Nursing Elites

1. When teaching about electrical fire prevention at a community health fair, which of the following information should be included?

• A. Use three-pronged grounded plugs.
• B. Cover extension cords with a rug.
• C. Check for tingling sensations around the cord to ensure electricity is working.
• D. Remove the plug from the socket by pulling the plug, not the cord.

Correct answer: A

Rationale: The correct answer is to use three-pronged grounded plugs because they are safer and reduce the risk of electrical fires. Option B is incorrect as covering extension cords with a rug can pose a fire hazard. Option C is incorrect; tingling sensations around a cord indicate an electrical issue, not proper functioning. Option D is unsafe; plugs should be removed from the socket by pulling the plug, not the cord, to prevent damage and reduce the risk of electrical hazards.

2. The client was asked to read the Snellen chart. Which of the following is being tested?

• A. Optic
• B. Olfactory
• C. Oculomotor
• D. Trochlear

Correct answer: A

Rationale: The correct answer is A: Optic. The Snellen chart is used to test visual acuity, which assesses the function of the optic nerve responsible for vision. Choices B, C, and D are incorrect. Olfactory relates to the sense of smell, oculomotor controls eye movement, and trochlear controls certain eye muscles. Therefore, the only option related to vision testing in this context is the optic nerve.

3. Which of the following techniques involves the sense of sight?

• A. Inspection
• B. Palpation
• C. Percussion
• D. Auscultation

Correct answer: A

Rationale: The correct answer is Inspection (Choice A). Inspection is a technique that involves observing the patient using the sense of sight. During inspection, a healthcare provider visually examines the patient for any abnormalities, changes, or specific signs that may help in diagnosing a condition. Palpation (Choice B) involves using the sense of touch to feel for abnormalities. Percussion (Choice C) involves tapping the body to produce sounds that can help identify the underlying structures. Auscultation (Choice D) involves listening to sounds produced by the body, typically using a stethoscope. Therefore, in this context, the technique that specifically involves the sense of sight is Inspection.

4. 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).

5. Which of the following white blood cell (WBC) counts clearly indicates leukocytosis?

• A. 4,500/mm³
• B. 7,000/mm³
• C. 10,000/mm³
• D. 25,000/mm³

Correct answer: D

Rationale: Leukocytosis is defined as an increase in the total white blood cell count. A normal WBC count typically ranges from 4,500 to 10,000/mm³. A WBC count of 25,000/mm³, as indicated in choice D, is significantly higher than the normal range and clearly indicates leukocytosis.
