Nursing Elites

1. When reviewing the arterial blood gas values for a client, a nurse notes a pH of 7.32, PaCO2 of 48 mm Hg, and HCO3 of 23 mEq/L. What does this indicate about the acid-base balance?

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

Correct answer: A

Rationale: The given values suggest respiratory acidosis. In respiratory acidosis, the pH is low (<7.35), PaCO2 is high (>45 mm Hg), and the HCO3 is normal or slightly elevated. In this scenario, the low pH (7.32) and high PaCO2 (48 mm Hg) indicate respiratory acidosis, where there is an excess of carbon dioxide in the blood, leading to acidification of the body fluids.

2. A nurse in the antepartum unit is caring for a client who is at 36 weeks of gestation and has pregnancy-induced hypertension. Suddenly, the client reports continuous abdominal pain and vaginal bleeding. The nurse should suspect which of the following comp

• A. Placenta previa
• B. Prolapsed cord
• C. Incompetent cervix
• D. Abruptio placentae

Correct answer: D

Rationale:

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 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.

5. A client at 22 weeks of gestation with uncontrolled gestational diabetes mellitus may require medication. Which of the following medications would the provider likely prescribe?

• A. Acarbose
• B. Repaglinide
• C. Glyburide
• D. Glipizide

Correct answer: C

Rationale: Glyburide is commonly prescribed for gestational diabetes mellitus when diet and exercise are insufficient to control blood sugar levels. It is considered safe and effective during pregnancy, making it a suitable choice for managing diabetes in pregnant individuals. Acarbose, Repaglinide, and Glipizide are not typically recommended for use in pregnancy due to potential risks to the fetus.
