A client with a history of heart failure is admitted with pulmonary edema. Which finding requires immediate intervention?

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: 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.

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.
