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.

Answer and Explanation

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

Painless, bright red vaginal bleeding at 36 weeks gestation is a classic sign of placenta previa, where the placenta is abnormally implanted in the lower uterine segment, covering the cervix, and causing bleeding without pain.

Choice B rationale

Threatened abortion is characterized by vaginal bleeding before 20 weeks of gestation with or without abdominal pain. At 36 weeks, the term would be inappropriate, and the symptoms do not match.

Choice C rationale

Abruptio placentae involves painful vaginal bleeding due to premature placental separation. The presence of pain differentiates it from placenta previa.

Choice D rationale

Preterm labor may present with contractions, cervical changes, and possible bleeding, but the key feature distinguishing it from placenta previa is the presence of uterine contractions and pain, which are absent in this scenario.

A. Need for increased insulin dosage in the first trimester. B. Development of hypotension. C. Weight gain higher than recommended. D. Polyphagia.

Correct Answer is D

Explanation

Choice A rationale

In pregestational type 1 diabetes mellitus, insulin needs typically decrease during the first trimester due to increased insulin sensitivity and decreased food intake from nausea and vomiting, not an increased dosage.

Choice B rationale

Hypotension is not a typical finding associated with pregestational type 1 diabetes mellitus. Instead, hyperglycemia and its complications, such as ketoacidosis, are more relevant concerns.

Choice C rationale

While weight gain is monitored in diabetic pregnancies, excessive weight gain is not a specific condition associated with pregestational type 1 diabetes mellitus. Weight management should be appropriate to avoid complications.

Choice D rationale

Polyphagia, or increased hunger, is a symptom associated with diabetes mellitus due to the body's inability to properly utilize glucose, leading to increased appetite and higher blood glucose levels.
