Question 1 of 5
The client states she does not understand what causes idiopathic thrombocytopenic purpura (ITP). The nurse provides which of the following explanations?
Correct Answer: A
Rationale: Idiopathic thrombocytopenic purpura (ITP) is an autoimmune condition where antibodies coat platelets, marking them for destruction by the spleen. This leads to a low platelet count. The liver is not primarily involved, ITP is not due to an underactive immune system, and while 'idiopathic' means the exact trigger is unknown, the autoimmune mechanism is well-established.

A postmenopausal client is scheduled for a bone-density scan. To plan for the client's test, what should the nurse communicate to the client?

Which intervention promotes comfort post-cystectomy?

The client is receiving an I.V. infusion of 5% dextrose in water (D5W) and oxygen at 2 L/minute. The nurse's first course of action should be:
Correct Answer: B
Rationale: Frequent PVCs (eight per minute) may indicate irritability of the myocardium, risking serious arrhythmias. Notifying the physician promptly ensures timely intervention, such as antiarrhythmic therapy.
