EXAM 2 NSG223 2026 EXAMPREP PRACTICE
SET SOLUTION QUESTIONS WITH FULL
ANSWERS
◉ stertor Answer: Labored breathing that produces a snoring sound
◉ factors that affect respirations Answer: exercise, pain, stress,
smoking, fever, hemoglobin, disease, meds, position, neurological
injury
◉ signs of hypoxia Answer: cyanosis, restlessness, apprehension,
confusion, dizziness, fatigue, decreased level of consciousness,
tachycardia, and BP changes
◉ what is the normal range for adult O2 saturation Answer: 95% or
more
◉ factors that affect oxygen saturation Answer: anxiety, infection,
shock, hypoxia, drugs, acid-base imbalance, disease
◉ what is something to consider about oxygen saturation levels in
older adults with disease Answer: they may have a lower oxygen
saturation level and may require supplemental oxygen
,◉ disease definition Answer: Infection is the invasion of a
susceptible host by pathogens or microorganisms. Infection will
develop if the Chain of Infection stays intact. This infection will
ultimately result in disease.
◉ chain of infection Answer: -infectious agent/pathogen
-reservoir: place where microorganism survives, multiplies, and
waits to be transferred to a susceptible host.
-portal of exit
-mode of transmission
-susceptible host
◉ acute disease Answer: fast onset, severe/abrupt symptoms,
reversible
◉ chronic disease Answer: slow onset, never goes away, persists 6
months or longer
◉ HAI Answer: an infection that develops in a person cared for in
any setting where health care in given. the infection is related to
receiving health care
◉ iatrogenic HAI Answer: from a procedure
, ◉ exogenous HAI Answer: from microorganisms outside the
individual (Salmonella)
◉ endogenous HAI Answer: when patient's normal flora becomes
altered (C.diff)
◉ body's response to stress Answer: Basal metabolic rate increases
as the body uses energy stores. Adrenocorticotropic hormone
increases serum glucose levels and decreases anti-inflammatory
responses. If this lasts a while, it can cause decreased resistance to
infection.
◉ inflammation Answer: protective vascular and cellular reaction to
eliminate pathogens and necrotic tissues.
◉ serous exudate Answer: Watery exudate: indicates early
inflammation
◉ sanguinous exudate Answer: bloody
◉ purulent exudate Answer: Pus: indicates a bacterial infection
(made up of bacteria, neutrophils, monocytes, and WBCs)
