Laboratory medicine consists of five disciplines. Which discipline analyzes blood, urine, and other bodily fluids for electrolytes and proteins?

A physician orders 45% O2 through an air-entrainment nebulizer to a patient with a tidal volume of 0.6 Liters and a respiratory rate of 24 breaths/min. The maximum nebulizer input flow (flow meter setting) is 15 L/min. What is the air to 02 ratio? What is the total flow? What is the patient’s peak inspiratory flow? Does this device meet the patients’ needs?

Which mask system provided relatively high FI02 using adjustable air entrainment ports that controlled the amount of air mixed with 02?

Identify this device. What is the Fi02 range? Is the FI02 stability variable or fixed? What should the flowmeter be set on for this device?  

A venturi mask is the use of a 02 mask with controlled FI02 by means of air entrainment.

What is the air: oxygen ratio for 75% O2?

A patient wearing a low flow oxygen system with a fast rate of breathing will have an increase in FI02.

What is the abnormal platelet functioning called?

List two abnormities of thoracic configuration.

During the embryonic stage, Species X, Species Y, and Species Z all exhibit the presence of a structure called the ‘pharyngeal arch.’ In the adult stage, Species X retains the pharyngeal arch as functioning gills, while Species Y and Species Z lose this structure. Why is the presence of the pharyngeal arch in the embryonic stage of all three species considered an example of developmental homology?
