Correct Answer: B

Rationale: The correct answer is B: Furosemide (Lasix). Furosemide is a diuretic that promotes fluid loss, and giving it before hemodialysis can lead to excessive fluid loss during the treatment, potentially causing hypovolemia. Withholding furosemide until after the dialysis session helps in preventing this complication. Choices A, C, and D are incorrect because calcium carbonate, spironolactone, and multivitamins are not typically contraindicated before hemodialysis in clients with chronic renal failure.

Correct Answer: C

Rationale: Peripheral edema in a client with cirrhosis can indicate fluid overload and worsening liver function, necessitating immediate intervention to prevent further complications such as respiratory distress, cardiac issues, or renal impairment. Jaundice (choice A) is a common manifestation of cirrhosis but may not require immediate intervention unless severe. Ascites (choice B) is also a common complication of cirrhosis that may require intervention but is not as urgent as addressing peripheral edema. Spider angiomas (choice D) are typically benign skin lesions associated with cirrhosis but do not require immediate intervention unless bleeding or rupture occurs.

Correct Answer: D

Rationale: The correct answer is D: number of people without access to healthcare. Ensuring access to healthcare is fundamental to addressing a wide range of health issues and is a priority for improving overall community health. Option A, overuse of diagnostic technology, though important, is not the highest priority when considering basic access to healthcare. Option B, government-based health insurance, is relevant but may not directly address the issue of lack of access for all individuals. Option C, neonatal and infant mortality rates, is crucial but addressing access to healthcare for all individuals is a more immediate and foundational concern for the community health project.

Correct Answer: D

Rationale: The prioritized intervention for addressing elder abuse in the community should be the creation of a confidential hotline for reporting abuse. A confidential hotline offers a safe and accessible way for individuals to report elder abuse and seek help promptly. Providing education on the signs of elder abuse (Choice A) is important but may not directly address immediate reporting and intervention needs. Setting up a support group for elder abuse survivors (Choice B) is beneficial for emotional support but may not address the primary need for reporting abuse. Partnering with local law enforcement to increase patrols (Choice C) focuses on prevention rather than providing a direct reporting mechanism for victims.

Correct Answer: C

Rationale: The most appropriate initial action for the community health nurse to take when addressing low immunization rates in a lower socioeconomic area is to review current epidemiological data. By reviewing this data, the nurse can gather evidence that documents the low immunization rate in the community. This information is crucial to support the need for targeted interventions to increase immunization rates. Choices A, B, and D involve actions that may be important at later stages of intervention but are not the first step. Joining a political action group, partnering with a hospital for clinics, or holding a community meeting are all valuable strategies, but they should be based on evidence obtained from reviewing epidemiological data to ensure targeted and effective interventions.
