RNSG 1216 Exam 1 Qestions & Answers Graded A+

Afebrile - Answer without fever Antipyretics - Answer medications that reduce fever Auscultatory gap - Answer temporary disappearance of sounds usually heard over the brachial artery, occurring when the cuff pressure is high and is gradually reduced, with the sounds again heard at a lower level of pressure (usually occurring in patients who have hypertension) basal metabolic rate (BMR) - Answer The rate at which heat is given off by an organism at complete rest. Blood pressure - Answer The force exerted on the walls of an artery by the pulsing blood under pressure form the heart Bradycardia - Answer a slow heart rate below 60 beats/min Capnography - Answer a measurement of exhaled carbon dioxide throughout exhalation. Cardiac output - Answer The volume of blood ejected from the left side of the heart in one minute. HR x SV. Conduction - Answer The transfer of heat from one object to another with direct contact. Convection - Answer The transfer of heat away by air movement. Core temperature - Answer temperature of the deep tissues Diaphoresis - Answer visible perspiration primarily occurring on the forehead and upper thorax. Diastolic pressure - Answer Occurs when the ventricles are relaxed; the lowest pressure against the walls of an artery Dyspnea - Answer Difficult or uncomfortable breathing or shortness of breath. Diffusion - Answer Movement of oxygen and carbon dioxide between alveoli and red blood cells. Dysrhythmia - Answer An interval interrupted by an early or late beat or a missed beat Eupnea - Answer normal breathing Evaporation - Answer The transfer of hear energy when a liquid is changed to a gas Febrile - Answer fever Fever - Answer elevated body temperature Fever of unknown origin (FUO) - Answer fever with an undetermined cause Frostbite - Answer Actual freezing of tissue fluid resulting in damage to the skin and underlying tissue Heat exhaustion - Answer Occurs when profuse diaphoresis results in excess water and electrolyte loss, caused y environmental heat exposure. Heatstroke - Answer Prolonged exposure to the sun or a high environmental temperature overwhelms the heat loss mechanisms of the body. Body temp of 40C (104F) Hematocrit - Answer The percentage of red blood cells in the blood, determines blood viscosity. Hypertension - Answer abnormally high blood pressure Hyperthermia - Answer An elevated body temperature related to the inability of the body to promote heat loss or reduce heat production. Hypotension - Answer Is present when the systolic BP falls to 90 mmHg or below. Hypothermia - Answer heat loss during prolonged exposure to cold overwhelms the ability of the body to produce heat Hypoxemia - Answer decreased level of oxygen in the blood Malignant hyperthermia - Answer A hereditary condition of uncontrolled heat production that occurs when susceptible people receive certain anesthetic drugs. Nonshivering thermogenesis - Answer Occurs primarily in neonates. Because neonates cannot shiver, a limited amount of vascular brown adipose tissue present at birth can be metabolized for heat production. Orthostatic hypotension - Answer Decrease in blood pressure related to positional or postural changes from lying to sitting or standing positions Oxygen saturation - Answer a clinical measurement of the percentage of hemoglobin that is bound with oxygen in the blood
