A case manager is meeting with a client who asks about using alternative therapies to manage her rheumatoid arthritis.

Answer:D. Troponin T test

Rationale:

A. Creatine kinase (CK) test: While creatine kinase isoenzymes, including CK-MB, can be elevated following myocardial infarction (MI), they are not specific to cardiac muscle injury. CK is found in various tissues throughout the body, so elevated levels can also indicate damage to skeletal muscle or brain tissue, among other sources.

B. Creatine kinase-myocardial band (CK-MB) test: CK-MB is a cardiac-specific isoform of creatine kinase, and elevated levels can indicate myocardial injury, particularly in the context of an acute MI. However, troponin T is a more sensitive and specific marker for myocardial injury.

C. Brain natriuretic peptide (BNP) test: Brain natriuretic peptide is primarily used in the diagnosis and management of heart failure. While elevated BNP levels can indicate heart muscle strain or stress, they are not specific markers for acute myocardial infarction or early injury to the cardiac muscle.

D. Troponin T test: This is the correct answer. Troponin T is a highly specific marker for cardiac muscle injury. Elevated troponin levels can be detected within hours of myocardial infarction and persist for several days, making it an essential tool in the diagnosis of acute coronary syndromes, including myocardial infarction. Troponin T is considered one of the gold standard biomarkers for detecting early injury to the cardiac muscle.

The correct answer is choice C. Administering potassium via IV bolus is an example of malpractice in nursing.

This is because potassium is a medication that can cause cardiac arrest if given too quickly or in high doses. A nurse who administers potassium via IV bolus is not providing the standard of care that a similarly trained nurse would have offered under the same circumstances.

This could result in harm or death to the patient.

Choice A is wrong because placing a yellow bracelet on a client who is at risk for falls is not malpractice, but rather a safety measure.

A yellow bracelet indicates that the client needs assistance with mobility and should not be left alone. This is a common practice in many health care facilities to prevent falls and injuries.

Choice B is wrong because leaving a nasogastric tube clamped after administering oral medication is not malpractice, but rather a mistake.

A nasogastric tube is a tube that goes through the nose and into the stomach to deliver nutrition or medication.

It should be unclamped after giving oral medication to allow the medication to enter the stomach and prevent reflux or aspiration. However, this error does not rise to the level of malpractice unless it causes harm to the patient, such as vomiting, choking, or infection.

Choice D is wrong because documenting communication with a provider in the progress notes of the client’s medical record is not malpractice, but rather a good practice. A nurse
