Correct Answer: A

Rationale: The correct answer is A: Human Needs (Maslow) model. The nurse is using a systematic approach based on Maslow's Hierarchy of Needs, which includes physiological, safety, love/belonging, esteem, and self-actualization needs. This model organizes assessment data by prioritizing these universal life requirements. Incorrect choices: B: Functional Health Patterns model - This model focuses on 11 functional health patterns, not the hierarchy of universal life requirements. C: Human Response Patterns model - This model focuses on the individual's response to stressors, not prioritizing universal life requirements. D: Body System model - This model focuses on assessing specific body systems, not the holistic approach of addressing all life requirements.

Correct Answer: B

Rationale: The correct answer is B: radiation therapy. Radiation therapy uses high-energy radiation to target and destroy cancer cells while minimizing damage to surrounding healthy tissues. It is a localized treatment that is effective in shrinking tumors and preventing cancer cell growth. Surgery (A) involves physically removing the tumor and surrounding tissues, while chemotherapy (C) uses drugs to kill cancer cells throughout the body. Palliative treatment (D) focuses on symptom management and improving quality of life in advanced stages of cancer. In this case, the focus is on a form of cancer therapy involving high-energy electromagnetic radiation, making radiation therapy the most appropriate choice.

Correct Answer: A

Rationale: Rationale: The correct answer is A, overstimulation of the parathyroid hormone. After a thyroidectomy, there is a risk of unintentional damage to the parathyroid glands, leading to hypoparathyroidism. Circumoral tingling, positive Chvostek’s sign, and positive Trousseau’s sign are classic signs of hypocalcemia resulting from parathyroid insufficiency. Choices B, C, and D are incorrect because they do not explain the specific symptoms observed in Emil, which are indicative of low calcium levels due to parathyroid dysfunction.

Correct Answer: B

Rationale: To calculate the mL needed for the injection, divide the prescribed dose by the concentration of the medication. In this case, 30 mg ÷ 50 mg/mL = 0.6 mL. However, since the nurse should round up to ensure the full dose is administered, the correct answer is 0.7 mL. Choice A is incorrect as it is rounded down. Choice C is incorrect as it is the exact division without rounding up. Choice D is incorrect as it is rounded up too much.

Correct Answer: C

Rationale: The correct answer is C: Performing a physical examination. This method allows the nurse to gather objective data directly from the patient's body, such as vital signs, skin condition, and overall health status. It provides a comprehensive overview of the patient's current health status and helps in establishing a baseline for further assessments and interventions. Reviewing literature (A) is important for evidence-based practice but does not directly establish a patient's database. Checking orders for tests (B) is essential but does not provide a holistic view of the patient. Ordering medications (D) is a treatment intervention and not a data collection method.
