Which of the following, using Wright stain, is a feature of normal cells as they mature?
a. Overall size increases
b. Nucleoli become more prominent
c. Nuclear chromatin becomes more condensed
d. Cytoplasmic basophilia increases
ANS: C
Nuclear chromatin is initially diffuse or dispersed; as a cell matures, the chromatin undergoes a process of condensing and stains more intensely with Wright stain. The overall cell size decreases; nucleoli are no longer visible if even present, and cytoplasmic basophilia, present because of the high concentration of RNA in a young cell, decrease.

The administration of an antiplatelet drug increases the risk of:
A) heartburn B) kidney failure C) bleeding D) angina pectoris
Despite the risk, it is still important to use PEEP, because it can prevent alveolar collapse during exhalation and reopening, even when a low VT is used. It now is theorized that it is important to use the pressure-volume loop to set PEEP _______________
