Which statement reflects adherence to current recommendations concerning open visitation policies?
- A. Allowing animals on the unit; however, these can only be “therapy” animals through the hospital’s pet therapy program.
- B. Allowing family visitation throughout the day except a t change of shift and during rounds.
- C. Determining, in collaboration with the patient and famaiblyirb, .cwomho/te csta n visit and when.
- D. Permitting open visitation by adults 18 years of age and older; limit visits of children to 1 hour.
Correct Answer: C
Rationale: The correct answer is C because it reflects patient-centered care by involving patients and families in decision-making. Collaborating with them on visitation preferences promotes a supportive environment. Choice A restricts animal visitation, not addressing human visitors. Choice B limits visitation during specific times, not individualized. Choice D imposes restrictions based on age, not on patient/family preferences. Therefore, Choice C is the most aligned with current recommendations for open visitation policies.

Following insertion of a central venous catheter, the nurse obtains a stat chest x-ray film to verify proper catheter placement. The radiologist reports to the nurse: “The tip of the catheter is located in the superior vena cava.” What is the best inter pretation of these results by the nurse?
- A. The catheter is not positioned correctly and should be removed.
- B. The catheter position increases the risk of ventricular daybisrbr.hcoymth/tmesti as.
- C. The distal tip of the catheter is in the appropriate position.
- D. The physician should be called to advance the catheter into the pulmonary artery.
Correct Answer: C
Rationale: The correct answer is C: The distal tip of the catheter is in the appropriate position.
Rationale:
1. The superior vena cava is a desirable location for a central venous catheter tip placement as it is close to the heart for rapid medication delivery.
2. Catheter tip in the superior vena cava allows for proper venous return and minimizes the risk of complications.
3. The nurse does not need to remove or adjust the catheter if the tip is in the superior vena cava.
4. Advancing the catheter into the pulmonary artery (option D) would be incorrect as it can lead to serious complications.
Incorrect choices:
A: Incorrect because placement in the superior vena cava is acceptable.
B: Incorrect as placement in the superior vena cava does not increase the risk of ventricular dysrhythmias.
D: Incorrect as advancing the catheter into the pulmonary artery is unnecessary and risky.
A patient in the ICU is recovering from open-heart surgery. The nurse enters his room and observes that his daughter is performing effleurage on his arms and talking in a low voice about an upcoming family vacation that is planned. The room is dimly lit, and she hears the constant beeping of his heart monitor. From the hall she hears the cries of a patient in pain. Which of the following are likely stressors for the patient? Select all that apply.
- A. His daughters conversation
- B. His daughters effleurage
- C. The beeping of the heart monitor
- D. The dim lighting of the room
Correct Answer: C
Rationale: The correct answer is C: The beeping of the heart monitor is a likely stressor for the patient recovering from open-heart surgery in the ICU. The constant beeping can cause anxiety and uncertainty about their health status. The daughter's conversation and effleurage are likely comforting and supportive for the patient, reducing stress. The dim lighting may create a calming environment, and the distant cries of a patient in pain may evoke empathy but may not directly stress the recovering patient. Therefore, the beeping of the heart monitor stands out as a stressor among the choices provided.
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.
The nurse wishes to enhance sleep cycles in her critically ill patient. Research has shown that which nursing action improves sleep in critically ill patients?
- A. Repositioning every 2 hours
- B. Hypnotic medications
- C. Five-minute back effleurage
- D. Adequate pain control
Correct Answer: D
Rationale: The correct answer is D: Adequate pain control. Pain can significantly disrupt sleep in critically ill patients. By ensuring adequate pain control, the nurse can help improve the patient's ability to rest and sleep. This intervention targets a key factor affecting sleep cycles in critically ill patients. Repositioning every 2 hours (A) may help prevent pressure ulcers but does not directly address sleep improvement. Hypnotic medications (B) may have adverse effects and are not recommended as a first-line intervention. Five-minute back effleurage (C) may provide temporary relaxation but is not as effective as adequate pain control in improving sleep quality.
A patient with respiratory failure has arterial pressure-based cardiac output (APCO) monitoring and is receiving mechanical ventilation with peak end-expiratory pressure (PEEP) of 12 cm H2O. Which information indicates that a change in the ventilator settings may be required?
- A. The arterial pressure is 90/46.
- B. The heart rate is 58 beats/minute.
- C. The stroke volume is increased.
- D. The stroke volume variation is 12%.
Correct Answer: A
Rationale: The correct answer is A. A decrease in the arterial pressure (hypotension) with a low diastolic pressure (46 mmHg) may indicate inadequate perfusion, possibly due to inadequate cardiac output from the mechanical ventilation. This suggests that a change in ventilator settings may be required to improve oxygenation and perfusion.
Option B is incorrect because a heart rate of 58 beats/minute alone does not provide direct information on the patient's hemodynamic status. Option C is incorrect as an increased stroke volume would usually be a positive indicator; it does not necessarily indicate a need for changing the ventilator settings. Option D is incorrect as a stroke volume variation of 12% is within normal limits and does not necessarily require a change in ventilator settings.
