All of the following are true about adenocarcinoma, EXCEPT:

BONUS: You determine that an acutely ill patient can generate an MIP of –18 cm H2O. Based on this information, what might you conclude?

All of the following disorders cause hypoxemic respiratory failure resulting in an increased A-a gradient, EXCEPT:

Which of the following would you recommend for this patient in the above question?

A patient has a PaO2 of 56 mmHg. Which of the following additional information would be necessary before deciding whether this patient is experiencing hypoxemic respiratory failure? (Select as many as needed).

BONUS: An asthmatic’s airway radius is narrowed by 16% during an exacerbation. Which of the following statements regarding the mechanics of ventilation is true? (Think back to A&P on ventilation).

An alert patient in hypercapnic respiratory failure presents with dyspnea, diminished breath sounds, tachypnea and mild to moderate accessory muscle use. These findings best fit which cause of respiratory failure?

A nurse hands you ABG results and asks you to explain what is happening to his patient. The ABGs are: pH 7.32, PaCO2 52 mmHg, PaO2 56 mmHg, HCO3 30 mEq/L. Which of the following best describes this ABG?

A CHF patient’s ABGs on 60% oxygen are pH 7.48, PaCO2 32, PaO2 56, HCO3 23.4 with a RR = 30 bpm. The patient is complaining of SOB. The patient states that they have never smoked and diffuse late fine inspirtory crackles are auscultated. The nurse has administered a dose of furosemide (Lasix) and digoxin (Lanoxin) per the physician’s order. Knowing that medications to treat the CHF will begin working within the next two hours, which of the following would you choose to improve oxygenation?

A post-op patient is admitted to ICU in respiratory distress. He fell out of his deer stand onto his four-wheeler, suffering chest and abdominal trauma. He has increased work of breathing and you hear late fine crackles bibasilar with an SpO2 of 88% on RA. On a 50% air entrainment mask the patient’s PaO2 increases to 138 mmHg
