A forced vital capacity is reduced and peak inspiratory flow is reduced

B peak expiratory flow is reduced and peak inspiratory flow is increased

C peak expiratory flow is increased and peak inspiratory flow is increased

D forced vital capacity is reduced and peak inspiratory flow is normal

E peak expiratory flow is reduced and peak inspiratory flow is reduced

Case 2 Hypothyroidism: Autoimmune Thyroiditis
Shirley Tai is a 43-year-old elementary school teacher. At her annual checkup, Shirley complained that,
despite eating less, she had gained 16 lb. in the past year. Her physician might have attributed this
weight gain to “getting older” except that Shirley also complained that she has very little energy, always
feels cold (when everyone else is hot), is constipated, and has heavy menstrual flow every month. In
addition, the physician noticed that Shirley’s neck was very full. The physician suspected that Shirley
had hypothyroidism and ordered laboratory tests (Table 2).
Table 2 Shirley Tai’s Laboratory Values and Test Results
T 4 3.1 ug/dL (normal 5-12 ug/dL)
TSH 85 mU/L (normal, 1.3 – 5 mU/L)
T 3 resin uptake Decreased
Thyroid antimicrosomal antibodies Increased
Based on the physical findings and laboratory results, Shirley’s physician concluded that Shirley had
autoimmune (Hashimoto) thyroiditis and prescribed oral administration of synthetic T 4 (L-thyroxine).
The physician planned to determine the correct dosage of T 4 by monitoring the TSH level in Shirley’s
blood.
Questions
1. Sketch the diagram for the regulation of thyroid hormone secretion by the hypothalamic –
anterior pituitary – thyroid axis. List the two potential mechanisms that could result in
decreased secretion of thyroid hormones and indicate where the problem for each lies on the
diagram. How might you distinguish between these mechanisms as potential causes for
Shirley’s hypothyroidism

A/. A lung with pulmonary fibrosis would exhibit which of the following characteristics?

a. Decreased airway resistance
b. Decreased lung compliance
c. Decreased PVR
d. Decreased surface tension

B. Which of the following indicate a patient is severe decrease in respiratory muscle inspiratory strength?

a. MIP less than -50 cm H20
b. MIP less than -60 cm H20
c. MIP greater than -20 cm H20
d. MIP lower than -20 mm Hg

C.  What is the term for alveolar ventilation without pulmonary capillary perfusion?

a.   alveolar deadspace   c.   minute alveolar ventilation
b.   physiologic deadspace   d.   anatomic deadspace

explain the pathway of blood as it travels through your body starting at the left ventricle

sterol vs steroid explain

TRUE OR FALSE

1.The amount of blood in the ventricles at the end of the ventricular filling phase is the end –systolic volume

2. The first branch of the aortic arch is the brachiocephalic artery, which divides into the left common carotid artery and the left subclavian artery.

3. Tissue perfusion to the heart decreases during systole and increases during diastole

4. Atrial systole is responsible for ejecting most of the blood into ventricles during the ventricular filling phase of the cardiac cycle

5. During heart transplant surgery, an electric shock is sometimes needed to make the donor heart beat properly because the electric shock activates the sympathetic nerve fibers in the ventricles.

6. People with type AB- (negative) blood are universal recipients because they have no antibodies to A, B or Rh in their blood and can receive red blood cells from a donor of any blood type.

1)

A. What is the dicrotic notch from the pulmonary artery catheter wave line?

B. What does nitric oxide do for a mechanically ventilated patient?

C.

When a COPD patient leans forward braced in  ______________________________, this lends particular advantage to the pectoralis accessory muscles of inspiration?

a- an anterior-posterior position
b- a tripod position
c- a prone position
d- a supine position

1. Outline a workflow for the diagnosis of Duchenne Muscular Dystrophy. Include what patient details and material may be assessed and what would be detected/observed at each point of the workflow.

Outline the physiological/pathological processes which can lead to metabolic acidosis and how the body can offset this condition. In your answer discuss any buffer systems utilised and any compensatory mechanisms?

Explain the mechanical and physiological process of breathing in and out during a race. (include the two brain structures that make up the respiratory control centers and the name of the two nerves that regulate the activity of the respiratory muscles in this process)
