The AACN Standards for Acute and Critical Care Nursing Practice uses what framework to guide critical care nursing practice?
- A. Evidence-based practice
- B. Healthy work environment
- C. National Patient Safety Goals
- D. Nursing process
Correct Answer: A
Rationale: The correct answer is A: Evidence-based practice. The AACN Standards for Acute and Critical Care Nursing Practice emphasize the use of evidence-based practice to guide critical care nursing. This framework ensures that nursing interventions are based on the best available evidence, leading to improved patient outcomes. Healthy work environment (B) and National Patient Safety Goals (C) are important but not specific frameworks for critical care nursing. The nursing process (D) is a systematic approach to delivering patient care but is not the primary guiding framework in critical care nursing practice.

Which action will the nurse need to do when preparing to assist with the insertion of a pulmonary artery catheter?
- A. Determine if the cardiac troponin level is elevated.
- B. Auscultate heart and breath sounds during insertion.
- C. Place the patient on NPO status before the procedure.
- D. Attach cardiac monitoring leads before the procedure.
Correct Answer: D
Rationale: The correct answer is D: Attach cardiac monitoring leads before the procedure. This is essential to monitor the patient's cardiac rhythm and detect any abnormalities during catheter insertion. Cardiac monitoring leads provide real-time information on the patient's heart rate and rhythm, allowing the nurse to promptly address any complications.
A: Determining if the cardiac troponin level is elevated is not directly related to assisting with pulmonary artery catheter insertion.
B: Auscultating heart and breath sounds during insertion is important but does not take precedence over attaching cardiac monitoring leads.
C: Placing the patient on NPO status before the procedure may be necessary for other procedures, but it is not specifically required for assisting with pulmonary artery catheter insertion.
A patient on mechanical ventilation is experiencing severe agitation due to being on the ventilator. Which nursing intervention would be best?
- A. Performing breathing exercises with the patient
- B. Offering the patient a patient-controlled analgesic device
- C. Asking the physician to prescribe an antianxiety medication
- D. Offering the patient the patients own MP3 player to listen to
Correct Answer: B
Rationale: The correct answer is B: Offering the patient a patient-controlled analgesic device. This intervention allows the patient to self-administer pain relief, which can help alleviate discomfort associated with mechanical ventilation and reduce agitation. Breathing exercises (choice A) may not address the root cause of agitation. Asking for antianxiety medication (choice C) may not be immediate or ideal due to potential side effects. Offering an MP3 player (choice D) may provide distraction but may not effectively address the agitation caused by the ventilator.
assessment, the patient is restless, heart rate has increased to 110 beats/min, respirations are 36 breaths/min, and blood pressure is 156/98 mm Hg. The cardiac monitor shows sinaubsir bt.acocmh/ytecsat rdia with 10 premature ventricular contractions (PVCs) per minute. Pulmonary artery pressures are elevated. The nurse suctions the patient and obtains pink, frothy secretio ns. Loud crackles are audible throughout lung fields. The nurse notifies the physician, w ho orders an ABG analysis, electrolyte levels, and a portable chest x-ray study. How d oes the nurse interpret the following blood gas levels? pH 7.28 PaCO 46 mm Hg Bicarbonate 22 mEq/L PaO 58 mm Hg O saturation 88% 2
- A. Hypoxemia and compensated respiratory alkalosis
- B. Hypoxemia and uncompensated respiratory acidosis
- C. Normal arterial blood gas levels
- D. Normal oxygen level and partially compensated metabaobliribc.c aomci/dteosts is
Correct Answer: B
Rationale: The correct answer is B: Hypoxemia and uncompensated respiratory acidosis.
Step-by-step rationale:
1. pH is low (7.28), indicating acidosis.
2. PaCO2 is elevated (46 mm Hg), indicating respiratory acidosis.
3. PaO2 is low (58 mm Hg), indicating hypoxemia.
4. Bicarbonate is within normal range (22 mEq/L), suggesting no compensation for the acidosis.
5. Oxygen saturation is low (88%), supporting the presence of hypoxemia.
Summary:
A: Incorrect - pH is low, not indicating compensated alkalosis.
C: Incorrect - Various abnormalities in the blood gas levels are present.
D: Incorrect - There is hypoxemia and uncompensated acidosis, not metabolic alkalosis.
The charge nurse is supervising care for a group of patients monitored with a variety of invasive hemodynamic devices. Which patient should the charge nurse evaluate first?
- A. A patient with a central venous pressure (RAP/CVP) oafb i6rb .mcomm/ teHstg and 40 mL of urine output in the past hour
- B. A patient with a left radial arterial line with a BP of 11 0/60 mm Hg and slightly dampened arterial waveform
- C. A patient with a pulmonary artery occlusion pressure of 25 mm Hg and an oxygen saturation of 89% on 3 L of oxygen via nasal cannula
- D. A patient with a pulmonary artery pressure of 25/10 mm Hg and an oxygen saturation of 94% on 2 L of oxygen via nasal cannula
Correct Answer: C
Rationale: The correct answer is C because a pulmonary artery occlusion pressure of 25 mm Hg indicates possible fluid overload or cardiac issue requiring urgent evaluation. This value is high, suggesting increased pressure in the left side of the heart. Additionally, the oxygen saturation of 89% on 3 L of oxygen indicates potential respiratory compromise. This patient needs immediate assessment and intervention to prevent worsening of their condition.
Choice A is incorrect as a central venous pressure of 6 mm Hg is within normal limits, and the urine output is adequate. Choice B is incorrect as a BP of 110/60 mm Hg is acceptable, and a slightly dampened arterial waveform is not an immediate concern. Choice D is incorrect as a pulmonary artery pressure of 25/10 mm Hg is within normal range, and an oxygen saturation of 94% on 2 L of oxygen is acceptable.
Which of the following statements about comfort care is aacbcirubr.caotme/?te st
- A. Withholding and withdrawing life-sustaining treatment are distinctly different in the eyes of the legal community.
- B. Each procedure should be evaluated for its effect on the patient’s comfort before being implemented.
- C. Only the patient can determine what constitutes comfo rt care for him or her.
- D. Withdrawing life-sustaining treatments is considered e uthanasia in most states.
Correct Answer: C
Rationale: Step 1: Comfort care is focused on providing relief from suffering and improving quality of life.
Step 2: Patient-centered care emphasizes the individual's preferences and values.
Step 3: Patient autonomy is a fundamental principle in healthcare decision-making.
Step 4: Patients have the right to determine what constitutes comfort care for themselves.
Step 5: Therefore, statement C is correct as it aligns with the patient's autonomy and individualized care approach.
Summary:
- Choice A is incorrect because legal distinctions between withholding and withdrawing treatment may vary.
- Choice B is incorrect as it focuses on evaluating procedures rather than the patient's preferences.
- Choice D is incorrect as withdrawing life-sustaining treatments is not universally considered euthanasia.
