A nurse is calculating the fluid intake for an infant at the end of an 8-hr shift. For oral intake, the infant had 10 mL of medication, 3 oz of formula, and 2 oz of juice. In addition, the infant had IV fluid infusing at 20 mL/hr via an IV pump. The nurse should record how many mL of intake on the clients record? (Round the answer to the nearest whole number.)
310 mL
390 mL
320 mL
180 mL
The Correct Answer is C
To calculate:
1. Convert units:
1 oz = 30 mL
3 oz formula = 3 oz x 30 mL/oz = 90 mL
2 oz juice = 2 oz x 30 mL/oz = 60 mL
2. Calculate total oral intake:
Total oral intake = 10 mL (medication) + 90 mL (formula) + 60 mL (juice) = 160 mL
3. Calculate IV fluid intake:
IV fluid intake = 20 mL/hr x 8 hr = 160 mL
4. Calculate total fluid intake:
Total fluid intake = 160 mL (oral) + 160 mL (IV) = 320 mL
Answer: 320 mL

Correct Answer is D
Explanation
Identify the desired dose and the available concentration:
Desired dose: 5 mg of hydrocodone
Available concentration: 7.5 mg of hydrocodone in 15 mL of elixir
Calculate the volume needed for the desired dose using the formula:
Volume(mL)=(Desireddose(mg)/Availableconcentration(mg/mL))
Determine the available concentration in mg/mL:
Availableconcentration=(7.5mg/15mL)=0.5mg/mL
Calculate the volume needed for a 5 mg dose:
Volume(mL)=(5mg/0.5mg/mL)=10mL
Correct Answer is A
Explanation
Given:
Infusion rate: 3 mL/hr
Concentration of Nitroglycerin: 50 mg in 250 mL D5W (200 mcg/mL)
Step 1: Calculate the dose in mg/hr:
Dose (mg/hr) = Infusion rate (mL/hr) x Concentration (mg/mL)
Dose (mg/hr) = 3 mL/hr x 200 mcg/mL
Dose (mg/hr) = 600 mcg/hr
