Question 1 of 5
The client with COPD tells the nursing assistant that she did not get her annual flu shot this year and has not had a pneumonia vaccination. You will be sure to instruct the nursing assistant to report which of the following?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
What does the nurse include when planning for postural drainage for the patient with COPD?

Question 3 of 5
Residual volume of the lung is
Correct Answer: A
Rationale: The correct answer is A: 1200 ml. Residual volume is the amount of air left in the lungs after maximum expiration. It is around 1200 ml because it cannot be exhaled due to lung elasticity. Choice B (1500 ml) is incorrect as it is higher than the normal range. Choice C (4500 ml) is incorrect as it is too high for residual volume. Choice D (500 ml) is incorrect as it is too low for residual volume.
Question 4 of 5
Foetal hemoglobin has great affinity than adult hemoglobin because
Correct Answer: A
Rationale: The correct answer is A because 2,3 DPG binds less avidly to the Gamma polypeptide chain in foetal hemoglobin, resulting in a higher affinity for oxygen. This is due to structural differences between foetal and adult hemoglobin. Choice B is incorrect as high concentration alone does not determine affinity. Choice C is incorrect as the source of oxygen does not affect hemoglobin's affinity. Choice D is incorrect as the speed of oxygen binding does not necessarily correlate with affinity.
Question 5 of 5
Cloacal respiration is found in
Correct Answer: B
Rationale: Cloacal respiration is found in turtles and tortoises. These reptiles can absorb oxygen through their cloaca, a multi-functional opening used for excretion and reproduction. Turtles and tortoises lack specialized respiratory organs like lungs, and thus utilize cloacal respiration as an additional means of obtaining oxygen. Snakes (Option A) primarily rely on lung respiration. Crocodiles (Option C) have well-developed lungs for breathing. Frogs (Option D) respire through their skin and lungs but do not utilize cloacal respiration like turtles and tortoises. Therefore, the correct answer is B, as it is the only species listed that exhibits cloacal respiration.
