Question 1 of 5
A nurse is caring for a patient who is being treated for leukemia in the hospital. The patient was able to maintain her nutritional status for the first few weeks following her diagnosis but is now exhibiting early signs and symptoms of malnutrition. In collaboration with the dietitian, the nurse should implement what intervention?
Correct Answer: C
Rationale: The correct answer is C: Provide the patient with several small, soft-textured meals each day. This intervention is appropriate for the patient showing early signs of malnutrition as it aims to increase the patient's nutrient intake in a manageable way. Small, soft-textured meals are easier for the patient to consume and digest, promoting better absorption of nutrients. This approach also aligns with the principle of promoting oral intake whenever possible before resorting to more invasive measures like TPN or PEG tube placement. Incorrect choices: A: Total parenteral nutrition (TPN) is typically reserved for patients who cannot tolerate oral feeding at all or have significant malabsorption issues. B: Percutaneous endoscopic gastrostomy (PEG) tube placement is usually considered if the patient cannot meet their nutritional needs orally in the long term. D: Assigning responsibility for the patient's nutrition to friends and family is not a sustainable or appropriate solution for addressing malnutrition in a hospitalized patient.
Question 2 of 5
A nurse is caring for a client who is about to begin factor VIII therapy to treat hemophilia A. When administering factor VIII, which of the following actions should the nurse take?
Correct Answer: D
Rationale: The correct answer is D because having emergency equipment ready is crucial due to the risk of allergic reactions or complications associated with factor VIII therapy. This includes supplies for managing anaphylaxis or other adverse reactions, such as epinephrine, antihistamines, and airway support. Administering the powdered form orally (A) is incorrect as factor VIII is given intravenously. Premedicating with aspirin (B) is contraindicated as aspirin can increase the risk of bleeding. Administering it via rapid IV bolus (C) is dangerous as it can lead to adverse effects like hypotension or clotting. Having emergency equipment ready ensures prompt and effective management of any potential complications.
Question 3 of 5
A nurse is caring for a client who is about to begin therapy with recombinant factor IX to treat hemophilia B. The client asks the nurse about the risk of disease transmission with recombinant factor IX as compared with plasma derived factor IX. The nurse should explain that the recombinant factor IX practically eliminates the risk for which of the following?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 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 5 of 5
The International Normalized Ratio (INR) was developed for the purpose of
Correct Answer: D
Rationale: Rationale: 1. INR standardizes PT results across labs. 2. Warfarin therapy requires close monitoring. 3. INR helps adjust warfarin dose accurately. 4. INR is not specific to heparin, oral anticoagulants, or screening for clotting system abnormalities. Summary: A: Heparin is monitored by aPTT. B: Oral anticoagulant therapy is monitored by INR. C: Intrinsic clotting abnormalities are not detected by INR. D: Warfarin therapy monitoring is standardized by INR.
