A patient is admitted to the cardiac unit.


Everyone admitted to the cardiac unit will have an EKG done unless otherwise ordered. This is an example of which type of order?

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:

Stage 2 pressure injuries are characterized by partial-thickness loss of skin layers involving the epidermis and/or dermis. They present as a red, blistered area, often with an intact or ruptured serum-filled blister. The wound bed is typically moist and may be painful. There is no exposure of underlying bone, tendon, or muscle.

Key features of Stage 2 pressure injuries that align with the patient's presentation:

Red, blistered area: This is a hallmark sign of Stage 2, indicating tissue damage and inflammation in the epidermis and dermis. Large size: The size of the wound suggests more extensive tissue damage, consistent with Stage 2 rather than Stage 1.

Absence of deeper tissue involvement: The absence of exposed bone, tendon, or muscle rules out Stage 3 or 4 pressure injuries.

Rationales for other choices:

Choice B: Stage 4

Stage 4 pressure injuries involve full-thickness tissue loss with exposed bone, tendon, or muscle. This is not consistent with the patient's presentation, which does not describe exposed deeper tissues.

Choice C: Stage 3

Stage 3 pressure injuries involve full-thickness tissue loss, but without exposed bone, tendon, or muscle. They often present with a deep crater-like appearance and may have undermining or tunneling. The patient's wound does not exhibit these features, making Stage 3 less likely.

Choice D: Stage 1

Stage 1 pressure injuries are characterized by intact skin with non-blanchable redness over a bony prominence. They do not involve blisters or open wounds. The patient's presentation clearly exceeds the features of Stage 1.
