Correct Answer: C

Rationale: The correct answer is C. LPNs are trained to provide basic nursing care such as wound care. Providing wound care for a stage III pressure ulcer falls within the LPN's scope of practice. Administering IV medication (choice A) requires a higher level of skill and is usually the responsibility of registered nurses. Conducting initial client assessments (choice B) demands more advanced training and is typically performed by registered nurses. Teaching a diabetic client about insulin administration (choice D) involves patient education and is usually within the scope of registered nurses or other healthcare professionals with specific training in diabetic care.

Correct Answer: A

Rationale: The correct answer is to notify the anesthesiologist. When a client reports drinking water close to the time of surgery, it is important to inform the anesthesiologist as it can impact the administration of anesthesia. The anesthesiologist needs this information to make decisions regarding anesthesia administration. Documenting the intake in the medical record is important for documentation purposes, but the immediate action needed is to inform the anesthesiologist. Canceling the surgery is not necessary based solely on the intake of water; the anesthesiologist will determine the appropriate course of action. Instructing the client to fast until the surgery may not be appropriate without consulting the anesthesiologist first, as the situation needs to be assessed by the anesthesia team.

Correct Answer: B

Rationale: The correct answer is B. Sodium levels can affect lithium levels in the body, so it is crucial to monitor sodium intake to prevent toxicity or subtherapeutic levels. Lithium is typically taken on an empty stomach to enhance absorption, making choice A more accurate than the original 'Take the medication with food.' Reporting weight gain, as mentioned in choice C, is important for monitoring side effects but is not as critical as ensuring proper lithium levels through sodium intake monitoring. Choice D, avoiding excessive caffeine intake, is not a priority concern directly related to lithium therapy.

Correct Answer: A

Rationale: The correct answer is to advise the client to lie on her side. Lying on the side can prevent the compression of the vena cava, which can cause dizziness in pregnant women. Encouraging the client to drink more fluids (Choice B) may be beneficial for other conditions but is not the best response for dizziness when lying on her back. Suggesting the client elevate her legs when lying down (Choice C) is not directly related to the issue described by the client. Recommending the client take short walks throughout the day (Choice D) may be helpful for other pregnancy-related symptoms but is not the most appropriate action for dizziness when lying on her back.

Correct Answer: D

Rationale: In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This finding indicates impaired liver function affecting the synthesis of clotting factors, leading to an increased risk of bleeding. Elevated AST and ALT levels (Choice A) indicate liver cell damage but do not directly correlate with the risk of bleeding. A decreased albumin level (Choice B) is common in liver disease but is not the most concerning in terms of bleeding risk. Elevated bilirubin levels (Choice C) are seen in liver disease but do not directly reflect the risk of bleeding as PT/INR values do.
