What is the first intervention of the nurse for changing the dressing to a painful burn?

Choice A rationale:

Incorrect dosage form: Metformin is typically administered orally as a tablet or liquid suspension, not as a powder for reconstitution (PO).

Missing route of administration: The medication order does not specify the route of administration, such as oral (PO), intravenous (IV), or intramuscular (IM).

Potential for medication errors: The lack of clarity in the medication order could lead to errors in administration, such as giving the wrong dose or administering the medication by the wrong route.

Choice B rationale:

Incorrect dosage unit: Methotrexate is typically administered in milligrams (mg), not grams (g).

Potential for overdose: The order for 15.0 g of methotrexate is a very high dose that could lead to serious adverse effects, including toxicity and death.

Choice C rationale:

Correctly written: The medication order specifies the drug name (meropenem), the dose (1.0 g), the dosage form (IV), and the route of administration (IV).

Appropriate dosage range: The dose of 1.0 g of meropenem is within the typical dosage range for this antibiotic.

Clear and concise: The medication order is clear, concise, and easy to understand, which helps to reduce the risk of medication errors.

Choice D rationale:

Incorrect: While choices A and B are both incorrect, choice C is a correctly written medication order.

Choice A rationale:

Side effect: A side effect is an effect of a drug that is secondary to the main intended effect. It is usually predictable and may be either beneficial or harmful. However, constipation is not a common or expected side effect of iron supplements. It is more likely to be an adverse reaction.

Choice B rationale:

Therapeutic effect: The therapeutic effect is the intended effect of a drug, the one that is desired to treat the condition. In this case, the therapeutic effect of the iron supplement would be to increase the patient's iron levels. Constipation is not the desired effect of the iron supplement, so it is not a therapeutic effect.

Choice C rationale:

Adverse reaction: An adverse reaction is an unwanted or harmful reaction to a drug that is not necessarily predictable. It can range from mild to severe. Constipation is a common adverse reaction to iron supplements. It is thought to be caused by the iron binding to undigested food in the intestines, making it harder to pass stool.

Choice D rationale:

Toxicity: Toxicity refers to a poisonous or harmful effect of a drug. It is usually caused by taking too much of a drug or by a drug interacting with another drug or substance. Constipation is not a sign of iron toxicity. Iron toxicity can cause symptoms such as nausea, vomiting, abdominal pain, and diarrhea.
