Members of Archaea are often referred to as extremeophils because they live in conditions of extreme:

In order for a milk protein to be secreted, its mRNA must first be translated on ribosomes:

There are several children in the Emergency Department (ED) waiting room with complaints of asthma.  The triage nurse has only one room left in the ED.  Which child should receive priority admission?  

The patient is receiving continuous IV sedation and is mechanically ventilated with Assist/Control. Which of the following interventions should be prioritized to minimize the risk of complications associated with sedation in this patient?

A 32-year-old patient with acute respiratory distress syndrome (ARDS) is mechanically ventilated with the following settings: Mode: Assist-Control (AC) Tidal Volume (VT): 450 mL Respiratory Rate (RR): 18 breaths per minute FiO2: 0.80 (80%) PEEP: 12 cm H2O Peak inspiratory pressure: 40 cm H2O The patient’s most recent arterial blood gases (ABGs) show the following: pH: 7.28 PaCO2: 56 mm Hg PaO2: 65 mm Hg HCO3: 28 mEq/L SaO2: 90% Which of the following interventions would the nurse anticipate to improve this patient’s oxygenation and ventilation?

A 68-year-old patient with acute respiratory distress syndrome (ARDS) is on mechanical ventilation with the following settings: Mode: Assist-Control (AC) Tidal Volume (VT): 400 mL Respiratory Rate (RR): 14 breaths per minute FiO2: 1.0 (100%) PEEP: 10 cm H2O Peak Inspiratory Pressure: 45 cm H2O The most recent arterial blood gases (ABG) show: pH: 7.30 PaCO2: 62 mm Hg PaO2: 72 mm Hg HCO3: 30 mEq/L SaO2: 92% Given these results, which of the following is the priority nursing action?

Your patient with ARDS converts into atrial fibrillation with RVR in rates of 140s. An infusion of lidocaine (Xylocaine) is prescribed at 1.3mg/min. The concentration of the medication is 1 g in 500 mL of IV fluid. Determine the flow rate in mL/hr. (Round to the nearest whole number when calculations are complete)

After 4 days of mechanical ventilation with ARDS, the patient’s PaO2 remains at 83 mm Hg despite the current ventilator settings. What is the nurse’s best evaluation regarding the patient’s response to therapy?  

Based on these findings, which of the following is the most appropriate interpretation of her oxygenation status?

A patient on mechanical ventilation is being assessed by the nurse. Review the following settings on the ventilator screen. The nurse observes that the patient is triggering the ventilator more frequently than the set respiratory rate. What is the most appropriate nursing intervention at this time?
