Which might be considered a limiting factor to the amount fish in a lake *
PilotLPTM [1.2K]

Answer:

D). Choice 2 and 3

Explanation:

Given the options above, the limiting factors are both the "Amount of water in the lake" and the "Temperature of the lake"

This is because the amount of water in the lake can only carry as much of the number of fishes as possible it can contain or sustain. This implies that the higher the water content in the lake the higher the number of fishes it can contain and vice versa.

Also, the temperature of the lake is a limiting factor because the temperature of the lake supports the light penetration to the fishes in the water. Should the temperature increases beyond the highest level the water can support, the fishes will die.

henke vg, bateman bt, leffert lr. focused review: spinal anesthesia in severe pre-eclampsia. anesth analg. 2013 sep;117(3):686-9
stira [4]

A form of neuraxial anesthesia known as spinal anesthesia involves injecting local anesthetic (LA) into the cerebrospinal fluid (CSF) of the lumbar spine in order to numb the nerves that leave the spinal cord.

<h3>What does the study indicate?</h3>
  • As long as there is no indwelling epidural catheter or neuraxial anesthesia contraindication, spinal anesthesia is generally regarded as a reasonable anesthetic choice for cesarean delivery in severe preeclampsia.
  • Those with severe preeclampsia experience spinal-induced hypotension less frequently and with less severity than healthy parturients.
  • Although spinal anesthetic may result in more hypotension than epidural anesthesia in cases of severe preeclampsia, this hypotension is often manageable, transient, and unrelated to clinically meaningful differences in outcomes.
