A client came into the emergency room with a possible myocardial infarction. The provider orders a series of blood tests to be drawn, which lab should the nurse anticipate will be drawn?

Brain Natriuretic Peptide (BNP)

Total Lactate Dehydrogenase (LDH)

Troponin

Creatinine

Answer and Explanation

The Correct Answer is C

A. Brain Natriuretic Peptide (BNP) is a marker for heart failure, not the primary diagnostic test for myocardial infarction (MI).
B. Total Lactate Dehydrogenase (LDH) was historically used but is not specific for MI and has been replaced by troponin testing.
C. Troponin is correct. Cardiac-specific troponins (Troponin I and Troponin T) are the gold standard for detecting myocardial injury. Elevated levels indicate myocardial damage and are crucial for diagnosing MI.
D. Creatinine is important for assessing kidney function but is not a marker for myocardial infarction.

Correct Answer is D

Explanation

A. A balloon inflation within the artery describes percutaneous coronary intervention (PCI) or angioplasty, not CABG.
B. A medication to dissolve a blood clot refers to thrombolytic therapy, which is not part of a CABG procedure.
C. Injecting dye to outline heart vessels describes a coronary angiogram, which is a diagnostic procedure but not a treatment.
D. CABG involves using a healthy artery or vein to bypass the blocked portion of a coronary artery, restoring proper blood flow to the heart muscle.

A. Encourage an increased intake of the client's favorite drink B. Continue to monitor daily weights and edema and document findings. C. Perform a head-to-toe assessment, including vital signs D. Check the record to determine code status

Correct Answer is C

Explanation

A. Encouraging increased fluid intake is incorrect. Clients with heart failure are at risk for fluid overload, and excessive fluid intake can worsen symptoms.
B. Simply monitoring and documenting findings is insufficient. A 2-pound weight gain in a short period suggests fluid retention and worsening heart failure, requiring further assessment and possible intervention.
C. Performing a head-to-toe assessment, including vital signs, is correct. The nurse should assess for worsening heart failure, including lung sounds (crackles), respiratory effort, blood pressure, and oxygen saturation, to determine if immediate interventions are needed.
D. Checking code status is not the priority. While knowing a client’s code status is important, the immediate concern is assessing for signs of fluid overload and potential decompensation.
