Extract:
Question 1 of 5
The nurse is caring for a client following a myocardial infarction. Which of the following enzymes are specific to cardiac damage?
Correct Answer: C
Rationale: CK-MB and LDH are specific to cardiac damage, with CK-MB being highly specific for myocardial infarction due to its presence in heart muscle.
Question 2 of 5
A 45-year-old client diagnosed with major depression is scheduled for electroconvulsive therapy (ECT) in the morning. Which of the following medications are routinely administered either before or during ECT?
Correct Answer: B
Rationale: Thioridazine (an antipsychotic drug), lithium (an antimanic drug), and benztropine (an antiparkinsonism agent) are generally administered to treat schizophrenic and bipolar disorders. Atropine (a cholinergic blocker), sodium brevitol (a short-acting anesthetic), and succinylcholine (a neuromuscular blocker) are administered either before or during ECT to counteract bradycardia and to provide anesthesia and total muscle relaxation. These are electrolyte substances administered to correct fluid and electrolyte imbalances in the body. Carbamazepine (an anticonvulsant), haloperidol (an antipsychotic), and trihexyphenidyl (an antiparkinsonism agent) are usually administered in psychiatric settings to control problems associated with psychotic behavior.

Correct Answer: A
Rationale: Hypothyroidism slows metabolism, leading to weight gain, fatigue, and other symptoms like cold intolerance and constipation.
Question 4 of 5
A client with schizophrenia is started on Zyprexa (olanzapine). Three weeks later, the client develops severe muscle rigidity and elevated temperature. The nurse should give priority to:
Correct Answer: D
Rationale: Muscle rigidity and fever suggest neuroleptic malignant syndrome (NMS), a life-threatening reaction to olanzapine. Immediate transfer to a medical unit for urgent treatment is critical.

Correct Answer: B
Rationale: Risperidone, an antipsychotic, is used to control acute manic symptoms like agitation, while lithium stabilizes mood over time, addressing the immediate behavioral excitement.
