Question

A child has Down syndrome and has been experiencing unexplained nose bleeds for the past several months. His blood tests identify blast cells in the peripheral smear. In addition to nose bleeds, his acute leukemia will typically manifest which of the following signs/symptoms? Select all that apply.

Answer 1

Correct Answers:

Bleeding due to thrombocytopenia
Infections due to neutropenia
Fatigue due to RBC deficiency
Hypogammaglobulinemia due to progressive infiltration of the bone marrow and lymphoid tissues

Rationale :

Bleeding due to thrombocytopenia

💠 Acute leukemia causes bone marrow failure, leading to decreased platelet production (thrombocytopenia).

💠 Low platelet levels impair normal clotting, resulting in easy bruising, petechiae, and recurrent nosebleeds (epistaxis).

💠 Children with leukemia commonly present with mucosal bleeding due to inadequate platelet function.

💠 The presence of blast cells crowds out normal megakaryocytes, reducing platelet formation.

💠 Bleeding tendencies are often one of the earliest clinical manifestations of leukemia.

Infections due to neutropenia

💠 Leukemic blast proliferation suppresses normal white blood cell production, especially neutrophils.

💠 Neutropenia significantly increases the risk for recurrent or severe infections.

💠 Even though total WBC count may appear elevated, the circulating cells are often immature and nonfunctional.

💠 Children may experience frequent fevers, oral ulcers, or persistent infections.

💠 Infection is a major cause of morbidity in pediatric acute leukemia.

Fatigue due to RBC deficiency

💠 Bone marrow infiltration reduces production of red blood cells, causing anemia.

💠 Anemia leads to fatigue, pallor, weakness, and shortness of breath.

💠 Reduced hemoglobin decreases oxygen delivery to tissues, resulting in cellular hypoxia.

💠 Children may show decreased activity tolerance and irritability.

💠 Anemia is a common presenting feature alongside bleeding and infection.

Hypogammaglobulinemia due to progressive infiltration of the bone marrow and lymphoid tissues

💠 Leukemic infiltration disrupts normal B-cell function, impairing antibody production.

💠 This can result in hypogammaglobulinemia, further increasing susceptibility to infections.

💠 Immune dysfunction is common due to replacement of normal lymphoid tissue by malignant cells.

💠 Decreased immunoglobulin levels weaken the body's ability to fight pathogens.

💠 Immunosuppression is both disease-related and treatment-related in leukemia.

Palpation of solid tumors on the kidneys

💠 Solid renal tumors are more characteristic of Wilms tumor, not acute leukemia.

💠 Leukemia primarily affects the bone marrow and blood, not as localized kidney masses.

Answer 2

Correct Answers:

Cancer cells have shorter cell cycle times than normal cells.
Cancer cells do not die when they are programmed to die.

Rationale :

💠 Cancer cells often have dysregulated cell cycle control, allowing them to progress rapidly through checkpoints.

💠 Mutations in regulatory genes such as oncogenes and tumor suppressor genes (e.g., p53) shorten the time between cell divisions.

💠 Faster cycling leads to accelerated proliferation, contributing to rapid tumor growth.

💠 Normal cells carefully regulate progression through the G1, S, G2, and M phases, whereas cancer cells bypass these controls.

💠 Shortened cell cycle time increases the total number of malignant cells in a short period.

Cancer cells do not die when they are programmed to die

💠 Normal cells undergo apoptosis (programmed cell death) when damaged or no longer needed.

💠 Cancer cells evade apoptosis due to mutations that disable cell death pathways.

💠 This resistance allows abnormal cells to survive longer than normal cells.

💠 Accumulation of cells occurs because they continue dividing without undergoing normal turnover.

💠 Failure of apoptosis is a key hallmark of malignancy and contributes significantly to tumor expansion.

Cancer cells will reach a balance between cell birth and cell death rate.

💠 Tumor growth occurs because there is loss of balance, with cell proliferation exceeding cell death.

💠 A balance would prevent progressive tumor enlargement.

Cancer cells never reach a flattened growth rate.

💠 Some tumors may slow in growth due to nutrient limitation or treatment effects.

💠 This statement is overly absolute and not physiologically accurate.

Cancer cells tend to grow rapidly

💠 While many cancers grow rapidly, this statement describes an observation rather than aphysiological mechanism.

💠 The underlying principles involve shortened cell cycles and resistance to apoptosis.

Answer 3

Correct Answers:

A middle-aged female experiencing menopause due to loss of estrogen stimulation

Rationale :

💠 Cellular atrophy is a decrease in cell size due to reduced functional demand or loss of trophic stimulation.

