If used consistently and correctly, which of the barrier methods of contraception has the lowest failure rate?
 
  1. Spermicides
  2. Female condoms
  3. Male condoms
  4. Diaphragms

Question 2

Nurses can help parents safely use car seats for their infant by:
 
  1. explaining that they should use a rear-facing car seat in the front seat and a front facing car seat in the rear.
  2. explaining that if an infant reaches the weight limit of a rear-facing seat before the age limit, the infant should be shifted to a front-facing seat.
  3. noting that in a car with passenger-side airbags, the infant is safer in the front seat with the mother.
  4. observing how a preterm low-birth-weight infant does in a car seat, for as long as the drive home takes, before discharge.

Answer to Question 1

3
1. Incorrect. Spermicide failure rates vary from 20 to 50. If used correctly, failure rates for male condoms are only 3 to 5.
2. Incorrect. Female condom failure rates are about 21. If used correctly, failure rates for male condoms are only 3 to 5.
3. Correct. Although typical users might have failure rates of up to 15, if used correctly, failure rates for male condoms are only 3 to 5.
4. Incorrect. Diaphragms with spermicides fail at a 16 rate. If male condoms are used correctly, failure rate is only 3 to 5.

Answer to Question 2

4
1. Incorrect. Use of rear-facing and front-facing car seats is determined by the weight and age of the infant. The safest area of the car is the rear seat.
2. Incorrect. If an infant reaches 20 pounds (weight limit) before age 1 (age limit) he/she should still ride in a rear-facing seat.
3. Incorrect. In cars equipped with airbags, rear-facing car seats must not be placed in the front seat. But infants should be in car seats, not held by a parent.
4. Correct. Preterm, low-birth-weight infants may not sit safely in car seats without mod-ification, such as adding support with blanket rolls.
