NURS660 Hematology Exam Questions Complete Solutions Current Update (A+ Pass) A patient is experiencing shortness of breath, pallor, and dizziness. Do you suspect an acute or chronic anemia? - Acute blood loss Chronic is often asymptomatic until very severe What does an MCV value tell you? What is a normal value? What would a low and high value be called? - the size of the RBC normal: 80-100 >100: macrocytic (large RBC) <80: microcyctic (small RBC) What does an MCHC value tell you? What is a normal value? What would a low and high value be called? - the "color" of the RBC or how saturated it is with HGB 2 | P a g e Author: Katelyn Whitman. ©2025, All Rights Reserved. Normal: 32-37 high value not a thing <32: hypochromic (lacking HGB) What does an RDW value tell you? What is a normal value? What would a low and high value be called? - essentially how far apart the RBCs are from each other - the further apart, the less RBCs, otherwise they would be closer just based on the sheer volume ranges about 11-15% but for testing purposes I think it will just say elevated or low Describe in what types of infections/scenarios the types of WBCs would be elevated. Neutrophil Lymphocyte Eosinophils Monocytes Basophils - Neutrophil: first line for bacterial infection Lymphocyte: first line for viral infection Eosinophils: allergies, parasitic infections Monocytes: share function with neutrophils, only elevated in SEVERE infections 3 | P a g e Author: Katelyn Whitman. ©2025, All Rights Reserved. Basophils: parasitic, allergic, inflammation If your CBC comes back abnormal, what is something you can do next? - add on a peripheral smear if you didn't get one already Anisocytosis on your peripheral smear is/is not concerning - not concerning normal size variant Blasts on your peripheral smear is/is not concerning - Very concerning blasts = red flag for leukemia, requires an oncology referral blasts should remain in bone marrow until mature and ready to be released Smudge cells on peripheral smear are seen with - CLL What are the two smear cells you may see on a patient with IDA? - ovalcyte/elliptocyte OR teardrop cells Target cells and basophilic stippling on smears are indicative of... - thalassemia Spherocytes on smear may indicate - hemolytic anemia What is the most common trigger for the bone marrow to produce more RBCs? - decrease in o2 Name the normal lab values for these labs RBC 4 | P a g e Author: Katelyn Whitman. ©2025, All Rights Reserved. Hemoglobin Hematocrit - RBC: 4.1-5.8 Hgb: 12-16 in women 14-17.5 in men Hct: should be roughly 3x hgb 33-45% in women 38-51% in men What hemoglobin value requires an immediate ED referral? - <7 In a macrocytic, normochromic anemia, you would expect what labs? - Decreased RBC/Hgb/HCT (Hgb most commonly used) Increased MCV (>100) Normal MCHC (32-37) Name some causes for macrocytic normochromic anemia. - B12 deficiency Folate deficiency Alcohol induced Liver disease Multiple myeloma 5 | P a g e Author: Katelyn Whitman. ©2025, All Rights Reserved. In a normochromic, normocytic anemia, you would expect what labs? - Decreased RBC/Hgb/HCT (Hgb most commonly used) Normal MCV (80-100) Normal MCHC (32-37) RDW often normal as well not an abnormal cell, just less of them Causes of normochromic, normocytic anemia - Anemia of chronic disease Acute blood loss/bleeding
