Nursing Elites

1. 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.

2. 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.

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 client in a prenatal clinic is being taught by a nurse in her second trimester with a new diagnosis of gestational diabetes. Which of the following client statements indicates a need for further teaching?

• A. I should limit my carbohydrates to 50% of caloric intake.
• B. I will reduce my exercise schedule to 3 days a week.
• C. I will take my glyburide daily with breakfast.
• D. I know I am at increased risk of developing type 2 diabetes.

Correct answer: B

Rationale: Choice B, 'I will reduce my exercise schedule to 3 days a week,' indicates a need for further teaching. Regular exercise is beneficial in managing gestational diabetes and should not be reduced without proper guidance. Choices A, C, and D demonstrate understanding and appropriate actions in managing gestational diabetes.

5. A nurse in an antepartum unit is triaging clients. Which of the following clients should the nurse see first?

• A. A client who is at 38 weeks of gestation and reports a cough and fever
• B. A client who has missed a period and reports vaginal spotting
• C. A client who is at 14 weeks of gestation and reports nausea and vomiting
• D. A client who is at 28 weeks of gestation and reports of painless vaginal bleeding

Correct answer: D
