Air that enters the pleural space during inspiration but is unable

to exit during expiration creates a condition called:

-tension pneumothorax -open pneumothorax 1 / 4

• | P a g e

-pleural effusion -empyema - ANSWER-TENSION PNEUMOTHORAX

Air that enters the pleural space during inspiration but is unable to exit during expiration causes a tension pneumothorax. The question does not describe open pneumothorax, pleural effusion, or empyema.

Pernicious anemia is caused by a lack of:

-iron -intrinsic factor -folate -erythropoietin - ANSWER-INTRINSIC FACTOR

The fundamental defect causing pernicious anemia is the lack of intrinsic factor. Without it, vitamin B12 cannot be absorbed. Iron deficiency does not lead to pernicious anemia. Rather, it is the most common cause of anemia and is the result of unavailability of iron for hemoglobin synthesis. Pernicious anemia and folate deficiency are similar in etiology. Both are caused by a disruption in DNA synthesis of blast cells in bone marrow.Erythropoietin is necessary for the production of red cells. 2 / 4

All the following stress-induced hormones increase blood

glucose except:

-aldosterone -cortisol -norepinephrine -epinephrine - ANSWER-ALDOSTERONE

Aldosterone results in water and sodium retention and potassium loss in the urine. It does not affect blood glucose. Cortisol is a glucocorticoid secreted by the adrenal cortex. Cortisol stimulates gluconeogenesis in the liver, thus increasing blood glucose.Norepinephrine inhibits insulin secretion, thus increasing blood sugar. Epinephrine increases glucose release from the liver and inhibits insulin secretion, thus increasing blood glucose.

Patent ductus arteriosus is accurately described as a(n):

-opening between the atria -stricture of the aorta that impedes blood flow -communication between the aorta and the pulmonary artery 3 / 4

-cyanotic heart defect associated with right-to-left shunt - ANSWER-COMMUNICATION BETWEEN THE AORTA &

PULMONARY ARTERY

A patent ductus arteriosus is a normal channel between the pulmonary artery and the aorta that remains open during intrauterine life. A patent ductus arteriosus is not an opening or a stricture in the atria. Patent ductus arteriosus is an acyanotic congenital defect.

Persistence of the alarm stage will ultimately result in stress reduction.

permanent damage and death movement into the resistance stage exhaustion of the sympathetic nervous system - ANSWER- PERMANENT DAMAGE & DEATH

If the alarm stage were to persist, the body would soon suffer undue wear and tear and become subject to permanent damage and even death. Actions taken by the individual during the resistance stage lead to stress reduction. The resistance stage may or may not occur following the alarm stage, based on
