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) The client should use an electric razor while on this medication:
Warfarin is an anticoagulant that increases the risk of bleeding. Using an electric razor instead of a manual razor reduces the risk of cuts and bleeding while shaving, which is important to minimize bleeding complications associated with warfarin therapy.

B) Warfarin increases the risk for deep vein thrombosis:
Warfarin actually decreases the risk of deep vein thrombosis (DVT) and other blood clotting disorders by inhibiting the production of clotting factors. It is used to prevent and treat blood clots, not increase their risk.

C) Nose bleeds are common during initial treatment:
While bleeding is a potential side effect of warfarin therapy, nosebleeds specifically are not more common during initial treatment compared to later phases of therapy. Any bleeding should be reported to the healthcare provider for assessment and management.

D) If he misses a dose, he should double the dose at the next scheduled time:
Doubling the dose of warfarin can increase the risk of bleeding due to excessive anticoagulation. If a dose is missed, the client should take it as soon as they remember unless it is close to the time for the next scheduled dose, in which case they should skip the missed dose and continue with the regular schedule.

A. Chill the otic solution prior to administration. B. Pull the pinna upward and backward. C. Avoid applying pressure to the tragus of the ear. D. Don sterile gloves to instill the medication.

Correct Answer is B

Explanation

A) Chill the otic solution prior to administration:
Chilling ear drops is not typically necessary or recommended. Cold solutions can cause discomfort or dizziness when instilled into the ear. Room temperature or slightly warmed ear drops are generally more comfortable for the client.

B) Pull the pinna upward and backward:
This is the correct action for administering ear drops to an adult client. Pulling the pinna (outer ear) upward and backward helps straighten the ear canal, allowing the drops to enter the ear canal properly.

C) Avoid applying pressure to the tragus of the ear:
The tragus is the small cartilaginous flap in front of the ear canal. Applying pressure to the tragus can help facilitate the flow of medication into the ear canal rather than avoiding it. Gently pressing on the tragus after instilling the drops can aid in distributing the medication.

D) Don sterile gloves to instill the medication:
Sterile gloves are not typically required for administering ear drops unless the nurse is dealing with a client with a compromised immune system or open ear canal. Standard precautions (clean hands) are usually sufficient for administering ear drops.
