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. 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.

3. A healthcare provider assesses a client with pneumonia. Which clinical manifestation should the provider expect to find?

• A. Fremitus
• B. Hyperresonance
• C. Dullness on percussion
• D. Decreased tactile fremitus

Correct answer: C

Rationale: Pneumonia often leads to the consolidation of lung tissue, resulting in dullness on percussion. This occurs due to the presence of fluid or inflammatory material in the alveoli. Fremitus and decreased tactile fremitus are more indicative of conditions like pleural effusion or pneumothorax, where there is an increase in the density of the pleural space or air in the pleural cavity. Hyperresonance, on the other hand, is typically associated with conditions causing air trapping, such as emphysema, where there is increased air in the alveoli.

4. A client who experienced a femur fracture 8 hr ago now reports sudden onset dyspnea and severe chest pain. Which of the following actions should the nurse take first?

• A. Provide high-flow oxygen.
• B. Check the client for a positive Chvostek's sign.
• C. Administer an IV vasopressor medication.
• D. Monitor the client for headache.

Correct answer: A

Rationale: In this situation, the priority action is to provide high-flow oxygen to the client. Sudden onset dyspnea and severe chest pain can be indicative of a pulmonary embolism, which is a life-threatening emergency. Oxygen therapy helps improve oxygenation and stabilizes the client's condition. Checking for Chvostek's sign, administering IV vasopressors, or monitoring for a headache are not the immediate priorities in this critical situation.

5. While caring for a client using O2 in the hospital, what assessment finding indicates that goals for a priority diagnosis are being met?

• A. 100% of meals being eaten by the client
• B. Intact skin behind the ears
• C. The client understanding the need for oxygen
• D. Unchanged weight for the past 3 days

Correct answer: B

Rationale: When a client is using oxygen, there is a risk for impaired skin integrity due to pressure from tubing. Intact skin behind the ears suggests that the client is not experiencing skin breakdown, meeting the goals for this diagnosis. The client's nutrition, understanding of oxygen therapy, and weight stability are important but do not directly relate to the priority diagnosis of skin integrity in this context.
