Correct Answer: A

Rationale: The correct answer is A: Etiology. Etiology in a nursing diagnosis refers to the cause or contributing factors that lead to the identified problem. In this case, the presence of a large scar over the left side of the face is the underlying cause of the disturbed self-esteem. It directly influences the client's self-perception and self-worth. The problem (B) is the disturbed self-esteem itself, not the scar. Defining characteristics (C) are the signs and symptoms that support the nursing diagnosis. Client need (D) is a broader concept that encompasses the overall needs of the client, whereas etiology specifically focuses on the cause of the problem.

Correct Answer: B

Rationale: The correct answer is B because the nurse should always prioritize communication with the patient, especially when the patient is alert and oriented. Speaking only to the patient's daughter could undermine the patient's autonomy and right to be involved in their care. It is important for the nurse to directly address the patient to gather accurate information and ensure patient-centered care. Making eye contact (A), leaning forward (C), and nodding periodically (D) are all appropriate communication techniques that show attentiveness and engagement with the patient, which are crucial in building rapport and trust.

Correct Answer: A

Rationale: Step 1: Assess the client's vital signs to confirm presence of fever. Step 2: Measure client's oral temperature to obtain accurate reading. Step 3: Document temperature and report findings to healthcare provider. Step 4: Initiate appropriate interventions based on temperature reading. Step 5: Reassess client's condition to evaluate effectiveness of interventions. Summary: Option A is correct as it directly addresses the cue of fever by confirming the temperature. Options B, C, and D are incorrect as they do not directly address the need to assess the client's temperature for accurate evaluation and intervention.

Correct Answer: D

Rationale: The correct answer is D because airborne pollens and molds are common triggers for allergic rhinitis. Understanding these triggers helps in avoiding exposure and managing symptoms. Choices A, B, and C are incorrect as they do not specifically relate to allergic rhinitis triggers, focusing instead on other forms of medication or topical applications. By understanding airborne triggers, the patient can take appropriate preventive measures.

Correct Answer: D

Rationale: The correct answer is D because assessing for localized ischemia involves evaluating multiple factors. A: Assessing color and temperature helps determine perfusion. B: Checking capillary refill assesses circulation. C: Evaluating pulse rate indicates cardiac output. Doing all of the above provides a comprehensive assessment of arterial flow and potential ischemia. Other choices are incorrect as they do not cover all aspects necessary for a thorough assessment.
