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 with a pleural effusion is being assessed by a nurse. Which clinical manifestation does the nurse expect to find?

• A. Decreased breath sounds on the affected side
• B. Hyperresonance on percussion of the affected side
• C. Increased tactile fremitus on the affected side
• D. Tracheal deviation toward the affected side

Correct answer: A

Rationale: In a client with pleural effusion, decreased breath sounds on the affected side are common due to the presence of fluid in the pleural space. Hyperresonance is not expected; dullness on percussion is more likely. Tactile fremitus is typically decreased, not increased, in pleural effusion cases. Tracheal deviation away from the affected side, not toward it, can be seen with large effusions.

3. During a home visit to an older client living alone post-coronary artery bypass graft, what finding prompts the nurse to consider additional referrals?

• A. Dirty carpets requiring vacuuming
• B. Expired food found in the refrigerator
• C. Outdated medications stored in the kitchen
• D. Presence of multiple cats in the home

Correct answer: B

Rationale: The presence of expired food in the refrigerator is concerning as it raises safety issues for the client and indicates potential financial constraints preventing them from buying fresh food. The nurse should consider referring the client to services like Meals on Wheels or other home-based food programs to address this issue and ensure the client's nutritional needs are met.

4. A client has a tracheostomy that is 3 days old. Upon assessment, the nurse notes the client's face is puffy, and the eyelids are swollen. What action by the nurse takes priority?

• A. Assess the client's oxygen saturation.
• B. Notify the Rapid Response Team.
• C. Oxygenate the client with a bag-valve-mask.
• D. Palpate the skin of the upper chest.

Correct answer: A

Rationale: In this scenario, the client may have subcutaneous emphysema, where air leaks into the tissues surrounding the tracheostomy. The priority action for the nurse is to assess the client's oxygen saturation and other indicators of oxygenation to ensure adequate oxygen supply. If the client is stable, the nurse can then proceed to palpate the skin of the upper chest to check for subcutaneous emphysema. If the client is unstable, the nurse should promptly notify the Rapid Response Team. Using a bag-valve-mask device may be necessary for oxygenating the client, but assessing oxygen saturation comes first to guide further interventions.

5. A client is experiencing an acute exacerbation of asthma. Which medication should the nurse administer first?

• A. Albuterol (Proventil)
• B. Ipratropium (Atrovent)
• C. Salmeterol (Serevent)
• D. Fluticasone (Flovent)

Correct answer: A

Rationale: During an acute exacerbation of asthma, the priority is to administer a short-acting beta2-agonist like Albuterol (Proventil) first. Albuterol acts quickly to dilate the airways and provide immediate relief of bronchospasm. Ipratropium (Atrovent) is an anticholinergic that can be used as an adjunct therapy. Salmeterol (Serevent) is a long-acting beta2-agonist intended for maintenance therapy, not for acute exacerbations. Fluticasone (Flovent) is a corticosteroid used for long-term asthma control and should not be the initial medication given during an acute exacerbation.
