A nurse is caring for a client who is pregnant and Rh-negative. The nurse should plan to monitor which of the following maternal laboratory test results to determine maternal-fetal blood incompatibility?
Homocysteine.
Indirect Coombs.
Erythropoietin.
aPTT.
The Correct Answer is B
The indirect Coombs test is used to detect antibodies against foreign red blood cells in the maternal serum. This test can help identify maternal-fetal blood incompatibility, which can cause hemolytic disease of the newborn.
Choice A is wrong because homocysteine is a type of amino acid and is not related to blood compatibility.
Choice C is incorrect because erythropoietin is a hormone that regulates red blood cell production and is not a specific test for detecting maternal-fetal blood incompatibility.
Choice D is not the correct answer as aPTT (activated partial thromboplastin time) is a test used to evaluate blood clotting factors and is not directly related to monitoring maternal-fetal blood incompatibility.

Correct Answer is B
Explanation
Verapamil is a calcium channel blocker that can lower blood pressure and cause dizziness or fainting, especially when standing up from a sitting or lying position. Changing positions slowly can help prevent these symptoms.
Choice A is wrong because palpitations are not an expected side effect of verapamil, but rather a sign of a possible overdose or a serious heart problem that requires medical attention.
Choice C is wrong because verapamil should be taken with food or milk to avoid stomach upset and increase absorption.
Choice D is wrong because verapamil does not cause weight loss, but rather weight gain as a possible side effect.
Increasing calorie intake is not necessary and may worsen other health conditions such as diabetes or high cholesterol.
Correct Answer is A
Explanation
Encourage the client to help care for their surgical incision. This can help the client accept the body image change and promote healing.
Choice B is wrong because suggesting that the client decide about reconstruction as soon as possible can pressure the client and interfere with their coping process.
Choice C is wrong because postponing referrals to support services until the client requests them can delay the client’s emotional recovery and increase their isolation.
Choice D is wrong because avoiding talking to the client about the surgery can indicate that the nurse is uncomfortable with the topic and discourage the client from expressing their feelings.
