The nurse is caring for a patient with pneumonia. Which lab abnormality is most concerning?

decreased serum creatinine

elevated white blood cell count

protein in urinalysis

decreased serum potassium

Answer and Explanation

The Correct Answer is B

B. An elevated white blood cell (WBC) count, specifically an elevation in the neutrophil count (neutrophilia), is commonly seen in pneumonia. It indicates an inflammatory response to the infection and is a typical finding in bacterial pneumonia.
A. A decreased serum creatinine level is not typically associated with pneumonia and may not be directly related to the condition. In fact, it may suggest impaired kidney function or dehydration, but it is not a concerning lab abnormality specifically related to pneumonia.
C. Protein in the urine (proteinuria) may be present in various conditions, including kidney disease, urinary tract infections, and certain systemic illnesses. While it can sometimes be seen in severe cases of pneumonia, it is not a specific or common finding associated with the condition.
D. Decreased serum potassium levels are not typically associated with pneumonia itself. However, certain factors related to pneumonia treatment or complications, such as the use of diuretics or vomiting, could lead to hypokalemia. While hypokalemia can have serious consequences, it is not directly related to the severity of pneumonia.

Correct Answer is A

Explanation

A. Insulin is typically administered via injections or an insulin pump, not in pill form. Individuals with type 1 diabetes require exogenous insulin to manage their blood sugar levels because their pancreas does not produce insulin.
B. Carbohydrate counting is a fundamental skill for individuals with diabetes, as it allows them to adjust their insulin dosage to match their carbohydrate intake, thereby helping to manage blood sugar levels.
C. Regular foot monitoring is crucial for individuals with diabetes, as they are at increased risk of developing foot problems due to nerve damage (neuropathy) and poor circulation.
D. Maintaining blood glucose levels within the target range (80-130 mg/dL before meals) helps reduce the risk of both short-term complications (e.g., hypoglycemia) and long-term complications (e.g., neuropathy, retinopathy) associated with diabetes.

A. Oatmeal with artificial sweetener, whole-grain toast, tea B. Two eggs two strips of bacon, orange juice, coffee C. One slice whole-grain toast with peanut butter, skim milk, orange juice D. One half grapefruit, cranberry juice, bagel with sugar-free jelly

Correct Answer is A

Explanation

A. Oatmeal is a good source of fiber, which can help manage blood sugar levels. Whole-grain toast provides complex carbohydrates and fiber, and using an artificial sweetener in oatmeal reduces sugar intake. Tea is a good beverage choice as it does not contain sugar or calories if not sweetened.
B. This option is less appropriate for a patient with diabetes. While eggs are a good source of protein, bacon is high in saturated fat and sodium, which is not ideal for cardiovascular health. Orange juice contains a high amount of natural sugar and can cause a rapid increase in blood glucose levels. Coffee is fine if consumed without sugar or high-fat creamers.
C. Whole-grain toast with peanut butter provides fiber, protein, and healthy fats, which are beneficial. Skim milk is a good source of calcium and protein. However, the inclusion of orange juice is problematic due to its high sugar content, which can spike blood sugar levels.

D. While grapefruit is a low-sugar fruit, cranberry juice often contains added sugars and can increase blood glucose levels. A bagel, even with sugar-free jelly, is high in refined carbohydrates, which can cause a rapid rise in blood sugar.
