Nursing Elites

1. A 4-month-old girl is brought to the clinic by her mother because she has had a cold for 2 to 3 days and woke up this morning with a hacking cough and difficulty breathing. Which additional assessment finding should alert the nurse that the child is in acute respiratory distress?

• A. Bilateral bronchial breath sounds.
• B. Diaphragmatic respiration.
• C. A resting respiratory rate of 35 breaths per minute.
• D. Flaring of the nares.

Correct answer: D

Rationale: Flaring of the nares is a clinical sign of acute respiratory distress in infants. It indicates an increased effort to breathe and is a crucial finding that requires immediate attention, as it signifies the child is having difficulty breathing and may be in respiratory distress. Choices A, B, and C are incorrect. Bilateral bronchial breath sounds may be present in conditions like pneumonia but do not specifically indicate acute respiratory distress. Diaphragmatic respiration is a normal breathing pattern and not a sign of distress. A resting respiratory rate of 35 breaths per minute in a 4-month-old infant is within the expected range, so it does not necessarily indicate acute respiratory distress.

2. The nurse is caring for a 3-year-old child who has been recently diagnosed with cystic fibrosis. Which discharge instruction by the nurse is most important to promote pulmonary function?

• A. Chest physiotherapy should be performed before meals and at bedtime
• B. Cough suppressants can be used up to four times a day for relief
• C. Oxygen should be given through a nasal cannula between 4-6 L/min
• D. Exercise is discouraged in order to preserve pulmonary vital capacity

Correct answer: B

Rationale: In cystic fibrosis, thick mucus obstructs the airways, making it difficult to clear from the lungs. Cough suppressants can help reduce the discomfort associated with persistent coughing, allowing the child to cough more effectively to clear the mucus, thus promoting pulmonary function. Chest physiotherapy, not exercise, helps mobilize the mucus. Oxygen therapy may be needed but is not the most important for promoting pulmonary function in this case.

3. The healthcare provider is evaluating the effects of thyroid therapy used to treat a 5-month-old with hypothyroidism. Which behavior indicates that the treatment has been effective?

• A. Laughs readily, turns from back to side.
• B. Has strong Moro and tonic neck reflexes.
• C. Keeps fists clenched, opens hands when grasping an object.
• D. Can lift head, but not chest when lying on abdomen.

Correct answer: A

Rationale: The ability to laugh readily and turn from back to side indicates the effectiveness of thyroid therapy and normal development in a 5-month-old. These behaviors suggest improved muscle tone and motor skills, which are positive outcomes of thyroid hormone replacement therapy for hypothyroidism. Choices B, C, and D describe developmental milestones that are not specific indicators of the effectiveness of thyroid therapy in treating hypothyroidism in a 5-month-old.

4. A child who is admitted to the hospital with anemia is anxious, fearful, and hyperventilating. The nurse anticipates the child developing which acid-base imbalance?

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

Correct answer: C

Rationale: In this scenario, the child is hyperventilating, which leads to excessive loss of carbon dioxide. This loss of carbon dioxide causes respiratory alkalosis due to a decrease in the partial pressure of carbon dioxide in the blood. Therefore, the correct answer is respiratory alkalosis. Choices A, B, and D are incorrect. Metabolic acidosis is characterized by a decrease in pH and bicarbonate levels due to conditions like kidney disease. Respiratory acidosis is caused by retention of carbon dioxide, leading to an increase in the partial pressure of carbon dioxide. Metabolic alkalosis results from a loss of acid or an increase in bicarbonate levels.

5. 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.
