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 is receiving oxygen therapy via nasal cannula. Which finding indicates that the therapy is effective?

• A. The client is able to ambulate in the hall without dyspnea.
• B. The client has a respiratory rate of 24 breaths per minute.
• C. The client's oxygen saturation is 92%.
• D. The client has a productive cough.

Correct answer: A

Rationale: The correct answer is A. Effective oxygen therapy should improve the client's ability to perform activities without dyspnea. This indicates that the oxygen therapy is adequately supporting the client's respiratory needs. An oxygen saturation of 92% may suggest the need for a higher flow rate to improve oxygenation. A respiratory rate of 24 breaths per minute is elevated, indicating potential respiratory distress. A productive cough does not necessarily indicate effective oxygen therapy, as it is a symptom of respiratory irritation or infection, not oxygenation status.

3. A healthcare professional auscultates a harsh hollow sound over a client's trachea & larynx. Which action should the healthcare professional take first?

• A. Document findings.
• B. Administer O2 therapy.
• C. Position client in high-Fowler's position.
• D. Administer prescribed albuterol.

Correct answer: A

Rationale: The healthcare professional has identified bronchial breath sounds, which are normal findings over the trachea & larynx, characterized by harsh, hollow, tubular, and blowing sounds. The appropriate initial action for the healthcare professional is to document these normal findings. Oxygen therapy, administering albuterol, or repositioning the client is unnecessary as this finding does not indicate a need for intervention.

4. A client in an emergency department has a sucking chest wound resulting from a gunshot. The client has a blood pressure of 100/60 mm Hg, a weak pulse rate of 118/min, and a respiratory rate of 40/min. Which of the following actions should the nurse take?

• A. Raise the foot of the bed to a 90� angle
• B. Remove the dressing to inspect the wound
• C. Prepare to insert a central line
• D. Administer oxygen via nasal cannula

Correct answer: D

Rationale: In a client with a sucking chest wound, the priority is to administer oxygen via nasal cannula to improve oxygenation. The client's blood pressure, weak pulse rate, and elevated respiratory rate indicate hypovolemic shock, so increasing oxygen supply is crucial. Raising the foot of the bed, removing the dressing, or preparing to insert a central line are not immediate actions needed for a client with a sucking chest wound and signs of shock.

5. A client has a tracheostomy that is 3 days old. Upon assessment, the nurse notes the client's face is puffy, and the eyelids are swollen. What action by the nurse takes priority?

• A. Assess the client's oxygen saturation.
• B. Notify the Rapid Response Team.
• C. Oxygenate the client with a bag-valve-mask.
• D. Palpate the skin of the upper chest.

Correct answer: A

Rationale: In this scenario, the client may have subcutaneous emphysema, where air leaks into the tissues surrounding the tracheostomy. The priority action for the nurse is to assess the client's oxygen saturation and other indicators of oxygenation to ensure adequate oxygen supply. If the client is stable, the nurse can then proceed to palpate the skin of the upper chest to check for subcutaneous emphysema. If the client is unstable, the nurse should promptly notify the Rapid Response Team. Using a bag-valve-mask device may be necessary for oxygenating the client, but assessing oxygen saturation comes first to guide further interventions.
