A night shift with no senior to ask
On a night shift with no senior nearby, use a cited reference for questions that can wait a few minutes, and escalate straight away for anything that cannot. For the first kind, ask one specific question, read the direct answer and open the source behind the step you plan to take, so the decision rests on a guideline or a reference rather than on a half-remembered teaching session. AskMed, an AI medical reference for doctors, nurses, pharmacists, medical students and researchers, answers from journals, guidelines and drug labels and links every claim to its source, on a phone or on the ward computer. It is not for emergencies: a deteriorating patient needs your senior, the outreach or rapid response team, or your local emergency process, not an app.

The situation: 3 a.m. and the question is yours
A night shift concentrates questions onto fewer people. A junior doctor covering several wards, or a nurse in charge of a busy bay, gets calls about results, new symptoms and drug charts, and the senior who would normally answer is in theatre, in the emergency department or at home on call. Many of these questions are not emergencies but still matter: an unexpected potassium, a sodium that has drifted down, new confusion in an older patient, an INR above the target range with no bleeding, or a drug that may not suit a patient's kidneys. The answer usually exists in a guideline or a standard reference, but finding the right page on a shared ward computer, while the bleep keeps going, takes time. The temptation is to act on memory or to defer everything to the morning. Typical questions sound like these:
- What ECG changes matter in hyperkalaemia, and which ones change how urgently it is treated?
- Which causes of new confusion in an older inpatient should be excluded first, and with which tests?
- What are the safe limits for correcting chronic hyponatraemia, and why do they matter?
What goes wrong without a cited source at night
Without a cited source, night-time decisions rest on memory, on whoever is nearest, or on a generic web search, and each fails in a predictable way. Memory is weakest when you are tired, and it holds old thresholds as confidently as current ones. A colleague on another ward may know less than you think. A web search returns patient pages and commercial sites, and a general chatbot can answer fluently without saying where the answer came from or which country's practice it follows. The result is either over-caution, where every question becomes a call to the on-call senior, or under-caution, where a plan is made on a rule that changed years ago. Handover then carries a decision nobody can trace to a source, and the day team has to check it again. A cited answer gives the decision a reference the next person can open.
- Fatigue errors. Recall of numbers and criteria is least reliable late in a shift.
- Untraceable plans. "Someone said" is hard to defend at handover or in the notes.
- Misplaced reassurance. A confident answer is not the same as a checked one.
How AskMed helps on a night shift
AskMed gives a tired clinician a cited answer to a specific question in seconds and makes the source one tap away. AskMed searches a fixed list of medical sources before writing: guidelines and agencies such as NICE, WHO and CDC; journals such as NEJM, The Lancet, JAMA and The BMJ; FDA and DailyMed drug labels; and references such as StatPearls, the MSD Manual and BMJ Best Practice. It does not search forums or social media. The answer starts with a direct reply and then adds only the sections the question needs, such as causes, criteria or what to rule out, each claim linked to its source. Lab values keep their numbers and are given in both unit systems where countries differ. When you say you are a clinician, AskMed answers peer to peer. For acute, unsafe situations, it is instructed to recommend urgent professional care.
Try asking
Inpatient with sodium 126 mmol/L, no symptoms, on a thiazide diuretic: what should be checked first, and what is the safe limit for the rate of correction?
The answer covers the first investigations, the correction limits and the risk of osmotic demyelination, with each claim linked. It gives no doses of any treatment.
- Device settings are not doses. Tube and airway sizes, ventilator settings and chest drain suction pressures are given with their numbers when the sources state them.
- Follow-ups keep context. "And if she becomes drowsy?" is read together with the previous answer.
- Private Mode. New questions are not saved to History when it is on.
- AskMed works on iPhone and iPad, Android and the web, with one account on all of them.
Checklist for a night-shift question
The checklist below separates what to escalate from what to check, then makes the check quick and traceable. It starts with escalation on purpose, because no reference, however well cited, replaces a senior review for a patient who is deteriorating, and early warning scores and local escalation policies exist for exactly that moment. For everything else, the steps take a couple of minutes on a phone or a ward computer: one specific question, a direct answer, one opened citation and a note of the source for handover. The steps use features that exist in AskMed on iPhone, iPad, Android and the web. They work for junior doctors, nurses, physician associates and pharmacists alike, and the same answer can be reopened from History by the person who asked it. Never type patient names or hospital numbers into any app question.
- Decide if it is urgent. If the patient is unwell or deteriorating, follow your escalation policy and call your senior or the rapid response team now.
- Write one specific question. Include age, the key result with its units, kidney function and relevant drugs, but no patient identifiers.
- Read the direct answer and the can't-miss causes. For a differential, AskMed lists the can't-miss causes first, then the common ones.
- Open the source behind your plan. Confirm the threshold or criterion in the guideline or reference itself.
- Take doses from the drug chart, label or formulary. AskMed explains options and how dosing is chosen, never amounts.
- Record the source at handover. Name the guideline or reference you checked, so the day team can follow your reasoning.
Limits on a night shift
AskMed has firm limits on a night shift, and they are the reason escalation comes first. AskMed is not for emergencies: in an emergency, call your senior, the rapid response team or your local emergency number. It is a reference for education and reference by healthcare professionals and students, not a substitute for clinical judgment, supervision or your hospital's protocols. It is not a symptom checker and it does not diagnose patients or decide treatment for a person. Answers are written by an AI language model, with no human review before you see them, so open the source behind anything you act on. AskMed never gives drug doses, infusion rates or schedules, and local policies on electrolyte replacement, sedation or anticoagulation can differ from national guidance. AskMed searches a fixed list of sources, so your trust's own guidelines will not appear in its answers.
Frequently asked questions
Can AskMed replace calling my senior?
No. For a patient who is unwell or deteriorating, call your senior or the rapid response team. AskMed is for questions that can wait a few minutes and for checking the source behind a plan.
Is AskMed useful for nurses on nights?
Yes. AskMed is built for nurses, doctors, pharmacists, students and researchers alike. Nurses use it for questions about results, conditions, drugs and monitoring, with every claim linked to its source.
Does AskMed give infusion rates or doses?
No. AskMed never gives doses, infusion rates or schedules, even for hypothetical cases. It explains the options and how dosing is chosen; amounts come from the label, the drug chart or your formulary.
Will my hospital's protocol appear in the answer?
No. AskMed searches a fixed list of national and international sources, not hospital intranets. Follow your local protocol where it differs.
Should I type patient details into AskMed?
Give only the clinical details the question needs, such as age, results and kidney function, never names or hospital numbers. Private Mode stops new questions being saved to History.
