Correct Answer: A

Rationale: The patient's pH is below the normal range (7.35-7.45), and the HCO3 is also below the normal range (22-26 mEq/L), indicating an acidic environment, which is consistent with metabolic acidosis. The ABGs provided do not support respiratory acidosis or alkalosis, as the PaCO2 is within the normal range (35-45 mm Hg) despite the patient's deep, rapid respirations. Therefore, the correct interpretation is metabolic acidosis.

Correct Answer: B

Rationale: In this situation, where there is a conflict between the client's significant other and estranged husband, the most appropriate intervention is to request a consultation with the ethics committee for resolution. This ensures that an impartial body can assess the situation, consider the rights and preferences of all parties involved, and provide guidance on how to proceed in a fair and ethical manner. Obtaining a court order (Choice A) may be a legal option but should be considered after exhausting other conflict resolution methods. Involving security (Choice C) may escalate the situation and should only be considered if there is a risk of harm. Discussing boundaries with the client (Choice D) is important but may not immediately address the current conflict between the significant other and the husband.

Correct Answer: B

Rationale: Daily weight is the most easily obtained and accurate means of assessing volume status. Skin turgor varies considerably with age and can be affected by various factors other than fluid balance. Presence of edema indicates excess fluid has moved into the interstitial space, which may not always be directly correlated with overall fluid balance. Hourly urine outputs, though important, do not provide a comprehensive picture of fluid balance as they do not consider fluid intake, insensible losses, or other sources of fluid loss.

Correct Answer: A

Rationale: The client has a plan to read until feeling sleepy, indicating an intention to sleep. Therefore, offering a PRN sedative-hypnotic (C) is unnecessary, especially since it is a stronger sleep aid. Option (D) is not needed as the client already has a plan to address his sleeplessness. Assessing the surgical dressing (B) is not relevant to the client's immediate need for sleep. Leaving the room and closing the door (A) is the appropriate action to provide a conducive environment for the client to rest.

Correct Answer: B

Rationale: An experienced LPN/LVN can monitor IV sites for signs of infection because it falls within their education, experience, and scope of practice. Administering IV antibiotics through an implantable port, adjusting infusion rates, and removing central catheters are tasks that require RN level education and scope of practice. These activities involve a higher level of assessment, critical thinking, and potential complications that are typically within the RN's domain.
