Correct Answer: A

Rationale: Assisting the client in preparing questions is the most appropriate action as it helps ensure that all concerns are addressed during the provider's visit. By helping the client write down questions, the nurse empowers the client to actively participate in their care and communicate effectively with the provider. Reassuring the client, while well-intentioned, may not address the specific questions or fears the client has. Explaining the procedure in detail may not be what the client is seeking at this moment, as their primary concern is about the provider's actions. Directing the client to search for information online is not recommended as it may lead to confusion or misinformation, and the information may not be tailored to the client's specific situation.

Correct Answer: A

Rationale: Daily weight is the most accurate measure of fluid status in a client with acute renal failure. Fluctuations in weight reflect changes in body fluid volume, including both fluid retention or loss. Intake and output, while important, may not always accurately reflect overall fluid status as it does not account for insensible losses. Urine specific gravity can provide information on urine concentration but does not offer a comprehensive assessment of overall fluid status. Peripheral edema, although a sign of fluid retention, is a more subjective assessment and may not always accurately reflect the client's fluid status like daily weight monitoring does.

Correct Answer: C

Rationale: Inspiratory crackles are a common finding in patients with congestive heart failure due to the accumulation of fluid in the lungs, leading to crackling sounds during inspiration. Chest pain (Choice A) is more commonly associated with conditions like angina or myocardial infarction and is not a typical symptom of congestive heart failure. Pallor (Choice B) is a general symptom of various conditions and not specific to congestive heart failure. While a heart murmur (Choice D) may be heard in some cases of congestive heart failure, it is not as consistent as inspiratory crackles in indicating the condition.

Correct Answer: B

Rationale: The correct answer is B: Maintain alveolar surface tension. Respiratory distress syndrome in premature infants is often caused by a deficiency in surfactant, a substance that helps maintain alveolar surface tension. Without adequate surfactant, the alveoli collapse, making it difficult for the infant to oxygenate effectively. Choices A, C, and D are incorrect because stabilizing alveolar surface tension is not the issue, promoting normal pulmonary blood flow and regulating intra-cardiac pressure are not directly related to the pathophysiology of respiratory distress syndrome in premature infants.

Correct Answer: A

Rationale: An uneven shape of a lesion is a common characteristic of malignant skin lesions. Asymmetric or irregularly shaped lesions are concerning for skin cancer and should be reported promptly for further evaluation and management. Choice B, a uniformly colored lesion, is more indicative of a benign lesion as malignant lesions often exhibit variations in color. Choice C, a lesion that is small and flat, does not necessarily indicate malignancy by itself. Choice D, a lesion that is less than 1 cm in diameter, is more suggestive of a benign lesion, as malignant lesions are typically larger in size.
