Prioritization &
First Action

Master the art of deciding who to see first and what to do next using proven nursing frameworks.

NCLEX-RN

Why Prioritization Matters

On the NCLEX-RN, many questions ask who do you see first? or what is your first action? These test your clinical judgment under pressure: identifying the patient or task that, if delayed, could cause the most harm.

Key Terms

Prioritize
Rank patients or tasks in order of urgency, addressing life-threatening needs first.
First Action
The single most important step the nurse takes immediately for a given patient.
Acute vs Chronic
New, unstable (acute) problems outrank long-standing, stable (chronic) ones.

The ABC Framework

A Airway Is it open and clear? Highest priority. B Breathing Is the patient ventilating adequately? C Circulation Pulse, blood pressure, perfusion, bleeding. priority order

Maslow's Hierarchy

Self-actual. Safety & Love Physiological air, food, fluid, elimination address base first

The Core Rule

Think of priority as a ratio of urgency to time. If we let \( U \) represent urgency, the patient with the highest \( U \) is seen first:

$$ \text{Priority} = \max(U_1, U_2, \dots, U_n) $$

Stable vs Unstable

Stable / Expected
Vital signs within range, symptoms expected for the diagnosis, chronic and unchanging. Lower priority.
Unstable / Unexpected
New, sudden, worsening, or abnormal findings (drop in oxygen, chest pain, confusion). See FIRST.

How to Apply It

1
Scan each patient for life-threatening problems using ABC.
2
Identify unstable findings. Anything new, sudden, or unexpected.
3
Apply Maslow. Physiological needs before psychosocial.
4
Choose the least invasive, most data-gathering first action (assess before intervening).

Assess Before You Act

Assess Decide Act

Example 1: Who First?

Four patients call for the nurse at once. Using ABC, who gets seen first?

A
A patient with new-onset shortness of breath and oxygen saturation dropping. ← FIRST (Breathing)
B
A patient requesting pain medication for a chronic ache.
C
A patient who wants to discuss discharge plans.
D
A patient asking for an extra blanket.

Example 2: First Action

A post-op patient reports sudden chest pain and feels short of breath. What is the nurse's first action?

Correct First Action
Apply oxygen and raise the head of the bed to improve oxygenation, then assess vitals.
Not First
Calling the provider or documenting comes after stabilizing breathing.

Example 3: Expected?

Which finding requires immediate attention?

1
A diabetic patient with a blood glucose of 130 mg/dL.
2
A post-op patient with mild incisional pain.
3
A patient who is suddenly confused and restless. ← ACT

Common Mistakes

✕ Choosing the loudest patient
A complaining patient is not always the sickest. Quiet, deteriorating patients are often higher priority.
✕ Acting before assessing
Jumping to call the doctor or give a drug before gathering data, when assessment should come first.
✕ Ignoring ABC order
Treating circulation problems before securing the airway. Always go A, then B, then C.

Question 1 of 5

The nurse has four patients. Using the ABC framework, which should be seen first?

Question 2 of 5

A patient suddenly reports chest pain and shortness of breath. What is the nurse's first action?

Question 3 of 5

Which finding is unexpected and needs immediate attention?

Question 4 of 5

Per Maslow's hierarchy, which patient need is addressed first?

Question 5 of 5

A patient's IV alarm sounds and they appear restless. What should the nurse do first?

You're Ready

Remember: ABC, then Maslow, see the unstable patient first, and assess before you act.
