Correct Answer: C

Rationale: The Apgar score is based on five components: heart rate, respiratory effort, muscle tone, reflex irritability, and color. In this case, the infant has a heart rate over 100 (2 points), is crying (2 points indicating good respiratory effort), resists the catheter (2 points for good reflex irritability), but has acrocyanosis (partial point deduction of 1). Thus, the Apgar score at one minute after birth would be 8. Choice A is incorrect as the given signs indicate a higher score. Choice B is incorrect as the signs described support a score above 6. Choice D is incorrect as it represents a perfect score which is not the case here due to acrocyanosis.

Correct Answer: C

Rationale: A dark purple stoma may indicate compromised blood flow to the stoma, which is an emergency. Immediate notification of the healthcare provider is necessary to prevent further complications. Simply documenting and monitoring the finding (Choice A) could lead to delays in addressing a potentially serious issue. Applying warm compresses to the stoma (Choice B) may not address the underlying cause of the dark purple color. Encouraging the client to ambulate (Choice D) is not the priority when a compromised blood flow to the stoma is suspected.

Correct Answer: D

Rationale: Increasing fruits and vegetables in the diet is more beneficial in reducing cancer risk due to their high levels of antioxidants and fiber, which help protect against cancer. While exercise is important for overall health, in this context, focusing on fruits and vegetables is more relevant to reducing cancer risk than exercise alone. Providing information about cancer warning signs is not directly addressing the client's dietary choice. While Vitamin D is essential for various health aspects, the primary focus here should be on a diet rich in fruits and vegetables for cancer risk reduction.

Correct Answer: C

Rationale: The correct answer is C: Serum Creatinine. Serum creatinine is a key indicator of kidney function. Reviewing this value is crucial as it helps assess the client's risk for nephrotoxicity before administering the antibiotic. Elevated serum creatinine levels can indicate impaired kidney function, which would increase the risk of nephrotoxicity. Choices A, B, and D are not as directly related to kidney function and nephrotoxicity. Hemoglobin and hematocrit levels assess for anemia, serum calcium levels monitor calcium balance, and WBC count evaluates for infections. While these values are important for overall patient assessment, they are not as specific to assessing nephrotoxicity risk as serum creatinine.

Correct Answer: C

Rationale: The correct answer is C. In 90-90 traction, the weights should hang freely and not touch the foot of the bed to maintain proper traction and bone alignment. Option A is not necessarily a concern as bowel movements can be influenced by various factors, including diet changes and pain medication. Option B indicates good caregiver involvement, promoting comfort and preventing complications. Option D demonstrates neurovascular function, which is a positive finding. Therefore, the weights touching the foot of the bed is the finding that requires immediate attention to ensure the effectiveness of the traction.
