Nursing ANCC Adult Health Clinical Nurse Specialist Certification (ACNS) Sample Questions (Q27-Q32):

NEW QUESTION # 27
Which of the following managed care organizations has the LEAST control of managed care?

A. Staff/group Health Maintenance Organization (HMO).
B. Preferred provider organization.
C. Network Independent Practice Association (IPA).
D. Fee-for-service.

Answer: D

Explanation:
In the context of healthcare, the term "managed care" refers to a variety of techniques intended to reduce the cost of providing health benefits and improve the quality of care. It is characterized by arrangements with healthcare providers to provide care to members at reduced costs. These healthcare systems contrast significantly in terms of how much control they exert over services, costs, and the management of care.
Among the options provided-Network Independent Practice Association (IPA), Fee-for-service, Preferred Provider Organization (PPO), and Staff/Group Health Maintenance Organization (HMO)-the Fee-for-service (FFS) model has the least control over managed care. This is because the Fee-for-service model compensates providers for each service, such as tests and procedures, rather than providing care under a fixed fee or capitation system, which is common in other forms of managed care systems.
In a Fee-for-service system, healthcare providers are paid individually for each service they perform. This can lead to increased usage of healthcare services since providers are incentivized to perform more treatments and procedures as they will receive more payments. Consequently, there is less control over the overall use and cost of medical care, which contrasts with managed care models that seek to control costs and manage care more effectively through structured provider networks and set payment arrangements.
On the other hand, models like HMOs, PPOs, and IPAs have more structured systems. HMOs usually employ or partner closely with a network of providers to provide care for members at a fixed annual or monthly fee, thus controlling costs and managing care more tightly. PPOs, while allowing for more provider flexibility, still negotiate rates with providers and may offer incentives for members to use network providers. IPAs manage member care by contracting with independent physicians who continue to operate their own offices but must meet the IPA's standards and cost controls.
Thus, when comparing these models, the Fee-for-service system stands out as having the least control over managed care, focusing primarily on the volume of services rather than the coordination and overall management of patient care. This lack of control can lead to higher healthcare costs and less efficient care management.

NEW QUESTION # 28
What position should a patient be in before extubation?

A. Elevated at 30 degree.
B. Sitting at 45 degrees.
C. Sitting at 55 degrees.
D. Lying flat.

Answer: B

Explanation:
The recommended position for a patient before extubation is sitting at a 45-degree angle. This semi-upright position helps in several ways. First, it optimizes respiratory mechanics by allowing the diaphragm to move more freely, which can be particularly beneficial in improving the patient's ability to breathe independently once the tube is removed. This position also aids in the reduction of aspiration risks, as it prevents secretions from accumulating at the back of the throat, which could enter the lungs and cause an infection.
Before the process of extubation begins, it's crucial to ensure that the patient fully understands what the procedure will entail. Explaining the steps can help alleviate any anxiety or fear, ensuring cooperation, which is vital for a smooth extubation process. Clear communication about what to expect can also psychologically prepare the patient to retake control of their breathing, which is essential for a successful outcome.
Suctioning must be performed prior to extubation to clear any secretions from the airway. This step is critical because it minimizes the risk of blockage in the airway once the tube is removed, which can lead to breathing difficulties and potentially necessitate re-intubation. Ensuring the airway is clear also reduces the risk of pulmonary complications, such as pneumonia, which could arise from the aspiration of secretions.
Thus, positioning the patient at a 45-degree angle, along with proper explanation and suctioning before extubation, are key components in ensuring the safety and success of the procedure. These steps, combined with careful monitoring post-extubation, contribute to better recovery outcomes and comfort for the patient.

NEW QUESTION # 29
You are educating a patient about self-care when she returns home after CABG. She says she cannot wait to take a long tub bath. Which of the following is an appropriate response?

A. Tell the patient that tub baths must be avoided until her incision heals.
B. Show the patient how to keep her dressing dry.
C. Tell the patient to take tub baths when she feels ready to do so.
D. Tell the patient that she must avoid tub bathing for the first week at home.

Answer: D

Explanation:
In the context of postoperative care after Coronary Artery Bypass Grafting (CABG), it is important to ensure that the surgical incisions heal properly to prevent infection and promote optimal recovery. One of the key recommendations for patients returning home after CABG surgery is regarding their bathing habits, particularly concerning the type of baths they can take.
While patients who have undergone CABG are generally encouraged to resume certain normal activities, they need to take specific precautions with bathing. Although showering might be allowed shortly after discharge, tub baths are not recommended immediately. This is primarily because tub bathing involves prolonged immersion in water, which can potentially lead to the soaking of the surgical dressings and the incision sites. Keeping these areas dry is crucial to prevent the risk of infection and ensure the incisions heal properly.
Therefore, it is typically advised that CABG patients avoid tub baths for at least the first week after surgery. This timeframe allows the incisions to begin the healing process adequately before being exposed to the potential risks associated with longer exposure to water. Showering, on the other hand, can be controlled more easily to prevent the surgical sites from getting wet. Patients can use waterproof dressings or other protective methods to cover their incisions while showering.
In instructing a patient who is eager to take a tub bath, it is important to emphasize the reasons behind this restriction. Explain that while it is understandable they may want to relax in a bath, doing so could compromise their healing process. Patients should be made aware of how to keep their dressings dry during permissible activities like showering and be informed when it might be safe to resume other types of baths, based on their individual healing progress and the advice of their healthcare provider.
Ultimately, the goal of these instructions is to ensure that the patient's recovery is as smooth and complication-free as possible. Proper education about postoperative care, including details about bathing restrictions, plays a critical role in achieving this outcome.

