This heavy metal has both an essential form and a toxic, nonessential form. When absorbed it will be bound by transferrin and transported by albumin.
Chromium
Over the decades, this element has been considered a toxic element, a carcinogen, essential element, and an anti-carcinogen. It is also involved in the metabolism of thyroid hormones.
Selenium
A vitamin _________ is due to either inadequate diet, inadequate GI absorption, competing organisms (parasites).
Deficiency
This deficiency in this vitamin is associated with hair loss, anorexia, and depression. It is often found in hair products and supplements. Taking supplements that contain this may cause interference with certain test assays.

What is not a reason to order/perform a myoglobin test?
Dehydration
The most common abnormalities in the structure of hemoglobin is:

Which of the following is a qualitative screening test for porphobilinogen that may be performed to aid in the diagnosis of the porphyrias?
Watson-Schwartz test
Which of the following will lead to decreased serum levels of creatinine in the geriatric patient? Decreased muscle mass, increased GFR, decreased protein inktake, none fo the above
Decreased muscle mass
Which could account for drug toxicity following a normally prescribed dose to the geriatric patient? Decreased renal clearance, slowing of drug absorption, liver impairment, all of the above
All of the above
All of the following represent normal physiology of the newborn except: weight of 2.1 kg, immature liver function and inability to elimate excess bilirubin, infants normally rapidly adapt by initiating active respiration, 4-6 months for the infants body weight to double
Weight of 2.1 kg
Which is not a test typically included on a newborn screening panel in the U.S.
Cholesterol
What type of tissue is the hormone releasing islets of Langerhans?
Endocrine

Delta
Which enzyme test is almost exclusively a pancreatic test and increases within 24 hours for acute pancreatitis?
Lipase
What test is a direct termination of the exocrine secretory capacity of the pancreas?

Patients with toxicity of this element often have anxiety along with bouts of compulsive laughing and crying.
Manganese
What is the primary plasma iron transport protein
Transferrin
This element is widely used in industry and household ways. It also is associated with anemia, bone disease, and progressive dementia.
Aluminum
Given these lab results, what would an expected condition be: transferrin decreased, ferritin increased, % saturation increased, TIBC decreased
Iron overdose
This element has gone through quite the identity crisis over the decades being seen as a toxic element, a carcinogen, essential element, and anti-carcinogen.
Selenium
T/F: heel stick and venipuncture blood is identical in composition.

T/F: Drug dosing and interactions are something that needs to be watched more closely in a geriatric patient for several reasons.
TRUE
T/F: Calcium and Aldosterone increase in value in a geriatric patient
