36
Q

What is the primary treatment for hypothyroidism

A

Replacement of thyroid hormone -dot commonly prescribed is levothyroxine (synthroid)

*bradycardic and hypotensive , hypoglycemia and hyponatremia develop

39
Q

What types of medications have to be closely monitored if given to a patient with hypothyroidism

A

Sedatives, hypnotics and narcotics because the metabolism of the medication is slower and respiratory compromise may occur with normal dosages

40

A

Generalized nonpitting edema, particularly in the hands, feet, between the shoulder blades and around the eyes - edema of the tongue and around the larynx results in changes in speech and a husky tone

Women age 20-40

43
Q

46
Q

Lab values in a patient with hyperthyroidism would reflect what

A

Elevated T3 and T4 - decreased TSH

47
Q

A

Hypocalcemia

Numbness , tingling around mouth or hands and feet , severe muscle cramps , spasms of hands and feet and tetany

48
Q

Normal range of magnesium

49
Q

Normal range of phosphorus

50
Q

Two specific assessments observed in hypocalcemia are

A

Chvostek’s - abnormal reaction to stimulation of facial nerve

Trousseau’s - an indication of latent tetany in which carpal spasm occurs when the upper arm is compressed

51
Q

Diagnostic results consistent with hypoparathyroidism

A

Low calcium, high phosphate, low PTH

52
Q

Clinical manifestations of hyperparathyroidism

A

Polyuria , anorexia , constipation and generalized bone pain

53
Q

Diagnostic results consistent with hyperparathyroidism

A

High PTH and high ionized Ca

54
Q

Which type of diuretic should be avoided in patients with hyperparathyroidism

A

Thiazide diuretics because they increase absorption of Ca in the kidney

55
Q

Type 1 diabetes

A

Autoimmune process in which the insulin-producing beta cells of the pancreas are destroyed , resulting NO insulin

**requires insulin therapy
