Overview

Domain 3 has four official tasks. Establishing a patient-centered, evidence-based plan of care means applying current guidelines while respecting the patient's goals, culture and resources. Initiating interprofessional referrals or consultations means knowing when a problem exceeds primary care or needs urgent specialty input. Prescribing, ordering or administering treatments covers first-line drug choices, contraindications, interactions and non-drug therapies. Providing education, counseling and health promotion covers immunizations, lifestyle change, anticipatory guidance and safety teaching.

At 26.5% of scored items, about 36 questions, Plan is tied with Diagnose. Most items ask for the best initial treatment or the most important teaching point, and safety drives many answers: avoiding teratogens in pregnancy, avoiding potentially inappropriate drugs in older adults, and choosing narrow-spectrum antibiotics. The exam tests drug selection and safety far more than exact dosing.

How it's tested

Plan items state a diagnosis, or make it obvious, and ask for the best initial therapy, the most appropriate referral, the drug to avoid, or the priority teaching point. The right answer follows current national guidelines and puts patient safety first, especially for pregnant patients, children and older adults.

  • First-line therapy

    A diagnosis is given and you choose the guideline-recommended initial drug or non-drug treatment.

  • Safety and contraindications

    A patient factor such as pregnancy, age, renal function or an interacting drug makes one option unsafe, and you avoid it.

  • Priority teaching or referral

    You choose the most important education point, counseling approach or referral for the situation.

Reasoning it through

A 26-year-old nonpregnant woman has dysuria and frequency without fever or flank pain. Ciprofloxacin works, which makes it tempting, but fluoroquinolones carry serious adverse effect warnings and should be reserved for situations where other options are unsuitable. Guidelines list nitrofurantoin, trimethoprim-sulfamethoxazole where local resistance is low, or fosfomycin as first-line therapy for uncomplicated cystitis, so a first-line narrow agent is preferred.

Tasks 4

Official tasks from the AANPCB outline, in outline order.

