A nurse is reinforcing teaching with a client who is at 18 weeks of gestation and requires an increased intake of iron. Which of the following foods should the nurse recommend as the best source of iron?
Carrots.
Chicken breast.
Apples.
Feta cheese.
The Correct Answer is B
Choice A rationale
Carrots, while nutritious and rich in vitamins, are not a significant source of iron. They provide fiber and beta-carotene but do not meet the increased iron needs during pregnancy.
Choice B rationale
Chicken breast is an excellent source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Consuming chicken breast helps in meeting the increased iron requirements during pregnancy.
Choice C rationale
Apples are healthy and provide essential nutrients and fiber but are not a significant source of iron. They contribute to overall well-being but do not address the specific need for increased iron intake.
Choice D rationale
Feta cheese is a good source of calcium and protein but not iron. While it contributes to nutritional intake during pregnancy, it does not help in meeting the increased iron needs.

Correct Answer is C
Explanation
Choice A rationale
History of methicillin-resistant Staphylococcus aureus (MRSA) is not directly related to the use of a cervical cap. The main concern with a cervical cap is infection, but MRSA history alone doesn't make it a contraindication for this form of contraception.
Choice B rationale
History of thrombophlebitis is more of a concern with hormonal contraceptives due to the risk of blood clots. A cervical cap does not involve hormones, so this condition is not a direct contraindication.
Choice C rationale
History of toxic shock syndrome (TSS) is a contraindication for the use of a cervical cap because the cap can increase the risk of developing TSS again. TSS is associated with prolonged use of barrier contraceptives, which can create an environment that fosters the growth of bacteria responsible for TSS.
Choice D rationale
Type 1 diabetes mellitus is not a direct contraindication for the use of a cervical cap. The concern with diabetes is often related to blood glucose control and potential infections, but it doesn't specifically contraindicate the use of cervical caps.
Correct Answer is A
Explanation
Choice A rationale
Amniocentesis is used to detect fetal genetic abnormalities, such as Down syndrome, by analyzing the amniotic fluid for genetic markers.
Choice B rationale
An empty bladder is required for the test only in late pregnancy to prevent bladder injury; however, in early pregnancy, a full bladder may be required to better visualize the uterus and amniotic fluid.
Choice C rationale
An x-ray is not typically used during the needle placement for amniocentesis. Ultrasound is the preferred method to guide the needle to avoid harm to the fetus and mother.
Choice D rationale
The test does not determine the volume of amniotic fluid; it is used primarily for genetic analysis, assessing fetal lung maturity, and diagnosing certain fetal infections.
