Nursing Elites

1. A healthcare professional is reviewing the laboratory values of a client who has respiratory acidosis. Which of the following findings should the healthcare professional expect?

• A. HCO3- 30 mEq/L
• B. PaCO2 50 mm Hg
• C. pH 7.45
• D. Potassium 3.3 mEq/L

Correct answer: B

Rationale: In respiratory acidosis, the primary disturbance is an increase in PaCO2 levels above the normal range of 35-45 mm Hg. Option B, PaCO2 50 mm Hg, indicates an elevated partial pressure of carbon dioxide, which is consistent with respiratory acidosis. Options A, C, and D are not directly indicative of respiratory acidosis. HCO3- (Option A) is more related to metabolic acidosis or alkalosis, pH (Option C) is within the normal range indicating no acid-base imbalance, and potassium (Option D) levels are not specific to respiratory acidosis.

2. A client who was admitted to the maternity unit at 38 weeks of gestation and who is experiencing polyhydramnios is found to have which of the following?

• A. The client is carrying more than one fetus
• B. There is an elevated level of alpha-fetoprotein (AFP) in the amniotic fluid
• C. An excessive amount of amniotic fluid is present
• D. The fetus is likely to have a congenital anomaly, be growth restricted, or demonstrate fetal distress during labor

Correct answer: C

Rationale: Polyhydramnios refers to the presence of an excessive amount of amniotic fluid around the fetus. This condition can result from various causes, such as maternal diabetes, fetal anomalies, or genetic disorders. It can lead to complications during pregnancy and delivery, such as preterm labor, placental abruption, or fetal malpresentation. Understanding this diagnosis is crucial for providing appropriate care and monitoring to ensure the best outcomes for both the mother and the fetus.

3. 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.

4. 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.

5. A client in labor at 40 weeks of gestation has saturated two perineal pads in the past 30 min. The nurse suspects placenta previa. Which of the following is an appropriate nursing action?

• A. Examination to determine cervical status
• B. A magnesium sulfate infusion
• C. Initiation of pushing
• D. Preparation for cesarean birth

Correct answer: D

Rationale: In the scenario described, the client is experiencing heavy vaginal bleeding, which is concerning for placenta previa. The appropriate nursing action in this situation is to prepare for a cesarean birth. Placenta previa is a condition where the placenta partially or completely covers the cervix, which can lead to life-threatening bleeding during labor. It is crucial to avoid vaginal examinations or initiation of pushing as these actions can exacerbate bleeding. A magnesium sulfate infusion is not indicated in the management of placenta previa. Therefore, the priority intervention is to prepare for a cesarean birth to ensure the safety of the mother and the baby.
