A client suspected of having colorectal cancer will require which diagnostic study to confirm the diagnosis?

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.

Correct Answer: D

Rationale: The correct answer is D because the absence of skin breakdown indicates that the turning schedule was effective in preventing pressure ulcers. Skin breakdown is a key indicator of pressure ulcer development, so its absence suggests that the patient's skin integrity was maintained. Choice A is incorrect because documentation alone does not guarantee successful prevention. Choice B is incorrect as redness on the heels can still indicate the early stages of pressure ulcers. Choice C is unrelated to skin integrity and pressure ulcer prevention.

Correct Answer: D

Rationale: The correct answer is D: Proper positioning. Proper positioning helps maintain joint alignment, prevents pressure ulcers, and reduces the risk of contractures by keeping the muscles in a neutral position. This is crucial in preventing complications associated with spasticity. A: Active exercise may exacerbate spasticity and lead to muscle fatigue, increasing the risk of contractures. B: Use of tilt board may not directly address the need for proper positioning to prevent contractures. C: Deep massage may provide temporary relief but does not address the underlying issue of maintaining proper positioning to prevent contractures.

Correct Answer: B

Rationale: The correct answer is B because the inability to move the affected leg post lumbar microdiskectomy could indicate a serious complication like nerve damage or blood clot. This would require immediate medical attention to prevent further complications. Incisional pain (A) is common and can be managed with pain medication. A two-inch area of bleeding on the dressing (C) is concerning but can be managed with proper wound care unless it is excessive. Muscle spasm (D) is also common postoperatively and can be managed with medications or physical therapy.

Correct Answer: B

Rationale: The correct answer is B because Toni's behavior of minimizing her visual problems, focusing on future goals, seeking information about job opportunities, and expressing desire for more children reflects coping mechanisms used to deal with the exacerbation of her illness. This behavior suggests that she is trying to maintain a sense of normalcy and control in the face of her health challenges. A: Inappropriate euphoria is excessive happiness or excitement, which is not evident in Toni's behavior. C: Remission phase typically involves a decrease in symptoms, which is not reflected in Toni's situation. D: Realistic for her current level of physical functioning does not explain her behavior as coping mechanisms.

Correct Answer: B

Rationale: Correct Answer: B (High fat diet) Rationale: 1. Ketogenic diet for seizures aims to produce ketones for brain energy, achieved through high fat intake. 2. High fat intake helps induce ketosis, which may help reduce seizures in some children. Incorrect Choices: A: High carbohydrate diet - Contradicts the purpose of a ketogenic diet. C: High protein diet - Excessive protein can hinder ketosis and is not the primary focus of a ketogenic diet. D: Low fat diet - Opposite of the high fat requirement for a ketogenic diet to induce ketosis.

Correct Answer: C

Rationale: The correct answer is C. This statement warrants clarification as donating blood does not put individuals at risk of getting HIV. Blood donation involves a sterile process that ensures safety. Choice A is correct as using condoms can help prevent the transmission of HIV. Choice B is incorrect because modern blood screening techniques have greatly reduced the risk of HIV transmission through blood transfusions. Choice D is also correct as sharing needles is a high-risk behavior for HIV transmission. In summary, only choice C is incorrect as donating blood does not pose a risk of acquiring HIV.

Correct Answer: A

Rationale: The correct answer is A because an Ileostomy involves diverting the small intestine to an opening in the abdominal wall, so the urine will not be affected. The pouch collects waste from the small intestine. Nasogastric tube (B) is not typically required for an Ileostomy. Laparoscope (C) is used for visualizing the abdomen, not the bowel. Drinking liquids (D) so soon after surgery can be risky and is not recommended.

Correct Answer: B

Rationale: The correct answer is B: Cerebral edema. Hypernatremia is an elevated sodium level in the blood, which can lead to osmotic shifts causing water to move out of cells, including brain cells. This can result in cerebral edema, potentially leading to neurological complications. Incorrect choices: A: Red blood cell crenation - This occurs in hypertonic solutions, not hypernatremia. C: Red blood cell hydrolysis - Hypernatremia doesn't directly cause red blood cell hydrolysis. D: Renal shutdown - Hypernatremia can stress the kidneys, but it doesn't typically lead to renal shutdown.
