The nurse is reviewing the laboratory results of a client who reports taking five times the recommended daily allowance of vitamins and minerals in a multivitamin form. Which finding indicates a possible vitamin D overdose?

Reference Range:

Bilirubin [0.3 to 1 mg/dL (5.1 to 17 μmol/L)]

Calcium 19 to 10.5 mg/dL (2.3 to 2.6 mmol/L)]

Sodium [136 to 145 mEq/L (136 to 145 mmol/L)]

Blood Glucose [74 to 106 mg/dL (4.1 to 5.9 mmol/L)]

Sodium level 140 mEq/L (140 mmol/L).

Total calcium level 12 mEq/L (3 mmol/L).

Total bilirubin 4 mg/dL (68.4 μmol/L).

Serum glucose 170 mg/dL (9.4 mmol/L).

Answer and Explanation

The Correct Answer is B

A) Sodium level 140 mEq/L (140 mmol/L):
The sodium level within the reference range does not indicate a vitamin D overdose. Sodium levels are typically not affected by vitamin D overdose.

B) Total calcium level 12 mg/dL (3 mmol/L):
This finding suggests a possible vitamin D overdose. Vitamin D plays a crucial role in calcium absorption from the intestines. Excessive vitamin D intake can lead to increased calcium absorption, resulting in hypercalcemia. Elevated calcium levels can lead to various symptoms such as nausea, vomiting, weakness, and confusion. Monitoring calcium levels is essential in individuals with suspected vitamin D overdose.

C) Total bilirubin 4 mg/dL (68.4 μmol/L):
Elevated bilirubin levels typically indicate liver dysfunction or hemolysis. It is not directly related to vitamin D overdose.

D) Serum glucose 170 mg/dL (9.4 mmol/L):
Elevated glucose levels suggest hyperglycemia, which can occur due to various factors such as diabetes mellitus or stress response. It is not directly related to vitamin D overdose.

Correct Answer is ["1.7"]

Explanation

To find out how many mL the nurse should administer:

We can set up a proportion to solve for the unknown.

Given:

The prescription is for 1,000,000 units of penicillin G.

The available medication is 1,200,000 units/2 mL.

We can set up the proportion as follows:

1,000,000units/ xmL = 1,200,000units/2mL

Solving for x gives us the volume in mL that the nurse should administer.

Cross-multiplying and solving for x:

X = 1,000,000units×2mL/1,200,000units

After performing the calculation, we find that x equals 1.67 mL.

So, the nurse should administer 1.7 mL (rounded to the nearest tenth) of the medication.

A. Keep an oral liquid or glucose source available. B. Check blood glucose levels every six hours. C. Assess for hypoglycemia between meals. D. Provide meals at the same time this insulin is given.

Correct Answer is D

Explanation

A) Keep an oral liquid or glucose source available:
While it's essential to have a readily available source of glucose in case of hypoglycemia, ensuring consistency in meal timing is more critical for managing blood sugar levels in clients receiving insulin lispro. However, having a glucose source available is still important as a precautionary measure.

B) Check blood glucose levels every six hours:
Frequent monitoring of blood glucose levels is essential in managing diabetes, but checking levels every six hours may not be necessary for all clients. The frequency of blood glucose monitoring should be individualized based on factors such as the client's overall glycemic control, insulin regimen, meal timing, and activity level.

C) Assess for hypoglycemia between meals:
While assessing for hypoglycemia is important, especially in clients receiving insulin therapy, ensuring consistent meal timing is a more proactive measure to prevent hypoglycemia. Clients should ideally consume meals or snacks containing carbohydrates around the same time they administer rapid-acting insulins like insulin lispro to prevent blood sugar fluctuations.

D) Provide meals at the same time this insulin is given:
This is the correct intervention. Insulin lispro is a rapid-acting insulin that is typically administered just before meals to control postprandial blood sugar levels effectively. Providing meals at consistent times relative to insulin administration helps synchronize the peak action of the insulin with the rise in blood glucose that occurs after eating, minimizing the risk of hypoglycemia and hyperglycemia.
