Nursing Elites

1. Which organ absorbs water and vitamin K and may be affected by ulcerative colitis?

• A. Stomach
• B. Pancreas
• C. Large intestine
• D. Small intestine

Correct answer: C

Rationale: The large intestine is the organ that is primarily responsible for the absorption of water and vitamin K in the human body. A disease like ulcerative colitis can disrupt these functions by causing inflammation and ulcers in the lining of the large intestine, leading to digestive issues. The stomach (Choice A) primarily functions to break down and digest food, not to absorb water and vitamins. The pancreas (Choice B) secretes enzymes to aid in digestion and hormones to regulate blood sugar, but does not absorb water and vitamins. The small intestine (Choice D) is primarily responsible for absorbing nutrients from digested food, but not specifically water and vitamin K. Therefore, these other choices are incorrect.

2. Of the following neurotransmitters, which demonstrates inhibitory action, helps control mood and sleep, and inhibits pain pathways?

• A. Serotonin
• B. Enkephalin
• C. Norepinephrine
• D. Acetylcholine

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

3. A mother asks about healthy snacks for her three children under 4 years old. All are wise choices the dental hygienist can recommend, except one. Which is the exception?

• A. Low-fat milk or yogurt
• B. Whole-grain cereals
• C. Raw vegetable sticks
• D. Nuts and seeds

Correct answer: D

Rationale: Nuts and seeds pose a choking hazard for children under 4 years old, making them an unsafe snack choice for young children. While low-fat milk or yogurt, whole-grain cereals, and raw vegetable sticks are healthy snack options suitable for children under 4 years old, nuts and seeds should be avoided due to the risk of choking, especially in young children who may not have fully developed chewing abilities.

4. Which of the following ethical principles refers to the duty to do good?

• A. Beneficence
• B. Fidelity
• C. Veracity
• D. Nonmaleficence

Correct answer: B

Rationale: Nursing interventions should be grounded in a deep understanding of the physiological processes involved, ensuring that care provided is both effective and efficient.

5. What is the desirable resting systolic blood pressure for adults?

• A. <130 mmHg>
• B. <105 mmHg>
• C. <120 mmHg>
• D. <140 mmHg>

Correct answer: C

Rationale: The desirable resting systolic blood pressure for adults is less than 120 mmHg. This blood pressure is associated with a lower risk of cardiovascular disease. Measurements higher than 120 mmHg (choices A and D) indicate elevated blood pressure, which can lead to hypertension and other health complications if not managed. A reading of less than 105 mmHg (choice B) could indicate low blood pressure, which also poses health risks such as dizziness and fainting.
