ASTHMA/COPD QUIZ AND ANSWERS WITH COMPLETE
SOLUTIONS VERIFIED
When admitting a patient with a diagnosis of asthma exacerbation, the nurse will
assess for what potential triggers? Select all that apply.
Exercise
Allergies
Emotional stress
Decreased humidity
Upper respiratory infections
A, B, C, E
Although the exact mechanism of asthma is unknown, there are several triggers that
may precipitate an attack. These include allergens, exercise, air pollutants, upper
respiratory infections, drug and food additives, psychologic factors, and
gastroesophageal reflux disease (GERD). Decreased humidity is not a trigger.
,The patient is receiving 3 L of oxygen (O 2) via nasal cannula. Which action by the
nurse is most appropriate? Select all that apply.
Assesses eyes for dryness
Realizes that humidification is never needed
Adjusts humidification according to patient comfort
Assesses the bubble-through humidifier if humidity is used
Assures that the patient is wearing the nasal cannula correctly
C, D, E
Assessing the bubble-through humidifier if humidity is used, assuring that the patient is
wearing the nasal cannula correctly, and adjusting humidification according to patient
comfort are correct because oxygen (O 2) obtained from cylinders or wall systems is
dry. Dry O 2 has an irritating effect on mucous membranes and dries secretions. A
common device used for humidification when the patient has a cannula or a mask is a
bubble-through humidifier. It is important for the nurse to assess the bubble-through
humidifier if humidity is used to make sure the humidification is on. This adds to the
comfort of the patient. The nurse assesses the patient to make sure the nasal cannula
is worn correctly for optimal effect. The cannula can become easily dislodged.
, Humidification is adjusted according to the patient's comfort level. When oxygen levels
are 1 to 4 L, the use of humidification may not be the preference of all patients.
Believing that humidification is never needed is incorrect because the use of
humidification is a patient preference. The nurse should assess the patient's nose for
dryness, not the eyes.
The nurse is evaluating if a patient understands how to determine safely whether
a metered dose inhaler (MDI) is empty. The nurse interprets that the patient
understands this important information to prevent medication underdosing when
the patient describes which method to check the inhaler?
Place it in water to see if it floats.
Keep track of the number of inhalations used.
Shake the canister while holding it next to the ear.
Check the indicator line on the side of the canister.
B
The best method to determine when to replace an inhaler is by knowing the maximum
puffs available per MDI and then replacing it after the number of days when those
inhalations have been used (100 puffs/2 puffs each day = 50 days). It is no longer
appropriate to see if a canister floats in water or not because this is not an accurate way
