General Adaptation Syndrome (GAS) - Correct answer-A three-stage physiological
response developed by Hans Selye to explain how the body reacts to stress.
Alarm stage - Correct answer-The 'fight-or-flight' response — the sympathetic
nervous system activates; adrenaline, norepinephrine, and cortisol levels rise.
Resistance stage - Correct answer-The body attempts to adapt to the stressor;
hormone levels stabilize, and energy is directed toward maintaining homeostasis.
Exhaustion stage - Correct answer-Prolonged exposure to stress depletes the body's
resources, leading to fatigue, weakened immunity, and increased risk of illness.
Nursing relevance of GAS - Correct answer-Nurses must recognize prolonged
stress responses, which can affect wound healing, immune function, and patient
recovery.

, CAUTIs (Catheter-Associated Urinary Tract Infections) - Correct answer-A urinary
tract infection that develops in a patient who has had an indwelling urinary catheter
for more than 48 hours.
Causes of CAUTIs - Correct answer-Poor aseptic insertion, prolonged catheter use,
or contamination from the drainage system.
Prevention of CAUTIs - Correct answer-Use aseptic technique for insertion, keep
the drainage bag below bladder level, ensure a closed drainage system, perform
daily catheter care and remove the catheter as soon as it's no longer necessary.
Nursing note on CAUTIs - Correct answer-CAUTIs are a preventable hospital-
acquired infection (HAI) and a major focus of infection control policies.
Fluid Imbalance - Main Assessment Indicator - Correct answer-Daily weight is the
most accurate indicator of fluid balance.
Weight change indicator - Correct answer-A 1 kg (2.2 lb) weight change = 1 liter of
fluid gained or lost.
Potassium (K⁺) - Correct answer-A major intracellular cation vital for muscle
contraction, nerve impulse transmission, and maintaining normal cardiac rhythm.
Normal range of Potassium - Correct answer-3.5-5.0 mEq/L
