## Question

Stage 6 — Evaluate outcomes. Review the clinical and public-health trend and answer both questions.

| Time | Data |
| --- | --- |
| Arrival | BP 86/48; confused; capillary refill 4 seconds; lactate 4.1 mmol/L; urine output not established |
| 2 hours | BP 102/62 after resuscitation; follows commands; capillary refill 2 seconds; urine output 35 mL/hour |
| 6 hours | BP 110/68; oriented; lactate 2.2 mmol/L; urine output 45 mL/hour |
| 24 hours | Culture confirms N. meningitidis; roommate and partner identified; public health notified |

Q1. Which interpretation is best supported by the clinical trend?

Perfusion is improving, but continued surveillance and treatment are required
The falling lactate proves all organ risk has ended
The client is worsening because antibiotics were given
Blood pressure alone shows that meningitis has resolved

Q2. Which prevention plan is most appropriate?

Give prophylaxis to everyone in the college
Withhold prophylaxis from vaccinated close contacts
Ensure prompt prophylaxis for qualifying close contacts regardless of vaccination status and review indicated vaccination
Wait more than 2 weeks before evaluating contacts

## Explanation

Improving pressure, mentation, urine output, capillary refill, and lactate show improved perfusion. Close contacts with direct secretion or household-type exposure need prompt prophylaxis regardless of vaccination status; casual contacts do not automatically qualify.

## In-depth explanation

Quick answer
The client is improving, and prevention now depends on prompt, targeted prophylaxis for qualifying close contacts plus vaccination review.

Why this is correct
Better mentation, perfusion, urine output, blood pressure, and lactate support response, but treatment and monitoring continue. Roommates and people with direct oral or respiratory-secretion exposure are the priority contacts for prophylaxis.

Easy analogy or mental picture
Close the case in two circles: the inner circle confirms the client is recovering, and the outer circle finds the people whom respiratory secretions actually reached.

Memory hook
Trend the patient; trace the secretions.

NCLEX decision rule
When meningococcal disease is confirmed, evaluate both physiologic recovery and exposure control; prophylaxis is targeted to close contacts and is not cancelled by prior vaccination.

Why the other choices are wrong
One improved value cannot end surveillance. Mass prophylaxis is not routine, vaccination does not replace prophylaxis after qualifying exposure, and delay reduces preventive value.

## Clinical scenario

Case update
Ceftriaxone and sepsis resuscitation were started promptly. Blood culture confirms Neisseria meningitidis, and public health is coordinating exposure management.
