Correct Answer is C
Explanation
A. Stridor: Stridor is a harsh, high-pitched inspiratory sound from upper-airway obstruction, often audible without a stethoscope and focused on inspiration.
B. Crackles: Crackles (rales) are intermittent, popping sounds usually from fluid in the alveoli and are not described as continuous high-pitched squeaks on exhalation.
C. Wheezes: Wheezes are continuous, musical, high-pitched sounds heard primarily on exhalation (though they can occur on both phases) and are typical in asthma due to narrowed airways.
D. Rhonchi: Rhonchi are low-pitched, snoring or gurgling sounds caused by larger-airway secretions and are not the high-pitched squeaks described.
Correct Answer is C
Explanation
A. Orthopnea: Orthopnea describes shortness of breath when lying flat, not the visible inward pulling of chest wall muscles.

C. Retractions: Retractions describe inward movement of intercostal or suprasternal tissues during inspiration and indicate increased work of breathing or respiratory distress.
