A mental health nurse on an inpatient eating disorders unit is caring for a client who has anorexia nervosa and has a body mass index of 16.7. Which of the following actions should the nurse take? (Select all that apply.)

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.

Rationale for Choice A:

While it is important to address the client's behavior, simply explaining that it was unacceptable is unlikely to be effective in this situation. Clients with antisocial personality disorder often have difficulty understanding and accepting responsibility for their actions. They may lack empathy for others and may not see their behavior as problematic. Confronting the client about their behavior too early in the therapeutic relationship could lead to defensiveness, hostility, or even aggression. It is important to first establish a rapport with the client and build a foundation of trust before addressing difficult topics.

Rationale for Choice B:

Setting behavioral limits is an important aspect of treatment for clients with antisocial personality disorder. However, it is not the first priority in this situation. Before setting limits, the nurse needs to establish a relationship with the client and assess their individual needs and level of functioning. Attempting to set limits without first establishing a rapport could lead to power struggles and further resistance from the client.

Rationale for Choice C:

Exploring the truth of the client's statements may be necessary at some point in the treatment process. However, it is not the first priority in this situation. The nurse's initial focus should be on establishing a relationship with the client and assessing their immediate needs. Focusing on the accuracy of the client's statements too early in the therapeutic process could derail the development of a trusting relationship.

Rationale for Choice D:

Establishing a client relationship is the first and most important step in the treatment of any client, but it is especially crucial for clients with antisocial personality disorder. These clients often have difficulty trusting others and forming close relationships. By establishing a rapport with the client, the nurse can begin to build trust and create a safe and supportive environment. This foundation is essential for any further therapeutic interventions to be successful.
