A nurse is preparing to administer diphenhydramine 50 mg PO every 6 hr to a client who has acute dystonia. The available medication is diphenhydramine 25 mg tablets.

How many tablets should the nurse administer per dose?

Choice A rationale: The client’s magnesium level is 1.7 mg/dL, which is below the normal range of 1.8 to 2.4 mg/dL. Hypomagnesemia can cause neuromuscular irritability, muscle weakness, tremors, and even seizures or cardiac arrhythmias in severe cases.

It’s often associated with other electrolyte imbalances such as hypokalemia and hypocalcemia.

In the context of anorexia nervosa, this could be due to inadequate dietary intake, malabsorption, or excessive losses from the gastrointestinal tract.

Choice B rationale: The client’s chloride level is 98 mmol/L, which falls within the normal range of 96 to 106 mmol/L. Chloride is an important electrolyte that helps maintain acid-base balance, fluid balance, and is a component of gastric juice as hydrochloric acid.

There’s no immediate concern regarding the client’s chloride level.

Choice C rationale: The client’s phosphate level is 2.5 mg/dL, which is below the normal range of 2.8 to 4.5 mg/dL. Hypophosphatemia can lead to muscle weakness, bone pain, mental changes, and potentially life-threatening complications such as respiratory failure and heart failure.

In the context of anorexia nervosa, hypophosphatemia is a common complication during refeeding due to shifts in electrolytes.

Choice D rationale: The client’s potassium level is 3.5 mmol/L, which is at the lower end of the normal range of 3.5 to

5.0 mmol/L. Hypokalemia can cause muscle weakness, cramps, arrhythmias, and in severe cases, it can be life- threatening.

In the context of anorexia nervosa, this could be due to inadequate dietary intake, excessive losses due to vomiting or laxative abuse, or shifts in electrolytes during refeeding.

In conclusion, the nurse should follow up on the client’s magnesium, phosphate, and potassium levels due to their potential implications on the client’s health, especially considering the client’s current health status and the process of refeeding.

Choice A rationale:

1. Understanding OCD:

OCD is a chronic mental health condition characterized by intrusive thoughts (obsessions) and repetitive behaviors (compulsions).

Individuals with OCD feel compelled to perform rituals to relieve anxiety or prevent perceived harm, even if they recognize the behaviors as excessive or irrational.

Rituals can consume significant time and interfere with daily functioning.

2. Rationale for Choice A:

Acknowledges the client's needs: Planning for rituals demonstrates understanding and acceptance of the client's experience, fostering trust and rapport.

Reduces anxiety: Allowing time for rituals can temporarily reduce anxiety, making the client more receptive to other interventions.

Gradual approach: It's a stepping stone towards Exposure and Response Prevention (ERP), the gold-standard treatment for OCD.

Enhances control: Scheduling rituals can help the client feel more in control, reducing the urge to engage in them compulsively.

3. Addressing potential concerns:

Reinforcing rituals: While there's a possibility of temporarily reinforcing rituals, it's a necessary first step to build trust and engagement in therapy.

Interfering with treatment: Scheduling rituals is a part of a comprehensive treatment plan that includes ERP and other therapies to address the underlying causes of OCD.

4. Importance of individualized care:

The specific approach to planning for rituals should be tailored to the client's unique needs, preferences, and severity of symptoms.

Collaboration with the client is essential to ensure their active participation in treatment. I'll now address the rationales for the incorrect choices:

Choice B rationale:

Setting strict limits on behaviors can be counterproductive: Triggers anxiety and distress

Impedes trust and therapeutic alliance Diminishes sense of control

Heightens resistance to treatment

Choice C rationale:

Confronting the client about the senselessness of rituals is ineffective and potentially harmful: Exacerbates anxiety and shame

Alienates the client

Disregards the involuntary nature of OCD Undermines motivation for treatment Choice D rationale:

Isolating the client is unethical and detrimental:

Increases distress and loneliness Impedes therapeutic interactions Reinforces negative self-perceptions

Lacks evidence of efficacy in OCD treatment
