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 is not ideal for levothyroxine (Synthroid) because it should be taken on an empty stomach for optimal absorption. Taking it with food, especially a meal like breakfast, can interfere with its absorption.

B. This is the correct option. Levothyroxine should be taken in the morning, at least 30 minutes before breakfast, or any other medications. Taking it on an empty stomach ensures the best absorption of the medication.

C. Taking levothyroxine in the evening is not recommended. It should be taken in the morning to coincide with the body's natural circadian rhythm and to avoid potential interactions with food or other medications.

D. While it's important to take levothyroxine in the morning before breakfast, it is not necessary to take it without any other medications. It can be taken alongside other daily medications as long as there are no interactions that would affect its absorption.

Correct Answer is C

Explanation

A. Flaccid muscles are associated with conditions like hypokalemia, not hypoparathyroidism. In hypoparathyroidism, there is a deficiency of parathyroid hormone (PTH), which leads to low calcium levels and can result in muscle spasms and tetany, not flaccid muscles.

B. While anorexia can occur in clients with various health conditions, it is not a specific finding associated with hypoparathyroidism.

C. Correct. Hypoparathyroidism is characterized by low levels of parathyroid hormone (PTH), which leads to low calcium levels in the blood. This can cause symptoms such as numbness, tingling, and muscle cramps, especially in the extremities.

D. A positive Chvostek's sign is associated with hypocalcemia, which can be caused by hypoparathyroidism. Therefore, a negative Chvostek's sign would not be an expected finding in a client with hypoparathyroidism.
