Starts cardiopulmonary resuscitation.

B. Ventilates the client manually.

A patient has developed acute respiratory distress syndrome (ARDS) and requires mechanical ventilation. Which respiratory complications would the nurse assess for in this patient? Select all that apply. Barotrauma Pneumothorax Pulmonary hemorrhage Decreased cardiac output Ventilator-associated pneumonia

Barotrauma Pneumothorax Ventilator-associated pneumonia

The nurse should intervene when a patient who is being admitted to the unit with the diagnosis of COPD is noted to have which clinical manifestation? Confusion Cough Depression Fatigue

Confusion (Patients experiencing hypoxia usually have signs of irritability, restlessness, anxiety, and confusion. As the brain cells receive less oxygen, thepatient becomes more confused)

A patient who is receiving mechanical ventilation is at risk for which complications? Hypotension, infection, and barotrauma Anxiety, hypertension, and fatigue VAP, atelectasis, and hypothermia Dyspnea, hypoxia, and normothermia

Hypotension, infection, and barotrauma (Hypotension: Secondary to changes in the pressure in the chest cavity. This increased pressure in the chest causes a decrease in venous return and can ultimately decrease CO. Infection: Because the normal defense of the upper and lowerairways are bypassed. The ETT leads directly into the lungs and can introduce infection. Barotrauma: Due to the increased positive pressure that cancause alveolar rupture)

The nurse maintains the head of the bed elevated for a patient on mechanical ventilation. What neurologic disorder is the nurse attempting to reduce the risk of? Guillain-Barré Multiple sclerosis (MS) Traumatic brain injury (TBI) Increased intracranial pressure (ICP)

Increased intracranial pressure (ICP)

A patient on mechanical ventilation is given esomeprazole via a gastric tube. The nurse knows that this prophylactic treatment is important because of which associated risks? Select all that apply. Sedation Immobility Decreased peristalsis Decreased air swallowing Increased acid production

Sedation Immobility Decreased peristalsis Increased acid production

a nurse treats a client admitted w severe frostbite. which assesssmnet finding does the nurse expct to make excessive exudate increased perfusion loss of sensation sensitive skin

loss of sensation

a client sustains majjor burns on the anterior thorax, head and bilateral upper extremities following a house fire. whats the inital treatment goal for this clieint? maintain patent airway prevent infection restore hemodynamic stability resuscitate intravascular fluid

maintain patent airway

In assessing a patient's arterial blood gases, who is diagnosed with earlystage acute respiratory failure, the nurse would expect to see which of thefollowing results? pH 7.48, PaCO2 44mm Hg, HCO3 30mm Hg,PaO2 70mm Hg, SaO2 94% pH 7.34, PaCO2 40mm Hg, HCO3 18mm Hg,PaO2 74mm Hg, SaO2 98% pH 7.48, PaCO2 30mm Hg, HCO3 26mm Hg,PaO2 52mm Hg, SaO2 90% pH 7.38, PaCO2 48mm Hg, HCO3 24mm Hg,PaO2 88mm Hg, SaO2 96%

pH 7.48, PaCO2 44mm Hg, HCO3 30mm Hg,PaO2 70mm Hg, SaO2 94% (In the early stages of acute respiratory failure the nurse would anticipate that the client's respiratory rate is elevated and oxygenation would be decreased, resulting in a respiratory alkalosis with hypoxemia.)

the nurse knows it is essential to have which piece of equiptment at the bedside of a pt receiving mechanical ventilation resuscitation bag incentive spirometer particulate respirator patient controlled analgesia

resuscitation bag

a client w a circumferencial full thickness burn to the chest reports chest tightness. the nurse assesses for which desired outcome of an escharotomy debrided infected tissue reduced arm edema reduced scarring return of circulation distal to the burn

return of circulation distal to the burn

the triage nurse assess a client w burns on the R arm and leg, the client is crying w pain, the skin is red and large wet blisters are present. which depth of injury does hte nurse suspect deep partial thickness full thickness superficial superficial partial thickness

superficial partial thickness
