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 chronic obstructive pulmonary disease (COPD) who has been receiving oxygen therapy at 2 L/min now has a respiratory rate of 10 breaths/min. What action should the nurse take first?

• A. Increase the oxygen flow rate to 4 L/min.
• B. Administer a bronchodilator via nebulizer.
• C. Encourage the client to take deep breaths.
• D. Assess the client's mental status and level of consciousness.

Correct answer: D

Rationale: The priority action for the nurse is to assess the client's mental status and level of consciousness. This assessment helps determine if the decreased respiratory rate is affecting the client's oxygenation. By evaluating the client's mental status and level of consciousness, the nurse can promptly identify any signs of respiratory distress or hypoxia, allowing for timely intervention and appropriate adjustments to the oxygen therapy or other treatments.

3. Which action best demonstrates respect for autonomy when working with a client?

• A. Asks if the client has questions before signing a consent form
• B. Provides the client with accurate information when questioned
• C. Honors the promises made to the client and family
• D. Ensures fair treatment of the client compared to others

Correct answer: A

Rationale: Respect for autonomy involves allowing individuals to make decisions about their care. By asking if the client has questions before signing a consent form, the nurse is respecting the client's right to make informed choices and decisions regarding their healthcare. This action supports the principle of self-determination and autonomy in healthcare decision-making.

4. A client with asthma is assessed by a nurse and presents with bilateral wheezing, decreased pulse oxygen saturation, and suprasternal retraction on inhalation. Which actions should the nurse take? (Select all that apply)

• A. Administer prescribed albuterol (Ventolin) inhaler.
• B. Assess the client for tracheal deviation.
• C. Administer oxygen to maintain saturations greater than 94%.
• D. Perform peak expiratory flow measurements.

Correct answer: C

Rationale: Suprasternal retraction during inhalation indicates the use of accessory muscles and difficulty in moving air due to airway narrowing, supported by bilateral wheezing and decreased pulse oxygen saturation. This client needs immediate intervention as their asthma is not responding to the medication. Administering oxygen to maintain saturations above 94% is crucial to ensure adequate oxygenation. While administering a rescue inhaler could also be necessary, oxygen therapy takes priority in this situation.

5. While dining at a restaurant, a person begins to choke. Which of the following actions should the nurse take?

• A. Instruct the person to call 911.
• B. Ask the person if he/she can speak.
• C. Use the jaw-thrust maneuver.
• D. Perform abdominal thrusts.

Correct answer: B

Rationale: When encountering a choking individual, the nurse should first assess the person's ability to speak. If the person can speak, it indicates that their airway is partially obstructed, allowing some air to pass. In this case, encouraging the person to continue coughing and monitoring them closely may be appropriate. If the person cannot speak, it may suggest a complete airway obstruction and immediate intervention is required. Instructing the person to call 911 (Choice A) may be necessary if the situation worsens. Using the jaw-thrust maneuver (Choice C) is not appropriate for a choking victim. Performing abdominal thrusts (Choice D) is typically recommended for conscious choking victims, not chest compressions.
