The healthcare provider prescribes 1 liter of lactate Ringer's to infuse in 8 hours. The IV administration set delivers 15 gtt/mL. How many mL/hour should the nurse program the infusion pump? (Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["125"]
Calculation:
- Convert the total volume from liters (L) to milliliters (mL).
Total volume = 1 L × 1000 mL/L
= 1000 mL.
Infusion time = 8 hours.
- Calculate the infusion rate in milliliters per hour (mL/hour).
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hour)
= 1000 mL / 8 hours
= 125 mL/hour.
Answer: 125

Correct Answer is B
Explanation
Rationale:
A. Place a foam surface on top of the mattress: A foam surface may help reduce pressure, but for a stage IV pressure injury with eschar, this alone is insufficient. More advanced pressure redistribution systems are needed for adequate management of severe wounds.
B. Raise the head of the bed only to 30 degrees: Limiting the head-of-bed elevation helps reduce shear forces, which worsen pressure injuries, especially over the sacrum. This intervention is critical for preventing further tissue damage and promoting healing of deep wounds with eschar.
C. Perform passive range of motion exercises: While passive ROM supports circulation and prevents contractures, it does not directly address pressure relief or eschar management. It's beneficial, but not the top priority for treating a stage IV ulcer.
D. Increase the daily intake of vitamin C: Vitamin C supports collagen synthesis and immune function, aiding wound healing. However, nutrition alone cannot address mechanical factors like pressure and shear, which are primary contributors to pressure injury progression.
Correct Answer is A
Explanation
Rationale:
A. Remind the UAP to apply a fitted respirator mask before entering the client's room:
Neisseria meningitidis is transmitted via respiratory droplets, and clients require droplet precautions. A fitted respirator mask is necessary when within 3 feet of the client.
B. Assign the UAP to provide care for another client and assume full care of the client:
Delegating tasks based on infection risk may be reasonable, but it's not necessary to reassign care if the UAP follows proper precautions.
C. Review the need for the UAP to wear a face mask while in close contact with the client: Education is essential but does not take priority over preventing immediate exposure. Ensuring protective equipment is worn first is more urgent than providing background instruction.
D. Instruct the UAP to notify the nurse of any changes in the client's emesis: Monitoring emesis is part of ongoing care but is not as urgent as preventing transmission of a highly contagious illness. Infection control measures must be enforced before other instructions.
