Question 1 of 5
A nurse is preparing to administer filgrastim 5 mcg/kg/day subcutaneous to a client who weighs 143 lb. How many mcg should the nurse administer per day? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the dose of filgrastim for the client, first convert the weight from pounds to kilograms. 143 lb / 2.2 = 65 kg.
Then, multiply the weight in kg by the dosage of 5 mcg/kg/day. 65 kg * 5 mcg/kg/day = 325 mcg/day.
Therefore, the correct answer is A: 325 mcg/day.
Choices B, C, and D are incorrect because they do not accurately calculate the dose based on the client's weight and the prescribed dosage.
Question 2 of 5
A home care nurse is teaching a client about safe medication disposal. Which of the following instructions should the nurse include?
Correct Answer: D
Rationale:
Rationale:
Choice D is correct because returning expired medication to the pharmacist ensures proper disposal, preventing environmental harm and misuse.
Choice A is incorrect as it can lead to accidental ingestion.
Choice B is incorrect as it can contaminate water sources.
Choice C is incorrect as it can harm aquatic life.
Question 3 of 5
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?
Correct Answer: B
Rationale: The correct answer is B: Hypotension. In septic shock, hypotension is a common sign of inadequate tissue perfusion. Dopamine is a vasopressor that helps increase blood pressure by constricting blood vessels.
Therefore, if the client is still hypotensive despite receiving dopamine, it indicates that the current infusion rate is not sufficient to maintain adequate perfusion. Increasing the infusion rate can help improve blood pressure and perfusion.
Incorrect choices:
A: Headache - Not a direct indication of dopamine infusion rate adjustment.
C: Chest pain - Not a direct indication of dopamine infusion rate adjustment.
D: Extravasation - Indicates leakage of medication from the IV site, not a need to adjust infusion rate.
Question 4 of 5
A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 ml- via intermittent IV bolus over 30 min. The drop factor of the manual IV tubing is I5 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the IV infusion rate, first, convert the infusion time to minutes (30 min).
Then, calculate the total volume to be infused (100 mL). Next, determine the total number of drops needed (15 gtt/mL x 100 mL) = 1500 drops. Finally, divide the total drops by the infusion time in minutes (1500 drops / 30 min) = 50 gtt/min. This is why choice A (50) is correct.
Choices B, C, and D are incorrect as they do not match the calculated infusion rate.
Question 5 of 5
A nurse is assessing a client who is taking phenelzine and reports eating aged cheese. Which of the following is a manifestation of an interaction between the medication and the food?
Correct Answer: D
Rationale: The correct answer is D: Hypertension. Phenelzine is a monoamine oxidase inhibitor (MAOI) that can interact with tyramine-rich foods like aged cheese, leading to hypertensive crisis. Tyramine can displace norepinephrine, causing a sudden increase in blood pressure. Somnolence (choice
A) is a common side effect of phenelzine but not related to the interaction with aged cheese. Diarrhea (choice
B) is not a typical manifestation of this interaction. Bradycardia (choice
C) is not associated with the MAOI and aged cheese interaction.
