Correct Answer: B

Rationale: The nurse's best approach to address the patient's fear of needles before a blood draw is to provide the patient with information about relaxation techniques and distraction methods (Option B). Dismissing the patient's fear (Option A), ignoring the fear and proceeding quickly (Option C), or telling the patient that the fear is irrational and unfounded (Option D) would not be helpful and could potentially escalate the patient's anxiety. Providing information on relaxation techniques such as deep breathing or visualization, as well as distraction methods like listening to music or engaging in conversation, can help the patient feel more comfortable and reduce their fear and anxiety during the blood draw procedure. It is important for the nurse to acknowledge and address the patient's concerns in a supportive and empathetic manner to build trust and ensure a successful blood draw experience.

Correct Answer: B

Rationale: A "full understanding" in research should be understood by the nurse researcher as explaining the study including risks and ben . When conducting research involving participants, it is crucial for nurse researchers to provide all necessary information about the study, including potential risks and benefits, in a clear and understandable manner. This ensures that participants are well-informed and can make informed decisions about their participation. By explaining the study thoroughly, nurse researchers uphold ethical principles such as informed consent and respect for participants' autonomy. It also helps in building trust between the researcher and participants, ultimately leading to more reliable and ethical research outcomes.

Correct Answer: B

Rationale: The diagnostic test that could be useful in confirming the diagnosis of Dengue Fever is the ELISA test. ELISA stands for Enzyme-Linked Immunosorbent Assay. This test detects the presence of dengue virus-specific antibodies (IgM and IgG) in the blood of an individual suspected to have dengue fever. Elevated levels of these antibodies indicate a recent or ongoing dengue virus infection. ELISA is a standard and reliable test used in diagnosing dengue fever, along with clinical symptoms and other laboratory tests.

Correct Answer: A

Rationale: The patient's presentation with a blood sugar level of 800mg/dL, absence of ketones in the urine, dehydration, and altered mental status points towards Hyperosmolar nonketotic coma (HNKC). HNKC typically occurs in patients with Type 2 diabetes and is characterized by extremely high blood glucose levels (hyperglycemia) without significant ketosis. The absence of ketones in the urine distinguishes HNKC from Diabetic ketoacidosis (DKA). Patients with HNKC often present with severe dehydration, altered mental status, and hyperosmolarity. It is crucial to address the underlying cause of the hyperglycemia, correct dehydration, and normalize blood glucose levels promptly in the management of HNKC.

Correct Answer: B

Rationale: The patient can tell all information to the nurse once the feeling of security is established in the nurse-patient relationship. Open communication and sharing of information are essential components of nursing care. Patients are more likely to disclose personal information, concerns, and feelings when they trust their nurse and feel secure in the relationship. Building trust and creating a safe and supportive environment are crucial for effective therapeutic communication and holistic patient care. It is important for the nurse to establish a trusting relationship with the patient to encourage open communication and provide patient-centered care.
