Choose the types of sludge depending on the size of the aggregates of blood cells, the origin of their contours and packing density.

Question 80Answer

1.
resorptive


2.
amorphous


3.
dextran


4.
extravascular


5.
classic

In hematology, "sludge" refers to a colloidal suspension of blood cells that can occur in certain pathological conditions. Depending on the size of the aggregates of blood cells, the origin of their contours, and packing density, the types of sludge can be described as follows:

1. **Resorptive** - Typically denotes sludge that occurs in response to the absorption of fluids or substances, often noted in specific pathological states but not a standard classification of blood cell aggregates.

2. **Amorphous** - Refers to aggregates of cells that lack a definite shape or form, which is consistent with some types of sludge.

3. **Dextran** - A type of plasma expanders used in medicine; however, in the context of "sludge," it may refer to a type of aggregation that resembles or involves dextran, but this is not widely recognized as a classification for blood cell aggregates.

4. **Extravascular** - This term typically refers to blood components or aggregates occurring outside of the blood vessels, which is not specifically a classification of sludge related to blood cell aggregates in the conventional sense.

5. **Classic** - This could refer to well-defined or traditional forms of sludge that are regularly acknowledged in medical literature, often linked to conditions where blood viscosity is elevated.

Based on this understanding, the most relevant types of sludge depending on the context would likely be:

- **Amorphous** 
- **Classic**

The others either do not directly relate to the classification of blood sludge or are not typically categorized in that manner. Thus, for types of sludge based on the size of aggregates, their contours, and packing density, **2 (amorphous)** and **5 (classic)** are the most appropriate selections.

Choose the long-term compensation mechanisms of acid-base balance state.

Question 81Answer

1.
Protein buffer


2.
Hemoglobin buffer


3.
Ammoniogenesis


4.
Respiration (hyperventilation)


5.
An exchange of carbonic acid salts from bone tissue for H+

In the context of maintaining acid-base balance, long-term compensation mechanisms involve physiological processes that help stabilize blood pH over time. Here's an analysis of the options provided:

1. **Protein buffer** - While proteins can buffer changes in pH by binding or releasing hydrogen ions, they primarily play a role in short-term buffering rather than long-term compensation. 

2. **Hemoglobin buffer** - Hemoglobin does act as a buffer system in the blood, but it functions primarily in the immediate response to changes in pH rather than as a long-term mechanism.

3. **Ammoniogenesis** - This is a renal process where the kidneys produce ammonia to excrete excess hydrogen ions. This is indeed a long-term compensation mechanism for metabolic acidosis, as the kidneys regulate acid-base balance over time.

4. **Respiration (hyperventilation)** - Hyperventilation can lead to changes in blood pH and is more of an acute response rather than a long-term mechanism. Long-term changes in respiration occur, but hyperventilation itself is not a chronic compensatory mechanism.

5. **An exchange of carbonic acid salts from bone tissue for H+** - This process can occur over a longer timespan and contributes to maintaining acid-base balance by acting as a reservoir for hydrogen ions and assisting in buffering excess acidity.

Based on this analysis, the long-term compensation mechanisms of acid-base balance are:

- **3. Ammoniogenesis**
- **5. An exchange of carbonic acid salts from bone tissue for H+**

Thus, the correct answers are **3 and 5**.

Choose the types of edemas by its pathogenesis.

Question 82Answer

1.
Renal


2.
Oncotic


3.
Cardiac


4.
Cachexic


5.
Hydrodynamic

Edema can be classified based on its underlying causes or pathogenesis. Here are the options provided, analyzed for their relevance to the types of edema based on pathogenesis:

1. **Renal edema** - This type of edema occurs due to renal dysfunction, which can lead to sodium retention and increased fluid volume. It is linked to pathophysiological changes in the kidneys.

2. **Oncotic edema** - This type of edema is caused by a decrease in plasma oncotic pressure, often due to low albumin levels in conditions like liver disease, nephrotic syndrome, or malnutrition, leading to fluid leakage into the interstitial space.

3. **Cardiac edema** - This type occurs due to heart failure, where the heart is unable to pump effectively, leading to fluid accumulation in tissues (pulmonary or peripheral edema).

