The nurse does not take shortcuts for example failing to identify a client when administering medications. This is an example of critical thinking attitude:

Correct Answer: A

Rationale: Responsibility and accountability as a critical thinking attitude mean adhering to standards and owning outcomes, like verifying a client's identity before medication to ensure safety. This reflects duty to the patient and profession, avoiding errors (e.g., wrong patient dosing). Thinking independently involves personal judgment, not just following protocol, which this nurse does by sticking to rules. Fairness ensures impartiality, not directly tied to identification steps. Discipline implies consistency, overlapping with responsibility, but lacks accountability's emphasis on answerability. By not cutting corners, the nurse upholds ethical and safety standards, embodying responsibility and accountability, critical for trust and precision in medication administration, a high-stakes nursing task.

Correct Answer: C

Rationale: Upper and Lower GI series use a body system framework (C), targeting digestive system, per assessment types. Functional (A) assesses ADLs, head-to-toe (B) and cephalocaudal (D) are physical sweeps. C fits organ focus, making it correct.

Correct Answer: D

Rationale: Slightly pale yellow is normal e.g., hydrated urine per standards. Dark amber (dehydration), yellow cloudy (infection), light yellow amber (concentrated) differ. Nurses assess e.g., hydration for health, per norms.

Correct Answer: A

Rationale: For developmental dysplasia of the hip (DDH), a body cast (spica) is often applied to maintain hip alignment, a common intervention post-reduction in infants, guided by orthopedics. Prone positioning, early surgery, or spontaneous correction aren't standard treatment stabilizes the joint. Nurses prepare families for this, explaining its role in preventing long-term disability, ensuring compliance and comfort.

Correct Answer: B

Rationale: Chlorine tablets disinfect water by releasing hypochlorous acid to kill pathogens. Standard tablets (e.g., 1 mg chlorine) are designed to treat specific volumes based on concentration needs (typically 0.5-2 mg/L). Choice A (10 L) underestimates common tablet capacity, while C (30 L) and D (40 L) exceed typical single-tablet efficacy without specifying tablet strength. B (20 L) aligns with widely used chlorine tablets (e.g., NaDCC) for household water purification, achieving safe levels per WHO guidelines. Nurses educating communities on water safety must clarify dosage, ensuring effective pathogen control without overdose, making 20 L the correct, practical answer.

Correct Answer: A

Rationale: Kardex (A) is a concise, card-based system for shift reports, per nursing practice. Progress notes (B) detail chronologically, SOAPIE (C) structures per problem, shift reports (D) are verbal. A fits the portable file description, making it correct.

Correct Answer: D

Rationale: Preventing complications of hypoxia (D) is the primary indication for oxygen therapy in COPD with severe dyspnea and hypoxemia, averting tissue damage and organ failure (target SpO2 88-92%). Saturation above 95% (A) risks CO2 retention in COPD. Correcting pathology (B) requires other treatments. Relieving dyspnea (C) is a benefit, not the goal. Hypoxia prevention aligns with GOLD guidelines, prioritizing survival and function over symptom relief alone.

Correct Answer: C

Rationale: Tertiary care is highly specialized (C), per system e.g., surgery, rehab. Not by GPs (A), not promotion (B), not all (D) advanced focus. C truly defines tertiary's complexity, making it correct.

Correct Answer: C

Rationale: Measuring girth at the most distended level and charting it confirms abdominal distention objectively, critical for tracking. Verification, umbilicus measurement, or client query are less precise. Nurses rely on this for accurate monitoring.
