Matrix Multiple Response questions, commonly known as Select-All-That-Apply (SATA), are among the most challenging question types on the NCLEX. These questions require you to evaluate multiple options simultaneously and select all correct answers—testing your clinical judgment in complex, realistic scenarios.
What Are Matrix Questions?
Matrix questions present a clinical scenario followed by multiple response options. Unlike traditional multiple-choice questions where you select one best answer, Matrix questions require you to select ALL correct options. The number of correct answers varies—there could be 2, 3, 4, or even all options being correct.
The Next Generation NCLEX (NGN) uses Matrix questions to assess your ability to:
- Recognize multiple relevant cues in a clinical scenario
- Identify all appropriate nursing interventions
- Prioritize multiple actions in complex situations
- Apply clinical judgment across multiple decisions
Why Matrix Questions Matter
Matrix questions reflect the reality of nursing practice. In clinical settings, you rarely make single isolated decisions. Instead, you:
- Assess multiple findings simultaneously: A patient may have several abnormal vital signs, lab values, and symptoms requiring attention.
- Implement multiple interventions: Care often involves several nursing actions working together.
- Consider multiple hypotheses: Differential diagnoses require evaluating all possibilities.
- Coordinate multiple aspects of care: Patient care involves education, medication, monitoring, and follow-up.
Types of Matrix Questions
Traditional Select-All-That-Apply
A clinical scenario with a list of 4-6 options. You select all that apply. Example: "Which of the following are signs of hypoglycemia?" with options like tremors, diaphoresis, confusion, polyuria, and blurred vision.
Matrix Grid Questions
A table or grid where you select appropriate responses for each row or column. Example: Matching nursing interventions to different patient conditions, with multiple interventions potentially applying to each condition.
Matrix Multiple Choice
A combination where you select one option from each column in a matrix. This tests your ability to make multiple related decisions within a clinical context.
Clinical Examples
Clinical Example 1: Heart Failure Management
Scenario: A 68-year-old patient with heart failure is admitted with dyspnea, bilateral leg edema, and weight gain of 5 pounds in one week. The nurse is developing a care plan. Which of the following nursing interventions are appropriate? (Select all that apply)
- A. Administer furosemide (Lasix) as prescribed
- B. Encourage fluid intake of at least 3 liters per day
- C. Monitor daily weights at the same time each morning
- D. Position patient in high Fowler's position
- E. Assess lung sounds for crackles
- F. Encourage ambulation to promote circulation
Correct Answers: A, C, D, E
Clinical Rationale: Furosemide reduces fluid volume (A). Daily weights monitor fluid balance (C). High Fowler's position eases breathing (D). Lung assessment detects pulmonary edema (E). Fluid intake should be restricted, not encouraged (B is incorrect). Ambulation is inappropriate for a patient with acute heart failure exacerbation—rest is needed (F is incorrect).
Clinical Example 2: Diabetic Ketoacidosis (DKA)
Scenario: A 22-year-old patient with Type 1 diabetes is admitted with diabetic ketoacidosis. The nurse is monitoring for signs of improvement. Which findings indicate the patient's condition is improving? (Select all that apply)
- A. Blood glucose decreasing from 450 to 250 mg/dL
- B. Serum potassium level increasing from 3.2 to 4.0 mEq/L
- C. Arterial pH decreasing from 7.25 to 7.15
- D. Bicarbonate level increasing from 12 to 18 mEq/L
- E. Rate of ketone production decreasing
- F. Level of consciousness becoming more alert
Correct Answers: A, B, D, E, F
Clinical Rationale: Decreasing blood glucose shows treatment effectiveness (A). Potassium normalizing indicates proper replacement and safety (B). Increasing bicarbonate shows acidosis resolving (D). Decreasing ketones indicate metabolic correction (E). Improved consciousness indicates better cerebral perfusion (F). A decreasing pH would indicate worsening acidosis, not improvement (C is incorrect).
