Respiratory System Questions Questions
Question 1 of 5
Which of the following gases makes the most stable combination with the haemoglobin of red blood cells
Correct Answer: B
Rationale: The correct answer is B: CO. Carbon monoxide (CO) forms a stable combination with hemoglobin, known as carboxyhemoglobin. This is because CO has a higher affinity for hemoglobin than oxygen (choice C), leading to the formation of a stable bond. Choice A (CO2) forms a reversible combination with hemoglobin, while choice D (N) does not bind significantly to hemoglobin. Hence, B is the most stable combination due to CO's strong bond with hemoglobin.
Question 2 of 5
A nurse teaches a client to use a room humidifier after a laryngectomy. Which statement would the nurse include in this patient's teaching?
Correct Answer: B
Rationale: The correct answer is B: Make sure you clean the humidifier to prevent infection. This is important because a dirty humidifier can harbor bacteria and mold, leading to respiratory infections in a laryngectomy patient who is already at a higher risk of respiratory complications. Cleaning the humidifier regularly helps maintain a safe and healthy environment for the patient. Incorrect choices: A: Adding peppermint oil can irritate the airway and is not recommended for laryngectomy patients. C: Keeping the humidifier filled with water at all times can lead to bacterial growth if the water is not changed regularly. D: Using the humidifier constantly can lead to over-humidification, which can also increase the risk of respiratory infections.
Question 3 of 5
During the physical examination of a client, which of the following methods does the examiner use to palpate for tactile or vocal fremitus?
Correct Answer: A
Rationale: The correct answer is A. Tactile or vocal fremitus is assessed by placing the palms of the hands or the ulnar surface of the fingers on the chest wall while asking the patient to say 'ninety-nine' or '11'. This method allows the examiner to feel vibrations transmitted through the lung tissue. B is incorrect because repeating '11' is part of auscultation, not palpation. C refers to percussion, which is unrelated. D is incorrect as no vibrations are observed when the client remains quiet.
