ATI NCLEX-RN Practice Questions Questions
Extract:
Question 1 of 5
During an intake assessment, the nurse asks the client if he has an advanced directive. The reason for asking the client this question is:
Correct Answer: B
Rationale: An advanced directive clarifies a client’s wishes for medical care, reducing confusion and conflict among family or healthcare providers, especially in critical situations. It does not address funeral plans, allow staff to make decisions, or permit euthanasia.
Question 2 of 5
The physician has prescribed Coumadin (sodium warfarin) for a client having transient ischemic attacks. Which laboratory test measures the therapeutic level of Coumadin?
Correct Answer: A
Rationale: Prothrombin time (PT/INR) measures Coumadin's anticoagulant effect by assessing clotting time. PTT monitors heparin, and clot retraction or bleeding time are unrelated.
Question 3 of 5
The nurse is caring for a 70-year-old client with hypovolemia who is receiving a blood transfusion. Assessment findings reveal crackles on chest auscultation and distended neck veins. What is the nurse's initial action?
Correct Answer: A
Rationale: Crackles and distended neck veins suggest fluid overload from the transfusion. Slowing the transfusion prevents worsening overload. Stopping it (
C) is premature, documenting only (
B) delays intervention, and pupil assessment (
D) is irrelevant.
Question 4 of 5
A six-month-old infant has been admitted to the emergency room with febrile seizures. In the teaching of the parents, the nurse states that:
Correct Answer: C
Rationale: The temperature elevation related to febrile seizures generally exceeds 101°F, and seizures occur during the temperature rise rather than after a prolonged elevation. Febrile seizures may recur and are more likely to do so when the first seizure occurs in the 1st year of life. There is little risk of neurological deficit, mental retardation, or altered behavior secondary to febrile seizures. Febrile seizures are associated with disease of the central nervous system.
Question 5 of 5
The physician of a client diagnosed with alcoholism orders neomycin 0.5 g q6h to prevent hepatic coma. Neomycin decreases serum ammonia levels by:
Correct Answer: A
Rationale: Neomycin interferes with protein synthesis in the bacterial cell, causing bacterial death. Neomycin reduces the growth of the ammonia-producing bacteria in the intestines and is used for the treatment of hepatic coma.
