Nursing Question Q2721. Which cereal protein is deficient in lysine but rich in methionine?

A. Rice
B. Wheat
C. Maize
D. Millets

Which Cereal Protein is Deficient in Lysine but Rich in Methionine?

Cereal proteins often lack certain essential amino acids. Maize protein (zein) is a classic example tested in nutrition exams.

Why is Maize Correct?

✅ Maize is deficient in:

Lysine
Tryptophan

But it is relatively rich in methionine, a sulfur-containing essential amino acid.

Because of this imbalance, diets based mainly on maize may require supplementation with other protein sources, such as pulses, to improve protein quality.

Why Are the Other Options Wrong?

❌ Rice is low in lysine but is not the classical answer to this question.

❌ Wheat is also deficient in lysine but is not particularly known for being rich in methionine.

❌ Millets have varying amino acid compositions and are not the standard answer.

Final Answer✅ C. Maize

Nursing Question 2718. Site of growth in the length of a long bone is:

(a) Diaphysis
(b) Periosteum
(c) Epiphyseal plate
(d) Bone marrow

How Does a Long Bone Increase in Length?

Long bones grow in length through the process of endochondral ossification, which occurs at a specialized growth area between the epiphysis and diaphysis.

Why is Epiphyseal Plate Correct?

✅ The epiphyseal plate (growth plate) is the site responsible for the longitudinal growth of long bones.

It is a layer of hyaline cartilage located between the:

Epiphysis (end of the bone)
Diaphysis (shaft of the bone)

As cartilage cells multiply and are replaced by bone tissue, the bone increases in length.

Why Are the Other Options Wrong?

❌ Diaphysis is the shaft of the bone but is not the growth center for length.

❌ Periosteum contributes to the increase in bone thickness (appositional growth), not length.

❌ Bone marrow is involved in blood cell production and is not responsible for bone length growth.

Final Answer✅ (c) Epiphyseal plate

Nursing Question 2715. Which disease is characterized by a "slapped cheek" appearance?

A. Rubella
B. Measles
C. Erythema infectiosum
D. Roseola infantum

What is the "Slapped Cheek" Disease?

The classic "slapped cheek" appearance refers to bright red cheeks that look as if the child has been slapped.

This characteristic rash is seen in Erythema infectiosum, also known as Fifth disease.

Why is Erythema Infectiosum Correct?

✅ Erythema infectiosum is caused by Parvovirus B19.

Typical Features:
Bright red "slapped cheek" rash on the face
Lacy, reticular rash on the trunk and limbs
Mild fever
Malaise
Common in school-age children

The facial rash is highly characteristic and often helps make the diagnosis.

Why Are the Other Options Wrong?

❌ Rubella causes a pink maculopapular rash and lymphadenopathy, not a slapped-cheek appearance.

❌ Measles causes fever, cough, coryza, conjunctivitis, and a widespread rash.

❌ Roseola infantum typically presents with a high fever followed by a rash after the fever subsides.

Final Answer✅ C. Erythema infectiosum

See Answer of Nursing Question 2711. Haversian canal situated into:

(a) Bone
(b) Brain
(c) Lungs
(d) Kidney

What is the Haversian Canal?

The Haversian canal (central canal) is a microscopic channel found in the compact bone.

It is part of the Haversian system (osteon) and contains:

Blood vessels
Nerves
Lymphatic vessels

These structures help nourish and maintain bone tissue.

Why is Bone Correct?

✅ Haversian canals are located in bone, specifically in the compact bone of long bones and other skeletal structures.

They run longitudinally through the center of each osteon.

Why Are the Other Options Wrong?

❌ Brain does not contain Haversian canals.

❌ Lungs contain bronchi and alveoli, not Haversian systems.

❌ Kidney contains nephrons, not Haversian canals.

Final Answer✅ (a) Bone

Nursing Question 2709. The leakage of blood backwards through the mitral valve each time the left ventricle of the heart contracts, is known as:

(a) Mitral regurgitation
(b) Mitral prolapse
(c) Mitral stenosis
(d) Mitral systole

What is Mitral Regurgitation?

The mitral valve lies between the left atrium and left ventricle.

Normally, it closes tightly during ventricular contraction (systole) to prevent blood from flowing backward.

Why is Mitral Regurgitation Correct?

✅ Mitral regurgitation occurs when the mitral valve does not close properly, allowing blood to leak backward from the left ventricle into the left atrium during systole.

This backward flow is called regurgitation.

Common Symptoms
Shortness of breath
Fatigue
Palpitations
Heart murmur
Why Are the Other Options Wrong?

❌ Mitral prolapse is the bulging of the mitral valve leaflets into the left atrium during systole. It may cause regurgitation but is not the leakage itself.

