RN exams pediatrics practice questions

Correct answer:

Comparing the patient's present weight with her last weight is the best way to quickly assess volume depletion in Miss CC. As she has been experiencing frequent diarrhea leading to blood and fluid loss, changes in weight are a reliable indicator of changes in the body's fluid status. A significant decrease in weight would suggest a loss of fluid and potential hypovolemia due to the diarrhea. This method is simple, immediate, and directly reflects the impact of the fluid loss on the body's volume status. Measuring the quantity and specific gravity of her urine output could provide information on her kidney function but may not be as quick and direct in evaluating volume depletion as comparing her current weight with her last recorded weight. Taking her blood pressure is important in assessing overall cardiovascular status but may not be as immediate in reflecting the impact of fluid loss on volume status. Administering the oral water test is not a standard method for quickly assessing volume depletion in this scenario.

Correct answer:

By assessing the patient's swallowing reflex, the nurse can determine if the patient is able to swallow food and liquids properly, which is crucial for adequate nutrition intake. Bell's Palsy can affect facial muscles, including those involved in chewing and swallowing. A impaired swallowing reflex can lead to difficulties in eating and drinking, which in turn may affect the patient's nutrition status. Monitoring meal trays (A) may not provide direct information about the patient's ability to swallow, as a patient may not be able to communicate swallowing difficulties. Checking twice-weekly weights (B) may indicate weight changes, but it may not necessarily give insight into nutrition adequacy related to swallowing ability. Measuring intake and output (C) may help track calorie intake and fluid balance, but it may not specifically address swallowing issues that can impact nutrition in a patient with Bell's Palsy. Assessing the swallowing reflex (D) directly addresses the patient's ability to consume food and

Correct answer:

Referring children with sore throats for throat cultures is important in the prevention of rheumatic fever. Rheumatic fever is a complication of untreated streptococcal throat infections, specifically caused by group A Streptococcus bacteria. By identifying and treating streptococcal infections promptly with antibiotics, the risk of developing rheumatic fever is significantly reduced. The school nurse plays a crucial role in recognizing the symptoms of strep throat and ensuring that affected children are appropriately referred for testing and treatment. This can help prevent the serious consequences of rheumatic fever, which can affect the heart, joints, skin, and brain if left untreated. Encouraging routine cholesterol screenings (choice A) and blood pressure screenings (choice B) are important for overall health monitoring but are not directly related to the prevention of rheumatic fever. Recommending salicylates over acetaminophen (choice D) is not advisable in children due to the risk of Reye's syndrome

Correct answer:

Providing a solution of hydrogen peroxide and water for use as a mouth rinse is most likely to decrease the pain of stomatitis. Stomatitis is inflammation of the oral mucous membranes and can be quite painful for oncology clients undergoing chemotherapy. Using a solution of hydrogen peroxide and water as a mouth rinse can help reduce the risk of infection and promote healing of the mucous membranes, thereby decreasing the pain associated with stomatitis. This intervention helps to maintain oral hygiene and prevent further complications, making it an effective way to manage the client's symptoms while undergoing chemotherapy. It is important to note that discontinuing chemotherapy would not be a recommended intervention as it is the primary treatment for the client's cancer. Monitoring platelet and leukocyte counts and checking for signs and symptoms of stomatitis are important aspects of care, but providing a mouth rinse would directly address the pain and discomfort experienced by the client.

Correct answer:

It is important to instruct the client's family to check with the physician or pharmacist before crushing or breaking tablets, or opening capsules for a client with impaired swallowing who needs to take solid medication. Many medications have special formulations or coating that may alter their effectiveness if not taken whole. Consulting with a healthcare professional ensures that the medication remains safe and effective when modifying its form for a client with difficulty swallowing. Mixing the medication with food (option A) may also alter its effectiveness, so it is crucial to seek guidance before making any changes to the medication form. Using the liquid form of the medication (option B) may be a suitable alternative if available; however, this decision should also be discussed and approved by the healthcare provider. Performing ROM exercises after medication administration (option D) is unrelated to addressing the issue of impaired swallowing and medication administration.

