Correct Answer: B

Rationale: The correct answer is B. Showing interest by occasional head nodding conveys warmth as it demonstrates active listening and engagement with the patient. This non-verbal cue can make the patient feel heard and understood. Choice A is incorrect as avoiding distracting actions like hand gestures may come off as cold or disinterested. Choice C leaning forward at a 45-degree angle can be perceived as invading the patient's personal space rather than conveying warmth. Choice D, placing arms across the chest to prevent fidgeting, can be interpreted as defensive or closed-off, which does not communicate warmth to the patient.

Correct Answer: B

Rationale: Step 1: Disturbed auditory perception means there is a deficit in the ability to receive/process auditory information. Step 2: Speaking slowly and distinctly helps the patient better understand and process the information. Step 3: Shouting may distort the sound and further confuse the patient. Step 4: Other options (A, C, D) address different sensory deficits and are not directly related to disturbed auditory perception.

Correct Answer: A

Rationale: The correct answer is A: Severe dyspnea. In a tension pneumothorax, air accumulates in the pleural space, increasing pressure in the chest cavity, leading to severe dyspnea due to impaired lung expansion. Extreme agitation (B) is not a typical finding. Tracheal deviation (C) is seen in tension pneumothorax, not always present. Progressive cyanosis (D) may occur but is not as specific as severe dyspnea.

Correct Answer: C

Rationale: The correct answer is C because it addresses the affective aspect of learning effective communication, which involves emotions, attitudes, and beliefs. Positive communication strategies can enhance confidence, leading to more effective interactions. Choice A focuses on technical aspects, choice B relates to nonverbal communication, and choice D emphasizes behavioral skills, but they do not directly address the emotional component of learning communication strategies.
