A nurse in a provider's office is reviewing the laboratory results of four clients who take digoxin.

Which of the following clients is at risk for developing digoxin toxicity?

A client who takes glyburide for type 2 diabetes mellitus.

A client who takes furosemide for hypertension.

A client who takes cimetidine to reduce gastric acid secretion.

A client who takes azelastine for allergic rhinitis.

Answer and Explanation

The Correct Answer is B

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 ["A","C","D","E"]

Explanation

Choice A rationale:

Dyspnea is a common finding in clients with emphysema. Emphysema is a chronic obstructive pulmonary disease (COPD) characterized by the destruction of the alveoli in the lungs, leading to difficulty breathing and shortness of breath. The loss of alveoli reduces the surface area for gas exchange, causing dyspnea.

Choice B rationale:

Bradycardia is not typically associated with emphysema. In fact, it is more common for clients with emphysema to have an increased heart rate (tachycardia) due to the body's compensatory response to low oxygen levels in the blood.

Choice C rationale:

Clubbing of the fingers is often seen in clients with chronic respiratory conditions like emphysema. It is a result of chronic hypoxia and is characterized by the abnormal rounding and thickening of the fingertips and nail beds.

Choice D rationale:

Barrel chest is a common physical finding in clients with emphysema. It is characterized by an increase in the anteroposterior diameter of the chest due to overinflation of the lungs. This change in chest shape is a result of chronic air trapping and hyperinflation, which are hallmarks of emphysema.

Choice E rationale:

Shallow respirations are expected in clients with emphysema. Due to the loss of alveolar elasticity and increased airway resistance, clients with emphysema tend to take shallow breaths, which are less effective for oxygen exchange.

A. Facial flushing. B. Dry cough. C. Decreasing respiratory rate. D. Increasing dyspnea.

Correct Answer is D

Explanation

Choice A rationale:

Facial flushing. Facial flushing is not typically associated with atelectasis. Atelectasis is the collapse of a portion of the lung, which can lead to decreased oxygenation and respiratory distress but does not directly cause facial flushing. Flushing may be related to other factors such as fever or allergic reactions.

Choice B rationale:

Dry cough. A dry cough can be a common symptom of atelectasis. As the lung tissue collapses and airways become obstructed, it can lead to irritation and a dry, non-productive cough as the body attempts to clear the airway. So, a dry cough is an expected finding in a client with atelectasis.

Choice C rationale:

Decreasing respiratory rate. A decreasing respiratory rate is not typically associated with atelectasis. In fact, atelectasis often leads to an increased respiratory rate as the body tries to compensate for the reduced oxygen exchange. The patient may experience tachypnea (rapid breathing) as a result.

Choice D rationale:

Increasing dyspnea. Increasing dyspnea is a common and expected finding in a client with atelectasis. As lung tissue collapses and oxygen exchange is compromised, the patient will likely experience worsening shortness of breath. This is a concerning symptom and should be closely monitored, as it may indicate a need for intervention to improve lung expansion and oxygenation.
