Correct Answer: B

Rationale: The correct instruction when using a metered-dose inhaler (MDI) is to shake the inhaler vigorously before use. Shaking the inhaler ensures proper mixing of the medication, which is crucial for effective delivery of the medication into the lungs. Inhaling for a specific duration, holding the inhaler at a certain distance from the mouth, or holding the breath after inhalation are not as critical as ensuring proper mixing of the medication by shaking the inhaler.

Correct Answer: B

Rationale: Frequent urge suppression can lead to constipation, especially postoperatively. Suppressing the urge to defecate can disrupt the normal bowel movement pattern and lead to constipation. Choices A, C, and D are behaviors that generally help prevent constipation rather than increase the risk. Increased physical activity, adequate sleep, and increased fluid intake promote bowel regularity and reduce the risk of constipation.

Correct Answer: C

Rationale: The correct answer is C: 'Take prescribed antihypertensive medications daily.' When providing discharge teaching to a client with hypertension, one of the key instructions is to ensure the consistent intake of prescribed antihypertensive medications. This is crucial for controlling blood pressure levels and reducing the risk of complications associated with hypertension. Choices A, B, and D are incorrect because reducing sodium intake, avoiding foods high in potassium, and limiting fluid intake are important dietary modifications for various health conditions, but they are not the priority when it comes to managing hypertension. The primary focus should be on medication adherence to effectively manage hypertension.

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: Increasing fiber intake is the appropriate intervention to include in the plan of care for a client with chronic constipation due to immobility. Fiber helps add bulk to the stool, making it easier to pass, thereby preventing constipation. Encouraging the client to walk daily (choice B) is also beneficial as it promotes mobility and can help alleviate constipation associated with immobility. Using a stool softener as needed (choice C) and using a laxative daily (choice D) are not the first-line interventions for managing constipation related to immobility. Stool softeners and laxatives should be used judiciously and under healthcare provider guidance.
