Question 3 of 5

The nurse is caring for a client following a myocardial infarction. Which of the following enzymes are specific to cardiac damage?

Question 4 of 5

The FHR pattern in a laboring client begins to show early decelerations. The nurse would best respond by:

Correct Answer: C

Rationale: Early decelerations are reassuring and do not warrant notification of the physician. Because early decelerations is a reassuring pattern, it would not be necessary to change the client's position. Early decelerations warrant the continuation of close FHR monitoring to distinguish them from more ominous signs. O2 is not warranted in this situation, but it is warranted in situations involving variable and/or late decelerations.

Question 5 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.
