Nursing Elites

1. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?

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

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.

2. A client with severe dehydration is admitted to the hospital. Which assessment finding indicates that the client's condition is improving?

• A. The client reports feeling less thirsty
• B. Urine output increases to 40 mL/hour
• C. Heart rate decreases from 120 to 110 beats per minute
• D. Skin turgor returns to normal

Correct answer: B

Rationale: An increase in urine output is a reliable indicator that the client's hydration status is improving. This reflects adequate fluid replacement and improved kidney function. Choice A is subjective and may not always indicate improved hydration. Choice C, while a positive sign, may be influenced by other factors such as medications or pain. Choice D, skin turgor returning to normal, is a delayed indicator of hydration status and may take time to improve even after hydration is initiated.

3. A preschool-aged boy is admitted to the pediatric unit following successful resuscitation from a near-drowning incident. While providing care to the child, the nurse begins talking with his preadolescent brother who rescued the child from the swimming pool and initiated resuscitation. The nurse notices the older boy becomes withdrawn when asked about what happened. Which action should the nurse take?

• A. Involve the older brother in supporting the child
• B. Ask the older brother how he felt during the incident
• C. Ask the parents for more information about the brother's behavior
• D. Reassure the brother that everything is fine now

Correct answer: B

Rationale: The older brother's withdrawal likely indicates emotional trauma or stress from the near-drowning event. Asking how he felt provides an opportunity for emotional support and allows the child to express feelings that may need addressing. Involving him in supporting the child may be overwhelming and not address his emotional needs directly. Asking the parents for more information may not allow the older brother to express his own feelings. Simply reassuring him that everything is fine now may dismiss his emotional experience without providing a chance for him to process his feelings.

4. The nurse is caring for a preterm newborn with nasal flaring, grunting, and sternal retractions. After administering surfactant, which assessment is most important for the nurse to monitor?

• A. Bowel sounds
• B. Heart rate
• C. Arterial blood gases
• D. Apnea episodes

Correct answer: C

Rationale: Corrected Rationale: Surfactant therapy is used to improve lung function and gas exchange in premature infants with respiratory distress. Monitoring arterial blood gases is essential to assess the effectiveness of the treatment and ensure adequate oxygenation. While monitoring heart rate is important in neonatal care, assessing arterial blood gases will provide direct information regarding the infant's oxygenation status post-surfactant administration. Bowel sounds are not directly related to the respiratory distress symptoms described, and monitoring apnea episodes, although important in preterm infants, is not the most crucial assessment immediately following surfactant administration.

5. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote oxygenation by improving lung expansion
• C. To encourage use of accessory muscles for breathing
• D. To drain secretions and prevent aspiration

Correct answer: D

Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.
