Q

T3 has what impact on the cardiac system?

A

T3 stimulates contractile protein and ion pumps (N+/K+ ATPase; Ca++ ATPase; and ß-adrenergic receptors).

This relationship can lead to heart failure if thyroid levels are imbalanced.

A

Answer choice: E (one or more of the above)

In primary hypothyroidism the issue is from the thyroid gland itself, because the T3/T4 are low** and the feedback mechanism **elevates TSH, but the thyroid will not respond.

Q

Which of the following symptoms are consistent with DKA?

A) Low sodium

B) Usually seen in Type II DM

C) Low potassium

D) hypoventilation

A

Answer: C (low potassium)

Other S&S of DKA include: Kussmaul respirations (hyperventilation), CNS depression, N/V, acetone breath, thirst, polyuria.

Lab values: pH <7.3, Bicarb <18, Glu >250; elevated anion gap

94
Q

What disease process does this scenerio describe:

Poor glucose control causes an elevated glucose level, followed by increased serum osmotic pressure and osmotic diuresis.

A

Hyperosmolar Hyperglycemic Nonketotic Syndrome (HHS)

95
Q

In DKA a _______ (lack/excess) of insulin causes other hormones such as _____ to be released to provide the body with alternative forms of energy.

A

Answer: lack of insulin will cause hormones such as glucagon to be released.

DKA can lead to metabolic acidosis and coma

Risk factors include: illness, trauma, sx, MI, med noncompliance, ethnic, lack of insurance, low BMI

96
Q

True or false, hyperosmolar hyperglycemic nonketotic syndrome is seen more in diabetes type I?

A

False. It is more common in DM type II and the elderly.

It can cause dehydration, low BP, poor perfusion as the osmotic diuresis increases.

97
Q

Glucose 650, bicarb 24, serum osmol >320, pH 7.40. Which diagnosis would the NP give this patient?

A)Cushing disease

B)Uncontrolled DM type I

C)Hyperosmolar hyperglycemic non-ketotic syndrome (HHS)

D) DKA

A

Answer: C (HHS)

In HHS glucose will be >600, bicarb will be normal, serum osmol >320, and no ketones will be present.

Glycosuria and polyuria can cause volume depletion and electrolyte issues including K+ and neurological changes.

98
Q

True or false, a loss of electrolytes such as K+ can have neurological impacts?

A

True. This is seen in hyperosmolar hyperglycemic non-ketotic syndrome.

99
Q

What term(s) would be an accurate diagnosis for this scenario:

Early morning blood sugar rise caused by nighttime elevation in growth hormone (which decrease metabolism of glucose)?

A

Dawn phenomenon

100
Q

What term(s) would be an accurate diagnosis for this scenario:

Hypoglycemia at 0300 caused by NPH given at dinner, followed by rebound hyperglycemia due to early morning secretion of counter-regulatory hormones which stimulate gluconeogenesis.

A

Somogyi Effect

101
Q

Microangiopathy is seen in which areas:

A) retina

B) nerves

C) kidney

D) brain

A

Answer: A,B,C

Microangiopathy is atherosclerosis in small vessels due to elevated glucose. It is seen ~10 years after a diagnosis.

102
Q

True or false, microangiopathic ischemia and oxidative stress would cause: autonomic neuropathy and peripheral neuropathy?

A

True. Peripheral neuopathy increases injury risk whereas autonomic involves the GI (slows motility), bladder (incontinence), heart (silent MI).

103
Q

True or false, macrovascular injury would impact the kidney, nerves, and retina?

A

False. Macrovascular injury involves the brain, heart (aorta), femoral arteries. The elevated glucose causes atherosclerosis in small/medium vessels.
