Question

What disease is transmitted via vector-borne transmission?

Answer 1

Correct Answers:

Malaria

Rationale :

⭐ Vector-borne transmission occurs when an infectious disease is spread through an intermediate carrier (vector), often an insect such as a mosquito, flea, or tick.

⭐ Malaria is a classic example, transmitted by the bite of an infected Anopheles mosquito, which carries the Plasmodium parasite.

⭐ In contrast, influenza and measles are spread via droplet or airborne transmission, while syphilis is spread through direct sexual contact (bodily fluids).

⭐ Recognizing the transmission route is vital for implementing appropriate prevention strategies (e.g., mosquito nets, repellents, and spraying for malaria).

⭐ Nurses use this knowledge for infection control education and community health promotion in endemic areas.

Answer 2

Correct Answers:

A tendency that promotes the development of a disease

Rationale :

⭐ A predisposing factor is a condition or characteristic that makes a person more susceptible to developing a disease.

⭐ Examples include age, gender, genetics, diet, or occupational exposure.

⭐ These factors do not directly cause disease but increase the likelihood of its occurrence when other conditions are present.

⭐ Differentiating between predisposing factors and triggers is key—triggers initiate acute episodes, while predisposing factors set the stage.

⭐ Understanding this helps nurses identify at- risk populations for early prevention strategies.

Answer 3

Correct Answers:

A person with sores on their leg that are not healing

Rationale :

⭐ Non-healing sores may indicate abnormal cell growth and are a red flag for possible cancer.

⭐ Early detection is essential for effective treatment and better outcomes.

⭐ A productive cough with influenza is expected and self-limiting, not cancer-related.

⭐ Weight loss after dieting is intentional, while freckles are benign skin features.

⭐ Nurses should encourage individuals with chronic, unexplained changes to seek medical screening.

Answer 4

Correct Answers:

Immunity that develops after receiving antibodies

Rationale :

⭐ Passive immunity occurs when a person is given ready-made antibodies rather than producing them through their own immune system.

⭐ Examples include maternal antibodies passed via the placenta or immunoglobulin therapy.

⭐ It provides immediate but temporary protection, unlike active immunity which lasts longer.

⭐ Vaccinations produce active artificial immunity, not passive.

⭐ Recognizing types of immunity helps guide nursing teaching on prevention vs. treatment protection

Answer 5

Correct Answers:

Increased blood glucose

Rationale :

⭐ During stress, cortisol is released from the adrenal cortex, stimulating gluconeogenesis, which raises blood glucose.

⭐ This ensures energy supply for the “fight-or-flight” response.

⭐ Cortisol also suppresses the immune system but does not directly cause bronchodilation (that is adrenaline’s role).

⭐ It does not directly increase blood volume, though it may influence sodium retention indirectly.

⭐ High cortisol over time can lead to hyperglycemia, insulin resistance, and risk of diabetes.

Answer 6

Correct Answers:

Primary

Rationale :

⭐ Primary prevention focuses on preventing disease before it occurs, such as vaccinations, health education, and lifestyle changes.

⭐ Receiving the influenza vaccine prevents infection altogether, fitting into this category.

⭐ Secondary prevention involves early detection (e.g., screening), and tertiary prevention involves rehabilitation after disease.

⭐ Quaternary prevention refers to avoiding unnecessary interventions.

⭐ Nurses promote primary prevention to maintain population health and reduce disease burden.

Answer 7

Correct Answers:

Intellectual disability

Rationale :

⭐ Individuals with Down syndrome commonly have intellectual disability, with varying degrees of learning and developmental delay.

⭐ They often have characteristic facial features, hypotonia, and congenital heart defects.

⭐ They do not typically have exceptional memory or high IQ, and advanced language skills are not common.

⭐ Early intervention programs and therapies help maximize functional potential.

⭐ Recognizing this helps nurses provide appropriate education and support for families.

Answer 8

Correct Answers:

Mast cells release chemical mediators like histamine.

Rationale :

⭐ Mast cells are immune cells that release histamine and other mediators during inflammatory and allergic responses.

⭐ Histamine causes vasodilation, increased vascular permeability, and bronchoconstriction, producing allergy symptoms.

⭐ They are not antibodies, proteins, or direct antigen destroyers but mediator cells.

⭐ Their activation is central in anaphylaxis and allergic reactions.

⭐ Nurses must be alert to the role of mast cells in hypersensitivity responses.

Answer 9

Correct Answers:

Active natural

Rationale :

⭐ Immunity developed after having a disease is active natural immunity because the body produces antibodies in response to the infection.

⭐ This provides long-lasting protection as memory cells are formed.

⭐ Vaccinations provide active artificial immunity, while receiving antibodies provides passive immunity.

⭐ Understanding this distinction supports accurate teaching on how immunity is acquired.

⭐ It also explains why childhood illnesses such as measles or chickenpox often provide lifelong immunity.

Answer 10

Correct Answers:

Severely damaged skin extending to the muscles and bones

Rationale :

⭐ Stage 4 pressure injuries represent the deepest form, with full-thickness skin and tissue loss extending into muscle, tendon, or bone.

⭐ Stage 1 shows non-blanchable redness, Stage 2 partial-thickness skin loss, and Stage 3 damage into adipose tissue.

⭐ Stage 4 may also present with slough or eschar, but the defining feature is exposure of underlying structures.

⭐ These injuries are severe and carry high risk for osteomyelitis and systemic infection.

⭐ Prevention and early detection at earlier stages are critical to avoid progression.
