Correct Answer: B

Rationale: The correct answer is B: 'Organize an immunization clinic for at-risk members of the community.' The assurance function of public health involves ensuring that essential public health services, like immunizations, are provided to meet public health goals. Choice A, collecting data on health trends, is more aligned with the assessment function of public health. Choice C, developing policies to address health disparities, pertains to the policy development function. Choice D, conducting research on communicable diseases, is related to the research function rather than the assurance function.

Correct Answer: B

Rationale: The correct action for the nurse to take to prevent contamination during a sterile dressing change is to restart the procedure if the sterile solution splashes onto the sterile field. Any contamination of the sterile field compromises the aseptic technique and increases the risk of infection for the client. Therefore, it is crucial to maintain the sterility of the field throughout the procedure. Choices A, C, and D are incorrect because proceeding with the dressing change, continuing without concern for minor splashes, or delegating the task to another nurse would all compromise the sterility of the procedure and increase the risk of infection for the client.

Correct Answer: B

Rationale: Urinary incontinence is a risk factor for developing pressure injuries due to prolonged skin exposure to moisture and irritants. Dehydration (choice A) can contribute to skin dryness but is not a direct risk factor for pressure injuries. Poor nutrition (choice C) can affect wound healing but is not specifically linked to pressure injuries. Poor tissue perfusion (choice D) can increase the risk of tissue damage but is not as directly associated with pressure injuries as urinary incontinence.

Correct Answer: B

Rationale: The correct answer is to assess blood pressure first. Enalapril is an ACE inhibitor commonly used to manage hypertension. It is crucial to evaluate the patient's blood pressure before administering enalapril to ensure it is within safe limits. Assessing other parameters like heart rate, serum creatinine, and potassium levels is also important but assessing blood pressure takes precedence due to the medication's mechanism of action and potential effects on blood pressure regulation.

Correct Answer: C

Rationale: The correct task that the charge nurse should delegate to the LPN is to administer an oral antibiotic to a patient. LPNs are trained and permitted to administer medications orally under the supervision of a registered nurse. Initiating a care plan (Choice A) and completing an initial assessment (Choice D) are tasks that typically require higher-level nursing education and critical thinking skills, which are more suitable for registered nurses. Performing a complex wound dressing change (Choice B) involves specialized skills and assessment that are often within the scope of practice of registered nurses or wound care specialists.
