Extract:
Question 1 of 5
A nurse is assessing a client who has heart failure and is taking furosemide. Which of the following findings should indicate to the nurse that the client is experiencing fluid volume deficit?
Correct Answer: D
Rationale: Furosemide is a diuretic; an elevated hematocrit level indicates fluid volume deficit due to hemoconcentration.
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: Dopamine is used in septic shock to increase blood pressure; hypotension indicates the infusion rate may need to be increased to achieve therapeutic effect.
Question 3 of 5
A nurse is preparing to transcribe a prescription for a client that reads 'ondansetron 8 mg by mouth every 12 hr PRN.' Which of the following parts of the prescription should the nurse clarify with the provider?
Correct Answer: D
Rationale: The term PRN (as needed) does not specify the circumstances under which the medication should be given, requiring clarification from the provider to ensure appropriate administration.
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: PT measures the time it takes for blood to clot, and it is particularly relevant for clients taking warfarin because warfarin works by inhibiting the synthesis of certain clotting factors, including factors II, VII, IX, and X, which are involved in the PT pathway. Monitoring PT levels helps ensure that the client is receiving an appropriate dose of warfarin to prevent clot formation without causing excessive bleeding.
Question 5 of 5
A nurse is caring for a client who started haloperidol five days ago and is experiencing neuroleptic malignant syndrome. Which of the following prescriptions should the nurse anticipate administering?
Correct Answer: C
Rationale: Bromocriptine, a dopamine agonist, is used to treat neuroleptic malignant syndrome by counteracting dopamine receptor blockade.
