Answer to Question 1
Incidence is the number of new cases arising in a given population during a specified time. The correct incidence is three new patients had influenza during the month of January.
Tertiary prevention is directed at clinical interventions that prevent further deterioration or reduce the complications of a disease once it is diagnosed. Two examples for this patient are taking an antihypertensive medication and using an inhaler.
Pathophysiology is defined as the physiology of altered health. This patient has COPD and hypertension, which are examples of altered health.
Answer to Question 2
Physiologic jaundice refers to jaundice in the neonate unrelated to any pathologic process. It is a result of elevated levels of circulating unconjugated bilirubin in the body. The bilirubin is a product of the hemoglobin removed from worn-out red blood cells. Normally the liver is capable of conjugating the bilirubin so that it can be eliminated. When the liver is immature and incapable of metabolizing bilirubin, the unconjugated form remains in circulation and provides the infant with the characteristic yellowish pigmentation of the skin.
Infant colic is determined by the rule of three: an infant who is otherwise healthy demonstrates crying for more than 3 hours a day for more than 3 days a year and for greater than 3 weeks at a time. When intolerance is expressed toward breast milk and cow's milk, a lactase deficiency in the infant should be suspected.
Failure to thrive refers to inadequate growth in a child as a result of the inability to obtain or utilize dietary nutrients. Organic failure to thrive refers to a physiologic condition in the child that limits the uptake and utilization of nutrients. In nonorganic failure to thrive, the child's physiological processes are intact, but nutrition is unavailable. Nonorganic failure to thrive is therefore caused by psychological factors.
