HESI Maternity 55 Questions

1. A nurse on an antepartum unit is reviewing the medical records for four clients. Which of the following clients should the nurse assess first?

Correct answer: C

Rationale: A sodium level of 110 mEq/L is critically low and can indicate severe dehydration and electrolyte imbalance, requiring immediate intervention.

2. Does a blastocyst gain mass only when it receives nourishment from outside?

Correct answer: A

Rationale: A blastocyst does indeed require external nourishment from the mother's body to continue developing and gaining mass. Without this external nourishment, the blastocyst would not be able to grow and develop properly. Therefore, the statement that a blastocyst gains mass only when it receives nourishment from outside is true. Choices B, C, and D are incorrect because they do not accurately reflect the dependency of a blastocyst on external nourishment for its development and growth.

3. A premature infant with respiratory distress syndrome (RDS) receives artificial surfactant. How does the nurse explain surfactant therapy to the parents?

Correct answer: A

Rationale: Artificial surfactant can be administered as an adjunct to oxygen and ventilation therapy for premature infants with respiratory distress syndrome (RDS). It helps improve respiratory compliance by aiding in the exchange of oxygen and carbon dioxide until the infant can produce enough surfactant naturally. The correct explanation to the parents would be that surfactant therapy enhances the baby’s lung function by facilitating the exchange of oxygen and carbon dioxide. Choice B is incorrect because surfactant therapy does not affect sedation needs. Choice C is inaccurate as surfactant is not used to reduce episodes of periodic apnea. Choice D is incorrect as surfactant is not administered to fight respiratory tract infections; it specifically targets improving lung function in RDS.

4. How many chromosomes are typically found in human cells, organized into pairs?

Correct answer: B

Rationale: Human cells typically contain 46 chromosomes organized into 23 pairs. This is the correct number for a normal human cell. Choices A, C, and D are incorrect because they do not represent the typical chromosome count in human cells.

5. When caring for a pregnant woman with cardiac problems, the nurse must be alert for the signs and symptoms of cardiac decompensation. Which critical findings would the nurse find on assessment of the client experiencing this condition?

Correct answer: D

Rationale: In pregnant women with cardiac problems, signs of cardiac decompensation include dyspnea, crackles, an irregular, weak, and rapid pulse, rapid respirations, a moist and frequent cough, generalized edema, increasing fatigue, and cyanosis of the lips and nailbeds. Choice A is incorrect as a regular heart rate and hypertension are not typically associated with cardiac decompensation. Choice B is incorrect as increased urinary output and dry cough are not indicative of cardiac decompensation, only tachycardia is. Choice C is incorrect as bradycardia and hypertension are not typically seen in cardiac decompensation; dyspnea is a critical sign instead.
