A decreased inspiratory time

A decreased plateau pressure

A decreased peak pressure

A 39-year-old female patient who is intubate was admitted to the emergency department and the nurse was unable to start an intravenous line during CPR.

Which of the following is an alternative route that can be used to deliver this medication?

Through the feeding tube

Aerosolized via SVN

Through the nasogastric tube

Through the endotracheal tube

Normal lungs

Small airway obstruction

Large airway obstruction

Restrictive disease

A 64-year-old female patient with a history of CHF has been admitted to the emergency department on a nasal cannula at 4 L/min. She is coughing up large amounts of pink, frothy secretions and presents the following ABG results: pH 7.42 PaCO2 32 mm Hg HCO3 19 mEq/L BE -3 mEq/L PaO2 46 mm Hg SaO2 81% Which of the following would you recommend?

1-4

4-7

7-10

10-13

A 71-year-old male patient is receiving ventilatory support and it was noted that his secretions are yellow and have gotten thicker over the past 24 hours. The patient has a white blood cell count of 17,000/mm3 and a temperature of 102 °F. Which of the following would you suggest?

Decrease the humidifier temperature

Administer an aerosolized bronchodilator

Schedule suctioning twice per hour

Obtain a sputum sample for culture and sensitivity

DATA: HEMODYNAMICS CVP 4 mPAP 25/5 PCWP 12 VS: 132/80 HR 98bpm VENTILATOR SETTINGS: VT 500ml, MANDATORY RATE 12, TOTAL RATE 14, I TIME: 1.0 SEC, FiO2 30% PEEP+ 5 ABG: pH 7.28 PaCO2 51 torr PaO2 86 torr, HCO3 24 mEq/L BE WHICH OF THE FOLLOWING SHOULD THE RESPIRATORY THERAPIST RECOMMEND?

A 33-year-old was recently diagnosed with influenza. Over the last two days the patient has deteriorated and required intubation. Data: WBC 17K, RBC 6K, K 4.0, Na+ 145, Blood cultures: pending. Gram stain: Gram – rods. CXR: right lung, diffuse alveolar infiltrates and left lung colon opacity in LLL. Which of the following strategies is most appropriate for this patient?

Set VT 6mL/kg IBW

AC– PCV 35cm H20

Start PCV 40cm H2O

An adult patient with a tracheostomy in place is receiving ventilatory support in the volume-control SIMV mode with a set rate of 10/min. Upon assessment, the patient has started to use their accessory muscles during spontaneous breaths. Which of the following would you recommend?

Increase the level of pressure support

Decrease the SIMV rate to 8/min

Switch to the patient to pressure-control SIMV

Switch the patient to a pressure-limited mode

While assessing a mechanically ventilated patient after a neurosurgical procedure, the patient has an intracranial pressure of 20 mmHg but is otherwise stable. The latest ABG results are as follows: pH 7.31 PaCO2 48 mmHg HCO3 24 mEq/L PaO2 88 mmHg SpO2 95% Based on this information, which of the following would you recommend?

Increase the minute ventilation
