Question

What type of anemia is caused by lack of intrinsic factor?

Answer 1

Correct Answers:

Pernicious anemia

Rationale :

🧬Pernicious anemia occurs due to a lack of intrinsic factor, a protein made by parietal cells in the stomach necessary for vitamin B12 absorption.

🧠Without intrinsic factor, even if vitamin B12 is present in the diet, the body cannot absorb it, leading to a functional deficiency.

🩺This deficiency disrupts DNA synthesis in red blood cell production, causing megaloblastic anemia, which results in large, immature, and ineffective red blood cells.

🔬Additionally, neurological symptoms such as numbness, tingling, and cognitive issues may develop, which are unique to B12-related anemia.

📌Core message

Pernicious anemia develops from a lack of intrinsic factor, leading to vitamin B12 deficiency and the production of megaloblastic red blood cells.

Answer 2

Correct Answers:

Encouraging fluid intake
Passive range of motion exercises
Regular repositioning of the patient
Use of compression stockings

Rationale :

🛏️Encouraging fluid intake helps prevent urinary stasis and kidney stones, common in immobile clients.

🦵Passive range of motion exercises prevent joint contractures and muscle atrophy, maintaining limb flexibility.

🔄Regular repositioning helps avoid pressure injuries and improves circulation to dependent areas.

🧦Compression stockings support venous return and reduce the risk of deep vein thrombosis (DVT) in clients with limited mobility.

📌Core message

Preventing complications of immobility involves maintaining circulation, promoting movement, and preventing pressure injuries and clots.

Answer 3

Correct Answers:

Autonomic dysreflexia

Rationale :

🧠Autonomic dysreflexia is a life-threatening condition seen in clients with spinal cord injuries above T6.

📈It is characterized by sudden hypertension, bradycardia, flushing above, and coolness below the injury.

💡Triggers include bladder distention, bowel impaction, or tight clothing, causing autonomic overreaction.

🛑Immediate intervention is needed to remove the trigger and prevent stroke or seizures.

📌Core message

Autonomic dysreflexia is a critical complication of high spinal cord injury, marked by hypertension and autonomic instability.

Answer 4

Correct Answers:

50-year-old with atherosclerotic heart disease
55-year-old that smokes two packs of cigarettes a day
75-year-old with hypertension

Rationale :

🩸Atherosclerotic heart disease leads to plaque buildup in arteries, which narrows vessel lumens and reduces blood flow, increasing the risk of poor perfusion to tissues and organs.

🚬Smoking contributes to endothelial damage, vasoconstriction, and the development of atherosclerosis, all of which impair oxygen and nutrient delivery to tissues.

👵Hypertension in older adults causes chronic vascular remodeling and stiffness, decreasing circulatory efficiency and worsening perfusion over time.

🧠These individuals are particularly vulnerable to complications like stroke, myocardial infarction, and renal ischemia due to compromised vascular integrity and circulation.

📌Core message

Atherosclerosis, smoking, and hypertension significantly increase the risk of impaired perfusion by compromising blood vessel function.

Answer 5

Correct Answers:

Blood clot

Rationale :

🩸A blood clot (thrombus) is a major cause of acute perfusion impairment, as it can block blood flow in critical arteries, such as in the heart, brain, or lungs.

🧠This obstruction prevents oxygen and nutrients from reaching tissues, leading to ischemia and potentially infarction if not resolved promptly.

💉Blood clots can result from various conditions, including atrial fibrillation, deep vein thrombosis (DVT), or plaque rupture, each of which can cause life-threatening events.

🔬Immediate treatment is required to dissolve or remove the clot, as tissue death begins within minutes to hours of complete blockage, especially in the brain or myocardium.

📌Core message

A blood clot is a leading cause of impaired perfusion due to sudden and complete obstruction of blood flow.

Answer 6

Correct Answers:

True

Rationale :

✅Emphysema is a type of chronic obstructive pulmonary disease (COPD), and it is not caused by infection or allergies but by long-term exposure to inhaled irritants, especially tobacco smoke.

🧬The pathophysiology involves destruction of alveolar walls, loss of elastic recoil, and air trapping, which leads to ineffective gas exchange.

🚭Infection and allergies may exacerbate symptoms but are not the primary etiology; rather, they are secondary contributors to disease progression.

📚Patient education should emphasize smoking cessation and avoiding environmental pollutants to slow down the irreversible damage to lung tissue.

📌Core message

Emphysema results from chronic exposure to irritants, especially smoking, and not from infections or allergies.

Answer 7

Correct Answers:

Tertiary

Rationale :

💊Tertiary prevention focuses on managing established disease and preventing complications or worsening of existing conditions.

🧠In clients with ineffective perfusion, prescribing antiplatelets and lipid-lowering agents is a strategy to prevent progression of atherosclerotic disease and reduce risk of thrombotic events.

📈This intervention comes after diagnosis and is aimed at reducing morbidity and mortality, particularly in clients with cardiovascular history.

🩺Understanding the levels of prevention helps the nurse educate clients appropriately and classify treatments based on their preventive intent.

📌Core message

Pharmacologic interventions like antiplatelets are part of tertiary prevention, aimed at managing existing disease and avoiding complications.

Answer 8

Correct Answers:

Family history of a myocardial infarction

Rationale :

🧬A family history of myocardial infarction is a nonmodifiable risk factor, meaning it is inherent and cannot be altered by lifestyle or treatment.

👨‍👩‍👦Genetics influence cholesterol metabolism, clotting tendencies, and overall cardiovascular vulnerability, which places individuals at higher risk even with a healthy lifestyle.

🔎Knowing a client’s family history allows for earlier risk screening, education, and preventive measures, especially for those with first-degree relatives affected.

📋While factors like smoking or stress can be modified, genetic predisposition remains unchanged and requires vigilant monitoring.

📌Core message

A family history of heart attack is a key nonmodifiable risk factor that increases an individual's cardiovascular risk.

Answer 9

Correct Answers:

Sickle Cell anemia

Rationale :

🧬Sickle cell anemia is an inherited genetic disorder that affects the structure of hemoglobin, specifically producing hemoglobin S instead of normal hemoglobin A.

🩸This abnormal hemoglobin causes red blood cells to take on a sickle shape, which leads to obstruction of small vessels and decreased oxygen delivery.

🧪The disease is autosomal recessive, meaning a child must inherit the defective gene from both parents to express the condition.

🧠Clients may experience vaso-occlusive crises, pain episodes, organ damage, and increased infection risk due to impaired circulation and chronic hemolysis.

📌Core message

Sickle cell anemia is a genetic disorder that alters red blood cell shape and function, leading to chronic perfusion issues.

Answer 10

Correct Answers:

Mothers transmit the disorder to their sons.

Rationale :

🧬Hemophilia is an X-linked recessive disorder, where the gene responsible for clotting factor deficiency is carried on the X chromosome.

👩Because males have only one X chromosome, inheriting the affected gene from their carrier mother results in disease expression.

🧑Fathers cannot pass hemophilia to their sons because they contribute a Y chromosome, not X, to male children.

🧠Understanding this inheritance pattern helps with genetic counseling, especially in families with known hemophilia cases.

📌Core message

Hemophilia is inherited in an X-linked pattern, with mothers passing the defective gene to their sons.
