Rationale: A heavy hemostat is used to attach or detach a scalpel blade safely from its handle.

Correct Answer: B

Rationale: Therapeutic touch reduces anxiety in anxious elderly patients non-pharmacologically, per holistic care. Analgesia , pre-op meds , or sleeping pills may help but should follow non-drug attempts first. Preoperative support prioritizes comfort.

Correct Answer: C

Rationale: The American Nurses Association (ANA) defines health as a dynamic state influenced by multiple factors, with a particular emphasis on environment and health status. 'Environment and Health status,' is correct because it reflects the ANA's holistic view, recognizing that health is shaped by one's surroundings (physical, social, and cultural) and current well-being, rather than just biological factors. 'Health and Wealth,' is incorrect, as wealth is not a core component of the ANA's definition, though it may indirectly influence health. 'Behaviour and development,' focuses on individual actions and growth, which are aspects of health but not the primary duo highlighted by the ANA. 'Economics and Environment,' includes environment but substitutes economics for health status, missing the ANA's focus on the individual's condition. The ANA's framework, rooted in nursing's patient-centered approach, prioritizes how environment interacts with health status to define well-being, making C the accurate choice based on its established standards.

Correct Answer: A

Rationale: Indicator strips confirm that sterilization conditions (e.g., temperature, pressure) were met for sterility.

Correct Answer: D

Rationale: Ketamine HCl causes dissociative reactions and nausea , increases heart rate (not lowers BP, choice B), and is short-acting . It minimally depresses respiration . The rationale clarifies pharmacology: ketamine's dissociative state (hallucinations) and emetic effects are notable; it stimulates cardiovascularly, aiding unstable patients, and wears off quickly. Nursing manages these (e.g., antiemetics), leveraging its benefits, distinct from respiratory-depressing agents.

Correct Answer: A

Rationale: The nurse's best first action is notifying the surgeon because shellfish allergy may indicate iodine sensitivity, critical for surgical antiseptics or contrast dyes. Developing a safety plan follows notification. A shellfish-free diet is irrelevant preoperatively, and family history is secondary. The rationale prioritizes communication: the surgeon must adjust protocols (e.g., alternative antiseptics) to prevent anaphylaxis, a life-threatening risk. Nursing's role is to escalate allergies immediately, ensuring the surgical team adapts, aligning with safety standards and preventing adverse reactions during the procedure.

Correct Answer: D

Rationale: Choice D as a PTT of 98 sec indicates bleeding risk, requiring immediate heparin adjustment. Fever (choice A), normal breathing (choice B), and voiding (choice C) are less urgent. This prioritizes safe care per NCLEX, managing anticoagulation in progressive care.

Correct Answer: B

Rationale: It is a body of State law' as it defines RN scope state-by-state unlike 'activity list' (A), 'federal law' (C), or 'public health' (D). In nursing, legal scope guides practice; B aligns with NCLEX Perioperative, clarifying regulatory framework.

Correct Answer: B

Rationale: Maintaining airway prevents hypoxemia, per immediate post-op priorities. Hemorrhage , pain , and vitals follow. PACU care starts with breathing.
