Correct Answer: B

Rationale: Frequent urge suppression can lead to constipation, especially postoperatively. Suppressing the urge to defecate can disrupt normal bowel movements and result in constipation. Increased physical activity, increased fiber intake, and adequate fluid intake are measures that typically help prevent constipation by promoting bowel regularity and preventing stool hardening. Therefore, choices A, C, and D are not behaviors that increase the client's risk for constipation.

Correct Answer: B

Rationale: Bowel inflammation can reduce the absorption of oral medications, leading to decreased effectiveness. In this case, the decrease in the effectiveness of the arthritis medication could be attributed to impaired absorption due to bowel inflammation. Choices A, C, and D are incorrect because increased activity level, long-term use of the medication, and history of dehydration are not directly associated with a decrease in medication effectiveness related to absorption issues.

Correct Answer: C

Rationale: The correct answer is to auscultate before palpation. This ensures that bowel sounds are not altered by physical manipulation. Inspecting the abdomen is a valid step but not the first. Percussing and palpating should come after auscultation to prevent altering bowel sounds or causing discomfort to the client.

Correct Answer: B

Rationale: The correct answer is to 'Use sequential compression devices.' Sequential compression devices help prevent DVT by promoting venous return, reducing stasis in the veins, and preventing blood clot formation. Resting in bed for long periods (Choice A) can actually increase the risk of DVT due to decreased mobility. Avoiding leg exercises (Choice C) is also not recommended as mobilization and exercises can help prevent blood clots. Keeping legs crossed (Choice D) can impede blood flow and is not advisable in reducing the risk of DVT.

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.
