A nurse is reviewing the medication list for a client who has a new prescription for warfarin. The nurse should recognize which is incompatible with warfarin?
Vitamin A
Alprazolam
Vitamin K
Furosemide
The Correct Answer is C
A) Vitamin A: While vitamin A can affect various bodily functions, it is not known to have a direct interaction with warfarin. Therefore, it is not considered incompatible with warfarin therapy.
B) Alprazolam: This medication, a benzodiazepine, is primarily used to treat anxiety and does not have a significant interaction with warfarin. Thus, it is not incompatible with warfarin therapy.
C) Vitamin K: This vitamin is a critical consideration when a client is on warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, so an increased intake of vitamin K can counteract the effects of warfarin, making this the correct answer. Clients on warfarin should maintain a consistent intake of vitamin K to prevent fluctuations in their INR levels.
D) Furosemide: This loop diuretic is used to manage conditions such as heart failure and edema. While it may affect electrolyte levels, it does not have a direct interaction that would render it incompatible with warfarin. It can be safely used alongside warfarin with appropriate monitoring.

Correct Answer is C
Explanation
A) "These tests will enable the provider to determine the heart structure and mobility of the heart valves." This statement is incorrect because cardiac enzyme tests, including troponin levels, do not assess heart structure or valve mobility. Imaging studies like echocardiograms are typically used for evaluating heart structure and function.
B) "Cardiac enzymes assist in diagnosing the presence of congestive heart failure." While cardiac enzymes can provide some information about heart function, they are not specifically used to diagnose congestive heart failure. The primary role of cardiac enzymes, particularly troponin, is in diagnosing myocardial injury, such as an acute myocardial infarction.
C) "Cardiac enzymes like troponin shows there has been damage to the heart tissues and muscle." This statement accurately reflects the purpose of measuring troponin levels. Troponin is a protein released into the bloodstream when heart muscle cells are damaged, making it a crucial biomarker for diagnosing an acute myocardial infarction.
D) "Cardiac enzymes will identify the exact location of the MI." This statement is misleading. While troponin levels can indicate that damage has occurred, they do not provide information about the specific location of the myocardial infarction. Other imaging techniques, such as an angiogram, are needed to determine the exact location of blockages or damage.
Correct Answer is B
Explanation
A) Troponins: These are primarily used to assess for cardiac damage, such as in myocardial infarction. They are not directly related to the effects of spironolactone, so monitoring troponins is not necessary in this context.
B) Potassium: Spironolactone is a potassium-sparing diuretic, which can lead to elevated potassium levels (hyperkalemia). This can have serious implications, including cardiac arrhythmias. Therefore, it is crucial to monitor potassium levels regularly in clients taking
spironolactone to prevent potential complications.
C) Albumin: While albumin levels can provide information about the client's nutritional status and liver function, they are not specifically affected by spironolactone. Monitoring albumin is not a priority when considering the use of this medication.
D) Bicarbonate: Bicarbonate levels are important for assessing acid-base balance. Although spironolactone may have some impact on acid-base status, monitoring bicarbonate is not as critical as monitoring potassium levels, which are directly affected by the medication's action.
