1. What is the best description of resonance?

• A. Sounds created by air-filled structures
• B. Short, high-pitched, and thudding
• C. Moderately loud with a musical quality
• D. Drum-like

Correct answer: A

Rationale: Resonance refers to the quality of sound produced by vibrations that are reinforced by other vibrations of the same frequency. In the context of the human body, resonance is often associated with sounds produced by air-filled structures like the lungs, vocal cords, and resonating cavities. Therefore, the best description of resonance from the given options is 'Sounds created by air-filled structures.' This choice aligns with the concept of resonance as it relates to sound production in the human body. Choices B, C, and D are incorrect as they do not specifically relate to the concept of resonance or its association with air-filled structures.

2. What is the term for the body's ability to defend itself against specific invading agents such as bacteria, toxins, viruses, and foreign bodies?

• A. Hormones
• B. Secretion
• C. Immunity
• D. Glands

Correct answer: C

Rationale: The correct answer is C: Immunity. Immunity refers to the body's ability to protect itself against specific invading agents like bacteria, toxins, viruses, and foreign bodies by recognizing and destroying them. It is a crucial defense mechanism that helps maintain health and prevent infections and diseases. Choices A, B, and D are incorrect because hormones are chemical messengers, secretion is the process of releasing substances, and glands are organs that produce and release substances, none of which specifically relate to the body's defense against invading agents.

3. A client is scheduled for a thoracentesis. Which of the following supplies should NOT be in the client's room?

• A. Oxygen equipment
• B. Incentive spirometer
• C. Pulse oximeter
• D. Sterile dressing

Correct answer: B

Rationale: During a thoracentesis procedure, the focus is on draining fluid or air from the pleural space. An incentive spirometer, which helps improve lung function, is not a necessary supply for this specific procedure. Oxygen equipment, pulse oximeter for monitoring oxygen saturation levels, and sterile dressing for wound care may be needed during or after the procedure.

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. A client in labor is receiving oxytocin. Which of the following findings indicates that the nurse should increase the rate of infusion?

• A. Urine output of 20 ml/hr.
• B. Montevideo units constantly at 300 mm Hg.
• C. FHR pattern showing absent variability.
• D. Contractions occurring every 5 minutes and lasting 30 seconds.

Correct answer: B

Rationale: Montevideo units measure the strength and frequency of contractions during labor. A consistent Montevideo units reading of 300 mm Hg or higher is indicative of effective uterine contractions. In this scenario, an increase in the rate of oxytocin infusion may be warranted to further augment contractions and promote progress in labor. The other options, such as low urine output, absent variability in fetal heart rate, and short contractions, do not directly correlate with the need for an increase in oxytocin infusion rate.
