Correct Answer: B

Rationale: The correct answer is the right cephalic vein. The cephalic vein is a large and superficial vein commonly used for IV access. Documenting the specific anatomic name of the vein used for IV access, such as the cephalic vein, is essential for accurate medical records. Option A, the left brachial vein, is incorrect as the brachial vein is too deep to be accessed for IV infusion. Option C, the dorsal side of the right wrist, is not a recommended IV access site due to fragile veins and potential pain for the patient. Option D, right upper extremity, is too broad and lacks the specificity necessary for precise documentation of the IV access site.

Correct Answer: D

Rationale: When administering medications through a nasogastric tube connected to low intermittent suction, the nurse should first turn off the intermittent suction device. This step is crucial to prevent the medications from being immediately suctioned out before they can be absorbed. Clamping the nasogastric tube is not the initial action because it may cause pressure buildup and lead to complications. Confirming the placement of the tube is important but should not be the first step in this scenario. Using a syringe to instill the medications comes after ensuring the suction is turned off to enable proper administration and absorption of the medications.

Correct Answer: B

Rationale: When changing the route of administration from PO to IV, the absorption process is bypassed, leading to a more rapid onset of action of the medication and consequently a quicker effect. Choices A, C, and D are incorrect. Increased drug tolerance and higher doses are not typical outcomes of changing the route of administration. Protein binding does not increase with a change to IV administration; rather, it is the bioavailability and onset of action that are affected. Moreover, an increased therapeutic index reduces the risk of drug toxicity, contrary to what is stated in choice D.

Correct Answer: C

Rationale: The correct document the nurse should use to develop the unit's nursing guidelines for the mental health services department is ANA's Scope and Standards of Nursing Practice. This document specifically outlines the philosophy and standards of nursing practice, including psychiatric nursing. Option A, the Americans with Disabilities Act of 1990, and option D, the Patient's Bill of Rights of 1990, focus on client rights and legal protections rather than nursing practice guidelines. Option B, the ANA Code of Ethics with Interpretive Statements, provides ethical guidelines for nursing practice but does not specifically address the development of nursing guidelines for a mental health services department.

Correct Answer: B

Rationale: When obtaining blood pressure in the lower extremities, the popliteal pulse should be auscultated when the blood pressure cuff is applied around the thigh. The nurse should intervene when the UAP is auscultating the popliteal pulse with the cuff on the lower leg because this is incorrect placement. Option A, wrapping the cuff around the girth of the leg, ensures an accurate assessment. Option C, placing the client in a prone position, provides the best access to the artery. The systolic pressure in the popliteal artery is typically 10 to 40 mm Hg higher than in the brachial artery, so a systolic reading 20 mm Hg higher than the blood pressure in the client's arm is within the expected range and does not require intervention.
