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 C
Explanation
A: Hypertension is not typically a late sign of hypoxemia. It can occur in various conditions but is not specific to hypoxemia.
B: Tachycardia is an early sign of hypoxemia as the body attempts to compensate for low oxygen levels by increasing the heart rate.
C: Pallor is a late sign of hypoxemia. It indicates poor oxygenation and perfusion, often seen when the body can no longer compensate for the lack of oxygen.
D: Bradypnea, or slow breathing, is not a typical sign of hypoxemia. Hypoxemia usually causes an increase in respiratory rate (tachypnea) as the body tries to take in more oxygen.
Correct Answer is A
Explanation
A: The passage of flatus is a clear indication that intestinal function is returning. It shows that the gastrointestinal tract is beginning to move gas through the intestines, which is a positive sign of recovery after abdominal surgery.
B: A request for a cup of tea and some toast indicates that the client is feeling better and has an appetite, but it does not specifically indicate the return of intestinal function.
C: Hypoactive bowel sounds in two quadrants suggest reduced intestinal activity, which is not a sign of returning intestinal function. Normal bowel sounds should be present in all quadrants.
D: Abdominal distention can indicate a buildup of gas or fluid in the intestines, which is not a sign of returning intestinal function. It may suggest an obstruction or other complications.
