A nurse is preparing to administer levothyroxine 50 mcg to a client. Available is levothyroxine 0.025 mg/tablet. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["2"]
Desired dose = 50 mcg
Available strength = 0.025 mg/tablet
- Convert desired dose to milligrams (mg):
1 mg = 1000 mcg
50 mcg / 1000 mcg/mg = 0.05 mg
- Calculate the number of tablets:
Number of tablets = Desired dose (mg) / Available strength (mg/tablet)
= 0.05 mg / 0.025 mg/tablet
= 2 tablets

Correct Answer is D
Explanation
A. "You can add honey to sweeten vegetables if they do not like them." Honey should be avoided in infants under 12 months due to the risk of infant botulism, a serious and potentially fatal illness caused by Clostridium botulinum spores.
B. "Raw carrots are a good snack to provide and can help with teething." Raw carrots pose a choking hazard for infants and should not be given in solid form. Teething rings or soft, age-appropriate snacks are safer alternatives for teething relief.
C. "You can mash canned vegetables instead of purchasing baby food." Canned vegetables often contain added sodium, which is not recommended for infants. Fresh or frozen vegetables without added salt are a safer option when preparing homemade baby food.
D. "Introduce one new food every 3 to 5 days when starting solid foods." This approach allows the caregiver to monitor for allergic reactions or food sensitivities. Introducing foods gradually helps identify the cause of any adverse response and promotes safe dietary progression.
Correct Answer is B
Explanation
A. "Morphine 3.0 mg sub q every 4 hr PRN for pain." Including a trailing zero (3.0 mg) is considered unsafe and is discouraged in medication documentation. It increases the risk of a tenfold overdose if the decimal is missed.
B. "Morphine 3 mg subcutaneous every 4 hr PRN for pain." This entry uses the correct dosage format without a trailing zero, the full term "subcutaneous" instead of abbreviations, and proper medical terminology. It adheres to safe documentation practices as per The Joint Commission guidelines.
C. "Morphine 3 mg SC q 4 hr PRN for pain." The abbreviation “SC” is considered unsafe and prone to misinterpretation. Also, "q" for "every" is discouraged in clinical documentation due to potential misreading and error.
D. "Morphine 3 mg SQ every 4 hr PRN for pain." The abbreviation “SQ” can be misinterpreted or mistaken for “5 every” or other terms. Safe practice requires spelling out “subcutaneous” to prevent errors in medication administration.
