A nurse is preparing to collect a specimen for newborn screening.
Which of the following actions should the nurse take?
Warm the newborn’s heel for 5 to 10 minutes before the puncture.
Use a lancet to puncture the inner aspect of the newborn’s heel.
Leave the newborn’s heel open to the air after the puncture.
Apply an antiseptic to the newborn’s heel after collecting the specimen.
The Correct Answer is A
Choice A rationale
Warming the newborn’s heel for 5 to 10 minutes before the puncture increases blood flow, making it easier to collect a blood sample.
Choice B rationale
The outer aspect of the heel is the recommended site for puncture to avoid injury to the bone and nerves.
Choice C rationale
Leaving the heel open to the air after the puncture is not recommended as it can increase the risk of infection.
Choice D rationale
Applying an antiseptic after collecting the specimen is not necessary and can interfere with the blood sample.

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.
Correct Answer is A
Explanation
Choice A rationale
Eating dry, bland foods in the morning can help alleviate nausea by providing a gentle start to the digestive system. Bland foods like crackers or toast are less likely to irritate the stomach lining and can help absorb stomach acids, reducing the feeling of nausea.
Choice B rationale
Taking an over-the-counter antacid is not recommended for nausea during pregnancy unless prescribed by a healthcare provider. Antacids are typically used to neutralize stomach acid and relieve heartburn, not nausea.
Choice C rationale
Restricting fluids to 1,000 mL/day is not advisable as it can lead to dehydration. Adequate hydration is essential during pregnancy to support the increased blood volume and amniotic fluid.
Choice D rationale
Increasing the intake of fresh fruits is beneficial for overall health but may not specifically address nausea. Some fruits can be acidic and might worsen nausea in some individuals.
