Nursing Elites

1. Clinical manifestations of sodium excess (hypernatremia) include which signs or symptoms?

• A. Hyperreflexia
• B. Abdominal cramps
• C. Cardiac dysrhythmias
• D. Dry, sticky mucous membranes

Correct answer: D

Rationale: Hypernatremia often presents with dry, sticky mucous membranes due to dehydration. Hyperreflexia and abdominal cramps may also occur, but dry mucous membranes are more consistently observed in cases of sodium excess.

2. What is the most common cause of acute gastroenteritis in children under 5 years?

• A. Salmonella
• B. Rotavirus
• C. Norovirus
• D. Shigella

Correct answer: B

Rationale: Rotavirus is the leading cause of acute gastroenteritis in children under 5 years. It leads to severe diarrhea and dehydration. Vaccination against rotavirus has significantly reduced the incidence of this disease, but it remains a major cause of morbidity in young children globally. Salmonella and Shigella can cause gastroenteritis, but they are less common in children under 5 years. Norovirus is also a common cause of gastroenteritis, but Rotavirus is the most prevalent in this age group.

3. The nurse is providing education to the parent of a child with Beta-thalassemia. Which risk factors about the condition should the nurse include in the teaching?

• A. Hypertrophy of the thyroid
• B. Polycythemia vera
• C. Thrombocytopenia
• D. Chronic hypoxia and iron overload

Correct answer: D

Rationale: The correct answer is D: Chronic hypoxia and iron overload. Children with Beta-thalassemia often suffer from chronic hypoxia due to ineffective erythropoiesis and require frequent blood transfusions, leading to iron overload. These complications must be managed to prevent organ damage. Choices A, B, and C are incorrect. Hypertrophy of the thyroid, polycythemia vera, and thrombocytopenia are not direct risk factors associated with Beta-thalassemia. Therefore, they should not be included in the teaching regarding this condition.

4. Parents of a child who will need hemodialysis ask the nurse, What are the advantages of a fistula over a graft or external access device for hemodialysis? (Select all that apply.)

• A. It is ready to be used immediately.
• B. All below
• C. There is less restriction of activity with a fistula.
• D. It produces dilation and thickening of the superficial vessels.

Correct answer: A

Rationale: A fistula typically has fewer complications, allows for greater freedom of movement, and involves natural vessel changes that improve dialysis efficiency. However, it is not ready for immediate use, which is why it may take weeks to mature before it can be used.

5. During examination of a toddler's extremities, the nurse notes that the child is bowlegged. The nurse should recognize that this finding is which?

• A. Abnormal and requires further investigation
• B. Abnormal unless it occurs in conjunction with knock-knee
• C. Normal if the condition is unilateral or asymmetric
• D. Normal because the lower back and leg muscles are not yet well developed

Correct answer: D

Rationale: Bowleggedness is normal in toddlers due to the development of lower back and leg muscles. It usually resolves as the child grows.
