When monitoring the effectiveness of treatment for a patient with a large anterior wall myocardial infarction, the most important information for the nurse to obtain is:
- A. Central venous pressure (CVP).
- B. Systemic vascular resistance (SVR).
- C. Pulmonary vascular resistance (PVR).
- D. Pulmonary artery wedge pressure (PAWP).
Correct Answer: D
Rationale: The correct answer is D: Pulmonary artery wedge pressure (PAWP). This is crucial in monitoring a patient with a large anterior wall myocardial infarction as it provides information on left ventricular function and fluid status. A high PAWP may indicate left ventricular failure or fluid overload, requiring immediate intervention.
A: Central venous pressure (CVP) is not as specific for assessing left ventricular function and may not provide accurate information in this scenario.
B: Systemic vascular resistance (SVR) is important in assessing systemic blood flow, but it may not directly indicate left ventricular function in this case.
C: Pulmonary vascular resistance (PVR) is more relevant in conditions affecting the pulmonary circulation and may not be as immediately informative in assessing left ventricular function in this context.

What is the focus of the synergy model of practice?
- A. Allowing unrestricted visiting for the patient 24 hours aebaircbh.c odma/tye.s t
- B. Providing holistic and alternative therapies.
- C. Considering the needs of patients and their families, w hich drives nursing competency.
- D. Addressing the patients’ needs for energy and support.
Correct Answer: C
Rationale: The correct answer is C because the synergy model of practice emphasizes considering the needs of patients and their families, which in turn drives nursing competency. This approach recognizes that patient care is not just about the individual but also about the broader support system. This holistic viewpoint helps nurses tailor their care to meet the unique needs of each patient and their family, ultimately leading to better outcomes.
Choices A, B, and D are incorrect:
A: Allowing unrestricted visiting for the patient 24 hours is not directly related to the focus of the synergy model which is more about patient-centered care.
B: Providing holistic and alternative therapies is a valid approach, but it is not the primary focus of the synergy model.
D: Addressing the patients' needs for energy and support is important but does not capture the comprehensive nature of the synergy model which encompasses the needs of both patients and their families.
Which statement is true regarding venous thromboembolisambir b(.VcoTm/Ete)s ta nd pulmonary embolus (PE)?
- A. PE should be suspected in any patient who has unexpla ined cardiorespiratory complaints and risk factors for VTE.
- B. Bradycardia and hyperventilation are classic symptom s of PE.
- C. Dyspnea, chest pain, and hemoptysis occur in nearly a ll patients with PE.
- D. Most critically ill patients are at low risk for VTE and PE and do not require prophylaxis.
Correct Answer: A
Rationale: The correct answer is A because PE should be suspected in patients with unexplained cardiorespiratory complaints and risk factors for VTE. This is important because PE can present with nonspecific symptoms, making it crucial to consider it in the differential diagnosis.
Explanation:
1. PE can present with various symptoms, including dyspnea, chest pain, and hemoptysis, but these are not present in all patients.
2. Bradycardia and hyperventilation are not classic symptoms of PE, as it can present with tachycardia and other respiratory findings.
3. Critically ill patients are actually at higher risk for VTE and PE, so prophylaxis is typically recommended.
In summary, choice A is correct because it emphasizes the importance of considering PE in patients with cardiorespiratory complaints and risk factors for VTE, while the other choices contain inaccuracies or incomplete information.
When assessing the patient for hypoxemia, the nurse recognizes what as an early sign of the effect of hypoxemia on the cardiovascular system?
- A. Heart block
- B. Restlessness
- C. Tachycardia
- D. Tachypnea
Correct Answer: C
Rationale: The correct answer is C: Tachycardia. Hypoxemia results in decreased oxygen levels in the blood, stimulating the body to increase heart rate to improve oxygen delivery. Tachycardia is an early sign of the cardiovascular system compensating for hypoxemia. Heart block (A) is a disruption in the electrical conduction within the heart and is not directly related to hypoxemia. Restlessness (B) is a non-specific sign and can be caused by various factors. Tachypnea (D) is an increased respiratory rate, which is a response to hypoxemia but not a direct effect on the cardiovascular system.
A patient is having difficulty weaning from mechanical ve ntilation. The nurse assesses the patient and notes what potential cause of this difficult weaning?
- A. Cardiac output of 6 L/min
- B. Hemoglobin of 8 g/dL
- C. Negative sputum culture and sensitivity
- D. White blood cell count of 8000
Correct Answer: B
Rationale: The correct answer is B: Hemoglobin of 8 g/dL. Low hemoglobin levels can lead to inadequate oxygen delivery to tissues, causing respiratory distress and difficulty weaning from mechanical ventilation. This is due to reduced oxygen-carrying capacity leading to increased work of breathing.
A: Cardiac output of 6 L/min is within normal range and not directly related to difficulty weaning from mechanical ventilation.
C: Negative sputum culture and sensitivity indicate absence of respiratory infection but not a direct cause of difficulty weaning.
D: White blood cell count of 8000 is within normal range and not a direct cause of difficulty weaning.
The nurse is caring for a mechanically ventilated patient an d is charting outside the patient’s room when the ventilator alarm sounds. What is the priorit y order for the nurse to complete these actions? (Put a comma and space between each answer choice.)
- A. Check quickly for possible causes of the alarm that can be fixed.
- B. After troubleshooting, connect back to mechanical venti lator and reassess patient.
- C. Go to patient’s bedside.
- D. Manually ventilate the patient while getting respiratory therapist.
Correct Answer: C
Rationale: Step-by-step rationale for why choice C is correct:
1. Going to the patient’s bedside is the priority as it allows the nurse to assess the patient's condition directly.
2. By being at the bedside, the nurse can quickly evaluate the patient's breathing, vital signs, and other indicators for immediate action.
3. Direct assessment enables timely intervention and avoids delays in addressing potential life-threatening situations.
4. Checking for possible causes of the alarm and reconnection to the ventilator can follow, but assessing the patient's immediate needs takes precedence.
In summary, choice C is correct because direct patient assessment is the fundamental step in responding to a ventilator alarm to ensure patient safety and timely intervention. Choices A, B, and D are incorrect as they focus on troubleshooting and technical aspects before directly assessing the patient's condition.
