A nurse is preparing to infuse a 250-mL unit of packed RBCs over 2 hours. The drop factor of the manual IV tubing is 15 gtts/mL. The nurse should adjust the flow rate to deliver how many drops per minute?
(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 ["31"]
Step 1: Determine the total volume to be infused.
- Total volume = 250 mL
Step 2: Determine the total time for infusion in minutes.
- Total time = 2 hours
- Convert hours to minutes: 2 hours × 60 minutes/hour = 120 minutes
- Result: 120 minutes
Step 3: Determine the drop factor.
- Drop factor = 15 gtts/mL
Step 4: Calculate the flow rate in drops per minute.
- Flow rate (gtts/min) = (Total volume in mL × Drop factor) ÷ Total time in minutes
- Flow rate (gtts/min) = (250 mL × 15 gtts/mL) ÷ 120 minutes
- Result: (250 × 15) = 3750
- Result: 3750 ÷ 120 = 31.25
Step 5: Round the result to the nearest whole number.
- Rounded result: 31
Final Answer: The nurse should adjust the flow rate to deliver 31 drops per minute.

Correct Answer is C
Explanation
Choice A reason: Your baby will receive the first diphtheria, tetanus, pertussis vaccine at the 2-week well-baby visit is incorrect. The first dose of the diphtheria, tetanus, and pertussis (DTaP) vaccine is typically given at 2 months of age, not at 2 weeks.
Choice B reason: Your baby should receive the measles, mumps, rubella vaccine at 6 months is incorrect. The first dose of the measles, mumps, and rubella (MMR) vaccine is usually given at 12 to 15 months of age.
Choice C reason: Your baby will only receive the hepatitis B vaccine prior to discharge is correct. The hepatitis B vaccine is typically given within 24 hours of birth, and it is the only vaccine administered before the newborn is discharged from the hospital.
Choice D reason: Your baby should receive the pneumococcal conjugate vaccine on his first birthday is incorrect. The pneumococcal conjugate vaccine (PCV13) is given in a series of doses starting at 2 months of age, with additional doses at 4 months, 6 months, and a booster dose at 12 to 15 months.
Correct Answer is ["A","B","D","E"]
Explanation
Choice A reason: Apply intermittent ice to the affected ankle for the first 48 hours
Applying ice intermittently to the affected ankle for the first 48 hours helps reduce swelling and inflammation. Ice should be applied for 15-20 minutes every 2-3 hours during the initial phase of injury management. This practice is part of the RICE (Rest, Ice, Compression, Elevation) protocol commonly used for sprains and strains.
Choice B reason: Wrap the affected ankle with an elasticized compression bandage
Wrapping the affected ankle with an elasticized compression bandage helps to minimize swelling and provide support to the injured area. Compression bandages should be snug but not too tight to avoid restricting blood flow. This is another component of the RICE protocol.
Choice C reason: Apply full weight-bearing on the affected ankle
Applying full weight-bearing on the affected ankle is not recommended immediately after a second-degree sprain. The ankle needs time to heal, and weight-bearing should be gradually reintroduced as pain and swelling decrease. Initially, the client should avoid putting weight on the injured ankle to prevent further damage.
Choice D reason: Elevate the affected ankle above the level of the heart
Elevating the affected ankle above the level of the heart helps reduce swelling by promoting venous return and decreasing fluid accumulation in the injured area. This is an essential part of the RICE protocol and should be done as much as possible during the first 48 hours.
Choice E reason: Apply a heating pad intermittently to the affected ankle after 48 hours
Applying a heating pad intermittently to the affected ankle after 48 hours can help increase blood flow and promote healing. Heat therapy should be used after the initial acute phase (first 48 hours) when swelling has subsided. Heat can help relax muscles and reduce stiffness in the injured area.
