Correct Answer: A

Rationale: Encouraging the client to increase fluid intake is essential to promote airway clearance in pneumonia. Adequate hydration helps to thin respiratory secretions, making them easier to expectorate. Suctioning every 2 hours may be too frequent and can lead to airway trauma and irritation. Chest physiotherapy is not typically indicated for pneumonia unless there are specific complications. Administering oxygen via nasal cannula may be necessary to maintain oxygen saturation but does not directly promote airway clearance.

Correct Answer: B

Rationale: An oxygen saturation of 88% indicates hypoxemia, which is a serious condition post-gastrectomy. Hypoxemia can lead to inadequate oxygen delivery to tissues, potentially causing complications like organ dysfunction or failure. This finding requires immediate attention to prevent further deterioration. The heart rate, respiratory rate, and temperature are within normal ranges for a client post-gastrectomy, so they do not require immediate reporting to the provider.

Correct Answer: A

Rationale: Administering oxygen is the most appropriate initial response to a patient experiencing confusion after surgery. Confusion can be a sign of hypoxia, which is inadequate oxygen supply to the brain. Administering oxygen helps ensure that the patient is getting enough oxygen, addressing a potential cause of the confusion. Repositioning the patient, encouraging deep breathing exercises, or performing a neurological exam may be necessary depending on the situation, but addressing potential hypoxia should be the priority in a confused post-operative patient.

Correct Answer: A

Rationale: Administering oxygen is the most critical intervention for a patient in respiratory distress as it helps improve oxygenation levels. Oxygen therapy aims to increase oxygen saturation in the blood, providing relief and support during episodes of respiratory distress. Administering bronchodilators may be beneficial in some cases, but oxygen therapy takes precedence in addressing the underlying issue of inadequate oxygenation. Repositioning the patient may help optimize ventilation but does not directly address the primary need for increased oxygen. Providing humidified air can offer comfort but does not address the urgent need for improved oxygen levels in a patient experiencing respiratory distress.

Correct Answer: C

Rationale: A weight gain of 2 kg (4.4 lb) in 2 days can indicate fluid retention, which is a sign of worsening heart failure and should be reported. This rapid weight gain suggests a fluid overload, putting the client at risk for complications. A heart rate of 90/min is slightly elevated but not as concerning as a sudden significant weight gain. The serum potassium level of 4.0 mEq/L is within the normal range and does not directly indicate worsening heart failure. A heart rate of 76/min is within the normal range and does not raise immediate concerns related to heart failure.
