Correct Answer: C

Rationale: A major depressive episode with psychotic features is considered a psychiatric emergency because it poses a significant risk to the individual's safety. Psychotic features in depression can include hallucinations, delusions, or other severe symptoms that require immediate intervention. While Seasonal Affective Disorder (SAD) and depression with melancholic features are serious conditions, they do not inherently represent an acute emergency that necessitates immediate hospitalization. Bipolar depression, although severe, does not inherently involve psychotic symptoms that would classify it as a psychiatric emergency requiring immediate intervention. It's crucial to recognize the urgency and severity of major depressive episodes with psychotic features to ensure appropriate and timely treatment.

Correct Answer: D

Rationale: The client stating, 'This is a new pill I have never taken before,' is the correct answer as it indicates a potential discrepancy in the medication order. This statement requires further assessment to ensure the medication is correct, verify if it is a new prescription or a different manufacturer, and determine if the client needs additional instructions. While the timing of medication administration (option A) is important, it may not be as critical as ensuring the accuracy of the medication being administered. Option B, regarding the cost of pills, is relevant for discharge planning but does not directly impact the immediate administration of the medication. Option C, expressing tiredness from taking pills daily, may warrant discussion on adherence or side effects but does not raise immediate concerns about the specific medication being administered.

Correct Answer: B

Rationale: To calculate the volume to administer, use the formula: (Volume to administer = (Ordered Dose × Volume on hand) / Dose on hand). In this case, it would be (4 mg × 1 mL) / 5 mg = 0.8 mL. Therefore, the nurse should administer 0.8 mL of diazepam. Choice A (0.2 mL) is incorrect because it miscalculates the dosage. Choice C (1.25 mL) and Choice D (2.0 mL) are incorrect as they do not align with the correct calculation based on the ordered dose and available concentration. The correct answer, 0.8 mL, is derived from accurate dosage calculation and aligns with the formula for IV medication administration, ensuring the safe and effective delivery of the medication to the client.

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: 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.
