A public health nurse is working with a community to improve vaccination rates. Which intervention is most likely to be effective?

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: 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.

Correct Answer: A

Rationale: Recognizing signs of infant dehydration is crucial for ensuring the health and well-being of infants. Dehydration can be life-threatening for infants if not addressed promptly. Proper diaper changing techniques, while important for hygiene, can be learned incrementally. The immunization schedule and breastfeeding positions are also essential topics, but identifying signs of dehydration takes precedence as it requires immediate attention to prevent serious complications.

Correct Answer: B

Rationale: Prioritizing the topic of how to childproof the home is crucial as it provides a holistic approach to safeguarding children from various injuries within the home environment. Childproofing the home addresses a wide range of hazards such as falls, burns, poisoning, and choking incidents. While topics like the benefits of car seats, the importance of helmet use, and ways to prevent drowning are important, childproofing the home covers a broader spectrum of safety measures that can significantly reduce the risk of injuries for children.
