HESI Med Surg Hematological

Correct Answer: B. Client A has a higher WBC count than normal, client B has a normal hemoglobin count, and client C has a normal platelet count.

Explanation:

B. Client A has a higher WBC count than normal, client B has a normal hemoglobin count, and client C has a normal platelet count.

Client A (WBC count of 24,500/mm3): A normal WBC count is generally between 4,500 and 11,000/mm3. A WBC count of 24,500/mm3 is significantly elevated, indicating a possible infection, inflammation, or hematological disorder. This is above normal.

Client B (Hemoglobin of 13.4 g/dL): Normal hemoglobin levels for a female range from 12.0-16.0 g/dL, and for a male from 13.5-17.5 g/dL. A hemoglobin level of 13.4 g/dL is within the normal range, indicating no abnormality.

Client C (Platelet count of 250,000/mm3): Normal platelet counts are typically between 150,000 and 450,000/mm3. A platelet count of 250,000/mm3 is within this normal range, indicating no platelet abnormality.

Why the Other Options Are Incorrect:

A. Client A has a normal WBC count, client B has a higher hemoglobin count than normal, and client C has a normal platelet count.

This is incorrect because Client A has a higher WBC count than normal (not a normal one). Additionally, Client B has a normal hemoglobin count, not a higher-than-normal one.

C. Client A has a higher WBC count than normal, client B has a normal hemoglobin count, and client C has a higher platelet count than normal.

This is incorrect because Client C has a platelet count that is within the normal range of 150,000-450,000/mm3, not a higher-than-normal count.

D. Client A has a normal WBC count than normal, client B has a normal hemoglobin count, and client C has a normal platelet count.

This is incorrect because Client A has an elevated WBC count, not a normal one.

Summary:

The correct answer is B. Client A has a higher WBC count than normal, client B has a normal hemoglobin count, and client C has a normal platelet count. This is the most accurate interpretation of the blood count values provided. The other options either misinterpret the WBC count, hemoglobin level, or platelet count.

Correct Answer: Bone marrow, Blood, Plasma, Plasma granulocytes

Explanation:

Bone marrow

Bone marrow is the primary site where hematopoiesis occurs, meaning it is where blood cells are produced. The student nurse must study bone marrow as a critical component of the hematopoietic system.

Blood

Blood itself is central to the hematopoietic system, as it carries the blood cells produced in the bone marrow throughout the body. Understanding the composition of blood (such as red blood cells, white blood cells, and platelets) is essential in learning about hematopoiesis.

Plasma

Plasma is the liquid component of blood and serves as the medium through which blood cells and nutrients are transported. It is a key area of study for understanding how blood and its components function.

Plasma granulocytes

Granulocytes are a type of white blood cell (leukocyte), and they are part of the hematopoietic system. They play a role in the immune response. Plasma granulocytes specifically refer to the presence of these cells in the plasma, which is an important topic in hematopoiesis.

Why the Other Option Is Incorrect:

E. Protein inhibitors

Protein inhibitors are not specifically related to the hematopoietic system in the same way that the other options are. While certain protein inhibitors can affect blood cell function or immune response, they are not a primary focus in the study of hematopoiesis.

Summary:

The correct answers are A. Bone marrow, B. Blood, C. Plasma, and D. Plasma granulocytes, as these are the primary components of the hematopoietic system. E. Protein inhibitors is not directly relevant to the basic study of hematopoiesis.

Correct Answer:

"mantle field radiation puts women at higher risk for breast cancer down the line":

Mantle field radiation is a type of radiation therapy typically used to treat Hodgkin's lymphoma. It targets the chest, neck, and underarm areas, which are areas where the lymphatic system is concentrated. Women who undergo mantle field radiation, especially at a young age, are at an increased risk for developing breast cancer later in life due to the exposure of the chest area to radiation.

Why Other Options Are wrong:

"mantle field radiation eliminates the option to use chemotherapy as a treatment option":

Mantle field radiation does not eliminate the use of chemotherapy. Chemotherapy and radiation therapy are often used in combination, depending on the stage and type of cancer.

"mantle field radiation can change the skin color of the upper chest permanently":

While it is true that radiation can cause skin changes, including pigmentation changes or irritation, this statement is too specific and might not apply to all patients. Radiation therapy does cause temporary or sometimes permanent skin changes, but not every patient will experience permanent color changes.

"there are no risk factors for mantle field radiation, it is always best choice":

Mantle field radiation has known risks, including the potential for secondary cancers (like breast cancer), heart disease, and lung complications. It is not always the best choice, and the risks must be weighed against the potential benefits in treatment planning.

