Explain ejection fraction and list normal and abnormal values.
Ans) The ejection fraction (EF) refers to the amount, or percentage, of blood that is pumped (or ejected) out of the ventricles with each contraction. This percentage, or EF number, helps your health care provider determine how your heart is functioning.
- A normal left ventricular ejection fraction (LVEF) ranges from 55% to 70%. An LVEF of 65%, for example means that 65% of total amount of blood in the left ventricle is pumped out with each heartbeat.
- Heart failure with reduced ejection fraction happens when the muscle of the left ventricle is not pumping as well as normal. The ejection fraction is 40% or less. The amount of blood being pumped out of the heart is less than the body needs.
Differentiate between two normal and two abnormal findings on a neurologic exam. Explain what the abnormal findings may indicate and the patient education that would be required when explaining the abnormal findings.
What are the normal/abnormal lab values for HDL? If HDL is too low, what are the recommendations?
Explain the results of the following cross in Drosophila: abnormal wing x abnormal wing The progeny: 53 - normal wing; 97 - abnormal wing. Explain the mode of inheritance and ratios of the progeny (use the chi-square test, if necessary). Write down the scheme of the cross and genotypes of the parents and offspring.
10. Significance of abnormal values of hemoglobin. What are the normal values (=reference range) for your analyte? What could a high value indicate? (i.e. suggestive of diabetes, kidney failure, etc.) What could a low value indicate? analyte is hemoglobin.
What are the normal/abnormal lab values for Triglycerides? What is the diet therapy for high triglyceride levels?
Distinguish between abnormal and normal results with the results below and explain each scenario. 1. A 6 year old has a hematocrit of 36%. Is that normal? 2. A 54 year old patient has a WBC count of 13000/mm3. Is it high or low? 3. A 23 year old has a hematocrit of 32% and hemoglobin of 10 g/dl. Are these values high or low? What might this patient’s diagnosis be? 4. Another patient has a platelet count of 142,000/mm3....
Explain how the abnormal cell division of cancerous cells escapes normal cell cycle controls.
Explain the five personality dimensions specified in the DSM-5 on which both normal and abnormal variation in personality can be described.
Use the random decimal fraction generator at Random.org, linked here, to generate a list of three fractions with four decimal places. Assume those decimal fractions represent probability values associated with z-scores. Then use the standard normal table to look up the z-score that is closest to matching with that probability. List them below. (3 points) probability value (generated fraction) = associated z-score = probability value (generated fraction) = associated z-score = probability value (generated fraction) = associated z-score = The...
