Nursing Elites

1. A child weighing 30 kg arrives at the clinic with diffuse itching as the result of an allergic reaction to an insect bite. Diphenhydramine (Benadryl) 25 mg 3 times a day is prescribed. The correct pediatric dose is 5 mg/kg/day. Which of the following best describes the prescribed drug dose?

• A. It is the correct dose
• B. The dose is too low
• C. The dose is too high
• D. The dose should be increased or decreased, depending on the symptoms

Correct answer: The dose is too low

Rationale: The correct pediatric dose of diphenhydramine is 5 mg/kg/day. This child weighs 30 kg, so the calculated dose would be 5 mg/kg x 30 kg = 150 mg/day. Since the prescription is for 25 mg 3 times a day, the total daily dose is 25 mg x 3 = 75 mg/day, which is lower than the calculated dose of 150 mg/day. Therefore, the prescribed dose of 25 mg 3 times a day is too low for this child. The dose should be adjusted to meet the correct dosage of 150 mg/day, which would be 50 mg 3 times a day. It is important not to titrate the dosage based on symptoms without consulting a physician, as this can lead to inappropriate medication administration.

2. A patient with a possible pulmonary embolism complains of chest pain and difficulty breathing. The nurse finds a heart rate of 142 beats/minute, blood pressure of 100/60 mmHg, and respirations of 42 breaths/minute. Which action should the nurse take first?

• A. Administer anticoagulant drug therapy.
• B. Notify the patient's healthcare provider.
• C. Prepare the patient for a spiral computed tomography (CT).
• D. Elevate the head of the bed to a semi-Fowler's position.

Correct answer: Elevate the head of the bed to a semi-Fowler's position.

Rationale: The patient presents with symptoms indicative of a pulmonary embolism (PE), such as chest pain, difficulty breathing, tachycardia, hypotension, and tachypnea. Elevating the head of the bed to a semi-Fowler's position is the priority to improve ventilation and gas exchange. This intervention should be initiated promptly to optimize oxygenation. Subsequent actions, such as notifying the healthcare provider, preparing for a spiral CT scan, and administering anticoagulant therapy, can follow after the patient's position is adjusted. The spiral CT scan is typically used to confirm the diagnosis of PE, and anticoagulant therapy is initiated upon confirmation of the diagnosis by the healthcare provider. Therefore, the immediate focus is on improving the patient's respiratory status by elevating the head of the bed.

3. When assessing a patient suspected to have Hepatitis, a nurse notes the patient's eyes are yellow-tinged. Which of the following diagnostic results would further assist in confirming this diagnosis?

• A. Decreased serum Bilirubin
• B. Elevated serum ALT levels
• C. Low RBC and Hemoglobin with increased WBCs
• D. Increased Blood Urea Nitrogen level

Correct answer: Elevated serum ALT levels

Rationale: Elevated serum ALT levels would further confirm the diagnosis of Hepatitis. ALT is a liver enzyme, and hepatitis is a liver disease. Elevated liver enzymes, such as ALT, often indicate liver damage. Choice A, 'Decreased serum Bilirubin,' is incorrect as elevated bilirubin levels are typically seen in hepatitis due to impaired bilirubin metabolism. Choices C and D are unrelated to confirming a diagnosis of hepatitis as they describe findings not specific to liver function or hepatitis. Low RBC and Hemoglobin with increased WBCs (Choice C) suggest a different condition like anemia or infection, not specific to liver disease. Increased Blood Urea Nitrogen level (Choice D) is more indicative of kidney function rather than liver function, thus not helpful in confirming hepatitis.

4. When reading a lab report, you notice that a patient's sample is described as having anisocytosis. Which of the following most accurately describes the patient's condition?

• A. The patient has an abnormal condition of skin cells.
• B. The patient's red blood cells vary in size.
• C. The patient has a high level of fat cells and is obese.
• D. The patient's cells are indicative of necrosis.

Correct answer: The patient's red blood cells vary in size.

Rationale: Anisocytosis is a term that indicates variation in the size of red blood cells. When a patient is described as having anisocytosis, it means their red blood cells exhibit differences in size. This condition can be detected in blood samples and may indicate underlying blood disorders. The other choices are incorrect: Choice A refers to a skin cell condition, Choice C relates to obesity and fat cells, and Choice D suggests necrosis, none of which are associated with anisocytosis or red blood cell abnormalities. It is important to recognize specific terms like anisocytosis in laboratory reports to understand the potential implications for the patient's health.

5. The child with hemolytic-uremic syndrome is anuric and will undergo peritoneal dialysis. Which measure should the nurse implement?

• A. Restrict fluids as prescribed.
• B. Care for the arteriovenous fistula.
• C. Encourage foods high in potassium.
• D. Administer analgesics as prescribed.

Correct answer: Restrict fluids as prescribed.

Rationale: In hemolytic-uremic syndrome, often associated with bacterial toxins and viruses, acute kidney injury occurs in children, leading to symptoms like anemia, thrombocytopenia, renal injury, and CNS symptoms. For an anuric child with hemolytic-uremic syndrome undergoing peritoneal dialysis, fluid restriction is vital to prevent fluid overload. Pain management is not directly related to hemolytic-uremic syndrome. Foods high in potassium should be limited, not encouraged, due to impaired kidney function. Peritoneal dialysis does not involve an arteriovenous fistula, which is specific to hemodialysis.
