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 at 22 weeks of gestation with uncontrolled gestational diabetes mellitus may require medication. Which of the following medications would the provider likely prescribe?

• A. Acarbose
• B. Repaglinide
• C. Glyburide
• D. Glipizide

Correct answer: C

Rationale: Glyburide is commonly prescribed for gestational diabetes mellitus when diet and exercise are insufficient to control blood sugar levels. It is considered safe and effective during pregnancy, making it a suitable choice for managing diabetes in pregnant individuals. Acarbose, Repaglinide, and Glipizide are not typically recommended for use in pregnancy due to potential risks to the fetus.

3. A client is receiving positive-pressure mechanical ventilation. Which of the following interventions should the nurse implement to prevent complications? (Select one that doesn't apply.)

• A. Elevate the head of the bed to at least 30�.
• B. Apply restraints if the client becomes agitated.
• C. Administer pantoprazole as prescribed.
• D. Reposition the endotracheal tube to the opposite side of the mouth daily.

Correct answer: D

Rationale: Repositioning the endotracheal tube to the opposite side of the mouth daily is not a standard practice in preventing complications in a client receiving positive-pressure mechanical ventilation. This action may disrupt the secure placement of the endotracheal tube and increase the risk of complications. Elevating the head of the bed to at least 30� helps prevent aspiration and ventilator-associated pneumonia. Applying restraints if the client becomes agitated helps maintain the safety of the client by preventing self-extubation or accidental dislodgement of tubes. Administering pantoprazole as prescribed helps prevent stress ulcers, a common complication in critically ill patients on mechanical ventilation.

4. 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.

5. 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.
