Extract:
Question 1 of 5
The nurse in the emergency department is caring for a client who was involved in a motor vehicle collision. Which of the following diagnostic test results would best determine the client's oxygenation and ventilation status?
Correct Answer: B
Rationale: Arterial blood gas provides the most accurate assessment of oxygenation (PaO2) and ventilation (PaCO2) post-collision. Peak flow assesses asthma, pulse oximetry measures oxygen saturation only, and CT evaluates structure.
Question 2 of 5
Which of the following statements describes what the nurse must know in order to provide anticipatory guidance to parents of a toddler about readiness for toilet training?
Correct Answer: B
Rationale: Myelination of the spinal cord is completed by this age, enabling voluntary sphincter control between 18 to 24 months.
Question 3 of 5
While sitting in the cafeteria, a nurse overhears two students discussing a client admitted for chemical detoxification. The nurse should:
Correct Answer: C
Rationale: Confronting the students addresses the breach of confidentiality directly and educates them. Reporting to the teacher or supervisor escalates unnecessarily, and ignoring the behavior allows the violation to persist.
Question 4 of 5
The client has been receiving garamycin 65 mg IVPB every 8 hours for the past 6 days. Which lab result indicates an adverse reaction to the medication?
Correct Answer: D
Rationale: Garamycin (gentamicin) is an aminoglycoside antibiotic that can cause nephrotoxicity. A serum creatinine level of 2.0 mg/dL is elevated (normal range is approximately 0.6-1.2 mg/dL), indicating potential kidney damage, an adverse reaction. Answers A, B, and C represent normal or unrelated lab values.
Question 5 of 5
The client is scheduled for a paracentesis. What should the nurse expect to do prior to the procedure?
Correct Answer: B
Rationale: Having the client void before paracentesis prevents bladder puncture during the procedure. Catheter insertion, NPO status, or enemas are not typically required.
