Nursing Elites

1. A nurse is instructing teenage girls on the importance of adequate calcium intake throughout their life span to prevent complications. Which complication should the nurse include in the teaching?

• A. Goiter
• B. Osteoporosis
• C. Heart disease
• D. Dental caries

Correct answer: B

Rationale: The correct answer is B: Osteoporosis. Adequate calcium intake throughout life helps prevent osteoporosis, a condition characterized by weak and brittle bones, which is common in older adults. Goiter is caused by an iodine deficiency, not calcium. Heart disease is more related to factors like cholesterol and blood pressure. Dental caries are primarily influenced by oral hygiene and sugar intake, not just calcium.

2. 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.

3. Clients may benefit from slightly higher fat intakes than are normally recommended if they have:

• A. congestive heart failure
• B. cerebrovascular accident
• C. peripheral vascular disease
• D. chronic obstructive pulmonary disease

Correct answer: D

Rationale: In chronic obstructive pulmonary disease (COPD), higher fat intake can be beneficial because it provides more calories with less respiratory burden compared to carbohydrates. Choices A, B, and C are incorrect because congestive heart failure, cerebrovascular accident, and peripheral vascular disease do not specifically benefit from higher fat intakes as in COPD.

4. A patient is admitted to the emergency room and is found to have proteinuria, a low serum albumin level, edema, and elevated blood lipids. Which condition do these symptoms typically associate with?

• A. Nephrotic syndrome
• B. Acute kidney injury
• C. Rejection of a kidney transplant
• D. Renal colic

Correct answer: A

Rationale: The correct answer is A: Nephrotic syndrome. Nephrotic syndrome is characterized by proteinuria (excess protein in urine), hypoalbuminemia (low serum albumin), edema (swelling due to fluid buildup), and hyperlipidemia (elevated blood lipids). These symptoms occur as a result of damage to the kidneys' filtering units. Acute kidney injury, rejection of a kidney transplant, and renal colic do not present with the same combination of symptoms as nephrotic syndrome. Acute kidney injury typically presents with a sudden decrease in kidney function, resulting in a build-up of waste products in the blood. Rejection of a kidney transplant may present with fever, pain at the transplant site, and changes in urine output. Renal colic usually presents with intense pain in the lower back or side, related to kidney stones.

5. Why are LDLs known as the 'bad' type of cholesterol?

• A. LDL (Low-Density Lipoprotein) is considered 'bad' cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis).
• B. Both the statement and the reason are correct but are not related
• C. The statement is correct, but the reason is not correct
• D. The statement is not correct, but the reason is correct

Correct answer: A

Rationale: LDL (Low-Density Lipoprotein) is known as the 'bad' type of cholesterol because it deposits cholesterol on the walls of arteries, leading to plaque formation and narrowing of the arteries (atherosclerosis). This narrowing can restrict blood flow and increase the risk of serious cardiovascular conditions. The statement and the reason are directly related because the adherence of LDL to arterial walls and the subsequent narrowing of the lumen are the primary reasons why it is considered detrimental to heart health. Choice B is incorrect because the statement and reason are related. Choice C is incorrect because both the statement and the reason are correct. Choice D is incorrect because the statement correctly identifies LDL as the 'bad' type of cholesterol due to its actions in the arteries.
