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 B

Explanation

Choice A reason
Administering naloxone to the newborn is not appropriate. Naloxone is an opioid antagonist used to reverse the effects of opioid overdose in adults. It is not typically used for newborns with neonatal abstinence syndrome. The management of NAS is primarily supportive, and medications may be prescribed to help manage specific withdrawal symptoms, but naloxone is not a standard treatment for NAS.

Choice B reason:

Minimizing noise in the newborn's environment is a crucial action in the plan of care is the correct action to be included. Newborns experiencing NAS can be easily overstimulated, and loud noises can exacerbate their withdrawal symptoms and distress. Creating a calm and quiet environment helps reduce agitation and promotes better sleep and overall comfort.

Choice C reason

Swaddling the newborn with his leg extended is not appropriate in this case. Swaddling can be beneficial for some newborns, but the specific positioning and swaddling techniques should be individualized based on the newborn's needs and preferences. Extending the newborn's legs may not necessarily be the best approach, as it may not provide comfort or address the symptoms associated with NAS.

Choice D reason:

Maintaining eye contact with the newborn during feedings is not appropriate in this case. While maintaining eye contact during feedings is an essential aspect of bonding and promoting parent-newborn attachment, it may not be the primary focus in managing neonatal abstinence syndrome. The plan of care for a newborn with NAS would primarily involve managing withdrawal symptoms, providing comfort measures, and addressing the newborn's unique needs during this challenging period.

A. ECG results. B. Client's report of lack of food in home. C. client's report of lack of access to bank accounts. D. Clients avoidance of eye contact. E. Clients report of weight loss. F. Numerous bruises in various stages of healing.

Correct Answer is ["B","C","D","E","F"]

Explanation

Answer is B, C, D, E, F. These are the findings that suggest possible elder abuse or neglect.

B: Client’s report of lack of food in home. This may indicate neglect by the adult child who is supposed to provide adequate nutrition for the client.
C: Client’s report of lack of access to bank accounts. This may indicate financial abuse by the adult child who is controlling the client’s money without his permission.
D: Client’s avoidance of eye contact. This may indicate emotional abuse by the adult child who is intimidating or threatening the client.
E: Client’s report of weight loss. This may indicate neglect by the adult child who is not meeting the client’s basic needs or physical abuse by the adult child who is causing bodily harm to the client.
F: Numerous bruises in various stages of healing. This may indicate physical abuse by the adult child who is hitting or injuring the client.

A: ECG results. This is not a finding that suggests elder abuse or neglect. It is a diagnostic test that measures the electrical activity of the heart and can help detect cardiac problems. It does not provide information about the client’s social or emotional well-being.

Normal ranges for vital signs:.

Temperature: 36.1°C to 37.2°C (97°F to 99°F).
Heart rate: 60 to 100 beats per minute.
Blood pressure: less than 120/80 mm Hg.
Respiratory rate: 12 to 20 breaths per minute.
SpO2: 95% to 100% on room air. Table for BMI categories:

BMI	Weight Status
Below 18.5	Underweight
18.5 to 24.9	Normal
25.0 to 29.9	Overweight
30.0 and above	Obese

The client’s BMI is 18.3, which indicates he is underweight and may be malnourished or have a medical condition that causes weight loss.
