Question 1 of 5
A nurse is administering epoetin intravenously to a client who has renal failure. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The correct answer is B: Administer via IV bolus over 1 to 3 min. This is the correct action because epoetin is typically administered intravenously over a specified time frame to prevent adverse reactions such as rapid changes in blood pressure or heart rate. Shaking the vial before using (option A) is unnecessary and may lead to frothing. Diluting the drug with D5W (option C) is not recommended for administration as an IV bolus. Saving the used vial for the next dose (option D) is incorrect and violates medication safety protocols. Administering via IV bolus over 1 to 3 min ensures safe and effective delivery of the medication.
Question 2 of 5
According to the FAB classification, the L2 stage is characterized by:
Correct Answer: C
Rationale: The correct answer is C because according to the FAB classification, the L2 stage is characterized by large homogenous blasts with scanty nucleoli and a higher nucleus to cytoplasm ratio. This stage represents acute lymphoblastic leukemia with a high risk of relapse. Choice A is incorrect as it describes the L1 stage. Choice B is incorrect as it describes the L3 stage. Choice D is incorrect as it does not accurately describe the characteristics of the L2 stage.
Question 3 of 5
The nurse is concerned that a patient is demonstrating signs of red blood cell production. What laboratory value did the nurse most likely use to make this decision?
Correct Answer: B
Rationale: The correct answer is B: Bilirubin. Elevated levels of bilirubin can indicate increased red blood cell breakdown or hemolysis, prompting the body to produce more red blood cells to compensate for the loss. Iron (A) is involved in red blood cell production but is not a direct indicator. Thrombin (C) is a clotting factor, not related to red blood cell production. Intrinsic factor (D) is necessary for vitamin B12 absorption, not directly linked to red blood cell production. Therefore, Bilirubin is the most likely laboratory value used to indicate increased red blood cell production.
Question 4 of 5
A patient has an altered level of T and B cells. The nurse realizes that these cells are members of which cell type?
Correct Answer: C
Rationale: The correct answer is C: Lymphocytes. T and B cells are types of lymphocytes, a crucial component of the immune system responsible for fighting infections. T cells regulate immune responses, while B cells produce antibodies. Platelets (A), eosinophils (B), and red blood cells (D) are not involved in immune responses and do not possess the functions of T and B cells. Platelets are involved in blood clotting, eosinophils are a type of white blood cell involved in allergic reactions, and red blood cells are responsible for oxygen transport.
Question 5 of 5
A patient has a bone marrow aspiration from the posterior iliac crest. Before the procedure, the patient's vital signs were: blood pressure 132/82 mm Hg and pulse 88 beats/min. One hour after the procedure, the blood pressure is 108/70 mm Hg and pulse is 96 beats/min. Which assessment is the least important for the patient at this time?
Correct Answer: B
Rationale: The correct answer is B: Check the patient's most recent complete blood count report. This assessment is the least important at this time because changes in vital signs post-bone marrow aspiration are more indicative of immediate complications such as bleeding or shock, which require prompt attention. Checking the complete blood count report would not provide immediate actionable information in this acute situation. Summary: A: Observing the puncture site is important for signs of bleeding or infection. C: Asking the patient about lightheadedness or dizziness is crucial to assess for signs of hypovolemia or shock. D: Determining if the patient had any medications before the procedure is essential to identify possible adverse drug interactions.
