A nurse is assisting the primary care provider to determine if a patient had a myocardial infarction.
Which laboratory values should the nurse check?

Albumin and aldosterone.

Sodium and potassium.

Creatine phosphate (CK-MB) and troponin 1.

Cholesterol and HDL.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Albumin and aldosterone. Rationale: Albumin and aldosterone are not typically used to diagnose myocardial infarction. These are not specific markers for cardiac injury. Choice A is incorrect.

Choice B rationale:

Sodium and potassium. Rationale: Sodium and potassium levels are important for assessing electrolyte balance, but they are not specific indicators of myocardial infarction. Choice B is incorrect.

Choice C rationale:

Creatine phosphate (CK-MB) and troponin 1. Rationale: Creatine kinase-MB (CK-MB) and troponin 1 are specific cardiac markers that are elevated in the blood following a myocardial infarction. CK-MB is an isoenzyme of creatine kinase found primarily in the heart, and troponin is a protein released from damaged heart muscle cells. Elevated levels of these markers are indicative of myocardial infarction. Choice C is the correct answer.

Choice D rationale:

Cholesterol and HDL. Rationale: Cholesterol and HDL (High-Density Lipoprotein) levels are relevant for assessing cardiovascular risk but are not specific markers for myocardial infarction. Choice D is incorrect.

Correct Answer is D

Explanation

Choice A rationale:

Troponin T is a cardiac biomarker used to diagnose myocardial infarction, not to determine the severity of heart failure. It is not the most appropriate laboratory result to monitor for heart failure severity.

Choice B rationale:

C-reactive protein is a marker of inflammation and is not typically used to determine the severity of heart failure. While inflammation can be present in heart failure, it is not a specific marker for its severity.

Choice C rationale:

Potassium levels can be important in heart failure management, but they do not directly indicate the severity of heart failure. Abnormal potassium levels can be a consequence of heart failure and its treatment.

Choice D rationale:

Brain natriuretic peptide (BNP) is the most appropriate laboratory result to monitor to determine the severity of heart failure in a patient. Elevated levels of BNP are associated with increased severity of heart failure. BNP is released by the heart in response to increased pressure and volume, which occurs in heart failure.

A. Chorea. B. M proteins. C. C-reactive protein. D. Streptolysin O. .

Correct Answer is B

Explanation

Choice A rationale:

"Chorea" is not related to the pathophysiology of acute rheumatic fever. Chorea is a movement disorder, but it is not a term associated with the immune response to group A streptococcal cell membrane antigens.

Choice B rationale:

"M proteins" are the key component involved in the pathophysiology of acute rheumatic fever. Group A streptococcal M proteins trigger an abnormal immune response that can lead to acute rheumatic fever and its associated complications, including rheumatic heart disease.

Choice C rationale:

"C-reactive protein" is not the primary antigen or component involved in the pathophysiology of acute rheumatic fever. While C-reactive protein may increase in response to inflammation, it is not the main factor responsible for the development of this condition.

Choice D rationale:

"Streptolysin O" is not the primary antigen involved in the pathophysiology of acute rheumatic fever. Streptolysin O is a toxin produced by group A streptococci, but it is not the antigen responsible for the abnormal immune response leading to acute rheumatic fever. .
