When measuring the blood pressure in each of the patient’s arms, the nurse recognizes that in the normal adult, the pressures a) differ no more than 5 mm Hg between arm pressures. Normally, in the absence of disease of the vasculature, there is a difference of no more than 5 mm Hg between arm pressures. b) must be equal in both arms. The pressures in each arm do not have to be equal in order to be considered normal. c) may vary 10 mm Hg or more between arms. Pressures that vary more than 10 mm Hg between arms indicate an abnormal finding. d) may vary, with the higher pressure found in the left arm. The left arm pressure is not anticipated to be higher than the right as a normal anatomical variant.

When assessing the older adult, the nurse anticipates increase in which of the follow components of respiratory status? a) Residual lung volume As a result, patient experience fatigue and breathlessness with sustained activity. b) Vital capacity The nurse anticipates decreased vital capacity. c) Gas exchange and diffusing capacity The nurse anticipates decreased gas exchange and diffusing capacity resulting in impaired healing of tissues due to decreased oxygenation. d) Cough efficiency The nurse anticipates difficulty coughing up secretions due to decreased cough efficiency.
