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. While a yearly dilated eye examination is crucial for the early detection and management of diabetic retinopathy, this action alone only addresses one of the two complications mentioned in the prompt. It does not prevent the development of nephropathy.

B. Examining the feet carefully every day is a vital preventive measure for diabetic neuropathy and peripheral vascular disease to avoid foot ulcers and infections. However, daily foot checks do not prevent microvascular damage to the eyes or kidneys.

C. Compression stockings are used to manage venous insufficiency or peripheral edema, but they are not standard preventative therapy for diabetic retinopathy or nephropathy, and tight hosiery may even be contraindicated if the client has co-existing peripheral arterial disease.

D. Maintaining stable, optimal blood glucose levels is the most effective primary intervention to prevent both retinopathy and nephropathy. Chronic hyperglycemia causes microvascular damage to the small blood vessels in both the retina and the renal glomeruli; therefore, strict glycemic control slows the onset and progression of both conditions simultaneously.

Correct Answer is ["A","B","D"]

Explanation

A. Tachycardia - This is an increased heart rate, which can occur in response to low blood sugar levels.

B. Moist clammy skin - Sweating and clamminess are common symptoms of hypoglycemia.

C. Polydipsia - This is excessive thirst, which is not typically a manifestation of hypoglycemia. It is more commonly associated with hyperglycemia (high blood sugar levels).

D. Blurred vision - This can occur when the eyes are not receiving enough glucose due to low blood sugar levels.

E. Polyuria - This is excessive urination, which is not typically a manifestation of hypoglycemia. It is more commonly associated with hyperglycemia.
