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 D rationale:

The nurse should seek clarification for the prescribed medication Propranolol when caring for a client with an exacerbation of asthma. Propranolol is a non-selective beta-blocker, and its use can exacerbate bronchoconstriction and potentially worsen asthma symptoms. In patients with asthma, non-selective beta-blockers are generally contraindicated. The nurse should consult with the provider to ensure that Propranolol is the appropriate choice, as there may be safer alternatives to manage the client's condition without worsening their asthma.

Choice A rationale:

Prednisone is a corticosteroid commonly used to reduce inflammation and manage asthma exacerbations. It is an appropriate medication for asthma management and does not require clarification.

Choice B rationale:

Montelukast is a leukotriene receptor antagonist that is also used in the management of asthma. It helps to reduce airway inflammation and bronchoconstriction. Montelukast is an appropriate choice for asthma and does not need further clarification.

Choice C rationale:

Aminophylline is a bronchodilator that can be used in the treatment of asthma. While it may have potential side effects and interactions, it is not the first medication that needs clarification in this scenario. Propranolol, due to its potential to worsen asthma symptoms, takes precedence.
