To prepare a presentation on the greatest health concern facing the city, how should the health nurse begin collecting data?

Correct Answer: A

Rationale: The correct answer is to review morbidity data for the city's population compiled by the Bureau of Vital Statistics. Morbidity data provides detailed and accurate information on the health issues prevalent in the city's population. This data is essential as it reflects actual health conditions rather than perceptions or specific hospital data. Conducting a telephone survey (choice B) may provide subjective opinions rather than objective data. Surveying hospitals (choice C) may only capture data on hospitalized cases and may not represent the entire population. Contacting American Medical Association members (choice D) may provide insights into medical treatments but may not reflect the overall health concerns of the city's population.

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: 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: B

Rationale: Inviting individuals in recovery to share their stories is the most effective strategy for educating adolescents about the dangers of substance abuse. Personal stories have a significant impact as they provide real-life examples of the consequences of substance abuse, making the information more relatable and emotionally engaging. This approach can evoke empathy, create a deeper understanding of the risks involved, and potentially deter adolescents from experimenting with substances. Showing videos of the effects of substance abuse (choice A) may be impactful, but personal narratives often have a stronger emotional connection. Providing statistical data (choice C) may not resonate as strongly with adolescents as personal stories. Distributing brochures (choice D) is informative but may not have the same emotional impact and engagement as hearing firsthand experiences.

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.

Correct Answer: C

Rationale: The correct answer is C. Sudden severe abdominal pain is a key clinical manifestation of a perforated ulcer. The sudden onset of severe pain is concerning for a perforation in the ulcer, which can lead to peritonitis if not promptly addressed. Choices A, B, and D are incorrect because hyperactive bowel sounds, a soft and nondistended abdomen, and a blood pressure of 110/70 mm Hg are not specific indicators of a perforated ulcer. Hyperactive bowel sounds may suggest increased gastrointestinal motility, a soft abdomen may not necessarily indicate a perforation, and a blood pressure of 110/70 mm Hg is within normal limits and does not directly relate to a perforated ulcer.

Correct Answer: A

Rationale: A serum calcium level of 11 mg/dL indicates hypercalcemia, which can be a complication of hyperparathyroidism and requires immediate intervention. Hypercalcemia can lead to serious complications such as cardiac dysrhythmias, renal failure, and neurologic symptoms. Monitoring and managing serum calcium levels are crucial in clients with hyperparathyroidism. Serum phosphorus, magnesium, and albumin levels are important to assess in clients with hyperparathyroidism, but they do not require immediate intervention as hypercalcemia poses a more urgent risk.

Correct Answer: D

Rationale: Decreased deep tendon reflexes are a critical finding in hypokalemia that indicates severe potassium deficiency affecting neuromuscular function. Immediate intervention is necessary to prevent life-threatening complications such as respiratory failure or cardiac arrhythmias. Muscle weakness, irregular heart rate, and increased urinary output are also associated with hypokalemia but do not pose the same level of urgency as decreased deep tendon reflexes.

Correct Answer: C

Rationale: In a client with COPD receiving oxygen therapy, an effective response is indicated by a respiratory rate of 20 breaths per minute. This suggests that the client is effectively oxygenating while maintaining an appropriate respiratory rate. Choices A, B, and D are incorrect because expectorating secretions easily, having an oxygen saturation of 92%, and arterial blood gases showing a pH of 7.35 are not specific indicators of the effectiveness of oxygen therapy in COPD. Oxygen saturation of 92% may still be suboptimal in COPD, and arterial blood gases showing a pH of 7.35 may not necessarily reflect the overall effectiveness of oxygen therapy.
