Enroute Phase Scenario:  The AEMT is dispatched to a community dental office for a 28-year-old female patient who is reportedly acting strangely and refusing to allow anyone near her. The call was received at 1440. The estimated response time is 9 minutes. The AEMT is partnered with an EMT, and a BLS fire department engine crew is also en route. Law enforcement has been requested but has not yet arrived on scene. It is overcast and 52°F (11°C) on a mild afternoon. Traffic in the area is moderate. The patient is located in a private dental suite within the office. The nearest hospital is 10 minutes from the scene.  OnScene Phase Scenario:  The patient (approximately 40 kilograms) is standing in the corner of a private dental suite, mumbling incoherently and clutching her chest. She appears visibly frightened and refuses to sit, make eye contact, or respond to verbal commands. The dental staff states that the patient was agitated upon arrival and repeatedly claimed that someone was “chasing her.” The patient has a history of anxiety and a prior psychiatric admission, and she takes sertraline for depression. She has no known drug allergies. There are no signs of trauma. The patient has not attempted to harm herself or others but is refusing to answer questions or follow instructions. Law enforcement has arrived and is standing outside the room. The patient’s level of consciousness appears intact, but her behavior is paranoid and disorganized. No vital signs have been obtained at this time.  Post Phase Scenario: The patient was safely restrained with the assistance of law enforcement and placed on the stretcher. She is now lying still but intermittently crying and speaking incoherently. She does not answer questions but no longer resists care. The patient’s skin is warm and dry, and there are no signs of trauma. She remains in soft restraints and is being transported to a facility equipped for psychiatric evaluation and stabilization. Eyes are open, and pupils are 4 mm and reactive to light. The vital signs are: blood pressure is 138/82 mmHg, pulse is 108 beats per minute, respirations are 18 per minute, SpO₂ is 98% on room air, and temperature is 98°F (37°C).  Why is it important to continue transport to a facility with psychiatric evaluation services, even if the patient appears calmer? 

Treatment for eating disorders such as anorexia nervosa and bulimia often involves a team or multi-disciplinary approach.  Which member of the health care team listed below would LEAST likely be involved in the direct treatment of this patient?

If a condition or disease is said to be idiopathic, what does this mean?

A PTA is working on the acute wing of a large hospital, and decides to take vitals because the patient has become pale and complains of weakness and dizziness. These signs and symptoms are most consistent with which disease/disorder?

What is the maximum acceptable blood pressure allowed for a general blood donor?

Extra Credit –  FUN MLS 413 related Extra Credit If the physician ordered 4 units of A positive blood on a patient that had an unexpected Anti-Fya and an unexpected Anti-Jka, how many donor units would need to be antigen typed to theoretically find 4 compatible donor units?  (Fya antigen is present in 65% of the donor population, while the Jka antigen is positive in 77%.) Round up any decimal to the next whole donor unit.

One unit of random donor platelets (RDPs) should increase the recipient’s platelet count by:

For Lana Kane, let’s imagine the antibody you selected has its corresponding antigen present at 45% in the donor population, how many donor units in the blood bank fridge will need to be antigen typed to find 3 units that are potentially antigen negative.  Round up any decimal to the next whole donor unit.

When disease testing the donor unit, what three tests do they run to screen for Hepatitis B specifically?

What would be the best choice for the positive control and negative control when performing antigen typing?
