Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) presented with shortness of breath. Oxygen therapy was started at 2 liters/minute via nasal cannula. The arterial blood gases (ABGs) after treatment were pH 7.36, PaO2 52, PaCO2 59, HCO3 33. Which statement describes the most likely cause of the simultaneous increase in both PaO2 and PaCO2?

• A. The client is hyperventilating due to anxiety.
• B. The hypoxic drive was reduced by the oxygen therapy.
• C. The client is experiencing respiratory alkalosis.
• D. The client is experiencing metabolic acidosis.

Correct answer: B

Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.

2. A client with cirrhosis is receiving lactulose. What is the desired effect of this medication?

• A. Decrease blood glucose levels
• B. Reduce serum ammonia levels
• C. Increase platelet count
• D. Lower serum bilirubin levels

Correct answer: B

Rationale: The correct answer is B: Reduce serum ammonia levels. Lactulose is used to reduce serum ammonia levels in clients with cirrhosis, helping to prevent hepatic encephalopathy. Lactulose works by acidifying the colon, trapping ammonia for excretion. Decreasing blood glucose levels (choice A) is not the primary effect of lactulose. Increasing platelet count (choice C) and lowering serum bilirubin levels (choice D) are not direct effects of lactulose in the management of cirrhosis.

3. Which intervention should the nurse include in the plan of care for a client who has a chest tube due to hemothorax?

• A. Keep the arm and shoulder of the affected side immobile at all times.
• B. Encourage the client to breathe deeply and cough at frequent intervals.
• C. Maintain the pleura vac slightly above the chest level.
• D. Ensure there is no fluctuation in the water seal.

Correct answer: B

Rationale: Encouraging deep breathing and coughing is vital for a client with a chest tube due to hemothorax as it helps prevent atelectasis and promotes lung expansion. Keeping the arm and shoulder immobile (Choice A) is not necessary for chest tube management. Maintaining the pleura vac slightly above the chest level (Choice C) is incorrect as the pleura vac should be kept below the chest level to facilitate drainage. Ensuring no fluctuation in the water seal (Choice D) is important, but it is not the priority intervention when compared to promoting lung expansion through deep breathing and coughing.

4. A client who has a history of unstable angina is admitted to the emergency department with chest pain.

• A. Chest pain relieved by rest.
• B. Chest pain unrelieved after taking 3 sequential nitroglycerin tablets.
• C. Chest pain occurring only with exertion.
• D. Chest pain lasting less than 5 minutes.

Correct answer: B

Rationale: Chest pain unrelieved after taking 3 sequential nitroglycerin tablets indicates a possible myocardial infarction and requires immediate medical attention.

5. A client with partial-thickness burns to the lower extremities is scheduled for whirlpool therapy to debride the burned area. Which intervention should the nurse implement before transporting the client to the physical therapy department?

• A. Apply a sterile dressing to the wound.
• B. Administer an analgesic.
• C. Encourage the client to drink fluids.
• D. Ensure the client's nutritional needs are met.

Correct answer: B

Rationale: Administering an analgesic before whirlpool therapy is the priority intervention in this scenario. Whirlpool therapy for debridement can be painful for the client with partial-thickness burns. Administering an analgesic before the procedure helps manage pain during the debridement process, ensuring the client's comfort. Applying a sterile dressing (Choice A) may be necessary after the whirlpool therapy but is not the immediate pre-transport intervention. Encouraging the client to drink fluids (Choice C) and ensuring nutritional needs are met (Choice D) are important aspects of care but are not specifically related to preparing the client for whirlpool therapy.
