Nursing Elites

1. A newborn is born to a mother with poorly controlled type 2 diabetes. The newborn is macrosomic and presents with respiratory distress syndrome. The most likely cause of the respiratory distress is which of the following?

• A. Hyperinsulinemia
• B. Increased deposits of fat in the chest and shoulder area
• C. Brachial plexus injury
• D. Increased blood viscosity

Correct answer: A

Rationale: The correct answer is hyperinsulinemia. In infants born to mothers with poorly controlled diabetes, the excess glucose crosses the placenta, leading to fetal hyperglycemia. This results in fetal hyperinsulinemia, which in turn can cause macrosomia (large birth weight), increasing the risk of respiratory distress syndrome due to the immature lungs' inability to handle the increased workload. Hyperinsulinemia, not increased deposits of fat, brachial plexus injury, or increased blood viscosity, is the most likely cause of respiratory distress in this scenario.

2. A client is admitted to the emergency room with a respiratory rate of 7/min. Arterial blood gases (ABG) reveal the following values. Which of the following is an appropriate analysis of the ABGs? pH 7.22, PaCO2 68 mm Hg, Base excess -2, PaO2 78 mm Hg, Saturation 80%, Bicarbonate 26 mEq/L

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

Correct answer: A

Rationale: The ABG values provided indicate respiratory acidosis. In respiratory acidosis, there is an increase in PaCO2 above the normal range (35-45 mm Hg) leading to a decrease in pH (<7.35). In this case, the pH is 7.22 (below normal) with an elevated PaCO2 of 68 mm Hg. The other values do not suggest metabolic acidosis (which would typically show low bicarbonate levels) or metabolic alkalosis. Therefore, the correct interpretation of the ABGs is respiratory acidosis.

3. A healthcare professional is reviewing the arterial blood gas results for a client in the ICU who has kidney failure and determines the client has respiratory acidosis. Which of the following findings should the healthcare professional expect?

• A. Widened QRS complexes
• B. Hyperactive deep tendon reflexes
• C. Bounding peripheral pulses
• D. Warm, flushed skin

Correct answer: A

Rationale: Respiratory acidosis is characterized by an increase in carbon dioxide levels in the blood, leading to acidosis. This condition can affect the heart's electrical conduction system, resulting in widened QRS complexes on an electrocardiogram (ECG). Hyperactive deep tendon reflexes, bounding peripheral pulses, and warm, flushed skin are not typically associated with respiratory acidosis.

4. A nurse receives report about assigned clients at the start of the shift. Which of the following clients should the nurse plan to see first?

• A. A client who experienced a cesarean birth 4 hours ago and reports pain
• B. A client who has preeclampsia with a BP of 138/90 mm Hg
• C. A client who experienced a vaginal birth 24 hours ago and reports no bleeding
• D. A client who is scheduled for discharge following a laparoscopic tubal ligation

Correct answer: A

Rationale: The nurse should prioritize seeing the client who experienced a cesarean birth 4 hours ago and reports pain first. Pain assessment and management are crucial post-cesarean birth to ensure the client's comfort and well-being. Immediate attention is needed to address the client's pain and provide appropriate interventions. The other clients may require attention but do not have an immediate postoperative concern like pain following a cesarean birth.

5. A client with chronic kidney disease has arterial blood gas values being reviewed by a nurse. Which of the following sets of values should the nurse expect?

• A. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
• B. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg
• C. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg
• D. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg

Correct answer: A

Rationale: In chronic kidney disease, metabolic acidosis is common due to impaired kidney function leading to reduced bicarbonate excretion. The correct values indicating metabolic acidosis in this scenario are a low pH (acidosis), low bicarbonate (HCO3-) level, and low PaCO2 (compensation through respiratory alkalosis). Therefore, the expected values for a client with chronic kidney disease would be pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg, as depicted in choice A.
