Nursing Elites

1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

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

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. A client with a mediastinal chest tube is being assessed by a nurse. Which symptoms require the nurse's immediate intervention? (SATA)

• A. Production of pink sputum
• B. Tracheal deviation
• C. Pain at insertion site
• D. Sudden onset of shortness of breath

Correct answer: B

Rationale: Immediate intervention is necessary when a client with a mediastinal chest tube exhibits tracheal deviation since it may indicate a tension pneumothorax. This condition requires prompt attention to prevent serious complications. While the production of pink sputum and pain at the insertion site should be monitored and reported, they do not typically require immediate intervention. Sudden onset of shortness of breath could indicate various issues related to the chest tube but is not as critical as tracheal deviation in this context.

3. A healthcare professional assesses a client's respiratory status. Which information is of highest priority for the healthcare professional to obtain?

• A. Average daily fluid intake
• B. Neck circumference
• C. Height & weight
• D. Occupation & hobbies

Correct answer: D

Rationale: Obtaining information about a client's occupation and hobbies is crucial when assessing respiratory status as many respiratory problems can result from chronic exposure to inhalation irritants related to these activities. Understanding the client's potential exposure can help the healthcare professional identify risk factors and provide appropriate interventions to promote respiratory health.

4. A healthcare provider is assessing a client immediately after the removal of the endotracheal tube. Which of the following findings should the provider report to the healthcare provider?

• A. Stridor
• B. Copious oral secretions
• C. Hoarseness
• D. Sore throat

Correct answer: A

Rationale: Stridor is a high-pitched, harsh respiratory sound that can indicate airway obstruction. It is a serious finding that requires immediate attention as it may lead to respiratory compromise. Copious oral secretions, hoarseness, and sore throat are common but expected findings after endotracheal tube removal and do not typically require urgent intervention.

5. When preparing a client for transfer to the ICU for placement of a pulmonary artery catheter, the nurse should explain that this catheter is used to monitor which of the following conditions?

• A. Intracranial pressure
• B. Spinal cord perfusion
• C. Renal function
• D. Hemodynamic status

Correct answer: D

Rationale: A pulmonary artery catheter is primarily used to monitor hemodynamic status. It provides essential information on cardiac output, preload, afterload, and overall cardiovascular function. This data helps healthcare providers manage the client's fluid status, cardiac function, and guide treatment interventions in critically ill patients. Monitoring intracranial pressure, spinal cord perfusion, or renal function would require different monitoring devices and techniques, not a pulmonary artery catheter.
