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. A nurse is caring for a client who was recently diagnosed with breast cancer. The oncologist uses the TNM staging system to classify this case as T2, N2, M0. The nurse understands that TNM stands for:

• A. Tumor, Necrosis, Metastasis
• B. Tumor, Node Involvement, Mastectomy
• C. Tumor, Node Involvement, Metastasis
• D. Therapy, Necrosis, Metastasis

Correct answer: B

Rationale: The TNM staging system is a classification system for determining the size and extent of cancerous tissue. The TNM system helps providers to identify the most accurate forms of treatment. The T stands for tumor, the N stands for node involvement, and the M stands for metastasis. Choice A, 'Tumor, Necrosis, Metastasis,' is incorrect because it does not include the node involvement component. Choice B, 'Tumor, Node Involvement, Mastectomy,' is incorrect as it erroneously includes the treatment approach 'Mastectomy' instead of 'Metastasis.' Choice D, 'Therapy, Necrosis, Metastasis,' is incorrect because it includes 'Therapy' instead of the correct component 'Node Involvement.'

3. A client with asthma has low-pitched wheezes present on the final half of exhalation. One hour later the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client

• A. Has increased airway obstruction
• B. Has improved airway obstruction
• C. Needs to be suctioned
• D. Exhibits hyperventilation

Correct answer: B

Rationale: The higher pitched a sound is, the more narrow the airway. Therefore, the obstruction has increased or worsened. With no evidence of secretions, there is no support to indicate the need for suctioning. Wheezes changing from low-pitched to high-pitched and extending throughout exhalation suggest a progression in airway constriction, indicating an increase in airway obstruction. Option B is incorrect because the change in wheezes from low to high pitch does not suggest an improvement in airway obstruction. Option C is incorrect as there is no indication of secretions requiring suctioning. Option D is incorrect as hyperventilation is not typically associated with the described change in wheezes.

4. A patient with idiopathic pulmonary arterial hypertension (IPAH) is receiving nifedipine (Procardia). Which assessment would best indicate to the nurse that the patient's condition is improving?

• A. Blood pressure (BP) is less than 140/90 mm Hg.
• B. Patient reports decreased exertional dyspnea
• C. Heart rate is between 60 and 100 beats/minute
• D. Patient's chest x-ray indicates clear lung fields

Correct answer: B

Rationale: The correct answer is for the patient to report decreased exertional dyspnea. In idiopathic pulmonary arterial hypertension (IPAH), exertional dyspnea is a significant symptom indicating disease severity. Improvement in this symptom suggests that the medication, nifedipine, is effective in managing the condition. While nifedipine can affect blood pressure (choice A) and heart rate (choice C), these parameters are not specific indicators for monitoring IPAH improvement. Choice D, clear lung fields on the chest x-ray, does not directly correlate with the effectiveness of therapy for IPAH. Therefore, the most relevant assessment to monitor improvement in a patient with IPAH receiving nifedipine is a decrease in exertional dyspnea.

5. What is a priority problem for a child with severe edema caused by nephrotic syndrome?

• A. Risk for constipation
• B. Risk for skin breakdown
• C. Inability to regulate body temperature
• D. Consuming more calories or nutrients than the body requires

Correct answer: B

Rationale: In nephrotic syndrome, characterized by massive proteinuria, hypoalbuminemia, and edema, a child with severe edema is at high risk for skin breakdown. The priority concern is to prevent skin breakdown by cleaning skin surfaces and ensuring adequate separation with clothing to avoid irritation. The child with nephrotic syndrome is typically anorexic, making consuming more calories or nutrients than necessary not a concern. Risk for constipation and inability to regulate body temperature are not primary issues associated with edema caused by nephrotic syndrome.
