1. What happens to the speed of a sound wave when it travels from air to water?

• A. It increases because water is denser.
• B. It decreases because water is denser.
• C. It remains the same.
• D. Speed depends on the frequency, not the medium.

Correct answer: A

Rationale: Sound waves travel faster in denser mediums like water compared to air due to stronger interactions between particles.

2. Antidiuretic hormone (ADH) helps the kidneys regulate:

• A. Acid-base balance
• B. Blood pressure
• C. Urine output by controlling water reabsorption
• D. All of the above

Correct answer: C

Rationale: The correct answer is C: 'Urine output by controlling water reabsorption.' Antidiuretic hormone (ADH) is released by the pituitary gland and acts on the kidneys to regulate water reabsorption. When ADH levels are high, the kidneys reabsorb more water, leading to concentrated urine and decreased urine output. This helps maintain the body's water balance and prevent dehydration. While ADH indirectly influences blood pressure by regulating blood volume, its primary function is to control water balance, not acid-base balance. Therefore, the correct answer is C.

3. Which property of a wave represents the distance between two successive identical points on a wave?

• A. Wavelength
• B. Amplitude
• C. Frequency
• D. Period

Correct answer: a

Rationale: Wavelength is the distance between two identical points (like crests or troughs) on a wave.

4. Which pattern of nursing care involves the care given by a group of paraprofessional workers

• A. Case method
• B. Modular nursing
• C. Nursing case management
• D. Team nursing

Correct answer: A

Rationale: The correct answer is A: 'Case method.' The case method of nursing care involves the care provided by a group of paraprofessional workers, such as nursing assistants or aides, under the supervision of professional nurses. In this model, the nursing team works together to deliver care to a group of patients based on their specific needs and conditions. This method allows for efficient and coordinated care delivery, with each member of the team playing a crucial role in meeting the patients' healthcare needs. It is important for nurses to effectively delegate tasks and supervise paraprofessional workers in the case method model to ensure high-quality care and patient safety.

5. Cartilage, a type of connective tissue, provides flexible support in various structures. Which of these does NOT contain cartilage?

• A. Ears
• B. Joints
• C. Muscles
• D. Nose

Correct answer: C

Rationale: Muscles do not contain cartilage. Cartilage is a specialized type of connective tissue that provides flexible support in structures like the ears, joints, and nose. Ears have cartilage in their structure, which helps maintain their shape and flexibility. Joints, such as the knee and elbow, have cartilage to cushion and reduce friction between bones. The nose also contains cartilage, forming its shape and structure. Muscles, on the other hand, are made up of muscle tissue and do not contain cartilage. Therefore, muscles are the correct answer as they do not contain cartilage, unlike the other options.

6. Identify the noun clause in the sentence: "My biggest fear is that I wouldn't live life to the fullest."

• A. "My biggest fear"
• B. "that I wouldn't live life to the fullest"
• C. "life"
• D. "the fullest"

Correct answer: B

Rationale: Option B functions as the object of the verb "is," making it a noun clause.
