Correct Answer: C

Rationale: The ventrogluteal site is the preferred site for IM injections in adults due to its muscle mass and low risk of nerve injury. The deltoid muscle, although commonly used for vaccines in adults due to easy accessibility, has a smaller muscle mass making it less ideal for IM injections. The vastus lateralis muscle is typically used in infants and young children, not in adults. The dorsogluteal site has a higher risk of injury to the sciatic nerve and is no longer recommended for IM injections in any age group.

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 because social smiling is a developmental milestone typically expected around 2 months of age. At this stage, infants start to engage more with their caregivers and show positive emotional responses. The other choices are incorrect. Choice A describes a motor skill that usually emerges later. Choice C involves more coordination and exploration, which is not typically seen by 2 months. Choice D relates to head control and arm strength, which also develop progressively but may not be fully achieved by 2 months.

Correct Answer: B

Rationale: Restricting protein intake is vital in managing chronic kidney disease (CKD) as it helps decrease the kidneys' workload and slows down disease progression. High-fiber foods are generally beneficial for health and should not be limited in CKD management. Dairy products can be consumed moderately unless contraindicated. While adequate fluid intake is crucial, increasing intake excessively may not be suitable for all CKD patients, especially those with fluid restrictions. Therefore, the most crucial dietary restriction to emphasize in CKD management is restricting protein intake.

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.
