A nurse is teaching a group of clients about St. John's wort.
Which of the following pieces of information should the nurse include in the teaching?
"St. John's wort can be used to treat severe depression."
"St. John's wort can lower prostate-specific antigen levels."
"St. John's wort increases estrogen levels in the body."
"St. John's wort can reduce the effectiveness of oral contraceptives.".
The Correct Answer is D
The correct answer is choice d. “St. John’s wort can reduce the effectiveness of oral contraceptives.”
Choice A rationale:
St. John’s wort is commonly used to treat mild to moderate depression. It has been shown to be effective in alleviating symptoms of depression, likely due to its impact on neurotransmitters like serotonin.
Choice B rationale:
There is no evidence to suggest that St. John’s wort can lower prostate-specific antigen (PSA) levels. PSA levels are typically monitored for prostate health, and St. John’s wort does not have an impact on these levels.
Choice C rationale:
St. John’s wort does not increase estrogen levels in the body. It primarily affects neurotransmitters and has no known effect on hormone levels.
Choice D rationale:
St. John’s wort can indeed reduce the effectiveness of oral contraceptives. It induces certain liver enzymes that can increase the metabolism of contraceptive hormones, thereby reducing their effectiveness and increasing the risk of unintended pregnancy.

Correct Answer is A
Explanation
Choice A rationale:
Protecting the client from injury is the highest priority nursing action in this scenario. Here's a detailed rationale explaining the importance of this action:
1. Imminent Risk of Harm:
Acute anxiety can significantly impair judgment and impulse control, escalating the risk of self-harm or harm to others. It's crucial to prevent any actions that could result in physical injury, even if unintended.
2. Physiological Manifestations:
Anxiety can trigger physiological responses that heighten the potential for harm, such as: Increased heart rate and blood pressure
Hyperventilation Diaphoresis
Agitation and restlessness Dissociation
These physiological changes can contribute to accidents, falls, or other injuries.
3. Impaired Decision-Making:
Acute anxiety often clouds rational thinking and decision-making abilities.
Individuals may engage in behaviors they wouldn't consider in a calmer state, such as running away, lashing out, or attempting self-harm.
The nurse's role is to safeguard the client from potential consequences of these impulsive actions.
4. Establishing Safety as a Foundation for Care:
Ensuring physical safety creates a necessary foundation for subsequent interventions.
Once safety is established, the nurse can proceed with assessing coping skills, identifying anxiety triggers, and implementing therapeutic strategies.
5. Protecting Others:
In rare cases, acute anxiety can manifest in aggression towards others.
The nurse must protect not only the client but also other individuals who may be at risk.
6. Ethical and Legal Obligations:
Nurses have a professional duty to protect clients from harm, upholding ethical principles and legal standards of care.
7. Preventing Trauma:
Physical injuries sustained during a crisis can exacerbate anxiety and complicate recovery. Proactive safety measures aim to prevent further trauma and promote healing.
I'll provide detailed rationales for the other choices in separate messages to ensure clarity and comprehensiveness.
Correct Answer is C
Explanation
Choice A rationale:
While it's true that the nurse has released the client's information without their explicit consent, this action is justified under the duty to warn and protect.
This duty supersedes the general obligation to maintain confidentiality when there's a serious and imminent threat to identifiable individuals or the public.
In this case, the client's verbal threat to bomb a local church constitutes a credible and foreseeable risk of harm, necessitating the breach of confidentiality to protect potential victims.
Choice B rationale:
Although the nurse's actions may help to avoid malpractice charges by demonstrating responsible care and adherence to ethical obligations, this is not the primary reason for notifying the minister.
The primary goal is to avert harm and fulfill the duty to warn, not to shield oneself from legal liability.
Choice C rationale:
This is the correct answer. The nurse has acted in accordance with the duty to warn and protect, which is a legal and ethical obligation in healthcare.
This duty mandates that healthcare professionals take reasonable steps to warn potential victims and protect the public when a patient communicates a serious threat of harm.
Choice D rationale:
While confidentiality is a cornerstone of healthcare ethics, it's not absolute.
The duty to warn and protect allows for limited breaches of confidentiality when necessary to prevent serious harm, as in this case.
The nurse's actions align with ethical principles and legal requirements, even though they involve disclosing confidential information.
