Unformatted text preview: Mr. Fischbach has a 12 lead EKG performed and among other findings, the PR interval is found to be 0.16 seconds. This means: a. his ventricular activity is somewhat prolonged and could cause a decreased cardiac output. b. his electrical transmission of impulses from the ventricles thru the bundle branches is not occuring normally. c. his cardiac reserve is normal and would not likely be the cause of his cardiovascular symptoms. d. his electrical impulses are traveling from the atria thru the ventricle in the normal time period for a heart muscle. correct answer: d (know your cardiac electrophysiology...normal interval times, etc.) 2. A patient who has been diagnosed with TB of the bone tells the nurse that he thought TB was a lung disease. The nurse explains to the patient that: a. the tubercular organism is amild bacteria that spreads only in people who do not have a good immune system. b. the microorganism that causes TB starts in the lungs but usually spreads from the lungs to other parts of the body. c. the tuberculosis organism makes a cheesy-like cyst that breaks open and spreads the infection throughout the body. d. the lungs are the most common site of TB infection but the microoorganism can be spread to other organs through the blood and lymph systems. correct answer: d (the only possible two are b & d...but the wording "usually" in b makes d a better choice) 3. A patient is admitted to the hospital with a sudden onset of severe right upper quadrant pain that radiates to the right shoulder. She has a history of fat intolerance and heartburn. The nurse recognizes that the patient most likely has a bilary tract obstruction when the patient reports experiencing: a. spider angiomas b. clay colored stools c. dilute, bright colored urine d. epigastric pain relieved by vomiting correct ansewr: b (not tricky here...understand signs/symptoms of biliary tract obstruction) 4. Mr. Lehne has cirrhosis and develops portal hypertension. Which of the following reveals the pathophysiology of this condition? a. it is caused by less cardiac output being delivered to the liver from heart disease. b. it is caused by distention of the gastric organs and the biliary tract c. it is caused by compression & destruction of the hepatic & portal veins d. it is caused by increased ultrafiltration of the renal system correct answer: c (simply understand what causes portal hypertension...again, not tricky here) Mary, a 22 year old college student with a complaint of severe headaches and fever, was admitted with a diagnosis of meningococal meningitis. Several weeks later during a home visit Mary expresses her frustrations about not returning to school because of her difficulty walking. Which of the following nursing diagnoses would be most appropriate for Mary? 1. Altered tissue perfusion: cerebral related to decreased metabolism 2. Impaired walking related to pain 3. Altered comfort related to inflammation of cerebral tissue 4. Powerlessness related to residual effects of disease...