💠 During menopause, declining estrogen levels lead to reduced stimulation of estrogen-dependent tissues such as the uterus and vaginal epithelium.

💠 This hormonal withdrawal causes shrinkage of reproductive organs, which is a classic example of physiologic atrophy.

💠 Atrophy involves decreased protein synthesis and increased protein breakdown within the affected cells.

💠 The process is adaptive and not necessarily pathologic, as it reflects normal aging changes.

A female client with the change in uterine size as a result of pregnancy

💠 Uterine enlargement during pregnancy is due to hyperplasia and hypertrophy, not atrophy.

💠 Cells increase in size and number to support fetal development.

A hypertensive, noncompliant client who has developed a progressive increase in left ventricular mass

💠 Increased left ventricular mass is an example of hypertrophy, caused by increased workload.

💠 Cardiac muscle cells enlarge to compensate for elevated blood pressure.

A post nephrectomy client whose remaining kidney enlarges to compensate for the loss

💠 Enlargement of the remaining kidney is compensatory hypertrophy.

💠 The existing cells increase in size to maintain adequate renal function.

Answer 4

Correct Answers:

A middle-aged female experiencing menopause due to loss of estrogen stimulation

Rationale :

💠 Cellular atrophy refers to a decrease in cell size resulting from reduced stimulation or workload.

💠 During menopause, there is a significant decline in estrogen production, which removes trophic hormonal support from reproductive tissues.

💠 The uterus and vaginal tissues undergo physiologic shrinkage due to decreased protein synthesis and cellular activity.

💠 This process represents a normal adaptive response to aging rather than a disease state.

💠 Atrophy occurs because cells reduce their structural components when stimulation is no longer present.

A female client with the change in uterine size as a result of pregnancy

💠 Uterine enlargement during pregnancy is due to hypertrophy and hyperplasia, not atrophy.

💠 Cells increase in both size and number to accommodate fetal growth.

A hypertensive, noncompliant client who has developed a progressive increase in left ventricular mass

💠 Increased ventricular mass is an example of hypertrophy caused by chronic increased workload.

💠 Cardiac muscle fibers enlarge to compensate for elevated blood pressure.

A post nephrectomy client whose remaining kidney enlarges to compensate for the loss

💠 Enlargement of the remaining kidney is compensatory hypertrophy.

💠 The existing renal cells increase in size to maintain function.

Answer 5

Correct Answers:

IgM

Rationale :

💠 IgM antibodies are primarily responsible for ABO blood group incompatibility reactions during transfusions.

💠 Individuals naturally develop anti-A or anti-B antibodies (IgM) early in life without prior transfusion exposure.

💠 IgM is highly effective at activating the complement system, leading to rapid intravascular hemolysis of incompatible red blood cells.

💠 Because IgM is a large pentamer molecule, it remains mainly in the intravascular space, intensifying acute transfusion reactions.

💠 ABO mismatched transfusions can result in hemolysis, fever, hypotension, and acute kidney injury, all mediated by IgM-driven complement activation.

IgD

💠 IgD functions mainly as a receptor on immature B cells.

💠 It does not play a role in transfusion incompatibility reactions.

IgE

💠 IgE is primarily involved in allergic and hypersensitivity reactions.

💠 It mediates responses related to mast cells and histamine release, not ABO reactions.

IgA

💠 IgA is found mainly in mucosal secretions such as saliva and breast milk.

💠 It protects mucosal surfaces rather than mediating blood transfusion reactions.

IgG

💠 IgG is responsible for Rh incompatibility reactions, not ABO incompatibility.

💠 IgG can cross the placenta and is involved in hemolytic disease of the newborn.

Answer 6

Correct Answers:

Histamine

Rationale :

💠 Histamine is released from mast cells and basophils during immune and inflammatory reactions, especially in type I hypersensitivity responses.

💠 It directly causes vasodilation of local blood vessels, which increases blood flow to the affected area and produces redness.

💠 Histamine increases capillary permeability, allowing plasma proteins and fluid to leak into surrounding tissues.

💠 The movement of fluid into interstitial spaces results in edema and swelling, which are hallmark signs of inflammation.

💠 Histamine also stimulates sensory nerve endings, contributing to itching and discomfort during allergic reactions.

Tumor necrosis factor

💠 Tumor necrosis factor (TNF) promotes systemic inflammation and fever.

💠 It contributes to immune cell activation but is not the primary mediator of immediate vasodilation and edema.

Cytokines

💠 Cytokines are signaling proteins that regulate immune responses.

💠 They coordinate inflammation but do not directly cause rapid vascular permeability changes like histamine.

Prostaglandins

💠 Prostaglandins contribute to pain and fever during inflammation.

