A client's PaCO2 is abnormal on an ABG report.
What does the nurse suspect as the most likely medical diagnosis?
Sexually Transmitted Infection (STI).
Chronic Obstructive Pulmonary Disease (COPD).
Congestive Heart Failure (CHF).
Chronic Renal Insufficiency or Failure (CRF).
The Correct Answer is B
Choice A rationale
Sexually Transmitted Infections (STIs) primarily affect the reproductive system and do not directly cause abnormalities in PaCO2 levels. PaCO2 reflects the partial pressure of carbon dioxide in arterial blood, which is a key indicator of respiratory function and acid-base balance.
Choice B rationale
Chronic Obstructive Pulmonary Disease (COPD) is a group of lung diseases that obstruct airflow, leading to impaired gas exchange. This impaired exchange often results in the retention of carbon dioxide, causing an elevated PaCO2 level on an ABG report, indicating respiratory acidosis.
Choice C rationale
Congestive Heart Failure (CHF) primarily affects the cardiovascular system, leading to fluid overload and potential pulmonary congestion. While severe CHF can indirectly affect gas exchange, the most direct and common cause of abnormal PaCO2 is a respiratory issue like COPD.
Choice D rationale
Chronic Renal Insufficiency or Failure (CRF) primarily affects the kidneys' ability to regulate electrolytes and waste products. While CRF can lead to metabolic acidosis, which can trigger respiratory compensation (altering PaCO2), it is not the most direct or likely cause of an abnormal PaCO2 level on an ABG report.

Correct Answer is ["A","B"]
Explanation
Choice A rationale
Nurse practice acts, established at the state level, delineate the scope of nursing practice. They define the specific actions, duties, and responsibilities that nurses are legally authorized to perform based on their education, licensure, and experience. These acts also outline what activities fall outside the permissible boundaries of nursing practice to protect patient safety and maintain professional standards.
Choice B rationale
A primary objective of state nurse practice acts is to safeguard the public by regulating the practice of nursing. Through licensure requirements, standards of care, and disciplinary procedures, these acts ensure that only qualified and competent individuals provide nursing care. This regulation helps to maintain accountability within the profession and protect patients from potential harm due to unqualified or unethical practice.
Choice C rationale
The regulation of nursing practice primarily falls under the jurisdiction of individual state governments, not the federal government. Each state has its own board of nursing or similar regulatory body that is responsible for developing and enforcing the state's nurse practice act. While federal laws may influence healthcare, the direct oversight and regulation of nursing licensure and practice are state responsibilities.
Choice D rationale
Student nurses are held to the same standards of care as licensed nurses when providing patient care. Although they are still in the learning process and work under supervision, they are expected to adhere to established safety protocols and ethical principles. Their actions can have consequences, and they are accountable for the care they provide, just as licensed nurses are.
Choice E rationale
If a student nurse faces disciplinary action by a state board of nursing due to violations of nursing practice standards or unprofessional conduct, it can indeed impact their eligibility to take the National Council Licensure Examination (NCLEX). State boards have the authority to determine who is eligible for licensure, and disciplinary actions can lead to delays or even prohibition from taking the examination, depending on the severity of the infraction.
Correct Answer is D
Explanation
Choice A rationale
Expressing remorse indicates an awareness of the negative consequences of past actions, which aligns with the valuing process step of choosing, where the individual recognizes the value and impact of different choices. However, it doesn't fully demonstrate prizing, which involves cherishing and affirming the value.
Choice B rationale
Explaining how past choices contributed to the renal failure demonstrates understanding and cognitive processing of the situation, aligning with the choosing step of the valuing process, where the individual intellectually recognizes the value. However, it doesn't necessarily indicate an emotional investment or affirmation of new values.
Choice C rationale
Stating an intention to adopt new behaviors reflects the acting step of the valuing process, where the individual commits to and implements the chosen values in their actions. While important for change, it doesn't directly demonstrate the internal valuing or cherishing of these new actions.
Choice D rationale
Expressing pride in gaining knowledge and skills to manage diabetes signifies that the client now holds this self-management in high regard and finds personal worth in it. This aligns with the prizing step of the valuing process, where the individual emotionally embraces and values the new belief or behavior, leading to a sense of satisfaction and affirmation.
