A postpartum nurse instructs a new mother in how to bathe her newborn.

Which statement by the mother indicates a need for further instruction?

“I should use a clean cloth and warm water to wash around the umbilical cord.”

“I should bathe him before a feeding so he won’t spit up.”

“I should avoid getting water in his ears or eyes.”

Answer and Explanation

The Correct Answer is B

The correct answer is choice B. “I should bathe him before a feeding so he won’t spit up.” This statement indicates a need for further instruction because it is not advisable to bathe a newborn infant before a feeding, as this may cause hypoglycemia or cold stress. The mother should bathe the infant after a feeding or between feedings when the infant is alert and comfortable.

Choice A is wrong because it is correct to use a clean cloth and warm water to wash around the umbilical cord. This helps prevent infection and promotes drying of the cord stump.

Choice C is wrong because it is correct to avoid getting water in the infant’s ears or eyes. This helps prevent ear infections and eye irritation.

Choice D is wrong because it is correct to dry the infant thoroughly and dress him warmly after bathing.

This helps prevent heat loss

Correct Answer is A

Explanation

The correct answer is choice A. Bulging fontanelle.

A bulging fontanelle is a sign of increased intracranial pressure, which can be caused by intracranial hemorrhage.

Late-onset VKDB is a condition that occurs in infants who have low levels of vitamin K, which is essential for blood clotting.Most cases of late-onset VKDB present with intracranial hemorrhage.

Choice B. Sunken eyes is wrong because it is a sign of dehydration, not intracranial hemorrhage.

Choice C. Mottled skin is wrong because it is a sign of poor circulation or shock, not intracranial hemorrhage.

Choice D. Flaring nostrils is wrong because it is a sign of respiratory distress, not intracranial hemorrhage.

Normal ranges for vitamin K plasma concentrations are 0.2 to 3.2 ng/mL for adults and 0.15 to 1.5 ng/mL for infants.

A. Factor II B. Factor V C. Factor VIII D. Factor XI

Correct Answer is A

Explanation

The correct answer is choice A.Factor II, also known as prothrombin, is one of the coagulation factors that are activated by vitamin K.Vitamin K is a cofactor for the carboxylation of specific glutamic acid groups in coagulation factors II, VII, IX, and X.

This process is essential for the activation of these factors in the coagulation cascade.

Choice B is wrong because factor V is not a vitamin K-dependent coagulation factor.

Factor V is activated by thrombin and acts as a cofactor for factor Xa in the conversion of prothrombin to thrombin.

Choice C is wrong because factor VIII is not a vitamin K-dependent coagulation factor.

Factor VIII is activated by thrombin and acts as a cofactor for factor IXa in the activation of factor X.

Choice D is wrong because factor XI is not a vitamin K-dependent coagulation factor.

Factor XI is activated by factor XIIa and activates factor IX in the intrinsic pathway of coagulation.

Normal ranges for coagulation factors are:

• Factor II: 70-120% of normal activity

• Factor V: 50-150% of normal activity

• Factor VIII: 50-150% of normal activity

• Factor IX: 50-150% of normal activity

• Factor X: 70-140% of normal activity

• Factor XI: 70-150% of normal activity
