Extract:
Question 1 of 5
A nurse is caring for a client who is unconscious and has a breathing pattern characterized by alternating periods of hyperventilation and apnea. The nurse should document that the client has which of the following respiratory alterations?
Correct Answer: B
Rationale: Cheyne-Stokes respirations involve alternating hyperventilation and apnea, often seen in neurological or heart failure conditions.
Question 2 of 5
Which statement by the nurse when explaining the purpose of positive end-expiratory pressure (PEEP) to the patient's caregiver is accurate?
Correct Answer: A
Rationale: PEEP maintains alveolar patency at the end of expiration, preventing collapse and improving oxygenation.

Question 3 of 5
A client is admitted to the emergency room with a respiratory rate of 7/min. Arterial blood gases (ABG) reveal the following values. Which of the following is an appropriate analysis of the ABGS?
Correct Answer: C
Rationale: Low pH and elevated PaCO2 indicate respiratory acidosis due to hypoventilation retaining carbon dioxide.

Question 4 of 5
A nurse is evaluating the central venous pressure (CVP) of a client who has sustained multiple traumas. Which of the following interpretations of a low CVP pressure should the nurse make?
Correct Answer: C
Rationale: Low CVP indicates reduced venous return, consistent with hypovolemia from trauma-related blood loss.
Question 5 of 5
A patient with septic shock has a BP of 70/46 mm Hg, pulse of 136 beats/min, respirations of 32 breaths/min, temperature of 104°F, and blood glucose of 246 mg/dL. Which intervention ordered by the health care provider should the nurse implement first?
Correct Answer: C
Rationale: Fluid resuscitation with normal saline is the priority in septic shock to address hypotension and restore perfusion.
