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 D
Explanation
The correct answer is choice D, spotting.
Placenta previa is a condition where the placenta implants in the lower part of the uterus, partly or completely covering the cervical opening.
This can cause painless, bright red vaginal bleeding, usually in the third trimester.
Spotting is a sign of placenta previa and should be reported to the provider immediately.
Choice A is wrong because nausea is not a specific finding of placenta previa.
Nausea can occur in normal pregnancy or in other conditions such as hyperemesis gravidarum or preeclampsia.
Choice B is wrong because polyhydramnios is not a finding of placenta previa.
Polyhydramnios is a condition where there is too much amniotic fluid in the uterus, which can cause complications such as preterm labor, cord prolapse, or fetal malformations.
Choice C is wrong because uterine tenderness is not a finding of placenta previa.
Uterine tenderness is a sign of abruptio placentae, which is a condition where the placenta separates from the uterine wall before delivery.
This can cause severe abdominal pain, dark red vaginal bleeding, and fetal distress.
Correct Answer is ["C","D","E"]
Explanation
The correct answer is choice CDE.
Choice A rationale:
Eating fish for dinner at least twice per week is not specifically recommended for pancreatitis patients. A low-fat diet is generally advised, but the frequency of fish consumption is not a key point in discharge teaching.
Choice B rationale:
Limiting coffee intake is not a primary focus in pancreatitis discharge instructions. While caffeine can irritate the digestive system, the emphasis is more on avoiding alcohol and fatty foods.
Choice C rationale:
Eating small, frequent meals is recommended to avoid overloading the digestive system and to help manage symptoms of pancreatitis.
Choice D rationale:
Pale bowel movements can indicate a problem with bile flow, which is not a normal expectation for pancreatitis patients. This could suggest a complication that needs medical attention.
Choice E rationale:
Dark urine can be a sign of dehydration or liver issues, which should be reported to a healthcare provider as it may indicate a complication.
