A nurse is caring for an 11-month-old toddler who has been hospitalized for 10 days. After the toddler's mother leaves the room, the nurse observes the toddler sitting quietly in the corner of the crib, sucking her thumb. When the nurse approaches the crib, the toddler turns away from the nurse. The nurse should understand that these behaviors indicate which of the following developmental reactions?

A. Using touch to calm the client during periods of anxiety: Clients with paranoid schizophrenia may have heightened sensitivity to touch and may interpret it as threatening or intrusive. Therefore, using touch to calm the client may exacerbate their anxiety rather than alleviate it.

B. Rotating staff assignments for this client: Consistency in staff assignments can help establish trust and rapport with clients with paranoid schizophrenia. Rotating staff may disrupt this continuity and potentially increase the client's paranoia and suspicion.

C. Checking the client's mouth after the client takes medication: Clients with paranoid schizophrenia may exhibit medication non-compliance due to distrust or suspicion of medications. Checking the client's mouth after medication administration ensures that the client has ingested the medication and helps prevent hoarding or hiding of medication.

D. Assigning assistive personnel to feed the client at mealtimes: Clients with paranoid schizophrenia may have difficulty trusting others, particularly with personal activities such as feeding. Assigning assistive personnel to feed the client may increase the client's paranoia and resistance to care. It's essential to promote the client's autonomy and independence while providing support as needed.

A. Before auscultating the chest and abdomen: Examining the tympanic membrane before auscultating the chest and abdomen is not ideal. It's important to follow a systematic approach in physical examination, typically starting with less invasive assessments before progressing to more invasive or uncomfortable ones. Therefore, examining the tympanic membrane before auscultating the chest and abdomen may disrupt this systematic approach.

B. Before examining the head and neck: Similarly, examining the tympanic membrane before examining the head and neck is not appropriate. The head and neck examination typically includes less invasive assessments such as observing the child's appearance, palpating the fontanelles, and inspecting the scalp, face, and neck. The tympanic membrane examination, which involves using an otoscope, is more invasive and should be performed later in the examination.

C. At the end: This is the correct choice. Examining the tympanic membrane at the end of the physical examination allows the nurse to establish rapport with the child and gain their cooperation before performing a potentially uncomfortable or intrusive examination of the ears. Starting with less invasive and more familiar assessments, such as observing the child's general appearance and behavior, auscultating the chest and abdomen, and examining the head and neck, can help build trust and reduce anxiety before proceeding to more specific assessments, such as otoscopy.

D. At the beginning: Examining the tympanic membrane at the beginning of the physical examination may cause the child distress and anxiety, potentially making the rest of the examination more challenging. It's preferable to perform less invasive assessments first to help the child become more comfortable and cooperative before proceeding to more invasive examinations like otoscopy. Therefore, examining the tympanic membrane at the beginning is not recommended.
