What is considered when assessing pain?
Patient history, location, onset, duration, aggravating factors, quality (descriptive), intensity, functional status (ADLs), desired pain/activity level (patient's expectations), analgesic history (what works and what doesn't).
Gate control theory of pain
It describes the transmission of painful stimuli and recognizes a relation between pain and emotions. The exciting and inhibiting signals at the gate in the spinal cord determine the impulses that eventually reach the brain. When too much info is sent through, certain cells in the spinal column interrupt the signal as if closing a gate.
Intractable pain
When pain is resistant to therapy and persists despite a variety of interventions.
When (chronic pain) symptoms reappear.
Chronic pain
Pain that may be limited, intermittent, or persistent but lasts for 6 months or longer and interferes with normal functioning.
Acute pain
Rapid onset, varies in intensity from mild to severe, and may last up to any period less than 6 months. It's protective in nature. After the underlying cause is resolved, acute pain disappears.
Local anemia resulting from poor circulation.
Idiopathic pain
A diagnosis of exclusion in which pain is suffered by a patient for longer than 6 months, for which there is no physical cause and no specific mental disorder.
Neuropathic pain
It's the result of an injury or malfunction in the peripheral or CNS. The pain is often triggeres by an injury.

Pain may persist for months or years. Pain no longer triggers the receptors, instead the alarm system itself is malfunctioning. Frequently the pain is chronic. It doesn't usually respond well to opioids but to antiseizure and anti-anxiety meds.
Nociceptive pain
Nociceptors are the nerves which sense and respond to parts of the body which suffer from damage. This is usually time-limited (exception is arthritis). Usually responds well to treatment with opioids.
Mechanisms of pain
1. nociceptive
2. neuropathic
3. idiopathic
4. phantom pain
5. ischemic pain
3 Hierarchical levels of pain
1. sensory - doscriminative component
2. motivation-affective component
3. cognitive-evaluation component
What is the pain process?
1. Transduction - activation of pain receptors
2. Transmission - conduction along pathways. Nerve endings receive painful stimuli.
3. Modulation - initiation of the protective reflex response.
4. Perception of pain - awareness of the characteristics of pain

What is the goal of the health belief model?
To reduce cultural and environmental barriers that interfere with access to health care.
Family genogram

In maternity nursing, what does the nurse's resp include?
Assessment, diagnosis, planning, implementation, and evaluation.

It focuses on women and their infants and families during the childbearing cycle.
Evidence-based practice
Providing care based on evidence gained through research and clinical trials.

Hemorrhage, shock, Thrombophlebitis, pulmonary embolus, resp. complications (pneumonia, atelectasis)
What type of an assessment/intervention is needed postoperatively?
Elimination needs, meeting fluid and nutrition needs, comfort and rest needs
What types of issues will arise for patients in the preoperative period?
Developmental considerations, past medical history, medications, previous surgery, nutrition, use of drugs or smoking, support systems, teaching about the procedure.
Roles and responsibilities of the perioperative nurse.
It’s the nurse’s resp. to identify factors that affect the risk of a surgical procedure. Assessing the physical and psychosocial needs of the patient and family and establishing a plan of care and to facilitate the patient’s recovery.
The neurotransmitters responsible for pain.
Prostaglandins, substance P, and serotonin
The difference between opioids and nonopioids
Opioids produce analgesia by attaching to opioid receptors in the brain. They are for moderate to severe pain. Nonopioid analgesics are usually the drugs of choice for mild to moderate pain.
What affects drug absorption?
If a drug binds with another substance in the GI tract, such as milk and antacids. This is the chelation effect. Food and laxatives may also affect it.
What drug interactions affect drug distribution?
2 Types of interactions: The first is competitive protein binding. The second way is when a drug alters the extracellular pH.
What drug interactions affect metabolism of the drug?
Some drugs either enhance induce or inhibit the P-450 system.
What drug interactions affect excretion of the drug?
Drugs can alter renal filtration, renal absorption, or renal secretion. In doing so they may alter the excretion of other drugs. Drugs that decrease cardiac output decrease the amount of circulating blood that is sent to the kidneys.
