A nurse is assessing a client who has septic shock and is receiving dopamine by continuous IV infusion.
Which of the following findings indicates that the nurse should increase the rate of infusion?
Hypotension.
Extravasation.
Headache.
Chest pain.
The Correct Answer is A
Dopamine is a medication used to treat hypotension, low cardiac output, and poor perfusion of vital organs.
It is used to increase mean arterial pressure in septic shock patients who remain hypotensive after adequate volume expansion 1.
If the client is still experiencing hypotension while receiving dopamine by continuous IV infusion, the nurse should increase the rate of infusion to improve the client’s blood pressure.
Choice B is wrong because Extravasation, is not the correct answer because it refers to the leakage of IV fluid or medication into the surrounding tissue and is not an indication to increase the rate of dopamine infusion.
Choice C is wrong because Headache, is not the correct answer because it is not specifically related to dopamine therapy or an indication to increase the rate of infusion.
Choice D is wrong because Chest pain, is not the correct answer because it is not specifically related to dopamine therapy or an indication to increase the rate of infusion.

Correct Answer is C
Explanation
Metformin is an antidiabetic agent used to treat type 2 diabetes mellitus.
It works by decreasing carbohydrate absorption from the gut, increasing glucose uptake in peripheral tissues in the presence of insulin, and reducing hepatic gluconeogenesis.
In normal patients, metformin ingestion is not associated with hypoglycemia.
However, it is still important to check the client’s glucose level to ensure that it is within a safe range.
Choice A is wrong because collecting the client’s uric acid level is not necessary after accidental administration of metformin.
Choice B is wrong because obtaining the client’s HDL level is not necessary after accidental administration of metformin.
Choice D is wrong because monitoring the client’s thyroid function levels is not necessary after accidental administration of metformin.
Correct Answer is B
Explanation
Step 1: Convert weight from lb to kg.
88 lb ÷ 2.2 = 40 kg
Step 2: Calculate total daily dose in mg.
150 mg/kg × 40 kg = 6000 mg
Step 3: Calculate dose per administration (every 6 hr).
6000 mg ÷ 4 = 1500 mg
Step 4: Calculate number of tablets per dose.
1500 mg ÷ 500 mg/tab = 3 tablets
Answer:
3 tablets per dose.
