1. Which vitamin requires the lymphatic system for proper absorption from the intestine?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin B12

Correct answer: D

Rationale: The correct answer is D, Vitamin B12. Vitamin B12 requires the presence of intrinsic factor, a protein produced by the stomach, for absorption in the small intestine. This complex is then absorbed in the ileum with the help of the intrinsic factor. The absorption of Vitamin B12 is a unique process that relies on the function of the lymphatic system to transport it throughout the body. Vitamins A, C, and D are absorbed through other mechanisms and do not require the lymphatic system for proper absorption.

2. A birthday party hat has a cone-shaped top with a radius of 5cm and a height of 12cm. What is its volume?

• A. 60 cu cm
• B. 120 cu cm
• C. 150 cu cm
• D. 180 cu cm

Correct answer: C

Rationale: Use the formula for volume of a cone: (1/3) * π * (radius)^2 * height. Substitute the values: (1/3) * π * (5cm)^2 * 12cm ≈ 150 cu cm.

3. What is the medical term for heartburn, a burning sensation in the chest caused by stomach acid?

• A. Dysphagia
• B. Gastroesophageal reflux disease (GERD)
• C. Peptic ulcer
• D. Ulcerative colitis

Correct answer: B

Rationale: Rationale: A) Dysphagia refers to difficulty swallowing and is not specifically related to heartburn. B) Gastroesophageal reflux disease (GERD) is the medical term for heartburn, which is a burning sensation in the chest caused by stomach acid flowing back up into the esophagus. C) Peptic ulcer is a sore that develops on the lining of the stomach, small intestine, or esophagus, and it can cause symptoms such as abdominal pain, not specifically heartburn. D) Ulcerative colitis is a type of inflammatory bowel disease that affects the colon and rectum, and it does not typically cause heartburn.

4. A medication must be taken twice daily, 12 hours apart. If the first dose is at 8:00 AM, what is the most convenient time for the second dose to avoid disrupting sleep?

• A. 4:00 PM
• B. 6:00 PM
• C. 8:00 PM
• D. 10:00 PM

Correct answer: B

Rationale: Rationale: To take the medication 12 hours apart from the first dose at 8:00 AM, the second dose should be taken at 8:00 PM. However, to avoid disrupting sleep, it is recommended to take the second dose a bit earlier. Taking the second dose at 6:00 PM ensures that the medication is still being taken 12 hours apart while allowing for a buffer before bedtime to avoid any potential disruptions to sleep.

5. What is the 3D structure of a protein called?

• A. Tertiary structure
• B. Secondary structure
• C. Primary structure
• D. Quaternary structure

Correct answer: A

Rationale: Rationale: - Primary structure refers to the linear sequence of amino acids in a protein. - Secondary structure refers to local folded structures within a protein, such as alpha helices and beta sheets. - Tertiary structure is the overall 3D shape of a protein, which is determined by interactions between amino acid side chains and the environment. - Quaternary structure refers to the arrangement of multiple protein subunits in a protein complex. Therefore, the 3D structure of a protein is called the tertiary structure because it represents the overall folding of the protein into a specific shape.

6. 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.
