Asphyxia occurs due to

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.

Correct Answer: B

Rationale: The correct answer is B: Do you have any chronic breathing problems? This question is appropriate because equal AP and lateral chest diameters could indicate barrel chest, which is often associated with chronic obstructive pulmonary disease (COPD) or other chronic breathing problems. Asking about chronic breathing problems can help the nurse further assess the client's respiratory health. Incorrect answers: A: Are you taking any medications or herbal supplements? This question is not directly related to the observed chest diameter findings. C: How often do you perform aerobic exercise? This question is not relevant to the physical assessment findings and does not address the potential respiratory issue. D: What is your occupation and what are your hobbies? This question does not directly address the equal AP and lateral chest diameters and does not help in assessing the respiratory status of the client.

Correct Answer: C

Rationale: The correct answer is C. Hydration is not directly related to tracheostomy care. The rationale is: A) Cognition is important for understanding and following care instructions. B) Dexterity is needed for handling tracheostomy equipment. C) Hydration, while important for overall health, does not directly impact tracheostomy care. D) Range of motion is relevant to prevent complications like skin breakdown. In summary, hydration is not a crucial factor to assess specifically for tracheostomy care compared to cognition, dexterity, and range of motion.

Correct Answer: D

Rationale: The correct answer is D: What is your occupation? This is the most important question because inhalation anthrax is commonly associated with certain occupations, like handling animal products or working in agricultural settings. Knowing the client's occupation can help identify potential sources of exposure. A: Are any family members also ill? - While important for assessing potential spread of infection, this question does not directly help in determining the cause of the anthrax infection. B: Have you traveled recently? - Travel history is relevant for certain infectious diseases, but for inhalation anthrax, occupational exposure is a more crucial factor to consider. C: How long have you been ill? - Timing of symptoms is important for diagnosis and treatment, but knowing the client's occupation provides more specific information in the case of suspected inhalation anthrax.

Correct Answer: B

Rationale: The correct answer is B. Persistent hoarseness is a hallmark symptom of laryngeal cancer. A (bacterial infection) may cause temporary hoarseness but not persistent. C (aphonia) refers to complete loss of voice, not hoarseness. D (peritonsillar abscess) affects the throat but does not typically cause persistent hoarseness.
