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 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.

3. A client is postoperative with shallow respirations at 9/min. Which acid-base imbalance should the nurse identify the client as being at risk for developing initially?

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

Correct answer: A

Rationale: The client's shallow respirations at 9/min indicate hypoventilation, leading to an accumulation of carbon dioxide in the blood, causing respiratory acidosis. In this scenario, the client is at risk for developing respiratory acidosis due to inadequate ventilation and subsequent CO2 retention.

4. A client with a tracheostomy experienced a coughing spell during a meal that was being fed by an unlicensed assistive personnel (UAP). What action by the nurse takes priority?

• A. Assess the client's lung sounds.
• B. Assign a different UAP to the client.
• C. Report the UAP to the manager.
• D. Request thicker liquids for meals.

Correct answer: A

Rationale: The priority action for the nurse is to assess the client's lung sounds to check for signs of aspiration, which can compromise the client's oxygenation. This is crucial to ensure the client's immediate safety and respiratory status. Once the client has been assessed, the nurse can then consider consulting with the registered dietitian regarding appropriate thickened liquids for future meals. Assigning a different UAP or reporting the UAP to the manager may be necessary steps but not the immediate priority in this situation.

5. A healthcare provider assesses a client with pneumonia. Which clinical manifestation should the provider expect to find?

• A. Fremitus
• B. Hyperresonance
• C. Dullness on percussion
• D. Decreased tactile fremitus

Correct answer: C

Rationale: Pneumonia often leads to the consolidation of lung tissue, resulting in dullness on percussion. This occurs due to the presence of fluid or inflammatory material in the alveoli. Fremitus and decreased tactile fremitus are more indicative of conditions like pleural effusion or pneumothorax, where there is an increase in the density of the pleural space or air in the pleural cavity. Hyperresonance, on the other hand, is typically associated with conditions causing air trapping, such as emphysema, where there is increased air in the alveoli.
