A nurse is feeding a client who has heart failure. Which of the following findings indicates that the client is gaining fluid volume excess?
Creatinine 1.3 mg/dL
BNP 300 pg/mL
Potassium 3.5 mEq/L
Sodium 140 mEq/L
The Correct Answer is B
Choice A reason: Creatinine 1.3 mg/dL is slightly elevated, but it does not indicate fluid volume excess. Creatinine is a waste product of muscle metabolism that is filtered by the kidneys. High creatinine levels can indicate kidney damage or impaired renal function.
Choice B reason: BNP 300 pg/mL is high and indicates fluid volume excess. BNP stands for brain natriuretic peptide, which is a hormone released by the heart when it is stretched by increased blood volume or pressure. High BNP levels can indicate heart failure or fluid overload.
Choice C reason: Potassium 3.5 mEq/L is within the normal range (3.5-5.0), and it does not indicate fluid volume excess. Potassium is an electrolyte that helps regulate nerve and muscle function, especially the heart. Low or high potassium levels can cause cardiac arrhythmias, muscle weakness, or paralysis.
Choice D reason: Sodium 140 mEq/L is within the normal range (135-145), and it does not indicate fluid volume excess. Sodium is an electrolyte that helps maintain fluid balance, blood pressure, and nerve impulses. Low or high sodium levels can cause confusion, seizures, or coma.

Correct Answer is A
Explanation
Choice A reason: Alternating the first breast that is offered to the baby with each feeding is a good practice for breastfeeding because it can ensure equal stimulation and drainage of both breasts, which can prevent engorgement, mastitis, or low milk supply. Alternating breasts can also provide the baby with both foremilk and hindmilk, which have different compositions and benefits.
Choice B reason: Storing breast milk in the refrigerator up to 48 hours is not a good practice for breastfeeding because it can reduce the quality and safety of the milk. Breast milk should be stored in the refrigerator for no longer than 24 hours or in the freezer for no longer than 6 months. Breast milk should also be stored in clean, sterile containers and labeled with the date and time of expression.
Choice C reason: Nursing the baby once every 4 hours is not a good practice for breastfeeding because it can decrease the milk production and supply, which can affect the growth and development of the baby. Breastfeeding should be done on demand or at least every 2 to 3 hours during the day and every 3 to 4 hours at night. Breastfeeding should also last for at least 10 to 15 minutes per breast or until the baby is satisfied.
Choice D reason: Offering the baby water between feedings is not a good practice for breastfeeding because it can interfere with the baby's appetite and intake of breast milk, which can cause dehydration, malnutrition, or failure to thrive. Breast milk contains enough water and nutrients to meet the baby's needs for the first six months of life. Water should be avoided or limited until the baby starts solid foods.
Correct Answer is C
Explanation
Choice A reason: 1/2 cup cooked broccoli contains about 2.6 grams of fiber, which is moderate compared to other foods. Broccoli is also a good source of vitamin C, folate, and antioxidants.
Choice B reason: 1 slice whole wheat bread contains about 2 grams of fiber, which is low compared to other foods. Whole wheat bread is also a good source of carbohydrates, B vitamins, and magnesium.
Choice C reason: 1 medium apple with peel contains about 4.4 grams of fiber, which is high compared to other foods. Apple is also a good source of vitamin C, potassium, and phytochemicals.
Choice D reason: 1/2 cup corn flakes with skim milk contains about 0.5 grams of fiber, which is very low compared to other foods. Corn flakes are also high in sugar and low in nutrients, while skim milk is a good source of protein and calcium.
