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) Dyspnea:
Diphenhydramine primarily addresses allergic reactions such as urticaria (hives) rather than respiratory symptoms like dyspnea associated with blood transfusion reactions.
B) Fever:
The administration of diphenhydramine during blood transfusions is aimed at mitigating allergic reactions, particularly urticaria, rather than fever as a symptom.
C) Low-back pain:
Diphenhydramine is not indicated for preventing or managing low-back pain, which is not typically associated with allergic reactions to blood transfusions.
D) Urticaria:
Diphenhydramine is administered to prevent or reduce symptoms of allergic reactions, particularly urticaria (hives), which can occur during blood transfusions due to immune responses to transfused blood components.
Correct Answer is A
Explanation
A) The client should use an electric razor while on this medication:
Using an electric razor is recommended for clients taking warfarin because it reduces the risk of cuts and bleeding, which can be difficult to control due to the anticoagulant effects of warfarin. This advice helps minimize the risk of injury and excessive bleeding.
B) Warfarin increases the risk for deep vein thrombosis:
Warfarin is an anticoagulant that is actually used to prevent and treat deep vein thrombosis (DVT) and other thromboembolic conditions. This statement is incorrect because warfarin reduces the risk of clot formation, rather than increasing it.
C) Nose bleeds are common during initial treatment:
While nosebleeds can occur as a side effect of warfarin due to its anticoagulant properties, they are not considered common or normal. Persistent or frequent nosebleeds should be reported to a healthcare provider, as they may indicate that the dosage needs adjustment.
D) If he misses a dose, he should double the dose at the next scheduled time:
Doubling the dose of warfarin if a dose is missed is not recommended. Doing so can significantly increase the risk of bleeding. The correct action for a missed dose is to take it as soon as remembered, but if it is close to the time for the next dose, skip the missed dose and continue with the regular schedule. Clients should follow specific instructions from their healthcare provider regarding missed doses.
