A mother brings her 2-month-old daughter in for an examination and says, "My daughter rolled over against the wall, and now I have noticed that she has this spot that is soft on the top of her head. Is something terribly wrong?" How should the nurse respond?

A. Is impaired in a patient with cataracts: Cataracts primarily cause lens opacity, leading to blurry vision and reduced acuity. They do not directly affect extraocular muscle function, which is controlled by cranial nerves rather than the lens.

B. Is always decreased in the older adult: Aging can cause minor changes in eye movement speed and coordination, but significant impairment is not inevitable. Extraocular muscle function remains intact unless affected by neurological conditions such as cranial nerve palsy.

C. Is stimulated by cranial nerves (CNS) I and II: Cranial nerve I (olfactory) is responsible for smell, and cranial nerve II (optic) transmits visual signals to the brain. Neither nerve controls eye movement, which is instead governed by different cranial nerves.

D. Is stimulated by cranial nerves III, IV, and VI: The oculomotor (III), trochlear (IV), and abducens (VI) nerves control extraocular muscle movement. They coordinate eye positioning, alignment, and smooth tracking, ensuring proper function of the visual system.

A. Bronchophony: Bronchophony is an increase in clarity of spoken sounds when auscultating the lungs, typically indicating lung consolidation or pathology. It is not an adventitious sound associated with airflow through narrowed bronchioles.

B. Wheezes: Wheezes are high-pitched, musical sounds that occur when air passes through narrowed or obstructed airways, such as in cases of severe asthma. They are often heard during expiration and indicate bronchoconstriction or inflammation in the airways. This is the correct answer for the scenario presented.

C. Bronchial sounds: Bronchial sounds are normal breath sounds typically heard over the trachea and major bronchi. They are characterized by a higher pitch and a hollow quality. They are not classified as adventitious sounds and are not indicative of asthma.

D. Whispered pectoriloquy: Whispered pectoriloquy is a clinical finding where whispered sounds are heard more clearly over areas of lung consolidation. Like bronchophony, it does not represent an adventitious sound caused by airflow through narrowed bronchioles and is more indicative of lung pathology.
