Nursing Elites

1. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.

2. When carbohydrates are eliminated from the diet to lose weight, which nutrients are most likely to become insufficient?

• A. Iron, fiber, and protein
• B. Iron, fiber, and vitamin K
• C. Vitamin A and vitamin C
• D. Iron, fiber, and B vitamins

Correct answer: D

Rationale: Iron, fiber, and B vitamins are most likely to become insufficient when carbohydrates are eliminated from the diet to lose weight. Carbohydrates are a primary source of B vitamins and fiber in the diet. Iron can also be obtained from plant-based sources like legumes and whole grains, which are often eliminated when carbohydrates are restricted. Choices A, B, and C are incorrect because protein, vitamin K, vitamin A, and vitamin C are not primarily sourced from carbohydrates and are less likely to become insufficient solely due to carbohydrate elimination.

3. Theresa, a mother with a 2-year-old daughter, asks, 'At what age can I start taking my daughter's blood pressure as a routine procedure, since hypertension is common in our family?' What would your answer be?

• A. At 2 years old, you may
• B. As early as 1 year old
• C. When she's 3 years old
• D. When she's 6 years old

Correct answer: D

Rationale: Regular blood pressure checks generally start from age 3, but in the case of a family history of hypertension, they should start when the child is around 6 years old. This is because the readings will be more reliable and indicative of the child's health condition at this age. The other options are incorrect because they suggest earlier ages for routine blood pressure checks. While blood pressure can be measured at any age, it is not typically included as part of a routine health check-up for very young children unless there are specific health concerns.

4. A nurse is providing discharge teaching for a client who has acute pancreatitis and has a prescription for fat-soluble vitamin supplements. The nurse should instruct the client to take a supplement for which of the following?

• A. Vitamin A
• B. Vitamin B1
• C. Vitamin C
• D. Vitamin B12

Correct answer: A

Rationale: In acute pancreatitis, malabsorption of fat-soluble vitamins can occur due to pancreatic enzyme insufficiency. Vitamin A is a fat-soluble vitamin that may need supplementation in this case. Vitamin B1 (thiamine), Vitamin C, and Vitamin B12 are water-soluble vitamins and are not typically affected by pancreatic enzyme insufficiency in acute pancreatitis. Therefore, the correct supplement for the client with acute pancreatitis is Vitamin A.

5. A nurse is caring for a client following an appendectomy. The nurse verifies the postoperative prescription which reads, 'Discontinue NPO status; advance diet as tolerated.' Which of the following are appropriate for the nurse to offer the client? (SATA)

• A. Wheat toast
• B. Applesauce
• C. Applesauce, Chicken broth
• D. Chicken broth

Correct answer: C

Rationale: The correct answer is C: Applesauce and chicken broth. After an appendectomy, patients are typically started on a clear liquid diet before advancing to more solid foods. Applesauce and chicken broth are part of a low-residue diet that is easily digestible and gentle on the digestive system, making them suitable choices for a client following surgery. Wheat toast may be too heavy and fibrous initially, while other solid foods should be introduced gradually to prevent gastrointestinal upset.
