List in order the steps of the nursing process
1. Assessment2. Nursing diagnosis3. Planning goals and outcomes4. Implementing5. Evaluating
46
The part of the nursing process where you gather information and collect data about your patient
Assessment
47
Clinical judgement part of the nursing process made about the patient's health within the nurse's scope of practice, so what the nurse is able to control, two basic ways of of analyzing the patient would be by deficient knowledge and noncompliance
Nursing Diagnosis
48
The phase of the nursing process in which nurses prioritize their diagnosis, educate the patient about it, and formulate goals/outcomes
Planning
49
The part of the nursing process when the patient reassesses the patient and comes up with the nursing interventions that would allow the patient to move forward such as re administering a drug
Implementing
50

Autonomic Nervous system
72
Activated under the conditions of the fight or flight response
Sympathetic division of the Autonomic Nervous system
73
Activated under the nonstressful conditions and produces a rest and digest response
Parasympathetic division of the Autonomic Nervous System
74
Stimulate the sympathetic division (fight-or-flight) and are made up of Alpha and Beta receptors. can also be selective or non selective
Adrenergic receptors
75
Stimulate the parasympathetic division (rest-and-digest) and are nerves that release acetylcholine which stimulates smooth muscle, gland secretion, and a decreased heart rate
Cholinergic receptors
