Nokea
Asphyxia occurs due to
- A. Rise in level of CO2
- B. Fall in level of CO2
- C. Rise of O2 level
- D. Fall in O2 level
Correct Answer: A
Rationale: The correct answer is A: Rise in level of CO2. Asphyxia occurs when there is a buildup of carbon dioxide (CO2) in the body, leading to a lack of oxygen supply to tissues. When CO2 levels rise, it can displace oxygen in the bloodstream, causing respiratory distress and potential suffocation. Choices B, C, and D are incorrect because a fall in CO2 levels, a rise in O2 levels, or a fall in O2 levels do not directly cause asphyxia. This highlights the importance of understanding the physiological processes involved in respiration to identify the correct answer.

A long-term COPD client is receiving oxygen at 1 L/minute. Her visiting cousin decides she "doesn't look too good" and increases her oxygen to 7 L/minute. What should the nurse's initial action be?
- A. Thank the client's cousin and continue to observe the client.
- B. Immediately decrease the oxygen.
- C. Notify the physician.
- D. Elevate the client's head and take vital signs.
Correct Answer: B
Rationale: The correct answer is B: Immediately decrease the oxygen. Increasing oxygen without physician's order can lead to oxygen toxicity in COPD patients. Step-by-step rationale: 1. Assess the client's condition. 2. Determine the client's baseline oxygen therapy. 3. Recognize that sudden increase in oxygen can suppress the respiratory drive in COPD patients. 4. Decrease oxygen to the prescribed level. Summary: A: Inadequate response, as oxygen adjustment is necessary. C: Not immediate action, physician notification can follow. D: Pertinent to assess, but not the initial action needed in this scenario.
The filtering and keeping the mucus and dirt away from our lung's performed by
- A. cilia
- B. bronchioles
- C. hair in lungs
- D. all of the above
Correct Answer: A
Rationale: The correct answer is A: cilia. Cilia are tiny hair-like structures in the respiratory tract that sweep mucus and dirt out of the lungs to keep them clean. Bronchioles are small airways in the lungs through which air passes, not involved in filtering. Hair in the lungs is not a natural structure; it would be harmful. Choice D is incorrect because not all options listed are involved in filtering and keeping the mucus and dirt away from the lungs.
A 92-year-old female patient is being admitted to the emergency department with severe shortness of breath. Being aware of the patient’s condition, what approach should the nurse use to assess the patient’s lungs?
- A. Apex to base
- B. Base to apex
- C. Lateral sequence
- D. Anterior then posterior
Correct Answer: D
Rationale: In a patient with severe shortness of breath, the nurse should assess the lungs using a posterior to anterior approach to minimize discomfort and optimize assessment in compromised patients.
Which statement by a patient with newly diagnosed heart failure indicates to the nurse that the teaching was effective?
- A. I will call the clinic if my weight goes up 3 pounds in a week.
- B. I will take furosemide (Lasix) every day just before bedtime.
- C. I will use the nitroglycerin patch whenever I have chest pain.
- D. I will weigh myself every week with the same scale.
Correct Answer: A
Rationale: The correct answer is A because it demonstrates understanding of monitoring for fluid retention, a common issue in heart failure. Calling the clinic if weight increases by 3 pounds in a week allows for early intervention. Choice B is incorrect because taking furosemide at bedtime may disrupt sleep and increase nighttime urination. Choice C is incorrect as nitroglycerin is for acute chest pain, not a preventative measure. Choice D is incorrect because weighing weekly may not catch sudden weight changes that indicate worsening heart failure.
While assisting a patient with intermittent asthma to identify specific triggers of asthma, what should the nurse explain?
- A. a. Food and drug allergies do not manifest in respiratory symptoms.
- B. b. Exercise-induced asthma is seen only in individuals with sensitivity to cold air.
- C. c. Asthma attacks are psychogenic in origin and can be controlled with relaxation techniques.
- D. d. Viral upper respiratory infections are a common precipitating factor in acute asthma attacks.
Correct Answer: d
Rationale: The correct answer is D because viral upper respiratory infections are a common precipitating factor in acute asthma attacks. This is important information for the patient to understand in order to help identify triggers and manage their asthma effectively. Viral infections can exacerbate asthma symptoms, so recognizing this connection can aid in prevention and treatment.
