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. The healthcare provider is caring for a 3-year-old child who is hospitalized with dehydration. The child is now receiving IV fluids and has started to produce urine. What is the best indicator that the child’s dehydration is improving?

• A. The child’s urine output has increased
• B. The child’s skin turgor is normal
• C. The child’s weight has increased
• D. The child’s vital signs are stable

Correct answer: A

Rationale: An increase in urine output is a reliable indicator that the child's hydration status is improving. Adequate urine output signifies that the kidneys are functioning properly and that the body is effectively eliminating waste and excess fluids, indicating improved hydration levels. The other options are not as direct indicators of hydration status. Skin turgor and weight changes can be influenced by various factors, and stable vital signs do not specifically reflect hydration status.

3. How should the caregiver instruct on caring for a 4-month-old with seborrheic dermatitis (cradle cap) when shampooing the child's hair?

• A. Use a soft brush and gently scrub the area.
• B. Avoid scrubbing the scalp until the scales disappear.
• C. Avoid washing the child's hair more than once a week.
• D. Use soap and water and avoid shampoos.

Correct answer: A

Rationale: When dealing with seborrheic dermatitis (cradle cap) in infants, it is essential to use a soft brush and gently scrub the affected area to help remove the scales. This process can aid in managing the condition and preventing further build-up. It is important to be gentle to avoid irritating the baby's delicate skin. Choice B is incorrect as gentle scrubbing with a soft brush can help in the removal of scales. Choice C is incorrect because regular but gentle washing is recommended to manage cradle cap. Choice D is incorrect as using specialized shampoos designed for cradle cap is usually recommended over soap and water.

4. The healthcare provider is providing postoperative care to a 4-year-old child who underwent tonsillectomy. The provider notices that the child is frequently swallowing. What should the provider do first?

• A. Check the child’s throat for signs of bleeding
• B. Offer the child ice chips to soothe the throat
• C. Elevate the head of the child’s bed
• D. Administer prescribed pain medication

Correct answer: A

Rationale: Frequent swallowing after tonsillectomy may indicate bleeding, which requires immediate assessment and intervention. Checking the child’s throat for signs of bleeding is the priority to ensure timely identification and management of any potential bleeding complications.

5. A school-age child with a history of type 1 diabetes mellitus is brought to the emergency department with confusion and rapid breathing. The practical nurse (PN) suspects diabetic ketoacidosis (DKA). Which initial intervention should the PN anticipate?

• A. Administer subcutaneous insulin.
• B. Give oral glucose tablets.
• C. Start intravenous fluids.
• D. Administer oxygen therapy.

Correct answer: C

Rationale: Intravenous fluids are typically the initial intervention in diabetic ketoacidosis (DKA) to treat dehydration and stabilize the patient's condition. The fluid replacement helps correct electrolyte imbalances and improve perfusion, which are crucial in managing DKA. Insulin therapy follows after fluid resuscitation to address the underlying cause of DKA, which is the lack of insulin leading to increased ketone production. Administering subcutaneous insulin (Choice A) would be premature without first addressing the dehydration and electrolyte imbalances. Giving oral glucose tablets (Choice B) is contraindicated in DKA as the patient already has high blood glucose levels. Administering oxygen therapy (Choice D) may be necessary based on the patient's condition, but addressing dehydration with intravenous fluids is the priority intervention in DKA.
