Question 1 of 5
Which of the following is NOT a clinical sign of Hemolytic anemia:
Correct Answer: A
Rationale: Cyanosis is the bluish discoloration of the skin or mucous membranes due to insufficient oxygen in the blood. It is not a typical clinical sign of hemolytic anemia. Hemolytic anemia is characterized by the premature destruction of red blood cells, leading to symptoms such as abdominal pain, hemoglobinuria (presence of hemoglobin in the urine), jaundice (yellowing of the skin and eyes), and sometimes lower back pain due to kidney involvement. Cyanosis is more commonly associated with respiratory or cardiovascular conditions where oxygen levels are affected.

Question 3 of 5
A patient reports having adverse effects with nicotinic acid (niacin). The nurse can suggest performing which action to minimize these undesirable effects?
Correct Answer: D
Rationale: Taking an aspirin tablet 30 minutes before taking nicotinic acid (niacin) can help minimize the undesirable effects such as flushing, itching, and rash. Aspirin helps to reduce these side effects by blocking the prostaglandin synthesis that mediates the flushing response associated with niacin therapy. This intervention can improve medication adherence and tolerance in patients who experience discomfort with nicotinic acid therapy.
Question 4 of 5
A client is prescribed clonidine (Catapres) for hypertension. Which statement by the client indicates effective teaching?
Correct Answer: C
Rationale: Clonidine, an alpha-2 agonist, lowers BP but risks rebound hypertension if stopped abruptly. Tapering off shows understanding, preventing this danger. Stopping if normal or extra doses risk instability. Chewing isn't advised'oral absorption suffices. Tapering aligns with clonidine's withdrawal risk, critical in hypertension management, making C the statement of effective teaching.
Question 5 of 5
The nurse is caring for a patient who is receiving warfarin (Coumadin) and notes bruising and petechiae on the patient™s extremities. The nurse will request an order for which laboratory test?
Correct Answer: B
Rationale: The nurse should request an order for a platelet level to assess the patient's platelet count. Warfarin (Coumadin) is an anticoagulant medication that works by interfering with the blood clotting process. Bruising and petechiae may be signs of decreased platelet count or impaired platelet function. Monitoring the platelet level will help determine if the patient's symptoms are related to thrombocytopenia (low platelet count). While the International Normalized Ratio (INR) is commonly used to monitor the effects of warfarin therapy, in this case, the presence of bruising and petechiae suggest a need to assess platelet levels specifically. PT and aPTT tests assess the clotting function of factors produced by the liver and are not directly related to platelet count. Vitamin K level may be tested in cases of suspected vitamin K deficiency, but it would not directly help in assessing
