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 healthcare provider is preparing to administer an injection of Rho (D) immunoglobulin. The provider should understand that the purpose of this injection is to prevent which of the following newborn complications?

• A. Hydrops fetalis
• B. Hypobilirubinemia
• C. Biliary atresia
• D. Transient clotting difficulties

Correct answer: B

Rationale: Rho (D) immunoglobulin is given to Rh-negative individuals to prevent hemolytic disease of the newborn (HDN) caused by Rh incompatibility between the mother and the fetus. If an Rh-negative mother carries an Rh-positive fetus, there is a risk of sensitization during pregnancy or childbirth. Sensitization can lead to the production of antibodies that may attack Rh-positive red blood cells in future pregnancies, potentially causing severe hemolytic disease in the newborn, including complications like hydrops fetalis. Hydrops fetalis is a condition characterized by severe edema and fetal organ enlargement due to severe anemia and heart failure in the fetus.

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 who is 4 hours postpartum following a vaginal delivery is being assessed by a nurse. Which of the following findings should the nurse identify as the priority?

• A. Saturated perineal pad in 30 minutes
• B. Deep tendon reflexes 4+
• C. Fundus at the level of the umbilicus
• D. Approximated edges of episiotomy

Correct answer: A

Rationale: In a client who is 4 hours postpartum, a saturated perineal pad within 30 minutes is a priority finding as it may indicate excessive postpartum bleeding (hemorrhage), which requires immediate intervention to prevent further complications such as hypovolemic shock. Deep tendon reflexes being 4+ is within normal limits postpartum. The fundus at the level of the umbilicus is an expected finding at this time frame, indicating proper involution of the uterus. Approximated edges of an episiotomy suggest proper healing.

5. A client who is 2 hours postpartum following a cesarean birth has a history of thromboembolic disease. Which of the following nursing interventions should be included in the plan of care?

• A. Apply warm, moist heat to the client's lower extremities.
• B. Massage the client's posterior lower legs.
• C. Place pillows under the client's knees when resting in bed.
• D. Have the client ambulate.

Correct answer: D

Rationale: The correct intervention for a client who is 2 hours postpartum following a cesarean birth with a history of thromboembolic disease is to have the client ambulate. Early ambulation is crucial in preventing complications such as deep vein thrombosis in postpartum clients. Applying warm, moist heat, massaging the legs, or placing pillows under the knees do not directly address the risk of thromboembolic disease in this scenario.
