Nursing Elites

1. Which of the following is a good food source of iodine?

• A. Seafood
• B. Lettuce
• C. Broccoli
• D. Pork

Correct answer: A

Rationale: Seafood is a rich source of iodine, essential for maintaining healthy thyroid function and overall metabolic health. While lettuce, broccoli, and pork may contain some iodine, they do not provide as substantial an amount as seafood. Therefore, they are not considered 'good' sources of iodine in comparison.

2. In a patient with osteoporosis, which mineral is essential to prevent further bone loss?

• A. Iron
• B. Phosphorus
• C. Magnesium
• D. Calcium

Correct answer: D

Rationale: Calcium is crucial in preventing bone loss in patients with osteoporosis.

3. Each of the following describes the physiologic roles of water, except one. Which is the exception?

• A. Acts as a solvent for chemical reactions.
• B. Maintains stability of body fluids.
• C. Enables transport of nutrients and excretion of waste.
• D. Regulates temperature by pooling as perspiration on skin.

Correct answer: D

Rationale: The correct answer is D. Water regulates body temperature by evaporating as perspiration from the skin, not by pooling. When sweat evaporates from the skin, it takes away heat, which helps cool the body. Choices A, B, and C are correct because water acts as a solvent for chemical reactions, maintains the stability of body fluids, and enables the transport of nutrients and excretion of waste, respectively.

4. Monosaccharides are converted into glucose in the liver to provide an energy supply to the cells.

• A. Both statements are true
• B. Both statements are false
• C. The first statement is true; the second is false
• D. The first statement is false; the second is true

Correct answer: A

Rationale: Both statements are true. Monosaccharides are indeed converted into glucose in the liver. Glucose, in turn, serves as a primary energy source for cells in the body, providing the necessary fuel for various cellular functions. The liver plays a crucial role in regulating blood glucose levels by converting monosaccharides into glucose and releasing it into the bloodstream when needed. Therefore, option A is the correct choice. Options B, C, and D are incorrect because both statements are accurate in this context.

5. A nurse is providing teaching to the parent of a toddler about appropriate snacks. Which of the following foods should the nurse include?

• A. Sliced bananas
• B. Raw celery
• C. Peanut butter
• D. Grapes

Correct answer: A

Rationale: The correct answer is sliced bananas. Bananas are a good choice for toddlers as they are easy to chew, rich in potassium, and generally well-tolerated. Raw celery (Choice B) may pose a choking hazard due to its fibrous nature. Peanut butter (Choice C) should be avoided as it can also be a choking hazard and may cause an allergic reaction in some children. Grapes (Choice D) are a choking hazard for toddlers due to their size and shape, so they should be cut into smaller pieces or avoided altogether.
