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.”

Answer and Explanation

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.

Correct Answer is C

Explanation

Choice A rationale:

Proton pump inhibitors (PPIs) are used extensively for the treatment of gastric acid-related disorders, often over the long term, which raises the potential for clinically significant drug interactions in patients receiving concomitant medications.

However, there is no specific mention of a significant interaction between PPIs and aminoglycosides.

Choice B rationale:

Aminoglycoside antibiotics and calcium channel blockers can interact at the neuromuscular junctions. This interaction is of clinical significance because when these agents are given concurrently during the perioperative period they may lead to respiratory depression or prolonged apnea. However, this is not directly related to the therapeutic effect of aminoglycosides, but rather a side effect of their combined use.

Choice C rationale:

The loop-diuretics (ethacrynic acid, furosemide, bumetamide) and aminoglycoside antibiotics (kanamycin, gentamicin, tobramycin, amikacin, etc.) are important drugs frequently used to treat seriously ill patients. Not uncommonly both types of drugs are given to the same patient exposing that patient to the risk of a hearing loss (ototoxicity)5. In addition, the risk of ototoxicity could be enhanced by the concomitant use of loop diuretics and aminoglycoside antibiotics.

Choice D rationale:

Phenytoin is a medication used to treat seizures. It has a complex pharmacokinetic profile and can interact with many other drugs. However, there is no specific mention of a significant interaction between phenytoin and aminoglycosides.

A. Blood glucose levels B. Thyroid function studies C. Liver function tests D. Gallbladder studies .

Correct Answer is C

Explanation

Choice A rationale:

Blood glucose levels are not typically affected by rifampin and pyrazinamide. These medications are primarily used to treat tuberculosis and do not have a direct impact on blood sugar levels.

Choice B rationale:

Thyroid function studies are not usually required when a patient is on rifampin and pyrazinamide. These medications do not typically affect the thyroid gland or its function.

Choice C rationale:

Liver function tests are crucial when a patient is on rifampin and pyrazinamide. Both of these medications can cause liver problems, including hepatitis. Therefore, regular monitoring of liver function is necessary to detect any potential damage early and adjust the treatment plan accordingly.

Choice D rationale:

Gallbladder studies are not typically required for patients on rifampin and pyrazinamide. These medications do not have a known direct impact on the gallbladder.
