A nurse is reviewing laboratory results for a preterm infant who has anemia of prematurity.
Which of the following values should the nurse report to the provider?
Hemoglobin 10 g/dL
Hematocrit 30%
Reticulocyte count 2%
Platelet count 150,000/mm3.
The Correct Answer is C
Reticulocyte count 2%.
A reticulocyte count measures the percentage of immature red blood cells (RBCs) in the blood. A low reticulocyte count indicates that the bone marrow is not producing enough RBCs, which is a characteristic feature of anemia of prematurity (AOP). A normal reticulocyte count for preterm infants is 3-6%.
Choice A is wrong because hemoglobin 10 g/dL is within the normal range for preterm infants.
Hemoglobin is the protein in RBCs that carries oxygen.
A low hemoglobin level indicates anemia.
Choice B is wrong because hematocrit 30% is within the normal range for preterm infants.
Hematocrit is the percentage of blood volume that is occupied by RBCs.
A low hematocrit level indicates anemia.
Choice D is wrong because platelet count 150,000/mm3 is within the normal range for preterm infants.
Platelets are cell fragments that help with blood clotting.
A low platelet count indicates thrombocytopenia, which is a different condition from anemia.

Correct Answer is A
Explanation
“We need to monitor your kidney function because SLE can cause glomerulonephritis.” Glomerulonephritis is kidney inflammation caused by SLE that can damage the filtering units of the kidneys called glomeruli.SLE is an autoimmune disease that can affect various organs and tissues, including the kidneys.About half of the people with lupus experience kidney involvement, which can lead to kidney failure if not treated.
Therefore, it is important to monitor the kidney function of people with SLE.
Choice B is wrong because SLE does not cause hepatic necrosis, which is the death of liver cells.SLE can cause inflammation of the liver, but this is less common and less severe than kidney involvement.
Choice C is wrong because SLE does not cause hypothyroidism, which is a condition where the thyroid gland does not produce enough thyroid hormones.
SLE can affect the thyroid gland, but this is rare and usually does not affect the thyroid function.
Choice D is wrong because SLE does not cause diabetes mellitus, which is a condition where the body cannot regulate blood sugar levels.
SLE can cause inflammation of the pancreas, but this is uncommon and usually does not affect the insulin production.
Correct Answer is A
Explanation
Absent Moro reflex on the affected side indicates a possible injury to the brachial plexus, which is the nerve network that controls the movements and sensations of the shoulder, arm, hand and fingers.Shoulder dystocia can cause brachial plexus injuries when the baby’s shoulder gets stuck behind the mother’s pubic bone during delivery.
Choice B is wrong because flaccid paralysis of both lower extremities is not a common complication of shoulder dystocia.
It could be a sign of spinal cord injury or other neurological disorders.
Choice C is wrong because facial asymmetry when crying or smiling is a sign of facial nerve palsy, which can occur due to compression of the facial nerve during delivery.
It is not specific to shoulder dystocia.
Choice D is wrong because inability to suck or swallow is not a typical sign of shoulder dystocia.
It could be caused by other factors such as prematurity, neurological problems, or congenital anomalies.
Normal ranges for Moro reflex are present at birth and disappear by 4 to 6 months of age.
Normal ranges for facial nerve function are symmetrical movements of both sides of the face.
Normal ranges for sucking and swallowing are coordinated and effective feeding within the first hour after birth.
