A nurse is caring for a client who has recurrent kidney stones and a history of diabetes mellitus.
The client is scheduled for an intravenous Pyelogram (IVP). The nurse should collect additional data about which of the following statements made by the client?

“I haven’t had anything to eat or drink since last night.”

“The last time I voided it was painful.”

“I took my metformin before breakfast.”

“I took a laxative yesterday.”

Answer and Explanation

The Correct Answer is C

Choice A rationale:

The client stating, “I haven’t had anything to eat or drink since last night” is not a cause for concern. This is because patients are often advised to fast before undergoing certain medical procedures or tests, including an intravenous pyelogram (IVP).

Fasting helps to ensure that the test results are accurate and not influenced by recent food or drink consumption.

Choice B rationale:

The client expressing that “The last time I voided it was painful” could be related to their recurrent kidney stones. Kidney stones can cause discomfort or pain during urination. However, this statement does not necessarily require additional data collection in the context of an IVP. The pain could be a symptom of the kidney stones rather than a contraindication for the IVP1.

Choice C rationale:

The statement “I took my metformin before breakfast” is of concern. Metformin is a medication used to treat type 2 diabetes. It is important for the nurse to collect additional data about this statement because metformin can potentially interact with the iodine-based contrast dye used in an IVP. This interaction can increase the risk of lactic acidosis, a serious and potentially lifethreatening condition. Therefore, patients are often advised to stop taking metformin before and for a couple of days after having an IVP12. Choice D rationale:

The client mentioning, “I took a laxative yesterday” is not necessarily alarming. Laxatives are often used before an IVP to clear the bowels, which helps to ensure clear images during the procedure. Therefore, this statement does not require additional data collection in the context of an IVP1.

Correct Answer is ["2"]

Explanation

Let’s solve the medication math problem step by step:

Step 1: Identify the total daily dose of amoxicillin. The total daily dose is 2 gm/day.

Step 2: Convert the total daily dose from grams to milligrams, as the available medication is in milligrams. We know that 1 gm = 1000 mg, so 2 gm = 2000 mg.

Step 3: The total daily dose is divided into two doses. So, each dose will be 2000 mg ÷ 2 = 1000 mg.

Step 4: Determine the number of tablets for each dose. Each tablet contains 500 mg of amoxicillin. So, the number of tablets for each dose is 1000 mg ÷ 500 mg/tablet = 2 tablets.

So, the nurse should administer 2 tablets of amoxicillin with each dose.

A. The safe and the toxic plasma levels of the drug are very close to each other. B. The phenytoin has a low chance of being effective. C. There is no difference between safe and toxic plasma levels. D. A very small dosage can result in the desired therapeutic effect. E. A very small dosage can result in the desired therapeutic effect.

Correct Answer is A

Explanation

Choice A rationale:

Phenytoin is an anticonvulsant drug used in the prophylaxis and control of various types of seizures. It has a narrow therapeutic index, which means that the safe and toxic plasma levels of the drug are very close to each other. This characteristic makes the dosing of phenytoin challenging, as even small deviations from the recommended therapeutic range can lead to suboptimal treatment or adverse effects. Therapeutic effect without clinical signs of toxicity occurs more often with serum total concentrations between 10 and 20 mcg/mL34. Therefore, clinicians are advised to initiate therapeutic drug monitoring in patients who require phenytoin.

Choice B rationale:

The statement that phenytoin has a low chance of being effective is incorrect. Phenytoin is a widely used and effective anticonvulsant. It works by slowing down impulses in the brain that cause seizures. It is used to control seizures but does not treat all types of seizures. The effectiveness of phenytoin is not determined by its narrow therapeutic index but by its pharmacological action in the brain.

Choice C rationale:

The assertion that there is no difference between safe and toxic plasma levels of phenytoin is incorrect. There is indeed a difference between the safe (therapeutic) and toxic levels of phenytoin. The therapeutic range for phenytoin is typically between 10 and 20 mcg/mL34. Levels above this range can lead to toxicity, while levels below this range may not provide the desired therapeutic effect.

Choice D rationale:

The statement that a very small dosage of phenytoin can result in the desired therapeutic effect is not entirely accurate. While it’s true that phenytoin is effective in controlling seizures, the dosage required to achieve this effect is not necessarily “very small”. The usual adult dose for seizures is 100 mg orally 3 times a day. The dosage may need to be adjusted based on individual patient factors and response to therapy. Therefore, it’s not accurate to generalize that a “very small” dosage will result in the desired therapeutic effect for all patients.
