One tablet of chlorine is efficient to chlorinate how many litres of water?
- A. 10 Litres
- B. 20 Litres
- C. 30 Litres
- D. 40 Litres
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.

A client attached to mechanical ventilation suddenly becomes restless and pulls out the tracheostomy tube. Which is the nurse's priority intervention?
- A. Prepare for reintubation.
- B. Call the health care provider.
- C. Call the rapid response team.
- D. Check the client for spontaneous breathing.
Correct Answer: D
Rationale: If a tracheostomy tube is dislodged, checking for spontaneous breathing (D) is the priority to assess airway patency and oxygenation need. Preparing for reintubation (A) or calling teams (B, C) follows. D is correct. Rationale: Assessing breathing determines if immediate reinsertion or oxygenation is urgent, guiding next steps per respiratory emergency standards, ensuring patient stability first.
The nurse checked Mr. Gary's dose to prevent an overdose. This is an example of?
- A. Nonmaleficence
- B. Beneficence
- C. Fidelity
- D. Veracity
Correct Answer: A
Rationale: Checking dose to prevent overdose is nonmaleficence (A) avoiding harm, per ethics. Beneficence (B) does good, fidelity (C) keeps promises, veracity (D) tells truth not harm-specific. A fits the nurse's focus on safety, ensuring no adverse effects occur, aligning with nonmaleficence's protective principle, making it correct.
Which of the following statement is NOT true about cultural competence in nursing?
- A. Respects diversity
- B. Improves care
- C. Forces assimilation
- D. Adapts to patient needs
Correct Answer: C
Rationale: Cultural competence respects diversity (A), improves care (B), adapts (D) 'forces assimilation' (C) isn't true, opposes respect, per standards. C's coercion contradicts competence, like with Mr. Gary's beliefs, making it untrue.
Which assessment finding indicates a potential complication of immobility related to the respiratory system?
- A. Increased muscle strength
- B. Increased lung expansion
- C. Diminished breath sounds
- D. Normal respiratory rate
Correct Answer: C
Rationale: Diminished breath sounds signal a respiratory complication from immobility, suggesting poor ventilation or issues like atelectasis or pneumonia due to shallow breathing. Stronger muscles or expanded lungs indicate healthy function, not problems, while a normal breathing rate doesn't reveal underlying lung issues. Nurses auscultate for this to detect early respiratory decline, prompting interventions like repositioning or breathing exercises, ensuring timely action to safeguard oxygenation in immobile patients.
Which standards are monitored by the Quality and Safety Education for Nurses (QSEN)?
- A. Evidence-based practice
- B. Client-centered care
- C. Informatics
- D. Nursing certification
Correct Answer: A
Rationale: The Quality and Safety Education for Nurses (QSEN) initiative defines key competencies to ensure nurses deliver safe, high-quality care, addressing modern healthcare demands. Evidence-based practice integrates the best research with clinical expertise, guiding decisions for effective outcomes. Client-centered care prioritizes individual needs and preferences, balancing advocacy with safety. Informatics leverages technology for accurate documentation and care evaluation, enhancing efficiency. Quality improvement drives ongoing assessment and refinement of practices, while teamwork and collaboration ensure coordinated care delivery. Safety minimizes risks, a core QSEN focus. Nursing certification, though valuable, isn't a QSEN competency, as it's an individual credential, not a universal standard. These standards collectively equip nurses to improve care quality and safety across settings, reflecting a comprehensive approach to professional development and patient well-being.
