Answer to Question 1

A
Feedback:
Because vecuronium is structurally similar to ACh, it binds to the receptors on the muscle and prevents normal function of ACh, producing skeletal muscle paralysis. The drug does not influence the physiology of serotonin, the cerebellum, or acetylcholinesteras e.

Answer to Question 2

A
Feedback:
Decreased pedal edema improves cardiac output due to the fact that the patient has diminished fluid volume. Increased skin turgor indicates that the patient is well hydrated and does not have fluid volume excess. A heart rate of 52 is too slow to provide good contractility. Improved sensorium indicates adequate perfusion but is not the most indicative of improved heart failure status.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
