The primary health-care provider prescribes a cough syrup 0.4 g every 4 hours. The dosage strength of the syrup is 100 mg/5 mL. The medication bottle contains a measuring spoon that measures in teaspoons and tablespoons. How many teaspoons will the nurse instruct the client to take?
Answer and Explanation

The Correct Answer is ["4"]

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.

  • 4×5 mL=20 mL

  • 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 B

Explanation

A. This option corresponds to the blood glucose range of 151-200. However, the patient's current blood glucose level is 264, which falls into the range of 251-300. Therefore, administering 2 units would not be appropriate in this case.

B. The patient's current blood glucose level is 264, which falls into the range of 251-300. According to the sliding scale insulin aspart orders, for this range, 6 units should be administered. This option aligns with the patient's blood glucose level and the prescribed protocol.

C. This option corresponds to the blood glucose range of 351-400. The patient's blood glucose level of 264 does not fall into this range, so administering 10 units would be excessive and potentially lead to hypoglycemia.

D. This option corresponds to the blood glucose range of 201-250. The patient's current blood glucose level is 264, which falls into the range of 251-300. Therefore, administering 4 units would not be sufficient to address the elevated blood glucose level.

Correct Answer is C

Explanation

A. Incorrect. Aging is associated with a decrease in insulin production and a reduction in the speed of insulin release, not an increase.

B. Incorrect. Intolerance of fatty foods is not typically an age-related endocrine change. It may be related to other factors such as digestive issues.

C. Correct. Decreased sensitivity to insulin is a common age-related endocrine change, particularly in individuals with type 2 diabetes mellitus.

D. Incorrect. Lower and prolonged blood glucose levels are not an expected age-related endocrine change. Instead, insulin resistance tends to result in elevated blood glucose levels.
