After change of shift, you are assigned to care for the following clients. Which client should you assess first?

Correct Answer: D

Rationale: In this scenario, the correct answer is D) A 51-year-old client with asthma complaining of shortness of breath (SOB) after using a bronchodilator inhaler. This client should be assessed first because sudden shortness of breath in an asthmatic patient could be a sign of impending respiratory distress, requiring immediate intervention. Option A, the 68-year-old on a ventilator needing a sputum specimen, can be prioritized after addressing the acute respiratory distress of the asthma patient. Option B, the COPD patient with a pulse oximetry reading of 90%, requires monitoring and intervention but is not currently experiencing acute distress. Option C, the client with pneumonia needing IV antibiotics, is important but not as urgent as the asthma patient with acute shortness of breath. This educational context emphasizes the importance of prioritizing patient care based on the urgency of the situation. Recognizing and responding promptly to acute changes in respiratory status is crucial in preventing respiratory compromise and potential deterioration in patients with respiratory conditions.

Correct Answer: A

Rationale: Assisting the patient to get out of bed can be safely delegated to unlicensed assistive personnel (UAP) as it does not require specialized nursing knowledge or skills. It is a basic activity of daily living that can be delegated to support staff while allowing nurses to focus on more complex patient care tasks.

Correct Answer: C

Rationale: Step 1: Chlorocruorin contains copper, giving it a green color. Step 2: In oxygenated state, chlorocruorin appears green due to the presence of copper. Step 3: In deoxygenated state, chlorocruorin retains its green color. Step 4: Therefore, the correct answer is C: Green. Summary: A (Blue) and B (Red) are incorrect as chlorocruorin is green due to copper. D (Blue red) is incorrect as it does not reflect the true color of chlorocruorin.

Correct Answer: B

Rationale: The correct answer is B because 2,3 DPG binds to the Beta chain of Hemoglobin, reducing its oxygen affinity, causing a right shift in the Oxygen dissociation curve. This change allows for easier oxygen unloading in tissues. Choice A is incorrect as 2,3 DPG decreases, not increases, oxygen affinity. Choice C is irrelevant as its concentration is not a factor in the shifting of the curve. Choice D is incorrect as 2,3 DPG does bind to Hemoglobin, specifically to the Beta chain.

Correct Answer: B

Rationale: In this multiple-choice question on the respiratory system, the correct answer is option B) Nepa (Water boatman). The plastron is an air bubble that aquatic insects use to carry respiratory air in their abdomen. Water boatmen, such as Nepa, have specialized structures that allow them to trap and carry this bubble of air, enabling them to respire while submerged in water. Option A) Belostoma is incorrect because Belostoma species do not use a plastron for respiration. Instead, they rely on other mechanisms for breathing underwater. Option C) Chironomous and option D) Mosquito are also incorrect as these insects do not possess the specialized adaptations for carrying an air bubble like the water boatman does. Educationally, understanding the respiratory adaptations of aquatic insects like the water boatman provides insight into the diverse strategies organisms have evolved to survive in different environments. This knowledge is crucial in the fields of biology and ecology, shedding light on the interconnectedness of organisms and their habitats.
