A nurse is reviewing the morning laboratory results of electrolytes for four clients who are receiving digoxin. Which of the following clients should the nurse identify as being at risk for developing digoxin toxicity?

Rationale for A: Taking enteric-coated pills with meals is generally acceptable as food does not affect the integrity of the enteric coating. The coating is designed to withstand the acidic environment of the stomach and dissolve in the more neutral pH of the intestine.
Rationale for B: Enteric-coated tablets should not be crushed as this destroys the coating designed to protect the stomach lining from the medication's potentially irritating effects, ensuring the medication is released in the intestine.
Rationale for C: This statement is correct; enteric-coated medications are formulated to bypass the stomach and dissolve in the intestine, which can help minimize gastric side effects and irritation.
Rationale for D: It is common for anti-inflammatory medications like naproxen to take several weeks to reach full efficacy. This statement reflects a correct understanding of the medication's expected onset of action.

a. Pleural friction rub: Pleural friction rub is a grating sound heard during inspiration and

expiration and is associated with inflammation of the pleura. It is not typically associated with asthma exacerbation.

b. Fine rales: Fine rales (crackles) are usually heard during inspiration and can be associated with conditions such as pneumonia or pulmonary fibrosis. They are not the typical lung sounds in

asthma exacerbation.

c. Rhonchi: Rhonchi are low-pitched wheezes heard during inspiration and expiration. While they can be associated with asthma, expiratory wheezes are more specific to asthma

exacerbation.

d. Expiratory wheeze: Expiratory wheezes are high-pitched, musical sounds heard during

expiration and are characteristic of asthma exacerbation. They result from narrowed airways and increased airway resistance.
