A nurse is reviewing the chart of a client who is scheduled to have radiological studies of the kidneys performed with the use of IV contrast dye. Which of the following client medications should the nurse withhold prior to the examination?
Pantoprazole
Simvastatin
Valsartan
Metformin
The Correct Answer is D
A) Pantoprazole:
Pantoprazole is a proton pump inhibitor used to reduce stomach acid. It does not typically require withholding before radiological studies with IV contrast dye.
B) Simvastatin:
Simvastatin, a statin medication used to lower cholesterol, does not need to be withheld before radiological studies with IV contrast dye.
C) Valsartan:
Valsartan, an angiotensin II receptor blocker used for hypertension, does not typically need to be withheld before radiological studies with IV contrast dye.
D) Metformin:
Metformin, an oral antidiabetic medication, should be withheld before radiological studies with IV contrast dye. There is a risk of lactic acidosis when metformin interacts with IV contrast dye, particularly in clients with impaired renal function.

Correct Answer is D
Explanation
A) To provide analgesia:
Aspirin is primarily used as an antiplatelet medication in the context of myocardial infarction (MI) and coronary artery disease (CAD). While aspirin can provide mild pain relief (analgesia), its main therapeutic effect in this scenario is not for pain management.
B) To reduce inflammation:
Aspirin does have anti-inflammatory properties, but its use in preventing cardiovascular events like myocardial infarction is primarily due to its antiplatelet effects rather than its anti-inflammatory properties.
C) To prevent fever:
Aspirin is sometimes used to reduce fever, but its role in preventing cardiovascular complications like clot formation after myocardial infarction is more crucial and unrelated to fever prevention.
D) To prevent blood clotting:
Aspirin inhibits platelet aggregation and reduces the risk of blood clot formation. This antiplatelet effect is beneficial in preventing further clot formation in coronary arteries, which is critical in the management of myocardial infarction and coronary artery disease.
Correct Answer is ["1"]
Explanation
To determine how many hydrochlorothiazide tablets to administer per dose, we can perform a simple calculation:
Identify the prescribed dose: The nurse needs to administer 25 mg of hydrochlorothiazide per dose.
Identify the tablet strength: Each available tablet contains 50 mg of hydrochlorothiazide.
Calculate the number of tablets: We need to find out how many 50 mg tablets are needed to deliver the prescribed 25 mg dose.
Here, dividing the prescribed dose by the tablet strength will tell us how many tablets are required:
Number of tablets = Prescribed dose / Tablet strength
Number of tablets = 25 mg / 50 mg/tablet
Since the division results in 0.5, we need to round to the nearest whole number for medication administration.
Therefore, the nurse should administer 1 tablet of hydrochlorothiazide per dose.
