1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. A nurse assesses a client who has a history of heart failure. Which question should the nurse ask to assess the extent of the client's heart failure?

• A. Do you have trouble breathing or chest pain?
• B. Are you able to walk upstairs without fatigue?
• C. Do you awake with breathlessness during the night?
• D. Do you have new-onset heaviness in your legs?

Correct answer: B

Rationale: Clients with a history of heart failure generally have negative findings, such as shortness of breath. The nurse needs to determine whether the client's activity is the same or worse, or whether the client identifies a decrease in activity level. Trouble breathing, chest pain, breathlessness at night & peripheral edema are symptoms of heart failure, but do not provide data that can determine the extent of the client's heart failure.

3. A healthcare professional is caring for a client who has just developed a pulmonary embolism. Which of the following medications should the healthcare professional anticipate administering?

• A. Furosemide
• B. Dexamethasone
• C. Heparin
• D. Atropine

Correct answer: C

Rationale: In the scenario of a pulmonary embolism, the priority medication to administer is Heparin. Heparin is an anticoagulant that helps prevent the formation of new blood clots and the growth of existing ones, which is crucial in managing pulmonary embolism. Furosemide is a diuretic used to treat fluid retention, Dexamethasone is a corticosteroid used for inflammation, and Atropine is an anticholinergic medication used for various purposes such as treating bradycardia.

4. After an open lung biopsy, a nurse assesses a client. Which assessment finding is matched with the correct intervention?

• A. Client states he is dizzy. Nurse applies oxygen and pulse oximetry.
• B. Client's HR is 55 beats/min. Nurse withholds pain medication.
• C. Client has reduced breath sounds. Nurse calls the physician immediately.
• D. Client's RR is 18 breaths/min. Nurse decreases the oxygen flow rate.

Correct answer: C

Rationale: After an open lung biopsy, a potential complication is pneumothorax, often indicated by reduced or absent breath sounds. The nurse should promptly notify the physician to address this serious issue and ensure timely intervention.

5. When planning care, what factors should the nurse consider when utilizing evidence-based practice (EBP)? (Select ONE that does not apply)

• A. Cost-saving measures
• B. Nurse's expertise
• C. Client preferences
• D. Research findings

Correct answer: A

Rationale: In evidence-based practice (EBP), nurses should consider the current evidence (research findings), client preferences, and the nurse's expertise when planning care. By integrating these factors, nurses can provide individualized, effective, and patient-centered care that aligns with the best available evidence, the patient's values, and the nurse's clinical knowledge and experience.
