Nursing Elites

1. A nurse is providing teaching to a client with gastroesophageal reflux. Which of the following statements by the client indicates a need for further teaching?

• A. I should elevate the head of my bed while sleeping.
• B. I drink no more than 4 cups of coffee a day.
• C. I take my time when I am eating.
• D. I avoid foods and drinks made with chocolate.

Correct answer: B

Rationale: The correct answer is B: 'I drink no more than 4 cups of coffee a day.' Excessive coffee consumption can aggravate gastroesophageal reflux due to its acidic nature. Choices A, C, and D are all appropriate self-care measures for managing gastroesophageal reflux. Elevating the head of the bed while sleeping helps prevent acid reflux, eating slowly can reduce reflux episodes, and avoiding trigger foods like chocolate can help alleviate symptoms.

2. Which nutrient is most closely associated with the prevention of neural tube defects in a developing fetus for a woman planning to become pregnant?

• A. Calcium
• B. Folate
• C. Vitamin A
• D. Choline

Correct answer: B

Rationale: The correct answer is folate. Folate, also known as Vitamin B9, is vital for the prevention of neural tube defects in the developing fetus. It is primarily responsible for the creation and repair of DNA, which is essential during rapid growth stages such as pregnancy. While nutrients like calcium, vitamin A, and choline are important for pregnancy, they are not as directly linked to preventing neural tube defects as folate. Calcium is crucial for the baby's bone and teeth development. Vitamin A is essential for vision, immune function, and cellular growth. Choline supports brain development and neural functioning. However, none of these nutrients have the same direct impact on preventing neural tube defects as folate.

3. Electrolytes create _____, which is caused by water following electrolytes within or between cells.

• A. energy
• B. active transport
• C. passive diffusion
• D. osmotic pressure

Correct answer: D

Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.

4. What is the approximate energy value of alcohol?

• A. 3 kcal/g
• B. 7 kcal/g
• C. 10 kcal/g
• D. 25 kcal/g

Correct answer: B

Rationale: The correct answer is B: 7 kcal/g. Alcohol provides approximately 7 kilocalories per gram, making it a significant source of energy or 'empty calories' in the diet that do not contain any nutrients. 'Empty calories' refer to the calorie content without the presence of essential nutrients. Choices A, C, and D are incorrect. The energy values of 3 kcal/g, 10 kcal/g, and 25 kcal/g are not accurate for alcohol; instead, they may pertain to other nutrients such as carbohydrates (approximately 4 kcal/g), fats (approximately 9 kcal/g), and oils (approximately 9 kcal/g).

5. Which bond is formed by a positively charged metal ion and negatively charged nonmetal ion?

• A. Ionic bond
• B. Covalent bond
• C. Functional group
• D. Metallic bond

Correct answer: A

Rationale: The correct answer is an ionic bond. An ionic bond is formed when a positively charged metal ion joins with a negatively charged nonmetal ion, resulting in a transfer of electrons. In contrast, a covalent bond involves sharing electrons between atoms rather than complete transfer. Functional groups are specific groups of atoms within molecules that determine the molecule's chemical properties. Metallic bonds occur between metal atoms where electrons are shared across a delocalized electron cloud.
