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. 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.

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 at 37 weeks of gestation with placenta previa asks the nurse why the provider does not do an internal examination. Which of the following explanations of the primary reason should the nurse provide?

• A. There is an increased risk of introducing infection.
• B. This could initiate preterm labor.
• C. This could result in profound bleeding.
• D. There is an increased risk of rupture of the membranes.

Correct answer: C

Rationale: Performing an internal examination in a client with placenta previa can lead to significant bleeding due to the proximity of the placenta to the cervical os. This bleeding can be severe and potentially life-threatening. Therefore, it is crucial to avoid any unnecessary manipulation that could disrupt the delicate balance and lead to hemorrhage.

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.
