1. The parents of a child with sickle cell anemia ask why their child experiences pain. What is the most likely cause?
- A. Inflammation of the vessels
- B. Obstructed blood flow
- C. Overhydration
- D. Stress-related headaches
Correct answer: B
Rationale: In sickle cell anemia, pain is primarily caused by the obstruction of blood flow by sickle-shaped cells. This obstruction leads to inadequate oxygen supply to tissues, resulting in tissue damage and pain. Choice A, inflammation of the vessels, is incorrect as it is not the primary cause of pain in sickle cell anemia. Choice C, overhydration, is unrelated to the pathophysiology of sickle cell anemia and would not lead to the characteristic pain experienced. Choice D, stress-related headaches, is also unrelated to the underlying mechanisms of pain in sickle cell anemia.
2. What is the typical therapeutic management treatment for children with Hirschsprung disease?
- A. Daily enemas
- B. Low-fiber diet
- C. Permanent colostomy
- D. Surgical removal of affected section of bowel
Correct answer: D
Rationale: The most common treatment for Hirschsprung disease is the surgical removal of the affected section of the bowel. This procedure entails excising the part of the colon that lacks nerve cells crucial for normal bowel function. Daily enemas (Choice A) can offer temporary relief for constipation but do not address the root cause of the condition, which is the absence of nerve cells. A low-fiber diet (Choice B) is not a primary therapy for Hirschsprung disease and may not effectively manage the disorder. A permanent colostomy (Choice C) is typically considered in severe cases where other interventions have failed and is not the standard management approach for Hirschsprung disease.
3. A home health nurse is planning to provide health promotion activities for a group of clients in the community. Which of the following activities is an example of the nurse promoting primary prevention?
- A. Educating clients about the recommended immunization schedule for adults
- B. Teaching clients how to manage chronic illnesses
- C. Providing counseling for depression
- D. Offering support groups for cancer survivors
Correct answer: A
Rationale: The correct answer is A: Educating clients about the recommended immunization schedule for adults. This activity falls under primary prevention, which aims to prevent the onset of illness or injury. Immunizations are a proactive measure to protect individuals from developing certain diseases. Choices B, C, and D involve managing chronic illnesses, providing counseling for mental health issues, and offering support for individuals who have already experienced cancer, respectively. These activities are more aligned with secondary or tertiary prevention, focusing on managing existing conditions or preventing complications in those already affected.
4. Which characteristic is most typical of a chronic disease?
- A. It has a rapid onset.
- B. It rarely has noticeable symptoms.
- C. It produces sharp pains.
- D. It progresses gradually.
Correct answer: D
Rationale: The correct answer is D. Chronic diseases are characterized by a gradual progression over time, affecting individuals for an extended period. Option A is incorrect as chronic diseases do not have a rapid onset like acute conditions. Option B is incorrect as chronic diseases often manifest noticeable symptoms. Option C is incorrect as sharp pains are not a defining characteristic of chronic diseases. Chronic diseases can present a variety of symptoms depending on the specific condition, but gradual progression is a common feature distinguishing them from acute illnesses.
5. A nurse in a pediatric unit is preparing to administer medication to a child. What should the nurse do to ensure the correct dosage?
- A. Check the child's weight
- B. Verify the medication order with a pharmacist
- C. Consult the child's parents
- D. Double-check the dosage calculations with another nurse
Correct answer: D
Rationale: When administering medication to children, it is crucial to ensure the correct dosage to prevent dosing errors. Double-checking the dosage calculations with another nurse can help verify the accuracy of the prescribed dose, reducing the risk of medication errors. While checking the child's weight (Choice A) is important for dosage calculation, it alone may not ensure the correctness of the dosage. Verifying the medication order with a pharmacist (Choice B) is essential, but it may not directly address the accuracy of dosage calculations. Consulting the child's parents (Choice C) is not a standard practice for verifying medication dosages and should not be solely relied upon for ensuring the correct dosage.