❌ Mitral stenosis is narrowing of the mitral valve opening, restricting blood flow from the left atrium to the left ventricle.

❌ Mitral systole is not a recognized valvular disorder.

Easy Memory Trick
❤️ Regurgitation = Reverse Flow

Think:
Mitral Valve Leaks Backward → Mitral Regurgitation

Final Answer✅ (a) Mitral regurgitation

Nursing Question 2706. Which type of inflammation is charac-terized by granuloma formation?

A. Acute inflammation
B. Serous inflammation
C. Chronic inflammation
D. Fibrinous inflammation

What is Granulomatous Inflammation?

Granulomatous inflammation is a specialized form of chronic inflammation characterized by the formation of granulomas.

A granuloma is a collection of:

Modified macrophages (epithelioid cells)
Giant cells
Lymphocytes

It develops when the body attempts to wall off substances that are difficult to eliminate.

Why is Chronic Inflammation Correct?

✅ Granuloma formation is a hallmark of chronic inflammation.

Common conditions associated with granulomatous inflammation include:

Tuberculosis
Leprosy
Sarcoidosis
Fungal infections
Why Are the Other Options Wrong?

❌ Acute inflammation is characterized by neutrophil infiltration and rapid onset, not granuloma formation.

❌ Serous inflammation produces a thin, watery exudate, such as in blisters.

❌ Fibrinous inflammation is characterized by fibrin deposition on tissues and serous membranes.

Final Answer✅ C. Chronic inflammation

Nursing Question 2703. The bronchial tree ends in:

A. Tertiary bronchi
B. Bronchioles
C. Terminal bronchioles
D. Alveoli

What is the Bronchial Tree?

The bronchial tree is the branching system of airways that carries air from the trachea into the lungs.

The pathway is:

Trachea → Primary bronchi → Secondary bronchi → Tertiary bronchi → Bronchioles → Terminal bronchioles → Respiratory bronchioles → Alveoli

Why is Terminal Bronchioles Correct?

✅ The bronchial tree ends at the terminal bronchioles.

Terminal bronchioles are the last part of the conducting zone, where air is transported but gas exchange does not occur.

Beyond the terminal bronchioles begins the respiratory portion of the lungs:

Respiratory bronchioles
Alveolar ducts
Alveolar sacs
Alveoli
Why Are the Other Options Wrong?

❌ Tertiary bronchi continue branching into smaller airways.

❌ Bronchioles are a broad category that includes terminal bronchioles.

❌ Alveoli are the sites of gas exchange and belong to the respiratory zone, not the bronchial tree itself.

Final Answer✅ C. Terminal bronchioles

See Answer-
Nursing Question 2700. Which injectable route is commonly used when venous access cannot be established rapidly during an emergency?

A. Intradermal
B. Subcutaneous
C. Intraosseous
D. Intra-articular

What is the Intraosseous Route?

✅ Intraosseous (IO) route involves inserting a needle directly into the bone marrow cavity.

The bone marrow has a rich blood supply, allowing fluids and medications to enter the circulation quickly when intravenous access is difficult or impossible.

Common Sites
Proximal tibia
Distal tibia
Proximal humerus
Sternum (in selected devices)
Why is Intraosseous Correct?

✅ IO access is commonly used in emergencies when rapid venous access cannot be established.

It provides a fast and reliable route for:

IV fluids
Blood products
Emergency medications
Why Are the Other Options Wrong?

❌ Intradermal is used for skin tests such as the tuberculin test.

❌ Subcutaneous injections are absorbed slowly and are not suitable for emergency resuscitation.

❌ Intra-articular injections are administered into a joint space and are not used for emergency vascular access.

Final Answer✅ C. Intraosseous

Nursing Question 2697. Heat stroke occurs when body temperature is:

(a) 98.6-100°F
(b) 100-102°F
(c) 102-104°F
(d) above 104°F

What is Heat Stroke?

Heat stroke is a life-threatening condition that occurs when the body's temperature regulation fails, causing a dangerously high core body temperature.

It is a medical emergency that requires immediate treatment.

Why is "Above 104°F" Correct?

✅ Heat stroke is typically defined as a body temperature above 104°F (40°C).

At this temperature, the body can no longer effectively cool itself, leading to:

Hot, dry skin (or heavy sweating in exertional heat stroke)
Confusion
Dizziness
Seizures
Loss of consciousness

Without prompt treatment, heat stroke can cause organ damage and death.

Why Are the Other Options Wrong?

❌ 98.6–100°F is within the normal to slightly elevated range.

❌ 100–102°F indicates a mild fever, not heat stroke.

❌ 102–104°F may represent a high fever or heat exhaustion, but heat stroke is generally diagnosed when the temperature exceeds 104°F.

Final Answer✅ (d) Above 104°F
