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?

A.

Maintain a semi-Fowler’s position during testing

B.

Place tongue on the mouthpiece of the meter

C.

Blow into the meter as hard and quickly as possible

D.

Record the average of the readings

Answer and Explanation

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 C

Explanation

Choice A reason:

Administer epinephrine subcutaneously. This is not the necessary action to be taken. Epinephrine is used to treat severe allergic reactions (anaphylaxis). However, in this case, the client is experiencing a febrile non-haemolytic transfusion reaction, not an allergic reaction.

Choice B reason:

Place the blood bag in a biohazard bag before discarding. This is not the necessary action to be taken by the nurse. Proper disposal of biohazardous materials is essential, but in this situation, the nurse's priority is to address the client's condition and not the disposal of the blood bag

Choice C reason:

Documentation of the transfusion reaction is crucial for the client's medical history and for future reference. The nurse should record the client's signs and symptoms, the actions taken, and any other relevant information related to the reaction.

Choice D reason

Infuse 500 ml lactated Ringer's IV. This is not necessary action to be taken by the nurse because there is no indication for infusing lactated Ringer's solution in response to the transfusion reaction described. Treatment for febrile non-haemolytic transfusion reactions generally involves stopping the transfusion, administering antipyretics (like acetaminophen) if necessary, and providing supportive care as needed.

Correct Answer is ["B","C","D","E","F"]

Explanation

Answer is B, C, D, E, F. These are the findings that suggest possible elder abuse or neglect.

  • B: Client’s report of lack of food in home. This may indicate neglect by the adult child who is supposed to provide adequate nutrition for the client.
  • C: Client’s report of lack of access to bank accounts. This may indicate financial abuse by the adult child who is controlling the client’s money without his permission.
  • D: Client’s avoidance of eye contact. This may indicate emotional abuse by the adult child who is intimidating or threatening the client.
  • E: Client’s report of weight loss. This may indicate neglect by the adult child who is not meeting the client’s basic needs or physical abuse by the adult child who is causing bodily harm to the client.
  • F: Numerous bruises in various stages of healing. This may indicate physical abuse by the adult child who is hitting or injuring the client.

A: ECG results. This is not a finding that suggests elder abuse or neglect. It is a diagnostic test that measures the electrical activity of the heart and can help detect cardiac problems. It does not provide information about the client’s social or emotional well-being.

Normal ranges for vital signs:.

  • Temperature: 36.1°C to 37.2°C (97°F to 99°F).
  • Heart rate: 60 to 100 beats per minute.
  • Blood pressure: less than 120/80 mm Hg.
  • Respiratory rate: 12 to 20 breaths per minute.
  • SpO2: 95% to 100% on room air. Table for BMI categories:

BMI

Weight Status

Below 18.5

Underweight

18.5 to 24.9

Normal

25.0 to 29.9
