Correct Answer: B

Rationale: In qualitative research, the focus is on exploring a phenomenon in-depth, understanding experiences, perceptions, and meanings. Unlike quantitative research, qualitative research does not typically start with a hypothesis to be tested. Instead, qualitative studies often use open-ended questions and flexible methods to gather rich, detailed data that can lead to new insights and theories. The other options - sample, literature review, and data collection - are essential components of the qualitative research process.

Correct Answer: A

Rationale: A nursing assistant can be delegated the task of changing wound dressings because it is considered a basic nursing care activity that does not require specialized training or knowledge. Nursing assistants are trained to perform tasks related to personal care, hygiene, and basic wound care under the supervision of a registered nurse. Changing wound dressings is a routine nursing task that can be safely delegated to a nursing assistant, allowing the nurse to focus on other aspects of patient care that require specialized nursing skills and knowledge.

Correct Answer: C

Rationale: Severe nausea and vomiting with a large volume of vomitus can indicate a serious underlying issue such as gastrointestinal obstruction or other medical emergencies. In this situation, it is crucial for the nurse to notify the physician immediately so that further assessment and appropriate management can be initiated promptly. Delay in seeking medical help can lead to complications and worsen the patient's condition. It is important to act quickly and involve the physician in situations where the patient's health may be at risk.

Correct Answer: C

Rationale: Subacute thyroiditis is an inflammatory disorder of the thyroid gland that causes gland destruction and release of pre-formed thyroid hormone leading to hyperthyroidism. The fine-needle aspiration biopsy findings of granulomatous inflammation and multinucleated giant cells are characteristic of subacute thyroiditis. This condition typically presents with a painful, tender thyroid gland and may be preceded by a viral illness. Unlike Graves' disease, which is an autoimmune disorder resulting in hyperthyroidism with diffuse goiter and positive thyroid stimulating immunoglobulins, subacute thyroiditis is typically self-limited and resolves spontaneously without the need for long-term treatment.

Correct Answer: D

Rationale: Before any procedure, it is crucial to ensure that you have the proper authorization and guidelines in place. By checking the physician's order and the patient care plan, you confirm that suctioning is indeed needed and that you follow the specific instructions for that patient. This step helps ensure patient safety and effective care delivery. Once you have verified this information, you can proceed with gathering equipment, performing hand hygiene, and assessing the patient's condition as necessary.
