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.

Correct Answer is C
Explanation
Choice A rationale:
The client stating, “I haven’t had anything to eat or drink since last night” is not a cause for concern. This is because patients are often advised to fast before undergoing certain medical procedures or tests, including an intravenous pyelogram (IVP).
Fasting helps to ensure that the test results are accurate and not influenced by recent food or drink consumption.
Choice B rationale:
The client expressing that “The last time I voided it was painful” could be related to their recurrent kidney stones. Kidney stones can cause discomfort or pain during urination. However, this statement does not necessarily require additional data collection in the context of an IVP. The pain could be a symptom of the kidney stones rather than a contraindication for the IVP1.
Choice C rationale:
The statement “I took my metformin before breakfast” is of concern. Metformin is a medication used to treat type 2 diabetes. It is important for the nurse to collect additional data about this statement because metformin can potentially interact with the iodine-based contrast dye used in an IVP. This interaction can increase the risk of lactic acidosis, a serious and potentially lifethreatening condition. Therefore, patients are often advised to stop taking metformin before and for a couple of days after having an IVP12. Choice D rationale:
The client mentioning, “I took a laxative yesterday” is not necessarily alarming. Laxatives are often used before an IVP to clear the bowels, which helps to ensure clear images during the procedure. Therefore, this statement does not require additional data collection in the context of an IVP1.
Correct Answer is ["2.5 "]
Explanation
Step 1: Identify the given values. The nurse needs to administer 2.5 mg of hydromorphone. The available amount is 5 mg/5 mL.
Step 2: Set up the calculation. We need to find out how many mL correspond to 2.5 mg. We can set up a proportion using the given values:
5 mL5 mg=x mL2.5 mg
Step 3: Solve for x. Cross-multiply and solve for x:
5 mg×x mL=2.5 mg×5 mL
Step 4: Simplify the equation:
x=5 mg.5 mg×5 mL
Step 5: Calculate the value of x:
x=2.5 mL
So, the nurse should administer 2.5 mL of the hydromorphone elixir.
