When given an intravenous medication, the patient asks the nurse, “I usually take pills.
Why does this medication have to be given in the arm?” What is the nurse’s best response?
“The intravenous medication will have delayed absorption into the body’s tissues.”
“The action of the medication will begin sooner when given intravenously.”
“The medication will cause fewer adverse effects when given intravenously.”
“There is a lower chance of allergic reactions when drugs are given intravenously.”
The Correct Answer is B
Choice A rationale:
The statement “The intravenous medication will have delayed absorption into the body’s tissues” is incorrect. Intravenous (IV) therapy is administering fluids directly into a vein. It benefits treatment by enabling water, medication, blood, or nutrients to access the body faster through the circulatory system. This bypasses the gastric system so the body can take on more fluids quickly. Therefore, the absorption of intravenous medication into the body’s tissues is not delayed but rather immediate.
Choice B rationale:
The statement “The action of the medication will begin sooner when given intravenously” is correct. Administering a medication intravenously eliminates the process of drug absorption and breakdown by directly depositing it into the blood. This results in the immediate elevation of serum levels and high concentration in vital organs, such as the heart, brain, and kidneys. Therefore, the action of the medication begins sooner when given intravenously.
Choice C rationale:
The statement “The medication will cause fewer adverse effects when given intravenously” is not necessarily true. While some medications might cause fewer adverse effects when given intravenously, this is not a general rule for all medications. The adverse effects of a medication depend on various factors including the type of medication, the dose, the patient’s health condition, and more.
Choice D rationale:
The statement “There is a lower chance of allergic reactions when drugs are given intravenously” is not necessarily true. The chance of allergic reactions depends on various factors including the type of drug, the patient’s immune response, previous exposure to the drug, and more. It’s not related to the route of administration.

Explanation
Answer and explanation
The question is about calculating the volume of methylnaltrexone to administer to a client. The client needs a dose of 12 mg, and the available methylnaltrexone is 8 mg/0.4 mL.
Let’s calculate the volume step by step:
Step 1: Identify the given values:
- Desired dose (D) = 12 mg
- Available dose (A) = 8 mg
- Volume for available dose (V) = 0.4 mL
Step 2: Use the given values in the formula for calculating the volume to administer:
Volume to administer=Available doseDesired dose×Volume for available dose Step 3: Substitute the given values into the formula:
Volume to administer=(12*0.4)/8
Step 4: Perform the multiplication and division:
Volume to administer=4.8mL/8
Step 5: Simplify the division to find the volume to administer:
Volume to administer=0.6mL
So, the nurse should administer 0.6 mL of methylnaltrexone to the client.
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.
