Answer to Question 1

B
Feedback:
Most reabsorption occurs in the proximal tubule. Almost all glucose and amino acids are reabsorbed; about 80 of water, sodium, potassium, chloride, and most other substances is reabsorbed. Arterial blood enters the glomerulus by the afferent arteriole, and blood that does not become part of the glomerular filtrate leaves the glomerulus through the efferent arteriole. The ureters connect the kidneys to the bladder.

Answer to Question 2

D
Feedback:
Epinephrine is not given orally because enzymes in the GI tract and liver destroy it. The medication can be given through inhalation, intravenously, and subcutaneously. The medication will work more quickly in a parenteral form but is not given orally. Stating to the patient that this method is the way the physician ordered it to be given will belittle the patient and not provide adequate patient teaching.
