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.
Which of the following findings is associated with right-sided heart failure?
- A. Shortness of breath
- B. Nocturnal polyuria
- C. Daytime oliguria
- D. Crackles in the lungs
Correct Answer: B
Rationale: Nocturnal polyuria is linked to right-sided heart failure, where fluid shifts from edematous tissues to the bloodstream at night, increasing urine output as the heart struggles to pump against venous congestion. Shortness of breath and crackles typify left-sided failure, while daytime oliguria isn't specific. Nurses monitor this to assess heart function, guiding fluid management and diuretic use effectively.
A client with chronic obstructive pulmonary disease (COPD) presents with severe dyspnea and hypoxemia. What is the appropriate indication for initiating oxygen therapy in this client?
- A. Maintaining oxygen saturation above 95%
- B. Correcting underlying lung pathology
- C. Relieving shortness of breath
- D. Preventing complications of hypoxia
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.

- A. Health care financing

One of your assigned clients gets up to go to the bathroom without calling you. The client falls to the floor and calls for help. You answer the call and alert your supervisor. After assuring that the vital signs are normal and there does not appear to be any injuries, you are told to fill out an incident report. In addition to noting that the client was found on the floor, which of the following statements would you most need to record in the nursing notes for the client?
- A. Incident report completed.'
- B. the reason the client was unattended
- C. the vital signs and assessment of the client
- D. location of the incident report
Correct Answer: C
Rationale: After a fall, recording vital signs and assessment in nursing notes is most needed, providing a clinical picture post-incident like stable pulse and no fractures for care and legal purposes. Noting the report's completion or location is administrative, and explaining absence justifies but doesn't document health status. This ensures comprehensive client-focused documentation.
