Essential of Pediatric Nursing Test Bank Questions
Question 1 of 5
A woman sees her primary care provider because of extreme fatigue for the past 2 months; she difficulty lifting even light objects. Her physician suspects myasthenia gravis. Which of the ff. tests should the nurse anticipate to confirm this diagnosis?
Correct Answer: D
Rationale: The Tensilon test is used to confirm the diagnosis of myasthenia gravis, a condition characterized by muscle weakness and fatigue. In this test, the medication Tensilon (also known as edrophonium) is administered intravenously. If the patient has myasthenia gravis, there will be a rapid but temporary improvement in muscle strength after the Tensilon injection. This response helps to differentiate myasthenia gravis from other causes of muscle weakness. The other options mentioned (Mestinon test, pulmonary function studies, and quinine tolerance test) do not specifically confirm the diagnosis of myasthenia gravis.
Question 2 of 5
Which of the following is MOST likely considered a risk factor for extraneural metastasis in primary brain tumors?
Correct Answer: A
Rationale: Younger age is a significant risk factor for extraneural metastasis in pediatric brain tumors.
Question 3 of 5
The nurse is preparing a client for magnetic resonance imaging (MRI) to confirm or rule out a spinal cord lesion. During the MRI scan, which of the following would pose a threat to the client?
Correct Answer: B
Rationale: The client wearing a watch and wedding band would pose a threat during the MRI scan. MRI machines use strong magnetic fields that can interact with metal objects. The presence of metal objects such as a watch and wedding band can lead to serious safety risks for the client inside the MRI machine. These metal objects can become projectiles or heat up, causing burns or other injuries. Thus, it is crucial for the client to remove all metal objects before undergoing an MRI scan to ensure their safety.
Question 4 of 5
A 3-year-old child from a suburban community presents with vomiting, diarrhea, and blurred vision. Physical examination reveals an afebrile child with pinpoint pupils, salivation, and muscular fasciculations. The child's lawn was treated yesterday for insects. Which of the following tests will establish the correct diagnosis?
Correct Answer: C
Rationale: The symptoms suggest organophosphate poisoning, which can be confirmed by measuring plasma cholinesterase levels, as organophosphates inhibit this enzyme.
Question 5 of 5
Which laboratory results (besides hematuria) are most consistent with hemolytic uremic syndrome (HUS)?
