A nurse is preparing to administer medication to a preschooler and must convert the child's weight from pounds to kilograms. The child weighs 30 lb. How many kilograms does the child weigh?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

The correct answer is choice b. Three-point.

Choice A rationale:

The four-point gait is used when a client can bear weight on both legs. It involves moving one crutch forward, followed by the opposite leg, then the other crutch, and finally the other leg. This gait provides maximum stability but is not suitable for non-weight-bearing conditions.

Choice B rationale:

The three-point gait is appropriate for clients who cannot bear weight on one leg. In this gait, both crutches and the affected leg move forward together, followed by the unaffected leg. This allows the client to keep weight off the injured leg while moving.

Choice C rationale:

The two-point gait is used when a client can bear partial weight on both legs. It involves moving one crutch and the opposite leg forward simultaneously, followed by the other crutch and leg. This gait is faster than the four-point gait but still provides some stability.

Choice D rationale:

The swing-through gait is used by clients who have good upper body strength and balance. It involves moving both crutches forward together and then swinging both legs forward past the crutches. This gait is not typically recommended for clients who need to keep weight off one leg.

The correct answer is Choice C: Take vitamin D supplements.

Choice A rationale:

Reducing intake of calcium-rich foods would not be a suitable recommendation. Calcium is essential for bone health, and a client with minimal sunlight exposure is at risk of vitamin D deficiency, which affects calcium absorption. Therefore, this choice would worsen the client's situation.

Choice B rationale:

Using sunscreen with an SPF of 8 is unlikely to provide adequate protection against the harmful effects of sunlight. Moreover, the client's issue is vitamin D deficiency due to minimal sunlight exposure, and using sunscreen would further hinder vitamin D synthesis.

Choice C rationale:

Taking vitamin D supplements is the most appropriate intervention. Vitamin D is synthesized in the skin upon exposure to sunlight, and since the client has minimal sunlight exposure, supplements are necessary to prevent vitamin D deficiency. This choice addresses the root cause of the issue.

Choice D rationale:

Using a tanning bed is not recommended for increasing vitamin D levels. Tanning beds emit ultraviolet (UV) radiation, which can increase the risk of skin cancer. Moreover, excessive UV exposure is not a safe or controlled method for addressing vitamin D deficiency.