4. **Cachexic edema** - This type of edema can occur in individuals with cachexia (severe weight loss and muscle wasting), often due to underlying diseases such as cancer or chronic infections, where the loss of proteins contributes to fluid retention.

5. **Hydrodynamic edema** - This term is not commonly used in the classification of edema, but it could refer to edema caused by disturbances in hemodynamics and fluid balance, primarily due to changes in blood pressure or fluid dynamics in the circulation.

Based on these definitions, the types of edema by pathogenesis include:

- **1. Renal**
- **2. Oncotic**
- **3. Cardiac**
- **4. Cachexic**

Thus, the correct answers are **1, 2, 3, and 4.** While "hydrodynamic edema" is not a standard classification, the others represent clear forms of edema based on their pathogenesis.

Match the mechanisms of emergency adaptation to hypoxia with their examples:

An increase in cardiac output


An increase in alveolar
ventilation


An increase in the oxygen
capacity of the blood
Centralization of blood
circulation

Here’s the correct matching of the mechanisms of emergency adaptation to hypoxia with their examples:

1. **Blood system**  
   - **An increase in the oxygen capacity of the blood**  
     This adaptation occurs primarily by increasing the hemoglobin concentration or improving the oxygen-carrying efficiency of hemoglobin.

2. **External respiration system**  
   - **An increase in alveolar ventilation**  
     This mechanism involves increasing the rate and depth of breathing to enhance oxygen uptake and carbon dioxide removal in the lungs.

3. **Vascular system**  
   - **An increase in cardiac output**  
     This refers to the heart's ability to pump more blood, thereby delivering more oxygen to tissues and improving circulation due to increased stroke volume or heart rate.

4. **Centralization of blood circulation**  
   - **This can be an additional matching example where blood flow is redirected to vital organs (like the brain and heart) at the expense of less critical areas, but it does not specifically relate to the other options.**

So the final matchings would be:
- **Blood system:** **An increase in the oxygen capacity of the blood**
- **External respiration system:** **An increase in alveolar ventilation**
- **Vascular system:** **An increase in cardiac output** 

This should provide clarity and accuracy in the context of adaptations to hypoxia.

Name of the scientist who formulated the triad of conditions for thrombus formation.

The scientist who formulated the triad of conditions for thrombus formation is **Heinrich Wilhelm Waldeyer**. However, the triad itself is often attributed to the work of **Rudolf Virchow**, who described the three key factors that contribute to thrombosis: 

1. **Endothelial injury** - Damage to the blood vessel lining.
2. **Abnormal blood flow** - Stasis or turbulent blood flow that can contribute to clot formation.
3. **Hypercoagulability** - An increased tendency for the blood to clot.

These principles are commonly referred to as "Virchow's triad." 

Choose the «positive value» of inflammation:

Question 85Answer

1.
the focus of inflammation can become a source of generalization of the infection in the body (for example, the development of sepsis)


2.
restoration of damaged tissue


3.
death of own cells and tissues


4.
edema can cause tissue malnutrition, hypoxia, intoxication


5.
cleansing the inflammation focus

The positive values of inflammation refer to the beneficial aspects of the inflammatory response that are vital for healing and recovery. Based on the options you provided, the correct choice representing a positive value of inflammation is:

**2. Restoration of damaged tissue**

This aspect highlights the role of inflammation in promoting healing and repair after tissue injury.

Additionally, another positive aspect can be considered:

**5. Cleansing the inflammation focus** - This refers to the process by which the body removes pathogens, dead cells, and debris from the site of inflammation, facilitating further healing.

The other options either describe negative consequences of inflammation or are related to outcomes that are not beneficial:

1. The focus of inflammation can indeed become a source of generalization of the infection, which is a negative outcome.
3. Death of own cells and tissues describes a detrimental effect of inflammation (necrosis).
4. Edema causing tissue malnutrition, hypoxia, and intoxication is a negative consequence associated with inflammation.

Therefore, the two selections among those provided that indicate “positive values” of inflammation are:

- **2. Restoration of damaged tissue**
- **5. Cleansing the inflammation focus** 

For your choice, you could select **2** as the clear positive value, while noting that **5** also has positive implications.

Choose the main manifestations of cell damage.

