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 healthcare professional is caring for a client who has just developed a pulmonary embolism. Which of the following medications should the healthcare professional anticipate administering?

• A. Furosemide
• B. Dexamethasone
• C. Heparin
• D. Atropine

Correct answer: C

Rationale: In the scenario of a pulmonary embolism, the priority medication to administer is Heparin. Heparin is an anticoagulant that helps prevent the formation of new blood clots and the growth of existing ones, which is crucial in managing pulmonary embolism. Furosemide is a diuretic used to treat fluid retention, Dexamethasone is a corticosteroid used for inflammation, and Atropine is an anticholinergic medication used for various purposes such as treating bradycardia.

3. What should the nurse prioritize when monitoring an older adult client immediately following a bronchoscopy?

• A. Observing for confusion
• B. Auscultating breath sounds
• C. Confirming the gag reflex
• D. Measuring blood pressure

Correct answer: C

Rationale: Following a bronchoscopy, the priority for the nurse is to confirm the gag reflex in the older adult client. This is crucial to ensure that the client's airway is protected and free from any obstruction or aspiration. Monitoring the gag reflex helps in preventing complications such as aspiration pneumonia. While auscultating breath sounds, observing for confusion, and measuring blood pressure are important assessments, confirming the gag reflex takes precedence in this situation to maintain airway patency and prevent potential respiratory complications.

4. A client with tuberculosis is starting combination drug therapy. Which of the following medications should the nurse NOT plan to administer?

• A. Rifampin
• B. Isoniazid
• C. Acyclovir
• D. Pyrazinamide

Correct answer: C

Rationale: Acyclovir is an antiviral medication used to treat herpes virus infections, not tuberculosis. Rifampin, Isoniazid, and Pyrazinamide are all commonly used in the treatment of tuberculosis. Therefore, the nurse should not plan to administer Acyclovir to a client with tuberculosis.

5. A client with Parkinson's disease is prescribed carbidopa-levodopa (Sinemet). What should the nurse include in the teaching about this medication?

• A. Take the medication without a high-protein meal.
• B. Expect the medication to take several weeks to reach full effectiveness.
• C. The medication may cause urine to turn light.
• D. You may experience a rapid heartbeat as a common side effect.

Correct answer: B

Rationale: Patients prescribed carbidopa-levodopa should be informed that it may take several weeks for the medication to reach its full therapeutic effectiveness in managing Parkinson's disease symptoms. This delayed onset of action is important for patients to be aware of to prevent premature discontinuation of the medication due to perceived lack of efficacy.
