Question

Which statement best describes the pathophysiology of Disseminated Intravascular Coagulation (DIC)?

Answer 1

Correct Answers:

Small clots form and clotting factors are depleted causing both tissue ischemia and bleeding

Rationale :

🔷 Disseminated intravascular coagulation (DIC) is characterized by widespread activation of clotting, which causes small clots to form throughout the bloodstream.

🔷 These microclots can obstruct blood flow and lead to tissue ischemia and organ damage.

🔷 As clotting continues abnormally, the body uses up platelets and clotting factors, creating a high risk for serious bleeding.

🔷 This is why DIC causes the dangerous combination of thrombosis and hemorrhage at the same time.

🔷 This statement best describes the underlying pathophysiology of DIC.

Red blood cells are destroyed, leading to hemolytic anemia.

🔷 This describes hemolysis, not the clotting-factor consumption pattern seen in DIC.

🔷 DIC is primarily a disorder of abnormal coagulation and bleeding, not isolated red blood cell destruction.

Too many red blood cells are being produced causing an increased number of erythrocytes (RBCs).

🔷 This describes polycythemia, not DIC.

🔷 DIC involves abnormal clot formation and depletion of clotting components rather than excess RBC production.

An inherited disorder causing decreased platelets and excessive bleeding.

🔷 DIC is generally an acquired condition triggered by severe illness, not an inherited platelet disorder.

🔷 Although bleeding occurs, the mechanism is widespread clotting with factor depletion, not simply inherited thrombocytopenia.

Answer 2

Correct Answers:

AB positive

Rationale :

💎 AB positive is the universal recipient for red blood cell transfusions.

💎 People with AB blood do not have anti-A or anti-B antibodies that would attack donor RBCs from the ABO groups.

💎 Being Rh-positive also means they can receive both Rh-positive and Rh-negative blood.

💎 This combination makes AB positive the broadest compatible recipient type.

💎 For ABO/Rh red cell transfusion questions, AB positive is the safest universal recipient answer.

O negative

💎 O negative is the classic universal donor for red blood cells, not the universal recipient.

💎 People with O blood have antibodies against A and B antigens, so they cannot safely receive blood from any ABO type.

O positive

💎 O positive can receive O-positive and O-negative red cells, but not blood from every ABO type.

💎 It is not considered the universal recipient.

AB negative

💎 AB negative can receive ABO-compatible blood, but Rh-negative status limits compatibility with Rh-positive blood.

💎 Because of that Rh restriction, it is not the universal recipient.

Answer 3

Correct Answers:

Initiate assessment of nutritional status and electrolyte levels to guide treatment.

Rationale :

🟣 The client’s weight loss, fatigue, and pale, bulky floating stools suggest malabsorption with steatorrhea.

🟣 Malabsorption can lead to significant vitamin, mineral, protein, and electrolyte deficiencies, so assessing nutritional status is a priority.

🟣 Chronic diarrhea also increases the risk of fluid and electrolyte imbalance, which can worsen weakness and systemic instability.

🟣 Before choosing a diet plan or symptom-focused treatment, the nurse needs data to identify the severity of deficiencies and guide safe therapy.

🟣 This makes a focused nutritional and electrolyte assessment the priority intervention.

Encourage increased fiber intake to bulk up stool and reduce diarrhea.

🟣 Increasing fiber does not address the underlying problem of fat malabsorption and may worsen symptoms in some clients.

🟣 The priority is first identifying nutritional deficits and biochemical imbalances.

Administer antidiarrheal medications to reduce stool frequency immediately.

🟣 Symptom control alone does not correct the likely malabsorption syndrome or its nutritional consequences.

🟣 The nurse should first assess for dehydration, deficiencies, and the cause of the diarrhea.

Recommend a low-fat, high-carbohydrate diet to improve stool consistency.

🟣 Diet changes may eventually be part of care, but they should not come before a complete assessment of nutritional status and electrolytes.

🟣 Priority nursing action is guided assessment, especially in a client already showing weight loss and fatigue.

Answer 4

Correct Answers:

The client is most likely experiencing a bacterial infection.

Rationale :

🔶 A WBC count of 15,800/mm³ indicates leukocytosis, and the elevated neutrophils are especially important.

🔶 Neutrophils are the white blood cells most strongly associated with fighting bacterial infections.

