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 client with acute respiratory failure (ARF) may present with which of the following manifestations? (Select one that doesn't apply.)

• A. Severe dyspnea
• B. Decreased level of consciousness
• C. Headache
• D. Nausea

Correct answer: D

Rationale: In acute respiratory failure (ARF), the body is not getting enough oxygen, leading to respiratory distress. Symptoms of ARF typically include severe dyspnea (difficulty breathing), decreased level of consciousness due to hypoxia, and headache from inadequate oxygenation to the brain. Nausea is not a typical manifestation of ARF and would not be expected in this condition.

4. 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.

5. During an assessment, a nurse is evaluating a pregnant client for preeclampsia. Which of the following findings should indicate to the nurse that the client requires further evaluation for this disorder?

• A. Increased urine output
• B. Vaginal discharge
• C. Elevated blood pressure
• D. Joint pain

Correct answer: C

Rationale: Preeclampsia is characterized by elevated blood pressure, proteinuria, and sometimes edema. Hypertension is a key sign of preeclampsia, and if present, further evaluation and monitoring are necessary to prevent complications for both the mother and the fetus.
