Question 1 of 5
A nurse is reviewing the laboratory data of a client who is receiving filgrastim. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the treatment?
Correct Answer: D
Rationale: The correct answer is D: WBC count. Filgrastim is a medication that stimulates the production of white blood cells (WBCs). Monitoring the WBC count is essential to evaluate the effectiveness of the treatment, as an increase in WBC count indicates that the medication is working to boost the immune system. Monitoring potassium level (
A), BUN (
B), and INR (
C) are not directly related to evaluating the effectiveness of filgrastim treatment. Potassium level is typically monitored for cardiac function, BUN for kidney function, and INR for monitoring anticoagulant therapy.
Therefore, the WBC count is the most appropriate laboratory value to assess the response to filgrastim.
Question 2 of 5
A nurse is assessing a client who has septic shock and is receiving dopamine by continuous IV infusion. Which of the following findings indicates that the nurse should increase the rate of infusion?
Correct Answer: B
Rationale: The correct answer is B: Hypotension. In septic shock, the body's blood pressure drops significantly, leading to hypotension. Dopamine is a vasopressor that helps increase blood pressure by constricting blood vessels.
Therefore, if the client's blood pressure remains low despite being on dopamine, it indicates that the current rate of infusion is not sufficient to maintain adequate perfusion to vital organs. Increasing the rate of infusion would help improve blood pressure and perfusion.
Choices A, C, and D are incorrect as they are not directly related to the need for increasing the dopamine infusion rate in septic shock.
Question 3 of 5
A nurse is caring for a client in the post-anesthesia unit who is experiencing malignant hyperthermia. Which of the following prescriptions should the nurse anticipate administering?
Correct Answer: D
Rationale: The correct answer is D: Dantrolene. Malignant hyperthermia is a potentially life-threatening condition triggered by certain anesthetics. Dantrolene is the specific antidote for malignant hyperthermia as it works to inhibit calcium release from the sarcoplasmic reticulum, preventing muscle contraction and reducing body temperature. Verapamil (
A) is a calcium channel blocker and not indicated for malignant hyperthermia. Naloxone (
B) is an opioid antagonist used for opioid overdose, not for malignant hyperthermia. Cefazolin (
C) is an antibiotic used for infection, not for malignant hyperthermia.
Therefore, the correct choice is Dantrolene (
D) for treating malignant hyperthermia.
Question 4 of 5
A nurse is preparing to administer a scheduled dose of warfarin to a client. Which of the following laboratory tests should the nurse review prior to administration?
Correct Answer: A
Rationale: The correct answer is A: PT (Prothrombin Time). PT is used to monitor warfarin therapy as it measures the extrinsic pathway of the clotting process, which warfarin affects. Monitoring PT helps ensure the client is within the therapeutic range to prevent bleeding or clotting complications.
Total iron-binding capacity (
B) is unrelated to warfarin therapy. WBC (
C) is a white blood cell count, not relevant for warfarin monitoring. PTT (
D) is used to monitor heparin therapy, not warfarin.
Question 5 of 5
A nurse is caring for a client who is receiving ondansetron IV. Which of the following findings is an indication that the ondansetron is effective?
Correct Answer: A
Rationale: The correct answer is A: Decreased nausea. Ondansetron is an antiemetic medication used to treat nausea and vomiting.
Therefore, if the client is receiving ondansetron IV and their nausea is decreased, it indicates that the medication is effective in managing their symptoms. Reduced dizziness (
B) and absence of peripheral neuropathy (
D) are not direct indicators of ondansetron effectiveness. Increased urinary output (
C) is not related to the medication's mechanism of action.
