Question 1
Regular
A patient has a nursing diagnosis of disturbed sleep pattern related to difficulty maintaining sleep state. Which of the following actions should the nurse include in the plan of care?
Correct!
Incorrect
The correct answer is: D
Rationale
D: Cluster nursing activities so that the patient has uninterrupted rest periods. This approach minimizes disruptions during sleep, allowing the patient to experience longer periods of rest, which is crucial for improving sleep quality.
A: Discontinue assessments during the night to allow uninterrupted sleep. Nighttime assessments may still be necessary for patient safety and health monitoring, making this option insufficient for comprehensive care.
B: Administer prescribed sedatives or opioids at bedtime to promote sleep. This can lead to dependency and potential complications, as relying solely on medication does not address underlying causes of sleep disturbances.
C: Silence monitor alarms to allow 30- to 40-minute rest periods. While this may enhance comfort temporarily, it compromises patient safety and monitoring, which are essential for effective nursing care.

Question 2
Regular
To determine the effectiveness of medications that a patient has received to reduce left ventricular afterload, which of the following hemodynamic parameters should the nurse monitor?
Correct!
Incorrect
The correct answer is: B
Rationale
Systemic vascular resistance (SVR) should be monitored to evaluate the effectiveness of medications aimed at reducing left ventricular afterload, as SVR directly reflects the resistance the heart must overcome to eject blood.
A: Central venous pressure (CVP) Measures the pressure in the thoracic vena cava, reflecting fluid status rather than the afterload faced by the left ventricle.
C: Pulmonary vascular resistance (PVR) Focuses on the resistance in the pulmonary circulation, which is not directly related to left ventricular afterload reduction assessment.
D: Pulmonary artery wedge pressure (PAWP) Primarily indicates left atrial pressure and overall fluid status, but does not specifically measure systemic vascular resistance or afterload.

Question 3
Regular
While family members are visiting, a patient has a cardiac arrest and is being resuscitated. Which of the following actions by the nurse is best?
Correct!
Incorrect
The correct answer is: A
Rationale
Ask family members if they wish to remain in the room during the resuscitation. This approach respects the family's autonomy, allowing them to make an informed decision about their involvement during a critical moment, which can help them process the situation better.
B: Explain to family members that watching the resuscitation will be very stressful. This option assumes the family's feelings without allowing them to express their preferences, potentially undermining their emotional involvement.
C: Assign a staff member to wait with family members just outside the patient room. While this provides support, it removes the family's choice to be present, which may be important for their emotional needs.
D: Escort family members quickly out of the patient room and then remain with them. This action lacks consideration for the family's wishes and may lead to feelings of exclusion during a traumatic event.

Question 4
Regular
The nurse is caring for a patient following surgery whose central venous pressure (CVP) monitor indicates low pressures. Which of the following actions should the nurse anticipate implementing?
Correct!
Incorrect
The correct answer is: A
Rationale
Increase the IV fluid infusion rate. This action is appropriate as low central venous pressure (CVP) often indicates inadequate circulating volume. Administering IV fluids can help restore normal pressure levels and improve hemodynamic stability.
B: Administer IV diuretic medications. Using diuretics would further decrease fluid volume, worsening the low CVP situation and potentially compromising the patient's cardiovascular status.
C: Elevate the head of the patient's bed to 45 degrees. While this position may aid in comfort, it does not address the underlying issue of low CVP, which requires fluid management.
D: Document the CVP and continue to monitor. Merely documenting and monitoring without taking action fails to address the critical need for intervention in response to low CVP readings.

Question 5
Regular
The nurse is caring for a patient with pulmonary hypertension. Which of the following parameters should the nurse monitor as an index of right ventricular afterload?
Correct!
Incorrect
The correct answer is: C
Rationale
Pulmonary vascular resistance (PVR) should be monitored as an index of right ventricular afterload. PVR directly reflects the resistance the right ventricle must overcome to pump blood into the pulmonary circulation, making it a crucial parameter in pulmonary hypertension management.
A: Mean arterial pressure (MAP) This parameter primarily assesses systemic arterial pressure and does not specifically indicate right ventricular afterload, which is more directly influenced by pulmonary vascular dynamics.
B: Central venous pressure (CVP) While CVP provides insight into right atrial pressure, it does not adequately represent the afterload faced by the right ventricle in pulmonary conditions.
D: Pulmonary artery wedge pressure (PAWP) PAWP is useful for evaluating left atrial pressure and left ventricular function, not for assessing the specific afterload on the right ventricle.

