A newly admitted client has taken thioridazine (Mellaril) for 2 years with good symptom control. Symptoms exhibited on admission included paranoid delusions and hallucinations. The nurse should recognize which potential cause for the return of these symptoms?

Correct Answer: C

Rationale: Rationale: Choice C is correct because not taking the medication as prescribed can lead to a return of symptoms. Missing doses or not taking it at the right time can result in a decrease in the drug's effectiveness. This can cause a relapse of symptoms like paranoid delusions and hallucinations. Incorrect Choices: A: Tolerance to the medication is unlikely after only 2 years of use. B: Taking the medication without food may affect absorption but is less likely to directly cause a return of symptoms. D: Combining alcohol with the medication can have adverse effects, but it is not the most likely reason for the return of symptoms in this case.

Correct Answer: B

Rationale: The correct answer is B: Advanced care directive. This document allows individuals to outline their healthcare preferences in the event they are unable to communicate. It provides clear instructions on the type of care they wish to receive or refuse. Verbal consent (A) is temporary and may not accurately reflect long-term preferences. Durable power of attorney (C) designates a person to make healthcare decisions, but may not include specific preferences. Comfort measures only (CMO) order (D) is a medical directive for end-of-life care, not a comprehensive document like an advanced care directive.

Correct Answer: B

Rationale: The correct answer is B, the staff RN with 3 years of experience who enjoys orienting new employees. This choice is the best because of the staff RN's combination of experience and willingness to mentor. The 3 years of experience indicate a good foundation of knowledge and skills, making them a suitable preceptor for the new graduate. Additionally, their enjoyment of orienting new employees suggests they have a positive attitude towards teaching and mentoring, which is crucial for a successful preceptor-preceptee relationship. A: The charge RN may be a natural leader and know policies, but that doesn't necessarily translate to being the best preceptor for a new graduate who needs guidance and support in clinical practice. C: The LPN may have extensive experience and knowledge of doctor's preferences, but the scope of practice and educational background differ from that of an RN, making them less suitable for preceptorship. D: The staff RN with 10 years of experience refusing to work with students is not an ideal

Correct Answer: B

Rationale: The correct answer is B: homeostasis. Homeostasis refers to the body's ability to regulate internal conditions to maintain stability and balance. It involves various physiologic mechanisms such as temperature regulation, blood pressure control, and pH balance. Homeostasis is crucial for the body to function properly. A: Stress is a state of mental or emotional strain and is not the same as the body's internal balance regulation. C: Self-regulation is a broad term that can encompass various aspects of personal control and behavior, but it does not specifically refer to the body's physiological balance. D: Fight-or-flight response is a specific physiological response to perceived threats, not the overall process of maintaining internal balance.

Correct Answer: B

Rationale: The correct answer is B: Presbyopia. Presbyopia is a common age-related condition where the eye's lens loses flexibility, leading to difficulty focusing on close objects. Myopia (choice A), nearsightedness, is not specifically associated with aging. Strabismus (choice C), misalignment of the eyes, typically develops in childhood. Astigmatism (choice D), an irregular curvature of the eye's cornea or lens, can affect people of all ages, not just older adults. Presbyopia is the most relevant choice for visual changes associated with aging due to the natural aging process affecting the eye's ability to focus on close objects.