🔶 When neutrophils are increased, the body is often responding to an acute bacterial process.

🔶 This pattern is called neutrophilia, and it commonly points toward bacterial infection rather than allergy or neutropenia.

🔶 The laboratory results are most consistent with a bacterial infection.

The client should be placed on neutropenic precautions.

🔶 Neutropenic precautions are used when the neutrophil count is low, not high.

🔶 This client has elevated neutrophils, which indicates the opposite problem.

The client is most likely experiencing a viral infection.

🔶 Viral infections are more commonly associated with lymphocyte changes rather than neutrophilia.

🔶 Elevated neutrophils make a bacterial infection more likely.

The client is most likely experiencing an allergic response.

🔶 Allergic responses are more commonly linked with eosinophils, not neutrophils.

🔶 This differential pattern supports bacterial infection instead.

Answer 5

Correct Answers:

Urine output 25 mL/hr

Rationale :

🔴 Urine output of 25 mL/hr is the strongest sign of worsening organ hypoperfusion from ongoing GI bleeding.

🔴 Reduced urine output reflects decreased blood flow to the kidneys and is an early marker of worsening shock.

🔴 GI bleeding can cause a rapid pulse, cool clammy skin, and eventually low urine output, but oliguria directly signals impaired end-organ perfusion.

🔴 Even though the blood pressure is still 110/70 mm Hg, compensatory mechanisms may temporarily maintain it while perfusion is already worsening.

🔴 Because kidney perfusion is being compromised, this finding requires the most immediate nursing attention.

Blood pressure 110/70 mm Hg

🔴 This blood pressure is not yet the clearest sign of deterioration in the setting described.

🔴 Clients can compensate for blood loss for a period before hypotension becomes obvious.

Skin cool and clammy

🔴 Cool, clammy skin does suggest sympathetic compensation and poor perfusion, but it is less specific than falling urine output for organ compromise.

🔴 Urine output gives a more direct sign that perfusion to the kidneys is worsening.

Heart rate 118 bpm

🔴 Tachycardia is an important compensation sign, but it often appears before more serious end-organ hypoperfusion.

🔴 Oliguria points more directly to worsening shock severity.

Answer 6

Correct Answers:

Foods high in B-12 like meat and seafood

Rationale :

🟢 Pernicious anemia is an autoimmune vitamin B12 deficiency caused by impaired absorption related to intrinsic factor problems.

🟢 Even though many clients need B12 replacement therapy, dietary teaching should still encourage B12-rich foods such as meat, fish, seafood, eggs, and dairy.

🟢 Vitamin B12 is naturally found in foods of animal origin, not mainly in fruits or leafy vegetables.

🟢 Adequate B12 is essential for red blood cell formation, neurologic function, and DNA synthesis.

🟢 For this reason, foods high in vitamin B12 are the best dietary recommendation.

Foods high in Vit. C like citrus fruits

🟢 Vitamin C helps with some aspects of iron absorption, but it does not correct vitamin B12 deficiency.

🟢 Pernicious anemia specifically requires attention to B12, not citrus intake.

Foods high in iron like organ meats and eggs

🟢 Iron-rich foods are helpful in iron-deficiency anemia, but pernicious anemia is not caused by iron deficiency.

🟢 The key deficiency in pernicious anemia is vitamin B12.

Foods high in folate like green leafy vegetables

🟢 Folate is important in some megaloblastic anemias, but pernicious anemia is specifically related to B12 deficiency.

🟢 Giving emphasis to folate alone would not address the main cause of this disorder.

Answer 7

Correct Answers:

Cut the wires immediately to open the mouth and clear the airway.

Rationale :

⚫ In a post-operative client with the jaw wired shut, vomiting plus respiratory distress creates an immediate airway emergency.

⚫ Emergency instructions for wired jaws specify that if the patient vomits or has trouble breathing, the wires may need to be cut right away.

⚫ Opening the mouth allows the airway to be cleared and reduces the risk of aspiration and complete obstruction.

⚫ Airway patency always takes priority over preserving the fixation in an acute respiratory emergency.

⚫ The nurse should act quickly to protect oxygenation and ventilation first.

Position the patient in high Fowler's position to facilitate drainage.

