The nurse has instructed the client on how to obtain a sputum culture. Which of the statements indicates that the client understood the instruction from the nurse?
- A. I need to restrict my fluids 8 hours before obtaining the specimen.
- B. Mouth care should be avoided before collecting the sputum specimen.
- C. The best time to obtain the specimen is late at night.
- D. I just need to breathe deeply, followed by coughing up the sputum.
Correct Answer: D
Rationale: The correct answer is D because the client demonstrates understanding by acknowledging the need to breathe deeply and cough up the sputum to obtain a sputum culture. This action helps bring up the lower respiratory tract secretions for an accurate culture. Choice A is incorrect because increasing fluids actually helps in sputum production. Choice B is incorrect as mouth care should be done before to prevent contamination. Choice C is incorrect as early morning is the best time due to the accumulation of secretions overnight.

Muscles attached to diaphragm contract during inspiration to make it
- A. Flat
- B. Dome-shaped
- C. Concave
- D. Rotate
Correct Answer: A
Rationale: The correct answer is A: Flat. During inspiration, the muscles attached to the diaphragm contract, causing it to flatten. This action increases the volume of the thoracic cavity, allowing air to rush into the lungs. The diaphragm moving downward creates a larger space for the lungs to expand. Choices B, C, and D are incorrect because the diaphragm does not become dome-shaped, concave, or rotate during inspiration. The key concept here is understanding the role of the diaphragm in the breathing process and how its contraction affects the shape of the thoracic cavity.
The left lung has two lobes and they are separated by Deep fissure called .
- A. horizontal fissure
- B. oblique fissure
- C. Vertical fissure
- D. non of them
Correct Answer: B
Rationale: The correct answer is B: oblique fissure. The left lung has two lobes, the upper lobe and the lower lobe, which are separated by the oblique fissure. This fissure extends obliquely downward and forward from the posterior border of the lung.
Rationale:
1. The horizontal fissure separates the right lung into upper and middle lobes, not the left lung.
2. There is no such structure as a vertical fissure in the human lung anatomy.
3. "Non of them" is grammatically incorrect and does not provide a valid option.
A nurse in a family practice clinic is preparing discharge instructions for a client reporting facial pain that is worse when bending over tenderness across the cheeks and postnasal discharge. What instruction will be most helpful?
- A. Ice packs may help with the facial pain.
- B. Limit fluids to dry out your sinuses.
- C. Try warm, moist heat packs on your face.
- D. We will schedule a computed tomography scan this week.
Correct Answer: C
Rationale: The correct answer is C: Try warm, moist heat packs on your face. Warm, moist heat can help relieve facial pain and sinus pressure by promoting sinus drainage and reducing inflammation. Ice packs may not be as effective for this type of pain. Limiting fluids can worsen symptoms by drying out the sinuses. Scheduling a CT scan is not necessary at this point as the symptoms described are indicative of sinusitis, which can often be managed with conservative measures like warm compresses.
What dietary recommendation is often given to heart failure patients to manage their condition?
- A. High-sodium diet
- B. Low-fat diet
- C. Low-sugar diet
- D. Low-sodium diet
Correct Answer: D
Rationale: The correct answer is D: Low-sodium diet. Sodium can exacerbate fluid retention in heart failure patients, leading to increased workload on the heart. A low-sodium diet helps reduce fluid retention and manage symptoms. High-sodium diet (A) is detrimental to heart failure patients. Low-fat diet (B) and low-sugar diet (C) may be beneficial for overall health but are not specific recommendations for managing heart failure.
A nurse is caring for a male client with emphysema who is receiving oxygen. The nurse assesses the oxygen flow rate to ensure that it does not exceed:
- A. 1 L/min
- B. 2 L/min
- C. 6 L/min
- D. 10 L/min
Correct Answer: B
Rationale: The correct answer is B: 2 L/min. The rationale is that in emphysema, high oxygen flow rates can cause oxygen toxicity. The recommended maximum flow rate for patients with emphysema is typically 2 L/min to prevent oxygen toxicity. Choice A (1 L/min) may not provide sufficient oxygen, choice C (6 L/min) and choice D (10 L/min) are too high and can lead to oxygen toxicity in patients with emphysema. Therefore, choice B is the most appropriate and safe option for this client.
