    Factors Affecting Body Temperature01:28

    Factors Affecting Body Temperature

    As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
    Factors may  include:
    Increased Body Temperature01:25

    Increased Body Temperature

    A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
    Methods of reducing fever01:22

    Methods of reducing fever

    The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.
    Pharmacological Methods of Reducing Fever:
    Temperature Measurement Sites01:14

    Temperature Measurement Sites

    A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
    Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...
    Assessing Body Temperature - Rectal01:27

    Assessing Body Temperature - Rectal

    Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
    Follow these steps for rectal temperature assessment:
    Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
    Step 2: Position the patient in a side-lying position to better visualize the rectal...
    Assessing Body Temperature - Temporal Artery01:19

    Assessing Body Temperature - Temporal Artery

    Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
    Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
    Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
    Step 3: Assess the patient's forehead...
