Answer to Question 1
A
Exercise is instrumental in the reduction of systolic and diastolic blood pressure readings. Low- to moderate-intensity aerobic exercise such as brisk walking and bicycling appear to be the most effective in lowering blood pressure.
Weight training and high-intensity aerobics seem to have minimal benefits in lowering blood pressure.
Isometric exercises involve tightening or tensing of muscles without moving body parts. Isomet-ric exercise is not appropriate to help lower blood pressure.
Range-of-motion exercises improve the client's joint mobility. This is not the best type of exercise to help lower blood pressure.
Answer to Question 2
D
Feedback
A Normally during the immediate recovery phase in the PACU, faint or absent bowel sounds are auscultated in all four quadrants. Patients who have had abdominal surgery may develop paralytic ileus, with a return of bowel sounds 24 to 48 hours later.
B The acute incisional pain experienced in this stage of recovery is usually not relieved with noninvasive comfort measures but will abate with pharmacological measures of pain relief.
C Depending on the surgery, a patient may not regain voluntary control over urinary function for six to eight hours after anaesthesia.
D In the PACU, the patient is often drowsy. The effects of anaesthetic agents subdue the patient's level of consciousness and neurological function.
