Q

Explain COPD to a patient

A

smoking irritates and inflames the lungs resulting in scarring which leads to permanant changes in the lungs. Walls thicken and more mucus produced. Damage to air sacs leads to emphysema.

Or deficiency in a1antirypsin which prevents proteases breaking down lungs

25
Explain a complex partial seizure to a patient
Lose sense of awareness. No memory of event and not able to respond to anyone else.
26
Explain a generalised seizure absence to a ptient
Losing awareness of surroundings. Vacant stare. No memory.
27
Explain a generalised myoclonic seizure to a patient
remain conscious. parts of body twitch or jerk
28
Explain a generalised clonic seizure to a patient.
May lose consciousness. Muscles twitch and lasts longer than myoclonic
29
Explain a generalised atonic seizure
all muscles relax. fall and injure self
30
Explain a generalised tonic seizure
all muscles become stiff, may lose balance and fall
31
explain a generalised tonic clonic seizire
Classic epileptic fit
32
Explain status epilepticus
Any seizure or groups of seizures that lasts longer than 30 mins. Emergency
33
What AEDs do you prescribe for which seizures?
Primary generalised - valproate sodium or lamotrigine Partial seizures - carbamezepine or lamotrigine Pregnancy - lamotrigine
34
What AED do you prescribe for status epilepticus?
lorazepam and iv phenytoin
35
How do you treat gallstones
keyhole or open surgery. Can use ursodeoxycholic acid to dissolve small gallstones that dont contain calcium but this rarely works and takes 2 yrs to work
36
Explain function of gallbladder
contains concentrated bile that is secrdeted to help digest fats
37
How do you screen for gallstones?
CT, MRI, or US
38
How do you treat HF?
beta blockers, ACEi, diuretics, ARBs, digoxin (last resort), anti coagulants and antiplatelets NOT CCBs
39
How do you treat hypertension?
55 yo or black - CCBs | --> +ACEi or CCB --> + diuretics --> +alpha blockers, beta blockers, centrally acting drugs or vasodilators
40
Explain crohns to a patient
inflammation of lining of digestive system. Cann affect anywhere of GI. Disease can enter remission. Cause unknown but could be down to genetics, overactive immune system, environmental factors.
41
how do you treat crohns
croticosteroids to induce remission. immunosuppressants to maintain remission.
42
How would you test for crohns?
Colonoscopy, stool sample (blood and mucus)
43
Explain UC to a patient
Inflammation of large intestine and rectum. Ulcers form
44
What dietary advice could you give to a UC patient?
Drink lots of fluids, avoid alcohol and caffeine, keep a food diary to avoid certain triggering foods
45
How do you treat UC?
aminosalicylates e.g. sulphasalazine to reduce inflammation and get remission. Immunosuppressants to maintain. Surgery - colectomy - to remove large colon
46
Explain vasovagal syncope to a patient
Fainting that comes about due to a reduction in blood flow to the brain, restored when you fall to the floor. Caused by lack of sympathetic drive to tell the blood vessels to constrict and prevent blood pooling in legs. Can occur due to an external trigger such as unpleasnat sight or heat.
47
Explain how you would treat vasovagal syncope
Keep a diary of what could have caused your fainting. Avoid being dehydrated and eat regular meals to avoid hypo.
48
What is a carotid sinus test?
Carotid sinus is massaged whilst lying down to see if it makes you feel faint
49
What are the possible causes of DVT and PE??
Inactivity - causes slowing of blood flow. Surgery - damage to blood vessels BV damage - smoking, hypertension, hyperlipidaemia OCP - pill makes risk of dvt increased
50
How would you treat/prevent a DVT?
Reduce risk with compression stockings and after DVT to prevent recurrence and post DVT damage Exercise Raising legs when resting to relieve pressure on veins in calf Anti-coagulation - heparin or warfarin
51
Explain what the D-dimer test is
blood test to detect peices of blood clots. More fragments = increased risk of blood clot
52
Explain what a venogram is
Dye injected into vein in foot and x-ray used to see dye. Shows blood clots.
53
How would you treat PE?
heparin, warfarin, alteplase
54
What is a ventilation perfusion scan?
Used to examine flow of air and blood in lungs. Patient inhales radioactive gas that highlights air flow of lungs. Radioactive injection also given to show blood vessels in lungs. Test can reveal parts of lungs that have air in them but no blood supply, showing PE.
55
Explain graves diseaes
Overactive thyroid caused by immune system which attacks the thyroid gland and produces lots of thyroid hormones.
56
What can cause hyperthyroidism?
Excess iodine in diet, amiodarone (antiarrhythmic), cancer
57
How do you treat hyperthyroidism?
Carbimazole - ADR is itchiness or joint paint Beta blockers to relieve symptoms of hyperthyroidism Radioiodine - shrinks thyroid gland
58
Explain the thyroid function test
Blood testing for TSH and T3 and T4
59
How would you determine the underlying cause of hyperthyroidism
Radioactive substance swallowed and scan used to see how much of it is absorbed by thyroid. If lots its likely graves. If low it could be due to thyroiditis, too much iodine in diet, thyroid cancer
60
What can cause hypothyroidism?
Autoimmune attacks e.g. hashimoto | Previous thyroid treatment complication
61
How do you treat hypothyroidism?
Thyroid hormone replacement therapy - Levothyroxine
