Correct Answer: C

Rationale: Applying sequential compression devices is the appropriate intervention for a client at risk for developing deep vein thrombosis (DVT). This intervention helps prevent venous stasis by promoting circulation in the lower extremities, reducing the risk of DVT. Massaging the client's legs every 4 hours is contraindicated as it can dislodge a blood clot and increase the risk of embolism. Administering prophylactic antibiotics is not indicated for preventing DVT. Encouraging the client to remain on bed rest can contribute to venous stasis and increase the risk of developing DVT.

Correct Answer: C

Rationale: The correct answer is C: Teach the client pursed-lip breathing technique. Pursed-lip breathing helps clients with COPD improve oxygenation and reduce shortness of breath. Choice A is incorrect because deep breathing and coughing are not recommended every 4 hours for clients with COPD. Choice B is incorrect because a diet high in carbohydrates and low in protein is not specifically indicated for COPD. Choice D is incorrect because fluid restriction is not a standard intervention for COPD unless the client has comorbid conditions that necessitate it.

Correct Answer: B

Rationale: The correct instruction for a client taking digoxin is to notify their provider if they experience visual disturbances. Visual disturbances can be a sign of digoxin toxicity, and prompt notification to the healthcare provider is essential for timely intervention. Choice A is incorrect because digoxin should be taken on an empty stomach for better absorption. Choice C is incorrect because antacids can interfere with the absorption of digoxin. Choice D is incorrect because a heart rate less than 60/min is not a sole reason to avoid taking digoxin; rather, it is important to monitor the heart rate and consult with the healthcare provider if there are concerns.

Correct Answer: C

Rationale: The correct answer is C: 'Remain upright for at least 30 minutes after taking this medication.' This instruction is crucial when taking alendronate as it reduces the risk of esophagitis by preventing the medication from irritating the esophagus. Choice A is incorrect because alendronate should be taken in the morning, not at bedtime, to enhance absorption. Choice B is incorrect as alendronate should be taken on an empty stomach, preferably in the morning, with a full glass of water. Choice D is incorrect as there are no specific restrictions on taking alendronate with calcium-rich foods.

Correct Answer: A

Rationale: The correct action when digitally evacuating a fecal impaction is to insert a lubricated gloved finger and advance along the rectal wall. This technique helps prevent trauma and effectively dislodge the impacted stool. Choice B, applying lubricant and stimulating peristalsis, is incorrect as it does not directly address the evacuation of the impacted stool. Choice C, applying pressure to the abdomen, is inappropriate and may cause discomfort or harm to the client. Choice D, increasing fluid intake before the procedure, is not directly related to the immediate evacuation of the fecal impaction.
