A 32-year-old patient was admitted to an urgent care facility with tachypnea, complaining of light-headedness. The patient disclosed a positive history of anxiety with panic attacks. Arterial blood gas was obtained with the following results: pH: 7.44 | PaCO2: 28 | HCO3: 20. The AGACNP interprets these results as:

A 50-year-old patient was admitted to the emergency department complaining of shortness of breath, fatigue, and non-productive cough for the past 3 days. On admission the patient temperature was 38.6 degrees Celsius. Vital signs were remarkable for hypotension (100/72 mmHg), tachycardia (110 bpm), and a respiratory rate of 21. The pulse oximetry on room air revealed a SpO2 of 85%. The AGACNP assessing this patient is interested in knowing the possible etiology of the patient’s hypoxemia. An age adjusted A-a gradient will help in the process of evaluating the source.   The AGACNP performs the calculation and finds the following value for age expected A-a ratio:  

A 68-year-old male presents to the emergency department with a 3-day history of productive cough, fever, pleuritic chest pain, and shortness of breath. He has a history of hypertension and type 2 diabetes. On exam, he is febrile (38.9°C), tachypneic (RR 26), and has crackles in the right lower lung field. SpO2 monitoring reveals an oxygen saturation of 90% on room air.  Chest X-ray shows a right lower lobe infiltrate. What is the most appropriate next step in management?

A 68-year-old male is brought to the ED via emergency medical services after a syncopal episode at home.  He was conscious upon their arrival at his home and was complaining of chest discomfort.  At the time of the EKG recording, he complained of near syncope and chest burning.  His EKG is seen here.

FIO2 0.65 Mandatory rate 14 VT 450 mL PEEP 8 cm H2O The therapist notes the following pressure-volume tracing:  The therapist should recommend decreasing the    

A patient complaining of dyspnea has a heart rate of 112/min and a respiratory rate of 28/min. The following ABG analysis results are obtained while the patient is receiving oxygen at 5 L/min by nasal cannula: ABG: pH 7.47 PCO2 33 mm Hg PO2 48 mm Hg HCO3 – 24 mEq/L BE +1 mEq/L SO2 (calc) 83% Which of the following should be done FIRST?
