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.

The correct answer is choice c. “In my dreams, all I can see are the wounded reaching out and trying to grab me.”

Choice A rationale:

This statement indicates hypervigilance and paranoia, which can be symptoms of PTSD, but it is more indicative of a delusional disorder or severe anxiety.

Choice B rationale:

This statement reflects a possible delusion of grandeur or a coping mechanism to deal with trauma, but it does not directly indicate PTSD.

Choice C rationale:

This statement describes a recurring nightmare, which is a common symptom of PTSD. Individuals with PTSD often relive traumatic events through nightmares or flashbacks.

Choice D rationale:

This statement suggests a belief in a cause-and-effect relationship that may not be accurate. It could indicate guilt or a misunderstanding of the situation, but it is not a direct symptom of PTSD.
