NU 300 EXAM 3 QUESTIONS AND
ANSWERS GRADED A+ 2026
Identify the reason for the use of accessory muscles for breathing - ANS the pt is
experiencing some form of respiratory distress
what will the nurse seen upon physical assessment if a patient is using accessory muscles to
breathe? - ANS use of neck, chest, abdominal muscles when breathing
many changes occur in the respiratory system as a person ages. what impact do these changes
have on the function of the respiratory system of an older adult? - ANS alveolar surface area
decreases, ability to cough decreases, elasticity decreases, muscle atrophy
what are key interventions to promote health in the older population related to the respiratory
system? - ANS encourage pulmonary hygiene, encourage upright position, encourage
frequent oral hygiene
what drugs are contraindicated due to CV and mental health risks? - ANS bupropion and
chantix (mania, hallucination), nicotine patches (stroke, MI)
identify strategies to help a person stop smoking - ANS write pros and cons, set a stop date
and stick to in, seek support, remove stimulus and replace, find hand busying activities, keep
low cal snacks, positive comments, 8 glasses of water per day

, high flow nasal cannula - ANS 30-60 L/min, heat and humidity provide higher concentration,
less tissue trauma and improve end expiratory volume
venturi mask - ANS most accurate, humidification not needed, best for patients with chronic
lung diseases
low flow nasal cannula - ANS 1-6 L/min, apply water soluble jelly to nares PRN
simple face mask - ANS 5-8 L/min, skin care to area covered by mask
partial rebreather mask - ANS 6-11 L/min, keep reservoir bag inflated
what complications should the nurse monitor for following placement of a trach? - ANS tube
obstruction, dislodgement/decannulation, pneumothorax, subq emphysema, bleeding, infection
tracheomalacia s/s - ANS increased amt of air required in cuff to maintain seal, larger tube is
required to prevent air leak, food particles seen in tracheal secretions, pt does not receive set
tidal volume on ventilator
tracheomalacia management - ANS nothing unless bleeding occurs
tracheomalacia prevention - ANS use an uncuffed tube as soon as possible, monitor cuff
pressure and air volumes closely and detect changes
tracheal stenosis s/s - ANS increased coughing, inability to expectorate secretions, dyspnea,
difficulty talking
tracheal stenosis management - ANS tracheal dilation, surgical intervention
