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

Answer and Explanation

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 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.

A. Instruct the client to tighten muscle groups for a short period, then relax. B. Move the client's limbs through their complete range of motion. C. Ask the client to move her arms and legs while applying slight resistance. D. Have the client move each limb independently through its complete range of motion.

Correct Answer is A

Explanation

A. Isometric exercises involve contracting or tensing muscles without actually moving the joint. Instructing the client to tighten muscle groups for a short period and then relax is the correct approach for isometric exercises. This action helps activate and strengthen specific muscle groups without moving the joints.
B. Moving the client's limbs through their complete range of motion is known as passive range of motion exercises. These exercises are important for maintaining joint flexibility but are not isometric.
C. Asking the client to move her arms and legs while applying slight resistance is known as resisted range of motion exercises. These exercises involve active movement against resistance and are not considered isometric.
D. Having the client move each limb independently through its complete range of motion is known as active range of motion exercises. These exercises involve voluntary
movement of each joint through its full range of motion and is not isometric.
