Correct Answer: A

Rationale: The most important assessment for a patient with suspected pneumonia is to monitor lung sounds. Lung sounds provide crucial information about the severity of pneumonia, such as crackles or decreased air entry. This assessment helps in evaluating the effectiveness of ventilation and oxygenation. While checking oxygen saturation is important, monitoring lung sounds gives more direct information about the lung involvement in pneumonia. Assessing for cough and fever are also relevant but do not provide as direct and critical information as monitoring lung sounds in the context of suspected pneumonia.

Correct Answer: B

Rationale: The correct answer is B: 'Heart rate of 88/min.' A heart rate of 88/min in a postoperative client can be an early sign of bleeding or other complications. It is essential to report this finding promptly to the healthcare provider for further evaluation and intervention. Choices A, C, and D are within normal ranges for a postoperative client and do not indicate immediate concern. A blood pressure of 118/76 mm Hg is normal, urinary output of 30 mL/hr may be adequate depending on the client's fluid status, and a hematocrit of 42% is within the acceptable range for a postoperative client. Therefore, they do not require immediate reporting.

Correct Answer: C

Rationale: Albuterol is a short-acting beta-agonist bronchodilator used to quickly relieve bronchospasm in clients with asthma who are experiencing wheezing. Fluticasone is an inhaled corticosteroid used for long-term control of asthma symptoms and not for acute wheezing. Montelukast is a leukotriene receptor antagonist used for long-term asthma management, not for immediate relief of wheezing. Ipratropium is an anticholinergic bronchodilator used for chronic obstructive pulmonary disease (COPD) and not typically used as the first-line treatment for asthma exacerbation.

Correct Answer: C

Rationale: Elevating the head of the bed to 45 degrees during feedings is the correct intervention to prevent aspiration in clients with a nasogastric tube. This position helps reduce the risk of regurgitation and subsequent aspiration of stomach contents into the lungs. Flushing the tube with water before feedings (Choice A) is not necessary for preventing aspiration. Checking for gastric residuals (Choice B) helps monitor feeding tolerance but does not directly prevent aspiration. Placing the client in the left lateral position (Choice D) is not specifically indicated for preventing aspiration in a client with a nasogastric tube.
