Correct Answer: B

Rationale: The correct answer is B: 2 to 3 weeks. Alopecia is a common adverse reaction to chlorambucil, a type of chemotherapy drug that can cause hair loss. Alopecia typically occurs around 2 to 3 weeks after the first administration of chlorambucil. This is because chemotherapy drugs affect rapidly dividing cells, including hair follicles. Hair loss is a well-known side effect of many chemotherapy drugs, and it is important for the nurse to educate the client about this potential side effect. Incorrect choices: A: Immediately - Hair loss does not occur immediately after the first administration of chlorambucil. C: 1 week - Hair loss typically occurs later than 1 week after starting chemotherapy. D: 1 month - While hair loss can occur within a month, it is more likely to happen sooner, around 2 to 3 weeks after starting the medication.

Correct Answer: C

Rationale: The correct answer is C: Helper T cells. Helper T cells play a crucial role in activating B cells by releasing cytokines that stimulate B cell proliferation and differentiation. They also help in the production of antibodies. Cytotoxic T cells (A) are involved in cell-mediated immunity, not humoral immunity. Suppressor T cells (B) regulate the immune response and do not directly assist in B cell activation. Neutrophils (D) are phagocytic cells involved in innate immunity, not in activating B cells in humoral immunity.

Correct Answer: A

Rationale: Step-by-step rationale for the correct answer (A): 1. Increased RBC: Hemolytic anemia leads to increased RBC production as the body compensates for the destruction of red blood cells. 2. Decreased bilirubin: Bilirubin levels decrease due to the accelerated breakdown of red blood cells. 3. Decreased Hgb and Hct: Hemolysis causes a decrease in hemoglobin and hematocrit levels as red blood cells are destroyed. 4. Increased reticulocytes: Reticulocytes are immature red blood cells released by the bone marrow in response to increased RBC destruction. Summary: - Choice B is incorrect as hemolytic anemia would lead to increased, not decreased, bilirubin levels. - Choice C is incorrect as hemolytic anemia would lead to decreased, not increased, Hgb and Hct levels. - Choice D is incorrect as hemolytic anemia would not lead to increased levels of all parameters

Correct Answer: B

Rationale: The correct answer is B because it acknowledges the patient's behavior is likely due to the stroke affecting his inhibitions. Finding a male assistant respects both the patient's dignity and the nursing assistant's comfort. Choice A is inappropriate as physical violence is never an acceptable response. Choice C lacks empathy and understanding of the situation. Choice D minimizes the seriousness of the behavior and fails to address the issue. B is the best option for promoting a safe and respectful environment for both the patient and staff.

Correct Answer: D

Rationale: The correct answer is D: Risk for body image disturbance. In Maslow's hierarchy, physiological needs like airway clearance take precedence over emotional or self-esteem needs like body image disturbance. Priority is given to addressing life-threatening issues first. Impaired urinary elimination could be related to the client's heart failure and should be addressed to prevent complications. Coping mechanisms are important for emotional well-being but are not as critical as physiological needs in this scenario.