NEW QUESTION # 30
Report ____ immediately if a patient has an EVD (external ventricular drain).

A. All of the above.
B. ICP.
C. CSF output.
D. Hypertension.

Answer: A

Explanation:
In patients with an external ventricular drain (EVD), monitoring and reporting intracranial pressure (ICP) is crucial. An EVD is typically used to measure ICP and to drain cerebrospinal fluid (CSF) to relieve pressure within the brain. Elevated ICP can indicate worsening of brain edema, hemorrhage, or other complications that could threaten the patient's life. Immediate reporting of abnormal ICP values ensures timely intervention to prevent severe brain injury or death.
Changes in CSF output should also be reported immediately. The rate of CSF drainage through an EVD can provide vital information about the current status of brain swelling or the presence of blood or infection in the CSF. Sudden increases, decreases, or cessation of CSF flow can indicate blockage, infection, or changes in brain tissue position, necessitating urgent medical attention.
Hypertension in patients with an EVD is a critical issue. Elevated blood pressure can exacerbate brain swelling and increase ICP, posing a significant risk of brain herniation. Conversely, hypotension can lead to reduced cerebral perfusion pressure and result in brain tissue ischemia. Both conditions require immediate adjustments in medical management, including the potential administration of vasoactive drugs to stabilize blood pressure.
Monitoring and immediate reporting of oxygen levels in patients with an EVD are essential. Hypoxia (low oxygen levels) can worsen brain injury by promoting further swelling and increasing ICP. Ensuring adequate oxygenation is a fundamental part of the care for patients with brain injuries and those with an EVD in place. Any deviations from normal oxygen levels should be addressed promptly to optimize brain recovery and function.
By closely monitoring these parameters-ICP, CSF output, blood pressure, and oxygen levels-and reporting any critical changes immediately, healthcare professionals can provide effective and responsive care to patients with an EVD, potentially improving outcomes in critical neurological conditions.

NEW QUESTION # 31
When weaning a patient from mechanical ventilation, you should consider returning the patient to the ventilator if which of the following occurs?

A. decreased VT
B. O2 desaturation by blood gas analysis or pulse oximetry
C. all of the above
D. increasing PaCO2

Answer: C

Explanation:
When weaning a patient from mechanical ventilation, there are several physiological changes and clinical signs that must be closely monitored to determine if the patient is ready to breathe independently or if they should be returned to ventilatory support. The process of weaning should be carefully managed, considering various factors that may indicate the patient's inability to maintain adequate respiratory function without assistance. Here are the key considerations:
**Decreased Tidal Volume (VT):** Tidal volume is the volume of air moved into and out of the lungs during each respiratory cycle. A significant decrease in tidal volume can be a sign that the patient is struggling to maintain adequate ventilation. This might happen due to muscle fatigue or worsening of the underlying respiratory condition. If the tidal volume falls below a critical threshold, it could lead to inadequate gas exchange and respiratory acidosis, necessitating the return to mechanical support.
**Increasing PaCO2:** An increase in arterial carbon dioxide (PaCO2) levels is a direct indicator of hypoventilation. During the weaning process, if the patient's PaCO2 levels begin to rise, it suggests that they are not able to adequately exhale CO2 due to reduced respiratory drive or muscle strength. This retention of CO2 can lead to respiratory acidosis, a dangerous condition requiring immediate intervention, potentially including reinstatement of mechanical ventilation.
**O2 Desaturation:** Monitoring oxygen saturation is crucial during the weaning process. Desaturation, detected either through blood gas analysis or pulse oximetry, indicates that the patient is not receiving enough oxygen. This could be due to a variety of reasons including inadequate lung mechanics, increased work of breathing, or underlying pulmonary pathology. Persistent low oxygen levels can cause vital organs to suffer from hypoxia, which is detrimental and necessitates reevaluation of the patient's readiness for weaning.
**Other Indications:** Besides the specific signs mentioned, several other clinical indicators should prompt consideration of returning a patient to ventilatory support. These include the development of new or worsening cardiac dysrhythmias, significant changes in blood pressure or heart rate, or other hemodynamic instability. These changes can reflect the patient's overall struggle or failure to adapt to reduced ventilatory support, indicating that the weaning process may be too aggressive or premature.
**Conclusion:** When considering whether to return a patient to mechanical ventilation, one must evaluate all these factors collectively. The choice to continue weaning or to reinstate mechanical support should be based on a comprehensive assessment of the patient's respiratory and cardiovascular status, ensuring that the decision supports the best possible outcome for the patient. Thus, when faced with the question of whether to return a patient to the ventilator, considering 'all of the above' reasons is a prudent approach.
