Exam Flashcards
A pt with an acute exacerbation of COPD has the following ABG analysis: pH 7.32, PaO2 58 mmHg, paCO2 55 mmHg and sats 86%. You recognize these values as evidence of:
A. Respiratory acidosis
B. Respiratory alkalosis
C. Normal acid base balance with hypoxaemia
D. Normal acid base balance with hypercapnia
A. Respiratory acidosis
Following assessment of a pt with pneumonia, you identify a nursing diagnosis of ineffective airway clearance. You base this nursing diagnosis on the findings of:
A. SpO2 of 85%
B. Resp rate of 28 bpm
C. Presence of greenish sputum

A. Kidney
B. Lung
C. Cardiac
D. Alveolar
C. Cardiac
A pt has a chest tube following a thoracotomy. Regular intermittent bubbling in the suction chamber of the collection device would alert you that:
A. An air leak may b present
B. The lung has fully expanded
C. The unit is functioning normally
D. A tension pneumothorax is developing
C. The unit is functioning normally
A female pt is scheduled for a thoracentesis to obtain pleural fluid. She asks you to explain what causes the fluid in her lung; you explain that:
A. The pleural effusion could be caused by a tumor or other growth
B. A pleural effeson is not a disease but rather a sign of some other disease
C. Pleural effusions occur when there is any inflammation or infection in the lung
D. The cause of pleural effusions is not known but they can be treated by removing the fluid with a needle or tube
B. A pleural effusion is not a disease but rather a sign of some other disease
Factors that influence the development of hypertension include all of the following except:
A. Increased sympathetic nervous system activity
B. Increased renal absorption of sodium chloride and water
C. Decreased activity or the renin-angiotensin system
D. Decreased vasodilation
C. Decreased activity of the renin-angiotensin system
You teach a pt with hypertension that uncontrolled hypertension may damage organs in the body primarily by:
A. Promoting atherosclerosis and damage of the walls of the arteries
B. Thickening capillary membranes, leading to hypoxia of organ systems
C. Causing direct pressure on organs, resulting in necrosis and replacement of cells with scar tissue
D. Increasing the viscosity of the blood, contributing to intravascular coagulation and necrosis of tissue distal to occlusions
A. Promoting atherosclerosis and damage of the walls of the arteries
In analyzing a pt’s ECG rhythm strip, you use the knowledge that the time of the conduction of an impulse from the SA node to the AV node is represented by the:
A. P wave
B. PR interval
C. QT interval
D. QRS complex
B. PR interval
Cardiac output is calculated by multiplying:
A. The stroke volume and after load
B. The stroke volume and the pulse rate
C. The stroke volume and impulse rate
D. The after load and the preload
B. The stroke volume and the pulse rate
One unit of packed cells is prescribed to be infused over 2hr. The volume of the packed cells 250ml. The infusion set drop factor is 20 d/ml. Which answer below is correct (to the nearest whole number).
A. 42 d/min
B. 84 d/min
C. 21 d/min
D. 125 d/min
A. 42 drops/min
A pt with acute coronary syndrome is admitted to ED. Which of the following statements is not true of this diagnosis:
A. His ECG demonstrates ST segment elevation with T wave inversion
B. His chest pain lasts only 2-5 mins
C. His chest pain occurs at rest
D. His cardiac markers are normal
B. Hs chest pain lasts only 2-5mins
CK-MB and troponin levels are evaluated for a pt who has experienced chest pain and aching for the last 4days. You expect:
A. Myoglobin levels will be needed to confirm myocardial damage
B. CK-MB will be the most reliable indicator of any myocardial necrosis that is present
C. Any serum cardiac marker will be inconclusive in determining myocardial injury that is several days old
D. The presence of myocardial damage occurring several days earlier can be validated best by troponin level
D. The presence of myocardial damage occurring several days earlier can be validated best by the troponin levels
Metabolic syndrome increases the risk of coronary artery disease and consists of insulin resistance and:
A. Smoking/hypertension/obesity
B. Smoking/dysipidaemia/genetics
C. Obesity/smoking/genetics
D. Obesity/dyslipidaemia/hypertension
D. Obesity / dyslipidaemia / hypertension
On admitting a pt with bladder Ca you identify a significant risk factor for this diagnosis is:
A. Chronic cystitis
B. Cigarettes smoking
C. High caffeine intake
D. Use if artificial sweeteners
A. Chronic cystitis
Following rectal surgery, the pt tells you that he urinates about 10ml of urine every 30-60mins. From the skit below the best action for you to take initially is to:
A. Palpate for a distended bladder
B. Have the pt drink only small amounts of fluid throughout the day
C. Show the pt how to apply pressure on his bladder during urination
D. Monitor the pt’s fluid intake and output over an 8hr period to determine whether urine output is adequate
