Answer to Question 1

D
A change in blood pressure that is more than 10 mm Hg lower on inspiration than on expiration is known as pulsus paradoxus. This exaggerated waxing and waning of arterial blood pressure can be detected with a sphygmomanometer or, in severe cases, by palpating the pulse at the wrist or neck. Commonly associated with severe asthmatic episodes, pulsus paradoxus is believed to be caused by the major intrapleural pressure swings that occur during inspiration and expiration.

Answer to Question 2

C
After an asthma attack, there will be an increased eosinophil count. The other types of white blood cells will be increased with a bacterial infection.
