Answer to Question 1

ANS: C
The breaths shown are both patient triggered. Negative deflections on the pressure-time scalar are present for both complete breaths shown. There is also a negative deflection between the two that did not result in a ventilator breath. A closer look at the amount of pressure required to trig-ger a ventilator breath shows that it is set too insensitive. In this situation the patient needs to generate a pressure of 10 cm H2O below the baseline to trigger a breath. The negative deflection in the center of the pressure-time scalar demonstrates that the patient could not generate enough negative pressure to trigger a breath. Therefore, the sensitivity is not set properly.

Answer to Question 2

ANS: D
When the volume drops below the baseline during exhalation, the cause could be active exhala-tion or an inspiratory time that is too long. Assessing the patient for active exhalation is the only viable answer given the choices. By doing the assessment the respiratory therapist can determine whether active exhalation is the cause.

Vampire bats have a natural anticoagulant in their saliva that permits continuous bleeding after they painlessly open a wound with their incisors. This capillary blood does not cause any significant blood loss to their victims.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.

Hippocrates noted that blood separates into four differently colored liquids when removed from the body and examined: a pure red liquid mixed with white liquid material with a yellow-colored froth at the top and a black substance that settles underneath; he named these the four humors (for blood, phlegm, yellow bile, and black bile).
