Nursing Elites

1. A child admitted with diabetic ketoacidosis is demonstrating Kussmaul respirations. The nurse determines that the increased respiratory rate is a compensatory mechanism for which acid-base alteration?

• A. Metabolic alkalosis.
• B. Respiratory acidosis.
• C. Respiratory alkalosis.
• D. Metabolic acidosis.

Correct answer: D

Rationale: Kussmaul respirations are deep, rapid breathing patterns observed in metabolic acidosis, such as diabetic ketoacidosis. In this condition, the body tries to compensate for the acidic environment by increasing the respiratory rate to eliminate excess carbon dioxide (CO2) and decrease the acid levels, thereby helping to correct the acid-base imbalance. Therefore, the correct answer is metabolic acidosis.

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. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarctation of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left to right shunt

Correct answer: B

Rationale: The findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

4. When caring for a child with Kawasaki disease, which symptom is the most significant for making this diagnosis?

• A. Desquamation of the palms and soles.
• B. Cervical lymphadenopathy.
• C. Erythema of the hands and feet.
• D. Strawberry tongue.

Correct answer: C

Rationale: Erythema of the hands and feet is a key diagnostic criterion for Kawasaki disease. This, along with other symptoms like fever and strawberry tongue, helps in making the diagnosis. While desquamation of the palms and soles, cervical lymphadenopathy, and strawberry tongue are associated with Kawasaki disease, the presence of erythema of the hands and feet is particularly significant in diagnosing this condition.

5. An adolescent’s mother calls the primary HCP’s office to inquire about the results of her daughter’s serum test that was drawn last week. Since it is the teenager’s 18th birthday, how should the nurse respond to this mother’s inquiry?

• A. Ask when the adolescent was last seen in the clinic
• B. Tell the mother to have the teenager call the clinic
• C. Since the serum sample was drawn last week, provide the mother with the findings
• D. Explain that the information cannot be released without the 18-year-old's permission

Correct answer: D

Rationale: When an individual turns 18, they are considered a legal adult and have the right to privacy regarding their medical information. Therefore, the nurse should explain to the mother that without the 18-year-old's permission, the results cannot be disclosed.
