Correct Answer: A

Rationale: The correct answer is A: World Health Organization (WHO). The WHO is the primary organization responsible for global public health initiatives, coordinating international health efforts, setting norms and standards, providing technical support, and monitoring health trends. Choices B, C, and D are incorrect because while they play significant roles in health and global affairs, they do not have the primary responsibility for global public health like the WHO does.

Correct Answer: B

Rationale: After a water deprivation test in a client suspected of having diabetes insipidus, the nurse would expect the urine specific gravity to remain unchanged. This occurs because in diabetes insipidus, the kidneys are unable to concentrate urine, leading to a low urine specific gravity even after water deprivation. Choices A, C, and D are incorrect. Increased edema and weight gain are not typical findings in diabetes insipidus. Rapid protein excretion is not directly related to the condition, and decreased blood potassium is not a common outcome of a water deprivation test for diabetes insipidus.

Correct Answer: C

Rationale: The correct answer is C: 'The stomach contents and air must be drained first.' Before starting feedings through a gastrostomy tube, it is essential to drain the stomach contents and air. This process helps prevent complications and ensures the proper functioning of the tube after placement. Choice A is incorrect because initiating feedings within 5 to 7 days may lead to complications if the stomach is not adequately prepared. Choice B is incorrect as feeding should not begin immediately to allow for proper preparation of the tube and the stomach. Choice D is incorrect because although incision healing is important, draining the stomach contents and air is a more immediate concern to prevent complications.

Correct Answer: A

Rationale: The correct answer is A. A patient with known COPD and difficulty breathing after physical exertion like climbing stairs requires immediate assessment by the nurse. This could indicate a potential exacerbation of COPD, which needs prompt intervention to prevent respiratory distress. Choices B, C, and D describe important patient situations that also require attention, but the urgency is higher with a COPD patient experiencing difficulty breathing.

Correct Answer: A

Rationale: Identifying available resources and services is the priority action when developing a disaster response plan. This step is crucial as it helps the community understand what resources and services are already in place and what additional support may be needed during a disaster. Conducting disaster drills, educating the community about disaster preparedness, and developing a communication plan are important steps in disaster preparedness but come after identifying available resources and services. Without knowing the available resources, it would be challenging to effectively plan and respond to a disaster.
