Nursing Elites

1. Churns chyme and has an environment of pH2; holds 4-6 cups of food:

• A. stomach
• B. pancreas
• C. large intestine
• D. small intestine

Correct answer: A

Rationale: The stomach churns food into chyme and has a highly acidic environment (pH 2) to aid in the digestion of proteins and other nutrients.

2. What physiologic role does magnesium play in the body?

• A. Blood clotting, transmission of nerve impulses, muscle contraction and relaxation
• B. Calcium homeostasis, structural integrity of heart muscle
• C. No known metabolic function, caries-preventing properties
• D. ATP energy release; metabolism of fats, carbohydrates, proteins; regulates acid-base balance

Correct answer: B

Rationale: The correct answer is B. Magnesium plays an important role in maintaining calcium homeostasis and preventing skeletal abnormalities. It is involved in more than 300 enzymatic reactions, including energy metabolism, insulin activity, and glucose use. Magnesium is vital to the structural integrity of heart muscle and other muscles and nerves. While magnesium does play a role in blood clotting, nerve impulses, muscle contraction, relaxation, ATP energy release, and metabolism of fats, carbohydrates, proteins, the primary physiologic role of magnesium in the body is related to calcium homeostasis and maintaining the structural integrity of the heart muscle. Choice A is incorrect because it includes functions of magnesium, but they are not its primary physiologic role. Choice C is incorrect as magnesium has several known metabolic functions. Choice D is incorrect because although magnesium is involved in ATP energy release and metabolism, its primary role is related to calcium homeostasis and structural integrity of muscle.

3. A client is planning eating strategies with a nurse who has nausea from equilibrium imbalance. Which of the following strategies should the nurse recommend?

• A. Encourage the client to eat, even if nauseated.
• B. Provide low-fat carbohydrates with meals.
• C. Limit fluid intake between meals.
• D. Serve hot foods at mealtime.

Correct answer: B

Rationale: The correct answer is B: Provide low-fat carbohydrates with meals. Low-fat carbohydrates are easier to digest and can help manage nausea without overloading the digestive system. Encouraging the client to eat even if nauseated (Choice A) may worsen their symptoms. Limiting fluid intake between meals (Choice C) may lead to dehydration, which can exacerbate nausea. Serving hot foods at mealtime (Choice D) may not necessarily address the underlying issue of equilibrium imbalance causing nausea.

4. The mother of a drug dependent would never consider referring her son to a drug rehabilitation agency because she fears her son might just become worse while relating with other drug users. The mother’s behavior can be described as:

• A. Unhelpful
• B. Codependent
• C. Caretaking
• D. Supportive

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.

5. A nurse is providing teaching to the parent of an infant about introducing solid foods. The nurse should recommend that which of the following foods be introduced first?

• A. Strained fruits
• B. Pureed meats
• C. Cooked egg whites
• D. Iron-fortified cereal

Correct answer: D

Rationale: When introducing solid foods to infants, it is recommended to start with iron-fortified cereal as it is easily digestible and a good source of iron, an important nutrient for infants around 6 months of age. Strained fruits are usually introduced later due to their natural sugars. Pureed meats can be introduced after iron-fortified cereals to provide additional protein and iron. Cooked egg whites should be avoided until the infant is at least one year old to reduce the risk of allergies.
