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: B

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. The nursing care plan for a toddler diagnosed with Kawasaki Disease (mucocutaneous lymph node syndrome) should be based on the high risk for development of which problem?

• A. Chronic vessel plaque formation
• B. Pulmonary embolism
• C. Occlusions at the vessel bifurcations
• D. Coronary artery aneurysms

Correct answer: A

Rationale: The correct answer is chronic vessel plaque formation. Kawasaki Disease affects small and medium-sized blood vessels, leading to progressive inflammation and potential damage to the walls of medium-sized muscular arteries, which can result in coronary artery aneurysms. While other complications such as pulmonary embolism and occlusions at vessel bifurcations can occur in different conditions, for Kawasaki Disease, the primary concern is the development of chronic vessel plaque formation.

3. Based on the information given, which patient would be an appropriate candidate for a closed MRI without contrast?

• A. A 20-year-old woman with unexplained joint pain and a low BMI.
• B. A 35-year-old woman with Multiple Sclerosis who is trying to conceive.
• C. A 67-year-old man who had open-heart surgery 4 years ago.
• D. A 40-year-old woman in a hypomanic state for the last 2 days.

Correct answer: A

Rationale: The correct answer is the 20-year-old woman with unexplained joint pain and a low BMI. MRI can be used to diagnose musculoskeletal disorders, and this patient has no contraindications to an MRI. Choice B is incorrect because using MRI without contrast may not be ideal for a patient trying to conceive. Choice C is incorrect as the patient's past open-heart surgery may pose risks for an MRI without contrast. Choice D is incorrect since the patient's hypomanic state does not indicate a need for an MRI without contrast for joint pain.

4. A female patient is prescribed metformin for glucose control. The patient is on NPO status pending a diagnostic test. The nurse is most concerned about which side effect of metformin?

• A. Diarrhea and Vomiting
• B. Dizziness and Drowsiness
• C. Metallic taste
• D. Hypoglycemia

Correct answer: D

Rationale: The correct answer is 'Hypoglycemia.' When a patient is on NPO status (nothing by mouth) and prescribed metformin, there is an increased risk of hypoglycemia due to the absence of oral intake. Metformin, as an anti-glycemic drug, can lower blood sugar levels, and without food intake, the risk of hypoglycemia is higher. Diarrhea and vomiting are common gastrointestinal side effects of metformin but are not the main concern in this scenario. Dizziness and drowsiness are potential side effects of some medications but are not typically associated with metformin. Metallic taste is a known side effect of metformin but is not the primary concern in this situation where hypoglycemia is more critical to monitor due to the patient's NPO status.

5. The infant has a diagnosis of bladder exstrophy. To protect the exposed bladder tissue, what intervention should the nurse plan?

• A. Cover the bladder with petroleum jelly gauze.
• B. Cover the bladder with a non-adhering plastic wrap.
• C. Apply sterile distilled water dressings over the bladder mucosa.
• D. Keep the bladder tissue dry by covering it with dry sterile gauze.

Correct answer: C

Rationale: Bladder exstrophy is a condition where the bladder is exposed and external to the body. To protect the exposed bladder tissue from drying out while allowing urine drainage, it is best to cover the bladder with a non-adhering plastic wrap. Using petroleum jelly gauze should be avoided as it can dry out, adhere to the mucosa, and damage delicate tissue upon removal. Applying sterile distilled water dressings can also dry out and cause damage when removed. Keeping the bladder tissue dry with sterile gauze is not ideal as maintaining a moist environment is important for tissue protection in this case.
