General Practice Flashcards
what type of drug is methotrexate
DMARD
what drug type is aspirin?
NSAID
when may you co-prescribe folic acid?
patient on methotrexate
what part of the kidney does ramipril dilate?
Efferant arteriole
what investigation may be needed for a patient on methotrexate?
FBC: marrow/wbc suppression
LFT: liver toxicity can occur
U&E
what is the risk of long term aspirin and what medication should be offered?
risk of gastric ulcers, offer patient a PPI
risks of methotrexate medication
- GI toxicity (diarrhoea)
- liver toxicity
- pulmonary toxicity (SOB)
what term is used to describe a high level Hb
polycythaemia
what can a raised ALT and GGT indicate?
liver damage - typically with GGT think alcohol consumption
causes of polycythaemia
primary = polycythaemia vera (JAK2 gene mutation)
secondary = sleep apnoea, COPD, chronic HD, anabolic steroids
apparent - diuretics, alcohol, obesity
causes of macrocytosis (name 2)
- B12 folate def
- alcohol
- drugs - methotrexate
- haem disorders - e.g. myeloma
- liver disorder
- smoking
- obesity
causes of Hypocalcaemia - 2
decreased PTH - low vit D CKD - liver disease - sclerotic bone metastasis
causes of raised GGT and/or ALT (2 for each)
-GGT
alcohol
- obesity
-pancreatic disease
ALT - statins - NSAID - hep B&C - coeliac a1at defificiency haemachromatosis
what is the affect of alcohol on ferritin?
alcohol increases ferritin
what must be checked before starting a patient on a bisphosophonate
- can they sit up and take medication
- calculate the creatinine clearance make sure good enough
why is bisphosponate treatment limited
early reduction in bone resorption followed by later reduction = micro fractures
what class of drug is metoclopramide
anti-emetic - speeds up gastric motility/output and acts on dopamine receptors = less feeling of sickness
what type of drug is naproxen
NSAID
a pt Bp is 142/61 what stage of hypertension is this?
stage 1
what may you assess/investigate if looking for end organ damage in a hypertensive pt (4)
- fundoscopy -> retinopathy
- urinalysis -> albumin:creatinine (how leaky kidneys are)
- 12-lead ECG (high bp=LVH?)
- QRISK3 (stroke risk)
why must you re-assess a HTN pt’s Bp 2 weeks after prescribing an ACEi for their HTN
increase in AKI symptoms - suggestive of renal artery stenosis as cause of HTN
what murmur may be heard in severe anaemia
flow murmur
what is the bp reading for stage 3 HTN
> 180/120
list 3 target organ damages as a result of HTN
- CKD
- LVH
- hypertensive retinopathy
1st line meds for pt with LHF and HTN
ramipril increased to 10mg
daniel,39 has a home bp reading of 138/82 what is the appropriate response from you, the gp?
- refer to cardiology
daniel is <40 and hypertensive so appropriate for referral
doris, 81 has T2DM, you have diagnosed her with hypertension, what is the appropriate medication to prescribe?
ACEi/ARB
- diabetes taken into account over age so ACEi more appropriate than CCB
what is the stepwise ladder for treating HTN in a pt under 55 not black or carribbean family origin or adult with T2DM (4)
- ACE-i or ARB
- CCB or thiazide-like diuretic
- ACE-i or ARB + CCB + thiazide-like diuretic
- = resistant hypertension, check K+ levels and then low-dose spironolactone +bb
what is the stepwise ladder for a treating HTN for a patient that is black African or African-caribbean family origin and/or >55?
- CCB
- ACE-i or ARB or thiazide-like diuretic
- ACEi or ARB + CCB + thiazide like diuretic
- resistant hypertension
how does an ACE-i work?
- interferes with RAAS= increased sodium urine secretion
- vasodilator (stops bradykinin breakdown)
common side effect of ramipril
cough
how do BB’s work?
work by blocking the effects of epinephrine (adrenaline) → slows heart rate and less force → lower BP
3 consequences of untreated HTN
- hypertensive retinopathy
- risk of cv event (HF/MI/LVH)
- stroke risk increase (QRISK3)
- vascular dementia
what class of drug is levetiracetam
anti-epileptic
A pt present with suspected Ovarian cancer, bloods are taken, what is the tumour marker for ovarian cancer?
Ca125
a patient presents with laryngitis, what symptoms need to be shown to make you wish to prescribe abx?(4)
- significant swelling
- white spots
- temperature
- struggle to swallow
what medication is used for breast cancer chemotherapy
aromatisei
- examestone - can affect bone density
- bisphospohonates can decrease bone mets
what is polymyalgia rheumatica and what is the associated condition it can lead to?
inflammation of the blood vessels -> temporal arteritis (giant cell arteritis) -> blindness
what is the common symptom of temporal arteritis
headache around the eyes
4 things we can use gabapentin for
- seizures
- menopause
- MS
- peripheral neuropathic pain
- MND
how can you assume an arthritis is RA?
RA is symmetrical
OA/psoriatic/gout are asymmetrical
what are the two components looked for in a semen analysis and what should the healthy percentage be?
speed (50%) and appearance (40%)
what are the first line medication for treating a UTI (2)
- nitrofuritoin and trimethoprim
need decent renal function -> penicillin/amoxicillin
list 3 signs/symptoms of parkinsons disease
- resting tremor “pin-rolling tremor”
- lack of facial expression
- shuffling gait (festinant gait)
what tests can you do for parkinsons on an examination
glabellar tap (tapping forehead, parkinsons wont stop blinking, not parkinsons eventually stop)
test tone = cogwheeling
what medications are used for parkinsons disease
dopamine agonists
levodopa (l-dopa)
what is frozen shoulder
limitation of external rotation
what is the treatment for frozen shoulder
local steroid injection - pred/lidocaine

nitrofuritoin for preventative
what is the action of anti-fibrinolytic drugs
prevent plasmin from breaking down fibrin

6m
what does a BMI of 31 show?
obese
what is the average eGFR for a 65 year old man?
85
what value for preserved ejection fraction suggests HF?
preserved ejection fraction <40
what are the two types of left sided HF?
- systolic failure with reduced ejection fraction
2. diastolic failure with preserved ejection
define right sided- heart failure
loss of RV ability to pump blood from heart to lungs, blood backs into veins = oedema
list 5 signs/symptoms of HF

- pulmonary crackles/oedema
list 3 risk factors for HF
- male

- previous MI
- heart valve disease
- HTN
- arrhythmia
- DM
- meds - nsaids
alcohol
obesity
etc
list 3 complications associated with heart failure?
- HF = less blood to the kidneys = kidney failure (dialysis)
- heart valve problems
- fluid build up in liver -> liver damage
what treatment may be considered for an ejection fraction <35% when treating HF?
consider implantable cardioverter defibrillator and cardiac resynchronisation therapy
when is pro-BNP released
response to pressure changes in the heart, higher in patients with HF
what stage of CKD is an GFR reading of 35 indicative of?
