MA Quiz 2 Chapters 10,11,16,18-24

Question 1

Normal Temperature Ranges
Oral:
Rectal:
Axillary:
Tympanic:

Answer 1

Oral: 97.6-99.6
Rectal: 98.6-100.6
Axillary: 96.6-98.6
Tympanic: 98.6-100.6 (similar to rectal range)

Question 2

What are the 3 phases in the process of healing?

Answer 2

INFLAMMATORY, GRANULATION, CONTRACTION

1. inflammatory phase: fibrin network forms then clotting and finally scab
2. granulation phase (aka fibroblastic phase): granulation tissue (new connective tissue and tiny blood vessels) absorb fluids, epithielial cells form and scar results
3. contraction phase (maturation phase): small blood vessels absorbed and fibroblasts contract; scar shrinks and becomes lighter

Question 3

List a few ways to close wounds

Answer 3

stapling, application of adhesive tapes (for surface wounds), stitches/sutures

Question 4

What is used to study pregnant women?

Answer 4

Ultrasounds (sonograhpy: high frequency sound waves bouncing off internal body structures to form a composite picture; display movement of structure at time of examination).

Question 5

What is the purpose of the ultrasound?

Answer 5

Ultrasound is performed on pregnant women to assess fetal growth and size, number of fetuses, placental location and possible birth defects. Also can check for fluids.

(FYI: baby receives nutrients through umbilical cord which is attached to the placenta)

Question 6

What are cautions to take before a MRI scan?
Ineligibility:
Take off:
Avoid:

Answer 6

Ineligibility: patients with pacemakers, metal hardware, metal staples, metal foreign bodies in the eye (pacemaker can be damaged or settings may be disrupted; metal implants may be dislocated)

Take off: jewelry

Avoid: movement

Question 7

Respiration consist of these 2 processes

Answer 7

inhalation and expiration

Question 8

What is the purpose of the skin

Answer 8

Skin serves several bodily functions including:

• barrier to prevent microorganisms/foreign bodies from entering
• temperature regulator
• protection against dehydration
• environment sensor (pain, temperature and touch)
• synthesizing vitamin D from sunlight
• excreting toxins in perspiration

Question 9

Pituitary gland releases what hormones?

Answer 9

Hormones secreted:

• growth hormone: stimulates growth, protein synthesis, lipid mobilization and catabolism
• thyroid-stimulating hormone: stimulates secretion of thyroid hormones
• adrenocorticotropic hormone: glucocorticocoid secretion
• follicle-stimulating hormone: stimulates estrogen secretion and follicle development (f) and sperm maturation (m)
• luteinizing hormone: stimulates ovulation, corpus luteum development, secretion of progestrone

Question 10

Blood Pressure: top/bottom ?

Answer 10

systolic/diastolic w normal bp of adult: 120/80

Question 11

What is Graves’ disease?

What is hyperthyroidism?

Answer 11

Hyperthyroidism, oversecretion of thyroid hormones, is also known as Graves’ disease. Symptoms include nervousness, excessive perspiration, insomnia, palpitations, intolerance to heat.

Question 12

What is the MA role in emergency care?

Answer 12

Roles include: transport if necessary, baseline vitals (bp, temperature, pulse), assessing pain/injury

Question 13

What is a protein?

Answer 13

Protein is a food component composed of amino acids; provides source of energy and assists in building and renewing body tissues.

Question 14

Description of pulse

Answer 14

Normal pulse: 60-100bpm

Question 15

What is the MA’s role in MRI?
