A nurse is providing care for a client who experienced a myocardial infarction prior to a cardiac arrest. Which of the following laboratory tests will identify early injury to the cardiac muscle?

Creatine kinase (CK) test

Creatine kinase-myocardial band (CK-MB) test

Brain natriuretic peptide (BNP) test

Troponin T test

Answer and Explanation

The Correct Answer is D

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.

Correct Answer is ["A","B","E"]

Explanation

The correct answer is choicea, b, e.

Choice A rationale:A recent weight gain of 1.8 kg (4 lb) with a BMI of 18.9 may indicate potential nutritional issues or underlying health problems that require further investigation.

Choice B rationale:Having an adult child prepare meals could suggest the client may have difficulties with meal preparation, possibly due to physical or cognitive limitations.

Choice C rationale:Clean and weather-appropriate clothing indicates the client is managing their personal hygiene and dressing appropriately, which does not typically prompt further assessment.

Choice D rationale:Receiving regular baths from a home care aide suggests the client has support for personal hygiene, which is generally a positive indicator and does not necessitate further assessment.

Choice E rationale:Frequent toothaches and lack of dental care can indicate poor oral health, which can have significant implications for overall health and nutrition, warranting a more detailed assessment.

Choice F rationale:Making eye contact and smiling while speaking generally indicates good social interaction skills and mental well-being, which does not typically prompt further assessment.

A. Posting swallowing precautions at the head of the client’s bed B. Noting changes in the treatment plan in the client’s medical record. C. Having interdisciplinary team meetings for the client on a regular basis D. Recording the client’s progress in the nurses’ notes

Correct Answer is C

Explanation

Having interdisciplinary team meetings for the client on a regular basis.

This action best promotes communication among staff caring for the client because it allows for consistent and coordinated care planning, information sharing, and goal setting for the client who has expressive aphasia and right hemiparesis following a stroke.

Choice A is wrong because posting swallowing precautions at the head of the client’s bed does not promote communication among staff, but rather informs them of the client’s risk of aspiration due to dysphagia, which is a common complication of stroke.

Choice B is wrong because noting changes in the treatment plan in the client’s medical record is a standard practice that does not necessarily enhance communication among staff, but rather documents the client’s progress and interventions.

Choice D is wrong because recording the client’s progress in the nurses’ notes is also a standard practice that does not necessarily enhance communication among staff but rather provides a summary of the client’s status and care.

Expressive aphasia is an acquired language disorder that affects the ability to produce spoken or written language, while right hemiparesis is a weakness or partial paralysis of the right side of the body.

Both of these conditions are caused by damage to the left hemisphere of the brain, which is responsible for language and motor control of the right side of the body. Stroke and traumatic brain injury are common causes of left hemisphere-damage
