Nursing Elites

1. In which of the following organs does the exchange of gases take place?

• A. Kidneys
• B. Lungs
• C. Liver
• D. Heart

Correct answer: B

Rationale: The exchange of gases, specifically oxygen and carbon dioxide, occurs in the lungs. In the lungs, oxygen from the air we breathe enters the bloodstream, while carbon dioxide is removed from the bloodstream and exhaled. This process is essential for respiration and supplying the body with oxygen for energy production. The kidneys filter waste from the blood to produce urine and regulate fluid balance (Choice A). The liver is involved in detoxification, protein synthesis, and producing bile (Choice C). The heart is responsible for pumping blood throughout the body to deliver oxygen and nutrients (Choice D).

2. Parenteral penicillin can be administered as an:

• A. IM injection or an IV solution
• B. IV or an intradermal injection
• C. Intradermal or subcutaneous injection
• D. IM or a subcutaneous injection

Correct answer: A

Rationale: Penicillin can be administered intramuscularly or intravenously.

3. Which deficiency is most commonly seen in individuals with alcohol use disorder?

• A. Thiamine
• B. Riboflavin
• C. Pyridoxine
• D. Pantothenic acid

Correct answer: A

Rationale: Thiamine deficiency, also known as Vitamin B1 deficiency, is the most common vitamin deficiency seen in individuals with alcohol use disorder. Chronic alcohol consumption can lead to decreased thiamine absorption and utilization, as well as poor dietary intake. Thiamine deficiency can result in serious neurological complications, such as Wernicke-Korsakoff syndrome, making it essential to address thiamine supplementation in individuals with alcohol use disorder.

4. The healthcare provider orders an IV solution of dextrose 5% in water at 100ml/hour. What would the flow rate be if the drop factor is 15 gtt = 1 ml?

• A. 5 gtt/minute
• B. 13 gtt/minute
• C. 25 gtt/minute
• D. 50 gtt/minute

Correct answer: C

Rationale: To determine the flow rate in drops per minute, multiply the ordered volume per hour by the drop factor (100 ml/hour x 15 gtt/ml = 1500 gtt/hour). Then, divide the result by 60 minutes to convert it to drops per minute (1500 gtt/hour ÷ 60 minutes = 25 gtt/minute). Therefore, the correct answer is 25 gtt/minute.

5. What is a nurse's role in health promotion?

• A. Conducting health risk appraisals
• B. Educating clients to be effective health consumers
• C. Implementing worksite wellness programs
• D. None of the above

Correct answer: B

Rationale: A nurse plays a crucial role in health promotion by educating clients to be effective health consumers. This involves empowering individuals to make informed decisions about their health, access appropriate healthcare services, and engage in healthy behaviors to prevent illness and promote well-being. The other choices are not entirely accurate in describing the primary role of a nurse in health promotion. While nurses may conduct health risk appraisals and implement worksite wellness programs as part of their responsibilities, their central focus is on educating and empowering individuals to take control of their health.
