An 83-year-old male who was on the telemetry unit for a heart failure exacerbation has been transferred to the intensive care unit due to new onset atrial fibrillation with a rapid ventricular response. He was given a diltiazem bolus followed by a continuous diltiazem infusion without successful rate control. It has been less than 48 hours and direct current cardioversion is being considered. The success of electrical cardioversion is inversely proportional to which of the following?

The AG-ACNP is seeing a 70-year-old female patient with a significant history of COPD and 3 months status post right total knee replacement who woke up this morning with severe dyspnea. The chest x-ray was inconclusive of pertinent findings, therefore a CT of the chest was completed. The CT angiogram of the chest was positive for a pulmonary embolism in the right upper lobe. Two hours later the patient’s vital signs changed and she is now tachycardic to 130s, blood pressure 64/48, respiratory rate 30, SaO2 80%. The AG-ACNP identifies this type of shock as:

The AG-ACNP is seeing a patient who is initiating breaths on SIMV. The SpO2 is 98% on 40% fraction of inspired oxygen. The AG-ACNP notices that the patient’s spontaneous tidal volumes are 130 mL per breath, and the patient is getting mildly tachycardic and is complaining of fatigue. Respiratory muscle fatigue can best be reduced by:

A 59-year-old male presents with complaints of chest tightness and shortness of breath. He has a medical history of CAD, hypertension, and hyperlipidemia. Family history is positive for CAD, hypertension, hyperlipidemia, and asthma. His vital signs are: heart rate 110, blood pressure 189/106, respiratory rate 28, and SpO2 96%. On exam the AG-ACNP appreciates bilateral expiratory wheezes, but no rubs, gallops, or murmurs. Capillary refill time is less than 3 seconds. Which medication should be avoided until asthma has been ruled out?
