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 client is admitted with a pulmonary embolism (PE). The client is young, healthy, and active, and has no known risk factors for PE. What action by the nurse is most appropriate?

• A. Encourage the client to walk for 5 minutes each hour.
• B. Refer the client for smoking cessation classes.
• C. Teach the client about factor V Leiden testing.
• D. Explain to the client that sometimes no cause for the disease is found.

Correct answer: C

Rationale: The most appropriate action for the nurse in this scenario is to teach the client about factor V Leiden testing. Factor V Leiden is an inherited thrombophilia that can lead to abnormal clotting events, including pulmonary embolism (PE). In a case where a client has no known risk factors for PE, testing for this genetic disorder is crucial to determine if it is a contributing factor. Encouraging the client to walk or referring them to smoking cessation classes, while beneficial for overall health, are not directly relevant to the development of a PE in this specific case. While it is true that sometimes no cause for a disease is found, prematurely assuming this without appropriate investigations may lead to missed opportunities for preventive measures or treatments.

3. A nurse is evaluating a 3-day diet history with a client who has an elevated lipid panel. What meal selection indicates the client is managing this condition well with diet?

• A. A 4-ounce steak, French fries, iceberg lettuce
• B. Baked chicken breast, broccoli, tomatoes
• C. Fried catfish, cornbread, peas
• D. Spaghetti with meat sauce, garlic bread

Correct answer: B

Rationale: The diet recommended for this client would be low in saturated fats & red meat, high in vegetables & whole grains (fiber), low in salt, & low in trans-fat. The best choice is the chicken with broccoli & tomatoes. The French fries have too much fat & the iceberg lettuce has little fiber. The catfish is fried. The spaghetti dinner has too much red meat & no vegetables.

4. A client developed fat embolism syndrome (FES) following a fracture. Which of the following laboratory findings should the nurse expect?

• A. Decreased serum calcium level
• B. Decreased level of serum lipids
• C. Decreased erythrocyte sedimentation rate (ESR)
• D. Increased platelet count

Correct answer: A

Rationale: In fat embolism syndrome (FES), fat globules enter the bloodstream and can lead to various complications, including a decrease in serum calcium levels. This occurs due to the formation of fat emboli in the vessels, which can interfere with calcium metabolism. Therefore, a decreased serum calcium level is an expected laboratory finding in a client with fat embolism syndrome.

5. A client had an inferior wall myocardial infarction (MI). The nurse notes the client's cardiac rhythm as shown below. What action by the nurse is most important?

• A. Assess the client's blood pressure and level of consciousness.
• B. Call the health care provider or the Rapid Response Team.
• C. Obtain a permit for an emergency temporary pacemaker insertion.
• D. Prepare to administer antidysrhythmic medication.

Correct answer: A

Rationale: The ECG strip shows sinus bradycardia, which is common in clients with an inferior wall MI. This rhythm can lead to decreased perfusion due to bradycardia and blocks. The most crucial initial action for the nurse is to assess the client's hemodynamic status, including blood pressure and level of consciousness. This assessment will help determine the immediate needs of the client. Calling the health care provider or the Rapid Response Team, obtaining a permit for a pacemaker insertion, or preparing to administer antidysrhythmic medication may be necessary based on the assessment findings, but the priority is to evaluate the client's current condition first.
