Question 1 of 5
A nurse is calculating a client's fluid intake over the past 8 hr. The client had one 8-oz cup of coffee, 3 oz of juice, and 12 oz of soda. The client's water pitcher had 800 mL and 200 mL remain. The client also had IV fluids infusing at 40 mL/hr via an IV pump. How many mL should the nurse document as the client's total intake for the shift?
Correct Answer: C
Rationale: The correct answer is C: 1600 mL.
To calculate total intake, add up all sources: 8 oz coffee = 240 mL, 3 oz juice = 90 mL, 12 oz soda = 360 mL, remaining water in pitcher = 200 mL, total oral intake = 240 + 90 + 360 + 200 = 890 mL. IV fluids at 40 mL/hr for 8 hours = 320 mL.
Total intake = 890 mL + 320 mL = 1210 mL. So, the nurse should document 1210 mL oral intake + 400 mL IV fluids = 1600 mL total intake. Other choices are incorrect as they do not accurately calculate the total intake.
Question 2 of 5
Calculate the flow rate in mL/hr. and Units/hr. (Equipment used is programmable in whole mL/hr and Show all work) Order: 100 mL 0.45% NS in 45 min by infusion pump. Calculate rate in ml/hr
Correct Answer: A
Rationale:
To calculate the flow rate in mL/hr, we first convert 45 min to hours by dividing by 60 (45 min / 60 min/hr = 0.75 hr).
Then, we divide the total volume to be infused (100 mL) by the time in hours (0.75 hr) to get the flow rate in mL/hr: 100 mL / 0.75 hr = 133 mL/hr.
Therefore, the correct answer is A. Option B is incorrect as it is one-tenth of the correct value. Option C is incorrect as it is close but not the exact calculation. Option D is incorrect as it is also one-tenth of the correct value.
Question 3 of 5
Convert the following metric measures to kg by moving the decimal: 5,524 g
Correct Answer: A
Rationale: The correct answer is A: 5.524 kg.
To convert grams to kilograms, divide by 1000 since there are 1000 grams in 1 kilogram.
Therefore, 5,524 g ÷ 1000 = 5.524 kg.
Choice B is incorrect because it incorrectly moves the decimal two places to the left.
Choice C is incorrect as it moves the decimal one place too many to the right.
Choice D is incorrect as it adds unnecessary zeros after the decimal point.
Question 4 of 5
What factors affect physiological response to drug use?
Correct Answer: A
Rationale: The correct answer is A (Age, weight, and sex). Physiological response to drug use is influenced by these factors because they affect metabolism, distribution, and elimination of drugs in the body. Age can alter enzyme activity, weight can impact drug distribution in body tissues, and sex differences can affect drug metabolism. Marital status and family history (
B), diet and exercise (
C), and socioeconomic status and education level (
D) do not directly influence physiological response to drug use. These factors may have indirect effects on drug use behaviors but do not directly impact how the body responds to drugs.
Question 5 of 5
A nurse is assisting with care of a cient who has a prescription for 3000 ml of intravenous huias over the nes:24 hr The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number)
Correct Answer: A
Rationale:
To calculate the IV rate, divide the total volume by the total hours: 3000 ml / 24 hr = 125 mL/hr.
Choice A is correct as it accurately calculates the hourly rate of IV fluids.
Choice B, 30 mL/hr, is incorrect as it does not divide 3000 ml by 24 hr.
Choice C, 100 mL/hr, is incorrect as it does not calculate the correct division of volume by time.
Choice D, 12.5 mL/hr, is incorrect as it miscalculates the rate.