Clinical Example 3: Post-Operative Assessment
Scenario: A patient returns from abdominal surgery. Which assessment findings require immediate nurse intervention? (Select all that apply)
- A. Temperature of 99.8°F (37.7°C) 2 hours post-op
- B. Urine output of 25 mL in the last 2 hours
- C. Incisional pain rated 6/10
- D. Serosanguineous drainage on dressing 2cm in diameter
- E. Oxygen saturation of 88% on room air
- F. Restlessness and confusion
Correct Answers: B, E, F
Clinical Rationale: Low urine output may indicate fluid volume deficit or renal compromise requiring intervention (B). Oxygen saturation of 88% indicates hypoxemia requiring immediate intervention (E). Restlessness and confusion can indicate hypoxia, hemorrhage, or other complications requiring immediate assessment (F). Mild temperature elevation is common post-op (A). Moderate pain is expected (C). Small amount of serosanguineous drainage is normal (D).
Key Strategies for Matrix Questions
Use these proven strategies to approach Matrix questions systematically:
Treat Each Option Independently
Read each option as a separate true/false question. Don't let your decision on one option influence another. Ask: 'Is this statement true for this patient in this situation?'
Look for Absolute Words
Words like 'always,' 'never,' 'all,' 'none' often signal incorrect options. Nursing is rarely absolute—there are usually exceptions based on patient context.
Apply the Nursing Process
Use ADPIE (Assessment, Diagnosis, Planning, Implementation, Evaluation) to organize your thinking. Many Matrix questions test interventions or assessment findings.
Prioritize ABCs and Safety
When evaluating options, prioritize Airway, Breathing, Circulation, and safety. Options that address these are often correct. Eliminate options that could harm the patient.
Common Mistakes to Avoid
- Selecting all options: Don't assume all options are correct. Evaluate each one critically and only select those that clearly apply.
- Second-guessing correct answers: If you've analyzed an option and determined it's correct, don't deselect it because you've already selected "too many."
- Ignoring patient context: An intervention that's correct for one patient may be contraindicated for another based on their specific condition.
- Rushing through the question: Take time to read each option carefully. Missing a key word (like "not" or "except") can lead to incorrect selections.
- Not using elimination: If you're unsure, eliminate clearly incorrect options first. This increases your chances of partial credit.
How NGN Tests Matrix Questions
The Next Generation NCLEX uses Matrix questions to assess clinical judgment through the CJMM framework:
- Recognize Cues: Identify multiple relevant findings in a complex scenario.
- Analyze Cues: Determine which findings are clinically significant.
- Prioritize Hypotheses: Rank multiple potential problems by urgency.
- Generate Solutions: Identify all appropriate interventions.
- Take Action: Select nursing actions that should be implemented.
- Evaluate Outcomes: Determine which findings indicate improvement or deterioration.
Understanding Partial-Credit Scoring
NGN Matrix questions use partial-credit scoring, which differs from traditional all-or-nothing scoring:
- +/- Scoring: You earn points for correct selections and lose points for incorrect selections.
- Rational Scoring: Partial credit is awarded based on how many correct options you selected.
- No penalty for unanswered options: Not selecting an incorrect option is better than selecting it.
- Focus on confidence: Select only options you're reasonably sure about. Guessing can reduce your score.

FAQ: Matrix Questions
How many options should I select in a Matrix/SATA question?
There's no fixed rule—select ALL options that are correct. The NCLEX doesn't specify how many answers are correct. You might need to select 2, 3, 4, or even all options. Treat each option as a separate true/false question. Don't try to guess the number of correct answers; evaluate each option independently.
What is partial-credit scoring for Matrix questions?
NGN Matrix questions use partial-credit scoring called +/- scoring or rational scoring. You earn points for correct selections and lose points for incorrect selections. This means partial knowledge is rewarded—you don't need to get every option right to receive some credit. Focus on selecting only the options you're confident about.
How do I avoid selecting too many or too few options?
Read each option independently as a true/false question. Don't second-guess yourself based on how many you've already selected. If you've analyzed all options and only 2 are correct, select only 2. If 5 are correct, select all 5. Avoid patterns like 'there's always 3 correct answers'—this doesn't exist on NCLEX.
What's the most common mistake on Matrix questions?
The most common mistake is overthinking—either selecting too many options due to doubt, or selecting too few due to fear of being wrong. Also, students often miss 'negative' options that seem correct but include one wrong element. Always verify each option independently against the clinical scenario.
How does NGN test clinical judgment in Matrix questions?
NGN Matrix questions often present complex clinical scenarios requiring you to prioritize actions, recognize multiple assessment findings, or identify all appropriate interventions. Clinical judgment is tested by requiring you to synthesize information, apply the nursing process, and make multiple decisions simultaneously within one question.
