NCLEX Review Adult Health ~ 52 Selected Lab & Diagnostic Tests Questions Nursing Considerations & Safety http://usnnursing.pbworks.com/ http://nursing--pharmacology.pbworks.com/ Questions and Answers 1. A client’s laboratory results reveal a hemoglobin of 6 g/dL. Which foods should be encouraged for this client? A. B. C. D. Broiled fish Whole grains Dried fruits Steamed vegetables 1. A client’s laboratory results reveal a hemoglobin of 6 g/dL. Which foods should be encouraged for this client? A. B. C. D. Broiled fish Whole grains Dried fruits Steamed vegetables C. With a low hemoglobin, the oxygen-carrying capacity of the blood is diminished resulting in client fatigue. The preserving agent for dried fruits adds iron, making the fruits excellent sources for this mineral. Normal Hgb range ~ 14-17 g/dl 2. Which nursing diagnosis is most appropriate for a female adult client with a hemoglobin of 12.0 mg/dL and a hematocrit of 29%? A. B. C. D. Fluid volume excess Decreased tissue perfusion Impaired tissue integrity Risk for activity intolerance 2. Which nursing diagnosis is most appropriate for a female adult client with a hemoglobin of 12.0 mg/dL and a hematocrit of 29%? A. B. C. D. Fluid volume excess Decreased tissue perfusion Impaired tissue integrity Risk for activity intolerance A. Hemoglobin is normal. Hematocrit should be 3 times the hemoglobin. If it is less than that, it indicates over hydration or hemodilution. Normal Hgb range ~ 14-17 g/dl Normal Hct ~ 36-50% (males higher than females) 3. The reticulocyte count is elevated in a client with recent blood loss due to severe skin laceration. In planning care, the RN anticipates which physician order? A. B. C. D.

Increased reticulocyte count is normal after blood loss or in anemia. It indicates the bone marrow is working to replace lost RBCs by producing immature RBCs and sending them into the circulation. 4. Which statement would be true of platelets? A. B. C. D. Are formed and stored in the spleen Repair damage to small blood vessels Cause red blood cells to clump forming clots Circulate for 4-6 weeks before dying 4. Which statement would be true of platelets? A. B. C. D.
