Vasoactive medications are given in all forms of shock. Why are these medications used?
A) To increase myocardial resistance
B) To decrease strength of cardiac contractility
C) To maintain hemodynamic stability
D) To initiate vasoconstriction
Ans: D
Feedback: Vasoactive medications are administered in all forms of shock to improve the patient's hemodynamic stability when fluid therapy alone cannot maintain adequate MAP. Specific medications are selected to correct the particular hemodynamic alteration that is impeding cardiac output. These medications help increase the strength of myocardial contractility, regulate the heart rate, reduce myocardial resistance, and initiate vasoconstriction. Therefore options A, B, and C are incorrect.

B.K.'s respirations become increasingly labored, and you call the rapid response team
While waiting for the team to arrive, you continue a quick assessment, with findings as follows: Lung sounds absent in the LLL and very diminished in the right lower lobe (RLL). You percuss a dull thud over the left middle lobe (LML) and LLL up to the scapula tip. On percussion, you hear resonance over the entire right lung and left upper lobe (LUL). What is the significance of your findings?
