Nursing Elites

1. A client with severe preeclampsia is receiving magnesium sulfate IV at 2 g/hr. Which of the following findings indicates that it is safe to continue the infusion?

• A. Diminished deep-tendon reflexes
• B. Respiratory rate of 16/min
• C. Urine output of 50 mL in 4 hours
• D. Heart rate of 56/min

Correct answer: B

Rationale: A respiratory rate of 16/min within the normal range is an essential parameter to monitor when administering magnesium sulfate, as respiratory depression is a potential adverse effect. Diminished deep-tendon reflexes may indicate magnesium toxicity, warranting immediate intervention. A urine output of 50 mL in 4 hours is below the expected amount, suggesting decreased kidney perfusion, which can be exacerbated by magnesium sulfate. A heart rate of 56/min is bradycardic and may indicate magnesium toxicity, requiring assessment and possible discontinuation of the infusion.

2. A client who experienced a cesarean birth due to dysfunctional labor expresses disappointment for not having a natural childbirth. Which response should the nurse make?

• A. Validate the client's feelings by saying, 'It sounds like you are feeling sad that things didn't go as planned.'
• B. Assure the client by stating, 'At least you know you have a healthy baby.'
• C. Encourage the client by suggesting, 'Maybe next time you can have a vaginal delivery.'
• D. Provide information by saying, 'You can resume sexual relations sooner than if you had delivered vaginally.'

Correct answer: A

Rationale: The correct response is to acknowledge and validate the client's feelings of disappointment. This empathetic approach demonstrates understanding and support for the client's emotional state, fostering a therapeutic nurse-client relationship. Options B, C, and D do not address the client's emotional needs or provide appropriate support in this situation.

3. 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.

4. 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.

5. 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.
