A nurse in an emergency department is reviewing the medical record of a client who is having an acute myocardial infarction.

Which of the following findings places the client at risk if he receives alteplase?

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.

Fish is a good source of protein and omega-3 fatty acids, which can help lower blood pressure, reduce inflammation, and prevent blood clots. Fish is also low in sodium, which is important for people with hypertension, as excess sodium can raise blood pressure by retaining fluid in the body. Fish is part of the DASH diet, which stands for Dietary Approaches to Stop Hypertension, and is a healthy eating plan that emphasizes fruits, vegetables, whole grains, low-fat dairy, nuts, seeds, legumes, and lean meats.

Choice A. Cheese is wrong because cheese is high in sodium and saturated fat, which can increase blood pressure and cholesterol levels.
Cheese should be limited or avoided by people with hypertension.

Choice C. Red meat is wrong because red meat is also high in sodium and saturated fat, as well as cholesterol, which can contribute to hypertension and heart disease.
Red meat should be eaten sparingly or replaced by leaner sources of protein like fish, poultry, or beans.

Choice D. Canned black beans are wrong because canned black beans are high in sodium, as most canned foods are preserved with salt. Canned black beans should be rinsed well before eating or replaced by dried or cooked black beans, which are lower in sodium and high in fiber, potassium, magnesium, and calcium, which are beneficial for blood pressure control.
