The most common neonatal sepsis and meningitis infections seen within 24 hours after birth are caused by which organism?
- A. Candida albicans
- B. Chlamydia trachomatis
- C. Escherichia coli
- D. Group B beta-hemolytic streptococci
Correct Answer: C
Rationale: Escherichia coli is the most common cause of early-onset neonatal sepsis and meningitis within 24 hours after birth. E. coli can be transmitted from the mother to the infant during delivery, particularly if there is prolonged rupture of membranes or maternal infection. Infections caused by E. coli in newborns can be severe and life-threatening. It is important to identify and promptly treat infections caused by E. coli in neonates to prevent complications and improve outcomes.
As part of the treatment for heart failure, the child takes the diuretic furosemide (Lasix). As part of teaching home care, the nurse encourages the family to give the child foods such as bananas, oranges, and leafy vegetables. These foods are recommended because they are high in which nutrient?
- A. Chlorides
- B. Potassium
- C. Sodium
- D. Vitamins
Correct Answer: B
Rationale: The diuretic furosemide (Lasix) can cause the loss of potassium in the body through increased urination. Potassium is an important mineral that helps maintain normal heart function. Therefore, it is essential to consume foods rich in potassium, such as bananas, oranges, and leafy vegetables, to prevent potassium deficiency (hypokalemia) and support heart health, especially in individuals taking diuretics for conditions like heart failure.

- A. 1 month
- B. 1 to 2 months
- C. 3 to 4 months

Correct Answer: D
Rationale: By 6 months of age, infants should be able to fix on and follow a target with their eyes. This behavior is indicative of normal visual development in infants. It typically signifies that the infant's visual acuity is developing as expected. Therefore, by the age of 6 months, most infants should demonstrate the ability to focus on and track objects within their field of vision.
