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. An older adult woman with a long history of COPD is admitted with progressive shortness of breath and a persistent cough, is anxious, and is complaining of dry mouth. Which intervention should the nurse implement?

• A. Administer a prescribed sedative
• B. Encourage client to drink water
• C. Apply a high flow venturi mask
• D. Assist her to an upright position

Correct answer: D

Rationale: Assisting the client to an upright position is the most appropriate intervention in this situation. Placing the client upright helps improve lung expansion by reducing diaphragmatic pressure, facilitating better air exchange, and increasing oxygenation. This position also aids in easing breathing efforts. Administering a sedative (Choice A) may further depress the respiratory system, worsening the breathing problem. Encouraging the client to drink water (Choice B) may not directly address the respiratory distress caused by COPD. Applying a high flow venturi mask (Choice C) may be beneficial in some cases but assisting the client to an upright position should be the priority to optimize respiratory function.

3. What is the main characteristic of cystic fibrosis?

• A. Multiple upper respiratory infections
• B. An underproduction of exocrine glands
• C. Excessive, thick mucus
• D. An overproduction of thin mucus

Correct answer: C

Rationale: The main characteristic of cystic fibrosis is the production of excessive, thick mucus. This thick mucus leads to blockages in the airways, digestive system, and other organs. Choice A is incorrect because while individuals with cystic fibrosis are more prone to respiratory infections, the main characteristic is the mucus production. Choice B is incorrect as cystic fibrosis is characterized by the overproduction, not underproduction, of exocrine glands. Choice D is also incorrect as the mucus produced in cystic fibrosis is thick, not thin.

4. 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.

5. The nurse is assessing a client who has herpes zoster. Which question will allow the nurse to gather further information about this condition?

• A. Has everyone at home already had varicella?
• B. Have the antifungal creams been effective?
• C. Do your family members share combs and brushes?
• D. Do you have any dry patches on your feet and hands?

Correct answer: A

Rationale: The correct answer is A: 'Has everyone at home already had varicella?' Herpes zoster (shingles) is caused by the reactivation of the varicella-zoster virus, the same virus that causes chickenpox. By knowing if others at home had varicella (chickenpox), the nurse can assess the risk of transmission and provide appropriate guidance. Choice B is incorrect because antifungal creams are not effective for herpes zoster, which is a viral infection. Choice C is irrelevant to herpes zoster as it pertains to sharing personal items that may transmit head lice or certain skin infections. Choice D is also unrelated as it focuses on dry patches, not typical manifestations of herpes zoster which presents as a painful rash.
