A nurse is caring for a client who has renal failure and is receiving epoetin. The nurse should monitor the client for which of the following adverse effects?
- A. Hypertension
- B. Muscle pain
- C. Edema
- D. Dry mouth
Correct Answer: A
Rationale: The correct answer is A: Hypertension. Epoetin is a medication used to stimulate red blood cell production in patients with renal failure. One of the potential adverse effects of epoetin therapy is an increase in blood pressure due to the rapid rise in red blood cell count. This can lead to hypertension. Monitoring for hypertension is crucial to prevent any complications. The other choices, muscle pain, edema, and dry mouth, are not directly associated with epoetin therapy in renal failure patients. Muscle pain could be a general issue but not specific to this medication. Edema is more commonly associated with fluid retention in renal failure, and dry mouth is not a typical adverse effect of epoetin therapy.

The nurse is staying with a patient who has been started on a blood transfusion. Which assessment should the nurse perform during a blood product infusion to detect a reaction?
- A. Vital signs
- B. Skin turgor
- C. Bowel sounds
- D. Pupil reactivity
Correct Answer: A
Rationale: The correct answer is A: Vital signs. During a blood transfusion, the nurse should monitor the patient's vital signs regularly to detect any signs of a transfusion reaction, such as fever, chills, rash, or hypotension. Vital signs provide crucial information about the patient's overall condition and can help the nurse identify and respond promptly to any adverse reactions. Skin turgor (B), bowel sounds (C), and pupil reactivity (D) are not directly related to monitoring for transfusion reactions and are not sensitive indicators of an adverse reaction during a blood transfusion. Monitoring vital signs is essential for patient safety and early detection of any complications during the transfusion process.
The nurse is reviewing the activated partial thromboplastin time for a patient receiving heparin. Which value indicates that the medication is within the therapeutic range?
- A. 2.5 to 9.5 minutes
- B. 9.5 to 11.3 seconds
- C. 1.5 to 2.0 times normal
- D. 2.0 to 3.0 times normal
Correct Answer: C
Rationale: The correct answer is C (1.5 to 2.0 times normal) because the therapeutic range for heparin is typically considered to be 1.5 to 2.5 times the normal value of activated partial thromboplastin time (aPTT). This range ensures adequate anticoagulation without increasing the risk of bleeding. Options A, B, and D are incorrect because they do not accurately reflect the therapeutic range for heparin. Option A provides a range in minutes, which is not a standard unit for aPTT measurement. Option B provides a range in seconds, which is too narrow for the therapeutic range of heparin. Option D provides a range in multiples of normal, but the upper limit of 3.0 times normal is higher than the typical upper limit of the therapeutic range for heparin.
A nurse is preparing to assist with a bone marrow biopsy. Which anatomical site should the nurse anticipate will be used to obtain the specimen?
- A. Ribs
- B. Humerus
- C. Posterior iliac crest
- D. Long bones in the legs
Correct Answer: C
Rationale: The correct answer is C: Posterior iliac crest. A bone marrow biopsy is commonly performed at the posterior iliac crest because it provides easy access to the bone marrow. This site has a high concentration of red bone marrow, making it an ideal location for obtaining a bone marrow specimen. The iliac crest is also a flat and easily accessible surface, which allows for safe and efficient insertion of the biopsy needle. Ribs (A) are not typically used due to the risk of puncturing the lungs. The humerus (B) is not a common site for bone marrow biopsy. Long bones in the legs (D) are not typically used due to the difficulty in accessing the bone marrow at those sites.
A nurse is caring for a client who is scheduled for an outpatient surgical procedure and reports taking aspirin 81 mg daily, including this morning. The nurse should identify that this places the client at risk for which of the following complications?
- A. Uncontrolled bleeding
- B. Myocardial infarction
- C. Respiratory depression
- D. Decreased renal perfusion
Correct Answer: A
Rationale: Rationale: Aspirin is an antiplatelet medication that inhibits platelet aggregation, increasing the risk of uncontrolled bleeding during surgical procedures. By taking aspirin, the client's blood clotting ability is impaired, leading to potential excessive bleeding during and after surgery. This can result in complications such as prolonged bleeding, hematoma formation, and delayed wound healing. Therefore, the correct answer is A: Uncontrolled bleeding.
Summary:
- B: Myocardial infarction is not directly related to taking aspirin; it is actually used to prevent heart attacks.
- C: Respiratory depression is not a common complication associated with aspirin use.
- D: Decreased renal perfusion is not a typical risk of taking aspirin; it primarily affects the cardiovascular system.
An oncology nurse is providing health education for a patient who has recently been diagnosed with leukemia. What should the nurse explain about commonalities between all of the different subtypes of leukemia?
- A. The different leukemias all involve unregulated proliferation of WBC
- B. The different leukemias all have unregulated proliferation of red blood cells and decreased bone marrow function.
- C. The different leukemias all result in a decrease in the production of white blood cells.
- D. The different leukemias all involve the development of cancer in the lymphatic system.
Correct Answer: A
Rationale: The correct answer is A because all subtypes of leukemia involve unregulated proliferation of white blood cells (WBC). Leukemia is a type of cancer that starts in the blood-forming tissues, leading to the production of abnormal WBCs in the bone marrow. This uncontrolled growth of WBCs interferes with the production of normal blood cells.
Choice B is incorrect because leukemia does not involve unregulated proliferation of red blood cells, but rather white blood cells. It also does not necessarily result in decreased bone marrow function as stated in the choice.
Choice C is incorrect because while some subtypes of leukemia may result in a decrease in the production of normal white blood cells, the primary issue is the unregulated proliferation of abnormal WBCs.
Choice D is incorrect because leukemia is not specifically related to cancer development in the lymphatic system. Leukemia primarily affects the bone marrow and blood.
