Rest

The NCLEX rarely asks “what is rest”; it tests which nursing action best promotes it, so the answer usually hinges on protecting full sleep cycles (~90 minutes each — deep NREM concentrates early in the night, REM later, so a client needs roughly 90 uninterrupted minutes to finish even one cycle). The classic “tell” is a hospitalized client with frequent disruptions: group assessments, meds, and vitals into single visits rather than waking the client for non-urgent tasks. Watch for options that look kind but harm sleep — caffeine within 4 hours of bedtime, long daytime naps, or a TV/screen left on. Favor nonpharmacologic measures first (dim lighting, reduced noise, a back rub, warm milk); reserve sedative-hypnotics, which raise fall and delirium risk in older adults (per the AGS Beers Criteria).

Do not confuse rest with comfort: comfort centers on relieving pain and distress, while rest is the restorative inactivity healing requires — a pain-free client may still be sleep-deprived from interruptions.
