Question | Answer |
---|---|
vasodilation | increase in size of vessel lumen |
phagocytosis | white blood cells surround, engulf,& digest microorganisms |
metabolism | chemical & physical processes required to build & maintain body tissues |

type of heat penetrated best | moist heat- better conductor |
fever reduction, pain relief, hemostasis, prevention of swelling | common uses for cold application |
risk associated with sitz bath | orthostatic hypotension - due to increased blood flow to the perineum |
time maximum vessel dilation achieved when using heat application | 20-30 minutes |
should heat be used on sprained ankle? Why? | heat will increase swelling. do not use heat until swelling has stopped |
how does cold help sprained ankle | constricts the blood vessels and lessens the swelling |

2 chemicals released during injury and and damage to tissue | substance P or prostaglandins |
Adjuvent drugs anti-depressant/anti-convulsants | meds that either produce pain relief from a mechanism different than traditional analgesics or by potentiating or increasing the effects of opiates, opiods, & nonopiod drugs |
Analgesics | pain meds |
Effluerage | repetitive gentle, gliding stroking of your finger over the the surface of the skin for the purpose of pain relief |
Endorphins | The natural body chemicals produced by the brain in response to pleasant thoughts or feelings, exercise, laughter, sex, and massage;act similar to morphine; and produce feelings of euphoria, well-being, and pleasure. |

98 y/o severe diabetes with left leg amputation states that his left foot hurts. What would he be referring to? | Phantom limb pain |
Gate Control Theory | Transmission of pain impulses, caused by stimulation of the broad nerve fibers by heat, cold, massage, and exercise is thought to open the gate, allowing impulses to be transmitted. It is thought that the thalmus can open the gate when stress/anxiety incr |
An individual's thought and emotions are also believed to affect the opening and closing of the gate by stimulating production of? | Endorphins |
Nociceptive pain | Cutaneous pain/paper cut. Soft tissue pain/ injury/thigh muscle/subcutaneous tissue. Deep somatic pain/arthritis/fx.Deep visceral pain/Hysterectomy/post-op pain. |
Information to be included on a pain assessment. | Characteristics of pain/level of pain/what the patient wants done for the pain. |
How can you help a patient in severe pain and waiting for the medication to take effect? | explain to the patient what you are going to do. Verbally direct the patient to focus her conscious mind on the sequential tightening/relaxing of muscles/head to feet. |
Benefits of PCA? | Patient feels in control. Doesn't have to wait for nurse to administer meds. |
