Questions for Cardiovascular Assessment Questions
Question 1 of 5
In the emergency department, an older adult with hypertension is started on nitroprusside. After 1 hour of treatment, the MAP is 55 mm Hg. What nursing action is a priority?
Correct Answer: D
Rationale: Nitroprusside is a potent vasodilator medication. Lowering the blood pressure too rapidly may decrease cerebral, coronary, or renal perfusion.
Question 2 of 5
What is the nurse's priority action if a patient receiving digoxin has a heart rate of 58 bpm?

Question 5 of 5
A patient presents to the hospital with head trauma. He has an elevated sodium level and a large volume of dilute urine. He is found to have diabetes insipidus. Which is most true:
Correct Answer: A
Rationale: Head trauma can cause central diabetes insipidus (DI) by damaging the pituitary or hypothalamus, leading to reduced ADH and resulting in dilute urine and hypernatremia. This can be partial or complete, making A correct. DDAVP is effective only in central DI, not nephrogenic, and fluid restriction is inappropriate here.
