AANPCB FNP Tests First-Line Primary Care Decisions — Not Specialist-Level Workups
For family nurse practitioner graduates sitting a 150-question lifespan exam weighted toward adults. Pick what a primary care NP does next: the right first test, current guideline screening and first-line therapy.
Check Your Readiness →Most candidates understand AANPCB Family Nurse Practitioner Certification Examination (FNP) concepts — and still fail. This exam tests how you apply knowledge under pressure.
AANPCB, now operating as the Nurse Practitioners Certification Board, also spreads scored items by age: young, middle and older adults take 105 of 135. Vignettes are short, so the clue is usually age, onset or one finding that changes urgency.
Diagnose Bell palsy and start outpatient treatment
Forehead sparing points to a central lesion such as stroke, because the upper face has bilateral cortical input. Bell palsy is peripheral and weakens the whole hemiface. Treat this as a possible stroke and arrange emergency evaluation.
Attribute it to progression of known dementia
Acute onset with fluctuating inattention means delirium until proven otherwise. Search for the cause, such as infection, medication effects, dehydration or urinary retention, remembering that older adults may have infection without fever.
Start metformin alone and add agents only if A1C stays high
Metformin and lifestyle change remain the base for most patients, but heart failure calls for adding an SGLT2 inhibitor for its proven benefit, chosen for the comorbidity rather than the A1C. ASCVD or CKD similarly drive agent choice.
Take the entire history with the parent present
Use HEEADSSS and spend part of the visit with the adolescent alone so they can disclose sexual activity, substance use, mood or safety concerns. Explain confidentiality and its limits to both the teen and the parent.
Average-risk colorectal screening now starts at 45 and biennial mammography runs from 40 through 74. Lung cancer screening is annual low-dose CT for ages 50 to 80 with 20 pack-years who smoke or quit within 15 years; chest radiographs are never a screening option.
TSH alone is the initial thyroid screen, with free T4 only after an abnormal result. Microcytic anaemia goes to ferritin first. Acute low back pain without red flags needs no early imaging. The most comprehensive workup is rarely the keyed primary care answer.
New headache after 50 with jaw claudication suggests giant cell arteritis; sudden scrotal pain with an absent cremasteric reflex suggests torsion; a painful red eye with halos suggests angle-closure glaucoma. Each needs urgent referral, not routine outpatient treatment.
Fluoroquinolones are not first-line for uncomplicated cystitis; nitrofurantoin or fosfomycin are. The Beers Criteria steer most older adults away from first-generation antihistamines and benzodiazepines. Trimethoprim-sulfamethoxazole, metronidazole and fluconazole can raise the INR in patients taking warfarin.
ACE inhibitors, ARBs, warfarin, isotretinoin and tetracyclines are avoided in pregnancy. Pelvic or abdominal pain in anyone who could be pregnant starts with a pregnancy test, because ectopic pregnancy must be excluded before other diagnoses.
