The type of immunological protection provided by plasma therapy is

  • A. Natural active
  • B. Natural passive
  • C. Artificial active
  • D. Artificial passive
Correct Answer: D

Rationale: The correct answer is D: Artificial passive. Plasma therapy involves administering preformed antibodies to provide immediate protection against a specific pathogen. This is considered artificial passive immunity because the antibodies are obtained from an external source rather than being produced by the individual's immune system.

Explanation:
1. Natural active immunity (Choice A) is when the body produces its antibodies after exposure to a pathogen, which is not the case in plasma therapy.
2. Natural passive immunity (Choice B) is when antibodies are passed from mother to fetus or through breast milk, not obtained through plasma therapy.
3. Artificial active immunity (Choice C) involves vaccination to stimulate the body's immune response, which is different from plasma therapy.

In summary, the correct answer is D (Artificial passive) because plasma therapy provides immediate immunity through externally sourced antibodies, distinguishing it from the other types of immunological protection.

Hfr strains of bacteria:

  • A. do not have an 'F' (fertility) factor.
  • B. have an 'F' factor plasmid.
  • C. have an 'F' factor integrated in the bacterial chromosome.
  • D. transfer the genetic information to other bacteria with ow frequency.
Correct Answer: C

Rationale: The correct answer is C because Hfr strains of bacteria have the F factor integrated into their bacterial chromosome. This integration allows for the transfer of genetic material during conjugation. This integration results in a high frequency of genetic information transfer to recipient cells, which is a characteristic of Hfr strains.

Choice A is incorrect because Hfr strains do have the F factor, but it is integrated into their chromosome, not absent. Choice B is incorrect because Hfr strains do not just have an F factor plasmid; it is integrated into the chromosome. Choice D is incorrect because Hfr strains actually transfer genetic information with high frequency, not low frequency.

The patient in a long arm cast (from below the shoulder to the wrist, with a 90-degree elbow flexion) complains of a burning sensation over the elbow. The nurse's initial intervention should be:

  • A. Elevate the casted arm on pillows.
  • B. Check to see if the cast is properly supported.
  • C. Notify the charge nurse of developing pressure ulcer.
  • D. Cut a "window" in the cast.
Correct Answer: B

Rationale: The correct answer is B: Check to see if the cast is properly supported. The burning sensation over the elbow could indicate nerve compression due to improper cast positioning. By checking if the cast is properly supported, the nurse can ensure that there is no pressure on the nerves causing the burning sensation. Elevating the casted arm (choice A) may not address the root cause of the burning sensation. Notifying the charge nurse of developing pressure ulcer (choice C) is premature without confirming the cause of the burning sensation. Cutting a "window" in the cast (choice D) should be a last resort after ruling out other issues.

A male client is suspected of an immune system disorder. Which of the following important factors will the nurse document while assessing the client?

  • A. The client’s diet
  • B. The client’s drug history
  • C. The client’s ability to produce antibodies
  • D. The client’s family members’ history of chronic diseases
Correct Answer: B

Rationale: The client’s drug history is crucial as certain medications can affect immune function or mimic immune disorders.

Which antibody dominates the primary immune response?

  • A. IgG
  • B. IgA
  • C. IgM
  • D. IgE
Correct Answer: C

Rationale: The correct answer is C: IgM. During the primary immune response, IgM is the first antibody produced by the immune system in response to an antigen. IgM is efficient in agglutination and complement fixation, aiding in the elimination of pathogens. IgG is more prominent in the secondary immune response. IgA is mainly found in mucosal areas. IgE is associated with allergic reactions and parasitic infections, not the primary immune response. So, IgM dominates the primary immune response by being the initial antibody produced to combat antigens.

Which of the following is not a type of anemia?

  • A. Iron deficiency anemia
  • B. Sickle cell anemia
  • C. Aplastic anemia
  • D. Diabetes
Correct Answer: D

Rationale: The correct answer is D: Diabetes. Anemia is a condition characterized by a lack of healthy red blood cells or hemoglobin. Diabetes does not directly cause anemia; it is a metabolic disorder affecting blood sugar levels. Iron deficiency anemia (A) is caused by a lack of iron, sickle cell anemia (B) is a genetic disorder affecting red blood cells, and aplastic anemia (C) is a bone marrow disorder. Therefore, the other choices are types of anemia, while diabetes is not.
