Answer to Question 1

ANS: B
A. Incorrect response: The transairway pressure is the pressure difference (gradient) between the alveolar pressure and the mouth pressure (atmospheric pressure). This pressure gradient is responsible for the flow of air into and out of the lungs during spontaneous breathing and mechanical ventilation.
B. Correct response: An esophageal balloon measures pressure in the midesophagus, which reflects pressure in the pleural space.
C. Incorrect response: During mechanical ventilation, alveolar distending pressure can be estimated by conducting an inspiratory pause. The plateau or static pressure reflects the pressure responsible for maintaining the lungs in an inflated state.
D. Incorrect response: Pressures in the distal endotracheal tube are considered tracheal pressures.

Answer to Question 2

ANS: C
A. Incorrect response: Alveolar distending pressure is the pressure required to maintain the lungs inflated at the end of inspiration. The pressures Pstatic and Pplateau are essentially interchangeable.
B. Incorrect response: The static pressure is the pressure obtained during an inspiratory pause. It is the pressure exerted to main lung inflation at the end of inspiration.
C. Correct response: Airway pressure or airway opening pressure measures the pressure inside the ventilator or within the ventilator tubing.
D. Incorrect response: The transpulmonary pressure is the pressure difference (gradient) between the alveolar pressure and the pleural pressure. It is the pressure responsible for enabling the lungs to fill during inspiration.

The use of salicylates dates back 2,500 years to Hippocrates's recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.

Though newer “smart” infusion pumps are increasingly becoming more sophisticated, they cannot prevent all programming and administration errors. Health care professionals that use smart infusion pumps must still practice the rights of medication administration and have other professionals double-check all high-risk infusions.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
