A nurse is caring for a client who reports chest pain. Which of the following laboratory findings indicates myocardial damage?
Troponin 11.8 ng/mL
Erythrocyte sedimentation rate (ESR) 17 mm/hr
Human B-type natriuretic peptide 88 pg/ml.
aPTT 80 seconds
The Correct Answer is A
A.
A. Troponin is a protein released into the bloodstream when there is damage to the heart muscle (myocardium), such as during a heart attack. Elevated troponin levels indicate myocardial injury or damage, making this the correct choice for indicating myocardial damage.
B. Erythrocyte sedimentation rate (ESR) measures the rate at which red blood cells settle in a tube of blood. It is a non-specific marker of inflammation and is not specific to myocardial damage.
C. Human B-type natriuretic peptide (BNP) is released by the heart in response to increased pressure and volume. Elevated levels are indicative of heart failure, not necessarily myocardial damage.
D. Activated partial thromboplastin time (aPTT) measures the time it takes for blood to clot. It is used to monitor the effectiveness of anticoagulant therapy and is not specific to myocardial
damage.

Correct Answer is B
Explanation
A. Place the client's valuables in the facility's safe - While securing the client's valuables is important, it is not the priority upon admission.
B. Observe the client's level of mobility - This is the priority as it allows the nurse to assess the client's immediate physical condition and risk of falls or other mobility-related issues.
C. Administer prescribed medications - Medication administration can wait until the client's initial assessment, including mobility, has been completed.
D. Electronically enter the prescriptions from the provider - Entering prescriptions can be done after the initial assessment and immediate needs of the client have been addressed.
Correct Answer is B
Explanation
A. Levothyroxine is a medication used to treat hypothyroidism by replacing or supplementing thyroid hormone. It is not typically associated with decreased blood pressure.
B. Weight loss can be an indicator that levothyroxine therapy is effective in treating hypothyroidism. Hypothyroidism often leads to weight gain, and successful treatment with levothyroxine can help reverse this trend.
C. Levothyroxine therapy primarily targets thyroid hormone levels and is not directly associated with decreased inflammation.
D. Seizures are not typically associated with hypothyroidism or its treatment with levothyroxine.
The effectiveness of levothyroxine is primarily assessed by monitoring thyroid function tests and clinical symptoms such as weight loss, improved energy levels, and resolution of hypothyroid symptoms.
