Correct Answer: C

Rationale: Benztropine (Cogentin) is an anticholinergic medication used to treat extrapyramidal symptoms, such as restlessness and muscle rigidity, which are common side effects of antipsychotic medications like haloperidol. Tactile hallucinations and reports of hearing disturbing voices are symptoms of schizophrenia that would typically be addressed by the antipsychotic medication (haloperidol) itself. Tardive dyskinesia, a potential side effect of long-term antipsychotic use, would require discontinuation of the antipsychotic medication rather than administration of benztropine.

Correct Answer: D

Rationale: You should explain that fetal station is the level of the fetus's presenting part in relationship to the mother's ischial spines. Fetal station is measured in terms of the number of centimeters above or below the mother's ischial spines. When the fetus is 1 to 5 centimeters above the ischial spines, the fetal station is -1 to -5, and when the fetus is 1 to 5 centimeters below the level of the maternal ischial spines, the fetal station is +1 to +5. Choices A, B, and C provide incorrect information about fetal lie, presentation, and attitude, respectively, which do not align with the definitions of these terms in obstetrics.

Correct Answer: A

Rationale: Spasms of the muscles of the tongue, face, neck, and back are indicative of acute dystonia, an extrapyramidal manifestation associated with loxapine use. Acute dystonia is a serious condition that can lead to airway obstruction and respiratory compromise. Therefore, the nurse should prioritize reporting this finding to prevent potential harm to the client. Orthostatic hypotension, dry mouth, and increased appetite are common side effects of antipsychotic medications but are not as immediately life-threatening as acute dystonia. Monitoring and managing these side effects are essential for the client's overall well-being, but they do not pose the same level of urgency as addressing acute dystonia.

Correct Answer: B

Rationale: Polyuria is a crucial early indication of lithium toxicity. It results from the drug's effect on the kidneys, leading to increased urine output. This is a significant symptom to monitor as it can indicate potential toxicity. Constipation, rash, and tinnitus are not typically associated with early indications of lithium toxicity. Constipation is more commonly seen as a side effect of some medications, while rash and tinnitus are not specific indicators of lithium toxicity.

Correct Answer: C

Rationale: The correct answer is C. When a client is receiving a monoamine oxidase inhibitor (MAOI), they should avoid foods high in tyramine to prevent a hypertensive crisis. Cheese, beer, and products with chocolate are rich in tyramine and can interact with MAOIs, leading to a dangerous rise in blood pressure. Choices A, B, and D do not contain high levels of tyramine and are not typically restricted when taking MAOIs.
