A patient is diagnosed with anemia. The nurse is educating the patient about dietary sources of iron. Which of the following foods is the best source of iron?
- A. Eggs.
- B. Spinach.
- C. Chicken liver.
- D. Oranges.
Correct Answer: C
Rationale: The correct answer is C: Chicken liver. Chicken liver is the best source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods like spinach or oranges. Eggs do contain iron, but in smaller amounts compared to chicken liver. Oranges, on the other hand, are a source of vitamin C which can enhance iron absorption but do not contain significant amounts of iron themselves.

A nurse is caring for a patient with diabetes who is experiencing diabetic neuropathy. The nurse should prioritize which of the following interventions?
- A. Encouraging regular foot inspections.
- B. Providing additional protein to the diet.
- C. Encouraging weight loss to reduce joint stress.
- D. Administering pain medication for relief.
Correct Answer: A
Rationale: The correct answer is A: Encouraging regular foot inspections. This is the priority intervention because diabetic neuropathy can lead to decreased sensation in the feet, increasing the risk of injury or infection. Regular foot inspections can help detect any issues early and prevent complications.
Incorrect choices:
B: Providing additional protein to the diet - While nutrition is important for overall health, providing additional protein does not directly address the specific issue of diabetic neuropathy.
C: Encouraging weight loss to reduce joint stress - Weight loss may be beneficial for overall health, but it is not the priority intervention for diabetic neuropathy.
D: Administering pain medication for relief - Pain management is important, but addressing the root cause through regular foot inspections is more essential in preventing further complications.
A nurse is caring for a patient with diabetes. The nurse should monitor for which of the following complications?
- A. Hypoglycemia.
- B. Hyperkalemia.
- C. Hypotension.
- D. Hyperglycemia.
Correct Answer: D
Rationale: The correct answer is D: Hyperglycemia. In diabetes, hyperglycemia occurs when blood sugar levels are too high. This can lead to various complications such as diabetic ketoacidosis or hyperosmolar hyperglycemic state. Monitoring for hyperglycemia is crucial to prevent these serious complications.
A: Hypoglycemia is low blood sugar and can also occur in diabetes, but it is not the primary complication to monitor for in this case.
B: Hyperkalemia is high potassium levels and is not a common complication of diabetes unless there are other underlying issues.
C: Hypotension is low blood pressure, which can be a complication of diabetes but is not as directly related to glucose management as hyperglycemia.
In summary, monitoring for hyperglycemia is essential in diabetes care to prevent serious complications associated with high blood sugar levels.
A man has come in to the clinic because he is afraid he might have skin cancer. During the skin assessment, the nurse notices several areas of pigmentation that look greasy, dark, and "stuck on' on his skin. Which of the following is the best prediction?
- A. He probably has senile lentigines, which do not become cancerous.
- B. He probably has actinic keratoses, precursors to basal cell carcinoma.
- C. He probably has acrochordons, precursors to squamous cell carcinoma.
- D. He probably has seborrheic keratosis, which do not become cancerous.
Correct Answer: D
Rationale: The correct answer is D: He probably has seborrheic keratosis, which do not become cancerous. Seborrheic keratosis typically appear as greasy, dark, and "stuck on" pigmented growths on the skin, commonly seen in older adults. They are benign and do not progress to skin cancer. This conclusion is based on the characteristics of seborrheic keratosis and the fact that they are not associated with malignancy.
Choice A (senile lentigines) is incorrect because although they are also common in older adults, they are flat and dark spots rather than raised growths. Choice B (actinic keratoses) is incorrect as they are precancerous lesions related to sun exposure, leading to a risk of developing squamous cell carcinoma, not basal cell carcinoma. Choice C (acrochordons) are skin tags and not precursors to squamous cell carcinoma.
The nurse is obtaining the health history of an 87-year-old woman. Which of the following areas of questioning would be most useful at this time?
- A. Obstetrical history
- B. Childhood illnesses
- C. General health for the past 20 years
- D. Current health promotion activities
Correct Answer: D
Rationale: Rationale:
1. Current health promotion activities are important to assess the patient's preventive measures.
2. At 87 years old, focusing on current habits can help identify areas for improvement.
3. Obstetrical history is irrelevant as the patient is postmenopausal.
4. Childhood illnesses are less relevant compared to current health status.
5. General health for the past 20 years may not reflect current health behaviors.
Which of the following is the best indicator of a patient's nutritional status?
- A. Patient's weight
- B. Serum albumin levels
- C. Patient's food preferences
- D. Number of meals consumed per day
Correct Answer: B
Rationale: The correct answer is B: Serum albumin levels. Serum albumin is a protein produced by the liver and is a key indicator of a patient's nutritional status. Low levels of serum albumin indicate malnutrition or protein deficiency. Monitoring serum albumin levels provides an objective measure of the patient's overall nutritional status.
Choice A (Patient's weight) can be influenced by factors other than nutrition, such as fluid retention or muscle mass. Choice C (Patient's food preferences) does not provide direct information on the patient's actual nutritional intake. Choice D (Number of meals consumed per day) does not account for the quality or quantity of nutrients consumed in those meals.