Correct answer:

Vestibulospinal tract . The corticospinal tract decussatin the medullary pyramids, with most fibers crossing to form the lateral corticospinal tract for contralateral voluntary movement. The corticonuclear tract also decussates, though partially, as fibers from the cortex to cranial nerve nuclei (e.g., 7, 12) cross to innervate contralateral lower facial musclor tongue, evident in facial palsy from stroke. The tectospinal tract decussatin the midbrain, originating from the superior colliculus to coordinate head movements toward stimuli (e.g., visual reflexes). However, the vestibulospinal tract donot decussate; it descends ipsilaterally from the vestibular nuclei in the brainstem to spinal motor neurons, facilitating posture and balance (e.g., antigravity muscles). This ipsilateral nature is critical, as unilateral vestibular lesions cause same-side extensor tone changes, unlike crossed tracts. Thus, D is the exception among these descending tracts, making it the correct answer.

Correct answer:

A 6-hour glucose tolerance test would yield the most occlusive diagnostic information about the client's glucose utilization in this case. The elevated blood pressure level of 185 mg/dL two hours after breakfast indicates poor glucose regulation. A glucose tolerance test involves monitoring the client's blood glucose levels over a period of time after ingesting a glucose solution. This test provides a comprehensive assessment of how the body processes glucose, revealing any abnormalities in glucose metabolism beyond fasting levels, such as postprandial (after-meal) glucose spikes and prolonged hyperglycemia. This can help identify conditions like insulin resistance, impaired glucose tolerance, or diabetes, which may not be evident from a fasting blood glucose test alone. Glycosylated hemoglobin (HbA1c) reflects average blood sugar levels over the past 2-3 months and would not provide immediate information about the client's current glucose metabolism. Urine ketones

Correct answer:

Controls voluntary movements of the musclof the face, head, and neck . The corticonuclear tract originatfrom the motor cortex, specifically the precentral gyrus (not cerebellum, making A incorrect), and descends through the internal capsule to terminate in brainstem cranial nerve nuclei (not spinal cord, making D wrong). It donot decussate completely in the midbrain (B is false); instead, its fibers partially cross at various brainstem levels, with some (e.g., cranial nerve 7 lower face) contralateral and others (e.g., 11) bilateral. Choice C is true; it controls voluntary movements of musclin the face (e.g., smiling via cranial nerve 7), head (e.g., tongue via 12), and neck (e.g., sternocleidomastoid via 11), via nuclei of cranial nerv5, 7, 9, 10, 11, and 12. For example, a cortical lesion causcontralateral lower facial weakness, demonstrating its role in voluntary control. Thus, C accurately describthe corticonuclear tracts function, making it the correct answer.

Correct answer:

When setting up supplies for a client who requires a blood transfusion, the appropriate nursing intervention is to prime the tubing of the blood administration set with 0.9% NS solution completely, filling the filter. This is essential to ensure that the blood components flow smoothly through the tubing and any potential air bubbles are removed in order to prevent air embolism and ensure the safety of the blood transfusion process. Option A is not correct because adding IV medication in the blood bag is not a standard practice and can compromise the integrity of the blood product. Option B is also incorrect as blood products should be stored and maintained at specific temperatures to prevent spoilage or contamination; leaving it at room temperature is not advised. Option D is unrelated to setting up supplies for a blood transfusion and addresses inadequate dietary intake, which is a different nursing concern than the preparation of blood transfusion supplies.

Correct answer:

Diabetic ketoacidosis (DKA) is a potentially life-threatening complication of diabetes characterized by hyperglycemia, ketosis, and metabolic acidosis. The initial treatment for DKA requires correcting dehydration and electrolyte imbalances. Normal saline infusion is the preferred choice for initial fluid resuscitation in patients with DKA to address dehydration and restore intravascular volume. It helps improve organ perfusion and correct electrolyte imbalances such as hyponatremia and dehydration commonly seen in DKA patients. Administering normal saline helps replace lost fluids and improve circulation, which is crucial in the management of DKA. Potassium infusion may be needed later to replete potassium levels once the patient's kidney function has been assessed. NPH insulin infusion is not the initial treatment for DKA, although insulin therapy is an essential component of DKA management. 5% dextrose infusion is contraindicated in the initial treatment
