Correct Answer: D

Rationale: The correct answer is D: "Red streaks tracking the vein." Red streaks indicate phlebitis, an inflammation of the vein that can lead to serious complications like infection or thrombophlebitis. Immediate intervention is required to prevent further damage. Choice A, cool skin at the IV insertion site, could indicate decreased circulation but is not as urgent as addressing phlebitis. Choice B, presence of fluid leaking around the IV catheter, may indicate infiltration or dislodgement of the catheter, requiring intervention but not as urgently as phlebitis. Choice C, swelling above the IV site, may suggest localized inflammation but doesn't pose an immediate threat like phlebitis does.

Correct Answer: B

Rationale: The correct answer is B. The client has a legal right to be informed about their treatment, including medication uses and side effects, as part of informed consent. This helps ensure that the client can make an informed decision about their care. Choice A is incorrect because the nurse can provide the client with information about their medications. Choice C is incorrect as it is not an independent decision of the nurse but a professional responsibility to educate clients. Choice D is incorrect as knowledge about medication side effects can actually empower clients to manage their condition effectively.

Correct Answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

Correct Answer: D

Rationale: The nurse's legal responsibility is to ensure that informed consent has been obtained by verifying that the client has signed the form and that it is included in the record. Witnessing the consent and signing as a witness is not the nurse's role, as this is typically done by a neutral party. Informing the client of alternatives to the procedure and explaining the procedure in detail are responsibilities of the healthcare provider performing the surgery, not the nurse.

Correct Answer: B

Rationale: In pancreatitis, pain after consuming fatty foods is common due to increased pancreatic stimulation. Administering antispasmodics is the appropriate intervention as it can help reduce the pain by decreasing pancreatic enzyme secretion. Encouraging the client to eat small, low-fat meals (Choice A) is beneficial in managing pancreatitis symptoms but does not directly address the acute pain. Instructing the client to avoid eating until the pain subsides (Choice C) may lead to nutritional deficiencies and is not the best approach. Increasing high-protein foods intake (Choice D) is not recommended as it can put additional strain on the pancreas.
