Correct Answer: A

Rationale: The appropriate initial action for the nurse is to examine the elbow. This step is crucial to assess the site of pain, identify any visible signs of injury or inflammation, and determine the cause of the discomfort. Administering pain medication (Choice B) should come after a thorough assessment. Applying a warm compress (Choice C) might provide temporary relief but does not address the underlying cause. Assessing the client's range of motion (Choice D) is important but would come after the initial examination to further evaluate the elbow joint.

Correct Answer: C

Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.

Correct Answer: D

Rationale: In this scenario, the nurse should instruct the client to take deep, rhythmic breaths as a nonpharmacological pain management technique. Deep, rhythmic breathing helps with relaxation and pain management, potentially reducing the perception of pain. Encouraging the client to apply a heating pad for 2 hours at a time (Choice A) is not recommended as prolonged heat application can lead to tissue damage and is not suitable for mild back pain. Applying an ice pack for 1 hour (Choice B) may not be appropriate for mild back pain as cold therapy is more commonly used for acute injuries. Removing distractions from the client's room (Choice C) may help create a more calming environment, but it does not directly address the client's pain.

Correct Answer: A

Rationale: During an acute asthma attack, one of the expected assessments by the nurse would be diffuse expiratory wheezing. This occurs due to narrowed airways and increased airflow velocity. Choice B, a loose productive cough, is not typically associated with an asthma attack. Choice C, no relief from inhaler, may indicate ineffective treatment but is not a direct assessment finding related to the physical examination. Choice D, fever and chills, are not typical symptoms of an asthma attack and would not be expected findings during the initial assessment of an acute asthma attack.

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.
