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 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. During the admission assessment of a client at 38 weeks of gestation with severe preeclampsia, what would the nurse expect as a finding?

• A. Tachycardia
• B. Absence of clonus
• C. Polyuria
• D. Report of headache

Correct answer: D

Rationale: Severe preeclampsia is characterized by hypertension and proteinuria after 20 weeks of gestation. Headache is a common symptom in clients with severe preeclampsia due to cerebral edema or vasospasm. Tachycardia (Choice A) is not typically associated with severe preeclampsia. Clonus (Choice B) is a sign of hyperactive reflexes, often seen in clients with severe preeclampsia. Polyuria (Choice C) is not a typical finding in clients with severe preeclampsia.

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 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.
