Nursing Elites

1. A 16-year-old female student with a history of asthma controlled with both an oral antihistamine and an albuterol (Proventil) metered-dose inhaler (MDI) comes to the school nurse. The student complains that she cannot sleep at night, feels shaky and her heart feels like it is 'beating a mile a minute.' Which information is most important for the nurse to obtain?

• A. When she last took the antihistamine.
• B. When her last asthma attack occurred.
• C. Duration of most asthma attacks.
• D. How often the MDI is used daily.

Correct answer: D

Rationale: The most important information for the nurse to obtain in this scenario is how often the MDI is used daily. This is crucial to assess if the symptoms the student is experiencing, such as insomnia, shakiness, and tachycardia, could be related to overuse of the inhaler. Overuse of albuterol can lead to side effects like tremors, palpitations, and difficulty sleeping, so understanding the frequency of MDI use is key in determining a potential cause for the student's symptoms. Options A, B, and C are not as pertinent in this situation as they do not directly address the possible link between the student's symptoms and the use of the albuterol MDI.

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 child receives a prescription for amantadine 42 mg PO BID. Amantadine is available as a 50 mg/5 mL syrup. Using a supplied calibrated measuring device, how many mL should be administered per dose? (Round to the nearest tenth.)

• A. 4.2 mL
• B. 5 mL
• C. 3.6 mL
• D. 4 mL

Correct answer: A

Rationale: To calculate the mL per dose, divide the prescribed dose (42 mg) by the concentration of the syrup (50 mg/5 mL) and then convert the result to mL. 42 mg / 50 mg = 0.84. To find the amount in mL, multiply 0.84 by 5 mL, which equals 4.2 mL. Therefore, 4.2 mL should be administered per dose.

4. 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. 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.

5. In a hospitalized child receiving IV fluids for dehydration, what is the best indicator that the child’s dehydration is improving?

• A. The child’s urine output increases
• B. The child’s skin turgor is normal
• C. The child’s weight increases
• D. The child’s vital signs are stable

Correct answer: A

Rationale: An increase in urine output is a reliable indicator of improving dehydration in a child. It signifies that the kidneys are functioning better, helping to restore fluid balance in the body. Monitoring urine output is crucial in assessing hydration status and response to treatment. Choices B, C, and D are not the best indicators of improving dehydration. Normal skin turgor is helpful but may not change immediately with improving hydration. Weight increase may reflect retained fluids rather than improved hydration status. Stable vital signs are important but may not always indicate improving dehydration.
