Correct Answer: D

Rationale: During times of staff and financial shortage, the Modular Method is considered the best and most effective. This method allows for flexibility and adaptability in assigning tasks and responsibilities, making it easier to cope with limited resources. Functional Method (Choice A) focuses on the division of labor based on each staff member's skills, which may not be the most efficient during shortages. Primary Nursing (Choice B) and Team Nursing (Choice C) may require a more significant number of staff, making them less suitable during shortages.

Correct Answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

Correct Answer: A

Rationale: In the scenario described, when a patient is unconscious and unable to provide consent, the responsibility usually falls on the physician to make decisions regarding the patient's treatment, including obtaining consent for an operation. While nurses play a crucial role in patient care, they typically do not have the authority to provide consent for a major procedure. The next of kin may be consulted for input, but the ultimate decision-making authority lies with the physician. The patient, being unconscious, is unable to provide consent in this situation.

Correct Answer: C

Rationale: Iodine is the correct answer. It is crucial for the synthesis of thyroid hormones by the thyroid gland. Without sufficient iodine, the thyroid cannot produce adequate amounts of hormones, leading to potential issues like hypothyroidism. Iron (Choice A), Zinc (Choice B), and Magnesium (Choice D) do not play a direct role in the synthesis of thyroid hormones, making them incorrect choices for this question.

Correct Answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.
