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: B

Rationale: The correct answer is to apply a moisture-retentive dressing. This type of dressing promotes a moist wound environment, which is crucial for wound healing. Applying a heating pad can lead to tissue damage, while daily wound irrigation can disrupt the wound healing process. Applying an ice pack is not recommended for promoting wound healing in this scenario.

Correct Answer: B

Rationale: Increased heart rate is a common sign of fluid volume deficit (FVD) as the body compensates for decreased fluid levels. When a client is experiencing FVD, the body tries to maintain perfusion to vital organs by increasing the heart rate. This compensatory mechanism helps to improve cardiac output and maintain blood pressure. Choices A, C, and D are incorrect because in FVD, hematocrit may be increased due to hemoconcentration, blood pressure tends to decrease as a compensatory response to FVD, and respiratory rate is usually unaffected or may increase due to attempts to maintain oxygenation.

Correct Answer: B

Rationale: The correct answer is B: 'Wear shoes at all times.' This instruction is crucial for clients with diabetes as it helps protect the feet from potential injuries. Choice A of soaking feet in warm water daily can lead to skin issues and should be avoided. Cutting toenails in a rounded shape, as mentioned in choice C, can increase the risk of ingrown toenails. While inspecting the feet weekly, as in choice D, is important, wearing shoes at all times is a more preventative measure to avoid foot injuries in diabetic clients.

Correct Answer: B

Rationale: The correct answer is B because the surgeon should address the client's doubts before surgery. Informed consent requires that the client fully understands the procedure. Choice A is incorrect because reassuring the client of the surgeon's skill does not address the client's doubts about the need for surgery. Choice C is incorrect because telling the client surgery is necessary may not address their concerns and could violate the principle of autonomy. Choice D is incorrect as the immediate concern is addressing the client's doubts before surgery, not necessarily seeking a second opinion.
