A nurse is caring for a child who has cystic fibrosis and requires postural drainage.

Which of the following actions should the nurse take?

The correct answer is choice B. Wear clean cotton socks every day.

This is because cotton socks can help keep the feet dry and prevent infections. Wearing clean socks every day can also prevent blisters and injuries from friction.

Choice A is wrong because soaking feet twice daily can make the skin too soft and prone to injury. It can also wash away natural oils that protect the skin.

Choice C is wrong because rounding the edges of toenails when trimming can cause ingrown nails, which can lead to infection and pain. Toenails should be trimmed straight across and filed smooth.

Choice D is wrong because using moisturizing lotion between the toes can create a moist environment that promotes fungal growth. Moisturizing lotion should be applied to the rest of the feet, but not between the toes.

Some other foot care guidelines for people with diabetes are:

• Inspect your feet daily and look for signs of injury, such as scrapes, cuts, blisters, etc.
• Wash your feet every day in warm water with mild soap.

Hot water and harsh soaps can damage your skin. Check the water temperature with your fingers or elbow before putting your feet in.

• Don’t walk barefoot.

Protect your feet from heat and cold. Wear appropriate fitting shoes to avoid injury and blisters.

• See a doctor to remove corns or calluses (don’t do it yourself). Don’t use chemical wart removers, razor blades, corn plasters, or liquid corn or callus removers.
• Don’t sit with your legs crossed or stand in one position for long periods of time.
• See your doctor regularly for foot exams and report any problems or changes in your feet.

The correct answer is choice C. Blow into the meter as hard and quickly as possible.

This is because a peak flow meter measures how fast you can push air out of your lungs when you blow out as hard and as fast as you can.

This is called peak expiratory flow rate (PEFR) or peak expiratory flow (PEF). It shows how open the airways are in the lungs and can help detect early signs of worsening asthma.

Choice A is wrong because maintaining a semi-Fowler’s position during testing is not necessary. You can sit or stand up straight, but make sure you do it the same way each time.

Choice B is wrong because placing tongue on the mouthpiece of the meter can block the air flow and affect the accuracy of the measurement. You should close your lips tightly on the mouthpiece instead.

Choice D is wrong because recording the average of the readings is not recommended.

You should record the highest of the three readings on a sheet of paper, calendar or in your asthma diary. This is your daily peak flow.

Normal ranges for peak flow vary depending on age, height, gender and race. You can use a chart or calculator to find out your predicted normal peak flow based on these factors. However, it is more important to find out your personal best peak flow by performing peak flow testing twice a day for two weeks when your asthma is under good control. Your personal best peak flow will be used to create your asthma action plan with your healthcare provider.
