A nurse is collecting data from a client who is having an acute asthma exacerbation.
When auscultating the client's chest, the nurse should expect to hear which of the following sounds?
Fine rales.
Rhonchi.
Expiratory wheeze.
Pleural friction rub.
The Correct Answer is C
Choice A rationale:
Fine rales Fine rales, also known as crackles, are typically associated with conditions like pulmonary edema, pneumonia, or interstitial lung diseases. These sounds are often described as "crackling" or "popping" and are heard during inspiration. In an acute asthma exacerbation, expiratory wheezing is more characteristic than fine rales.
Choice B rationale:
Rhonchi Rhonchi are continuous, low-pitched sounds that can be heard in conditions like chronic obstructive pulmonary disease (COPD) or bronchitis. They are typically present during both inspiration and expiration. In an acute asthma exacerbation, you would expect to hear wheezing during expiration, which is different from the characteristics of rhonchi.
Choice D rationale:
Pleural friction rub Pleural friction rub is a grating, leathery sound caused by the inflamed pleura rubbing against each other. It is typically heard during both inspiration and expiration and is associated with conditions like pleuritis or pleurisy. It is not commonly associated with acute asthma exacerbation. Now, let's move on to the next question.

Correct Answer is B
Explanation
Choice A rationale:
A client who takes glyburide for type 2 diabetes mellitus is not at significant risk for developing digoxin toxicity. Glyburide is an antidiabetic medication and does not interact directly with digoxin.
Choice B rationale: Furosemide, a loop diuretic, can cause electrolyte imbalances such as hypokalemia (normal potassium levels: 3.5 to 5.0 mEq/L) and hypomagnesemia (normal magnesium levels: 1.7 to 2.2 mg/dL). These imbalances increase the sensitivity to digoxin and the risk of toxicity. Digoxin toxicity is associated with symptoms like nausea, vomiting, and arrhythmias. Furosemide's impact on electrolytes makes it a significant risk factor for digoxin toxicity.
Choice C rationale: Cimetidine, a histamine H2 receptor antagonist, can inhibit the metabolism of certain drugs by affecting liver enzymes. However, it does not significantly alter digoxin levels or increase the risk of toxicity. Normal liver enzyme levels include ALT (7 to 56 U/L) and AST (10 to 40 U/L). While cimetidine may interact with other medications, its effect on digoxin is minimal.
Choice D rationale:
A client who takes azelastine for allergic rhinitis is not at significant risk for developing digoxin toxicity. Azelastine is an antihistamine and does not interact directly with digoxin.
Correct Answer is C
Explanation
The correct answer is: C.
Choice A reason: A pH of 7.50 and HCO3 of 31 mm Hg suggest a metabolic alkalosis due to the high bicarbonate level. However, during a panic attack, hyperventilation leads to respiratory alkalosis, not metabolic, due to the excessive exhalation of CO2, which is not consistent with this option.
Choice B reason: A pH of 7.30 and HCO3 of 19 mm Hg indicate a metabolic acidosis due to the low bicarbonate level. This is not typically associated with hyperventilation during a panic attack, which usually causes respiratory alkalosis, characterized by a decrease in CO2 levels and an increase in pH.
Choice C reason: A pH of 7.47 and PaCO2 of 31 mm Hg are indicative of respiratory alkalosis, which is expected during hyperventilation as a result of a panic attack. Hyperventilation causes a decrease in carbon dioxide (PaCO2) levels, leading to an increase in pH. The normal ranges for arterial blood gases are: pH 7.35-7.45, PaCO2 35-45 mm Hg, and HCO3 22-26 mEq/L.
Choice D reason: A pH of 7.32 and PaCO2 of 50 mm Hg suggest respiratory acidosis due to the elevated PaCO2 level. This would be more consistent with hypoventilation, which is not the case during a panic attack where hyperventilation occurs.
