A medical assistant is preparing a patient for a spirometry test. The assistant should remind the patient that which of the following could affect the test result?
Taking aspirin within 12 hr of testing
Using sedatives within 1 hr of testing
Exercising 2 hr prior to testing
Eating a heavy meal 4 hr prior to testing
The Correct Answer is C
A. Taking aspirin within 12 hr of testing: Aspirin does not generally affect spirometry results.
B. Using sedatives within 1 hr of testing: Sedatives may affect respiratory function, but they are not a common consideration for spirometry preparation.
C. Exercising 2 hr prior to testing: Exercise can affect lung function temporarily, so it’s best to avoid vigorous exercise before a spirometry test.
D. Eating a heavy meal 4 hr prior to testing: While eating a heavy meal might cause some discomfort, it is less likely to affect the spirometry results significantly compared to exercise.

Correct Answer is A
Explanation
A. Irrigate the wound with sterile normal saline. Irrigating the wound with sterile normal saline is the appropriate action for cleaning a contaminated wound, as it helps to remove debris and reduce the risk of infection.
B. Insert liquid bandage into the wound. A liquid bandage is not appropriate for a contaminated wound, especially if the wound is jagged, as it could trap contaminants inside.
C. Wash the wound with soap and warm water. While soap and water are good for general wound cleaning, sterile normal saline is preferred for contaminated wounds in a clinical setting to minimize irritation and infection.
D. Apply microporous tape to the wound. Microporous tape is used for securing dressings, not for cleaning wounds.
Correct Answer is C
Explanation
A. Apply the patch with sterile gloves. Sterile gloves are not required when applying a transdermal patch; clean, non-sterile gloves are sufficient to avoid contamination.
B. Apply the new patch in the same location as the old one. Transdermal patches should be rotated to different sites to avoid skin irritation, so applying the new patch in the same location is not recommended.
C. Write the date and time on the patch with each application. Writing the date and time on the patch is essential for tracking when the patch was applied and when it needs to be changed, making this the correct action.
D. Reinforce damaged patches with adhesive tape. Damaged patches should not be reinforced with tape, as this could alter the drug's delivery. Instead, the patch should be replaced.
