A) A diastolic blood pressure that is lower during exhalation
B) A diastolic blood pressure that is higher during inhalation
C) A systolic blood pressure that is higher during exhalation
D) A systolic blood pressure that is lower during inhalation
Ans: D
Feedback: Systolic blood pressure that is markedly lower during inhalation is called pulsus paradoxus.
