Nursing Elites

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 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.

3. During an admission assessment of a client with COPD and emphysema complaining of a frequent productive cough and shortness of breath, what assessment finding should the nurse anticipate?

• A. Respiratory alkalosis
• B. Increased anteroposterior diameter of the chest
• C. Oxygen saturation level 96%
• D. Petechiae on chest

Correct answer: B

Rationale: COPD and emphysema are chronic respiratory conditions that can lead to changes in the shape of the chest. In clients with COPD, the anteroposterior diameter of the chest often increases, giving a barrel chest appearance. This change in chest shape is due to hyperinflation of the lungs and is a common physical finding in clients with COPD and emphysema. The other options are not typically associated with COPD and emphysema. Respiratory alkalosis is not a common finding in these clients. An oxygen saturation level of 96% is within the normal range and does not specifically relate to COPD. Petechiae on the chest are not typically associated with COPD or emphysema.

4. A client with emphysema is being assessed by a nurse. Which clinical manifestation should the nurse expect?

• A. Decreased chest expansion
• B. Cyanosis
• C. Pursed-lip breathing
• D. Bradypnea

Correct answer: C

Rationale: Pursed-lip breathing is a common manifestation in clients with emphysema. It helps to increase the duration of exhalation and reduce air trapping, aiding in the management of the condition. Decreased chest expansion and bradypnea are not typically associated with emphysema. While cyanosis can occur in severe cases, pursed-lip breathing is a more specific and commonly observed sign of emphysema.

5. 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.
