The patient's blood pressure at 8:00 a.m. was 124/80 mm Hg, and now at 12:00 p.m., it is 152/94 mm Hg. The charge nurse appropriately instructs the newly hired nurse that
1. The patient's blood pressure should be rechecked in 15 minutes.
2. Any abnormal findings should be rechecked within 8 hours.
3. Because the blood pressure has become elevated, it should be rechecked in 1 to 2 hours.
4. There is no reason to recheck the blood pressure because this pattern of elevation is typical for this patient.
Question 2
A 75-year-old patient is breathing at a rate of 30 and denies dyspnea. The breath sounds are clear to auscultation in all five lobes.
The nurse will further assess the patient's respiratory and circulatory systems by checking capillary refill. A normal finding would be
1. Nail beds pink, capillary refill 6 seconds.
2. Nail beds cyanotic, capillary refill 4 seconds.
3. Nail beds pink, capillary refill 5 seconds.
4. Nail beds blanched, capillary refill 3 seconds.
