A nurse is reporting a client's laboratory tests to the provider to obtain a prescription for the client's daily warfarin. Which of the following laboratory tests should the nurse plan to report to obtain the prescription for the warfarin?

A. Correct. The child should be instructed to blow into the peak expiratory flow meter as hard and quickly as possible to achieve maximal effort. This provides an accurate measure of peak expiratory flow, which is important in assessing asthma control.
B. Incorrect. The child's body position during testing does not typically affect the accuracy of peak expiratory flow measurements.
C. Incorrect. While recording the average of multiple readings over time is important, the child needs to understand how to perform a single accurate reading first.
D. Incorrect. The tongue is not usually involved in the use of a peak expiratory flow meter.
The child should place their lips tightly around the mouthpiece to create a seal while blowing forcefully into the device.

A.Jogging or any form of vigorous exercise, especially high-impact activities, should generally be avoided for at least 4–6 weeks after retinal surgery. This is because high-impact activities can increase intraocular pressure and potentially disrupt the healing retina. Jogging involves bouncing or jolting movements, which could adversely affect the repair.

B. Bending at the waist places increased pressure on the eye and can disrupt the healing process after retinal surgery. This action increases intraocular pressure and is typically discouraged postoperatively.

C. Light lifting, such as lifting objects under 10 pounds, is typically allowed after several weeks of recovery, once the initial healing has occurred and the client is no longer at risk for increasing intraocular pressure or straining the surgical site.

D. While sewing itself is a low-impact activity, the act of sewing typically involves bending over or placing the head below the waist, which could still increase intraocular pressure. Early postoperative instructions often caution against activities that involve bending or straining the eyes, such as sewing, reading, or watching TV for extended periods.

D. Correct. After surgical repair of a detached retina, clients should avoid activities that might increase intraocular pressure, like heavy lifting or bending at the waist. Activities that do not strain the eye, like sewing, can typically be resumed earlier.
