A nurse is planning teaching for a client and their family about home oxygen therapy. Which of the following information should the nurse plan to include in the teaching?
Use synthetic fabrics for the client’s bedding
Apply petroleum jelly to soothe the mucous membranes
Clean the equipment with an alcohol-based cleaning product
Avoid using nail polish remover around the client
The Correct Answer is D
The correct answer is choice D. Avoid using nail polish remover around the client. Nail polish remover contains acetone, which is a flammable substance that can ignite in the presence of oxygen.
Using nail polish remover around the client can increase the risk of fire and burn injuries.
Choice A is wrong because synthetic fabrics can generate static electricity, which can also cause sparks and ignite oxygen.
The client’s bedding should be made of cotton or wool, which are natural fabrics that do not produce static electricity.
Choice B is wrong because petroleum jelly is a petroleum-based product that can react with oxygen and cause skin irritation or burns.
The client should use water-based moisturizers to soothe the mucous membranes.
Choice C is wrong because alcohol-based cleaning products are also flammable and can cause fires or explosions when exposed to oxygen.
The client should use mild soap and water to clean the equipment, and follow the manufacturer’s instructions for maintenance.
Some general safety tips for home oxygen therapy are:
- Keep away from heat and flame, such as candles, matches, lighters, stoves, fireplaces, etc.
- Do not smoke or allow others to smoke near the oxygen source
- Do not use aerosols, vapor rubs, oils, or other products that contain flammable substances near the oxygen source
- Store oxygen tanks or cylinders in a well-ventilated area away from direct sunlight and heat sources
- Secure oxygen tanks or cylinders to prevent them from falling or rolling
- Use the exact rate of oxygen prescribed by the doctor for each activity
- Check the oxygen gauge or level regularly and call the medical supply company when it is low
- Use a humidifier bottle if prescribed by the doctor to prevent dryness of the mucous membranes
- Change the nasal cannula, mask, and tubing as instructed by the medical supply company to prevent

Correct Answer is C
Explanation
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
The correct answer is B. Hip arthroplasty 1 week ago.
Alteplase is a drug that dissolves blood clots by converting plasminogen to plasmin. It can be used for acute ischemic stroke, but it has some contraindications that depend on the indication and the type of administration of the drug. Some common contraindications for alteplase are hypersensitivity, active internal bleeding, history of intracranial hemorrhage, bleeding disorders, and high blood pressure. Other contraindications may vary depending on the specific condition and the time window of treatment. Alteplase can cause serious or fatal bleeding as a side effect.
Choice A is wrong because family history of malignant hypertension is not an absolute contraindication for alteplase, although uncontrolled hypertension (>185 mmHg SBP or >110 mmHg DBP) is.
Choice C is wrong because chronic obstructive pulmonary disease is not a contraindication for alteplase, although it may increase the risk of pulmonary hemorrhage.
Choice D is wrong because acute renal failure 6 months ago is not a contraindication for alteplase, although current use of direct thrombin inhibitors or direct factor Xa inhibitors is.
Normal ranges for blood pressure are <120/80 mmHg for normal, 120-129/<80 mmHg for elevated, 130-139/80-89 mmHg for stage 1 hypertension, and ≥140/≥90 mmHg for stage 2 hypertension.
Normal ranges for platelet count are 150,000 to 450,000 platelets per microliter of blood.
Normal ranges for INR are 0.8 to 1.2 for people who are not taking blood thinners and 2 to 3 for people who are taking warfarin.
Normal ranges for aPTT are 25 to 35 seconds for people who are not taking blood thinners and 46 to 70 seconds for people who are taking heparin.
