A nurse is reviewing a client's prescription for 1,000 ml of 5% dextrose in water IV to infuse over 8 hr. At 1400, the nurse observes that there is 500 ml of solution remaining in the client's current IV bag. At what time should the nurse administer the next bag of IV solution?
1700
1600
1500
1800
The Correct Answer is D
The total volume to infuse is 1,000 ml over 8 hours, which calculates to a rate of 125 ml/hour (1,000 ml ÷ 8 hr).
- By 1400, the client has already received 500 ml (since there is 500 ml remaining in the IV bag).
- The infusion has been running for 4 hours (from 1000 to 1400), which means the nurse has infused 500 ml (125 ml/hour × 4 hours).
- Since there are 500 ml remaining in the bag, it will take another 4 hours to complete the infusion (500 ml ÷ 125 ml/hour).
- Therefore, if the nurse administers the next bag immediately after the current one runs out, it will be at 1800 (1400 + 4 hours).
- However, the timing of administering the next bag depends on when the current bag will run out. Since there is still 500 ml remaining, it will take 4 more hours until the IV solution runs out, which is at 1800.

Correct Answer is C
Explanation
A. Having one nurse lift as the client pushes with his feet may not provide enough support and could potentially lead to an unsafe transfer, especially if the client is only partially able to assist.
B. Lifting the client under the shoulders with the assistance of another nurse may be appropriate for a different type of transfer, such as a sit-to-stand transfer, but it may not be the most suitable method for moving the client up in bed.
C. When a client is only partially able to assist, using a friction-reducing device, such as a slide or transfer board, is an effective and safe method. This device helps reduce the
friction between the client and the bed, making it easier to move the client up in bed.
D. Using a trapeze bar requires the client to have a certain level of strength and mobility, and may not be suitable for a client who is only partially able to assist.
Correct Answer is B
Explanation
A. A sheepskin heel pad is primarily used for pressure ulcer prevention, not for preventing plantar flexion contractures.
B. A footboard helps maintain the feet in a dorsiflexed position, preventing plantar flexion contractures in clients with impaired mobility. This device provides support and alignment to the lower extremities.
C. A trochanter roll is used to prevent external rotation of the hips and to maintain proper alignment. It is not specifically designed to prevent plantar flexion contractures.
D. An abduction pillow is used to maintain hip alignment and prevent hip adduction. It is not designed to address plantar flexion contractures.