⚫ Positioning may help somewhat, but it does not solve the danger of a wired-shut mouth during active vomiting and respiratory distress.

⚫ The immediate priority is removing the barrier to airway clearance.

Encourage the patient to take deep breaths to clear the airway.

⚫ Deep breathing will not safely clear vomitus from a blocked or threatened airway in this situation.

⚫ The client needs emergency airway access, not coaching alone.

Suction the mouth vigorously to remove vomitus.

⚫ Suction may help with secretions, but with the jaw wired shut it may not adequately relieve the obstruction.

⚫ The more definitive priority action in vomiting with respiratory distress is to cut the wires in an emergency.

Answer 8

Correct Answers:

Hematocrit 57%

Rationale :

🟡 Secondary polycythemia in long-standing COPD develops as a compensatory response to chronic hypoxemia.

🟡 This causes the body to produce more red blood cells, which raises the hematocrit and hemoglobin.

🟡 A hematocrit of 57% is abnormally high and strongly supports polycythemia.

🟡 Research in COPD commonly identifies concerning polycythemia at hematocrit levels around or above 55%.

🟡 This laboratory value is the finding most consistent with secondary polycythemia.

Hematocrit 35%

🟡 A hematocrit of 35% is low, not elevated.

🟡 This finding suggests anemia rather than polycythemia.

Hemoglobin 11 g/dL

🟡 A hemoglobin of 11 g/dL is below the range expected in polycythemia.

🟡 Secondary polycythemia is associated with increased, not decreased, red cell measures.

Platelet count 150,000/mm3

🟡 This platelet count is at the low end of normal and does not diagnose polycythemia.

🟡 Polycythemia is identified primarily by elevated hematocrit or hemoglobin, not platelets.

Answer 9

Correct Answers:

Monitor for dehydration and electrolyte imbalance

Rationale :

🟤 In the diuretic phase of recovery from acute kidney injury (AKI), urine output rises, but the kidneys may still be unable to concentrate urine normally.

🟤 This creates a major risk for dehydration, volume depletion, and electrolyte imbalance.

🟤 Safe nursing care during this phase includes careful monitoring of fluid balance, sodium, potassium, and overall clinical status.

🟤 Aggressively restricting fluids or increasing potassium without assessment could be harmful.

🟤 The priority is close monitoring to prevent complications while renal function continues to recover.

Restrict fluids aggressively

🟤 Aggressive fluid restriction can worsen dehydration during the diuretic phase.

🟤 The problem at this stage is often excessive fluid loss, not overload.

Prepare for immediate dialysis

🟤 Dialysis may be needed in some AKI cases, but increased urine output in the recovery phase does not by itself make immediate dialysis the priority.

🟤 Ongoing assessment of fluid and electrolyte status comes first here.

Increase potassium intake

🟤 Potassium intake should not be increased automatically because electrolyte values must guide replacement.

🟤 The client may be at risk for imbalance, so monitoring is safer than assuming potassium is low.

Answer 10

Correct Answers:

Assess for restlessness, headaches, and changes in mental status

Rationale :

⭐ A platelet count of 8,000/mm³ indicates severe thrombocytopenia with a very high risk of spontaneous bleeding.

⭐ The most dangerous bleeding complication is intracranial hemorrhage, so neurological changes must be treated as the priority assessment.

⭐ Restlessness, headache, and altered mental status may be early signs of central nervous system bleeding.

⭐ While petechiae and bruising are common, they are usually less immediately life-threatening than bleeding in the brain.

⭐ Because intracranial bleeding can rapidly become fatal, the nurse should prioritize neurological assessment first.

Assess vital signs every hour

⭐ Vital signs are important, but they are not the most focused priority when the platelet count is critically low and intracranial bleeding is the main concern.

⭐ Neurological changes can reveal life-threatening hemorrhage earlier and more specifically.

Assess for a family history of genetic bleeding disorders

⭐ Family history may be useful later, but it does not address the immediate danger posed by a platelet count of 8,000/mm³.

⭐ The priority is identifying active or life-threatening bleeding right now.

Assess for petechiae and bruising on the skin.

⭐ Petechiae and bruising are expected signs of thrombocytopenia, but they are not as critical as evidence of intracranial bleeding.

⭐ Neurological assessment takes priority because CNS hemorrhage is the more urgent threat.
