Nursing Elites

1. A client at 37 weeks of gestation with placenta previa asks the nurse why the provider does not do an internal examination. Which of the following explanations of the primary reason should the nurse provide?

• A. There is an increased risk of introducing infection.
• B. This could initiate preterm labor.
• C. This could result in profound bleeding.
• D. There is an increased risk of rupture of the membranes.

Correct answer: C

Rationale: Performing an internal examination in a client with placenta previa can lead to significant bleeding due to the proximity of the placenta to the cervical os. This bleeding can be severe and potentially life-threatening. Therefore, it is crucial to avoid any unnecessary manipulation that could disrupt the delicate balance and lead to hemorrhage.

2. 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.

3. A client is receiving positive-pressure mechanical ventilation. Which of the following interventions should the nurse implement to prevent complications? (Select one that doesn't apply.)

• A. Elevate the head of the bed to at least 30�.
• B. Apply restraints if the client becomes agitated.
• C. Administer pantoprazole as prescribed.
• D. Reposition the endotracheal tube to the opposite side of the mouth daily.

Correct answer: D

Rationale: Repositioning the endotracheal tube to the opposite side of the mouth daily is not a standard practice in preventing complications in a client receiving positive-pressure mechanical ventilation. This action may disrupt the secure placement of the endotracheal tube and increase the risk of complications. Elevating the head of the bed to at least 30� helps prevent aspiration and ventilator-associated pneumonia. Applying restraints if the client becomes agitated helps maintain the safety of the client by preventing self-extubation or accidental dislodgement of tubes. Administering pantoprazole as prescribed helps prevent stress ulcers, a common complication in critically ill patients on mechanical ventilation.

4. A client with preterm labor is being admitted. The nurse anticipates a prescription by the provider for which of the following medications?

• A. Prostaglandin E2
• B. Indomethacin
• C. Methylergonovine
• D. Oxytocin

Correct answer: B

Rationale: Indomethacin is used to delay premature labor by inhibiting uterine contractions. Prostaglandin E2, Methylergonovine, and Oxytocin are not typically used to manage preterm labor. Prostaglandin E2 can be used for cervical ripening and labor induction. Methylergonovine is used to prevent or control postpartum hemorrhage. Oxytocin is used for labor induction and augmentation of labor in term pregnancies.

5. 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.
