Question 1 of 5
Four hours after mechanical ventilation is initiated for a patient with chronic obstructive pulmonary disease (COPD), the patient's arterial blood gas (ABG) results include a pH of 7.51, PaO₂ of 82 mm Hg, PaCO₂ of 26 mm Hg, and HCO₃ of 23 mEq/L (23 mmol/L). The nurse will anticipate the need to
Correct Answer: D
Rationale: Choice D as respiratory alkalosis (pH 7.51, PaCOâ‚‚ 26 mm Hg) from over-ventilation requires a lower rate. Increasing FIOâ‚‚ (choice A), volume (choice B), or rate (choice C) worsens alkalosis. This aligns with NCLEX physiological integrity, adjusting ventilation to normalize ABGs in COPD care.
Question 2 of 5
A 48-year-old patient with a comminuted fracture of the left femur has Buck's traction in place while waiting for surgery. To assess for pressure areas on the patient's back and sacral area and to provide skin care, the nurse should
Correct Answer: D
Rationale: Choice D as self-lifting maintains traction alignment while allowing skin assessment. Loosening traction (choice A) or turning (choices B, C) disrupts immobilization, risking fracture displacement. This aligns with NCLEX Safe and Effective Care Environment, balancing skin integrity with orthopedic stability in pre-surgical care.
Question 3 of 5
The day after a having a right below-the-knee amputation, a patient complains of pain in the right foot. Which action is best for the nurse to take?
Correct Answer: B
Rationale: Choice B as phantom pain, common post-amputation, requires immediate analgesia like other postoperative pain. Explaining (choice A) or predicting relief (choice D) doesn't address current distress, and loosening bandages (choice C) risks bleeding. This aligns with NCLEX Physiological Integrity, prioritizing pain management in acute care.
Question 4 of 5
A patient who arrives at the emergency department experiencing severe left knee pain is diagnosed with a patellar dislocation. The initial patient teaching by the nurse will focus on the need for
Correct Answer: C
Rationale: Choice C as realignment of a patellar dislocation requires anesthesia, the initial focus. Immobilization (choice A), flexion (choice B), and restrictions (choice D) follow. This reflects NCLEX Physiological Integrity, prioritizing procedural preparation in emergency care.
Question 5 of 5
When a patient arrives in the emergency department with a facial fracture, which action will the nurse take first?
Correct Answer: C
Rationale: Choice C as cervical spine stabilization is first due to fracture-associated risks. Bleeding (choice A), ice (choice B), or orientation (choice D) follow. This reflects NCLEX Physiological Integrity, prioritizing spinal safety in trauma.
