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 acute respiratory failure (ARF) may present with which of the following manifestations? (Select one that doesn't apply.)

• A. Severe dyspnea
• B. Decreased level of consciousness
• C. Headache
• D. Nausea

Correct answer: D

Rationale: In acute respiratory failure (ARF), the body is not getting enough oxygen, leading to respiratory distress. Symptoms of ARF typically include severe dyspnea (difficulty breathing), decreased level of consciousness due to hypoxia, and headache from inadequate oxygenation to the brain. Nausea is not a typical manifestation of ARF and would not be expected in this condition.

3. A nurse in the antepartum unit is caring for a client who is at 36 weeks of gestation and has pregnancy-induced hypertension. Suddenly, the client reports continuous abdominal pain and vaginal bleeding. The nurse should suspect which of the following comp

• A. Placenta previa
• B. Prolapsed cord
• C. Incompetent cervix
• D. Abruptio placentae

Correct answer: D

Rationale:

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 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.
