One of the aides is taking pharm, and suggests that this patient might need a diuretic. What do you think?
an osmotic diuretic might help this patient excrete water and correct their imbalances
A potassium-wasting diuretic would be the best choice to correct this patient's imbalances
A diuretic is just the wrong choice, this patient needs nasal ADH spray
It would make more sense to give this patient ACE inhibitors to correct their electrolyte imbalances

A person has a condition in which their endocrine system overproduces Antidiuretic Hormone (ADH). This hormone affects the function of the kidneys, which is part of the excretory system. If you were a doctor treating this patient, which symptom would be unusual for this patient? 
frequent urination
dehydration
fluid buildup in tissues
extreme thirst

In the process of deamination, the liver converts amino acids into compounds
that can be used in energy metabolism. The liver removes the amino groups from
amino acids to produce urea. Then, the urea is removed from the body as urine.
During this process, the liver works in conjunction with which body system? *
A. Endocrine
B. Excretory
C. Nervous
D. Respiratory
