A nurse is teaching a client about possible complications and hazards of home oxygen therapy. About which complications doesn't the nurse plan to teach the client?
- A. Absorptive atelectasis
- B. Combustion
- C. Dried mucous membranes
- D. Alveolar recruitment
Correct Answer: D
Rationale: The correct answer is D - Alveolar recruitment. This is because alveolar recruitment is actually a benefit of home oxygen therapy, not a complication. It helps improve oxygenation by opening up collapsed alveoli.
A - Absorptive atelectasis is a potential complication where nitrogen is absorbed from the alveoli leading to collapse. B - Combustion is a hazard due to oxygen's flammability. C - Dried mucous membranes is a common complication of oxygen therapy due to the drying effect of oxygen.

When teaching a patient with heart failure on a 2000-mg sodium diet. Which foods should the nurse recommend limiting?
- A. Chicken
- B. Fresh spinach
- C. Eggs
- D. Milk
Correct Answer: D
Rationale: The correct answer is D: Milk. Milk is a high sodium food and can contribute significantly to a patient's daily sodium intake. For a patient on a 2000-mg sodium diet, it is crucial to limit high sodium foods like milk to prevent fluid retention and worsening of heart failure symptoms. Other choices (A, B, C) are lower in sodium compared to milk. Chicken, fresh spinach, and eggs are generally good protein sources with lower sodium content and can be included in moderation in a 2000-mg sodium diet for a heart failure patient.
What is the best action for the nurse to do?
- A. a. Leave the patient alone to rest in a quiet, calm environment.
- B. b. Stay with the patient and encourage slow, pursed lip breathing.
- C. c. Reassure the patient that the attack can be controlled with treatment.
- D. Let the patient know that frequent monitoring is being done using measurement of vital signs and SpO. 2
Correct Answer: B
Rationale: The best action for the nurse to do is to stay with the patient and encourage slow, pursed lip breathing. This helps the patient focus on their breathing and can help alleviate the asthma attack symptoms.
A nurse is assessing a client who is recovering from a lung biopsy. The client's breath sounds are absent. While another nurse calls the Rapid Response Team
- A. what action by the nurse takes is most important?
- B. Take a full set of vital signs.
- C. Obtain pulse oximetry reading.
- D. Ask the patient about hemoptysis.
Correct Answer: B
Rationale: The correct answer is B, taking a full set of vital signs, as it is crucial in assessing the client's overall condition and detecting any signs of deterioration. Vital signs include blood pressure, heart rate, respiratory rate, and temperature, which provide valuable information about the client's cardiovascular and respiratory status. In this scenario, absent breath sounds indicate potential respiratory compromise, making it essential to monitor vital signs for any signs of respiratory distress or instability.
Choice A is incorrect because calling the Rapid Response Team is important, but assessing the client's vital signs should take priority to provide immediate information on the client's condition. Choice C, obtaining pulse oximetry reading, is also important but may not provide a comprehensive assessment of the client's overall condition compared to a full set of vital signs. Choice D, asking about hemoptysis, is not the most urgent action to take in this situation as assessing vital signs would provide more immediate and critical information for the client's management.
What is the function of the conchae in the nasal cavity?
- A. increase surface area
- B. exchange gases
- C. maintain surface tension
- D. maintain air pressure
Correct Answer: A
Rationale: The function of the conchae in the nasal cavity is to increase surface area. By increasing the surface area of the nasal cavity, conchae help to humidify, filter, and warm the air entering the respiratory system. This ensures optimal conditions for efficient gas exchange in the lungs. Choice B (exchange gases) is incorrect because gas exchange primarily occurs in the alveoli of the lungs, not in the nasal cavity. Choice C (maintain surface tension) is incorrect as surface tension is typically associated with liquid interfaces, not with the nasal cavity. Choice D (maintain air pressure) is also incorrect because the conchae do not play a direct role in maintaining air pressure within the nasal cavity.
which component of pharynx received the Eustachian tube
- A. oropharynx
- B. laryngopharynx
- C. Nasopharynx
- D. none of these
Correct Answer: C
Rationale: The correct answer is C: Nasopharynx. The Eustachian tube connects the middle ear to the nasopharynx, allowing for pressure equalization. The oropharynx (A) and laryngopharynx (B) do not directly receive the Eustachian tube. Choice D is incorrect as the Eustachian tube does connect to a specific part of the pharynx.
