A nurse in a prenatal clinic is teaching a group of clients about nutrition requirements during lactation. Which of the following statements should the nurse make?

The recommended intake of iron increases.

Zinc intake should be at least 12 mg per day.

Calcium intake should be at least 2,000 mg per day.

The recommended intake of folic acid remains the same as for pregnant women.

Answer and Explanation

The Correct Answer is B

Choice A Reason:
The recommended intake of iron does not necessarily increase during lactation. In fact, the iron requirement may decrease because menstruation usually ceases, reducing iron loss. However, maintaining adequate iron intake is still important for overall health and to support the baby's growth.

Choice B Reason:
Zinc is crucial for immune function, cell division, and growth, making it an important nutrient during lactation. The recommended dietary allowance (RDA) for zinc for lactating women is indeed higher than for non-pregnant, non-lactating women, with an RDA of about 12 mg per day.

Choice C Reason:
While calcium is important for bone health, the recommended intake for lactating women is not as high as 2,000 mg per day. The RDA for calcium for lactating women is about 1,000 mg per day, similar to that for non-lactating women.

Choice D Reason:
The recommended intake of folic acid does not remain the same as for pregnant women. During pregnancy, the RDA for folic acid is higher to prevent neural tube defects. While folic acid is still important during lactation for cell growth and DNA synthesis, the requirement is slightly lower than during pregnancy.

Correct Answer is B

Explanation

Choice A reason:
Magnesium sulfate is used in the management of severe preeclampsia primarily for seizure prophylaxis. One of the key side effects of magnesium sulfate is its impact on neuromuscular transmission, leading to diminished deep-tendon reflexes as serum magnesium levels rise. The therapeutic range for anticonvulsant prophylaxis is typically between 5-8 mg/dL. Reflexes may begin to diminish when serum levels reach 8-12 mg/dL, indicating potential magnesium toxicity. Therefore, diminished reflexes are a warning sign to reassess the infusion rate and possibly reduce or discontinue the medication.

Choice B reason:
A respiratory rate of 16 breaths per minute falls within the normal adult range and suggests that the client's respiratory system is not being adversely affected by the magnesium sulfate infusion. Respiratory rate is a critical parameter to monitor during magnesium sulfate therapy, as respiratory depression is a serious side effect of magnesium toxicity. Maintaining a normal respiratory rate indicates that it is safe to continue the infusion at the current rate.

Choice C reason:
While a urine output of 50 mL/hr is on the lower end of the normal range, it is still considered adequate for most adults. In the setting of magnesium sulfate therapy for severe preeclampsia, maintaining adequate urine output is essential for ensuring that the kidneys can excrete the magnesium to prevent accumulation and toxicity. If urine output decreases significantly, it may necessitate reevaluation of the infusion rate or additional interventions to support renal function.

Choice D reason:
A heart rate of 56 beats per minute is slightly bradycardic but may not be clinically significant if the client is asymptomatic. However, magnesium has a direct effect on cardiac function, and high levels can lead to bradycardia and other cardiac conduction abnormalities. It is important to monitor the client's heart rate and rhythm during magnesium sulfate therapy to detect any early signs of cardiac involvement due to magnesium toxicity.

A. Type 1 diabetes mellitus B. Intrauterine growth restriction C. Hearing loss D. Congenital heart defects

Correct Answer is B

Explanation

Choice A reason:
Type 1 diabetes mellitus is generally not directly associated with maternal smoking. It is an autoimmune condition where the pancreas produces little to no insulin. Risk factors for Type 1 diabetes include family history and possibly environmental factors, but maternal smoking is not a recognized risk factor.

Choice B reason:
Intrauterine growth restriction (IUGR) refers to poor growth of a fetus while in the mother's womb during pregnancy. The causes of IUGR are many, but maternal smoking is a well-documented risk factor. Smoking during pregnancy can reduce oxygen and nutrient delivery to the fetus, leading to low birth weight and other complications.

Choice C reason:
While smoking during pregnancy can increase the risk of various health issues, there is no direct and consistent evidence linking it to hearing loss in newborns. Hearing loss in newborns can be due to genetic factors, infections during pregnancy, or complications at birth.

Choice D reason:
Congenital heart defects are the most common type of birth defect, and their causes can be multifactorial, including genetic and environmental factors. Maternal smoking has been associated with an increased risk of certain congenital heart defects, but the relationship is not as strong as with intrauterine growth restriction.
