Correct Answer: C

Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.

Correct Answer: A

Rationale: The correct order for abdominal assessment is inspection, auscultation, percussion, and palpation. Inspection allows the nurse to visually assess the abdomen for any abnormalities or distension. Auscultation follows to listen for bowel sounds and vascular sounds. Percussion helps to assess the density of underlying structures and detect any abnormal masses. Palpation is performed last to assess tenderness, organ size, and detect any masses. Choices B, C, and D have the steps in the incorrect order, making them the wrong choices.

Correct Answer: A

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. This step helps prevent obstruction in the tubing, maintaining proper urine flow and reducing the risk of infection. Changing the catheter every 72 hours is not recommended unless clinically indicated, as routine changes can increase the risk of introducing pathogens. Cleaning the perineal area with an antiseptic solution is essential for general hygiene but does not directly prevent catheter-related infections. Irrigating the catheter with normal saline every shift is not a standard practice and can introduce microorganisms into the urinary tract, increasing the risk of infection.

Correct Answer: B

Rationale: The correct answer is B: Affective. The caregiver's decision to postpone toilet training indicates a change in feelings or attitudes, which falls under the affective domain of learning. The affective domain relates to emotions, values, and attitudes. In this scenario, the caregiver's willingness to delay toilet training due to new information reflects a shift in attitude impacted by the educational session provided by the nurse. Choices A, C, and D are incorrect. The cognitive (choice A) domain involves intellectual skills and knowledge, the psychomotor (choice C) domain involves physical skills, and kinesthetic (choice D) is often used interchangeably with the psychomotor domain, which focuses on physical movement and coordination.

Correct Answer: B

Rationale: The correct answer is B: 'No two individuals perform hygiene in the same manner.' It is crucial to individualize a patient's care based on understanding the patient's unique hygiene practices and preferences. Choice A is incorrect because hygiene care should be tailored to the individual's needs and preferences, not seen as routine and expected for everyone. Choice C is incorrect as standardizing a patient's hygienic practices may not address their specific needs. Choice D is incorrect because understanding patient needs is essential during hygiene care to provide personalized and effective care.
