What is the role of pattern recognition in innate immunity, as proposed by Janeway?

  • A. Specific recognition of antigens
  • B. Binding toxins to create immunity
  • C. Identifying common pathogen-associated molecular patterns
  • D. Suppressing lymphocyte activation
Correct Answer: C

Rationale: Pattern recognition in innate immunity, as proposed by Janeway, involves identifying common pathogen-associated molecular patterns (PAMPs). This is crucial for initiating the immune response against pathogens. PAMPs are specific molecular patterns found on pathogens but not on host cells. By recognizing these patterns, the innate immune system can quickly and effectively identify potential threats and trigger the appropriate immune response.

Explanation of why other choices are incorrect:
A: Specific recognition of antigens is a function of adaptive immunity, not innate immunity.
B: Binding toxins to create immunity is not the primary role of pattern recognition in innate immunity.
D: Suppressing lymphocyte activation is not the role of pattern recognition in innate immunity; rather, it is involved in activating immune responses against pathogens.

Which of the following is not required for full activation of a naïve lymphocyte?

  • A. Migration into an inflammatory site
  • B. Costimulatory signalling
  • C. Cytokines
  • D. Recognition of specific antigen
Correct Answer: A

Rationale: The correct answer is A. Naïve lymphocytes require activation through recognition of specific antigen, costimulatory signaling, and cytokines. Migration into an inflammatory site is not a requirement for full activation. Naïve lymphocytes can be activated in secondary lymphoid organs where antigen presentation occurs. Migration to inflammatory sites occurs after activation to fight infections.

A small lesion is discovered in a patient’s lung when an x-ray is performed for cervical spine pain. What is the definitive method of determining if the lesion is malignant?

  • A. Lung scan
  • B. Tissue biopsy
  • C. Oncofetal antigens in the blood
  • D. CT or positron emission tomography (PET) scan
Correct Answer: B

Rationale: Tissue biopsy provides definitive diagnosis by examining the lesion's cellular characteristics.

the characteristic of blood types AB is

  • A. a general receptor
  • B. a general donor
  • C. a receptor and donor
  • D. neither donating nor receptor
Correct Answer: A

Rationale: The correct answer is A: a general receptor. Blood type AB individuals have both A and B antigens on their red blood cells, making them universal recipients since they can receive blood from all blood types without rejection. This is because they have no antibodies against A or B antigens. The other choices are incorrect because blood type AB individuals cannot be universal donors (choice B) as they have both A and B antigens, not making them suitable for all recipients. They are not both a receptor and donor (choice C) as they can only receive blood from all types, not donate to all. Lastly, they are not neither donating nor a receptor (choice D) since they can receive blood from all types, making them a receptor.

A nurse caring for clients with systemic lupus erythematosus (SLE) plans care understanding the most common causes of death for these clients is which of the following? (Select one that does not apply.)

  • A. Infection
  • B. Cardiovascular impairment
  • C. Vasculitis
  • D. Chronic kidney disease
Correct Answer: C

Rationale: The correct answer is C: Vasculitis. Vasculitis is a common complication of systemic lupus erythematosus (SLE) and can lead to serious organ damage and even death. In SLE, inflammation affects blood vessels, leading to vasculitis which can cause tissue damage and impaired blood flow. While infections, cardiovascular impairment, and chronic kidney disease are also common causes of mortality in SLE patients, vasculitis is specifically associated with the disease and its complications. Infections can occur due to the immune system's weakened response, cardiovascular issues can arise from inflammation and damage to the heart and blood vessels, and chronic kidney disease can develop due to immune complex deposition in the kidneys. However, vasculitis is the most directly linked cause of death in SLE patients due to its impact on multiple organ systems.

Which of the following is the best dietary advice to maximize the immune function in healthy people?

  • A. To include immune-enhancing formulas.
  • B. To avoid polyunsaturated fatty acids.
  • C. To increase intake of essential fatty acids and omega-3 fatty acids.
  • D. To follow a balanced and varied diet.
Correct Answer: D

Rationale: A balanced and varied diet ensures the intake of all necessary nutrients that support optimal immune function.
