A nurse is reinforcing teaching with a client who is 12 hr postpartum and has an episiotomy.
Which of the following instructions should the nurse include?

A. Depersonalization is a feeling of detachment from oneself or feeling like one's thoughts, feelings, and actions are not their own. It does not involve perceptual disturbances such as hearing voices.
B. Hallucination is a sensory perception that occurs in the absence of external stimuli. Auditory hallucinations involve hearing voices or sounds that others do not hear, as described by the client in this scenario.
C. Illusion is a misinterpretation of a sensory stimulus that is actually present in the environment. It involves a distortion or misperception of sensory information, not the perception of something that is not there, as in the case of hallucinations.
D. Derealization is a feeling of unreality or detachment from one's surroundings. It involves a distortion in the perception of the external world rather than sensory experiences such as hearing voices.

- Rationale for A: The name and medical record number are unique identifiers that are used to accurately match a newborn with their medical records and ensure that the correct medication is administered. This method of identification minimizes the risk of medical errors, which is crucial in a hospital setting where multiple newborns may be present.

- Rationale for B: While the birth date and mother's name are important, they may not be as effective for identification because multiple newborns could share a birth date, and there could be more than one mother with the same name in the maternity ward.

- Rationale for C: Age and diagnosis are not specific enough for the identification of a newborn when administering medication. Age is not a distinguishing factor in a neonatal unit, and the diagnosis could apply to multiple infants.

- Rationale for D: Footprints and identification number can be used as secondary identifiers. However, footprints may change rapidly as the newborn grows, and the identification number should be cross-referenced with the name and medical record number for accurate identification.
