Exam 16: Pulmonary Anatomy and Physiology

Which statement describes the relationship between the pulmonary circulation and the pulmonary vascular bed?

Based on the oxyhemoglobin dissociation curve,respiratory acidosis will have which effect?

Which physiologic alteration will stimulate the central chemoreceptors?

Which factor will result in a shift of the oxyhemoglobin dissociation curve to the left?

Patients who have aspiration pneumonitis often present with right lower lobe involvement more than left lower lobe involvement.Why does this occur?

How much of the basal oxygen consumption is required by the pulmonary system during normal quiet breathing?

What are the primary functions of the pulmonary system?

Which pulmonary alteration increases the work of breathing in the patient with emphysema?

Oxygen saturation of left atrial blood is normally between 96% and 99%.What is the explanation for less than 100% saturation?

What is the movement of air into and out of the lungs termed?

Which part of the pulmonary anatomy does most of the work of breathing?

Trauma to which vertebrae will cause ventilation dysfunction?

Which factor will increase diffusion of gases across the alveolar capillary membrane?

Which artery(s)have the lowest oxygen saturation?

Which nerve stimulates movement of the diaphragm?

Which statement about methemoglobin is true?

A patient in diabetic ketoacidosis would exhibit what alteration to the pulmonary system?

What substance do Alveolar type II cells secrete?

Which physiologic mechanism is a passive event in a spontaneously breathing patient?

A patient is admitted with community-associated pneumonia.Respirations are 32 breaths/min.Temperature is 102° F (38.6° C).Based on the readings the nurse would expect the oxyhemoglobin dissociation curve to shift.What other factors would cause the curve to shift in the same direction?
