Exam Questions and CORRECT Answers
infection - CORRECT ANSWER - the invasion and multiplication of microorganisms in
body tissues, which may be unapparent, or the result of local cellular injury caused by
competitive metabolism, toxins, intracellular replication, or antigen-antibody response.
•Bacterial
•Viral
•Fungal
•Parasitic or protozoal - CORRECT ANSWER - What are the 4 types of infection?
-Nasal cavity= Nares (or nostrils)
-Pharynx (throat)
-Larynx is located between the pharynx and trachea and houses the vocal cords
-Ciliated mucous membranes
-Tonsils - CORRECT ANSWER - What does the upper respiratory system consist of?
-Trachea
-Lungs
-Primary bronchi
-Alveoli where gas exchange occurs - CORRECT ANSWER - What does the lower
respiratory system consist of?
RSV (upper respiratory tract infection) - CORRECT ANSWER - •Accounts for over 50%
of cases of bronchiolitis (a lower respiratory tract infection)
•Peak symptoms day 2-3
•Symptoms may last 10-14 days (edema, mucous, impaired gas exchange, hypoxemia)
•Immunity does not occur
, •Highest incidence November-March
S/S: Serous nasal drainage, sneezing, low-grade fever, anorexia, acute respiratory distress,
tachypnea, tachycardia, wheezing, crackles, or rhonchi, intercostal and subcostal retractions,
nasal flaring, cyanosis
Diagnosed: Respiratory viral panel (nasal swab) and Chest x-ray
Treatment: treatment is symptom based, keep hydrated through IV, assess vitals, oxygen if pulse
ox is <92%, nasal suction (wall is most effective), saline spray to break up mucus, treat fevers
with medications - CORRECT ANSWER - What are S/S of RSV? How is it diagnosed?
How is RSV treated?
•Frequent and thorough hand hygiene
•Cleaning contaminated surfaces
•Vaccination (mother can get RSV vaccine if she is between 32 and 36 weeks; infants can get
antibody if less than 8 weeks)
-CONTACT preventions - CORRECT ANSWER - What are precautions for RSV? How is
it prevented?
gas exchange - CORRECT ANSWER - the process by which oxygen is transported to cells
and carbon dioxide is transported from cells
when the diffusion of gases (oxygen and carbon dioxide) becomes impaired because of:
•Ineffective ventilation
•Reduced capacity for gas transportation (reduced hemoglobin and/or red blood cells)
•Inadequate perfusion - CORRECT ANSWER - When does impairments of gas exchange
occur? What are things that can cause this to happen?
asthma - CORRECT ANSWER - A chronic obstructive airway disease characterized by:
•Increased airway responsiveness to a variety of stimuli
•Bronchospasm resulting from constriction of bronchial smooth muscle
