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

Answer and Explanation

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 A

Explanation

A) "Apply the ointment in a thin line into the conjunctival sac":
Applying the antibiotic ophthalmic ointment in a thin line into the conjunctival sac ensures that the medication comes into direct contact with the infected area of the eye. This method facilitates optimal absorption and distribution of the medication to effectively treat bacterial conjunctivitis. Ensuring correct application technique helps prevent unnecessary wastage and ensures that the medication reaches its intended site, maximizing therapeutic benefits.

B) "Keep your eye open for 30 sec after instilling the ointment":
While keeping the eye open for a brief period after instilling the ointment can facilitate distribution, it is secondary to ensuring the correct placement of the medication into the conjunctival sac, where it can act directly on the infection.

C) "Use a sterile glove and applicator to apply the antibiotic ointment":
Using a sterile glove and applicator may not be routinely necessary for applying antibiotic ophthalmic ointment. Clean hands and ensuring the tip of the tube or applicator does not touch any surfaces can maintain appropriate hygiene and prevent contamination.

D) "Always wipe from the outer to the inner canthus when wiping away secretions":
While wiping secretions should be done gently to avoid irritation, the direction (outer to inner canthus) primarily aims to prevent spreading infection to the unaffected eye. It is important but not directly related to the technique of applying ophthalmic ointment.

A. "This medication prevents gastric acid secretion in the stomach." B. "This medication kills the bacteria which cause ulcers." C. "This medication neutralizes gastric acid after it is secreted." D. "This medication adheres to the ulcer and protects it from gastric acid."

Correct Answer is D

Explanation

A) "This medication prevents gastric acid secretion in the stomach":
Sucralfate does not affect gastric acid secretion. It works by forming a protective barrier over ulcers, adhering to the ulcer surface and shielding it from gastric acid and other digestive enzymes. This mechanism helps to promote healing of duodenal ulcers by providing a protective environment for the ulcer to heal without exposure to gastric acid.

B) "This medication kills the bacteria which cause ulcers":
Sucralfate does not possess antibacterial properties and does not target bacteria like Helicobacter pylori, which can cause ulcers. Its action is focused on providing a physical barrier to protect the ulcer from further damage.

C) "This medication neutralizes gastric acid after it is secreted":
Neutralizing gastric acid is the role of antacids, not sucralfate. Sucralfate acts by adhering to the ulcer site and forming a protective layer, which is distinct from the mechanism of neutralizing acid after secretion.

D) "This medication adheres to the ulcer and protects it from gastric acid":
Sucralfate forms a protective barrier over ulcers by adhering to the ulcer surface. This adherence helps to shield the ulcer from gastric acid and other digestive juices, promoting healing by creating an environment conducive to tissue repair.
