NURS 221 Nurse logic Knowledge and clinical judgment beginner 1. A nurse is precepting a newly licensed nurse while he is charting. Use of which of the following abbreviations indicates a need for further teaching? a. mcg b. q.d. c. mL d. PO Answer is B-q.d. is the incorrect term. To indicate daily, you should use the word "daily" when charting. Q.d. used to be confused for qid, which means 4x a day. 2. A nurse is caring for a client who is diagnosed with anemia. Which of the following skin color variations is caused by a reduced amount of oxyhemoglobin? a. Cyanosis b. Jaundice c. Erythema d. Pallor Answer is D-Pallor -Oxyhemoglobin is the combined state of oxygen that is to be delivered to peripheral tissues with the hemoglobin molecule that will carry it. In clients who have anemia, the RBCs are reduced, by function or in number, to the point that peripheral tissues are not receiving adequate oxygen because of a decreased amount of circulating oxyhemoglobin. The reduced oxygen supply to the tissues causes changes to the client's skin color. Pallor is caused by a reduced amount of oxyhemoglobin. Pallor is a decrease in the coloring of the peripheral tissues that is caused by an overall reduction in the blood flow or by a decrease in the number of RBCs that contain oxyhemoglobin, which reduces the visibility of oxyhemoglobin. Pallor Paleness of the skin - Decrease in the coloring of the peripheral tissues. Is caused by an overall reduction in the blood flow or by a decrease in the number of RBCs that contain oxyhemoglobin, which reduces the visibility of oxyhemoglobin. Oxyhemoglobin the combined state of oxygen that is to be delivered to peripheral tissues with the hemoglobin molecule that will carry it. 3. A nurse is collecting data on a recently admitted client. Which of the following techniques should the nurse use to measure tissue perfusion? a. Determining the client's respiratory rate b. Measuring the client's chest diameter c. Obtaining the client's level of oxygen saturation d. Checking the client's depth of respirations Answer is C-Obtaining the client's level of oxygen saturation -Obtaining the client's level of oxygen saturation is an appropriate technique of measuring perfusion. This item requires foundational thinking because you only need to identify which of the following options describes a technique for measuring tissue perfusion. Perfusion is the delivery or pumping of arterial blood through tissues or an organ. Oxygen saturation measures the percent of hemoglobin bound with oxygen that is being perfused through the arteries and into the tissues.
