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 B
Explanation
A) Take the medication with meals:
Nitroglycerin oral, sustained-release capsules should be taken on an empty stomach to enhance absorption. Taking them with meals may delay or alter the absorption rate, potentially affecting the medication's effectiveness.
B) Swallow the capsules whole:
Nitroglycerin sustained-release capsules should be swallowed whole without crushing or chewing. Breaking or crushing the capsules can lead to rapid release of the medication, which may cause adverse effects such as sudden drops in blood pressure or headaches.
C) Stop taking the medication if you develop headaches:
Headaches are a common side effect of nitroglycerin due to its vasodilatory effects. Clients are often advised to continue taking the medication as prescribed and inform their healthcare provider about persistent or severe headaches.
D) Take 1 capsule at the onset of anginal pain:
Nitroglycerin is typically used to relieve anginal pain when it occurs. However, sustained-release formulations are not intended for immediate relief of acute angina attacks. Fast-acting formulations like sublingual nitroglycerin tablets are used for acute pain relief.
Correct Answer is C
Explanation
A) "Take the medication with meals":
Rifampin should ideally be taken on an empty stomach, as food can interfere with its absorption. Taking it with meals may decrease its effectiveness. Instructing the client to take rifampin at least 1 hour before or 2 hours after meals ensures optimal absorption and effectiveness of the medication.
B) "Purified protein derivative skin test results will improve in 3 months":
Rifampin does not affect the results of the purified protein derivative (PPD) skin test for tuberculosis. The PPD test measures the immune response to tuberculosis infection and is not influenced by rifampin therapy. It's important to clarify that the PPD test is used for diagnosis and monitoring of tuberculosis infection, not as a marker for medication effectiveness.
C) "Urine and other secretions will turn orange":
This is a common and harmless side effect of rifampin. It can cause discoloration of urine, sweat, tears, and other secretions to an orange-red color. Informing the client about this side effect prevents unnecessary concern and ensures they are aware of what to expect while taking rifampin.
D) "Expect to have insomnia while taking this medication":
Insomnia is not a common side effect of rifampin. Rifampin can cause other side effects such as gastrointestinal upset, hepatotoxicity, and flu-like syndrome, but insomnia is not typically reported. It's important to educate the client about potential side effects that are more commonly associated with rifampin therapy.
