The nurse is administering liquid medications through a percutaneous endoscopic gastrostomy (PEG) tube.
Which technique is correct?
Administering the medications using a 3-mL medication syringe
Applying firm pressure on the syringe’s piston to infuse the medication
Flushing the tubing with 30 mL of saline after the medication has been given
Using the barrel of the syringe, allowing the medication to flow via gravity into the tube
The Correct Answer is C
Choice A rationale:
Administering the medications using a 3-mL medication syringe is not the best practice. While it is possible to use a 3-mL syringe for medication administration, it is not the most efficient or safest method. A larger syringe allows for easier administration and reduces the risk of creating too much pressure which could potentially damage the PEG tube.
Choice B rationale:
Applying firm pressure on the syringe’s piston to infuse the medication is not recommended. This can create too much pressure in the PEG tube and could potentially cause damage. It is generally advised to allow the medication to flow into the tube via gravity. Choice C rationale:
Flushing the tubing with 30 mL of saline after the medication has been given is the correct technique. This helps to ensure that all of the medication has been administered and also helps to keep the tube clear of any potential blockages.
Choice D rationale:
Using the barrel of the syringe, allowing the medication to flow via gravity into the tube is a common practice. However, it is not the only step in the process. It is also important to flush the tube before and after medication administration to ensure all medication is delivered and to maintain the patency of the tube.

Correct Answer is D
Explanation
Choice A rationale:
Liothyronine (Cytomel) is a type of thyroid hormone used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. However, it is not typically used to treat hyperthyroidism.
Choice B rationale:
Liotrix (Thyrolar) is a combination of two thyroid hormones, levothyroxine (T4) and liothyronine (T3), used to treat hypothyroidism, and to prevent and treat goiter. Similar to Liothyronine, it is not typically used to treat hyperthyroidism. Choice C rationale:
Levothyroxine (Synthroid) is used to treat an underactive thyroid (hypothyroidism). It replaces or provides more thyroid hormone, which is normally produced by the thyroid gland. Low thyroid hormone levels can occur naturally or when the thyroid gland is injured by radiation/medications or removed by surgery. Having enough thyroid hormone helps maintain normal mental and physical activity. In children, having enough thyroid hormone helps them grow and learn normally.
Choice D rationale:
Propylthiouracil (Propacil) is an antithyroid agent used in the treatment of hyperthyroidism. It works by decreasing the amount of thyroid hormone produced by the thyroid gland. This helps to prevent the excessive heat, rapid heart rate, and nervousness caused by too much thyroid hormone in the body.
