A child who weighs 25 kg is receiving IV ampicillin at a dose of 300 mg/kg/24 hours in equally divided doses every 4 hours. How many milligrams should the nurse administer to the child for each dose?

Correct Answer: A

Rationale: To calculate the correct dose for each administration, you first need to find the total daily dose: 300 mg/kg * 25 kg = 7500 mg/day. Since this total dose is divided into equally divided doses every 4 hours, there are 6 doses in 24 hours. Therefore, 7500 mg · 6 doses = 1250 mg per dose. The nurse should administer 1250 mg every 4 hours, resulting in a total of 1875 mg for each dose in a 24-hour period. Choice A, 1875 mg, is the correct answer. Choice B, 625 mg, is incorrect as it does not consider the total daily dose and the frequency of administration. Choice C, 2000 mg, is incorrect as it is not the calculated dosage based on the given parameters. Choice D, 1500 mg, is also incorrect as it does not reflect the correct dosage calculation for each dose.

Correct Answer: D

Rationale: The correct answer is D. Wearing long sleeves and pants helps prevent tick bites, which can transmit Lyme disease. Ticks carrying Lyme disease are often found in wooded or grassy areas, so covering exposed skin can reduce the risk of being bitten by an infected tick. Choices A, B, and C do not address the specific mode of transmission of Lyme disease through tick bites, making them incorrect.

Correct Answer: C

Rationale: In pediatric basic life support, for an unresponsive infant who is not breathing normally, the correct action is to give two breaths that make the chest rise. This helps provide oxygen to the infant's body and is a crucial step in resuscitation efforts for infants in distress. Choices A, B, and D are incorrect. Palpating the femoral pulse or feeling the carotid pulse is not indicated in this scenario where the infant is unresponsive and not breathing. Delivering cycles of chest compressions and breaths is not the immediate action to take; the priority is to provide two breaths to help with oxygenation.

Correct Answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario. The nurse obtained an apical heart rate of 128 bpm, which is within the expected range for a 2-year-old child. Therefore, there is no immediate concern to withhold the scheduled dose of digoxin. Determining the pulse deficit is not necessary as the heart rate is appropriate. Calculating the safe dose range is not needed as the current dose is within the therapeutic range. Reviewing the serum digoxin level may be indicated later for monitoring but is not urgent based on the heart rate assessment. Administering the scheduled dose of digoxin is the correct action at this time.

Correct Answer: A

Rationale: When dealing with seborrheic dermatitis (cradle cap) in infants, it is essential to use a soft brush and gently scrub the affected area to help remove the scales. This process can aid in managing the condition and preventing further build-up. It is important to be gentle to avoid irritating the baby's delicate skin. Choice B is incorrect as gentle scrubbing with a soft brush can help in the removal of scales. Choice C is incorrect because regular but gentle washing is recommended to manage cradle cap. Choice D is incorrect as using specialized shampoos designed for cradle cap is usually recommended over soap and water.
