A nurse is reviewing the laboratory results of a client who is taking a loop diuretic and notes the client's potassium level is 3.0 mEq/L. Which of the following physiological responses should the nurse expect related to the client's hypokalemia?

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.

Choice A rationale:

Taking hydrochlorothiazide on an empty stomach is not a requirement for this medication. Hydrochlorothiazide is a diuretic used to treat conditions like hypertension and edema. It can be taken with or without food, and food may help reduce stomach upset for some individuals.

Choice B rationale:

Muscle weakness is an adverse effect of hydrochlorothiazide. Therefore, it is not an expected outcome. Hydrochlorothiazide is a thiazide diuretic, and one of its common side effects is potassium loss through increased urine output. This can lead to muscle weakness and cramping. The nurse should educate the client about the signs and symptoms of low potassium and the importance of including potassium-rich foods in their diet.

Choice C rationale:

Increasing daily intake of foods high in potassium is essential information to include in the teaching for a client taking hydrochlorothiazide. Thiazide diuretics like hydrochlorothiazide can cause potassium depletion, which may result in adverse effects like muscle weakness, cramping, and cardiac dysrhythmias. Therefore, advising the client to consume potassium-rich foods, such as bananas, oranges, and potatoes, can help counteract the potassium loss associated with the medication.

Choice D rationale:

Taking the medication at bedtime is not a specific requirement for hydrochlorothiazide. Thiazide diuretics can be taken at various times of the day, depending on the client's preferences and when they are most compliant with their medication regimen. The timing of administration should be consistent to maintain the medication's effectiveness.