The nurse is assisting with insertion of a pulmonary artery (PA) catheter in a patient. Which of the following data identifies that the catheter is correctly placed?
Correct!
Incorrect
The correct answer is: A
Rationale
A: Monitor shows a typical PAOP tracing.
A typical PAOP tracing indicates that the pulmonary artery catheter is correctly placed within the pulmonary artery. This tracing reflects accurate pressure measurements, confirming the catheter's proper position vital for effective hemodynamic monitoring.
B: PA waveform is observed on the monitor.
While a PA waveform suggests catheter placement in the pulmonary artery, it does not specifically confirm correct positioning or accurate measurement of pulmonary artery occlusion pressure.
C: Systemic arterial pressure tracing appears on the monitor.
A systemic arterial pressure tracing indicates monitoring of the arterial system, not the pulmonary artery, thus failing to verify the catheter's correct placement within the intended pulmonary circulation.
D: Catheter has been inserted to the 22-cm marking on the line.
Insertion to a specific marking does not ensure correct placement within the pulmonary artery, as anatomical variations can result in inaccurate catheter positioning regardless of the marking's indication.

Question 11
Regular
The nurse is caring for a patient with a left radial arterial line. Which of the following assessments indicates a need for the nurse to take action?
Correct!
Incorrect
The correct answer is: A
Rationale
The left hand is cooler than the right hand.
This assessment suggests compromised blood flow to the left hand, which may indicate arterial occlusion or reduced perfusion. The arterial line's effectiveness could be jeopardized, necessitating prompt evaluation and potential intervention by the nurse to ensure adequate circulation and prevent tissue ischemia.
B: The mean arterial pressure (MAP) is 75 mm Hg. This MAP is within an acceptable range, indicating adequate perfusion pressure and does not necessitate immediate action from the nurse.
C: The system is delivering only 3 mL of flush solution per hour. While this may seem low, it is not inherently alarming unless there are signs of system malfunction or clotting.
D: The flush bag and tubing were last changed 3 days previously. Typically, a three-day duration is acceptable and does not immediately warrant concern unless there are signs of contamination or blockage.

Rationale
Inject air into the cuff until a slight leak is heard only at peak inflation. This method ensures that the cuff maintains adequate sealing during mechanical ventilation while minimizing the risk of over-inflation and potential tracheal damage.
A: Inflate the cuff until the pilot balloon is firm. A firm pilot balloon does not indicate optimal cuff inflation and may result in excessive pressure on the tracheal wall.
B: Inflate the cuff with a minimum of 10 mL of air. Using a fixed volume does not account for individual patient anatomy, potentially leading to inadequate or excessive cuff pressure.
C: Inject air into the cuff until a manometer shows 15 mm Hg pressure. This approach could cause over-inflation; individual variations in anatomy necessitate a more tailored inflation method to ensure safety.

Premature ventricular contractions (PVCs) occur while the nurse is suctioning a patient's endotracheal tube. Which of the following actions by the nurse is best?
Correct!
Incorrect
The correct answer is: B
Rationale
B: Stop and ventilate the patient with 100% oxygen. This action ensures immediate oxygen delivery to the patient, addressing potential hypoxia, which may contribute to the occurrence of PVCs during suctioning.
A: Decrease the suction pressure to 80 mm Hg. Lowering suction pressure does not effectively address the cardiac distress caused by PVCs and may not improve overall patient oxygenation.
C: Document the dysrhythmia in the patient's chart. While documentation is important, it does not provide immediate intervention to stabilize the patient's condition during the occurrence of PVCs.
D: Give prescribed PRN antidysrhythmic medications. Administering medications may not be the most immediate action, as ventilation with oxygen takes precedence in addressing the acute situation of PVCs.
Correct Answer: B

Question 19
Regular
Which of the following information obtained by the nurse when caring for a patient receiving mechanical ventilation indicates the need for suctioning?
Correct!
Incorrect
The correct answer is: A
Rationale
A: The respiratory rate is 17 breaths/minute.
In patients receiving mechanical ventilation, a respiratory rate of 17 breaths per minute may indicate adequate ventilation. However, the need for suctioning arises if the patient exhibits signs of distress or airway obstruction, which can lead to compromised oxygenation.
B: The pulse oximeter shows a SpO2 of 93%.
A SpO2 reading of 93% suggests mild hypoxemia, but it does not necessarily indicate immediate suctioning is required. Other assessments must inform the need for intervention.
C: The lungs have occasional audible expiratory wheezes.
Occasional wheezes can signify bronchospasm or airflow obstruction, but they do not automatically necessitate suctioning. Further evaluation is needed to determine the appropriate course of action.

The nurse notes thick, white respiratory secretions from a patient who is receiving mechanical ventilation. Which of the following interventions will be most effective in resolving this problem?
Correct!
Incorrect
The correct answer is: C
Rationale
C: Add additional water to the patient's enteral feedings. Increasing hydration through enteral feedings effectively thins respiratory secretions, promoting easier clearance and reducing the risk of airway obstruction in mechanically ventilated patients.
A: Suction the patient every hour. Frequent suctioning may irritate the airway, potentially increasing secretions rather than resolving the thick mucus problem in a mechanical ventilation context.
B: Reposition the patient every 2 hours. While repositioning can aid in lung expansion and secretion mobilization, it does not directly address the viscosity of the thick secretions present.
D: Instill 5 ml of sterile saline into the endotracheal tube (ET) before suctioning. This method can introduce fluid into the lungs, potentially leading to complications instead of effectively resolving the issue of thick secretions.
