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 D

Explanation

A. NPH insulin: NPH insulin, also known as Neutral Protamine Hagedorn, is an intermediate acting insulin. It has a slower onset of action and a longer duration compared to regular insulin. It is not the best choice for treating diabetic ketoacidosis (DKA) because it does not act quickly enough to lower dangerously high blood glucose levels in this acute situation.

B. Insulin glargine: Insulin glargine is a long-acting basal insulin. It has a slow, steady release and provides a consistent level of insulin over an extended period. Like NPH insulin, it is not suitable for rapidly lowering blood glucose levels in a DKA emergency.

C. Insulin detemir: Insulin detemir is another long-acting basal insulin similar to glargine. It has a slow onset and provides a sustained release of insulin. It is not the first-line choice for treating DKA due to its slower action.

D. Regular Insulin: Regular insulin, also known as short-acting or fast-acting insulin, has a rapid onset of action. When administered intravenously, it can quickly lower blood glucose levels. This makes it the preferred choice for treating diabetic ketoacidosis (DKA) where prompt action is essential to correct the severe hyperglycemia and associated metabolic imbalances.

Correct Answer is B

Explanation

A. Obtaining a culture of the drainage may be necessary, but the immediate concern is to determine if the drainage is cerebrospinal fluid (CSF) or another type of fluid. Checking for glucose content is a rapid way to differentiate CSF from other fluids.

B. Correct. Clear drainage from the nose post-transsphenoidal hypophysectomy may indicate a CSF leak, which is a potential complication. Checking the drainage for glucose can help differentiate CSF from other fluids, as CSF contains glucose. If the drainage tests positive for glucose, it indicates the presence of CSF.

C. Documenting the amount of drainage is important, but determining the nature of the drainage (CSF or other fluid) takes precedence in this situation.

D. Notifying the client's provider is important, but the nurse should gather information about the drainage first by checking for glucose content. This information will be crucial for the healthcare provider to make decisions about further interventions
