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B. Total Lactate Dehydrogenase (LDH) was historically used but is not specific for MI and has been replaced by troponin testing.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 C

Explanation

A. Immediately notify the provider . A rise in the water seal chamber with inspiration (tidaling) is a normal finding, indicating proper function of the chest drainage system. There is no need for immediate provider notification.
B. Clamp the chest tube near the water seal . Clamping the chest tube can lead to a tension pneumothorax by trapping air inside the pleural space. This action is only done temporarily for specific indications, such as assessing for an air leak or changing the drainage system.
C. Continue to monitor the client . Tidaling (fluctuation of water with inspiration and expiration) is expected in the water seal chamber. The nurse should continue to monitor for any sudden cessation of tidaling (which may indicate obstruction) or continuous bubbling (which may indicate an air leak).
D. Reposition the client toward the left side . Position changes do not affect normal tidaling in a functioning chest tube system. However, frequent repositioning is encouraged to promote lung expansion.

A. The client holds his breath for 10 seconds after inhaling the medication. B. The client waits 10 min between inhalations. C. The client takes a quick inhalation while releasing the medication from the inhaler. D. The client exhales as the medication is released from the inhaler.

Correct Answer is A

Explanation

A. Holding the breath for 10 seconds after inhaling allows the medication to be absorbed into the lungs effectively.
B. The client should wait at least 1 minute between inhalations if a second dose is needed, not 10 minutes.
C. The client should take a slow, deep breath while releasing the medication to ensure better lung deposition.
D. The client should inhale while pressing the inhaler, not exhale, to properly receive the medication.
