MFSEM Written common mistakes
MFSEM Written · Understand the traps and how to avoid them.
Calculates a target heart-rate range with 220 minus age and prescribes it unchanged for a patient on a beta-blocker or with an implanted device.
The age-predicted formula is overlearned and easy to apply; candidates forget that chronotropic drugs and conduction disease make the estimate invalid.
What to do instead
Use an individualised anchor (measured HRmax or field test) plus RPE/talk test, and explicitly state that beta-blockade blunts HR so intensity should be prescribed by perceived exertion or workload.
Writes that fat oxidation peaks at maximal exercise intensity and designs a weight-management plan around high-intensity work only.
Candidates conflate total energy expenditure with substrate utilisation and recall 'high intensity burns more calories' without the fat-oxidation curve.
What to do instead
State that absolute fat oxidation peaks at moderate intensity (roughly 45-65% VO2max) and total fat loss depends on energy deficit; combine moderate continuous work with higher-intensity intervals and diet.
Labels anterior knee pain in a 13-year-old as patellofemoral pain after a knee exam only, without examining the hip or asking about a limp.
Pattern recognition for common knee conditions is strong, and the hip is psychologically 'a different joint'; candidates forget referred pain and slipped capital femoral epiphysis.
What to do instead
In every paediatric knee presentation, examine hip rotation and gait, and use age-appropriate red-flag questions (limp, night pain, systemic symptoms) before giving a mechanical diagnosis.
Treats atraumatic shoulder pain as rotator cuff tendinopathy without screening for night pain, fever, weight loss, cancer history or cervical referral.
The common musculoskeletal diagnosis anchors the consultation, and candidates fear over-investigating; red-flag lists are recalled for back pain but not shoulder.
What to do instead
Apply a standard red-flag screen to all atraumatic joint pain, examine the cervical spine, and arrange urgent imaging/referral if systemic features or progressive night pain are present.
Reads T-wave inversion in leads V1-V3 in a Black athlete as definite hypertrophic cardiomyopathy without applying ethnicity-specific ECG criteria or arranging echo.
Candidates memorise 'TWI = HCM' but not the normal Black athlete pattern and the need for corroborating features.
What to do instead
Apply the current athlete ECG interpretation criteria, distinguish benign repolarisation patterns, and confirm with echo/cardiac MRI and family history before disqualifying.
Diagnoses exercise-induced bronchoconstriction from cough and wheeze during exercise and starts an inhaler without bronchoprovocation or reversibility testing.
Symptoms overlap with breathing pattern disorder, vocal cord dysfunction and poor fitness; candidates accept a therapeutic trial as diagnostic.
What to do instead
Confirm with objective testing (eucapnic voluntary hyperpnoea, methacholine, exercise challenge, or mannitol) and consider paradoxical vocal fold motion before prescribing.
Normalises secondary amenorrhoea in a lean female endurance athlete as 'training effect' and does not assess energy availability or bone health.
Menstrual dysfunction is still treated as a normal consequence of hard training; relative energy deficiency in sport is under-recognised outside specialist clinics.
What to do instead
Treat amenorrhoea as a red flag: calculate energy availability, screen for low bone density and stress fracture risk, and involve dietetics and gynaecology.
Permits same-day return to play after a suspected concussion because the athlete's symptoms resolved and SCAT6 was normal on the sideline.
Candidates equate symptom resolution with recovery and forget that same-day return to play is not permitted in most sports.
What to do instead
Remove from play, document SCAT6, and follow a graduated return-to-learn then return-to-sport protocol with at least 24 hours per step; same-day return is not allowed.
Prescribes oral prednisolone for an athlete's asthma exacerbation and an intramuscular glucocorticoid for a joint injury without checking TUE requirements.
Candidates check the prohibited list for anabolic agents but assume common anti-inflammatory drugs are always permitted.
What to do instead
Consult the current WADA Prohibited List/Global DRO for every prescribed medicine; oral, intramuscular and some other glucocorticoid routes are prohibited in competition and require a TUE.
At an on-field collapse, spends the first minutes manually immobilising the cervical spine before checking responsiveness, airway and applying an AED.
Spinal-injury protocols are over-applied from trauma teaching, and candidates fear causing cord injury.
What to do instead
Follow the emergency action plan: check responsiveness/breathing, call for AED and start CPR immediately if unresponsive and not breathing normally; immobilise the spine only after life threats are addressed.
