Correct Answer: B

Rationale: The correct answer is B: 'Wear shoes at all times.' Clients with diabetes are at a higher risk of foot complications due to poor circulation and nerve damage. Wearing shoes at all times helps protect their feet from injuries. Choice A is incorrect because toenails should be cut straight across to prevent ingrown toenails. Choice C is incorrect as soaking feet in hot water can lead to burns or skin damage, especially for those with diabetes who may have reduced sensation. Choice D is incorrect because applying lotion between the toes can create a moist environment, increasing the risk of fungal infections.

Correct Answer: B

Rationale: Nausea is a common sign indicating that the client is not tolerating enteral feedings well. It can be a result of various issues such as feeding intolerance, infection, or other underlying conditions. Nausea should be promptly addressed to prevent further complications. Increased bowel sounds (Choice A) are not typically indicative of feeding intolerance. Elevated blood pressure (Choice C) and fever (Choice D) are generally not directly related to enteral feeding intolerance unless there are specific underlying conditions contributing to them.

Correct Answer: B

Rationale: The correct answer is B: 'Use pursed-lip breathing during activities.' Pursed-lip breathing improves oxygenation by keeping airways open longer, facilitating better exhalation of carbon dioxide. Choice A is incorrect because avoiding physical activity can lead to deconditioning and worsen oxygenation. Choice C is irrelevant to improving oxygenation in COPD. Choice D is not directly related to improving oxygenation in COPD; weight-bearing exercises are important for bone health but not for oxygenation.

Correct Answer: B

Rationale: The correct answer is 'Increased hematocrit.' In fluid volume deficit (FVD), there is a decrease in the amount of fluid in the blood vessels, leading to hemoconcentration. This results in an increase in hematocrit levels. Choices A, C, and D are incorrect because a decrease in hematocrit, decrease in white blood cell count, and an increase in red blood cell count are not typically seen in fluid volume deficit.

Correct Answer: B

Rationale: The correct answer is B: 'Use a special mattress for the client.' Using a special mattress reduces pressure on bony prominences and helps prevent pressure injuries. Repositioning the client every 4 hours (choice A) is important but using a special mattress is more effective. Keeping the client on bedrest (choice C) can increase the risk of pressure injuries due to prolonged immobility. Encouraging the client to remain in one position (choice D) is incorrect as it can lead to pressure injuries by exerting pressure on the same areas for an extended period.
