The nurse is assessing the client's readiness for discharge from the postanesthesia care unit (pacu). the nurse can rouse the client by calling the client's name. the client can move all extremities and has a blood pressure of 134/82. baseline preoperative blood pressure was 128/78. the most recent pulse oximetry reading was 94% on room air; the client's respirations are deep and easy at a rate of 12/minute. the nurse calculates the aldrete score as:

The answer would be 9

Blood pressure: 2
for less than 10 increase from base BP
Activity: 2
for moves all extremity voluntary
Respiration : 2
for breath deeply and easily
Saturation: 2
for >92% SaO
Consiousness: 1
for arousable on calling. "The nurse can rouse the client by calling the client's name"

Other than the consciousness, the patient got 2 scores. So, the total score would be 9/10

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
