The adult child of an older adult calls the nurse practitioner to report that the parent is becoming very confused after dark. What is this type of confusion named?

A. Administer oxygen at 2 L/min: Administering oxygen is important but should be done after positioning the client to improve natural ventilation.

B. Raise the head of the bed: Raising the head of the bed is the first action to take as it facilitates better lung expansion and improves ventilation. This can help increase the oxygen saturation more immediately and effectively.

C. Encourage coughing and deep breathing: Encouraging coughing and deep breathing is also beneficial to help clear secretions and improve lung function, but positioning the client for optimal breathing should be prioritized first.

D. Administer prescribed analgesic medication. Administering analgesics may be necessary for pain management, but it does not directly address the immediate need to improve oxygen saturation.

A. Covert: Covert data refers to information that is hidden, subjective, or not immediately observable, such as symptoms reported by the client. Voided volume is measurable and observable, so it is not covert.

B. Subjective: Subjective data is information reported by the client, such as feelings, perceptions, or symptoms. Since the urine output is a measurable and observable fact, it is not subjective.

C. Objective: Objective data is factual, measurable, and observable. The voided volume of 475 ml is a precise, quantifiable measurement, making it objective data.

D. Symptomatic: Symptomatic data pertains to symptoms experienced by the client, which are typically subjective. The documented urine output is a specific, quantifiable measurement and not a symptom.
