All of the following statements concerning captopril are correct EXCEPT:
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A client receives a diagnosis of bipolar I disorder, current episode depressed. A physician prescribes paroxetine (Paxilâ) for the client. The client is encouraged to participate in unit activities and to talk about her feelings. Despite all efforts, the client's depression becomes profound. The client is in total despair and is in a vegetative state. The physician obtains consent to perform electroconvulsive therapy (ECT). What is the rationale behind this treatment for profound depression?
Correct Answer: D
Rationale: The correct answer is D because electroconvulsive therapy (ECT) is thought to increase levels of norepinephrine and serotonin, which are neurotransmitters involved in regulating mood. By increasing these neurotransmitters, ECT can help elevate mood and alleviate symptoms of depression. This rationale is supported by research and clinical evidence showing the effectiveness of ECT in treating severe depression. Choices A and C are incorrect because ECT does not work by making the client forget painful memories or by satisfying any perceived need for punishment. Choice B is incorrect because ECT does not stimulate the central nervous system in the same way as CNS stimulant medications. ECT works through different mechanisms involving changes in brain chemistry rather than direct CNS stimulation.
Question 3 of 5
A patient's serum lithium level is reported as 1.9 mEq/L. The nurse should immediately:
Correct Answer: B
Rationale: The correct answer is B: Assess for signs and symptoms of toxicity. A serum lithium level of 1.9 mEq/L is above the therapeutic range (0.6-1.2 mEq/L) and could indicate lithium toxicity. The nurse should assess the patient for signs such as vomiting, diarrhea, tremors, confusion, and drowsiness. Prompt assessment is crucial to prevent serious complications. Restricting sodium and fluid intake (choice A) may be necessary in some cases, but the priority is to assess for toxicity first. Seeking ICU transfer (choice C) is premature without assessing the patient first. Notifying the physician (choice D) should be done after assessing the patient for toxicity.
Question 4 of 5
The nurse is assessing a patient for possible evidence of digitalis toxicity. Which of these is included in the signs and symptoms for digitalis toxicity?
Correct Answer: D
Rationale: The correct answer is D because a low apical pulse rate (bradycardia) with an irregular rhythm is a classic sign of digitalis toxicity due to its effect on the heart's conduction system. Digitalis can cause bradycardia and various conduction disturbances. Choices A, B, and C do not specifically reflect the characteristic bradycardia seen in digitalis toxicity.
Question 5 of 5
The parent of an adolescent with schizophrenia asks the nurse, “My child’s doctor ordered a PET. What kind of test is that?” Select the nurse’s best reply.
Correct Answer: B
Rationale: The correct answer is B because it provides an accurate and detailed explanation of what a PET scan is. Positron-emission tomography involves injecting a radioactive substance into the body to show blood flow and brain activity. This is crucial in diagnosing conditions like schizophrenia. Choice A is incorrect as it inaccurately describes a PET scan as similar to an MRI, which does not involve radioactive substances. Choice C is incorrect as a PET scan does not use X-rays to provide images. Choice D is incorrect as a PET scan does not measure electrical activity with scalp electrodes but rather shows blood flow and brain activity.
