Maternity HESI Practice Questions
1. A premature infant with respiratory distress syndrome (RDS) receives artificial surfactant. How does the nurse explain surfactant therapy to the parents?
- A. “Surfactant improves the ability of your baby’s lungs to exchange oxygen and carbon dioxide.”
- B. “The drug keeps your baby from requiring too much sedation.”
- C. “Surfactant is used to reduce episodes of periodic apnea.”
- D. “Your baby needs this medication to fight a possible respiratory tract infection.”
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.
2. When reviewing EBP about the administration of O2 therapy, what is the recommended maximum flow rate for regulating O2 via nasal cannula?
- A. Regulate O2 via nasal cannula no more than 6L
- B. Regulate O2 via nasal cannula no more than 2L
- C. Regulate O2 via nasal cannula no more than 4L
- D. Regulate O2 via nasal cannula no more than 8L
Correct answer: A
Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.
3. A client enters the emergency department unconscious via ambulance from the client's workplace. What document should be given priority to guide the direction of care for this client?
- A. The statement of client rights and the client self-determination act
- B. Orders written by the healthcare provider
- C. A notarized original copy of advance directives brought in by the partner
- D. The clinical pathway protocol of the agency and the emergency department
Correct answer: C
Rationale: In the scenario described, when a client arrives unconscious, priority should be given to a notarized original copy of advance directives brought in by the partner. Advance directives are legal documents that specify a person's healthcare wishes and decision-making preferences in advance. These directives guide healthcare providers in delivering care according to the client's preferences when the client is unable to communicate. The statement of client rights and the client self-determination act (Choice A) are important but do not provide specific care instructions. Orders written by the healthcare provider (Choice B) may not reflect the client's wishes. Clinical pathway protocols (Choice D) are valuable but do not address the individualized care preferences of the client.
4. An infant is diagnosed with Hirschsprung disease. What nursing intervention is essential before surgery?
- A. Administering antibiotics
- B. Ensuring bowel rest
- C. Performing regular enemas
- D. Maintaining NPO status
Correct answer: D
Rationale: The correct nursing intervention essential before surgery for an infant with Hirschsprung disease is maintaining NPO (nothing by mouth) status. This is important to prevent aspiration during and after the surgical procedure. Administering antibiotics (Choice A) may be necessary in some cases but is not the priority intervention before surgery. Ensuring bowel rest (Choice B) is not directly related to preparing for surgery and may not be the most critical intervention. Performing regular enemas (Choice C) is not recommended before surgery for Hirschsprung disease as it can aggravate the condition.
5. A client with diabetes mellitus presents with confusion and diaphoresis. What is the priority nursing action?
- A. Check the blood glucose level
- B. Administer insulin immediately
- C. Offer a high-protein snack
- D. Place the client in a supine position
Correct answer: A
Rationale: The correct answer is to check the blood glucose level. In a client with diabetes mellitus presenting with confusion and diaphoresis, it is important to assess the blood glucose level first to determine if the symptoms are due to hypoglycemia. Administering insulin immediately (Choice B) without knowing the blood glucose level can worsen the condition if the client is hypoglycemic. Offering a high-protein snack (Choice C) is not appropriate as the severity of hypoglycemia is unknown, and placing the client in a supine position (Choice D) is not the priority action for these symptoms.
