Rationale: In humoral immunity, the activation of B cells is facilitated by helper T cells. Helper T cells play a crucial role in coordinating the immune response by interacting with B cells. They secrete cytokines that stimulate B cells to proliferate and differentiate into antibody-secreting plasma cells. Without the assistance of helper T cells, the activation of B cells and the production of antibodies would be impaired. Cytotoxic T cells are involved in cell-mediated immunity, supressor T cells regulate immune response, and neutrophils are involved in phagocytosis and innate immunity, but they do not directly assist in B cell activation in humoral immunity.

Correct Answer: B

Rationale: A latex condom with spermicide provides the best protection against HIV transmission during sexual intercourse. Safer sex practices for persons with HIV involve using condoms consistently and correctly during every sexual encounter to reduce the risk of HIV transmission to partners, regardless of their HIV status. Spermicide, while offering additional protection against pregnancies, does not provide additional protection against HIV transmission. Other contraceptive methods like birth control pills, implants, and injections are not effective in preventing HIV transmission. The intrauterine device is also not specifically recommended for clients with HIV as it does not provide protection against HIV transmission during sexual activities.

Correct Answer: C

Rationale: The nurse would first assess for an irregular heart rate and rhythm. In a 4-month old infant with a congenital heart defect experiencing marked dyspnea at rest, the sudden onset of cyanosis (blue coloration) and increased respiratory rate can indicate worsening heart failure and potential arrhythmias. Assessing for any abnormal heart rhythms is a priority to determine if immediate intervention is required to stabilize the infant's condition and prevent further deterioration.

Correct Answer: A

Rationale: Play serves as a method to assist disturbed children by providing them with a therapeutic outlet to express themselves and work through their emotions in a safe and constructive manner.
