A nurse is teaching a client who has hyperlipidemia and a new prescription for atorvastatin. The nurse should instruct the client to avoid which of the following foods?
Grapefruit
Coffee
Milk
Oatmeal
The Correct Answer is A
A. Grapefruit: Grapefruit inhibits the cytochrome P450 3A4 enzyme in the liver, which is responsible for metabolizing atorvastatin. When this enzyme is blocked, the levels of atorvastatin in the blood can rise increasing the risk of serious side effects such as muscle toxicity and liver damage. Clients taking statins should completely avoid grapefruit to ensure the medication is processed safely and effectively.
B. Coffee: Coffee does not interact with atorvastatin in a clinically significant way. While excessive caffeine intake can have other health implications, it does not affect the metabolism or effectiveness of atorvastatin. Clients with hyperlipidemia may still consume coffee in moderation unless otherwise advised based on other health conditions.
C. Milk: Milk does not interfere with atorvastatin's absorption or metabolism. It is safe to consume while on the medication. In fact, low-fat dairy products can be part of a heart-healthy diet aimed at lowering cholesterol, making milk an acceptable food choice for clients with hyperlipidemia.
D. Oatmeal: Oatmeal is beneficial for clients with hyperlipidemia because it contains soluble fiber, which helps to lower LDL (bad) cholesterol levels. There are no known interactions between oatmeal and atorvastatin. Including oatmeal in the diet supports the therapeutic goals of atorvastatin by promoting heart health.

Correct Answer is ["B","C"]
Explanation
A. Legumes: Legumes, such as beans and lentils, are rich in protein but do not contain all nine essential amino acids in sufficient amounts, making them incomplete proteins. To achieve a complete amino acid profile, legumes must be combined with other protein sources, such as grains. Therefore, legumes are not classified as complete proteins on their own.
B. Eggs: Eggs are a high-quality source of protein and contain all nine essential amino acids in the appropriate proportions needed by the human body. They are considered one of the most biologically complete protein sources and are often used as the reference standard for evaluating protein quality in other foods.
C. Poultry: Poultry, such as chicken and turkey, provides all the essential amino acids required for protein synthesis in the body. It is classified as a complete protein and is a valuable source of high-quality animal protein in the human diet. Poultry supports tissue repair, immune function, and muscle maintenance.
D. Grains: Grains like rice, wheat, and oats contain some essential amino acids but lack others, such as lysine, making them incomplete proteins. To form a complete protein, grains need to be eaten in combination with other sources, such as legumes. Alone, they do not fulfill the criteria for a complete protein.
E. Nuts: Nuts are rich in healthy fats and protein, but they do not contain all essential amino acids in sufficient quantities. Like legumes and grains, nuts are incomplete proteins and must be combined with other plant-based foods to form a complete protein profile. Therefore, they are not included as complete proteins in this context.
Correct Answer is C
Explanation
A. 120 mL (4 oz) sugar-free soda: Sugar-free soda does not contain carbohydrates or glucose, which are necessary to treat hypoglycemia. It is sweetened with artificial sweeteners that do not raise blood glucose levels. Offering this would not correct a hypoglycemic episode and could result in worsening symptoms.
B. Three saltine crackers:Three saltine crackers contain only about 6–7 grams of carbohydrates, which is not enough to effectively manage mild hypoglycemia. A total of 15 grams of fast-acting carbohydrates is needed to raise blood glucose to a safe level. While crackers are useful for long-term blood sugar stabilization, they are not sufficient for initial correction.
C. 120 mL (4 oz) fruit juice: Fruit juice is a fast-acting carbohydrate and is quickly absorbed into the bloodstream, making it effective for treating mild hypoglycemia. Four ounces of juice typically contain approximately 15 grams of carbohydrates, meeting the recommended amount for correcting low blood glucose promptly.
D. Three pieces of hard candy: While hard candy can be used to treat hypoglycemia, three small pieces usually provide only about 9–12 grams of carbohydrates, depending on the brand and size. This may be inadequate to raise blood glucose effectively. The client would likely need 4–5 pieces to meet the 15-gram threshold.
