Tachycardia, decreased or absent breath sounds on the affected side, hyperresonance, and sudden chest pain on the affected side are clinical manifestations of:__________
A) Sarcoidosis
B) Pneumothorax
C) Hypersensitivity pneumonitis
D) adult respiratory distress syndrome
Answer: Option B.
Pneumothorax
Explanation:
Pneumothorax occurs when air buildup between the chest wall and the lungs thereby leading to increased pressure in the chest and it inturn decrease the amount of blood that flow back to the heart because the blood find it difficult to force it's way into the chest and the heart. This is cause by injury to the chest, lung danage, rupture air blisters and mechanical ventilation.
The symptoms include decreased or absent breath sounds on the affected side, hyperresonance, and sudden chest pain on the affected side , racing heart, shock.
When a pneumothorax is large, a needle or tube is used to remove excess air.
During an intramuscular injection procedure, the medication label should be checked:
Answer:
The medication label should be checked by comparing it with the MAR (Medication Administration Records or therapeutic documentation care plan TDCP).That is the label printed on the medication should be compare with the Medication Administrations records
Explanation:
Ideally this should be done three times, when it is removed from the medication cart,and before and after it was removed form the medication cart.
Besides,the date of expiration should be checked,and the regulations concerning administrations of multi-does vial should be taken into considerations.
The medications mode of storage should be taken into confederation,proper storage must be ensured.
Generally the application of medication through injection into the muscles for faster absorption into the blood streams for fast distribution is called IM. This is aided by the rich blood supply to the muscles.Therefore it is a faster mode of blood application than the subcutaneous routes.

Explain why eating a meal with too much salt leads to production of small volume of concentrated urine.
Answer:
the urine is burned up by salt which will evaporate
Answer:
Eating a meal with too much salt leads to a decrease in the water potential of blood. This fall in water potential is detected by the osmoreceptors in the hypothalamus (in brain). The hypothalamus stimulates the pituitary gland to release antidiuretic hormone (ADH). The walls of the collecting duct in the kidney become more permeable to water, hence, a greater proportion of water is reabsorbed from the urine back into the blood by osmosis.
As a result, a small volume of concentrated urine is formed.

How many total kcalories has she taken in, and how many and what percentage of kcalories are from carbohydrate, protein, and fat?
A. Total kcalories:
B. Percentage of kcalories from carbohydrate:
C. Percentage of kcalories from protein:
D. Percentage of kcalories from fat:
Answer and Explanation:
The computation is shown below:
A. For Total k. calories
= (Number of grams in carbohydrates × 1 gm of carbohydrates) + (Number of grams in protein × 1 gm of proteins) + (number of grams in fat × 1 gm in fat)
= (500 × 4) + (30 × 4) + (75 × 9)
= 2000 + 120 + 675
= 2795 k. calories
b. As we know that
1 gm of carbohydrates = 4 k. calories
So, for 500 grams it would be
= 500 × 4
= 2000 k. calories
Now the percentage is
= Total grams in carbohydrates ÷ Total kcalories
= 2000 ÷ 2795
= 0.72
= 72%
C. As we know that
1 gm of proteins = 4 k. calories
So, for 40 grams, it would be
30 × 4 = 120 k. calories
Now the percentage is
= Total grams in protein ÷ Total kcalories
= 120 ÷ 2795
= 0.043
= 4.3%
D. As we know that
1 gm of fat = 9 k. calories
So for 75 grams, it would be
75 × 4 = 200 k. calories
So, the percentage is
= Total grams in fat ÷ Total kcalories
= 200 ÷ 2795
= 0.072
= 7.2%

In order for translation to occur: Please choose the correct answer from the following choices, and then select the submit answer button. transcription must be occurring simultaneously. there must be large numbers of free amino acids present in the cytoplasm. the DNA must produce large numbers of free amino acids. replication must be occurring simultaneously. the nuclear membrane must first dissolve
Answer:
there must be large numbers of free amino acids present in the cytoplasm
Explanation:
In order for translation to occur, there must be a large number of free amino acids in the cytoplasm.
These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.
During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.
Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.

Assume that the point mutation and deletion mutation are not in overlapping regions of the phage genome. What phage recombinants would you expect if a crossing-over event occurred between the regions of the two mutations?
Answer:
A recombinant phage containing both mutations.
Explanation:
A recombinant organism is produced by recombination, which is a genetic phenomenon associated with the repair of double-strand breaks in DNA. In genetic research, recombinant organisms are used to investigate target gene expression. The process of DNA repair may be associated with two different pathways: homologous recombination (HR) and non-homologous end-joining (NHEJ). In this case, the recombinant phage contains no overlapping mutations (i.e., both deletion and point mutations), thereby carrying the desired genetic combination.
List some characteristics of each type of seismic wave. Include what type of material (solids, liquids, or both) each can travel through. Primary wave: Secondary wave: Love wave: Rayleigh wave:
Answer:
The primary wave or the P wave is the fastest kind of seismic wave. These waves can travel through the fluids like the liquid or the water layers of the Earth, and solids rocks. It pulls and pushes the rock it moves through similar to the sound waves that pull and pushes the air. These waves are also called compressional waves, due to the pulling and pushing they do.
The secondary wave is also known as the S wave is slower in comparison to a P wave, and possess the tendency to move through the solid rock, however, not through any kind of liquid medium. The characteristic of the S wave helped seismologists to conclude that the outer core of the Earth is a liquid. The S waves help in moving the particles of rock side to side perpendicular to the direction of the wave or up and down.
The Love wave and Rayleigh waves are the two kinds of surface waves. These waves possess lower frequency in comparison to the P and S waves. Of the surface waves, the Love waves are the fastest surface wave and move the ground from side to side.
On the other hand, a Rayleigh wave rolls around the ground similar to the rolling of the waves across an ocean or a lake. Both these waves only travel through a solid medium.

Which of the following is false? Unselected Under normal conditions, blood PO2 affects breathing only indirectly. Unselected Changes in arterial pH resulting from CO2 retention or metabolic factors act through the peripheral chemoreceptors. Unselected When arterial PO2 falls below 60 mm Hg, it becomes the major stimulus for respiration. Unselected Oxygen levels are the primary stimulant of respiration.
Answer:
The sentence that says: Blood PO2 affects respiration only indirectly, IT IS FALSE, since the partial pressure of oxygen gas together with carbon dioxide are factors that DIRECTLY affect respiration.
The sentence that says: Unselected changes in arterial pH as a result of CO2 retention or metabolic factors act through peripheral chemoreceptors. It is FALSE, since the central chemoreceptors together with the peripheral ones can detect the metabolic acidosis generated by the CO2 retention, this is how the CNS receptors capture the CO2 that crosses the blood-brain barrier and stimulates hyperventilation to compensate for this phenomenon and increase the plasma concentrations of partial oxygen pressures.
The sentence that says: in selecting When arterial PO2 falls below 60 mm Hg, it becomes the main stimulus for breathing, IT IS FALSE, since it not only encourages ventilation to promote oxygenation but also activates the renin-angiotensin-aldosterone in order to recover blood volume and thus achieve adequate blood pressure.
In addition, hypovolemia triggers tachycardia and weakening symptoms, which is why the drop in blood pressure is not the main stimulus for breathing.
Explanation:
Breathing is promoted by muscle contraction, medium and high temperatures (that is, in hot or hot climates), partial concentrations of oxygen and carbon dioxide both in the atmosphere and in our blood, and in situations of systemic imbalances such as metabolic acidosis or alkalosis.
