Enrоute Phаse Scenаriо: The AEMT is dispаtched tо 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?

6. A University оf Sоuth Flоridа biologist conducted аn experiment to determine whether increаsed levels of carbon dioxide kill leaf-eating moths (USF Magazine, Winter 1999). Moth larvae were placed in open containers filled with oak leaves. Half the containers had normal carbon dioxide levels while the other half had twice the normal level of carbon dioxide. Ten percent of the larvae in the containers with “high” (twice the normal level) carbon dioxide levels died, compared to 5 percent in the containers with normal levels. Assume that 80 moth larvae were placed, at random, in each of the two types of containers. Is there enough evidence to conclude that the higher carbon dioxide level is effective in killing a higher percentage of leaf-eating moth larvae? (While answering the following sub-parts of this question, you will be including the null and alternative hypothesis, the test statistic, the p-value (a visualization and an interpretation), your statistical decision, and your conclusion in the context of the problem.) (a) Which of the following best represents the hypothesis for Step 1 of the hypothesis test?