3.1 Establish a patient-centered, evidence-based plan of careApplying current guidelines while reflecting patient goals, culture and resources.
What it means
This task covers combining guideline-based management with the patient's preferences, health literacy, cost concerns, culture and social drivers of health. It includes shared decision making, setting realistic goals, and choosing management appropriate to age and comorbidities, such as individualized A1C targets for frail older adults.
What to understand
Evidence-based means following current national guidelines, such as ADA Standards of Care, ACC/AHA hypertension and cholesterol guidance, GINA for asthma, GOLD for COPD and CDC immunization schedules. Patient-centered means the plan fits the person: a frail older adult may need less aggressive glucose targets, and a patient who cannot afford a drug needs an alternative that still meets the evidence. Lifestyle measures are part of nearly every chronic disease plan.
How it shows up
A diagnosis and patient context are given and you choose the plan that is both guideline-concordant and appropriate for that individual.
Common confusion
Picking the most intensive regimen when the patient's age, frailty or goals call for a modified target.
3.2 Initiate interprofessional referrals or consultationsKnowing when and to whom to refer, and how urgently.
What it means
This task covers recognizing when a condition exceeds primary care scope or needs specialist input, choosing the right discipline, and deciding urgency. Examples include emergency department transfer for suspected acute coronary syndrome, same-day ophthalmology for angle-closure glaucoma, dermatology for a suspicious pigmented lesion, and physical therapy, social work, dietitian or behavioral health referrals.
What to understand
Referral questions test both necessity and urgency. Emergencies, such as suspected stroke, torsion or ectopic pregnancy, need immediate transfer rather than an outpatient appointment. Many chronic problems, such as uncomplicated hypertension or type 2 diabetes, stay in primary care, and referring them can be the wrong answer. Interprofessional referrals, such as physical therapy for low back pain or a dietitian for new diabetes, are part of good care. Consultation keeps the NP managing the patient, while referral transfers part of care.
How it shows up
A situation is described and you choose whether to refer, to whom, and how urgently, or decide that primary care management is appropriate.
Common confusion
Referring stable chronic conditions that are within the family NP's scope of practice.
3.3 Prescribe, order or administer pharmacologic and non-pharmacologic treatmentsFirst-line drugs, contraindications, interactions and non-drug therapy.
What it means
This task covers choosing first-line medications, avoiding contraindicated drugs, recognizing interactions and major adverse effects, and using non-drug and integrative therapies. Examples include metformin for most type 2 diabetes, penicillin or amoxicillin for strep pharyngitis, avoiding ACE inhibitors in pregnancy, and applying the Beers Criteria for older adults.
What to understand
Know drug classes, first-line choices and the safety issues that eliminate options. ACE inhibitors and ARBs are contraindicated in pregnancy, and ACE inhibitors can cause cough and angioedema. Fluoroquinolones carry tendon rupture and other warnings. Trimethoprim-sulfamethoxazole and metronidazole raise the INR in patients on warfarin. The Beers Criteria advise avoiding first-generation antihistamines and benzodiazepines in most older adults. For asthma, GINA no longer recommends SABA-only treatment for adults and adolescents. Non-drug options such as exercise, weight loss and physical therapy are often first-line.
How it shows up
A diagnosis and patient factors are given and you choose the safest first-line treatment or identify the drug to avoid.
Common confusion
Choosing an effective drug that is contraindicated by pregnancy, age, renal function or an interacting medication.
3.4 Provide education, counseling, and health promotion strategiesImmunizations, lifestyle counseling, anticipatory guidance and medication teaching.
What it means
This task covers teaching patients and families about their condition and medicines, counseling for behavior change such as tobacco cessation, delivering anticipatory guidance and safety teaching for children, and promoting immunizations and preventive care. It includes communication methods such as motivational interviewing and teach-back, and cultural responsiveness.
What to understand
Priority teaching is the point that prevents the most harm, such as recognizing angioedema on an ACE inhibitor or placing infants on their back to sleep. Motivational interviewing explores ambivalence rather than lecturing, and teach-back confirms understanding. Know the CDC schedules for routine vaccines, including Tdap in every pregnancy and HPV vaccination starting at 9 to 12 years. Tobacco cessation counseling combined with pharmacotherapy works better than either alone.
How it shows up
A teaching or counseling situation is described and you choose the priority message or the most effective communication approach.
Common confusion
Choosing a true teaching point that is less important for safety than the correct answer.

Answer framework

Use these steps for any Domain 3 treatment, referral or teaching item.

  1. Confirm the diagnosis and its severity, and check whether the situation is an emergency that needs immediate transfer rather than outpatient treatment.
  2. Identify patient factors that limit choices, such as pregnancy, age, renal or hepatic function, allergies, current medications and cost or access barriers.
  3. Choose the guideline-recommended first-line therapy, including non-drug measures, and eliminate any option contraindicated by those factors, even if it is effective.
  4. Decide whether primary care management, consultation or referral fits, matching urgency to the clinical risk and to the limits of primary care scope.
  5. For education items, choose the teaching point that prevents the most harm and confirm understanding with teach-back or support change with motivational interviewing.

Study strategy

Plan rewards knowing first-line choices and the reasons to avoid alternatives. Start by building a table of the 30 or so conditions you see most in primary care, such as hypertension, type 2 diabetes, hyperlipidemia, asthma, COPD, depression, anxiety, urinary infection, pharyngitis, otitis media, sinusitis, community-acquired pneumonia, gout, osteoarthritis and common skin infections. For each, list the first-line treatment, a key alternative, and one safety issue.

Next, learn safety by population. Make short lists of drugs to avoid in pregnancy, in older adults using the Beers Criteria, and in children. Add the high-yield interactions, especially those involving warfarin, and the signature adverse effects of common classes.

Then study referral and education. Practice deciding whether a scenario needs emergency transfer, outpatient referral, consultation or primary care management. Review the CDC immunization schedules and the main anticipatory guidance topics by age. Use current guideline sources, since several recommendations have changed in recent years, including asthma relievers and diabetes drug selection. When practicing, explain why each wrong option is wrong, because Plan distractors are often effective drugs that are unsafe for the specific patient.
