HESI LPN
HESI Focus on Maternity Exam
1. Humans begin life as a single cell that divides repeatedly. This cell is known as a(n):
- A. zygote.
- B. gonadotrope.
- C. embryo.
- D. chromaffin.
Correct answer: A
Rationale: A zygote is the correct answer. It is the initial cell formed when a sperm cell fertilizes an egg cell, marking the beginning of human development. Choice B, gonadotrope, is incorrect as it refers to a type of hormone-secreting cell in the pituitary gland. Choice C, embryo, is incorrect as it is the stage of development after the zygote has implanted into the uterine wall and undergone initial cell divisions. Choice D, chromaffin, is incorrect as it refers to cells found in the adrenal medulla that produce and store catecholamines.
2. What is idiopathic thrombocytopenia purpura?
- A. Highly similar to disseminated intravascular coagulation (DIC).
- B. Caused by the overproduction of platelets.
- C. A bleeding disorder that is characterized by too few platelets.
- D. Treated with immune system-boosting medications.
Correct answer: C
Rationale: Idiopathic thrombocytopenic purpura is a bleeding disorder characterized by a low number of platelets in the blood. This condition is not highly similar to disseminated intravascular coagulation (DIC), which involves abnormal clotting throughout the body (coagulation), leading to depletion of platelets. Choice B is incorrect because idiopathic thrombocytopenic purpura is actually characterized by a decrease in platelet count, not an overproduction. While immune system-boosting medications may be used in some cases, the primary treatment for idiopathic thrombocytopenic purpura focuses on increasing platelet counts or managing symptoms.
3. What is the primary treatment for minimal change nephrotic syndrome?
- A. corticosteroids
- B. antihypertensive agents
- C. long-term diuretics
- D. increased fluids to promote diuresis
Correct answer: A
Rationale: Corticosteroids are the mainstay of treatment for minimal change nephrotic syndrome due to their immunosuppressive effects, which help reduce proteinuria and control the disease progression. Antihypertensive agents are not the primary treatment for this condition and are typically used to manage hypertension that may result from nephrotic syndrome. Long-term diuretics are not indicated in the treatment of minimal change nephrotic syndrome as they do not address the underlying cause. Increasing fluids to promote diuresis is not a recommended treatment for minimal change nephrotic syndrome, as it can exacerbate edema and fluid overload in these patients.
4. During the second week of hospitalization for intravenous antibiotic therapy, a 2-year-old toddler whose family is unable to visit often smiles easily, goes to all the nurses happily, and does not express interest in the parent when the parent does visit. The parent tells the nurse, 'I am pleased about the adjustment but somewhat concerned about my child’s reaction to me.' How should the nurse respond?
- A. The child is repressing feelings for the parent.
- B. Routines have been established, and the child feels safe.
- C. The child has given up fighting and accepts the separation.
- D. Behavior has improved because the child feels better physically.
Correct answer: C
Rationale: The correct answer is C: 'The child has given up fighting and accepts the separation.' This response indicates that the child is emotionally withdrawing due to the separation from the parent during hospitalization. Choice A is incorrect because the child's behavior does not necessarily suggest repressed feelings for the parent. Choice B is incorrect as feeling safe due to established routines does not fully explain the child's behavior. Choice D is incorrect because while feeling better physically may contribute to improved behavior, it does not address the emotional aspect of the child's reaction to the parent.
5. The PN observes a UAP bathing a bedfast client with the bed in the high position. Which action should the PN take?
- A. Remain in the room to supervise the UAP
- B. Determine if the UAP would like assistance
- C. Assume care of the client immediately
- D. Instruct the UAP to lower the bed for safety
Correct answer: D
Rationale: The correct action for the PN to take in this situation is to instruct the UAP to lower the bed for safety. Keeping the bed in the lowest position during care activities is crucial for preventing falls and injuries to both the client and the caregiver. Instructing the UAP to lower the bed addresses the immediate safety concern. Choice A is incorrect because simply supervising the UAP without addressing the unsafe bed height does not ensure the client's safety. Choice B is incorrect as the priority is to address the safety concern rather than offering assistance to the UAP. Choice C is incorrect as assuming care of the client immediately does not address the root issue of the high bed position.
