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 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.

3. 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.

4. A client in a prenatal clinic is being taught by a nurse in her second trimester with a new diagnosis of gestational diabetes. Which of the following client statements indicates a need for further teaching?

• A. I should limit my carbohydrates to 50% of caloric intake.
• B. I will reduce my exercise schedule to 3 days a week.
• C. I will take my glyburide daily with breakfast.
• D. I know I am at increased risk of developing type 2 diabetes.

Correct answer: B

Rationale: Choice B, 'I will reduce my exercise schedule to 3 days a week,' indicates a need for further teaching. Regular exercise is beneficial in managing gestational diabetes and should not be reduced without proper guidance. Choices A, C, and D demonstrate understanding and appropriate actions in managing gestational diabetes.

5. When admitting a client at 33 weeks of gestation with a diagnosis of placenta previa, which action should the nurse prioritize?

• A. Monitor vaginal bleeding
• B. Administer glucocorticoids
• C. Insert an IV catheter
• D. Apply an external fetal monitor

Correct answer: D

Rationale: Placenta previa is a condition where the placenta partially or completely covers the cervix, leading to potential bleeding. When admitting a client with placenta previa, the priority is to assess the fetal well-being. Applying an external fetal monitor helps in continuous monitoring of the fetal heart rate and ensures timely detection of any distress or changes in the fetal status, which is crucial in managing this condition. While monitoring vaginal bleeding is important, identifying fetal well-being takes precedence in this situation.
