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 coarctation 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 findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

2. A two-year-old child with heart failure is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?

• A. Determine the pulse deficit.
• B. Administer the scheduled dose.
• C. Calculate the safe dose range.
• D. Review the serum digoxin level.

Correct answer: B

Rationale: Administering the scheduled dose is appropriate in this scenario as the heart rate of 128 bpm falls within the acceptable range for a two-year-old child with heart failure. It indicates that the child may benefit from the therapeutic effects of digoxin. Monitoring the heart rate closely after administration is essential to ensure the medication's effectiveness and safety. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is within the acceptable range. Calculating the safe dose range (Choice C) is not needed since the heart rate is already within the expected parameters. Reviewing the serum digoxin level (Choice D) is not the immediate action required in this case where the heart rate is within the normal range.

3. The nurse provides information about the human papillomavirus (HPV) vaccine to the mother of a 14-year-old adolescent who came to the clinic this morning complaining of menstrual cramping. Which explanation should the nurse provide to support administering the HPV vaccine to the adolescent at this visit?

• A. Use of protective barriers during sexual activity prevents most strains of HPV infection
• B. Most adolescents are not honest about being sexually active
• C. Not all strains of HPV will be covered if given at a later date
• D. Immunity must be established to prevent future HPV infection and the risk for cervical cancer

Correct answer: D

Rationale: Administering the HPV vaccine helps establish immunity before potential exposure to the virus, reducing the risk of HPV infection and subsequent development of cervical cancer. It is recommended to vaccinate adolescents before they become sexually active for maximum effectiveness. Choice A is incorrect because while protective barriers can reduce the risk, they do not prevent all strains of HPV. Choice B is incorrect and judgmental as it assumes dishonesty without providing relevant information about HPV vaccination. Choice C is incorrect as it downplays the importance of vaccination by suggesting that not all strains are necessary to cover, which is not the case in preventing HPV-related diseases.

4. A 10-year-old child with hemophilia is admitted to the hospital with joint pain and swelling. What should the healthcare provider do first?

• A. Apply ice to the affected joint
• B. Administer pain medication
• C. Elevate the affected limb
• D. Administer factor VIII as prescribed

Correct answer: D

Rationale: Administering factor VIII as prescribed is the priority intervention for a child with hemophilia experiencing joint pain and swelling. Hemophilia is a genetic disorder that impairs the blood's ability to clot properly, leading to prolonged bleeding. Factor VIII replacement therapy is essential as it helps restore the missing clotting factor in patients with hemophilia, thereby aiding in clot formation and preventing further bleeding. Applying ice, administering pain medication, or elevating the limb may be supportive measures but addressing the underlying cause by providing factor VIII therapy takes precedence in managing hemophilia-related joint pain and swelling.

5. The healthcare provider is evaluating the effects of thyroid therapy used to treat a 5-month-old with hypothyroidism. Which behavior indicates that the treatment has been effective?

• A. Laughs readily, turns from back to side.
• B. Has strong Moro and tonic neck reflexes.
• C. Keeps fists clenched, opens hands when grasping an object.
• D. Can lift head but not chest when lying on abdomen.

Correct answer: A

Rationale: In infants, laughing readily and turning from back to side are developmental milestones that indicate effective thyroid therapy and normal development. These actions demonstrate improved muscle tone, coordination, and overall growth, which are key indicators of successful treatment for hypothyroidism in infants. Choices B, C, and D describe behaviors that are not specific indicators of thyroid therapy effectiveness in treating hypothyroidism in infants.