💠 Although they influence vascular tone, histamine is the primary mediator of acute permeability and edema.

Answer 7

Correct Answers:

Autograft

Rationale :

💠 An autograft is a tissue graft taken from one site of a patient’s body and transplanted to another site on the same person.

💠 In burn management, skin harvested from an uninjured area such as the thigh is commonly used to cover the burn wound.

💠 Because the tissue comes from the same individual, there is no risk of immune rejection.

💠 Autografts provide permanent wound coverage and promote optimal healing and reduced infection risk.

💠 This type of graft is considered the gold standard in burn treatment when sufficient healthy donor skin is available.

Xenograft

💠 A xenograft is tissue transplanted from a different species, such as pig skin.

💠 It is typically used as temporary coverage and carries a risk of immune reaction.

Isograft

💠 An isograft is tissue transplanted between genetically identical individuals, such as identical twins.

💠 It is not taken from the same individual.

Allograft

💠 An allograft is tissue transplanted between two genetically different individuals of the same species.

💠 It carries a risk of immune rejection and is often used temporarily in burn care.

Answer 8

Correct Answers:

Artificial active

Rationale :

💠 Artificial active immunity occurs when a person is intentionally exposed to an antigen through vaccination to stimulate an immune response.

💠 Vaccines contain weakened, inactivated, or antigenic components of a pathogen that trigger the body to produce specific antibodies and memory cells.

💠 This immune response allows the body to mount a faster and stronger defense upon future exposure to the actual pathogen.

💠 The immunity develops over time and typically provides long-term protection due to immunologic memory.

💠 Because the antigen exposure is deliberate and the body produces its own antibodies, it is classified as artificial (man-made) and active (self-produced antibodies).

Artificial passive

💠 Artificial passive immunity involves administration of preformed antibodies, such as immunoglobulin injections.

💠 It provides immediate but temporary protection without stimulating memory cell formation.

Natural passive

💠 Natural passive immunity occurs when antibodies are transferred from mother to fetus through the placenta or breast milk.

💠 The recipient does not produce their own antibodies in this process.

Natural active

💠 Natural active immunity develops after exposure to an infectious pathogen.

💠 The immune system produces antibodies following natural infection, not vaccination.

Answer 9

Correct Answers

Blank 1 Correct Option: Wet
Blank 2 Correct Option: Dry

Rationale :

💠 Wet gangrene occurs when tissue necrosis is accompanied by a bacterial infection, leading to rapid tissue destruction.

💠 The affected area appears moist, swollen, black or darkened, and often emits a foul odor due to bacterial decomposition.

💠 It is commonly associated with compromised blood flow combined with infection, such as in diabetic foot ulcers.

💠 Wet gangrene spreads quickly because bacteria thrive in the moist, ischemic environment.

💠 This condition is considered a medical emergency due to the high risk of sepsis.

Dry gangrene results from chronic ischemia without infection

💠 Dry gangrene develops from prolonged arterial insufficiency, leading to gradual tissue death.

💠 The affected tissue appears dark, dry, shrunken, and leathery, often described as mummified.

💠 There is typically a clear line of demarcation between viable and necrotic tissue.

💠 It progresses more slowly than wet gangrene because infection is not initially present.

💠 Dry gangrene may convert to wet gangrene if secondary infection develops.

Answer 10

Correct Answers:

Yellowish discoloration of the skin and sclera of the eye

Rationale :

💠 A bilirubin level of 13 mg/dL in a newborn indicates hyperbilirubinemia, which commonly manifests as jaundice.

💠 Jaundice presents as yellow discoloration of the skin and sclera, beginning on the face and progressing downward (cephalocaudal pattern).

💠 Newborns are prone to elevated bilirubin due to immature liver function, which reduces their ability to conjugate and excrete bilirubin efficiently.

💠 Increased breakdown of fetal red blood cells after birth also contributes to higher bilirubin production.

💠 Monitoring is essential because excessively high bilirubin levels can lead to kernicterus and neurological damage if untreated.

Dark-colored urine with foul odor

💠 Dark, foul-smelling urine is more suggestive of urinary tract infection, not hyperbilirubinemia.

💠 Newborn jaundice primarily affects skin and sclera rather than urine odor.

Xanthomas with swelling

💠 Xanthomas are cholesterol deposits seen in lipid disorders.

💠 They are not associated with neonatal hyperbilirubinemia.

Colicky, intermittent pain associated with formula feeding

💠 Colicky pain relates to gastrointestinal discomfort, not bilirubin elevation.

💠 Hyperbilirubinemia does not present with feeding-related abdominal pain.
