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.

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage. This occurs without any major symptoms until the high blood pressure becomes extreme. Regular blood pressure checks are an important method of catching hypertension before it can kill you.
