Answer to Question 1
A
With a PCA system, the client controls medication delivery.
The PCA system is designed to deliver no more than a specified number of doses. The client does not choose the dosage.
The physician prescribes the type of medication to be used. The advantage for the client is that he or she may self-administer opioids with minimal risk of overdose.
The client does not control the route for administration. Systemic PCA typically involves IV drug administration, but can also be given subcutaneously.
Answer to Question 2
C
Symptoms of heart disease can include chest pain, palpitations, fatigue, cough, dyspnea, leg cramps, edema of extremities, fainting, and orthopnea.
Headache, dizziness, and tingling of body parts are more likely associated with a neurological problem, not vascular disease.
Diplopia, floaters, and headaches are indicative of an eye problem, not vascular disease.
Pain and cramping in the lower extremities are usually worsened with activity in vascular disease.
