The nurse recommends that normal sleep and rest patterns can best be acquired by suggesting to the patient that they:.

Choice A rationale:

Decreased respirations and a rapid heart rate are not indicative of stage 3 of non-rapid eye movement (NREM) sleep. In stage 3, respirations are typically slow and regular, and the heart rate is slower than during wakefulness.

Choice B rationale:

Rapid respirations and a rapid heart rate are indicative of stage 3 of NREM sleep. During this stage, respiration and heart rate are more irregular compared to the earlier stages of sleep. This stage is characterized by increased physiological arousal compared to stages 1 and 2.

Choice C rationale:

Rapid respirations and a slow heart rate do not represent stage 3 of NREM sleep. In this stage, respiration tends to be rapid, and the heart rate, while slower than during wakefulness, is not slow.

Choice D rationale:

Decreased respirations and a slow heart rate are not consistent with stage 3 of NREM sleep. This stage is associated with more active and variable physiological processes, including rapid respirations and a relatively higher heart rate compared to later sleep stages.

Choice A rationale:
The primary care provider (PCP) is responsible for prescribing the PCA but does not typically program the PCA pump. The PCP may set the initial parameters for the PCA, such as the dose and lockout interval, but the actual programming and operation of the PCA pump is typically carried out by the nursing staff.
Choice B rationale:
Pharmaceutical companies manufacture and provide medications, including the medications used in PCA, but they do not program PCA pumps. Programming and administration of the PCA are nursing responsibilities.
Choice D rationale:
Licensed Practical Nurses (LPN) or Licensed Vocational Nurses (LVN) can assist in the administration and monitoring of PCA, but they do not typically program the PCA pump. Registered nurses are usually responsible for the programming and operation of PCA pumps.
