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.

Answer and Explanation

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 D

Explanation

Insulin lispro was administered to a client immediately before bed. This is a situation that requires the completion of an incident report because insulin lispro is a rapid-acting insulin that should be given within 15 minutes before or after a meal. Giving it immediately before bed can cause hypoglycemia (low blood sugar) during the night, which can be dangerous for the client.

Choice A is wrong because nitroglycerin transdermal is a medication used to prevent angina (chest pain) and can be applied to a client’s chest as prescribed.

Choice B is wrong because cefotaxime is an antibiotic that can be administered to a client after obtaining blood cultures to treat an infection.

Choice C is wrong because digoxin is a medication used to treat heart failure and atrial fibrillation and can be administered to a client who has a heart rate of 64/min, which is within the normal range of 60 to 100 beats per minute.

A. Muscle irritability. B. Constipation. C. Hypoglycemia. D. Increased BP.

Correct Answer is A

Explanation

Muscle irritability. A client with a lithium level of

2.0 mEq/L has severe lithium toxicity, which can cause muscle irritability, tremors, seizures, and other neurological symptoms. The normal therapeutic range for lithium is 0.8-1.2 mEq/L.

Choice B is wrong because constipation is not a sign of lithium toxicity, but rather a possible side effect of lithium therapy at lower doses.

Choice C is wrong because hypoglycemia is not a sign of lithium toxicity, but rather a possible complication of diabetes or other conditions that affect blood sugar levels.

Choice D is wrong because increased blood pressure is not a sign of lithium toxicity, but rather a possible risk factor for cardiovascular disease or other conditions that affect blood vessels.
