A public health nurse is working with a community to improve access to healthcare services. Which intervention is most likely to be effective?

Correct Answer: A

Rationale: Setting up mobile clinics in underserved areas is the most effective intervention to improve access to healthcare services. Mobile clinics directly bring healthcare services to the community, making it convenient for residents to access care without having to travel long distances. Distributing flyers may increase awareness but may not address the barriers to access. Offering transportation vouchers helps with one aspect of access but does not directly provide healthcare services. Partnering with local businesses for discounts may not address the primary issue of physical access to healthcare services in underserved areas.

Correct Answer: A

Rationale: Setting up vaccination clinics in accessible locations is the most effective intervention to improve vaccination rates. This intervention ensures easy access to vaccination services for community members, removing barriers such as transportation or time constraints. Distributing flyers (Choice B) may increase awareness but may not directly address access issues. Offering incentives (Choice C) might temporarily boost vaccination rates but may not lead to sustained behavior change. Partnering with local businesses (Choice D) could be beneficial for promotion but may not directly impact vaccination accessibility.

Correct Answer: D

Rationale: A productive cough with pink, frothy sputum is a classic sign of pulmonary edema, indicating fluid in the lungs. This finding requires immediate intervention to prevent respiratory compromise and worsening of the condition. Peripheral edema (Choice A) is a manifestation of heart failure but is not as urgent as addressing pulmonary edema. Oxygen saturation of 88% (Choice B) is low and requires attention, but the pink, frothy sputum signifies acute respiratory distress. Jugular vein distention (Choice C) can be seen in heart failure, but the immediate concern in this scenario is addressing the pulmonary edema to ensure adequate gas exchange and oxygenation.

Correct Answer: D

Rationale: Weight loss of 5 pounds in one week in a client with hyperthyroidism is concerning as it may indicate severe hypermetabolism, leading to potential complications such as cardiac arrhythmias, muscle weakness, and other metabolic disturbances. Rapid weight loss in hyperthyroidism indicates an accelerated metabolic rate and increased energy expenditure, which can be detrimental to the client's health. The other assessment findings (heart rate of 100 beats per minute, blood pressure of 150/90 mm Hg, respiratory rate of 24 breaths per minute) are commonly seen in clients with hyperthyroidism and may not necessarily require immediate intervention unless they are significantly outside the normal range or causing distress to the client.

Correct Answer: D

Rationale: The correct answer is D: Serum sodium of 130 mEq/L. In SIADH, there is excess release of antidiuretic hormone leading to water retention and dilutional hyponatremia. A serum sodium level of 130 mEq/L indicates severe hyponatremia, which can result in neurological symptoms, such as confusion, seizures, and coma. Therefore, immediate intervention is required to prevent further complications. Choice A, a serum sodium of 140 mEq/L, is within the normal range and does not require immediate intervention. Choice B, serum potassium of 4.5 mEq/L, is also within the normal range and is not directly related to SIADH. Choice C, serum osmolality of 280 mOsm/kg, is a measure of the concentration of solutes in the blood and may not be the most critical parameter to address in a client with SIADH and severe hyponatremia.
