1. Which mineral is a principal component of cell membranes?

• A. phosphorus
• B. magnesium
• C. iron
• D. iodine

Correct answer: A

Rationale: Phosphorus is the correct answer. It is a key component of cell membranes, being part of the phospholipid bilayer that provides structure and controls the movement of substances in and out of cells. Magnesium, iron, and iodine do not serve as principal components of cell membranes. Magnesium is involved in various enzymatic reactions, iron is essential for oxygen transport, and iodine plays a role in thyroid hormone synthesis.

2. In cleaning the stoma, the nurse would use which of the following cleaning mediums?

• A. Hydrogen Peroxide, water and mild soap
• B. Providone Iodine, water and mild soap
• C. Alcohol, water and mild soap
• D. Mild soap and water

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

3. A nurse is teaching a client who needs to increase their daily fluid intake. Which of the following foods has the highest percentage of water by weight?

• A. Yogurt
• B. Milk
• C. Lettuce
• D. Honey

Correct answer: C

Rationale: The correct answer is Lettuce. Lettuce has the highest percentage of water by weight among the options provided, making it an excellent choice to increase fluid intake. Yogurt and milk have some water content but are not as high in water percentage as lettuce. Honey, on the other hand, contains very little water and is not a good choice for increasing fluid intake.

4. 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.

5. What is the primary food safety concern for a patient undergoing chemotherapy?

• A. Possible food allergy reactions
• B. Possible food-drug interactions
• C. Possible pesticide residue
• D. Potential risk of foodborne illness

Correct answer: D

Rationale: The correct answer is D: Potential risk of foodborne illness. Patients undergoing chemotherapy have compromised immune systems, making them more susceptible to foodborne illnesses. Chemotherapy can reduce the count of white blood cells, which impairs the body's ability to fight off infections from bacteria or other pathogens that might be present in food. Therefore, the prevention of foodborne illnesses is a critical concern for these patients. Choices A, B, and C, while they represent valid concerns for food safety in general, are not the primary concern for patients undergoing chemotherapy. These patients are at a heightened risk of experiencing severe complications from foodborne illnesses, making it a more significant concern than potential food allergies, food-drug interactions, or pesticide residues.
