NCLEX RN Predictor Exam Questions
Extract:
Question 1 of 5
Which one of the following lab tests should be done periodically if the client is being maintained on warfarin sodium (Coumadin)?
Correct Answer: A
Rationale: Warfarin’s anticoagulant effect is monitored by INR (derived from prothrombin time), but periodic platelet counts are also checked to assess for thrombocytopenia, a potential side effect. White cell, neutrophil, and basophil counts are less relevant.
Question 2 of 5
The child with iron poisoning is given IV deferoxamine mesylate (Desferal). Following administration, the child suffers hypotension, facial flushing, and urticaria. The initial nursing intervention would be to:
Correct Answer: B
Rationale: The IV line should not be discontinued because other IV medications will be needed. Stop the medication and begin a normal saline infusion. The child is exhibiting signs of an allergic reaction and could go into shock if the medication is not stopped. The line should be kept opened for other medication. Taking vital signs and reporting to the physician is not an adequate intervention because the IV medication continues to flow. Assessing urinary output and, if it is 30 mL an hour, maintaining current treatment is an inappropriate intervention owing to the child's obvious allergic reaction.
Question 3 of 5
Which of the following meal selections is appropriate for the client with celiac disease?
Correct Answer: C
Rationale: Celiac disease requires a gluten-free diet. Rice Krispies bars are typically gluten-free, unlike toast, cookies, or pizza, which contain wheat flour.
Question 4 of 5
Which vitamin should be administered with INH (isoniazid) in order to prevent possible nervous system side effects?
Correct Answer: C
Rationale: Isoniazid can cause peripheral neuropathy by depleting vitamin B6 (pyridoxine), so supplemental pyridoxine is given to prevent this side effect.
Question 5 of 5
A client admitted to the emergency room with multiple injuries develops Cullen's sign. The nurse is aware that the client has sustained damage to the:
Correct Answer: C
Rationale: Cullen’s sign (periumbilical bruising) indicates intra-abdominal bleeding, often from trauma to abdominal organs like the liver or spleen. It is not associated with brain, lung, or spinal injuries.