Summary:

The nurse should explain that mantle field radiation puts women at a higher risk for breast cancer later in life due to the radiation exposure to the chest area.

Correct answer: D. Fever and sore throat

Explanation:

Leucopenia refers to a decrease in white blood cells, particularly neutrophils, which play a key role in the body's defense against infection. When a client is leucopenic, their ability to fight infections is impaired, making them more susceptible to bacterial and viral infections. Therefore, fever and sore throat are classic signs of infection and are important indicators that the client might be developing an infection due to their suppressed immune system. Prompt recognition of these signs is critical to prevent severe infections.

Why the Other Options Are Incorrect:

A. Unusual or easy bleeding.

This is more indicative of thrombocytopenia (low platelet count), not leucopenia. Thrombocytopenia increases the risk of bleeding, while leucopenia increases infection risk.

B. Oozing from injection sites.

Similar to option A, this relates more to impaired clotting due to low platelets or coagulation issues rather than leucopenia.

C. Dark, tarry stools.

This typically indicates gastrointestinal bleeding (melena), which is associated with bleeding disorders or gastrointestinal lesions, not with leucopenia.

Summary:

The correct answer is D. Fever and sore throat, because these are hallmark signs of infection that can result from leucopenia due to the client's reduced white blood cell count. The other options are associated with bleeding tendencies, which are not directly related to leucopenia.

Correct Answer: A combination of a weak saline and water solution should be used to rinse the mouth before and after each meal

Explanation:

Oral mucositis is a painful inflammation and ulceration of the mucous membranes lining the mouth, commonly caused by radiation therapy to the head and neck or chemotherapy. To promote healing and reduce discomfort, it is essential to maintain gentle, frequent oral hygiene. A weak saline solution (salt water) helps to keep the mouth clean, reduce bacteria, and soothe irritated tissues without being too harsh.

Rinsing before and after meals helps remove food particles, reduces the risk of infection, and can make eating more comfortable. This practice is widely recommended as a core part of mucositis care.

Why the Other Options Are Incorrect:

Oral hygiene should be performed in the morning and evening

While oral hygiene is critical, in cases of mucositis, more frequent and gentle oral care (such as after every meal and at bedtime) is preferred. Limiting it to just morning and evening is inadequate for optimal care.

High-protein foods, such as peanut butter, should be incorporated in the diet

Protein is important for healing, but peanut butter is thick and sticky, which can be difficult and painful to swallow for someone with mucositis. Softer, non-irritating, high-protein options like scrambled eggs or smoothies are better tolerated.

A glass of wine per day will not pose any further harm to the oral cavity

Alcohol is an irritant and can worsen mucosal damage. It also dries out the mucosa and increases discomfort and the risk of infection. It should be avoided entirely during mucositis.

Summary:

The most appropriate and evidence-based home care measure for oral mucositis is a combination of a weak saline and water solution should be used to rinse the mouth before and after each meal, as it helps maintain oral hygiene and promotes healing without irritating the sensitive tissue.

Correct Answer: Neurologic involvement

Explanation:

Pernicious anemia is a type of vitamin B12 deficiency anemia, and one of its common manifestations is neurological involvement. Numbness and tingling in the arms and legs, also known as "paresthesia," are classic signs of nerve damage that can occur in pernicious anemia due to a lack of vitamin B12, which is essential for proper nerve function. This condition can lead to nerve degeneration and neurological symptoms, including the sensation of tingling and numbness, and, if untreated, can lead to more severe nerve damage.

Why the Other Options Are Incorrect:

Loss of vibratory and position senses

While loss of vibratory and position senses can occur with pernicious anemia due to neurological involvement, the primary concern here is the presence of numbness and tingling, which is more directly associated with neurologic involvement. Loss of vibratory and position senses are specific manifestations of neuropathy that can develop later in the disease, but they are not the primary description of the symptoms presented.

Severity of the disease

The symptoms of numbness and tingling do not necessarily correlate with the severity of the disease. They are more indicative of the onset of neurological complications due to prolonged B12 deficiency. Therefore, these symptoms are not a reliable indicator of the overall severity of the disease, but rather the type of complications the client may be experiencing.

Insufficient intake of dietary nutrients

While pernicious anemia is caused by a deficiency in vitamin B12, this is often due to malabsorption (related to intrinsic factor production), not insufficient intake alone. Therefore, the tingling and numbness are more indicative of neurologic involvement from B12 deficiency rather than just dietary insufficiency.

Summary:

The correct answer is B. Neurologic involvement. Numbness and tingling in the arms and legs in a client with pernicious anemia most likely indicate the neurological complications associated with vitamin B12 deficiency. Early detection and treatment of B12 deficiency are important to prevent irreversible nerve damage.

