Immunity to a disease after recovery is possible because the first exposure to the pathogen has stimulated the formation of which of the following?
- A. Antigens
- B. Complement
- C. Memory cells
- D. Natural killer cells
Correct Answer: C
Rationale: Immunity to a disease after recovery is possible because the first exposure to the pathogen has stimulated the formation of memory cells. Memory cells are a type of immune cell that "remembers" the specific pathogen encountered during the initial infection. When the same pathogen tries to infect the individual again, these memory cells quickly recognize the pathogen and mount a faster and stronger immune response, leading to a quicker recovery and preventing the person from getting sick again from the same pathogen. This immune memory is the basis of acquired immunity, providing long-lasting protection against future infections by the same pathogen.

Orchitis and sterility in male result as serious complication of
- A. rubella
- B. measles
- C. mumps
- D. diphtheria 126
Correct Answer: C
Rationale: Orchitis refers to the inflammation of the testicles, which can occur as a complication of mumps infection in males. Mumps is a viral infection caused by the mumps virus, and one of the common complications of mumps in males is orchitis. Orchitis can lead to testicular damage and potentially result in sterility if both testicles are affected. It is essential for males to receive the MMR (measles, mumps, rubella) vaccine to prevent mumps infection and its associated complications, including orchitis and sterility.
Which is an effective strategy to reduce the stress of burn dressing procedures?
- A. Give the child as many choices as possible.
- B. Reassure the child that dressing changes are not painful.
- C. Explain to the child why analgesics cannot be used.
- D. Encourage the child to master stress with controlled passivity.
Correct Answer: A
Rationale: Giving the child as many choices as possible is an effective strategy to reduce the stress of burn dressing procedures. Allowing the child to have some control over the situation can help them feel more empowered and less anxious. By giving choices, such as letting the child choose the order in which things are done or the type of dressing used, the child is more likely to feel a sense of autonomy and reduced stress during the procedure. This approach can help the child cope better with the dressing changes and make the experience more manageable for them.
When a client is receiving blood which of the ff nursing actions is essential to determine if chilling is the result of an emerging complication or of infusing cold blood?
- A. Monitoring the client's temperature before, during, and after transfusion
- B. Documenting the client's temp after the transfusion
- C. Documenting the temp of the blood before the transfusion
- D. Comparing the client's temp with the temp of the blood
Correct Answer: A
Rationale: Monitoring the client's temperature before, during, and after transfusion is essential to determine if chilling is the result of an emerging complication or of infusing cold blood. By consistently monitoring the client's temperature at different points in the transfusion process, healthcare providers can identify any significant changes that may indicate a complication. This allows for timely intervention and appropriate management of any issues related to the blood transfusion. Comparing the client's temperature with the temperature of the blood is important but alone it may not provide a comprehensive assessment of the client's condition during the transfusion process. So, the best course of action is to monitor the client's temperature at various time points to ensure accurate assessment and early detection of any complications.
