ACE YOUR NUR 2356 MDC4 EXAM: COMPLETE STUDY GUIDE WITH
COMPREHENSIVE QUESTIONS AND ANSWERS LATEST 2026/2027
◍ what does high alarm on ventilator mean.
Answer: kink in tubing or water blocking tube kink in ET tube or pt biting it
◍ why should the nurse question an order to set TV at 10ml/kg.
Answer: this is too high, could cause volutrauma, should be set at 6ml/kg
◍ a pt on SIMV mode begins to breath rapid, what should you do.
Answer: check for pain, anxiety, hypoxia
◍ what will you see on assessment of someone with atelectasis.
Answer: increased work of breathing hypoxemiadecreased breath
soundscracklesinfiltrates or consolidation on xray
◍ Infection Prevention.
Answer: Measures to prevent spread of infections.
◍ 4th degree burn area affected.
Answer: damage extends to muscle, tendon, and bone
◍ pleural effusion.
Answer: fluid accumulates in the pleural space and separates air filled lungs
from the chest wall, blocking breath sounds
◍ ventilator asynchrony nursing action.
Answer: reassess sedationcheck settingsrepositionsuction if needed
◍ tension pneumothorax tx.
Answer: immediate tension decompression
◍ how do you confirm ETT placement.
Answer: CXRAY and mark tube depth at lips or naresreposition tube and
securement device every 2 hours to prevent pressure injuries
◍ causes of hypercapnic resp failure.
, Answer: neuromuscular disorders- MG, GB, ALS, SCICNS issues- drug
OD, head trauma, infection, hemorrhage, sleep apnea, anesthetics and
sedativesMSK dysfunction- kyphoscoliosis, chest trauma,
malnutritionpulmonary dysfunction- COPD, asthma, CF
◍ oxygen toxicity action.
Answer: collaborate to wean FiO2 to lowest effective level, monitor for
ARDs signs
◍ causes of hypoxemic resp failure.
Answer: pneumoniapulmonary edemaARDSCOPDasthmarestrictive lung
diseaseHFPE
◍ atelectasis.
Answer: closure or collapse of alveoli
◍ 2nd degree burns damage:.
Answer: superficial partial: entire epidermis and some of dermisdeep partial:
burns extend deeper into the dermis
◍ lobar vs broncho pneumonia.
Answer: lobar- involves entire lobebroncho- patchy infection involving
multiple areas of one or both lungs
◍ flail chest hallmark sign.
Answer: paradoxical chest movement
◍ when do you perform suctioning.
Answer: adventitious breath soundsvisible secretionsdecreased oxygen
saturation
◍ cues of a sternum vs rib fracture.
Answer: ribs: severe pain, point tenderness, muscle spasm,
echhymoisissternum: anterior chest pain, ecchymosis, crepitus, swelling,
chest wall deformity
, ◍ goal of sedation in ARDS for a pt on ventilator:.
Answer: minimize pt-ventilator dyssynchrony
◍ key indicators of hypoxemic resp failure.
Answer: dyspneatachypneacentral cyanosisrestlessness or
agitationtachycardiadecreased PaO2 <60possible normal or low PaCO2
◍ what are the three zones of injury for each burned area.
Answer: innermost area: zone of coagulationmiddle area: zone of
stasisoutermost area: zone of hyperemia
◍ function of the cuff on an ETT or tracheostomy.
Answer: prevents aspiration and facilitates ventilation
◍ Integumentary.
Answer: System including skin, hair, and nails.
◍ hypercapnic respiratory failure.
Answer: occurs when the lungs cannot remove carbon dioxide effectively,
often due to ventilatory failure
◍ tension pneumothorax.
Answer: life threatening, severe form of pneumothoraxwhere air enters the
pleural space but cannot escape, causing increasing pressure, lung collapse,
mediastinal shift, and obstructive shock
◍ defining characteristics of ARDS.
Answer: acute onset (within 7 days of insult)refractory hypoxiabilateral
pulmonary infiltratesreduced lung compliancenoncardiac related pulmonary
edema
◍ how to prevent hypertrophic scars after a burn.
Answer: compression/pressure garments
◍ Tuberculosis.
Answer: Contagious bacterial infection affecting lungs.
