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 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.

3. A home health nurse visits a client who has COPD and receives oxygen at 2 L/min via nasal cannula. The client reports difficulty breathing. Which of the following actions is the nurse's priority?

• A. Increase the oxygen flow to 3 L/min.
• B. Assess the client's respiratory status.
• C. Call emergency services for the client.
• D. Have the client cough and expectorate secretions.

Correct answer: B

Rationale: When a client with COPD on oxygen therapy reports difficulty breathing, the priority action for the nurse is to assess the client's respiratory status. This involves evaluating the client's oxygen saturation levels, respiratory rate, effort of breathing, lung sounds, and overall respiratory distress. By assessing the client's respiratory status, the nurse can determine the severity of the situation and make appropriate decisions regarding further interventions, such as adjusting oxygen flow rate, providing respiratory treatments, or seeking emergency assistance if necessary.

4. A client has developed atelectasis postoperatively. Which of the following findings should the nurse expect?

• A. Facial flushing
• B. Increasing dyspnea
• C. Decreasing respiratory rate
• D. Friction rub

Correct answer: B

Rationale: Atelectasis is a condition where the alveoli in the lungs collapse, leading to impaired gas exchange. As a result, the client may experience increasing dyspnea (difficulty breathing) due to the decreased lung capacity for oxygen exchange. Facial flushing, decreasing respiratory rate, and friction rub are not typically associated with atelectasis.

5. A client with chronic obstructive pulmonary disease (COPD) is being assessed by a nurse. Which finding should the nurse expect?

• A. Increased anterior-posterior (AP) chest diameter
• B. Decreased respiratory rate
• C. Weight gain
• D. Productive cough with yellow sputum

Correct answer: A

Rationale: In chronic obstructive pulmonary disease (COPD), clients often develop a barrel chest, characterized by an increased anterior-posterior diameter of the chest due to hyperinflation of the lungs. This change in chest shape is a common finding in COPD. Decreased respiratory rate, weight gain, and productive cough with yellow sputum are not typical findings associated with COPD.
