A nurse is instructing a school-age child who has asthma about the use of a peak expiratory flow meter.
Which of the following instructions should the nurse include in the teaching?
Maintain a semi-Fowler’s position during testing
Place tongue on the mouthpiece of the meter
Blow into the meter as hard and quickly as possible
Record the average of the readings
The Correct Answer is C
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.

Correct Answer is A
Explanation
When updating protocols for the use of belt restraints, the nurse manager should include the following guideline:
A) Document the client’s condition every 15 min
Frequent documentation of the client's condition and the need for restraint is essential to monitor their well-being and ensure that restraints are used only when necessary. The other options are not recommended:
B) Requesting a PRN restraint prescription for clients who are aggressive is not appropriate because restraints should only be used when there is an immediate risk to the patient or others, and obtaining a PRN prescription for restraints is generally not standard practice.
C) Attaching the restraint to the bed's side rails is not recommended because restraints should be used as a last resort, and there are specific guidelines for restraint application to ensure patient safety.
D) Removing the client's restraint every is not appropriate either. Restraints should only be removed when the client's condition improves, and alternatives to restraint have been explored, or when it's deemed necessary for the patient's safety and well-being following established protocols and guidelines. The option seems incomplete and does not specify the appropriate time frame for removal.
Correct Answer is A
Explanation
The correct answer is choice A. Instruct the client to avoid coughing during the procedure.
A thoracentesis is a procedure that involves inserting a needle into the pleural space to remove excess fluid or air. Coughing can increase the risk of pneumothorax (collapsed lung) or bleeding during the procedure.
Choice B is wrong because the client does not need to be NPO (nothing by mouth) for 6 hr prior to the procedure. There is no risk of aspiration during a thoracentesis.
Choice C is wrong because the client should be positioned on the unaffected side for 4 hr following the procedure. This allows the affected lung to re-expand and prevents fluid from accumulating in the pleural space again.
Choice D is wrong because the client should not be placed in the prone position during the procedure. The prone position makes it difficult to access the pleural space and can compromise breathing.
