Correct Answer: C

Rationale: The correct answer is C: 10 to 15 g of a simple carbohydrate. This amount of carbohydrate is recommended for treating hypoglycemia in clients with diabetes to quickly raise blood glucose levels without causing hyperglycemia. Consuming too little carbohydrate may not effectively raise blood glucose levels, while consuming too much may lead to a rapid spike followed by a rebound hypoglycemia. Options A and B provide insufficient amounts of carbohydrate, while option D provides excessive carbohydrate, increasing the risk of hyperglycemia. Therefore, option C is the most appropriate choice for effectively treating hypoglycemia in this client.

Correct Answer: B

Rationale: The correct answer is B because encouraging the patient to do leg exercises within the limits of his traction promotes independence by maintaining muscle strength and mobility. This helps prevent muscle atrophy and promotes circulation. Choice A focuses on pain management but does not directly promote independence. Choice C provides assistance but does not actively involve the patient in self-care. Choice D is important for overall care but does not directly promote independence through active patient involvement.

Correct Answer: B

Rationale: The correct answer is B because involving the client and family in developing outcomes promotes patient-centered care and increases the likelihood of achieving successful outcomes. This approach fosters collaboration, shared decision-making, and empowers the client and family in their own care. It also helps to ensure that the outcomes align with the client's values, preferences, and goals. Choices A, C, and D are incorrect because focusing solely on nursing goals without considering the client's perspective may lead to a lack of engagement and poor outcomes. Discouraging input from other healthcare providers limits the interdisciplinary approach to care, and focusing on why the nurse believes the outcome is important neglects the client's role in the decision-making process.

Correct Answer: D

Rationale: The correct answer is D. Wearing cotton gloves, especially during sleep, helps reduce itching by preventing scratching, which can further irritate the skin. Cotton is a breathable fabric that reduces friction and irritation. A: Humidifying the environment may help in some cases, but it doesn't directly address the itching or maintaining skin integrity. B: Avoiding a skin lubricant is not recommended as it can help moisturize the skin and reduce itching. C: Bathing with a bar soap that contains lye can be harsh and drying, exacerbating the skin reaction.

Correct Answer: D

Rationale: The correct answer is D: Sigmoidoscopy. This procedure allows direct visualization of the lower colon and rectum, enabling the detection of colorectal cancer. Stool hematest (A) detects blood in the stool but does not confirm cancer. Abdominal CT (B) can show abnormalities but is not specific for colorectal cancer. CEA scan (C) measures a tumor marker but is not definitive for diagnosis. Sigmoidoscopy (D) is the gold standard for diagnosing colorectal cancer as it allows for direct visualization and tissue biopsy.
