This is a multiple patient scenario involving 3 patients in the Observation Unit following a MVC. (1) R/O fetal distress/injury; (2) R/O Head Injury; (3) Splenic Laceration.
Patient A is a 35 y.o. mother, 19 weeks pregnant that was driving herself and her pre-school son to a clinic appointment when she was in a collision. She has a sprained wrist but otherwise appears to be stable. There is currently no evidence of vaginal bleeding. She is under observation prior to being cleared for discharge. Maternal/fetal assessment to R/O fetal distress/injury.
Patient B is Patient A’s 3 y.o. son. He was restrained in a child car seat and shows a mild abrasion to his forehead from the impact during the collision. He is stable and is under observation prior to being cleared for discharge. R/O head injury.
Patient C is 42 year old man. He was a restrained driver that was struck by another vehicle. The other vehicle struck the driver’s side door with about 2 feet of intrusion into the passenger compartment. He had a brief loss of consciousness but is now alert and conversant. He complains of left shoulder and chest pain and left upper quadrant abdominal pain. He is under observation, awaiting results from XRay and CT.
In this scenario learners are to prioritize and organize care in order to manage the various needs of the patients. They must accurately assess all 3 patients and recognize the signs of hypovolemic shock in Patient C in order to intervene effectively.

Learning Objectives:

Do What

With What

For What

Students will perform

focused assessments

to determine current patient status.

Students will accurately interpret

assessment findings, patient history and lab results

to organize and prioritize the care of multiple patients.

Students will respond to changes in patient status

by communicating with the interprofessional team

in order to intervene effectively.

Students will be able to coordinate the care of the three patients

with other care providers

to ensure the safe and timely delivery of care.

Students will apply knowledge and skills

acquired from previous laboratories, theory and clinical

in order to manage the care of a pediatric, a pregnant and a trauma client.

Simulation Modality:

Manikin-based, Standardized/simulated patients or real patients


2 mannikins and 1 SP are needed
