A nurse is completing the medical reconciliation on an elderly client taking several medications. Which of the following prescribed medications places this client at risk for orthostatic hypotension? (Select all that apply.)
furosemide
Simvastatin
Losartan
Nifedipine
Clopidogrel
Correct Answer : A,C,D
A) Furosemide: This is a loop diuretic that can lead to dehydration and electrolyte imbalances, both of which can contribute to orthostatic hypotension. The medication's diuretic effect can cause a significant drop in blood volume, increasing the risk of low blood pressure upon standing.
B) Simvastatin: This medication is used to lower cholesterol levels and is not associated with orthostatic hypotension. It does not have a direct impact on blood pressure or volume.
C) Losartan: As an angiotensin II receptor blocker (ARB), losartan is used to treat hypertension. It can cause vasodilation and may lead to orthostatic hypotension, particularly in elderly clients or those who are volume-depleted.
D) Nifedipine: This calcium channel blocker is used to treat hypertension and can cause vasodilation. It may lead to orthostatic hypotension as well, especially during dose adjustments or if the client is dehydrated.
E) Clopidogrel: This antiplatelet medication is used to prevent blood clots and does not directly cause orthostatic hypotension. Its primary action is to inhibit platelet aggregation, not to affect blood pressure.

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 C
Explanation
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.
