The nurse is caring for a client who has heart failure and a history of asthma. The nurse reviews the provider's orders and recognizes that clarification is needed for which of the following medications?

A. "These tests help determine the degree of damage to the heart tissues." - This is the correct statement. Cardiac enzyme studies, such as creatine kinase (CK), CK-MB, troponin I, and troponin T, are used to assess the extent of myocardial damage during an acute myocardial infarction (MI). Elevated levels of these enzymes indicate myocardial injury and help healthcare providers determine the severity of the heart tissue damage.

B. "Cardiac enzymes will identify the location of the MI." - While cardiac enzymes can confirm the presence of an MI, they do not specifically identify the location of the infarction. Other diagnostic tools, such as electrocardiogram (ECG) and imaging studies, may help determine the location of the MI.

C. "Cardiac enzymes assist in diagnosing the presence of pulmonary congestion." - Cardiac enzymes are not used to diagnose pulmonary congestion. Other diagnostic methods, such as chest X-rays and physical examination, are more appropriate for assessing pulmonary congestion.

D. "These tests will enable the provider to determine the heart structure and mobility of the heart valves." - Cardiac enzyme studies do not provide information about the overall heart structure or the mobility of heart valves. Imaging studies, such as echocardiography, are used for this purpose.

A. Hacking cough: This is the correct answer. Left-sided heart failure can lead to pulmonary congestion, resulting in a cough that is often described as "hacking" or "persistent." This cough may be worse at night when the client is lying down.

B. Abdominal distension: Abdominal distension is more commonly associated with right-sided heart failure, as fluid accumulates in the abdomen (ascites). In left-sided heart failure, fluid accumulates in the lungs, leading to pulmonary symptoms.

C. Dependent edema: Dependent edema is also more commonly associated with right-sided heart failure. In left-sided heart failure, fluid tends to accumulate in the lungs, causing pulmonary congestion and related symptoms.

D. Jugular venous distention: Jugular venous distention is often seen in right-sided heart failure due to impaired blood flow from the right atrium into the right ventricle. This finding is less likely to be prominent in left-sided heart failure.
