The patient's blood sugar level was 152 mg per dL at 1700 hr. How much insulin should be given using the following insulin sliding scale?
2 units.
3 units.
4 units.
5 units.
The Correct Answer is C
Choice A rationale
2 units is insufficient to bring down a blood sugar level of 152 mg/dL adequately. According to the sliding scale, 2 units typically lower blood sugar by 50-60 mg/dL, which might not be enough for this level.
Choice B rationale
3 units might reduce blood sugar by approximately 75-90 mg/dL. However, this reduction may not be adequate to bring the blood sugar level within the target range, depending on individual response to insulin.
Choice C rationale
4 units of insulin are suitable for a blood sugar level of 152 mg/dL. Generally, 1 unit of insulin lowers blood sugar by 30-50 mg/dL. Administering 4 units should ideally lower the blood sugar level to the desired range.
Choice D rationale
5 units of insulin could result in an excessive drop in blood sugar levels. It could reduce the blood sugar level by 150-200 mg/dL, which might risk hypoglycemia, making it an unsuitable choice for a blood sugar level of 152 mg/dL.

Correct Answer is A
Explanation
Choice A rationale
Car seats should not be purchased used as their history is unknown. There might be unseen damages or recalls that could compromise the safety of the infant.
Choice B rationale
The chest clip should be at the infant's armpit level, not shoulder level. Incorrect positioning can affect the restraint system's efficiency.
Choice C rationale
Infants should not wear coats in their car seats because bulky clothing can prevent the harness from fitting snugly, reducing its effectiveness in a crash.
Choice D rationale
Infant car seats should remain rear-facing until at least the age of 2 or until they reach the maximum weight/height limit of the seat, not turn forward-facing at the first birthday.
Correct Answer is B
Explanation
Choice A rationale
Checking the client's temperature every 4 hours is important to monitor for infection but is not the primary action during the active phase of labor following an amniotomy.
Choice B rationale
Encouraging the client to empty the bladder every 2 hours helps prevent bladder distention, which can impede the descent of the baby and contribute to labor progress.
Choice C rationale
Bearing down with each contraction is advised during the second stage of labor, not the active phase of the first stage.
Choice D rationale
Maintaining the client in the lithotomy position is not necessary throughout labor and can be uncomfortable; mobility and changing positions are encouraged.
