Rationale: For an adult, the correct method to straighten the ear canal during examination is to pull the pinna up and back. This maneuver aligns the ear canal for better visualization of the tympanic membrane and inner structures. Pulling down and back is appropriate for children under 3, while the other options do not correctly align the canal.

Rationale: The sense of taste is primarily mediated by the facial nerve (cranial nerve VII) and the glossopharyngeal nerve (cranial nerve IX). Evaluating sensory function, including taste, is the most appropriate action to assess the patient's complaint. Testing specific cranial nerves like the hypoglossal (XII) or spinal accessory (XI) is not directly related to taste.

Rationale: The absence of bowel sounds for one minute does not necessarily indicate a surgical emergency. Listening for another minute is appropriate to confirm the absence of sounds.

The other options provide situation, assessment, or background information but do not suggest a specific action.

Correct Answer: A

Rationale: The primary role of a registered nurse in a genitalia examination is inspection, visually assessing for abnormalities, lesions, or infections. Palpation may also be performed to check for tenderness or lumps, but auscultation and percussion are not typically used.
