Correct Answer: A

Rationale: Corrected Rationale: The nurse should instruct the client to use pursed-lip breathing during activities to help improve oxygenation. Pursed-lip breathing can keep the airways open longer, facilitating better oxygen exchange and making it easier to exhale carbon dioxide. Choice B is incorrect as physical activity, within the client's limitations, is beneficial for maintaining overall health. Choice C is incorrect as weight-bearing exercises are important for bone health but not directly related to improving oxygenation in COPD. Choice D is incorrect as using a humidifier while sleeping can help with moisture in the airways but does not directly impact oxygenation in COPD.

Correct Answer: C

Rationale: The correct answer is to auscultate before palpation when performing an abdominal assessment. This sequence is crucial to prevent altering bowel sounds. Starting with palpation (Choice A) can lead to false interpretations of bowel sounds due to stimulation of the intestines. Inspecting the abdomen after palpation (Choice B) can also potentially alter the assessment findings. Starting with percussion (Choice D) is not recommended as it should come after auscultation to further assess underlying structures.

Correct Answer: B

Rationale: The correct answer is B. Wearing slippers or shoes when out of bed is crucial for clients with diabetes as it helps prevent injuries to the feet, reducing the risk of infection. Choices A, C, and D are incorrect. Soaking feet in hot water daily can lead to dryness and skin damage, applying lotion between toes can create a moist environment promoting fungal growth, and cutting nails in a rounded shape can increase the risk of ingrown nails.

Correct Answer: C

Rationale: The correct answer is C. By reducing fluid intake 2 hours before bedtime, the client can prevent nighttime awakenings to urinate, which promotes better sleep. Napping during the day (choice A) may interfere with nighttime sleep. Drinking caffeine (choice B) can disrupt sleep patterns. Exercising right before bed (choice D) can actually stimulate the body and make it harder to fall asleep.

Correct Answer: C

Rationale: The correct intervention for a client with dysphagia is to have them sit upright for 1 hour after meals. This position helps facilitate swallowing and reduces the risk of aspiration, which is crucial in managing dysphagia. Encouraging the client to lie down after eating (Choice A) can increase the risk of aspiration. Offering liquids with meals (Choice B) may also increase the risk of aspiration as it can affect swallowing coordination. Providing the client with a straw for drinking (Choice D) is not recommended as straws can increase the risk of aspiration in individuals with dysphagia.
