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 B
Explanation
Choice A reason:
Explaining the procedure to the client before verifying informed consent is not an appropriate action: While it is essential to explain the procedure to the client and ensure they have a clear understanding of what they are consenting to, this step typically occurs before the informed consent form is presented. The purpose of the informed consent form is to document that the client has received adequate information and has given their consent voluntarily
Choice B reason:
Confirming the client's signature is authentic is the correct action. Verifying the record of informed consent for a client scheduled for surgery involves several important steps. Of these, the nurse's primary responsibility is to ensure that the client's signature on the informed consent form is authentic. This means ensuring that the client themselves or their authorized representative has signed the form willingly and without coercion.
Choice C reason:
Providing information on the informed consent form about the benefits of the surgery is not an appropriate action: The informed consent form typically contains information about the procedure, its risks, possible complications, and alternatives, but it is not the nurse's responsibility to provide this information. The healthcare provider or surgeon is responsible for explaining the details of the surgery to the client before obtaining their consent.
Choice D reason:
Informing the client about the condition that requires treatment is not an appropriate action: The responsibility of informing the client about their medical condition, the need for treatment, and the available options lies with the healthcare provider or surgeon, not the nurse. The nurse may assist in providing information or answering questions, but the primary responsibility for discussing the medical condition lies with the provider.
Correct Answer is B
Explanation
Choice A reason:
Completing an incident report is not the correct action. An incident report should be completed as part of the hospital's protocol to document the medication error and ensure appropriate follow-up and investigation.
Choice B reason:
Checking the client for indications of bleeding is the correct action to be taken. In this situation, the nurse's first priority should be to assess the client for indications of bleeding, as the client received a significantly higher dose of IV heparin than prescribed. Heparin is an anticoagulant medication used to prevent blood clots, and an overdose can increase the risk of bleeding.
After administering the wrong dose of medication, the nurse's immediate concern is the client's safety and well-being. Checking for signs of bleeding, such as petechiae, ecchymosis, hematomas, bleeding gums, melena (black, tarry stools), haematuria (blood in urine), or any other unusual bleeding, is crucial.
Choice C reason:
Monitor the client's aPTT levels: This is not the correct action to be taken. Monitoring the client's activated partial thromboplastin time (aPTT) levels is essential to assess the client's coagulation status and determine if the overdose of heparin has affected their clotting ability. The healthcare provider may adjust the heparin dosage based on the aPTT levels.
Choice D reason:
Notify the risk manager: This is not the correct action to be taken. The risk manager or appropriate supervisor should be informed about the medication error as soon as possible to initiate a thorough review of the incident and take necessary steps to prevent similar errors in the future.
