A nurse is reviewing the plan of care with a client who has a new prescription for lovastatin. Which of the following statements by the client should indicate to the nurse a need for further assessment?

"I should avoid drinking grapefruit juice."

"I am trying to decrease my dietary fat intake."

"I was just diagnosed with hepatitis B."

"I take metformin for my diabetes."

Answer and Explanation

The Correct Answer is C

Choice A Reason:
"I should avoid drinking grapefruit juice." This statement is actually accurate. Grapefruit juice can interfere with the metabolism of certain statin medications, including lovastatin, leading to increased levels of the drug in the body. Advising against grapefruit juice consumption is a recommended precaution when taking lovastatin, so this statement shows the client's understanding of this interaction.
Choice B Reason:
"I am trying to decrease my dietary fat intake." This statement reflects a positive lifestyle change. Lowering dietary fat intake is often recommended for individuals on statin medications to help manage cholesterol levels. This statement demonstrates the client's commitment to making healthy dietary adjustments, which aligns with the treatment plan.
Choice B Reason:
"I was just diagnosed with hepatitis B. "Hepatitis B can affect liver function, and statin medications like lovastatin can potentially impact liver enzymes. Therefore, in someone with a history of hepatitis B, it's crucial to assess liver function before starting a statin and to monitor the liver during treatment. This statement raises concerns about potential liver complications or interactions that require further evaluation before initiating lovastatin.
Choice D Reason:
"I take metformin for my diabetes." Metformin, a medication for diabetes, does not directly interact with lovastatin. While it's relevant to know the client's other medications, this statement doesn't indicate a need for immediate further assessment regarding the use of lovastatin.

Correct Answer is A

Explanation

Choice A Reason:
"You should monitor for hearing difficulties." is correct. Loop diuretics like bumetanide can occasionally cause ototoxicity, resulting in hearing difficulties or ringing in the ears (tinnitus) as a potential adverse effect. It's important for clients taking these medications to be aware of such symptoms and report them promptly to their healthcare provider.
Choice B Reason:
"You should take the medication at bedtime." Is incorrect. Bumetanide is commonly prescribed to be taken in the morning to avoid nighttime diuresis and potential sleep disruption due to increased urination.
Choice C Reason:
"You should decrease your intake of foods high in potassium." Is incorrect. Loop diuretics often lead to potassium loss, so clients may actually need to increase their intake of potassium-rich foods or take potassium supplements under healthcare provider guidance to maintain normal potassium levels.
Choice D Reason:
"You should take this medication on an empty stomach." Is incorrect. Bumetanide can be taken with or without food, so it's not necessary to take it on an empty stomach.

Correct Answer is ["60"]

Explanation

Step 1: Determine the Lidocaine Concentration

The solution contains 2 grams (2000 mg) of lidocaine in 500 mL.
To find the amount of lidocaine per mL:
2000 mg ÷ 500 mL = 4 mg/mL

Step 2: Calculate the Total Dose per Hour

The prescribed infusion rate is 4 mg per minute.
In 1 hour (60 minutes), the total dose is:
4 mg/min × 60 min = 240 mg/hr

Step 3: Determine the Infusion Rate in mL/hr

Since each mL contains 4 mg of lidocaine:
240 mg ÷ 4 mg/mL = 60 mL/hr

The nurse should set the IV pump to 60 mL/hr for the continuous IV infusion of lidocaine at a rate of 4 mg/min.
