The nurse is preparing a dose of 10 mg of teriparatide. The medication is labeled 760 mcg/2.4 mL. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["31.6"]
The correct answer is : 31.6 mL
Let’s calculate this step by step:
Step 1: Convert 10 mg of teriparatide to mcg. We know that 1 mg = 1000 mcg. So, 10 mg = 10 × 1000 mcg = 10000 mcg.
Step 2: The medication is labeled as 760 mcg/2.4 ml. This means that 760 mcg of the medication is present in 2.4 mL.
Step 3: Now, we need to find out how many ml will contain 10000 mcg of the medication. We can set up a proportion to solve this:
(760 mcg / 2.4 ml) = (10000 mcg / x mL)
Step 4: Solving for x, we cross-multiply and divide:
x ml = (10000 mcg × 2.4 ml) ÷ 760 mcg
Step 5: Calculate the result:
x ml = 24000 mcg·ml ÷ 760 mcg = 31.57894736842105 mL
Step 6: If rounding is required, round to the nearest tenth:
x ml = 31.6 mL
So, the nurse should administer 31.6 mL of the medication.

Correct Answer is C
Explanation
Choice A: 18%. This is not the correct percentage, as it only accounts for one lower extremity. According to the rule of nines, each lower extremity accounts for 9% of body surface area on both anterior and posterior sides, so both lower extremities would account for 18% x 2 = 36%.
Choice B: 27%. This is not the correct percentage, as it only accounts for one and a half lower extremities. According to the rule of nines, each lower extremity accounts for 9% of body surface area on both anterior and posterior sides, so one and a half lower extremities would account for 9% x 3 = 27%.
Choice C: 36%. This is the correct percentage, as it accounts for both lower extremities. According to the rule of nines, each lower extremity accounts for 9% of body surface area on both anterior and posterior sides, so both lower extremities would account for 9% x 4 = 36%.
Choice D: 45%. This is not the correct percentage, as it accounts for more than both lower extremities. According to the rule of nines, each lower extremity accounts for 9% of body surface area on both anterior and posterior sides, so more than both lower extremities would account for more than 9% x 4 = 36%.
Correct Answer is B
Explanation
Choice B is correct because initiating a continuous infusion of IV fluids per prescription has highest priority for an infant with pyloric stenosis who is scheduled for a pyloromyotomy. Pyloric stenosis causes projectile vomiting and dehydration, which can lead to metabolic alkalosis and electrolyte imbalance. The infant needs IV fluids to correct these abnormalities and prevent complications.
Choice A is incorrect because marking an outline of the “olive-shaped” mass in the right epigastric area is not a priority action for an infant with pyloric stenosis who is scheduled for a pyloromyotomy. The “olive-shaped” mass is a palpable sign of pyloric stenosis, but it does not require any intervention before surgery.
Choice C is incorrect because monitoring amount of intake and infant's response to feedings is not a priority action for an infant with pyloric stenosis who is scheduled for a pyloromyotomy. The infant may have difficulty feeding due to vomiting and gastric distension, which can worsen their dehydration and malnutrition. The infant may need to be kept NPO (nothing by mouth) before surgery.
Choice D is incorrect because instructing parents regarding care of the incisional area is not a priority action for an infant with pyloric stenosis who is scheduled for a pyloromyotomy. The incisional area will need proper care after surgery, but this can be taught later when the infant is stable and ready for discharge.
