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 asthma is taking fluticasone. The nurse should monitor the client for which of the following adverse effects?

• A. Hypoglycemia
• B. Hypertension
• C. Polyuria
• D. Oral candidiasis

Correct answer: D

Rationale: Fluticasone is a corticosteroid often used to manage asthma. One of the common adverse effects associated with inhaled corticosteroids like fluticasone is oral candidiasis, also known as thrush. This fungal infection can develop in the mouth and throat due to the steroid's local immunosuppressive effects. Patients should be advised to rinse their mouths after using inhaled corticosteroids to reduce the risk of oral candidiasis. Monitoring for symptoms such as white patches, sore throat, or difficulty swallowing is essential to detect and manage this adverse effect promptly.

3. A client is hospitalized with a second episode of pulmonary embolism (PE). Recent genetic testing reveals the client has an alteration in the gene CYP2C19. What action by the nurse is best?

• A. Instruct the client to eliminate all vitamin K from the diet.
• B. Prepare preoperative teaching for an inferior vena cava (IVC) filter.
• C. Refer the client to a chronic illness support group.
• D. Teach the client to use a soft-bristled toothbrush.

Correct answer: B

Rationale: Clients with an alteration in the CYP2C19 gene do not metabolize warfarin (Coumadin) well, leading to higher blood levels and more side effects. As this client is a poor candidate for warfarin therapy, the prescriber will most likely recommend the implantation of an inferior vena cava (IVC) filter. This device helps prevent blood clots from reaching the lungs, reducing the risk of pulmonary embolism.

4. What question should a nurse ask a client who has an anteroposterior (AP) chest diameter equal to the lateral chest diameter?

• A. Are you taking any medications or herbal supplements?
• B. Do you have any chronic breathing problems?
• C. How often do you perform aerobic exercise?
• D. What is your occupation and what are your hobbies?

Correct answer: B

Rationale: The correct answer is B. A nurse should ask the client if they have any chronic breathing problems when the anteroposterior (AP) chest diameter is the same as the lateral chest diameter. This finding indicates a barrel chest, which can be associated with chronic respiratory conditions such as chronic obstructive pulmonary disease (COPD) or emphysema. Assessing for chronic breathing problems can help the nurse further evaluate the client's respiratory status and provide appropriate care.

5. A client is receiving oxygen therapy via nasal cannula. Which finding indicates that the therapy is effective?

• A. The client is able to ambulate in the hall without dyspnea.
• B. The client has a respiratory rate of 24 breaths per minute.
• C. The client's oxygen saturation is 92%.
• D. The client has a productive cough.

Correct answer: A

Rationale: The correct answer is A. Effective oxygen therapy should improve the client's ability to perform activities without dyspnea. This indicates that the oxygen therapy is adequately supporting the client's respiratory needs. An oxygen saturation of 92% may suggest the need for a higher flow rate to improve oxygenation. A respiratory rate of 24 breaths per minute is elevated, indicating potential respiratory distress. A productive cough does not necessarily indicate effective oxygen therapy, as it is a symptom of respiratory irritation or infection, not oxygenation status.
