Nursing Elites

1. 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.

2. A client with chronic kidney disease has arterial blood gas values being reviewed by a nurse. Which of the following sets of values should the nurse expect?

• A. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
• B. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg
• C. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg
• D. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg

Correct answer: A

Rationale: In chronic kidney disease, metabolic acidosis is common due to impaired kidney function leading to reduced bicarbonate excretion. The correct values indicating metabolic acidosis in this scenario are a low pH (acidosis), low bicarbonate (HCO3-) level, and low PaCO2 (compensation through respiratory alkalosis). Therefore, the expected values for a client with chronic kidney disease would be pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg, as depicted in choice A.

3. A healthcare provider is caring for a group of clients on an intrapartum unit. Which of the following findings should be reported to the provider immediately?

• A. A tearful client who is at 32 weeks of gestation and is experiencing irregular, frequent contractions
• B. A client who is at 28 weeks of gestation and receiving terbutaline reports fine tremors
• C. A client who has a diagnosis of preeclampsia has 2+ proteinuria and 2+ patellar reflexes
• D. A client who has a diagnosis of preeclampsia reports epigastric pain and an unresolved headache

Correct answer: D

Rationale: The correct answer is a client who has a diagnosis of preeclampsia reporting epigastric pain and an unresolved headache. These symptoms indicate severe preeclampsia, which requires immediate medical attention due to the potential risks of complications such as HELLP syndrome or eclampsia. The other options describe concerning situations but do not represent immediate life-threatening conditions like those seen in severe preeclampsia.

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 healthcare professional is reviewing the arterial blood gas results for a client in the ICU who has kidney failure and determines the client has respiratory acidosis. Which of the following findings should the healthcare professional expect?

• A. Widened QRS complexes
• B. Hyperactive deep tendon reflexes
• C. Bounding peripheral pulses
• D. Warm, flushed skin

Correct answer: A

Rationale: Respiratory acidosis is characterized by an increase in carbon dioxide levels in the blood, leading to acidosis. This condition can affect the heart's electrical conduction system, resulting in widened QRS complexes on an electrocardiogram (ECG). Hyperactive deep tendon reflexes, bounding peripheral pulses, and warm, flushed skin are not typically associated with respiratory acidosis.
