The client with type 1 diabetes mellitus is prescribed to take NPH (Humulin N) insulin at 5 PM each day. The client should be instructed that the greatest risk of hypoglycemia will occur about what time?

A.

1AM while sleeping

B.

PM shortly after lunch

C.

6 PM shortly after dinner

D.

11:00 AM, shortly before lunch

Answer and Explanation

The Correct Answer is A

1 AM while sleeping: NPH insulin, like Humulin N, typically reaches its peak effectiveness  about 4-12 hours after administration. Since the client takes it at 5 PM, the time of greatest risk  for hypoglycemia is around 1 AM when the insulin's effects are at their peak. This is a critical  period for monitoring blood glucose levels.

B. 8 PM shortly after dinner: By 8 PM, the NPH insulin's effectiveness is not at its peak. It's been  about 3 hours since administration, and the insulin is still working to lower blood glucose levels.  This time frame is not associated with the highest risk of hypoglycemia. 

C. 6 PM shortly after dinner: At 6 PM, it's been only about an hour since the client took the NPH  insulin. The insulin is just beginning to take effect, and the risk of hypoglycemia is not as high as  it would be later in the night. 

D. 11:00 AM, shortly before lunch: By 11:00 AM, the effects of the NPH insulin from the  previous evening have largely worn off. This time frame is not associated with a high risk of  hypoglycemia related to the evening dose of NPH insulin.

Explanation

Step 1: Convert the Prescribed Dose to Milligrams

The prescribed dose is 0.4 grams (g), but the medication strength is in milligrams (mg). We need to use the same unit for both.

  • There are 1000 mg in 1 g.

  • To convert 0.4 g to mg, we multiply by 1000.

  • 0.4×1000=400

  • The prescribed dose is 400 mg.

Step 2: Calculate the Volume (in mL) Needed for the Dose

We know that 5 mL of the syrup contains 100 mg of medication. We need to find out how many mL are needed for 400 mg.

  • To find out how many groups of 100 mg are in 400 mg, we divide:

  • 400÷100=4

  • This means we need 4 times the volume of syrup that contains 100 mg.

  • The volume for 100 mg is 5 mL. So, we multiply 4 by 5 mL.

  • 4×5mL=20mL

  • The total volume needed per dose is 20 mL.

Step 3: Convert the Volume to Teaspoons

The measuring spoon is in teaspoons (tsp). We need to convert 20 mL to teaspoons.

  • There are 5 mL in 1 teaspoon.

  • To find out how many teaspoons are in 20 mL, we divide 20 by 5.

  • 20÷5=4

  • The dose is 4 teaspoons.

The nurse will instruct the client to take 4 teaspoons.

Correct Answer is ["4"]

Explanation

One gram is equal to 1000 milligrams, one milliliter is equal to 0.2 teaspoons, and one teaspoon is equal to 5 milliliters. Using these conversion factors, the nurse can perform the following steps:

- Multiply the prescribed amount of cough syrup by 1000 to get the equivalent in milligrams: 0.4 g x 1000 = 400 mg

- Divide the equivalent in milligrams by the dosage strength of the syrup to get the equivalent in milliliters: 400 mg / 100 mg/5 mL = 20 mL

- Multiply the equivalent in milliliters by 0.2 to get the equivalent in teaspoons: 20 mL x 0.2 = 4 teaspoons

Therefore, the nurse will instruct the client to take 4 teaspoons of cough syrup every 4 hours.
