A nurse is reinforcing discharge teaching with a client following an episode of status
asthmaticus. The client has a prescription for two inhalations from an albuterol metered-dose inhaler. Which of the following statements by the client indicates an understanding of the
teaching?

A. Inspiratory stridor - This is associated with upper airway obstruction and is not indicative of a pneumothorax.

B. Expiratory wheeze - Wheezing is commonly associated with lower airway conditions such as asthma or chronic obstructive pulmonary disease (COPD), not pneumothorax.

C. Coarse crackles - Coarse crackles are typically heard in conditions such as pneumonia or pulmonary edema, not pneumothorax.

D. Absence of breath sounds - This is a key manifestation of a pneumothorax. The air in the pleural space can prevent the lung from fully expanding, leading to the absence of breath sounds on the affected side.

a. C-reactive protein: This is a marker of inflammation and is not specific to renal function. It is more commonly used to assess inflammation in various conditions.

b. Serum creatinine: Elevated levels of serum creatinine are indicative of impaired renal

function. Creatinine is a waste product that is normally filtered by the kidneys. Increased levels suggest decreased renal filtration.

c. Antinuclear antibody: This test is used to diagnose autoimmune diseases like SLE but does not directly measure renal function.

d. Erythrocyte sedimentation rate: This is a nonspecific marker of inflammation and is not directly related to renal function.
