A nurse is preparing to administer levothyroxine 0.75 mg PO once a day. The amount available is levothyroxine 88 mcg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["9"]
Step 1: Convert the dosage from mg to mcg. 0.75 mg × 1000 = 750 mcg Result: 750 mcg
Step 2: Determine the number of tablets needed. 750 mcg ÷ 88 mcg/tablet = 8.5227 tablets Result: 8.5227 tablets
Step 3: Round the result to the nearest whole number. 8.5227 tablets rounded to the nearest whole number = 9 tablets Result: 9 tablets
The nurse should administer 9 tablets per dose.

Correct Answer is D
Explanation
A: Degenerative joint changes can affect mobility and overall health but do not directly contribute to aspiration pneumonia.
B: Decreased gastric secretions can affect digestion but are not a primary factor in the development of aspiration pneumonia.
C: A decreased sense of smell can affect appetite and food intake but does not directly lead to aspiration pneumonia.
D: A diminished cough reflex is a significant age-related change that can contribute to the development of aspiration pneumonia. The cough reflex helps clear the airway of food, liquid, and other foreign materials. When this reflex is diminished, the risk of aspiration and subsequent pneumonia increases.
Correct Answer is B
Explanation
A: Pulling the auricle upward and outward is the correct technique for adults and children over 3 years old, not for a 2-year-old child.
B: Pulling the auricle down and back is the correct technique for straightening the ear canal in children under 3 years old. This allows for proper administration of the eardrops.
C: Sitting the child up to insert a cotton ball into the innermost ear canal is not appropriate. Cotton balls should not be inserted deeply into the ear canal.
D: Sitting the child up for 2 to 3 minutes after instilling drops is not necessary. The child should remain in a position that allows the drops to stay in the ear canal for the prescribed time.
