Summary
Rotating shift work disrupts nurses' rest-activity rhythms (RAR), leading to poorer executive function. Reduced daily stability in RAR is linked to impaired attention and cognitive flexibility in these nurses.
Area of Science:
- Chronobiology
- Occupational Health
- Neuroscience
Background:
- Rest-activity rhythms (RAR) are crucial for health and performance.
- Shift work, common for nurses, is known to disrupt RAR.
- Actigraphy provides objective measures of RAR.
Purpose of the Study:
- To investigate RAR in nurses working rotating shifts.
- To determine the relationship between RAR and executive function in nurses.
Main Methods:
- Compared 11 day-shift (DS) nurses with 11 rotating-shift (RS) nurses.
- Collected demographic data, RAR variables, and sleep data via actigraphy.
- Assessed executive function using cognitive tests.
Main Results:
- RS nurses had significantly shorter total sleep time, lower interdaily stability (IS), and lower relative amplitude (RA) than DS nurses.
- RS nurses exhibited poorer executive performance compared to DS nurses.
- Executive functions like attention (CRT) and cognitive flexibility (TMT-B) were associated with IS in RS nurses.
Conclusions:
- Rotating shift work disrupts nurses' RAR.
- Executive performance is linked to daily IS in nurses working rotating shifts.

1.8K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

Nursing management of dysrhythmias involves the following:AssessmentSubjective Assessment:The initial step involves gathering patient-reported symptoms such as dizziness, palpitations, and chest discomfort. It is crucial to collect a detailed history, including previous heart conditions, current medication use, and lifestyle factors like caffeine and alcohol consumption.Objective Assessment:This involves observing clinical signs such as jugular venous distention, cool and pale skin, and...

01:30Pulse rhythm
960
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
1.9K
Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
