Correct Answer: C

Rationale: A cold, pale lower leg is cause for the most concern as it could indicate compromised blood circulation, potentially leading to serious complications like ischemia or thrombosis. Diminished bowel sounds, loss of appetite, and tachypnea are not directly related to the client's condition in atrial fibrillation and the heart rate discrepancy.

Correct Answer: A

Rationale: The correct action the nurse should prioritize when a client is placed in skeletal traction for a fractured femur is to ensure that the weights are freely hanging. This is crucial to maintain proper alignment of the bone and prevent complications. Placing pillows under the client's knees (Choice B) is not a priority in skeletal traction. Adjusting the weights to alleviate discomfort (Choice C) should not be done without proper orders from the healthcare provider. Ensuring that the traction ropes are free of knots (Choice D) is important but ensuring the weights hang freely is the priority to maintain traction effectiveness.

Correct Answer: B

Rationale: Two positive responses on the CAGE questionnaire strongly suggest alcohol dependence. Choice A is incorrect as the CAGE questionnaire specifically targets alcohol abuse. Choice C is incorrect because one positive response is not enough to indicate alcohol addiction. Choice D is incorrect because alcohol dependence can be suggested with two positive responses, not all four.

Correct Answer: A

Rationale: The correct answer is A: Weight-bearing exercise. Weight-bearing exercise helps build and maintain bone density, which is critical in preventing osteoporosis. Activities like aerobic exercises, stretching, and low-impact exercises such as swimming are beneficial for overall fitness but do not directly contribute to improving bone strength, making them less effective in preventing osteoporosis.

Correct Answer: D

Rationale: Diuretics are commonly used to decrease intraocular pressure in clients with glaucoma. They work by reducing the production of aqueous humor in the eye or by increasing its outflow. Anticholinergics (Choice A) are not typically used in the treatment of glaucoma and can even increase intraocular pressure. Beta blockers (Choice B) are also commonly used in glaucoma treatment as they reduce aqueous humor production. Alpha blockers (Choice C) are not the first-line treatment for glaucoma and are not as commonly used as diuretics or beta blockers.
