Coronary artery perfusion is dependent upon: A. diastolic pressure B. systolic pressure C. afterload D. systemic vascular resistance (SVR) Correct Answers A. diastolic pressure Diastolic pressure in the aortic root is higher than left ventricular end-diastolic pressure (LVEDP), the pressure exerted on the ventricular muscle at the end of diastole when the ventricle is full. This enables blood to flow from a higher pressure through open arteries to a lower pressure, a pressure gradient known...

Calculate the cardiac output for a pt with a HR of 70 and a SV of 65 ct answerHR X SV=CO 70 X 65= 4550 4.6 L/min Calculate the cardiac output for a pt with a HR of 70 and a SV of 65 ml. HR X SV=COcorrect answerHR X SV=CO 70 X 65= 4550 4.6 L/min What % of the cardiac cycle is provided by the atrial kick? • 15% • 20% • 30% • 35%correct answer20%

The nurse observes that the patient's jugular veins distend in the semi-upright position to more than 5 cm above the sternal angle. This is an indication of: - correct answer -fluid volume overload. what is normal Pulmonary artery occlusion pressure (PAOP)? - correct answer -5-12 mmHg The resistance against which the left ventricle must pump to eject its volume is: - correct answer -systemic vascular resistance. When the tricuspid valve is open, central venous pressure reflects the fillin...

epoetin alfa - Correct Answer-anemia related to chronic kidney disease should be treated with ______________________. folic acid, Vitamin B12 - Correct Answer-Name two treatments for megaloblastic anemia. infection - Correct Answer-Glucose control (via insulin drip) in the post-CABG patient decreases the risk of ___________________.

Which of the ff do these changes most likely represent A. aspiration pneumonia B. pulmonary embolism C. interstitial pneumonitis D. ARDS (Answer) : D . The onset of symptoms occured within 48 hours of the incident. THe bilateral diffuse infiltrates and ABG results indicating hypoxemia and CO2 retention are all consistent with ARDS. Aspiration pneumonia should include hypoxxemia, respiratory alkalosis. The CXR results would reveal an area of opacity with aspiration pneumonia rather than di...

who is at risk for MDRO infection: patients with severe disease, including compromised host defenses from underlying medical conditions, recent surgery, or indwelling medical devices (ex: foleys or ET tubes) 2. what are classic signs of cardiac tamponade (Answer) hypotension, narrowing pulse pressure, tachycardia with weak, thready pulse, and tachypnea 3. what arrhythmia is mitral valve insufficiency associated with (Answer) afib 4. what defines oliguira (Answer) less than 500 ml of output ...

S1 - Correct Answer-Mitral and tricuspid "lub" of "lub dub" S2 - Correct Answer-Aortic and pulmonic "dub" of "lub dub" S3 - Correct Answer-Ventricular Gallup. Beginning of diastole after S2. Too much volume S4 - Correct Answer-Rare. Atrial Gallup. Resistance to filling. End of diastole

What is the function of the cardiovascular system correct answerto drive O2 to the cell so that the cell can make ATP for energy production What is the formula for CARDIAC OUTPUT correct answerStroke volume x Heart Rate CO = HR X SV ( Preload + Afterload + Contractility) What is the term for the amount of blood that is pumped out of the ventricle each MINUTE? correct answerCardiac Output ( approximately 4 - 8 LPM )

A nurse in the emergency department assesses a patient with a hand laceration and notices that the patient smells strongly of alcohol. The patient is diabetic, irritable, and pale and reports headache. The nurse is waiting for laboratory results. What serum glucose level might the nurse expect to find? a. 50 to 60 mg/dL b. <50 mg/dL c. >1000 mg/dL d. 80 to 110 mg/dL - Correct Answer-b. <50mg/dL

A patient with chronic renal failure asks the nurse why he is anemic. The nurse explains that anemia accompanies chronic renal failure secondary to: a. Blood loss via the urine b. Renal insensitivity to vitamin A c. Inadequate production of erythropoietin d. Inadequate retention of serum iron - Correct Answer-c. Inadequate production of erythropoietin
