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
Duchenne-Erb (Erb's) palsy is a type of brachial plexus injury that commonly results in an absent Moro reflex on the affected side, an extended arm at the elbow, and decreased grasp. These symptoms arise from injury to the fifth and sixth cervical nerves, leading to motor deficits.
Choice B rationale
This describes facial nerve palsy, not Erb's palsy. Facial nerve palsy affects the muscles of the face, leading to asymmetry during crying and drooping of the mouth's corner on the affected side.
Choice C rationale
While asymmetry of the Moro reflex is accurate, this choice incorrectly states that the arm is externally rotated and the grasp reflex is absent, which aligns more with a total brachial plexus injury rather than Erb's palsy.
Choice D rationale
Crepitus, no movement, swelling, and tenderness on palpation are indicative of a fracture rather than Erb's palsy. These symptoms suggest bone injury rather than nerve damage.
Correct Answer is B
Explanation
Choice A rationale
Feeding the newborn water during the procedure is incorrect because water does not provide effective pain relief during procedures.
Choice B rationale
Placing the newborn's arms and legs in flexion and close to the midline of the torso is correct as this position, known as facilitated tucking, provides comfort and can help reduce pain.
Choice C rationale
Placing the newborn supine during the procedure is incorrect because it does not provide any specific pain relief benefits.
Choice D rationale
Elevating the newborn's head during the procedure is not specifically related to pain relief but is more about positioning for ease of access. .
