Today’s question focuses on early recognition of patient deterioration and the nurse’s first priority action. This skill matters because many NCLEX questions test whether you can spot the most dangerous cue, connect it to the underlying problem, and respond in the safest order. In real nursing, that can prevent a patient from crashing while the team is still figuring out what is wrong.
Clinical Scenario
A 68-year-old man is admitted to a medical-surgical unit with community-acquired pneumonia. He has a history of type 2 diabetes, hypertension, and chronic kidney disease stage 3. He has been receiving IV antibiotics and 2 L/min oxygen by nasal cannula. At 0700, the night nurse reports that he was tired but alert and oriented.
At 0830, the day nurse finds him more restless and confused. He is trying to remove his oxygen tubing. His vital signs are: temperature 38.9 C (102 F), heart rate 118/min, respiratory rate 30/min, blood pressure 86/54 mm Hg, and oxygen saturation 90% on 2 L/min nasal cannula. His skin is warm, and capillary refill is delayed. Urine output over the last 4 hours is 60 mL.
The Question
Which action should the nurse take first?
Answer Choices
- A. Increase the oxygen to 4 L/min by nasal cannula and reassess in 30 minutes
- B. Notify the provider that the patient may need a different antibiotic
- C. Activate the rapid response team and begin applying high-flow oxygen per facility protocol
- D. Obtain a full set of orthostatic blood pressures to confirm hypotension
Correct Answer
C. Activate the rapid response team and begin applying high-flow oxygen per facility protocol
Detailed Rationale
This patient is showing signs of sepsis with possible septic shock. The key clues are fever, tachycardia, tachypnea, hypotension, confusion, low urine output, and worsening oxygenation. The nurse’s first job is not to explain the cause in detail. The first job is to recognize that the patient is unstable and act fast.
The most urgent threats are poor oxygen delivery and poor tissue perfusion. His blood pressure is low, his mental status has changed, and his urine output is decreased. Those findings suggest organs may not be getting enough blood flow. His respiratory rate is also high, which often means the body is trying to compensate for infection, hypoxia, or metabolic acidosis.
The best first action is to activate the rapid response team because this patient needs immediate escalation. He may need aggressive fluid resuscitation, broader oxygen support, labs such as lactate and blood cultures, and possibly vasopressors if hypotension does not improve. A bedside nurse should not delay that response while doing less urgent tasks.
Applying higher oxygen per protocol is also appropriate because his oxygen saturation is falling and his work of breathing is increased. Oxygen does not treat sepsis itself, but it helps support tissue oxygenation while the team addresses the underlying problem.
After calling rapid response and initiating oxygen, the nurse should continue focused assessment and support. That includes:
- Reassessing airway, breathing, circulation, and mental status
- Checking lung sounds and work of breathing
- Placing the patient on continuous pulse oximetry and cardiac monitoring if available
- Ensuring IV access is patent, and preparing for possible fluid bolus
- Reviewing urine output trends, because low output is an early sign of organ hypoperfusion
- Getting sepsis-related labs and cultures if ordered or included in protocol
- Monitoring response to interventions every few minutes, not every hour
The reason this answer is strongest is simple: the patient is unstable now. Safe nursing care means escalating quickly before the patient deteriorates further.
Why the Other Options Are Wrong
A. Increase the oxygen to 4 L/min by nasal cannula and reassess in 30 minutes
This does part of what the patient needs, but it is not enough. Oxygen support is appropriate, but waiting 30 minutes to reassess is unsafe in a hypotensive, confused patient with likely sepsis. He needs immediate escalation, not delayed observation.
B. Notify the provider that the patient may need a different antibiotic
The patient may eventually need a change in treatment, but this is not the first priority. The nurse should first respond to the signs of acute instability. Sepsis management depends on rapid support of oxygenation and perfusion. A routine provider message is too slow for this situation.
D. Obtain a full set of orthostatic blood pressures to confirm hypotension
This is unnecessary and potentially harmful. The patient is already hypotensive. Orthostatic measurements require position changes, which could worsen his condition and delay urgent care. The nurse already has enough evidence that the patient is unstable.
Key Takeaways
- New confusion in an infected patient is a major red flag. It often signals worsening perfusion or hypoxia.
- Fever, tachycardia, tachypnea, hypotension, and low urine output together should make you think about sepsis.
- On the NCLEX, the first priority is often the action that addresses immediate instability and gets help fast.
- Do not delay emergency escalation for extra confirmation data when the patient already shows clear danger signs.
What you’d do on shift:
- Recognize the pattern of sepsis early
- Call rapid response or follow the unit’s escalation protocol
- Support oxygenation right away
- Keep IV access ready and monitor vital signs closely
- Track urine output, mental status, and response to treatment
Quick Practice Extension
1. A patient with a urinary tract infection becomes confused and has a lactate of 3.8 mmol/L after a fluid bolus. Which reassessment finding would worry you most?
2. A patient with suspected sepsis has an oxygen saturation of 95% but a blood pressure of 82/48 mm Hg and urine output of 15 mL in 2 hours. What should the nurse prioritize next?
