When assisting with the placement of a pulmonary artery (PA) catheter, the nurse notes that the catheter is correctly placed when the monitor shows a:
- A. Typical PA pressure waveform.
- B. Tracing of the systemic arterial pressure.
- C. Tracing of the systemic vascular resistance.
- D. Typical PA wedge pressure (PAWP) tracing.
Correct Answer: D
Rationale: Step-by-step rationale for Answer D being correct:
1. PA catheter measures PA pressures.
2. PAWP reflects left atrial pressure.
3. Correct placement shows typical PAWP tracing.
4. PA pressure waveform (A) is not specific to PAWP.
5. Systemic arterial pressure tracing (B) is unrelated.
6. Systemic vascular resistance tracing (C) is not monitored by PA catheter.

A patient with terminal cancer reports a sudden onset of severe pain. Which intervention should the nurse implement first?
- A. Assess the patient’s pain using a standardized pain scale.
- B. Administer a PRN dose of prescribed analgesic.
- C. Notify the healthcare provider about the patient’s pain.
- D. Reposition the patient to enhance comfort.
Correct Answer: A
Rationale: The correct answer is A: Assess the patient’s pain using a standardized pain scale. The first step is to assess the severity and nature of the pain to determine the appropriate intervention. This allows the nurse to understand the pain intensity and characteristics, which guides the choice of analgesic and dosing. Administering analgesics (B) without proper assessment can lead to inappropriate treatment. Notifying the healthcare provider (C) is important but assessing the pain should come first. Repositioning the patient (D) may provide comfort but addressing the pain directly is the priority.
The nurse cites evidence-based practice as a rationale for a patient care decision. What isthe best description of evidence-based practice?
- A. Decisions based on expert legal testimony
- B. Use of best available research data
- C. Evolution of nursing practice over time
- D. Individual optimization of patient outcomes
Correct Answer: B
Rationale: The correct answer is B: Use of best available research data. Evidence-based practice involves integrating the best available research evidence with clinical expertise and patient values to make informed decisions about patient care. It emphasizes using scientifically proven data to guide practice and improve patient outcomes. Expert legal testimony (A) is not necessarily evidence-based. Evolution of nursing practice over time (C) does not specifically focus on research data. Individual optimization of patient outcomes (D) is a goal of evidence-based practice, but it does not fully encompass the concept.
Which interventions may be included during “terminal we aning”? (Select all that apply.)
- A. Complete extubation following ventilator withdrawal
- B. Discontinuation of artificial ventilation but maintenanc e of the artificial airway
- C. Discontinuation of anxiolytic and pain medications
- D. Titration of ventilator support based upon blood gas de terminations
Correct Answer: B
Rationale: The correct answer is B because during terminal weaning, the artificial ventilation is discontinued while maintaining the artificial airway to ensure comfort and support. This allows the patient to breathe on their own with support as needed.
Explanation:
1. Option A: Complete extubation following ventilator withdrawal may not be suitable during terminal weaning as it involves removing the breathing tube entirely.
2. Option C: Discontinuation of anxiolytic and pain medications may not always be appropriate during terminal weaning as it depends on the patient's comfort needs.
3. Option D: Titration of ventilator support based on blood gas determinations is not typically done during terminal weaning as the focus is on gradual withdrawal of ventilation support while maintaining comfort.
A client who is taking clonidine (Catapres, Duraclon) reports drowsiness. Which additional assessment should the nurse make?
- A. Has the client experienced constipation recently?
- B. Did the client miss any doses of the medication?
- C. How long has the client been taking the medication?
- D. Does the client use any tobacco products?
Correct Answer: C
Rationale: The correct answer is C. Assessing how long the client has been taking clonidine is crucial as drowsiness is a common side effect that typically improves over time as the body adjusts to the medication. This information helps determine if the drowsiness is a temporary side effect or a more concerning issue.
Choice A (constipation) is not directly related to drowsiness as a side effect of clonidine. Choice B (missed doses) may contribute to drowsiness but is not the primary assessment priority. Choice D (tobacco use) is not directly related to clonidine-induced drowsiness.
How should the nurse interprets these blood gas values? 2 3
- A. Compensated metabolic alkalosis
- B. Normal values
- C. Uncompensated respiratory acidosis
- D. Uncompensated respiratory alkalosis
Correct Answer: C
Rationale: The correct interpretation is uncompensated respiratory acidosis (Choice C) based on the values. Step 1: Evaluate pH - pH is <7.35, indicating acidosis. Step 2: Determine PaCO2 - PaCO2 is >45 mmHg, indicating respiratory cause. Step 3: Check HCO3- - HCO3- is within normal range, indicating uncompensated state. Choices A, B, and D are incorrect because they do not align with the given blood gas values.
