lead to inadequate nutrition, improper absorption, and an increased risk of complications such as aspiration or dumping syndrome, making these choices incorrect.
