Calculate the new anion gap and provide an interpretation of the results. 

For use in ABG syringes, the recommended form of heparin is:

Results of a room air ABG are pH 7.52, PaCO2 10 mmHg, PaO2 153 mmHg. A potential explanation for these values is:

Froth present in an arterial blood gas sample is indicative of:

Potential preanalytical sampling errors include:   Air bubbles in the sample   Venous admixture   Continued metabolism   Improper use of heparin

While do you initial ventilator check on a 6-year-old child you recognize that an infant sidestream capnography adapter was placed in the circuit. This would cause:

The ICU attending inserts a pulmonary artery catheter and you are provided with the following parameters:           PvO2:  25 mmHg           SvO2:   28%           SV:   25 ml

Which of the following features or characteristics apply to mainstream capnography?   The mainstream capnograph contains narrow tubing that can become occluded with mucus.   Mainstream capnography is considered less accurate.   The mainstream capnograph adds weight to the breathing circuit.   The mainstream capnograph is placed at the proximal end of the endotracheal tube.

What is your interpretation of the ABG. Include acid-base and oxygenation status.

An antibody screen is reactive at AHG phase of testing for all cells on a three-cell screen. The autocontrol is negative. What is a possible explanation for these results?
