Correct Answer: C

Rationale: Rationale for Correct Answer (C): Asking the NAP to record the patient's vital signs before administering medications is the correct clinical decision. Vital signs are crucial indicators of a patient's health status and should be documented before any interventions. By having the NAP record the vital signs, the nurse ensures that the patient's condition is properly assessed and monitored. This action aligns with the standard of care and promotes patient safety. Summary of Incorrect Choices: A: Administering medications without knowing the patient's vital signs could be dangerous, especially if there are abnormalities that need attention. B: Reviewing vital signs upon return delays necessary assessment and intervention, potentially compromising patient safety. D: Omitting vital signs without assessment puts the patient at risk, as changes in vital signs can indicate underlying issues that need immediate attention.

Correct Answer: A

Rationale: The correct answer is A because thalassemia is a genetic blood disorder that can cause anemia and fatigue. By maintaining the client on bed rest and protecting them from infections, we can help prevent complications such as fatigue and infections due to reduced red blood cell production. Ambulating the client frequently (choice B) may lead to increased fatigue and risk of injury. Advising to drink 3 quarts of fluid per day (choice C) is not specific to thalassemia treatment and could potentially worsen symptoms. Instructing the client to elevate lower extremities (choice D) is not directly related to managing thalassemia and may not provide significant benefits in this context.

Correct Answer: A

Rationale: The correct answer is A because protocols are indeed guidelines that assist clinicians in decision-making and choosing interventions for specific health care problems. This definition accurately reflects the purpose and function of protocols in nursing practice. Option B is incorrect as it describes protocols as policies related to nurses' duties and standards of care, which is more aligned with job descriptions and policies rather than protocols. Option C is incorrect as it relates protocols to a code of ethics, which is a separate concept that guides ethical decision-making and behavior in nursing practice. Option D is incorrect as it inaccurately describes protocols as prescriptive order forms, which are actually separate from protocols and are used for medication administration and treatment orders.

Correct Answer: D

Rationale: The correct answer is D: Papillary carcinoma. This is the most common form of thyroid cancer in adults, accounting for about 80% of cases. It is typically slow-growing and has a good prognosis. Papillary carcinoma arises from the follicular cells of the thyroid gland. Follicular carcinoma (choice A) is less common than papillary carcinoma and arises from the follicular cells as well. Anaplastic carcinoma (choice B) is a highly aggressive and rare form of thyroid cancer. Medullary carcinoma (choice C) originates from the parafollicular C cells of the thyroid gland and is not as common as papillary carcinoma. Therefore, the most appropriate choice is D, papillary carcinoma, due to its high prevalence and relatively favorable prognosis.

Correct Answer: B

Rationale: The correct answer is B: Suppressor T cells. Suppressor T cells regulate the immune response by inhibiting the activity of other immune cells to prevent overreaction and maintain immune balance. They play a crucial role in preventing autoimmune diseases and excessive inflammation. Plasma cells (A) produce antibodies, Helper T cells (C) assist in activating other immune cells, and B lymphocytes (D) are involved in antibody production. Suppressor T cells specifically have the function of shutting down immune responses, making them the immune system’s shutoff mechanism.
