Extract:
Question 1 of 5
A nurse is preparing to administer liquid famotidine 20 mg PO every 6 hr for GERD. Available is famotidine 40 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: The correct answer is A: 2.5 mL.
To determine this, first calculate the total daily dose needed (20 mg every 6 hr = 80 mg/day).
Then, calculate the amount of medication per mL (40 mg/5 mL = 8 mg/mL). Finally, divide the total daily dose by the amount of medication per mL to get the mL per dose (80 mg ÷ 8 mg/mL = 10 mL/day, 10 mL ÷ 4 doses = 2.5 mL). This ensures the correct dose is administered.
Choices B-G are incorrect as they do not follow the correct calculation process or do not result in the accurate dosage required.
Question 2 of 5
A nurse is preparing to administer hydrochlorothiazide 75 mg PO. The amount available is hydrochlorothiazide 50 mg/tablet. How many tablets should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies.)
Correct Answer: A
Rationale:
To calculate the number of tablets to administer, divide the desired dose by the dose strength per tablet. In this case, 75 mg ÷ 50 mg = 1.5 tablets. This means the nurse should administer 1.5 tablets of hydrochlorothiazide. Since the tablets cannot be divided, rounding to the nearest whole tablet is necessary, making the correct answer A: 1.5 tablet(s). Other choices are incorrect because they do not accurately reflect the calculation. B: 1.4 tablet(s), C: 1.6 tablet(s), and D: 1.7 tablet(s) do not match the calculated dose of 1.5 tablets.
Question 3 of 5
A nurse is collecting data from an infant who has otitis media. The nurse should expect which of the following findings?
Correct Answer: B
Rationale: The correct answer is B: Tugging on the affected ear lobe. In otitis media, infants may tug or rub the affected ear due to pain or discomfort. This behavior is a common sign of ear discomfort in infants. Erythema and edema of the affected auricle (choice
A) may be seen in external ear infections, not otitis media. Bluish-green discharge from the ear canal (choice
C) is not a typical finding in otitis media. An increase in appetite (choice
D) is not a common symptom of otitis media. Thus, choice B is the most appropriate finding in an infant with otitis media.
Question 4 of 5
A nurse is preparing to administer Dofetilide 200 mcg PO to a client. Available is Dofetilide 50 mcg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: The correct answer is A: 4 tabs.
To achieve a dose of 200 mcg, the nurse should administer 4 tablets of 50 mcg each (4 x 50 = 200 mcg). This calculation ensures the client receives the prescribed dose accurately. Other choices are incorrect because they do not add up to the required dose of 200 mcg: B (3 x 50 = 150 mcg), C (2 x 50 = 100 mcg), and D (1 x 50 = 50 mcg).
Therefore, administering 4 tablets is the correct and accurate dosage calculation in this scenario.
Question 5 of 5
A nurse is preparing a 4-year-old child for discharge following a bilateral myringotomy with tympanostomy tube placement. The mother asks what to do if the tubes fall out. The nurse should give the parent which of the following instructions?
Correct Answer: A
Rationale: The correct answer is A. It is important for the parent to call the health care clinic to report that the tubes have fallen out. This is because healthcare professionals need to assess the situation, determine if the tubes need to be replaced, and provide further instructions. Taking the child to an emergency department (
B) may not be necessary unless there are complications. Reassuring the mother that the tubes will not fall out (
C) is not accurate as tubes can indeed fall out. Gently reinserting the tubes (
D) should never be done by a parent as this can cause harm. It is crucial to involve the healthcare provider in managing the situation.
