Correct Answer: A

Rationale: Before a person becomes violent, observable behaviors may include tense shoulders, clenched fists, a blank stare, and being positioned with one foot in back and an arm pulled back. Wandering is not typically associated with threatening behaviors signaling imminent violence. DelBel (2003) suggests that strategies such as relaxed body language, maintaining physical distance, and silence can help de-escalate an agitated individual's response.

Correct Answer: A

Rationale: Centralization is the most efficient option when utilizing an internal float pool because it allows for a pool of nurses to be used anywhere in the hospital. In centralized pools, staff members are not limited to working for only one nurse manager or on only one unit, unlike in decentralized pools. Flexible and mixed pools may offer some advantages, but in terms of efficiency and utilization of resources, centralized pools are the most effective choice.

Correct Answer: B

Rationale: The correct answer is B. In a young adult with type 1 diabetes, a blood pressure of 146/88 mmHg may indicate the need for a change in therapy as it is above the recommended target levels. High blood pressure can increase the risk of cardiovascular complications in diabetic patients. Choices A, C, and D are within normal ranges and do not necessarily indicate the need for an immediate change in therapy. A Hemoglobin A1C level of 6.2% is generally considered good control for a diabetic patient, a resting heart rate of 58 beats/minute is normal for an active individual, and an HDL level of 65 mg/dL is considered to be in the desirable range for heart health.

Correct Answer: D

Rationale: When assessing the quality of pain, asking if the pain is sharp or dull helps the nurse understand the nature of the pain. Sharp pain is often associated with acute conditions like nerve irritation or injury, while dull pain may indicate a more chronic issue like inflammation or tissue damage. Choices A, B, and C focus on different aspects of pain assessment but do not specifically address the quality of pain, making them less relevant in this context.

Correct Answer: C

Rationale: The correct answer is C because after a lumbar laminectomy, the adolescent may need assistance with personal hygiene due to limited mobility and pain. Encouraging the guardian to assist with personal hygiene ensures proper care and prevents complications. Choice A is incorrect as limiting visitors may affect the adolescent's emotional well-being and support system. Choice B is incorrect as the adolescent should have autonomy in selecting their food choices as long as they align with their dietary restrictions post-surgery. Choice D is incorrect as the adolescent may need guidance and support in decision-making during the postoperative period.
