activity

 [ak-tiv´ĭ-te]
1. the quality or process of exerting energy or of accomplishing an effect.
2. a thermodynamic quantity that represents the effective concentration of a solute in a non-ideal solution. Symbol a.
3. the number of disintegrations per unit of a radioactive material. Symbol A.
4. the presence of recordable electrical energy in a nerve or muscle.
a's of daily living (ADL) activities that are necessary for daily care of oneself and independent community living. It includes using the toilet and grooming, dressing, and feeding oneself; independent community living includes driving, shopping, homemaking, care of family, work activities, and so on. See also self care, self care deficit, and self care assistance.(See accompanying table.)
deficient diversional activity a nursing diagnosis approved by the North American Nursing Diagnosis Association, defined as the experiencing by an individual of decreased stimulation from, interest in, or engagement in recreational or leisure activities. Formerly called diversional activity deficit. Possible causes include prolonged hospitalization or immobility at home, frequent and lengthy treatments such as renal dialysis, and a monotonous, nonstimulating environment. The patient usually gives subjective evidence that this condition exists by verbalizing a feeling of boredom or stating a desire for something to do or gives objective evidence by acting depressed or restless.

Nursing interventions that could be appropriate for diversional activity deficit include interviewing the patient to assess the current situation and to assist in developing plans for activities that provide interest and stimulation. These activities could include music, games, reading, handwork, or any other pastimes enjoyed by the patient. Patients may need assistance in identifying available resources and motivation to take advantage of the activities they provide.
enzyme activity the catalytic effect exerted by an enzyme, expressed as units per milligram of enzyme (specific activity) or molecules of substrate transformed per minute per molecule of enzyme (molecular activity).
malignant ventricular ectopic activity ventricular fibrillation or ventricular tachycardia with syncope, heart failure, myocardial ischemia, or hypotension.
optical activity the ability of a chemical compound to rotate the plane of polarization of plane-polarized light.
physical activity bodily movements, such as those accompanying activities of daily living.
pulseless electrical activity (PEA) continued electrical rhythmicity of the heart in the absence of effective mechanical function; it may be due to uncoupling of ventricular muscle contraction from electrical activity or may be secondary to cardiac damage with respiratory failure and cessation of cardiac venous return. Called also electromechanical dissociation.
purposeful activity in occupational therapy, tasks or experiences in which the individual actively participates that require and elicit coordination between the sensory, motor, cognitive, and psychological systems. Each person has a unique set of purposeful activities, influenced by his or her life roles, and, when doing one of them, directs attention to the task itself rather than to the internal processes involved. Activities may yield immediate results or may require sustained effort and repetition, and they may either represent new responses or be part of complex, longstanding patterns of behavior.
sustained rhythmic activity the continuous generation of action potentials within the heart in the absence of artificial or external stimulation.
triggered activity activity in which nondriven action potentials arise from afterpotentials that were caused by the previous action potential.

pea

leguminous plants, members of the family Fabaceae. The plants may be used as green feed but are too succulent to make into hay. Silage is made from the crop residue after harvesting canning peas but is very subject to fungal infestation. Peas used for livestock feed include canning peas (Pisum sativum), field peas (Pisum sativum), chick peas (Cicer arietinum) and cow peas (Vigna sinensis, syn. V. catjang, V. unguiculata). See also lathyrus.

pea hulls
a source of dietary fiber in manufactured pet foods.
pea-struck
poisoning by Darling pea. See swainsona.
pea vine ensilage
is made from the commercial green pea plants after harvesting and removal of pods. It is now more common to harvest pods from the standing crop, which livestock then graze. Ensilage can be poisonous. Lambs show nervous signs soon after birth, an abnormal gait and intermittent recumbency with exercise, and there are degenerative lesions in the cerebral and cerebellar cortices at autopsy.
