The correct answer is "urine output, 20 ml/hour".
The minimum urine output for a healthy individual is 30 ml/hour, therefore this measurement of urine output is lower than what is considered acceptable. Urine output is an important assessment which can help the monitoring of renal function. Since the patient is recovering from a renal surgery, a significant low urine output should be reported to the healthcare provider.
In a patient recovering from a surgery, a slight increase in temperature is expected. So is the absence of bowel sounds and a small amount of serous sanguineous drainage.
The correct answer is: the short half-life of edrophonium makes it impractical for long-term.
Edrophonium is used for the diagnostic of myasthenia gravis. In patient with myasthenia gravis, the body produces autoantibodies which inhibit nicotinic acetylcholine receptors in the neuromuscular junction. Edrophonium, on the other hand, is acetylcholinesterase inhibitor which blocks the effect of acetylcholinesterase enzymes (AcH stays in synaptic cleft).
Substitution for the edrophonium is pyridostigmine which is also acetylcholinesterase inhibitor but with long-term maintenance.
