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 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.

3. A client who had coronary artery bypass grafting yesterday needs care. What actions can the nurse delegate to the unlicensed assistive personnel (UAP)? (SATA)

• A. administer antibiotics every 4 hrs
• B. Encourage the client to use the spirometer every 4 hours.
• C. Ensure the client wears TED hose or sequential compression devices.
• D. Have the client rate pain on a 0-to-10 scale and report to the nurse.

Correct answer: C

Rationale: The nurse can delegate tasks such as assisting the client to get up in the chair or ambulate to the bathroom, applying TED hose or sequential compression devices, and taking/recording vital signs to the unlicensed assistive personnel (UAP). Using the spirometer should be encouraged every hour the day after surgery by the nurse. Assessing pain using a 0-to-10 scale is a nursing assessment. However, if the client reports pain, the UAP should inform the nurse for a more detailed assessment.

4. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which assessment finding requires the nurse to take immediate action?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 22 breaths per minute
• C. Client reports shortness of breath
• D. Client's respiratory rate decreases to 10 breaths per minute

Correct answer: D

Rationale: A decrease in the client's respiratory rate to 10 breaths per minute, while receiving oxygen therapy for COPD, is a concerning finding that may indicate carbon dioxide retention and respiratory depression. This situation requires immediate action to prevent further complications. An oxygen saturation of 90% is within an acceptable range for COPD patients on oxygen therapy. A respiratory rate of 22 breaths per minute and reports of shortness of breath are common in clients with COPD and may not necessitate immediate action unless accompanied by other concerning symptoms.

5. A client learns about pursed-lip breathing. Which statement by the client indicates teaching has been effective?

• A. I will breathe in quickly through my mouth and out through my nose.
• B. I will breathe in slowly through my nose and out through pursed lips.
• C. I will hold my breath for 10 seconds before exhaling.
• D. I will breathe in and out through pursed lips.

Correct answer: B

Rationale: The correct technique for pursed-lip breathing involves inhaling slowly through the nose and exhaling slowly through pursed lips. This technique helps improve expiration and reduce air trapping. Breathing in quickly, holding the breath, or breathing in and out through pursed lips does not align with the correct method of pursed-lip breathing.
