Nursing Elites

1. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

2. When caring for a child with probable appendicitis, the nurse should be alert to recognize which sign or symptom as a manifestation of perforation?

• A. Anorexia
• B. Bradycardia
• C. Sudden relief from pain
• D. Decreased abdominal distention

Correct answer: C

Rationale: When caring for a child with probable appendicitis, sudden relief from pain is a critical sign that could indicate perforation of the appendix. Perforation results in the release of pressure and inflammation, leading to a temporary relief of pain. Anorexia (loss of appetite) and decreased abdominal distention are symptoms commonly associated with appendicitis itself, not perforation. Bradycardia (slow heart rate) is not typically a direct manifestation of appendicitis or its complications.

3. The nurse is caring for a child with acute postinfectious glomerulonephritis. Which of the following best describes the pathophysiology of acute postinfectious glomerulonephritis?

• A. Occurs after a urinary tract infection
• B. Occurs after a streptococcal infection
• C. Associated with renal vascular disorders
• D. Is caused by E. coli

Correct answer: B

Rationale: The correct answer is B: 'Occurs after a streptococcal infection.' Acute postinfectious glomerulonephritis often occurs after an infection with certain strains of streptococcus bacteria, specifically group A streptococcus. The body’s immune response to the infection leads to inflammation and damage in the kidneys. Choices A, C, and D are incorrect because acute postinfectious glomerulonephritis is primarily associated with streptococcal infections, not urinary tract infections, renal vascular disorders, or E. coli.

4. The parents of a 4-month-old infant tell the nurse that they are getting a microwave oven and will be able to heat the baby’s formula faster. What should the nurse recommend?

• A. Heat only 8 oz or more.
• B. Do not heat a plastic bottle in a microwave oven.
• C. Leave the bottle top uncovered to allow heat to escape.
• D. Shake the bottle vigorously for at least 30 seconds after heating.

Correct answer: B

Rationale: Heating formula in a plastic bottle in the microwave can cause uneven heating and release harmful chemicals from the plastic.

5. The nurse is caring for a very low-birth-weight (VLBW) infant with a peripheral intravenous infusion. What nursing considerations regarding infiltration should be included in planning IV care?

• A. Infiltration is not solely related to the activity level of VLBW infants.
• B. Continuous infusion pumps do not always stop automatically when infiltration occurs.
• C. Hypertonic solutions can cause severe tissue damage if infiltration occurs.
• D. The infusion site should be checked regularly to prevent infiltration-related complications.

Correct answer: C

Rationale: Hypertonic solutions can damage tissues if they leak from the vein due to infiltration. It is crucial to monitor for this complication to prevent severe tissue damage. Infiltration is not solely related to the activity level of VLBW infants; it can occur due to various reasons such as vein condition, catheter placement, and fluid type. Continuous infusion pumps may not always detect infiltration, as they typically alarm for pressure changes but not all infiltration instances. Checking the infusion site regularly, preferably hourly, is essential to prevent complications like tissue damage from extravasations, fluid overload, and dehydration.
