A nurse is reinforcing teaching with a client who is at 10 weeks of gestation regarding the purposes of laboratory tests.Which of the following statements by the client indicates an understanding of the teaching?
White blood cell count is an indicator of anemia.
Urine specific gravity identifies my risk for pregnancy-induced hypertension.
Sedimentation rate checks for signs of cancer.
Platelet count identifies if I am at risk for bleeding.
The Correct Answer is D
Choice A rationale
White blood cell count is not an indicator of anemia. It measures immune function and can indicate infection or inflammation.
Choice B rationale
Urine specific gravity does not identify the risk for pregnancy-induced hypertension. It measures the concentration of urine and can indicate hydration status.
Choice C rationale
Sedimentation rate does not check for signs of cancer. It measures inflammation in the body and can indicate various conditions.
Choice D rationale
Platelet count identifies if the client is at risk for bleeding. Low platelet levels can indicate a higher risk of bleeding and are important to monitor during pregnancy.

Correct Answer is A
Explanation
Choice A rationale
Placing the retainer clip at the level of the baby’s armpits is the correct position for the clip. This ensures that the harness straps are positioned correctly over the baby’s shoulders, providing optimal protection in the event of a crash.
Choice B rationale
Placing the baby in the car seat at a 90-degree angle is incorrect. Newborns should be placed in a rear-facing car seat at an angle of approximately 45 degrees to ensure their airway remains open and to provide proper support for their head and neck.
Choice C rationale
Turning the car seat to face forward when the baby weighs 15 pounds is not recommended. Babies should remain in a rear-facing car seat until they reach the maximum weight or height limit specified by the car seat manufacturer, typically around 2 years of age.
Choice D rationale
Placing a thick, soft pad behind the baby’s back is not recommended. Additional padding can interfere with the proper fit of the harness and reduce the effectiveness of the car seat in protecting the baby during a crash.
Correct Answer is D
Explanation
Choice A rationale
Administering oxygen may help with symptoms like headache and weakness, but it does not address the underlying issue of poor circulation and potential shock. Elevating the legs is more effective in improving blood flow to vital organs.
Choice B rationale
Offering an ice pack is not appropriate for the symptoms described. The client is showing signs of shock, and an ice pack would not address the underlying issue.
Choice C rationale
Providing a warm blanket may offer comfort, but it does not address the symptoms of shock. Elevating the legs is a more direct intervention to improve circulation and stabilize the client.
Choice D rationale
Elevating the client’s legs helps improve venous return to the heart, increasing cardiac output and stabilizing blood pressure. This is a critical intervention for a client showing signs of shock.
