A nurse is assisting with the care of a client who has hyperemesis gravidarum and is receiving 0.9% sodium chloride 1,000 mL IV to infuse over 8 hr. The nurse should ensure that the IV pump is set to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["125"]
Given:
Total volume to be infused: 1,000 mL
Infusion time: 8 hours
Step 1: Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Step 2: Substitute the values:
Infusion rate (mL/hr) = 1,000 mL / 8 hr
Step 3: Calculate the infusion rate:
Infusion rate (mL/hr) = 125 mL/hr

Explanation
Given:
Desired dose of cephalexin: 250 mg
Concentration of cephalexin tablets: 500 mg/tablet

Number of tablets = Desired dose (mg) / Concentration per tablet (mg/tablet)
Number of tablets = 250 mg / 500 mg/tablet
Number of tablets = 0.5 tablets
Correct Answer is ["1.3"]
Explanation
Given:
Desired dose of procaine penicillin: 800,000 units
Concentration of procaine penicillin suspension: 600,000 units/mL
Step 1: Set up the proportion:
Desired dose (units) / Volume to administer (mL) = Concentration (units/mL)
Step 2: Substitute the values:
800,000 units / Volume = 600,000 units/mL
Step 3: Solve for the unknown volume:
Volume = 800,000 units / 600,000 units/mL
Step 4: Calculate the volume:
Volume = 1.333333333 mL
Step 5: Round to the nearest tenth:
Volume ≈ 1.3 mL
