The father of a newly delivered full-term newborn is observing admission of the infant to the nursery. He asks the nursing student performing the admission why a cover is being placed on the baby scale to weigh and measure the newborn

First let's add the missing piece of information for clarity and then the options before we write the answer

The response that the nursing student should make is based on understanding the mechanism of heat loss in the newborn. This nursing intervention is designed to protect the newborn against which heat loss mechanism?

The options:

1. Radiation

2. Convection

3. Conduction

4. Evaporation

The CORRECT ANSWER IS 3.

3. Conduction

Explanation:

Thermoregulation in humans is a major area of homeostasis. In thermoregulation, body heat is produced mainly in the vital organs, such as the liver, brain, and heart, and in skeletal muscles contracting activities.

There are basically four modes of heat loss: convection, conduction, radiation, and evaporation.

Heat loss by radiation and conduction occurs when the skin temperature is higher in comparison to the surroundings temperature.

Heat loss by evaporation occurs when the surroundings temperature is higher in comparison to the skin temperature as in sport activity.

Back to our case study:

1. Radiation❌

Radiation is seen when the body or skin lossses heat to a cooler body without any direct contact being made.

2. Convection❌

Convention is seen when the body or skin losses heat to cooler ambient air.

3. Conduction✔✔✔

Conduction is seen when the body or skin comes in direct contact with a cooler surface resulting in a loss of body heat.

4. Evaporation❌

Evaporation is a phenomenal that results in heat loss in the process of converting liquid to a gas.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
