A medication error refers to any preventable event that may cause or lead to inappropriate medication use or patient harm. In this case, the nurse administering a double dose of medication due to a failure to cut the pill in half is a medication error. It involves the administration of an incorrect dose, which can potentially result in harm or adverse effects for the patient.

The other situations mentioned do not necessarily indicate medication errors. A patient developing hives after starting an IV antibiotic could have an allergic reaction, and appropriate actions should be taken to address the reaction. A patient complaining of severe pain still present after receiving pain medication may require further assessment and intervention to manage their pain effectively. A patient refusing her morning medication is not a medication error but rather a patient's right to refuse treatment, and appropriate documentation and communication should be done in such situations.

Codeine is an opioid medication that can cause drowsiness and dizziness. Changing positions quickly, especially from lying down to standing up, can increase the risk of falls or accidents.
Instructing the client to change positions slowly helps prevent orthostatic hypotension (a drop in blood pressure upon standing) and reduces the risk of falls.
The other options listed are not appropriate instructions for a client taking codeine:
A. "You should expect to experience diarrhea while taking this medication." While constipation is a common side effect of opioids, diarrhea is not typically associated with codeine use. Therefore, there is no need to expect or warn about diarrhea as an anticipated effect of taking codeine.
C. "You should limit alcohol intake to 12 ounces daily." Mixing alcohol with codeine can have harmful effects, such as increased sedation and respiratory depression. However, it is generally recommended to avoid alcohol completely while taking codeine, rather than setting a specific limit of 12 ounces daily.
D. "You should take the medication on an empty stomach to prevent nausea." Taking codeine with or without food can vary depending on individual factors and the specific instructions provided by the healthcare provider. However, taking codeine on an empty stomach does not necessarily prevent nausea. In fact, taking it with food may help reduce stomach upset for some individuals. It is best to follow the specific instructions provided by the healthcare provider regarding the timing of codeine administration with or without food.
