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: 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: 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: D

Rationale: Correct. Loss of hope is a significant psychosocial aspect that healthcare professionals should assess for in patients who are immobile. Immobility can lead to feelings of hopelessness and depression, impacting the patient's mental well-being. Assessing for loss of hope allows healthcare professionals to provide appropriate support and interventions to address the patient's emotional needs. Choices A, B, and C are incorrect because they primarily relate to physical changes (bone mass, strength, weight) rather than the psychosocial aspect of hope.

Correct Answer: B

Rationale: The correct technique for IV catheter insertion involves inserting the needle at a 10 to 30-degree angle with the bevel up. This angle facilitates proper vein puncture, reduces the risk of complications, and minimizes trauma to the vein. Choice A is incorrect because threading the needle into the vein at an angle of 10 to 30 degrees with the bevel up is the correct technique, not threading it all the way into the vein. Choice C is incorrect because applying pressure 1.2 inches below the insertion site before removing the needle is not a standard step in IV catheter insertion. Choice D is incorrect because selecting the antecubital fossa vein solely based on its size and accessibility may not be the most appropriate criterion; vein selection should also consider factors like vein condition and patient comfort.
