A client with chronic obstructive pulmonary disease (COPD tells the nurse, 'I can feel the congestion in my lungs, and I certainly cough a lot, but I can't seem to bring anything up.' Which of the following actions should the nurse take to help this client with tenacious bronchial secretions?
- A. Maintaining a semi-Fowler's position as often as possible
- B. Administering oxygen via nasal cannula at 2 L/min
- C. Helping the client select a low-salt diet
- D. Encouraging the client to drink 2 to 3 L of water daily
Correct Answer: D
Rationale: The correct answer is D: Encouraging the client to drink 2 to 3 L of water daily. Increased fluid intake helps to thin out bronchial secretions, making them easier to cough up. Step-by-step rationale:
1. Increased water intake promotes hydration, which thins mucus in the airways.
2. Thinner mucus is easier to expectorate, aiding in clearing airway congestion.
3. Adequate hydration also helps to prevent dehydration, which can further thicken secretions.
Summary:
A: Maintaining a semi-Fowler's position may help with breathing comfort but does not directly address the issue of thick secretions.
B: Administering oxygen is important for COPD patients but does not specifically target bronchial secretions.
C: Selecting a low-salt diet is beneficial for managing fluid retention but does not directly address the issue of tenacious bronchial secretions.
A post-anesthesia care unit nurse is caring for a client who is postoperative following a thoracotomy and lobectomy. Which of the following postoperative assessments should the nurse give the highest priority to?
- A. Arterial blood gases
- B. Urinary output
- C. Chest tube drainage
- D. Pain level
Correct Answer: A
Rationale: The correct answer is A: Arterial blood gases. This is the highest priority assessment for a client post-thoracotomy and lobectomy as it helps monitor the client's oxygenation status and acid-base balance, crucial after thoracic surgery. ABGs provide immediate information on the client's respiratory function, detecting any respiratory complications early on. The other options, B: Urinary output, C: Chest tube drainage, and D: Pain level, are important assessments but not as critical as monitoring the client's oxygenation status post-thoracic surgery. Urinary output is important for renal function, chest tube drainage for monitoring for any bleeding or air leakage, and pain level for comfort, but none of these directly assess the client's respiratory status and potential complications.
A healthcare worker is caring for a group of clients in an infectious disease unit. The worker should wear an OSHA-approved N95 respirator mask when caring for a client with which of the following infectious diseases?
- A. Pertussis
- B. Mycoplasma pneumonia
- C. Tuberculosis
- D. Respiratory syncytial virus
Correct Answer: C
Rationale: The correct answer is C: Tuberculosis. Healthcare workers should wear an N95 respirator mask when caring for clients with airborne infectious diseases like tuberculosis. The N95 mask is designed to filter out at least 95% of airborne particles, including those that may carry the tuberculosis bacteria. This level of protection is necessary to prevent the healthcare worker from inhaling the infectious agent.
Pertussis (A), Mycoplasma pneumonia (B), and Respiratory syncytial virus (D) are not typically transmitted through the air and therefore do not require the use of an N95 respirator mask for standard care. These diseases are usually spread through respiratory droplets or direct contact, so standard precautions such as wearing a surgical mask and gloves are sufficient.
Appropriate treatment for a patient with cellulitis includes
- A. Petrolatum and vitamin A and D ointment.
- B. Antibiotics, such as cephalexin, and over-the-counter analgesics.
- C. Weight-bearing exercises and diuretics, such as furosemide.
- D. Wet to dry dressings and steroids.
Correct Answer: B
Rationale: Antibiotics are the mainstay of treatment for cellulitis.

- A. You are lying too long on the affected side.
- B. This is in response to your medication.

- D. This is secondary to dysphagia.
Correct Answer: C
Rationale: Guillain-Barré syndrome damages the myelin sheath, leading to abnormal sensations.
