Correct Answer: A

Rationale: An elevated white blood cell count (WBC 15,000/mm�) is a common indicator of infection as the body increases WBC production to fight off pathogens. In conditions like infections, inflammation, or stress, the WBC count can rise. The other options, hemoglobin, platelet count, and sodium levels, are not typically specific indicators of infection. Hemoglobin measures the oxygen-carrying capacity of red blood cells, platelet count assesses clotting ability, and sodium levels indicate electrolyte balance.

Correct Answer: B

Rationale: The most crucial action to prevent infection in a client with an indwelling urinary catheter is to ensure the catheter tubing is free of kinks. Kinks in the tubing can lead to urine retention or obstruction, increasing the risk of infection. Changing the catheter every 72 hours is not necessary if there are no signs of infection or other issues. Cleaning the perineal area with antiseptic solution daily is important for hygiene but not the most critical action to prevent infection related to the catheter. Irrigating the catheter with normal saline every shift is not a routine practice and may increase the risk of introducing pathogens into the urinary system.

Correct Answer: B

Rationale: Auscultating the abdomen before palpation is the correct action for the nurse to take in this scenario. This approach helps to assess bowel sounds accurately and prevents the alteration of bowel sounds that can occur due to palpation. By auscultating first, the nurse can gather important information about bowel function before proceeding with the palpation. Choice A is incorrect because deep palpation should be avoided initially, especially in a client reporting abdominal pain, as it may cause discomfort or potential harm. Choice C is incorrect as palpation should typically start away from the site of pain to prevent exacerbating discomfort. Choice D is incorrect because assessing bowel sounds with the bell of the stethoscope is not the initial step recommended when a client reports abdominal pain; auscultation should be performed with the diaphragm of the stethoscope first.

Correct Answer: A

Rationale: When a nurse experiences reluctance to interact with a manipulative client, it is essential to address these feelings constructively. Discussing the feeling of reluctance with an objective peer or supervisor allows the nurse to gain perspective, reflect on the situation, and develop appropriate strategies for patient care. This action promotes self-awareness, professional growth, and ensures that patient care is not compromised. Option B is incorrect because avoiding the client may not address the underlying issues and can impact the therapeutic relationship. Option C is inappropriate as confronting the client may escalate the situation and hinder effective communication. Option D is not the immediate action needed in this scenario, as it focuses on behavior modification rather than addressing the nurse's feelings of reluctance.

Correct Answer: B

Rationale: The correct sequence for obtaining a clean catch urine specimen involves first cleaning the meatus to prevent contamination, then initiating voiding to catch the midstream urine. This method ensures that the sample is as uncontaminated as possible, making choice B the correct sequence. Option A is incorrect as cleaning the meatus should be done before voiding. Option C is incorrect as it does not involve catching a midstream urine sample. Option D is incorrect as it suggests catching urine throughout the entire voiding process, which may lead to contamination.
