Wellness Q&A with Rationale | Chamberlain

1. A nurse is teaching a pregnant client with a BMI of 22 about recommended weight gain.
Which statement by the nurse is correct?
A. You should aim to gain between 11 to 20 pounds during your pregnancy.
B. A total weight gain of 25 to 35 pounds is recommended for a normal BMI.
C. You should not gain any weight during the first trimester of pregnancy.
D. Weight gain is not a priority as long as you take your prenatal vitamins.
Correct Answer: B
Explanation: For a woman with a normal pre-pregnancy BMI (18.5-24.9), the Institute of
Medicine recommends a total gain of 25-35 pounds. This range supports fetal growth and
maternal health requirements throughout the gestation period. Proper weight
management reduces the risk of complications such as gestational diabetes or low birth
weight.
2. Which nutrient is most critical to supplement before and during early pregnancy to prevent
neural tube defects?
A. Vitamin C
B. Folic Acid
,C. Calcium
D. Vitamin A
Correct Answer: B
Explanation: Folic acid is essential for DNA synthesis and the proper closure of the neural
tube in the developing fetus. Adequate intake of 400-800 mcg daily before conception and
during the first trimester significantly reduces the incidence of spina bifida. This nutrient is
a primary focus of prenatal nutritional counseling in the NR228 curriculum.
3. A nurse is caring for a client receiving total parenteral nutrition (TPN). Which laboratory
value is the priority to monitor?
A. Serum sodium
B. Blood glucose
C. Serum calcium
D. Hemoglobin
Correct Answer: B
Explanation: TPN solutions contain high concentrations of dextrose, which places the
client at significant risk for hyperglycemia. Monitoring blood glucose every 6 hours is a
standard nursing intervention to ensure metabolic stability and adjust insulin if needed.
Consistent monitoring helps prevent osmotic diuresis and other complications associated
with high sugar loads.
, 4. Which of the following is a characteristic of the DASH diet used to manage hypertension?
A. High intake of red meats and full-fat dairy
B. Restriction of potassium-rich foods
C. Increased consumption of fruits, vegetables, and low-fat dairy
D. Elimination of all dietary carbohydrates
Correct Answer: C
Explanation: The DASH (Dietary Approaches to Stop Hypertension) diet emphasizes foods
rich in potassium, calcium, and magnesium. It focuses on reducing sodium while increasing
plant-based foods and lean proteins to lower blood pressure naturally. Clinical studies have
proven this dietary pattern is highly effective in managing cardiovascular health.
5. An infant is expected to double their birth weight by what age?
A. 2 months
B. 12 months
C. 6 months
D. 9 months
Correct Answer: C
Explanation: Healthy infants typically double their birth weight by 4 to 6 months of age
and triple it by their first birthday. This rapid growth period requires high energy and
