Maternity HESI Practice Questions
1. How many pairs of autosomes does a human zygote contain?
- A. 46
- B. 44
- C. 23
- D. 22
Correct answer: D
Rationale: A human zygote contains 22 pairs of autosomes and one pair of sex chromosomes, totaling 46 chromosomes. Therefore, the correct answer is 22. Choices A, B, and C are incorrect because they do not accurately represent the number of autosomes in a human zygote. Option A (46) represents the total number of chromosomes in a human zygote, not the number of autosomes. Option B (44) is incorrect as it does not account for the correct number of autosomes. Option C (23) is inaccurate since it represents the total number of chromosomes in a human gamete, not the number of autosomes in a zygote.
2. How should a healthcare professional manage a child with scabies?
- A. Use topical permethrin cream
- B. Administer oral antibiotics
- C. Apply topical antifungals
- D. Provide supportive care only
Correct answer: A
Rationale: Corrected Rationale: Topical permethrin cream is the appropriate treatment for scabies as it effectively kills the mites causing the infestation. Oral antibiotics are not indicated for scabies as it is not a bacterial infection. Topical antifungals are used to treat fungal infections, not scabies. Providing supportive care only would not address the underlying cause of scabies, which is the mite infestation.
3. A client who has had an allogeneic stem cell transplant needs protective measures. What precaution should the nurse plan for this client?
- A. Ensure the client wears a mask when outside the room if there is construction nearby.
- B. Place the client in a private room with positive pressure airflow.
- C. Restrict all visitors from seeing the client.
- D. Provide a HEPA filter in the client's room.
Correct answer: A
Rationale: For a client who has undergone an allogeneic stem cell transplant, it is crucial to minimize exposure to potential sources of infection. Wearing a mask when outside the room, especially in areas with construction or other potential risks, helps protect the client's compromised immune system. Positive pressure airflow rooms are typically used for clients with airborne infections, not for those post-stem cell transplant. Restricting all visitors may contribute to the client's well-being, but it is not a direct protective measure against infection. While HEPA filters can be beneficial in maintaining air quality, wearing a mask when exposed to external risks is a more targeted and immediate protective measure in this scenario.
4. A 3-year-old child is admitted to the hospital with a diagnosis of Kawasaki disease. What is the priority nursing intervention?
- A. Administering IV immunoglobulin
- B. Monitoring for coronary artery aneurysms
- C. Encouraging fluid intake
- D. Providing nutritional support
Correct answer: B
Rationale: The priority nursing intervention for a 3-year-old child with Kawasaki disease is monitoring for coronary artery aneurysms. Kawasaki disease can lead to the development of coronary artery aneurysms, which are one of the most serious complications of the disease. Early detection and monitoring of coronary artery changes are essential for prompt intervention and prevention of adverse outcomes. Administering IV immunoglobulin is an important treatment for Kawasaki disease, but monitoring for coronary artery aneurysms takes precedence as it directly impacts the child's long-term prognosis. Encouraging fluid intake and providing nutritional support are important aspects of care but are not the priority when compared to monitoring for potential life-threatening complications.
5. A 2-year-old boy with short bowel syndrome has progressed to receiving enteral feedings only. Today his stools are occurring more frequently and have a more liquid consistency. His temperature is 102.2 °F, and he has vomited twice in the past four hours. Which assessment finding indicates that the child is becoming dehydrated?
- A. Occult blood in the stool
- B. Abdominal distention
- C. Elevated urine specific gravity
- D. Hyperactive bowel sounds
Correct answer: C
Rationale: Elevated urine specific gravity indicates concentrated urine, a sign of dehydration. In this scenario, the child is showing signs of dehydration with increased stool frequency, liquid consistency, fever, and vomiting. Occult blood in the stool may indicate gastrointestinal bleeding but is not a specific sign of dehydration. Abdominal distention can be seen in various conditions and is not a specific indicator of dehydration. Hyperactive bowel sounds can be present in various gastrointestinal conditions but are not directly related to dehydration.
