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?
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 C
Explanation
A. Checking the pedal pulses is important for assessing circulation, but it may not directly address the cause of the muscle spasms. In this case, addressing the electrolyte imbalance is a higher priority.
B. Requesting a relaxant might provide temporary relief for muscle spasms, but it does not address the potential underlying cause. It's important to identify and treat the root issue.
C. Correct. Severe muscle spasms in a client post-thyroidectomy could indicate hypocalcemia, as the parathyroid glands, which regulate calcium levels, can be affected during the surgery. Verifying the most recent calcium level will help determine if this is the cause.
D. Administering an oral potassium supplement addresses a different electrolyte imbalance (hypokalemia), which is not typically associated with muscle spasms following a thyroidectomy. Calcium levels are more relevant in this context.
Correct Answer is ["B","C"]
Explanation
A. NPH insulin may be mixed with pens. This statement is correct. NPH insulin can be mixed with other insulins, and it is available in pens for ease of administration.
B. Insulin detemir is administered once or twice daily, not necessarily with meals. Detemir is a long-acting insulin and can be taken once or twice daily, depending on the individual's specific treatment plan. It does not need to be strictly timed with meals.
C. Insulin glargine is a long-acting insulin and is generally not used as a first-line treatment for gestational diabetes. Short-acting insulins are typically recommended. Gestational diabetes is usually managed with short-acting insulins (like regular insulin) due to their faster onset and shorter duration of action. Long-acting insulins like glargine are not typically used in this context.
D. Regular insulin can be administered intravenously. This is a correct statement. Regular insulin can indeed be given intravenously in a hospital setting for precise control of blood glucose levels.
E. Lispro is a rapid-acting insulin. This statement is accurate. Lispro is a rapid-acting insulin analog used to control high blood sugar levels during and after meals. It has a fast onset of action.
