Though in the case of this test, the answer might be the tongue, in reality this is not the case. A study was conducted in 1985 by Dr M.P.Boidin to determine the causes of upper airway obstructions in unconcious patients. "In the cadaveric preparations it was obseved thatthe tongue did not usually reach to the posteriorpharyngeal wall, because it was attached mainly tothe posterior aspect of the mandible at the chin.When the tongue of the cadaver was pushed forciblyinto the mouth, obstruction occurred mainly at thelevel of t he soft palate—by closure of the natural oralairway. When more pressure was exerted, thenatural nasal airway was occluded also, the softpalate being pushed against the posterior pharyngealwall. In the lower pharynx, two mechanisms ofobstruction occurred—which were independent ofmanipulation of the tongue. The base of t he epiglot-tis closed over the trachea and the rims of t he epi-glottis came into contact with the posteriorpharyngeal wall and could close the respiratorytract. The visible part of t he epiglottis, the pars glot-tica, could extend into the oesophagus and so protectthe interarytenoid fold from contamination withforeign material."Boidin, M. (1985). Airway Patency In The Unconscious Patient.British Journal of Anaesthesia,57(3), 306-310. doi:10.1093/bja/57.3.306 In essence, it is not the tongue(at least not alone) that causes airway obstructions in unconncious patients, but rather the epiglottis.

The anwer is 0.25mlIf you have 2mg in 1ml, you are ordered to give 0.5 mg, and you give 1mg then you would give 0.5 mls. Half of that would be 0.5mg would be 0.25ml.

I got 4 hours and 10 mins.20gtts=2ml (because of 10 drop set) v2ml=1min v500ml/2ml(per 1 min)= 250ml v250ml - 60mins=190ml v190ml - 60mins=130ml v130ml - 60mins=70ml v70ml - 60mins=10ml v10ml - 5mins=0ml vThe answer should be 4 hours and 5 mins

This is incorrect. The DERMIS is the layer that houses the hair folcile and glands etc. The epidermis is the outer layer of the skin which is basically just comprised of the stratum corneum and the pigment layer.

My answer is abnormally low. According to ADA guidelines, normal random glucose test levels in an average adult range from 79-160 mg/dLor 4.4-7.8 mmol/L. A blood glucose level of 12 mg/dL is definitely not the high end of normal, it is dangerously low.

This answer is incorrect! the left atrium receives blood from the pulmonary veins. the left VENTRICLE pumps blood to the body!

Isn't the answer occlusion and hemorrhage? These are the two major events that cause cerebrovascular accidents or strokes.

Ventricular Fibrillation The spelling on the original answer is incorrect, therefore marking the answer wrong since the spelling is not matched.

The correct answer to this question is B, a 57 year old male with chest pain and systolic BP of 80. Chest pains can be caused by a number of issues including a heart attack, panic attack, or cancer.Along with chest pain, the patient could have a number of other symptoms, including pain in the neck, shoulder, back, and jaw. Over 5% of emergency room visits are complaints of chest pains, but only 2% of these patients are sent home, which is why they have priority. Blood pressure is the strength used to push blood against moving arteries. When blood pressure is high, it can damage the heart, kidneys, and blood vessels. This damage can lead to a heart attack or stroke.
