1. A 5-week-old infant with hypertrophic pyloric stenosis has developed projectile vomiting over the last two weeks. Which intervention should the nurse plan to implement?

Correct answer: D

Rationale: The correct intervention for a 5-week-old infant with hypertrophic pyloric stenosis presenting with projectile vomiting is to maintain intravenous fluid therapy. This is essential to maintain hydration before surgery. Instructing the mother to give sugar water only (Choice A) is inadequate and does not address the need for proper hydration. Offering oral rehydration every 2 hours (Choice B) may not be effective in cases of severe vomiting and could lead to further fluid loss. Providing Pedialyte feedings via nasogastric tube (Choice C) is an option, but in severe cases, intravenous fluid therapy is more effective in ensuring hydration and electrolyte balance.

2. A client is admitted with a large pleural effusion. Which procedure should the nurse prepare the client for?

Correct answer: A

Rationale: Corrected Rationale: The correct procedure for a client with a large pleural effusion is thoracentesis. Thoracentesis is a diagnostic and therapeutic procedure used to remove fluid from the pleural space, which can help relieve symptoms associated with pleural effusion. Choice B (Endotracheal intubation) is incorrect as it is a procedure to secure the airway by placing a tube into the trachea. Choice C (Chest tube insertion) is incorrect as it is typically done to drain air or fluid from the pleural space over a longer period. Choice D (Bronchoscopy) is incorrect as it is a procedure used to visualize the airways and diagnose lung conditions, not specifically for pleural effusion removal.

3. A client with heart failure reports nausea, vomiting, yellow vision, and palpitations. What should the nurse assess first?

Correct answer: B

Rationale: The combination of nausea, vomiting, yellow vision, and palpitations in a heart failure patient is indicative of digoxin toxicity. The nurse should first obtain a list of the client's medications to verify if they are taking digoxin.

4. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving oxygen therapy. Which assessment finding indicates that the client's oxygenation is improving?

Correct answer: A

Rationale: A pulse oximetry reading of 94% indicates adequate oxygenation. Monitoring oxygen saturation is the most objective way to assess the effectiveness of oxygen therapy. Choices B, C, and D do not directly reflect the client's oxygenation status. An increase in heart rate or respiratory rate may indicate increased work of breathing or stress on the body. The client reporting increased energy levels is subjective and may not directly correlate with improved oxygenation.

5. A client with pneumonia is receiving intravenous (IV) antibiotics. Which assessment finding indicates that the client's condition is improving?

Correct answer: B

Rationale: A decrease in white blood cell count indicates that the infection is responding to treatment and the client's condition is improving. Monitoring the white blood cell count is a more objective indicator of the body's response to the antibiotics. Choices A, C, and D may also be positive signs, but they are less specific and may vary among individuals. Respiratory rate alone may not be sufficient to indicate improvement, as other factors can influence it. Energy levels and cough characteristics are subjective and may not always correlate with the effectiveness of antibiotic treatment.
