Which of the following is included in a prescribing error?

The correct answer, which identifies a prescribing error, is related to ordering an incorrect dosage form. Prescribing errors occur when a healthcare provider makes a mistake in the process of prescribing a medication that can negatively impact patient safety and treatment efficacy. Ordering the wrong dosage form can lead to issues such as inadequate drug absorption, altered pharmacokinetics, or other adverse effects that compromise patient care.

In contrast, clear patient instructions and transcribing a medication correctly are actions that promote safe medication use and effective communication, thereby reducing the likelihood of medication errors. Prescribing a medication with known allergies is a serious lapse but specifying an incorrect dosage form directly impacts the medication's effectiveness and patient safety, thereby qualifying it as a prescribing error.
