Muscle rigidity and stiffness

constipation and dry mouth

Tachycardia and hypotension

Reports of photosensitivity

Answer and Explanation

The Correct Answer is B

a. Muscle rigidity and stiffness: This is correct because muscle rigidity and stiffness are signs of extrapyramidal symptoms (EPS), which benztropine is prescribed to treat.
b. Constipation and dry mouth: These are common side effects of antipsychotics but do not warrant benztropine, which is specifically used to manage EPS.
c. Tachycardia and hypotension: These are not related to the EPS that benztropine treats. They may require other interventions.
d. Reports of photosensitivity: Photosensitivity is not related to EPS and does not require benztropine.

Correct Answer is A

Explanation

a. "There is a chemical imbalance of the brain, which leads to altered perceptions." Schizophrenia is a complex mental health disorder with a strong biological component. While the exact cause is unknown, it's believed to involve abnormalities in brain chemistry and neurotransmitters. This is a general explanation that avoids going into too much detail but acknowledges the biological basis of hallucinations.
b. "The hallucinations are caused by medication interactions." Hallucinations are a core symptom of schizophrenia and not necessarily caused by medication interactions.
c. "There is too little serotonin in the brain, causing delusions and hallucinations." While serotonin might be involved in schizophrenia, it's not the only neurotransmitter implicated.
d. Abnormal hormonal changes have precipitated auditory hallucinations." Hormonal changes might influence mood, but they are not the primary cause of auditory hallucinations in schizophrenia.

A. Food is rapidly ingested without proper chewing. B. Purging causes the depletion of dietary calcium. C. Poor dental and oral hygiene lead to dental caries. D. Emesis from purging corrodes the tooth enamel.

Correct Answer is D

Explanation

a. Food is rapidly ingested without proper chewing: While this might happen in bulimia nervosa, it does not explain dental erosion.
b. Purging causes the depletion of dietary calcium: Calcium depletion could affect bones and teeth but is not the primary reason for the dental erosion seen in bulimia nervosa.
c. Poor dental and oral hygiene lead to dental caries: While poor hygiene can contribute to dental issues, the primary cause of dental deterioration in bulimia is the acid from vomiting.
d. Emesis from purging corrodes the tooth enamel. Frequent vomiting in bulimia nervosa exposes teeth to stomach acid, which erodes the enamel and leads to dental deterioration.
