Nursing Elites

1. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt

Correct answer: B

Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.

2. A 16-year-old female student with a history of asthma controlled with both an oral antihistamine and an albuterol (Proventil) metered-dose inhaler (MDI) comes to the school nurse. The student complains that she cannot sleep at night, feels shaky and her heart feels like it is 'beating a mile a minute.' Which information is most important for the nurse to obtain?

• A. When she last took the antihistamine.
• B. When her last asthma attack occurred.
• C. Duration of most asthma attacks.
• D. How often the MDI is used daily.

Correct answer: D

Rationale: The most important information for the nurse to obtain in this scenario is how often the MDI is used daily. This is crucial to assess if the symptoms the student is experiencing, such as insomnia, shakiness, and tachycardia, could be related to overuse of the inhaler. Overuse of albuterol can lead to side effects like tremors, palpitations, and difficulty sleeping, so understanding the frequency of MDI use is key in determining a potential cause for the student's symptoms. Options A, B, and C are not as pertinent in this situation as they do not directly address the possible link between the student's symptoms and the use of the albuterol MDI.

3. A child receives a prescription for amantadine 42 mg PO BID. Amantadine is available as a 50 mg/5 mL syrup. Using a supplied calibrated measuring device, how many mL should be administered per dose? (Round to the nearest tenth.)

• A. 4.2 mL
• B. 5 mL
• C. 3.6 mL
• D. 4 mL

Correct answer: A

Rationale: To calculate the mL per dose, divide the prescribed dose (42 mg) by the concentration of the syrup (50 mg/5 mL) and then convert the result to mL. 42 mg / 50 mg = 0.84. To find the amount in mL, multiply 0.84 by 5 mL, which equals 4.2 mL. Therefore, 4.2 mL should be administered per dose.

4. The mother of a 14-year old who had a below-the-knee amputation for osteosarcoma tells the nurse that her child is angry and blaming her for allowing the amputation to occur. Which response is best for the nurse to provide?

• A. I will ask the HCP for a psychiatric consult for your child'
• B. This type of acting out behavior is normal for adolescents'
• C. It is important to focus on your child’s needs at this difficult time'
• D. A reaction of anger is your child’s attempt to cope with this loss'

Correct answer: D

Rationale: Acknowledging the child's anger as part of the coping process helps the mother understand her child's emotional response.

5. While assessing the vital signs of a 10-year-old who underwent a tonsillectomy this morning, the nurse observes the child swallowing every 2-3 minutes. Which assessment should the nurse implement?

• A. Inspect the posterior oropharynx
• B. Assess for teeth clenching or grinding
• C. Touch the tonsillar pillars to stimulate the gag reflex
• D. Ask the child to speak to evaluate a change in voice tone

Correct answer: A

Rationale: Frequent swallowing post-tonsillectomy may indicate bleeding. Inspecting the posterior oropharynx is essential to assess for any signs of bleeding, such as fresh blood or clots, which may necessitate immediate intervention. Option B is incorrect as teeth clenching or grinding is not directly related to the observation of frequent swallowing in this scenario. Option C is incorrect because stimulating the gag reflex is not necessary at this point and may be uncomfortable for the child. Option D is incorrect as evaluating a change in voice tone is not relevant to the situation of observing frequent swallowing.
