Question 1 of 5
a definitive diagnosis of sickle cell disease is based on which diagnostic result
Correct Answer: D
Rationale: A definitive diagnosis of sickle cell disease is based on hemoglobin electrophoresis. This test separates the different types of hemoglobin based on their electrical charge, allowing for the detection of abnormal hemoglobin variants such as hemoglobin S, which is characteristic of sickle cell disease. A complete blood count (CBC) can show various abnormalities seen in sickle cell disease, but it is not specific for confirming the diagnosis. Bone marrow aspiration is not routinely used for diagnosing sickle cell disease. Blood chemistry tests may reveal some complications associated with sickle cell disease but do not confirm the condition itself. Hemoglobin electrophoresis is the gold standard for diagnosing sickle cell disease by identifying the specific hemoglobin variant characteristic of the disorder.
Question 2 of 5
Which is most important in the immediate care of the newborn?
Correct Answer: A
Rationale: Maintaining a patent airway is the most critical aspect in the immediate care of a newborn. An open airway is essential for the newborn to breathe effectively and receive adequate oxygen. Any obstruction in the airway can lead to respiratory distress and compromise the baby's oxygenation. Therefore, ensuring the airway is clear and the newborn can breathe properly is the top priority in providing immediate care. While other choices are important aspects of newborn care, ensuring a patent airway takes precedence in order to support the newborn's respiratory function and overall well-being.
Question 3 of 5
The nurse is teaching nursing students about childhood skin lesions. Which is an elevated, circumscribed skin lesion that is less than 1 cm in diameter and filled with serous fluid?
Correct Answer: D
Rationale: A vesicle is an elevated, circumscribed skin lesion that is less than 1 cm in diameter and filled with serous fluid. Serous fluid is a clear, watery fluid that can accumulate within the vesicle. Vesicles are commonly seen in conditions such as herpes simplex virus infections (cold sores) and contact dermatitis. It is important for nursing students to understand the characteristics of different skin lesions to accurately assess and provide appropriate care for patients.
Question 4 of 5
Acyclovir (Zovirax) is given to children with chickenpox to:
Correct Answer: B
Rationale: Acyclovir (Zovirax) is an antiviral medication commonly used to treat infections caused by the herpes virus, including chickenpox. When given to children with chickenpox, acyclovir helps decrease the number of lesions present on the skin by slowing down the replication of the virus. This not only helps alleviate the discomfort associated with the rash but also reduces the risk of potential complications and accelerates the healing process. While acyclovir does not completely eliminate the virus from the body, it can help control the symptoms and prevent severe manifestations.
Question 5 of 5
A nurse is preparing to administer an oral iron supplement to a hospitalized infant. Which should not be given simultaneously with the iron supplement?
Correct Answer: A
Rationale: Milk should not be given simultaneously with an oral iron supplement because calcium in milk can interfere with the absorption of iron. Calcium competes with iron for absorption in the digestive tract, thereby reducing the absorption of iron when both are taken together. It is advisable to wait at least 1-2 hours after giving the iron supplement before offering milk to ensure optimal absorption of iron. This is a common practice to improve iron absorption and prevent any potential decrease in the effectiveness of the iron supplement.
