A nurse in a prenatal clinic is determining a client's estimated date of delivery using Naegele's rule.
The first day of her last menstrual period was April 4, 2023.
Which of the following dates should the nurse tell the client is her estimated date of delivery (EDD)?

Choice A rationale:

The purpose of administering vitamin K to a newborn is to prevent bleeding. Vitamin K plays a crucial role in blood clotting. Newborns often have lower levels of vitamin K, which can make them more susceptible to bleeding disorders, such as hemorrhagic disease of the newborn (HDN). HDN can lead to serious bleeding complications, including intracranial hemorrhage, which can be life-threatening.

Choice B rationale:

Hyperbilirubinemia is not the primary purpose of administering vitamin K. While vitamin K can indirectly help in preventing jaundice (hyperbilirubinemia) by reducing the risk of bleeding that may lead to hemolysis, it is not the primary aim of vitamin K administration.

Choice C rationale:

Potassium deficiency (hypokalemia) is not a primary concern related to vitamin K administration. Vitamin K is specifically administered to prevent bleeding disorders and not to address potassium levels.

Choice D rationale:

Infection is not related to the administration of vitamin K. Vitamin K is not used to prevent or treat infections in newborns; its primary role is in blood clotting.

Choice A rationale:

The client is experiencing symptoms that suggest hyperventilation due to paced breathing, which can lead to respiratory alkalosis. Breathing into a paper bag or cupped hand allows the client to rebreathe carbon dioxide and helps correct the alkalosis by increasing the carbon dioxide levels in the blood. This is a common intervention for clients experiencing lightheadedness and tingling in the fingers due to hyperventilation.

Choice B rationale:

Instructing the client to maintain a breathing rate no less than twice the normal rate is not appropriate in this situation. It can worsen the client's symptoms and may lead to further hyperventilation. This choice does not address the underlying problem of respiratory alkalosis.

Choice C rationale:

Having the client tuck her chin to her chest is not the correct action for these symptoms. This maneuver is typically used to relieve supraventricular tachycardia (SVT) or vagal stimulation in situations of rapid heart rate. It is not relevant to the client's lightheadedness and tingling fingers.

Choice D rationale:

Administering oxygen via nasal cannula is not indicated in this case. The client's symptoms are not suggestive of hypoxemia, but rather, they are related to respiratory alkalosis. Providing oxygen could potentially worsen the condition by reducing carbon dioxide levels further.
