Correct Answer: A

Rationale: The correct answer is A: Decreased serum sodium level. In SIADH, there is an excessive release of ADH, causing water retention and dilution of sodium in the blood. This leads to hyponatremia. B: Increased blood urea nitrogen and C: Decreased serum creatinine level are not typically associated with SIADH. D: Increased hematocrit is not a typical finding in SIADH, as it is more related to dehydration. Therefore, the most anticipated laboratory test result in a client with SIADH is a decreased serum sodium level due to dilutional hyponatremia.

Correct Answer: B

Rationale: The correct answer is B: Patient expectations. During a nursing health history, the nurse focuses on gathering information about the patient's health concerns, medical history, lifestyle, and expectations for their care. Addressing patient expectations is crucial for providing patient-centered care and establishing a therapeutic relationship. The other choices are incorrect because: A: Nurse's concerns are not the primary focus of a nursing health history. C: Current treatment orders are important but are typically addressed during a physical assessment or when implementing care. D: Nurse's goals for the patient are important but should be developed in collaboration with the patient based on their needs and preferences.

Correct Answer: A

Rationale: The correct answer is A: 2 L/min. In emphysema, there is impaired gas exchange due to damaged lung tissue, resulting in decreased oxygen levels. Administering too high a flow rate can lead to oxygen toxicity. The standard oxygen therapy for emphysema is 1-2 L/min to maintain oxygen saturation without causing harm. Higher flow rates like 10 L/min (B) and 6 L/min (C) are excessive and can lead to oxygen toxicity. 95 L/min (D) is dangerously high and not suitable for oxygen therapy in emphysema. Therefore, A is the correct choice for safe and effective oxygen administration in emphysema.

Correct Answer: D

Rationale: Step 1: The correct answer is D because it emphasizes the importance of medical examination and diagnostic testing to determine if the man has an STD. Step 2: Visual inspection (choice B) is not reliable as some STDs may not present with visible symptoms. Step 3: Relying solely on appearance and condom use (choices A and C) does not guarantee protection against all STDs. Step 4: Choice D is the best option as it advocates for seeking professional medical advice for accurate diagnosis and treatment.

Correct Answer: A

Rationale: The correct answer is A because signs of brain injury, such as altered level of consciousness, unequal pupil size, and clear fluid draining from the nose or ears, indicate a need for urgent medical attention. Choice B is incorrect because hemorrhaging from the oral cavity is not a common sign of a skull fracture. Choice C is incorrect as elevating the foot of the bed is not appropriate for a skull fracture but may be done for shock. Choice D is incorrect because decreased intracranial pressure and temperature are not typical symptoms of a skull fracture.
