When assessing a client who gave birth 12 hours ago, the nurse measures an oral temperature of 99.6° f (37.5° c), a heart rate of 82 beats/minute, a respiratory rate of 18 breaths/minute, and a blood pressure of 116/70 mm hg. which nursing action is most appropriate?

Answers

The nursing action appropriate for this kind of case is encouraging increased fluid intake

The rationale behind this is that around the first day of postpartum, slight dehydration usually causes a slightly elevated temperature; the nurse should also encourage increased fluid intake to counter dehydration. Aspirin is contraindicated in postpartum clients because its anticoagulant effects may induce the risk of hemorrhage. Reassessment in vital signs every 4 hours is sufficient to evaluate the effectiveness of hydration measures. If the patient’s oral temperature exceeds 38 degrees Celsius or 100.4 degrees Fahrenheit, the nurse should request an antibiotic order since this may suggest an infection.

(b)The granite is older than the sandstone.

(c)The sandstone and granite are the same age.

(d)The granite is younger than the sandstone

Answers

Answer to Q1:

(d) by finding the absolute age of the rock

Explanation:

The relative age of a rock is not an exact number or age; rather it's the comparison of one rock or fossil to another to determine which one is older or younger. Scientists use carbon dating to calculate the age of a rock. Organic material from the rock is tested and that information is used to calculate the estimated age.


Answer to Q2:

C) Rock layers

Explanation:

The Fossil Record and Geologic Time Fossils of plants and animals are present in some rocks. These fossils contribute to our understanding of geologic time and they show us the time span when and how a civilization used to live.

Answer to Q3:

(c) They get a sense of the history of the area they are investigating.

Explanation:

Fossils scaled into rocks are fundamental to the geologic time scale. For instance rocks formed during the Proterozoic Eon may have fossils of relative simple organisms, such as bacteria, algae, and wormlike animals while Rocks formed during the Phanerozoic Eon may have fossils of complex animals and plants such as dinosaurs, mammals, and trees.  

Answer to Q4:

(a)the appearance and disappearance of groups of organisms

Explanation:

the appearance and disappearance of groups of organisms in different geological eras of earth history shows the time span of that era. This time span can be easily determined from the fossils present on sedimentary rocks because they show the family or group of those species which were present in that particular time period.

Answer to Q5:

(d)radioactive dating

Explanation:

Scientists use radioactivity techniques to determine the age of earth. As we know radioactive substances emit energy continuously and they have a certain half life period so calculating the half life period can show us the age of earth by comparing the half lives of different radioactive elements. For example in uranium-lead dating, for instance, the radioactive decay of uranium into lead proceeds at a reliable rate.

Answer to Q6:

(c)Sedimentary

Explanation:

Mostly sedimentary rocks like limestone and shale are the best options in the formation of fossils. Igneous rocks are formed directly from hot lava that is why they would not be able to preserve any remnants of living organisms that fall in it during its formation.

Answer to Q7:

The granite is older than the sandstone.

Explanation:

The principle of inclusions states that with sedimentary rocks, if inclusions  are found in a formation, then the inclusions must be older than the formation that contains them. So in simple words pieces of the older rock will be included in the younger rock therefore option B is the correct answer.

Stimulation of the vagus nerve in the baroreceptor reflex causes __________.

Answers

After the baroreceptor detect low blood pressure, there is a sympathetic activation, by the brain, of the vagal nerve causing vasodilation of veins and arterioles, decreased of heart rate and strength of contraction of the heart.
A sympathetic activation and a  parasympathetic inhibition allows the baroreflex to elevate blood pressure.

The stimulation of the vagus nerve in the baroreceptor reflex leads to parasympathetic stimulation, which decreases heart rate and cardiac output to help lower high blood pressure and maintain vascular homeostasis.

The baroreceptor reflex is a critical component of the body's ability to maintain vascular homeostasis. When blood pressure rises too high, the baroreceptors increase their firing rate, leading to parasympathetic stimulation of the vagus nerve, which slows the heart. Conversely, when blood pressure becomes too low, the rate of baroreceptor firing decreases, prompting an increase in sympathetic stimulation and a reduction in parasympathetic tone to raise the heart rate and blood pressure.

In contrast to cooperative hunting, which are benefits of herding only? Check all that apply. foraging reproduction divison of labor protection aerodynamic efficiency hydrodynamic efficiency

Answers

The answer to this question would be: foraging and protection 

Cooperative hunting needs a big amount of number. It also poses a danger to the member as the animal you hunt can fight back. If you only herding, the amount of the people can be used for foraging or even protecting the worker. 

Division of labor can be done in hunting too. Aerodynamic and hydrodynamic efficiency is used when bird or fish doing the migration. Their formation can make less energy used when moving in big number compared to when they moving alone.
Final answer:

OPTION A, B, C.

The benefits of herding as opposed to cooperative hunting include efficient foraging, increased protection, and division of labor among the herd members, all of which contribute to survival and sustenance of the group.

Explanation:

In contrast to cooperative hunting, there are distinct benefits for animals living in herding societies. The key benefits of herding include foraging, protection, and division of labor.

Foraging becomes more efficient in herds. Animals can cover larger areas and gather food resources more swiftly and with reduced risks. This gathering of food resource is often guided by the herding society's knowledge about their environment, vegetation, and water sources.  

The protection element is a crucial advantage of herd living. Members of a herd can look out for one another and provide greater defense against predators. This is especially notable in 'clumped' population distributions, where the safety of individuals is improved within the group structure.

Last but not least, division of labor is another crucial benefit. Tasks within the herd can be distributed among different members, creating a more balanced and efficient system. This includes aspects like taking care of young ones, sourcing food, or even roles in herd defense.

The answers would be "can be small", "can be large", and "have nonliving parts". This is 100% correct, because I got it right on my lesson.

Answer:

The answers are:

- Can be small

- Can be large

- Have nonliving parts

Explanation:

An ecosystem is a biological system constituted by a community of living organisms and the physical environment where they are related (that is, it is composed of both living and non-living parts). It is a unit composed of interdependent organisms that share the same habitat. A biome is made up of many similar ecosystems, so an ecosystem is much smaller than a biome, although the size of the ecosystems can vary (they can be large or they can be small).

When the cell excretes sodium from within, against the natural tendency of matter, it is performing _____.

passive diffusion
facilitated diffusion
active transport
pinocytosis

Answers

It is active transport the chain is called the sodium ion pump

When the cell excretes sodium from within, against the natural tendency of matter, it is performing active transport.

In active transport the molecules move across a membrane from the region of lower concentration to a region of higher concentration using the cellular energy for the motion against the concentration gradient.

The cell excreting sodium from within is a part of the sodium potassium pump. In sodium-potassium pump the sodium ions are transported from inside the cell to outside  actively although the concentration of sodium is higher outside the cell. The energy which is used to transport sodium from inside to outside and potassium from outside to inside both against the concentration gradient is obtained through the breakdown of the ATP molecule.
