An adult with the diagnosis of schizophrenia is admitted to the psychiatric hospital. the client is ungroomed, appears to be hearing voices, is withdrawn, and has not spoken to anyone for several days. what should the nurse do during the first few hospital days

Answers

If an adult with the diagnosis of schizophrenia is admitted to the psychiatric hospital during the first few hospital days the nurse should seek out the client frequently in order to spend short periods of time together. Seeking out the client frequently to spend short periods of time together will help the nurse establish trust without increasing the person's anxiety. Seeing that the client bathes and changes clothes daily is not a priority unless the client is super and extremely dirty; this client is ungroomed, not dirty. A withdrawn client will usually not approach anyone and the client's history reveals a failure to speak.

The _______________ completely covers the surface of the protoplasm.

Answers

The plasma membrane completely covers the surface of the protoplasm.

The plasma membrane, or plasmalemma, is the structure that completely covers the surface of the protoplasm, serving as a protective barrier and regulating the passage of substances into and out of the cell.

The structure that completely covers the surface of the protoplasm is the plasma membrane, or plasmalemma. This membrane serves as a protective barrier that regulates the passage of substances into and out of the cell.

In some protozoans, a structure called the pellicle is present just inside the plasma membrane, providing additional rigidity.

Underneath the plasma membrane, ectoplasm and endoplasm form distinct layers of cytoplasm that contribute to complex cell shapes.

The cell wall is another structure described in plant, fungal, and some protistan cells; it is external to the plasma membrane and offers protection, support, and shape to the cell, but it is not the surface that covers the protoplasm in animal cells such as protozoans.

Instead, in protozoans, it's the plasma membrane that completely covers the protoplasm.

The Effect of Extreme pH on Catalase Function What are you looking for in your observations when you are looking for evidence of a reaction? Does the plant tissue that we tested contain catalase? Does the animal tissue that was tested contain catalase?

Answers

The answers are as follows:
1. YOU ARE LOOKING FOR OXYGEN BUBBLES AS EVIDENCE OF CHEMICAL REACTION.
Catalase is an enzyme which speed up the rate of decomposition of hydrogen peroxide to water and oxygen. So, in this reaction, which test for catalase activity, hydrogen and oxygen will be formed as products of the reaction. The oxygen gas formed will be in form of bubbles. Therefore when you observe bubbles in your test tube, that means that the reaction is taking place and the oxygen gas is been formed.

2. YES, THE PLANT TISSUE TESTED CONTAINS THE CATALASE ENZYME.
Catalase is an important enzyme in plant tissues. It is present in all plants that are exposed to oxygen. The catalase enzyme helps the plants to speed up the rate of decomposition of hydrogen peroxide that are produced in the plants as a result of metabolic reactions taking place in plants. 

3. YES, THE ANIMAL TISSUE THAT WAS TESTED CONTAINS THE CATALASE ENZYME.
Catalase is a very important enzyme that is found in the liver of all living organism. The liver always produce hydrogen peroxide as a result of its metabolic reactions. This hydrogen peroxide is very toxic to the liver cells and can destroy them completely if its concentration is high in the cells. The function of the catalase is to break down the hydrogen peroxide into water and oxygen immediately they are formed. Water and oxygen are not toxic to the cells. Thus, the catalase enzyme work to prevent the destruction of the liver cells in animals.

There are two types of muscles, voluntary and involuntary. In order to answer this question, you need to know the difference between the two. Voluntary muscles are ones that you can control. For example, by doing a push up or waving your arms around you are using your muscles voluntarily. In contrast, involuntary muscles are ones that you cannot control. You heart contains muscle tissue that cannot be controlled voluntarily. One example that illustrates the involuntary control of cardiac muscle tissue is the shortening in the bands of muscle in your heart, resulting in a decrease in chamber size, which then ejects blood to the pulmonary and systemic vessels.

Instead of oxygen, __________ may utilize nitrate or sulfate as their final electron acceptors

Answers

The answer to this question would be: obligate anaerobe

In anaerobic reaction, oxygen is not used. That is why anaerobic microbes can live without oxygen. But the energy that was produced by this reaction is much less than aerobic reaction. That is why a more complex organism more likely to be able to do the aerobic reaction.
Final answer:

Denitrifiers and other bacteria can use nitrate or sulfate as final electron acceptors in anaerobic respiration.

Explanation:

One possible alternative to aerobic respiration is anaerobic respiration, using an inorganic molecule other than oxygen as a final electron acceptor. Denitrifiers are important soil bacteria that use nitrate (NO3¯) and nitrite (NO₂¯) as final electron acceptors, producing nitrogen gas (N₂). Many aerobically respiring bacteria, including E. coli, switch to using nitrate as a final electron acceptor and producing nitrite when oxygen levels have been depleted.

If a person is severely dehydrated, their extracellular fluids will become hypertonic to the intracellular fluid. what do you predict will happen to the person's cells

Answers

In hypertonic condition, osmosis will occur. In this case, the fluid will be attracted into the hypertonic solution since it osmotic pressure is higher. This condition can cause the nearby cells losing their water molecule and become shrink.
If it happens for a long time, the concentration of molecule inside the cell will increase since the water is decreased. This will cause the cell undergo lysis.
Final answer:

In response to severe dehydration causing the extracellular fluid to become hypertonic, cells will lose water, causing them to shrink. This process is due to osmosis, which seeks to balance the solute concentrations inside and outside the cells. This can lead to dysfunction of the cells.

Explanation:

If a person is severely dehydrated, their extracellular fluids will become hypertonic to the intracellular fluid. This results in a higher concentration of solutes in the extracellular fluid when compared to the intracellular fluid. Given this hypertonic situation, water within the cells will move out to the extracellular environment in an attempt to balance the concentration of solutes, a process known as osmosis.

This movement of water out of the cells can lead to the cells shrinking or becoming dehydrated. In extreme cases, cells may cease to function normally and in severe cases this can be harmful or potentially fatal if not promptly addressed. Living organisms usually strive to maintain a state of isotonicity, where the solute concentration is the same in and outside of cells preventing such drastic movements of water.

The answer would be –genesis and –gram. 

Suffixes that have a Greek or Latin roots and that are used to combine with other words or parts of words are not called suffixes, these kind of affixes are called combining forms.


One combing form is –genesis.


As an independent medical term, this means the origin of something in medicine. When a doctor talks about the genesis of a contagion, he or she is speaking of the point of origin of a contagion.


-genesis used as a suffix, can indicate a particular process or pathogen. Example is parthenogenesis.


One combining form is –gram.
