Nursing Elites

1. A child is hospitalized because of persistent vomiting. The nurse should monitor the child closely for which problem?

• A. Diarrhea
• B. Metabolic acidosis
• C. Metabolic alkalosis
• D. Hyperactive bowel sounds

Correct answer: C

Rationale: In the scenario of persistent vomiting, the child is at risk of developing metabolic alkalosis due to the loss of hydrochloric acid. Vomiting leads to the loss of gastric acid, resulting in an imbalance that causes metabolic alkalosis. Metabolic acidosis is incorrect as it would occur in a child with diarrhea due to the loss of bicarbonate. While diarrhea can sometimes be associated with vomiting, in this case, the primary focus is on the effects of vomiting. Hyperactive bowel sounds are not typically associated with vomiting, making this choice less relevant to the situation described.

2. The nurse is caring for a 13-year-old following spinal fusion for scoliosis. Which of the following interventions is appropriate in the immediate post-operative period?

• A. Raise the head of the bed at least 30 degrees
• B. Encourage ambulation within 24 hours
• C. Maintain in a flat position, logrolling as needed
• D. Encourage leg contraction and relaxation after 48 hours

Correct answer: C

Rationale: In the immediate post-operative period following spinal fusion for scoliosis in a 13-year-old, it is important to maintain the patient in a flat position and perform logrolling as needed. This helps prevent injury to the surgical site and ensures proper spinal alignment. Raising the head of the bed at least 30 degrees is contraindicated as it can put strain on the surgical site. Encouraging ambulation within 24 hours may be appropriate in the recovery process but not in the immediate post-operative period. Encouraging leg contraction and relaxation after 48 hours may also be part of the rehabilitation process but is not a priority in the immediate post-operative period.

3. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.

4. A newborn has been diagnosed with hypothyroidism. In discussing the condition and treatment with the family, the nurse should emphasize:

• A. They can expect the child will be mentally retarded.
• B. Administration of thyroid hormone will prevent problems.
• C. This rare problem is always hereditary.
• D. Physical growth/development will be delayed.

Correct answer: B

Rationale: The correct answer is administration of thyroid hormone will prevent problems. In newborns diagnosed with hypothyroidism, early identification and continuous treatment with hormone replacement can correct this condition effectively. Choice A is incorrect as it uses outdated and inappropriate language (mentally retarded) and does not reflect modern understanding of conditions. Choice C is incorrect because while some cases of hypothyroidism can be hereditary, it is not always the case. Choice D is incorrect as physical growth and development can be affected by hypothyroidism, but the critical emphasis should be on the importance of administering thyroid hormone to prevent complications and support normal growth and development.

5. A patient's chart indicates a history of hyperkalemia. Which of the following would you not expect to see with this patient if this condition were acute?

• A. Decreased HR
• B. Paresthesias
• C. Muscle weakness of the extremities
• D. Migraines

Correct answer: D

Rationale: The correct answer is 'Migraines.' Migraines are not a symptom typically associated with hyperkalemia. In acute hyperkalemia, one would not expect to see migraines. Symptoms of hyperkalemia often include muscle weakness, paresthesias, and cardiac manifestations such as bradycardia or even cardiac arrest. Therefore, choices A, B, and C are more commonly associated with acute hyperkalemia compared to migraines, making it the correct choice.
