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 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.
Correct Answer is C
Explanation
Choice A rationale
An increase in serum bilirubin levels indicates worsening hyperbilirubinemia rather than improvement. Effective phototherapy should result in a decrease in bilirubin levels as it helps break down bilirubin into a form that can be excreted.
Choice B rationale
Hemoglobin and hematocrit levels are not directly affected by phototherapy. These values are more related to red blood cell count and do not indicate the effectiveness of phototherapy for treating hyperbilirubinemia.
Choice C rationale
A decrease in transcutaneous bilirubin (TcB) levels from 6 hours ago indicates effective phototherapy. Phototherapy reduces bilirubin levels in the blood by converting it to a water-soluble form that can be eliminated from the body.
Choice D rationale
Jaundice typically moves from the head to the lower body as bilirubin levels decrease. Movement from chest to groin level without a corresponding decrease in bilirubin levels does not necessarily indicate effective phototherapy. .
