Correct Answer: C

Rationale: Rationale: 1. Abdominal injection sites have a higher blood supply, leading to faster absorption. 2. Insulin absorption is faster in areas with more blood vessels. 3. Rapid absorption at the abdomen results in quicker onset of action. 4. Other sites may have slower absorption due to less blood flow. Summary: A: Incorrect. Absorption is faster at abdominal sites due to increased blood flow. B: Incorrect. Absorption varies based on injection site blood supply. C: Correct. Abdominal injection sites have rapid insulin absorption. D: Incorrect. Insulin absorption is consistent based on blood flow at injection sites.

Correct Answer: A

Rationale: The correct answer is A: Denial. The client's refusal to accept the diagnosis of diabetes mellitus, stating that no one in their family has had it, indicates denial as a coping mechanism. Denial is a defense mechanism where individuals refuse to acknowledge unpleasant realities. In this case, the client is rejecting the diagnosis to avoid facing the reality of having a chronic condition. The other choices (B: Anger, C: Withdrawal, D: Resolution) do not fit the client's response in this scenario. Anger involves expressing frustration or hostility, withdrawal is avoiding the situation, and resolution is accepting and dealing with the issue.

Correct Answer: C

Rationale: The correct answer is C: 5 years. In ALS, 50% of patients have a life expectancy of around 3-5 years from the time of diagnosis. This is due to the progressive nature of the disease, leading to rapid deterioration of motor neurons and muscle function. Choice A (3 years) is too specific and may not apply to exactly 50% of patients. Choice B (10 years) and D (20 years) are too optimistic and do not align with the typical prognosis of ALS, where the majority of patients have a shorter life expectancy. Therefore, based on the average survival rates and disease progression, choice C is the most accurate representation of the normal life expectancy for 50% of ALS patients.

Correct Answer: A

Rationale: The correct answer is A: circulating nurse. The circulating nurse is responsible for maintaining cleanliness, ensuring proper temperature, humidity, and lighting in the operating room. They coordinate activities, manage supplies, and ensure a safe environment for the surgical team. The scrub nurse assists the surgeon with instruments and supplies, not environmental conditions. The surgeon's main focus is on performing the surgery, not environmental management. The anesthesiologist is responsible for administering anesthesia and monitoring the patient's vital signs, not the operating room environment.

Correct Answer: B

Rationale: The correct answer is B: Use two people to assist the patient. This is the safest option as it provides optimal support and stability for the patient during their first postoperative ambulation. Two people can help prevent falls, ensure proper body mechanics, and offer immediate assistance if needed. Using one person (choice A) may not provide enough support. Encouraging the patient to "dangle" (choice C) may increase the risk of orthostatic hypotension. Giving a narcotic before ambulation (choice D) can impair the patient's balance and coordination, increasing the risk of falls.