Correct Answer: Transportation of O2 to the tissues and removal of CO2 from the tissues

Explanation:

The primary function of erythrocytes (red blood cells) is to transport oxygen (O2) from the lungs to the tissues and organs throughout the body and to carry carbon dioxide (CO2) from the tissues back to the lungs for exhalation. This is achieved through the binding of O2 and CO2 to hemoglobin molecules within the erythrocytes.

Why the Other Options Are Incorrect:

Act as mediators for the immune system

This function is primarily carried out by white blood cells (leukocytes), not erythrocytes. Leukocytes are responsible for immune response and mediating defense mechanisms against pathogens.

Destroy invading organisms

This function is also carried out by white blood cells, particularly neutrophils, macrophages, and lymphocytes, which are involved in phagocytosis and immune defense against invading organisms. Erythrocytes do not play a direct role in destroying pathogens.

Oxygenation of the brain

While erythrocytes are responsible for transporting oxygen to all tissues and organs, including the brain, the term "oxygenation of the brain" is too specific and does not reflect the general role of erythrocytes, which is to deliver oxygen to all cells in the body, not just the brain.

Summary:

Erythrocytes are primarily responsible for transporting oxygen and carbon dioxide throughout the body. The other options describe functions of white blood cells or are not accurate descriptions of erythrocyte functions.

Correct Answer: Safety

Explanation:

Multiple myeloma is a cancer of the plasma cells in the bone marrow, which can lead to bone damage, including bone pain, osteoporosis, and fractures. Clients with multiple myeloma are at an increased risk of pathological fractures (fractures that occur without significant trauma) due to the destruction of bone by the cancer cells. This makes safety the most important nursing priority in preventing fractures during activities like ambulation.

When assisting a client with multiple myeloma to ambulate, it is essential to ensure the environment is safe to prevent falls and injuries. This includes providing supportive devices (such as walkers or canes), making sure the pathway is clear of obstacles, and offering assistance with balance and coordination. By focusing on safety, the nurse can help prevent falls and fractures that are more likely due to weakened bones from the disease.

Why the Other Options Are Incorrect:

A. Increased mobility

While maintaining mobility is important for overall health, especially in clients with multiple myeloma, increased mobility does not specifically address the risk of fractures. The focus should be on safe ambulation rather than just increasing the amount of movement. The client's bones are already compromised due to bone marrow involvement, and the primary concern is preventing fractures during ambulation, not solely increasing mobility.

B. Adequate hydration

Adequate hydration is important for clients with multiple myeloma, particularly to help with kidney function and to reduce the risk of hypercalcemia (which can occur due to bone breakdown). However, hydration does not directly address the risk of fractures from weakened bones. Safety is a more critical focus to prevent injury while ambulating.

D. Adequate nutrition

While adequate nutrition is essential for overall health, particularly for supporting bone health (e.g., calcium and vitamin D for bone strength), the primary concern in preventing fractures during ambulation is ensuring the client's safety during movement. While nutrition plays a role in long-term bone health, safety is more immediate and vital to prevent falls and fractures in the client with multiple myeloma.

Summary:

The most important nursing diagnosis to help prevent fractures in a client with multiple myeloma during ambulation is safety, as the client is at high risk for fractures due to weakened bones. 

Correct Answer: Helps retain fluid in the vascular compartment.

Explanation:

Albumin plays a crucial role in maintaining the osmotic pressure in the blood vessels. Because albumin molecules are large and do not easily pass through the capillary walls, they create an osmotic pull that helps retain fluid within the vascular compartment. This process is important for maintaining blood volume and preventing excessive fluid from leaking into the tissues, which could lead to edema.

Why the Other Options Are Incorrect:

Helps push oxygen into the tissues of the body.

While albumin is important in maintaining fluid balance, it does not have a direct role in the transport of oxygen. Oxygen is carried by red blood cells through hemoglobin, not by albumin.

Retains leukocytes in the vascular compartment.

Albumin does not have a significant role in retaining leukocytes (white blood cells) in the vascular compartment. Leukocytes move freely through the bloodstream and can exit the capillaries during immune responses, but this process is controlled by other factors, not albumin.

Absorbs carbon dioxide from the tissues for transport to the lungs.

Carbon dioxide is carried in the blood primarily by bicarbonate ions and hemoglobin, not albumin. While albumin can bind to small amounts of carbon dioxide, it is not the main protein responsible for its transport.

Summary:

Helps retain fluid in the vascular compartment because albumin creates the osmotic pressure that keeps fluid in the blood vessels. The other options describe functions unrelated to albumin's primary role.
