A nurse is reinforcing teaching with a parent of a 4-month-old infant during a home visit.

Which of the following statements by the parent indicates an understanding of the teaching?

The correct answer is A.

Weight loss.

Furosemide is a loop diuretic that is used to treat fluid volume excess by increasing the excretion of water and electrolytes through the kidneys. Weight loss is an indication that the medication has been effective in reducing the excess fluid in the body.

Choice B is wrong because decreased inflammation is not a direct effect of furosemide.

Inflammation is a response to tissue injury or infection, and furosemide does not have any anti-inflammatory properties.

Choice C is wrong because increased blood pressure is not an indication of furosemide effectiveness.

Furosemide lowers blood pressure by reducing the preload and afterload on the heart.

Increased blood pressure may indicate that the dose of furosemide is insufficient or that there are other factors contributing to hypertension.

Choice D is wrong because decreased pain is not an expected outcome of furosemide therapy.

Furosemide does not have any analgesic effects, and pain may be caused by various conditions that are not related to fluid volume excess.

Normal ranges for weight, blood pressure and pain vary depending on the individual patient’s baseline and goals.

However, some general guidelines are:

• Weight: A weight loss of 0.5 to 1 kg per day is considered safe and effective for patients with fluid volume excess.
• Blood pressure: The target blood pressure for most patients with heart failure is less than 130/80 mmHg.
• Pain: The pain level should be assessed using a valid and reliable scale, such as the numeric rating scale or the visual analogue scale, and treated according to the patient’s preference and tolerance.

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.
