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
Examine your testicles after a warm shower.
This is because a warm shower will relax the scrotum and the muscles holding the testicles, making an exam easier. You should gently roll the scrotum with your fingers to feel the surface of each testicle and check for any lumps, bumps, swelling, hardness or other changes.
Choice A is wrong because you should perform the self-examination every month, not every 3 months.
This will help you notice any changes over time.
Choice C is wrong because you should not palpate both testicles firmly with your fingertips. You should use a gentle touch and avoid squeezing or pressing too hard.
Choice D is wrong because you should not apply a cool compress to the scrotum prior to examination. This will make the scrotum contract and tighten, making an exam more difficult.
Correct Answer is D
Explanation
This action indicates that the charge nurse should intervene because adding food coloring to the tube feeding is not recommended and can cause adverse effects such as aspiration, diarrhea, and allergic reactions.
Choice A is wrong because checking the volume of the aspirate is a correct action to assess gastric residual volume and prevent complications such as nausea, vomiting, and aspiration.
Choice B is wrong because checking the pH of the aspirate is a correct action to verify the placement of the NG tube and prevent accidental administration of enteral feeding into the lungs.
Choice C is wrong because administering 15 mL of water before administering the feeding is a correct action to flush the NG tube and prevent clogging.
Normal ranges for gastric residual volume are less than 250 mL for adults and less than 5 mL/kg for children. Normal ranges for pH of gastric aspirate are less than 5.5 for adults and less than 4 for children.
