If a patient opts for an herbal supplement over a prescribed medication, what would be the nurse’s best response?

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.

The correct answer is Choice A.

Choice A rationale:

Tetanus is an acute infectious disease caused by spores of the bacterium Clostridium tetani.The spores are found everywhere in the environment, particularly in soil, ash, intestinal tracts/feces of animals and humans, and on the surfaces of skin and rusty tools like nails, needles, barbed wire, etc.Anyone can get tetanus, but the disease is particularly common and serious in newborn babies and pregnant women who have not been sufficiently immunized with tetanus-toxoid-containing vaccines.

To ensure that there is adequate antitoxin to neutralize tetanus toxin in the case of a tetanus-prone injury, a booster dose is advised if it has been longer than 10 years since the last tetanus vaccine dose.This is because a single dose of tetanus toxoid produces a rapid anamnestic response. Therefore, if a patient with a puncture wound has not received a tetanus toxoid vaccination in the last 10 years, they would require an additional injection before being discharged from the emergency department.

Choice B rationale:

While it might seem prudent to administer a tetanus toxoid vaccination every year, this is not necessary according to current medical guidelines.Over-vaccination could potentially lead to an increased risk of adverse reactions without providing additional benefits. Therefore, a tetanus toxoid vaccination is not required every year.

Choice C rationale:

A 5-year interval for tetanus toxoid vaccination is not the standard recommendation for general population.However, in some specific cases, such as when indicated for wound management, a tetanus toxoid–containing vaccine might be administered if ≥5 years have elapsed since the previous receipt of any tetanus toxoid–containing vaccine.

Choice D rationale:

A 2-year interval for tetanus toxoid vaccination is not the standard recommendation.The tetanus toxoid vaccination provides protection for a much longer period, and therefore, it is not necessary to administer the vaccine every 2 years.
