Nursing Elites

1. A 2-year-old child with heart failure (HF) is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?

• A. Determine the pulse deficit.
• B. Administer the scheduled dose.
• C. Calculate the safe dose range.
• D. Review the serum digoxin level.

Correct answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario since the heart rate of 128 bpm is within an acceptable range for a 2-year-old child with heart failure. Monitoring for signs of digoxin toxicity is important; however, the immediate action required is to administer the scheduled dose as prescribed based on the heart rate assessment.

2. A child who weighs 25 kg is receiving IV ampicillin 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?

• A. 1875 mg
• B. 625 mg
• C. 2000 mg
• D. 1500 mg

Correct answer: A

Rationale: To calculate the dose for each administration, multiply the child's weight (25 kg) by the dose (300 mg/kg/24 hours) and divide by the number of doses per day (6, as doses are every 4 hours). This gives us (25 kg * 300 mg/kg / 24 hours) / 6 doses = 1875 mg. Therefore, the nurse should administer 1875 mg for each dose. Choice B, 625 mg, is incorrect as it does not consider the correct calculation based on the weight and prescribed dose. Choice C, 2000 mg, is incorrect as it is not derived from the correct dosage calculation. Choice D, 1500 mg, is incorrect as it does not reflect the accurate dosage calculation based on the weight of the child and the prescribed dose.

3. A two-year-old child with heart failure is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?

• A. Determine the pulse deficit.
• B. Administer the scheduled dose.
• C. Calculate the safe dose range.
• D. Review the serum digoxin level.

Correct answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario as the heart rate of 128 bpm falls within the acceptable range for a two-year-old child with heart failure. It indicates that the child may benefit from the therapeutic effects of digoxin. Monitoring the heart rate closely after administration is essential to ensure the medication's effectiveness and safety. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is within the acceptable range. Calculating the safe dose range (Choice C) is not needed since the heart rate is already within the expected parameters. Reviewing the serum digoxin level (Choice D) is not the immediate action required in this case where the heart rate is within the normal range.

4. A 10-year-old child is admitted with diabetic ketoacidosis (DKA). Which laboratory value should the practical nurse (PN) anticipate?

• A. Elevated blood glucose.
• B. Decreased serum ketones.
• C. Low urine glucose.
• D. High bicarbonate levels.

Correct answer: A

Rationale: In a case of diabetic ketoacidosis (DKA), the primary feature is elevated blood glucose levels due to insulin deficiency. Additionally, ketones are increased in the blood and urine. Bicarbonate levels are usually low because of the metabolic acidosis that accompanies DKA. Therefore, the practical nurse should anticipate elevated blood glucose levels as a characteristic laboratory finding in a child admitted with DKA. Choice B is incorrect because serum ketones are increased in DKA. Choice C is incorrect because in DKA, urine glucose is typically high due to spillage of glucose into the urine. Choice D is incorrect because bicarbonate levels are usually low in DKA, not high.

5. A child with Graves' disease who is taking propranolol (Inderal) is seen in the clinic. The nurse should monitor the child for which therapeutic response?

• A. Increased weight gain
• B. Decreased heart rate
• C. Reduced headaches
• D. Diminished fatigue

Correct answer: B

Rationale: When a child with Graves' disease is prescribed propranolol (Inderal), the nurse should monitor for a decreased heart rate as a therapeutic response. Propranolol is a beta-blocker that acts to slow down the heart rate, which is beneficial in managing the symptoms of Graves' disease, such as tachycardia and other cardiovascular manifestations. Choices A, C, and D are incorrect because propranolol is not typically associated with increased weight gain, reduced headaches, or diminished fatigue as its primary therapeutic effect in this context.
