Nursing Elites

1. Which natural body defense plays an active role in preventing infection?

• A. Yawning
• B. Body hair
• C. Hiccupping
• D. Rapid eye movements

Correct answer: B

Rationale: Body hair plays an active role in preventing infection by acting as a filter to block pathogens. It helps to prevent harmful substances from entering the body through the skin, providing a physical barrier against potential infections.

2. A client is being instructed on how to perform pursed-lip breathing. Which of the following should be included in the plan of care?

• A. Take quick breaths upon inhalation.
• B. Place your hand over your stomach.
• C. Take a deep breath in through your nose.
• D. Puff your cheeks upon exhalation.

Correct answer: C

Rationale: Pursed-lip breathing is a breathing technique that involves inhaling slowly through the nose and exhaling gently through pursed lips. This technique helps improve breathing efficiency and can be beneficial for individuals with respiratory conditions. Instructing the client to take a deep breath in through the nose is essential for proper execution of pursed-lip breathing, making choice C the correct answer.

3. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:

• A. Infection
• B. Hypothermia
• C. Anxiety
• D. Dehydration

Correct answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

4. 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.

5. A nurse obtained a client’s pulse and found the rate to be above normal. The nurse documents this finding as:

• A. Tachypnea
• B. Hyperpyrexia
• C. Arrhythmia
• D. Tachycardia

Correct answer: D

Rationale: When a nurse finds a client's pulse rate to be above normal, it is documented as tachycardia. Tachycardia specifically refers to an elevated heart rate, while tachypnea is rapid breathing, hyperpyrexia is high fever, and arrhythmia is an irregular heartbeat. Therefore, the correct term to describe an above-normal pulse rate is tachycardia.
