Correct Answer: A

Rationale: The legal right to confidentiality of client information is waived when a court system subpoenas information. This occurs when information is required for legal proceedings to occur, such as through summonses, court orders, or litigation information necessary for the court. Subpoenas are legal orders that compel the disclosure of information. The other choices do not inherently waive the legal right to confidentiality. A family member's request for health care information would typically require the client's consent or fall under specific legal exceptions. A living will dictates end-of-life care preferences but does not necessarily waive confidentiality. Lastly, the declaration of incompetence may impact decision-making capacity but does not automatically waive confidentiality.

Correct Answer: A

Rationale: The correct action for a client with major head trauma receiving bolus enteral feeding is to measure intake and output (I&O). Enteral feedings are hyperosmotic agents that can cause fluid shifts. Monitoring I&O is crucial to assess fluid balance, ensuring that input matches output. Checking albumin levels (choice B) is important for assessing nutritional status but is not the immediate priority in this situation. Monitoring glucose levels (choice C) is also important but not as critical as measuring I&O in this context. Increasing enteral feeding (choice D) should only be done based on a healthcare provider's order after assessing the patient's condition, not as the most important nursing order at this time.

Correct Answer: D

Rationale: The nurse should stand about 6 feet from the source of the fire. Getting closer might put the nurse in danger. Choice A, 1 foot, is incorrect because it is too close to the fire and can expose the nurse to unnecessary risk. Choice B, 2 feet, is also too close to the fire and may lead to potential harm. Similarly, choice C, 4 feet, is not the ideal distance as it is still within the range of potential danger. The correct answer is D, 6 feet, which is a safe distance for the nurse to extinguish the fire effectively without risking personal safety.

Correct Answer: B

Rationale: Ten seconds is the usual amount of time the nurse should spend for each suction pass. Two seconds is not enough time to effectively remove secretions, while 20 and 30 seconds are too long and could lead to hypoxia and tissue trauma. Therefore, the correct choice is 10 seconds, as it strikes a balance between removing secretions adequately and minimizing the risks associated with prolonged suctioning.

Correct Answer: D

Rationale: Before administering any medication, including IV Vancomycin, it is crucial to ensure that the client is not allergic to the medication. This is the most critical action to prevent any potential allergic reactions. While performing a physical assessment is important, it may not be as time-sensitive as checking for allergies. Obtaining lab values related to renal function is also significant with Vancomycin due to its potential nephrotoxicity, but ensuring the client's safety by checking for allergies takes precedence. Reviewing peaks and troughs is important for monitoring drug levels, but it is a secondary step compared to checking for allergies prior to administration.
