Returning clinic phone messages: which caller the nurse rings back first
Written and reviewed by Dana Whitfield, RN, MSN · 4 min read · Updated October 2026
Short answer
When returning clinic voicemails, the nurse calls back the message suggesting a life-threatening problem first, such as chest pain, and directs that caller to emergency services. Next comes the high-risk caller, such as a young infant with fever, then new but stable symptoms like a rash, and finally routine requests such as prescription refills.
Chest pain goes first, and the answer is emergency services
Phone triage applies the same ABC logic as bedside care, with one difference: the nurse cannot see the caller, so the threshold for sending them to emergency care is lower. The CDC lists chest discomfort, pain spreading to the arm, jaw or back, shortness of breath and cold sweats as heart attack warning signs, and advises calling emergency services immediately.
The correct advice for that caller is to hang up and call emergency services now, not to come to the clinic or wait for an appointment. If the caller cannot be reached, follow the clinic's escalation process rather than moving on silently. Document the time of the message, the call back and the advice given.
A febrile young infant is the next priority
Fever means something different in a baby of a few weeks than in an older child. The Merck Manual explains that young infants with fever can be early in a serious bacterial infection such as meningitis, and that lethargy, poor feeding, breathing difficulty or a non-blanching rash call for hospital evaluation. NHS advice treats any fever of 38°C or higher in a baby under three months as needing urgent assessment.
Return this call immediately after the chest pain caller. Most protocols send a febrile infant this young for prompt emergency evaluation rather than a routine appointment. If the parent describes a baby who is floppy, difficult to wake, breathing with effort or has a rash that does not fade under pressure, the advice changes to emergency services. Ask about feeding and wet nappies to judge hydration.
Rashes and refills
A new rash in an adult who is otherwise well is usually a stable concern that can be returned after the urgent calls. Screen for red flags as soon as you speak: facial or tongue swelling, difficulty breathing or swallowing, fever with a rash that does not fade, or blistering or peeling skin. Any of these turns the call into an emergency.
Prescription refill requests are routine and come last, unless the caller has already run out of an essential medicine such as insulin or an anticonvulsant, which makes the request more time-sensitive. Acute problems are prioritised over chronic, stable ones, and the nurse can often delegate gathering refill details to clerical staff.
Phone triage safeguards
Because the nurse cannot see the client, structured questions and the clinic's triage protocols carry more weight. Ask open questions about the main symptom, when it started, whether it is getting worse and what the caller can see. Confirm the caller's identity and a callback number at the start, in case the line drops.
Close every call with clear advice about what to do and when to call back or seek emergency care. Document the time the message was left, the time it was returned, the information gathered and the advice given. A list of unreturned messages should be reviewed by the nurse, not left for clerical staff to sort by arrival time.
Worked example and distractors
In a hypothetical morning, four voicemails are waiting: a 60-year-old with chest pressure for an hour, the parent of a five-week-old with a temperature of 38.2°C, an adult with an itchy rash after starting an antibiotic, and a client requesting a blood pressure refill with three days left. The order is chest pain, infant fever, rash, then refill.
Calling back the rash first because an allergy sounds dangerous ignores that this caller reported no breathing problems, while the chest pain caller is time-critical. Calling the refill first because it is quick wastes the minutes that matter. Telephone triage advice is a registered nurse responsibility and should not be delegated to unlicensed staff.

Common questions
Should the chest pain caller be told to come to the clinic?
No. The caller should be advised to call emergency services immediately, because treatment for a possible heart attack is time-critical and a clinic visit delays it.
Why is fever in a young infant urgent?
Babies under about three months can have serious infections with few signs. Any fever of 38°C or higher in this age group needs urgent assessment, and red flags need emergency care.
When does a refill request become urgent?
When the client has run out of a medicine where a missed dose is dangerous, such as insulin or an anticonvulsant. Otherwise refills are handled after acute concerns.