Question 86Answer

1.
Regeneration


2.
Dystrophy


3.
Impairments of subcellular structures


4.
Dysplasia


5.
Compensation

The main manifestations of cell damage can be identified among the options provided. Here’s an analysis of each option:

1. **Regeneration** - This refers to the process by which cells or tissues repair or replace themselves after injury. While regeneration can be a response to cell damage, it is not a manifestation of the damage itself but rather a potential outcome.

2. **Dystrophy** - This refers to abnormal or impaired development or growth of tissues and organs, often resulting from cell damage. Dystrophy is a manifestation of underlying pathologic processes.

3. **Impairments of subcellular structures** - This directly refers to the damage occurring at the cellular level, affecting organelles or other cellular components. It is a clear manifestation of cell damage.

4. **Dysplasia** - Dysplasia refers to the abnormal growth or development of cells, often in a tissue. It may represent an adaptive response to chronic injury or irritation, but it is not exclusively a manifestation of simple cell damage.

5. **Compensation** - This refers to the body’s mechanisms to adjust and adapt to stress or injury, which are responses rather than manifestations of direct cell damage.

### Conclusion
The main manifestations of cell damage from the options provided are:

- **2. Dystrophy**
- **3. Impairments of subcellular structures**
- **4. Dysplasia**

If you are looking for the most direct manifestations of cell damage, you would select **2 and 3**.

Indicate the type of ABS disorder if pH = 7.36

Question 87Answer

1.
decompensated


2.
acidosis


3.
subcompensated


4.
compensated


5.
alkalosis

A blood pH of 7.36 indicates a state of acidosis, as the normal pH range for arterial blood is approximately 7.35 to 7.45. 

Considering this pH value, we can assess the options:

1. **Decompensated** - This term typically refers to a physiological state where the body cannot adequately compensate for the acid-base disturbance, but we cannot determine this solely from pH value.
  
2. **Acidosis** - Since 7.36 is below the normal range, it is correct to categorize this state as acidosis.

3. **Subcompensated** - This may refer to a situation where there are some compensatory mechanisms in play but inadequate to bring the pH back to normal. Again, determining this requires additional information about other values such as bicarbonate (HCO3) or PCO2.

4. **Compensated** - If the system was compensated, you'd often expect a pH to be within the normal range, which it is not here.

5. **Alkalosis** - This is not applicable as the pH is not elevated.

Based on this evaluation, the best fit for a pH of 7.36 is:

**2. acidosis**

While further classification could include whether it is compensated or decompensated based on additional parameters, from the options given, **2. acidosis** is the most accurate identification.

Biogenic amines

Answer 3 Question 88Choose.


Kallidin


Histamine


○


Lymphokines

Here’s how to match the mediators of inflammation with their respective groups based on their chemical structures:

1. **Polypeptides**
   - **Lymphokines**  
     Lymphokines are signaling molecules produced by lymphocytes (a type of white blood cell) and are typically classified as polypeptides.

2. **Proteins**
   - **Kallidin**  
     Kallidin is a peptide, but it is often associated with the kinin system, which includes proteins involved in vascular and inflammatory responses.

3. **Biogenic amines**
   - **Histamine**  
     Histamine is a classic example of a biogenic amine involved in inflammatory responses, particularly in allergic reactions and local immune responses.

So the final matches would be:
- **Polypeptides:** **Lymphokines**
- **Proteins:** **Kallidin**
- **Biogenic amines:** **Histamine**

This should correctly categorize the mediators of inflammation based on their chemical structures.

proteins

Here's how to match the types of blood clots by structure with their predominant components:

1. **Red**  
   - **Red blood cells held together by fibrin strands**  
   This type of blood clot is primarily composed of red blood cells (erythrocytes) that are entangled within a network of fibrin.

2. **White**  
   - **Platelets, leukocytes, and small amounts of blood plasma proteins**  
   White clots are typically composed mainly of platelets and white blood cells (leukocytes), with lesser amounts of fibrin.

3. **Mixed**  
   - **Interleaved white and red blood cells**  
   Mixed clots contain both red and white blood cells and represent a combination of elements found in red and white clots.

So, the final matches would be:
- **Red:** **Red blood cells held together by fibrin strands**
- **White:** **Platelets, leukocytes, and small amounts of blood plasma proteins**
- **Mixed:** **Interleaved white and red blood cells**

This categorization describes blood clots based on their structural composition.
