Hey everyone,
I have a couple of questions that I need to verify answers for:
1. A 60yr old man who has weakness/light-headedness. His diet= fruits, veggies, whole grains, lean chicken and fish. 10 yr history of Hashimoto thyroiditis treated w/ thyroxine. He has pallow, increased methylmalonic acid and total homocysteine. He has megaloblastic anemia. What is the cause?
cystathion beta-synthasse deficiency (nope)
failure of IF production
Folic acid deficiency
Helicobacter pylor gastritis
Methylmalonyl-Coa Mutase deficiency (im guessing this is the answer?)
2. 10 yr old boy with type 1 diabetes is receiving insulin. One hour after his morning dose he becomes tremulous and diaphoretic and has tachycardia. Several hours later his symptoms resolve. What is the cause of the patients hyperglycemia?
activation of hepatic adenylyl cyclase (is this the answer?)
activation of muscle glycogen synthase
activation of muscle phosphorylase (why couldnt this be the answer?)
activation of muscle protein phosphatase (nope)
inhibition of hepatic protein kinase A
3. 15 yr old boy brought due to behavioral changes. Hes failing school. Pulse 110, rr 24/min, bp: 140/85. Pupillary dilation and diaphoresis. His affect is agitated and his thought process is confused. What is he intoxicated with?
Alcohol
amphetamine
amyl nitrate (is this it? Is he huffing glue?)
cannabis (nope)
heroine
4. Leading cause of death in women--> is it cardiovascular disease? I feel like I had a complete brain fart on this one.
Thanks in advance.
