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. The healthcare provider is caring for a client who has heart failure and a history of asthma. The provider reviews the orders and recognizes that clarification is needed for which of the following medications?

• A. Carvedilol
• B. Fluticasone
• C. Captopril
• D. Isosorbide dinitrate

Correct answer: B

Rationale: The correct answer is Fluticasone. Carvedilol, Captopril, and Isosorbide dinitrate are commonly used in heart failure management and do not typically pose significant risks for clients with a history of asthma. However, Fluticasone is a corticosteroid used to manage asthma but can potentially worsen heart failure symptoms due to its anti-inflammatory effects. Therefore, the nurse should seek clarification regarding the prescription of Fluticasone for a client with heart failure and a history of asthma.

4. A client had a stroke involving the right cerebral hemisphere. The nurse should monitor for which of the following findings?

• A. Poor impulse control
• B. Inability to discriminate words and letters
• C. Deficits in the right visual field
• D. Motor retardation

Correct answer: A

Rationale: A stroke affecting the right cerebral hemisphere can lead to poor impulse control due to the involvement of this area in regulating behavior and inhibiting impulses. Deficits in the right visual field are associated with stroke affecting the left cerebral hemisphere. Inability to discriminate words and letters may be seen in left cerebral hemisphere strokes. Motor retardation may be observed with strokes affecting motor areas in either hemisphere but is not the most specific finding related to a right cerebral hemisphere stroke.

5. A client in the intensive care unit is receiving teaching before removal of an endotracheal tube. Which of the following instructions should the nurse include in the teaching?

• A. Rest in a side-lying position after the tube is removed.
• B. Use the incentive spirometer every 4 hours after the tube is removed.
• C. Avoid speaking for extended periods.
• D. Vital signs will be monitored by a nurse every 15 minutes in the first hour after the tube is removed.

Correct answer: C

Rationale: It is essential to advise the client to avoid speaking for extended periods after the removal of the endotracheal tube to prevent strain on the vocal cords and allow the airway to recover. Speaking for prolonged periods can lead to irritation and potentially affect the healing process. The other options are also important post-extubation instructions, such as using the incentive spirometer to maintain lung function, positioning in a side-lying position for comfort, and frequent monitoring of vital signs to ensure the client's stability.
