A nurse assesses a client who is prescribed a medication that inhibits angiotensin I from converting into angiotensin II (angiotensin-converting enzyme (ACE) inhibitor). For which expected therapeutic effect should the nurse assess?

A. Dyspnea: Dyspnea, or difficulty breathing, can be a sign of fluid volume excess. Fluid overload can cause pulmonary congestion and lead to respiratory distress. This is a critical manifestation that should be reported.

B. Edema: Edema is a common sign of fluid retention, especially in the lower extremities, and is indicative of fluid volume excess. This should be monitored and reported if observed during the transfusion.

C. Bradycardia: Bradycardia is typically not a sign of fluid volume excess. In fluid volume excess, the heart often tries to compensate for the increased fluid by increasing its rate (tachycardia) to maintain cardiac output, or the rate might remain relatively normal.

D. Hypertension: Hypertension, or high blood pressure, can occur with fluid volume excess as the extra fluid in the circulatory system increases the workload on the heart and raises blood pressure. This is a critical sign of fluid overload that requires reporting.

E. Weakness: Weakness can occur in a variety of conditions, including fluid volume excess, but it is a nonspecific symptom. It is less directly associated with fluid overload compared to the other findings like dyspnea, edema, and hypertension.

A. Repeatedly asking "Where am I?": This can be a sign of confusion or disorientation due to the buildup of CO2 in respiratory acidosis. As CO2 accumulates in the blood, it can lead to impaired brain function, resulting in confusion or altered mental status.

B. Difficult to arouse: Respiratory acidosis leads to increased CO2 levels, which can depress the central nervous system, causing lethargy and difficulty arousing the patient. This is a common manifestation of respiratory acidosis, especially in severe cases.

C. Barrel chest: A barrel chest is a long-term, chronic structural change in the chest wall, commonly seen in individuals with advanced COPD. While a client with COPD will likely have a barrel chest, it is a chronic anatomical finding, not an acute clinical sign resulting from current respiratory acidosis.

D. Dysrhythmias: Elevated CO2 levels can affect the heart's electrical conduction system, leading to arrhythmias. This is a known complication of respiratory acidosis, particularly in COPD patients, as the body struggles to compensate for the acidotic state.

E. Rapid, shallow respirations: Rapid, shallow respirations are more typical of respiratory alkalosis, where the body is trying to expel CO2 quickly. In respiratory acidosis, the body may attempt to compensate by increasing the rate of breathing, but the respirations are typically deep and labored (Kussmaul's respirations), not shallow.
