A nurse is collecting data from a client whose arterial blood gas values reveal a pH of 7.24, PaCO2 of 53, and an HCO3 of 24. The nurse should prepare to treat the client for which of the following acid-base imbalances?

a. Asthma: While asthma can cause dyspnea and fatigue, it is not typically associated with tachycardia and edema.

b. Heart failure: Heart failure is characterized by symptoms such as dyspnea, fatigue,

tachycardia, and edema. Tachycardia may be a compensatory response to maintain cardiac output, and edema can result from fluid retention.

c. Aortic valve regurgitation: Aortic valve regurgitation may cause symptoms such as dyspnea and fatigue, but it is not typically associated with tachycardia and edema.

d. Aortic stenosis: Aortic stenosis may lead to symptoms such as dyspnea, but tachycardia and edema are not typical features of aortic stenosis.

a. Bradycardia: Atenolol is a beta-blocker that can slow down the heart rate, leading to

bradycardia. Monitoring the client for signs of bradycardia, such as dizziness, fatigue, or fainting, is important.

b. Anemia: Atenolol is not known to cause anemia. Monitoring for anemia is not a specific concern with this medication.

c. Hypokalemia: Atenolol is not associated with causing hypokalemia. However, beta-blockers in general may affect potassium levels indirectly.

d. Neutropenia: Atenolol is not typically associated with causing neutropenia. Monitoring for neutropenia is not a specific concern with this medication.
