A nurse is admitting a client who is having an exacerbation of asthma.
When reviewing the provider's orders, the nurse recognizes that clarification is needed for which of the following prescribed medications?
Prednisone.
Montelukast.
Aminophylline.
Propranolol.
The Correct Answer is D
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.

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.
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.
