Nine Cases of Vomiting and Diarrhea in Unit C on a Friday Night
At 2140 on a Friday, the evening nurse at a 240-bed county jail learns that nine of the 48 men in Housing Unit C have had watery diarrhea and vomiting in the past 36 hours. Two are clinically dehydrated; one has a blood pressure of 88/54 and has vomited four times. The unit shares two toilets and one shower. The facility has one negative-pressure cell, four empty single cells, and no single cells in the adjacent dorm. The resident who serves Unit C trays in the kitchen lives in Unit C. Six men from Unit C are scheduled for court at 0800 Saturday; the transport deputy says the judge will not accept cancellations. There is no on-site physician until Monday, but the medical director is reachable by phone.
1. It is 2140 Friday. What are your first three actions, and how do you decide which of the six men go to court at 0800?

Treat this as an outbreak, not nine sick calls. Nine cases in 48 residents in 36 hours is roughly a 19% attack rate in a unit with shared toilets and one shower - a pattern consistent with person-to-person or point-source enteric spread. Because a Unit C resident handles the tray line, foodborne illness has to stay on the differential until it is excluded.
Action 1 - separate and cohort. Move the symptomatic men into the four single cells and use the negative-pressure room for the most symptomatic; cohort the remainder geographically. The goal is to stop shared toilet and shower use, not to achieve true isolation, which is impossible here. Say so explicitly in your note rather than charting an isolation that does not exist.
Action 2 - break the chains you can break. Soap-and-water handwashing (alcohol rub is unreliable against norovirus), dedicated toileting for the ill cohort if portable equipment exists, gloves and gown for direct contact, scheduled bleach-based disinfection of the shower and toilets, and removal of the kitchen worker from food handling until 48–72 hours after symptoms resolve. Notify the medical director, infection control, and food service tonight.
Action 3 - start a line list with a case definition, onset times, symptoms, vitals, hydration status, and treatments. It organizes care and doubles as your documentation.
Court: custody, not nursing, decides whether an appearance is legally compelled. Your job is to state medical fitness in writing for each man. Anyone actively vomiting or diarrheic is not fit to travel and is a contamination hazard on a transport van. Put that recommendation in writing and by phone to the transport deputy and the court, notify your medical director, and document who you told, when, and who decided what. Do not clear a symptomatic man because the schedule is inconvenient, and do not refuse on security grounds you do not own.
2. Two men are dehydrated, one hypotensive and vomiting repeatedly. What can you do on site tonight, and what makes you send him out?

Assess for severity first, not for a diagnosis. Mental status, orthostatic vitals, mucous membranes, skin turgor, urine output, ability to keep fluid down, abdominal exam, and a symptom screen for blood or high fever. Note comorbidities - cardiac disease, renal disease, diabetes on metformin - because they lower your threshold for transfer.
What you can do on site: serial vitals, a graded oral rehydration trial (small frequent volumes, e.g., 5–10 mL every few minutes) if he is alert and not vomiting persistently, and IV crystalloid if your scope, standing orders, and equipment permit it. Call the on-call provider for orders rather than working from memory. Antiemetics per protocol to enable oral intake. Recheck and record vitals after each intervention.
Transfer triggers - any one is enough: hypotension that does not respond to a fluid challenge, altered mental status, persistent inability to tolerate oral intake, hematemesis or bloody diarrhea, severe or localized abdominal pain with guarding, high fever with toxicity, or a comorbidity that makes outpatient-level care unsafe. Do not delay transfer to complete a workup you cannot complete in the facility.
Reasoning to hold onto: in an outbreak, the decision is not 'is this probably viral?' - it is 'can this patient be safely managed with the resources physically present tonight?' If the answer is no, the transfer is justified regardless of the eventual diagnosis. Document the serial findings that drove the decision.
3. What goes in the medical record, what goes to custody, and what stays out of both?
Read the worked answer
In the medical record: the case definition and line list, each patient's objective findings and vitals over time, hydration status, interventions and times, provider calls and orders, isolation/cohorting measures actually implemented, education given, and a clear statement of what could not be done (for example, 'no single cells available; cohorting implemented'). Also record the clinical fitness recommendation for each of the six court cases and the name of the person who received it.
To custody: operational information they need to run the unit safely - which men are in which cells, which need door-open access or monitoring, that the kitchen worker is off food handling, that symptomatic men should not be transported, and what to do if a resident collapses or cannot be roused. Give them the fitness determinations in writing. Keep it behavioral and operational.
Out of the security log and out of unit chatter: specific diagnoses, test results, and any unnecessary clinical detail. The custody staff need to act, not to know. If an officer needs a specific fact to keep someone safe (for example, a seizure risk), give that one fact to that one person.
Why this matters: a nurse who over-shares creates a confidentiality problem in a setting where inmates already have little privacy; a nurse who under-shares creates a clinical safety problem. The dividing line is whether the information changes what the officer must do.
