Chapter 29: Management of Patients with Nonmalignant Hematologic Disorders Prep U

The nurse is caring for a client with type 2 diabetes who take metformin to manage glucose levels. The nurse recognizes the client may be most at risk for which vitamin deficiency?

B12 Explanation: The medication metformin (Glucophage) increases the client's risk for developing B12 deficiency because the medication inhibits the absorption of B12

A client with megaloblastic anemia reports mouth and tongue soreness. What instruction will the nurse give the client regarding eating while managing the client's symptoms? "Eat small amounts of bland, soft foods frequently." "Eat larger amounts of bland, soft foods less frequently." "Eat cold, bland foods with a large amount of water." "Eat low-fiber blended foods only."

Because the client with megaloblastic anemia often reports mouth and tongue soreness, the nurse should instruct the client to eat small amounts of bland, soft foods frequently. The other answer choices do not factor in the client's mouth soreness or need for nutrition. - Mouth and tongue soreness may impair nutritional intake. The nurse may instruct the patient to choose soft bland foods that are less likely to cause further discomfor

A patient with end-stage kidney disease (ESKD) has developed anemia. What laboratory finding does the nurse understand to be significant in this stage of anemia?

Creatinine level of 6 mg/100 mL The degree of anemia in patients with end-stage renal disease varies greatly; however, in general, patients do not become significantly anemic until the serum creatinine level exceeds 3 mg/100 mL.

The nurse is caring for a client with external bleeding. What is the nurse's priority intervention? Elevation of the extremity Pressure point control Direct pressure Application of a tourniquet

Direct pressure Explanation: Applying direct pressure to an injury is the initial step in controlling bleeding. Elevation reduces the force of flow, but direct pressure is the first step. The nurse may use pressure point control for severe or arterial bleeding. Pressure points (those areas where large blood vessels can be compressed against bone) include femoral, brachial, facial, carotid, and temporal artery sites. The nurse should avoid applying a tourniquet unless all other measures have failed, because it may further damage the injured extremity.

A client with anemia has been admitted to the medical-surgical unit. Which assessment findings are characteristic of iron deficiency anemia? Nights sweats, weight loss, and diarrhea Dyspnea, tachycardia, and pallor Nausea, vomiting, and anorexia Itching, rash, and jaundice

Dyspnea, tachycardia, and pallor Explanation: Signs of iron deficiency anemia include dyspnea, tachycardia, and pallor, as well as fatigue, listlessness, irritability, and headache. Night sweats, weight loss, and diarrhea may signal acquired immunodeficiency syndrome. Nausea, vomiting, and anorexia may be signs of hepatitis B. Itching, rash, and jaundice may result from an allergic or hemolytic reaction.

The nurse observes the laboratory studies for a client in the hospital with fatigue, feeling cold all of the time, and hemoglobin of 8.6 g/dL and a hematocrit of 28%. What finding would be an indicator of iron-deficiency anemia? Erythrocytes that are microcytic and hypochromic Erythrocytes that are macrocytic and hyperchromic Clustering of platelets with sickled red blood cells An increased number of erythrocytes

Erythrocytes that are microcytic and hypochromic Explanation: A blood smear reveals erythrocytes that are microcytic (smaller than normal) and hypochromic (lighter in color than normal). It does not reveal macrocytic (larger than normal) or hyperchromic erythrocytes. Clustering of platelets with sickled red blood cells would indicate sickle cell anemia. An increase in the number of erythrocytes would indicate polycythemia vera. pg 910

When assessing a client with a disorder of the hematopoietic or the lymphatic system, which assessment is most essential?

Health history, such as bleeding, fatigue, or fainting Explanation: When assessing a client with a disorder of the hematopoietic or the lymphatic system, it is essential to assess the client's health history. An assessment of drug history is essential because some antibiotics and cancer drugs contribute to hematopoietic dysfunction. Aspirin and anticoagulants may contribute to bleeding and interfere with clot formation. Because industrial materials, environmental toxins, and household products may affect blood-forming organs, the nurse needs to explore exposure to these agents. Menstrual history, age, gender, and lifestyle assessments, such as exercise routines and habits, do not directly affect the hematopoietic or lymphatic system

The most common cause of iron-deficiency anemia in premenopausal women includes which of the following? Menorrhagia Inadequate iron supplementation Iron malabsorption Lack of vitamin B12

Menorrhagia Explanation: The most common cause of iron deficiency anemia in premenopausal women is menorrhagia. In pregnancy, it may be caused by inadequate intake of iron. Iron malabsorption may occur following a gastrectomy or with celiac disease. Lack of vitamin B12 is also a potential cause of anemia.

A nurse cares for a client with aplastic anemia. Which laboratory results will the nurse expect to find with this client? Select all that apply. Neutrophil count 1200/microliter Hemoglobin 7 g/dL Platelets 35,000 microliters White blood cell count 10,000/microliter Neutrophil count 17,000/microliter

Neutrophil count 1200/microliter Hemoglobin 7 g/dL Platelets 35,000 microliters Aplastic anemia causes pancytopenia, or overall decrease to all myeloid stem cell-derived cells. Pancytopenia manifests as neutrophil count less than 1500/microliter, hemoglobin less than 10 g/dL, and platelets less than 50,000/microliter.

During preparation for bowel surgery, a client receives an antibiotic to reduce intestinal bacteria. The nurse knows that hypoprothrombinemia may occur as a result of antibiotic therapy interfering with synthesis of which vitamin? Vitamin A Vitamin D Vitamin E Vitamin K

Vitamin K Explanation: Intestinal bacteria synthesize such nutritional substances as vitamin K, thiamine, riboflavin, vitamin B12, folic acid, biotin, and nicotinic acid. Antibiotic therapy may interfere with synthesis of these substances, including vitamin K. Intestinal bacteria don't synthesize vitamins A, D, or E.

A nurse caring for a client who has hemophilia is getting ready to take the client's vital signs. What should the nurse do before taking a blood pressure? Ask if taking a blood pressure has ever produced bleeding under the skin or in the arm joints. Ask if taking a blood pressure has ever produced pain in the upper arm. Ask if taking a blood pressure has ever caused bruising in the hand and wrist. Ask if taking a blood pressure has ever produced the need for medication.

ask if taking a blood pressure has ever produced bleeding under the skin or in the arm joints. Explanation: Due to the client's enhanced risk for bleeding, before taking a blood pressure, the nurse asks the client if the use of a blood-pressure cuff has ever produced bleeding under the skin or in the arm joints. pg 936

A thin client is prescribed iron dextran intramuscularly. What is most important action taken by the nurse when administering this medication? Employs the Z-track technique Uses a 23-gauge needle Injects into the deltoid muscle Rubs the site vigorously

employ z tract method When iron medications are given intramuscularly, the nurse uses the Z-track technique to avoid local pain and staining of the skin. The gluteus maximus muscle is used. The nurse avoids rubbing the site vigorously and uses a 18- or 20-gauge needle.
