The type of diarrhea that may involve loss of blood, mucus, and plasma proteins is:
Secretory diarrhea
Exudative diarrhea
Osmotic diarrhea

Which of the following is not true about thalassemia?
Ineffective erythropoiesis leads to decreased plasma volume
May result in facial deformities
Inherited
May result in osteomalacia
Ineffective erythropoiesis leads to decreased plasma volume
In thalassemia, there is ultimately increased iron absorption and progressive iron deposition in tissues, resulting in oxidative damage
Calcium is tightly regulated in the body. Which of the following is one of the ways calcium is tightly regulated?
PTH signals the body to produce calcium
Calcitonin increases calcium absorption in the small intestine
PTH increases bone resorption
PTH and calcitonin work together to increase calcium when calcium is low.
PTH increases bone resorption
Where serum calcium is LOW, the parathyroid glands release PTH which signals the bone, kidneys, and small intestine to breakdown stored calcium and/or increase calcium absorption. When serum calcium is HIGH, calcitonin is released to store calcium in the bones

The primary action of norepinephrine is to:
Regulate blood flow, maintain muscle tone, and gastric motor activity.
Decrease motility, increase contraction of sphincters, and inhibit secretions
Increase sensory awareness and peristalsis
Relax the LES
Decrease motility, increase contraction of sphincters, and inhibit secretions
Norepinephrine is released to stimulate flight or fight response in times of stress - opposite of rest/digest
Which of the following hormones acts on the hypothalamus to signal satiety?
Adiponectin
Leptin
Ghrelin
Epinephrine
Leptin - mostly produced by adipocytes. In obesity, excess fat stores may contribute to chronically elevated leptin levels
Which of the following vitamins is required in the PPP for transketolase reactions?
B3
B1
B2
B6
B1 - transketolase is a thiamine pyrophosphate (b1) dependent enzyme.
What happens in the distal convoluted tubule?
Filtrate is collected and nutrients including amino acids, glucose, electrolytes, and fluids are reabsorbed.
Renal filtrate is “fine tuned” through water and sodium reabsorption. Responds to changes in hormones (ADH and aldosterone). Maintains blood pressure.
Reabsorption id water, Na, K, and Cl
Reabsorption of water only
Renal filtrate is “fine tuned” through water and sodium reabsorption. Responds to changes in hormones (ADH and aldosterone). Maintains blood pressure.
A clients recent bloodwork indicates high serum homocysteine. You make a note to educate this client that this means they may be at an increased risk for a number of conditions and disease. These do not include/
