Correct Answer: B

Rationale: Encouraging the client to discuss their compulsions is the best nursing intervention when caring for a client with OCD who spends excessive time on hand-washing. This approach can help the client identify underlying anxieties and triggers associated with the compulsive behavior. Restricting access to soap and water (Choice A) can lead to increased anxiety and worsen the obsession. Allowing the client to continue the behavior (Choice C) can perpetuate the compulsive cycle. Scheduling distracting activities (Choice D) may provide temporary relief but does not address the root cause of the behavior.

Correct Answer: C

Rationale: The correct answer is to report the symptoms to the healthcare provider immediately. Tardive dyskinesia is a serious side effect of antipsychotic medications, including haloperidol. Prompt reporting is crucial to evaluate the need for medication adjustment or change in treatment. Continuing the medication without intervention (choice A) can worsen the symptoms. Administering the next dose (choice B) is not appropriate when tardive dyskinesia is suspected. Educating the client (choice D) is important but not the priority when dealing with acute symptoms of tardive dyskinesia.

Correct Answer: B

Rationale: When a client being treated with lithium carbonate for bipolar disorder develops symptoms like diarrhea, vomiting, and drowsiness, it could indicate lithium toxicity. The appropriate action for the LPN/LVN is to notify the healthcare provider immediately of these symptoms before the next administration of the drug. This prompt communication is crucial to ensure that the healthcare provider can assess the situation, adjust the treatment plan if necessary, and prevent potential complications associated with lithium toxicity. Option A is incorrect because administering an antidote should be based on the healthcare provider's assessment. Option C is incorrect as these symptoms are not normal side effects and could indicate a serious issue. Option D is incorrect because refusing to administer the drug without consulting the healthcare provider could delay necessary interventions.

Correct Answer: B

Rationale: The correct action for the nurse to initiate is to take the client's vital signs and notify the physician immediately. These symptoms may indicate neuroleptic malignant syndrome, a rare but life-threatening reaction to antipsychotic medications, requiring immediate medical attention. Placing the client on seizure precautions and monitoring her frequently (Choice A) is not the most appropriate action in this situation. Describing the symptoms to the charge nurse and documenting them in the client's record (Choice C) delays prompt medical intervention. Choosing not to take any action (Choice D) is dangerous as the symptoms described suggest a serious condition that needs urgent evaluation and treatment.

Correct Answer: C

Rationale: Maintaining a consistent sodium intake is crucial for clients taking lithium because changes in sodium levels can impact lithium concentrations, potentially leading to toxicity. It is essential to avoid excessive sodium intake, as both low and high levels can affect lithium levels. Choices A, B, and D are incorrect. A high potassium diet is not a concern with lithium therapy. While taking lithium with food can help reduce gastrointestinal side effects, it is not the most important instruction. Finally, abruptly stopping lithium can lead to a recurrence of symptoms or a worsening of the condition, so it is vital to follow the prescribed regimen.
