A client with congestive heart failure presents with a dry, persistent cough. The nurse should recognize this symptom as:

Hemoptysis

Dyspnea

Paroxysmal nocturnal dyspnea

Cardiac asthma

Answer and Explanation

The Correct Answer is D

A) This choice is incorrect because hemoptysis refers to coughing up blood from the respiratory tract, which is not described by the client.

B) This choice is incorrect because dyspnea refers to difficulty breathing or shortness of breath, not a dry, persistent cough.

C) This choice is incorrect because paroxysmal nocturnal dyspnea is characterized by sudden breathlessness that awakens the client from sleep, not a dry cough.

D) This choice is correct. Cardiac asthma is a form of wheezing or coughing that occurs as a result of fluid accumulation in the lungs due to congestive heart failure. It is not caused by asthma but is a manifestation of heart failure impacting the respiratory system.

Correct Answer is A

Explanation

A) This choice is correct. Beta-blockers should not be abruptly discontinued, as sudden discontinuation can lead to rebound effects and worsen the client's condition. Gradual tapering of the medication is necessary under the guidance of the healthcare provider.

B) This choice is incorrect because taking a beta-blocker with a high-fat meal is not necessary. Beta-blockers can be taken with or without food, but consistent administration is essential for optimal therapeutic effects.

C) This choice is incorrect because limiting fluid intake is not specific to the administration of beta-blockers. Fluid intake may need to be adjusted based on the client's overall fluid balance and congestive heart failure status, but it is not a direct instruction related to the medication.

D) This choice is incorrect because the timing of beta-blocker administration varies depending on the specific beta-blocker prescribed and the client's individual response. Some beta-blockers may be taken in the morning, while others may be taken in the evening. The client should follow the prescribed schedule given by the healthcare provider.

A. Complete blood count (CBC) B. Basic metabolic panel (BMP) C. Brain natriuretic peptide (BNP) level D. C-reactive protein (CRP) level

Correct Answer is C

Explanation

A) This choice is incorrect because a complete blood count (CBC) is a general blood test that measures different components of the blood, such as red blood cells, white blood cells, and platelets. It is not specifically used to measure heart strain or diagnose CHF.

B) This choice is incorrect because a basic metabolic panel (BMP) is a blood test that measures electrolytes, kidney function, and glucose levels. It is not specific to diagnosing CHF.

C) This choice is correct. A brain natriuretic peptide (BNP) level is a blood test specifically used to measure heart strain. Elevated BNP levels can indicate heart failure, making it a valuable diagnostic tool in assessing suspected CHF.

D) This choice is incorrect because a C-reactive protein (CRP) level is a marker of inflammation and is not specific to diagnosing CHF.
