The parents of a five year old girl complain anxiously to her pediatrician that in the last couple of weeks, no matter how much she eats, she keeps losing weight. She appears quite thin, well below her normal weight. Her blood sugar is 300 (normal range 70-99). She is diagnosed with Type I diabetes mellitus (DM 1). This girl's body needs to compensate for the acid/base imbalance noted above. Knowing that the lungs will compensate when the "metabolic" side is "sick" and the kidneys will compensate when the lungs are "sick," which compensatory response would you expect? a. Hyperventilation --increased respiratory rate (RR)-- to "blow off" CO2; this is the lungs' way to get rid of acids. b. Hypoventilation—decreased RR-- to "hold onto" CO2, since CO2 is an alkali that will counteract the acidosis. c. Kidneys will excrete more HCO3 into the urine to get rid of acidic byproducts. d. By hyperventilating and blowing off CO2, the body will bring the pH down to normal range.

His breath smells fruity, like acetone. His pH is 7.14 and HCO3 18. Link aspects of his clinical presentation to the pathophysiology underlying them. a. Patient can't eat hypoglycemiainsulin secreted from pancreas triggers glycogenolysis as a back-up plan raises blood sugar but byproducts include ketones. b. Difficulty breathing increased metabolic needsuses up all energy sources body begins to use HCO3 as source of energyHCO3 depleted HCO3 decreases to 18, causing pH to increase from normal to 7.14. c. Chronic illnessincreased stressincrease in counterregulatory hormonesglycogenesis triggeredtoo much glucose being stored rather than being readily availablecachexia. d. Given the description of the patient's debilitated state, he is probably in sustained gluconeogenesisgives energy but also increases accumulation of ketones body tries to get rid of them via many ways, including as acetone in the breath.

A 55-year-old man with emphysema (a type of chronic lung disease) who has smoked 2 packs of cigarettes per day for 40 years is hospitalized for acute onset of cough productive of bloody sputum (sputum=secretions from deep in the lungs). After a few days of testing and treatment, the patient's nurse reads a physician's note on the chart: "I have told the patient that the etiologies of his hemoptysis are: 1) exacerbation of his chronic emphysema and 2) the new diagnosis of lung cancer. The onsets of both were contributed to by his longstanding smoking." Based on all the information you have on the patient, which statement is most likely correct? a. The patient has a poor prognosis because of the comorbidities of lung cancer and cigarette smoking. b. Lung cancer was a sequela of the bloody sputum. c. A precipitating factor for the acute hospitalization was overexertion when the patient started an exercise class. d. Heavy cigarette smoking was a risk factor in the patient's developing emphysema and lung cancer.

d. Heavy cigarette smoking was a risk factor in the patient's developing emphysema and lung cancer.

A 55 year old male is in the ER having a myocardial infarction (heart attack, AKA "M.I."), which is caused by coronary arteries that are clogged with fat and narrowed so that not enough oxygen-rich blood is getting to his heart. He admits that his daily nutrition is poor, consisting mainly of high-fat fast food. He has a family history of cardiac disease-- his father had a heart attack at age 46. The patient is obese and is a heavy cigarette smoker-- 2 PPD (packs per day). The patient said he had decided to take up jogging today and after a few minutes began having chest pain, nausea and shortness of breath. He went to the ER and was noted to have profuse diaphoresis (heavy sweating), tachycardia (rapid heart rate), and significant changes on his electrocardiogram (ECG or EKG). The patient recovers from this acute heart attack but his heart is so damaged that subsequently he has many episodes of congestive heart failure and many hospitalizations. Without even having further knowledge of course material related to MI's, you can tell a lot about the scenario from careful reading and knowledge of basic patho verbiage. Example: The paragraph above suggests that the direct pathophysiologic etiology of the heart attack (MI) is most likely related to a. not eating green vegetables. b. congestive heart failure. c. lack of oxygen that narrows the coronary arteries. d. oxygen not reaching tissue that is distal to narrowing of the coronary arteries.

d. oxygen not reaching tissue that is distal to narrowing of the coronary arteries.

The parents of a five year old girl complain anxiously to her pediatrician that in the last couple of weeks, no matter how much she eats, she keeps losing weight. She appears quite thin, well below her normal weight. Her blood sugar is 300 (normal range 70-99). She is diagnosed with Type I diabetes mellitus (DM 1). In this scenario, the explanation that bests links pathophysiology with S&S in this child is that in DM1, the pancreas a. quits producing glucagon so that glycogen stores are inaccessible, thus causing weight loss. b. increases insulin production so that glucose stays in the blood, causing hyperglycemia. c. quits producing insulin so that glycogenolysis is stimulated and too much glucose enters the blood. d. quits producing insulin so that glucose cannot be used as energy in the cells, thus causing the body to burn up fat and protein for energy.

d. quits producing insulin so that glucose cannot be used as energy in the cells, thus causing the body to burn up fat and protein for energy.

A young, otherwise healthy patient is admitted to the hospital with a diagnosis of heart failure of unknown cause. The etiology of the heart failure would be termed a. iatrogenic. b. idiopathic. c. nosocomial. d. acute.

b. idiopathic.
