Correct Answer: D

Rationale: The correct answer is D, the Western blot test with ELISA. First, ELISA is used as a screening test for HIV antibodies. If positive, a confirmatory test like Western blot is needed to detect specific antibodies. Western blot is highly specific and confirms the presence of HIV antibodies. E-rosette immunofluorescence is not typically used for HIV diagnosis. Quantification of T-lymphocytes is used to monitor disease progression in HIV but does not confirm HIV infection. ELISA alone is not confirmatory; it needs to be followed by a more specific test like Western blot.

Correct Answer:

Rationale: Correct Answer: B: Ask about the chief concerns or problems. Rationale: 1. This step follows setting the agenda to focus on patient's main issues. 2. Allows nurse to gather essential information for effective care. 3. Builds rapport and shows patient-centered approach. Summary of other choices: A: Introductions are typically done at the beginning of the interview. C: Prematurely ending the interview may hinder rapport and information gathering. D: Administering medications is not the immediate priority after setting the agenda.

Correct Answer: D

Rationale: Step 1: Levothyroxine (Synthroid) is the synthetic form of the thyroid hormone T4, the main hormone produced by the thyroid gland. Step 2: Levothyroxine is the preferred agent for thyroid hormone replacement therapy in hypothyroidism due to its stable and consistent potency. Step 3: Levothyroxine is well-absorbed by the body and has a long half-life, allowing for once-daily dosing. Step 4: Other choices are incorrect because Methimazole is used to treat hyperthyroidism, Livothyronine is a form of T3 hormone not commonly used for replacement therapy, and Thyroid USP dessicated is derived from animal thyroid glands and has inconsistent hormone content. Summary: Levothyroxine (Synthroid) is the preferred choice for thyroid hormone replacement therapy due to its synthetic nature, stable potency, good absorption, and long half-life. Other options are not

Correct Answer: D

Rationale: The correct answer is D: Hyperosmolar solutions used primarily to reverse negative nitrogen balance. Rationale: 1. Hyperalimentation solutions are designed to provide essential nutrients intravenously. 2. Hyperosmolar solutions have a higher osmolarity compared to body fluids, providing concentrated nutrition. 3. Negative nitrogen balance occurs when the body breaks down more protein than it synthesizes, requiring additional protein intake. 4. Hyperosmolar solutions can provide adequate protein and nutrients to reverse negative nitrogen balance. Summary: A: Hypotonic solutions do not increase osmotic pressure, but rather decrease it. B: Hypertonic solutions are not primarily used for hydration in this context. C: Alkalizing solutions are not the primary purpose of hyperalimentation and do not directly address cellular sweating.

Correct Answer: A

Rationale: The correct answer is A because a normal respiratory rate for an adult is typically between 12-20 breaths per minute. A respiratory rate of 18 falls within this range, indicating adequate respiratory function. Choice B is incorrect because an oxygen saturation of 91% is below the normal range of 95-100%, suggesting potential respiratory insufficiency. Choice C is incorrect as frank blood suction from the tube indicates a serious issue such as bleeding, not adequate respiratory condition. Choice D is also incorrect as the presence of a moderate amount of tracheobronchial secretions may indicate a respiratory infection or other respiratory issue, not necessarily adequate respiratory condition.
