Nursing Elites

1. The provider requests the nurse to start an infusion of an inotropic agent on a client. How should the nurse explain the action of these drugs to the client and spouse?

• A. It constricts vessels, improving blood flow.
• B. It dilates vessels, which lessens the work of the heart.
• C. It increases the force of the heart's contractions.
• D. It slows the heart rate down for better filling.

Correct answer: C

Rationale: An inotropic agent is a medication that increases the force of the heart's contractions, which helps improve cardiac output. Choice A and B are incorrect as inotropic agents do not constrict or dilate vessels. Choice D is also incorrect as inotropic agents do not slow down the heart rate but rather enhance the heart's contractility.

2. A client had a bronchoscopy 2 hours ago and asks for a drink of water. Which action should the nurse take next?

• A. Call the healthcare provider to request a prescription for food and water.
• B. Provide the client with ice chips instead of a drink of water.
• C. Assess the client's gag reflex before giving any food or water.
• D. Let the client have a small sip to assess swallowing ability.

Correct answer: C

Rationale: After a bronchoscopy, a topical anesthetic affects the gag reflex. Therefore, the nurse should assess the client's gag reflex before providing any food or water to ensure its return. This assessment is crucial to prevent aspiration or choking risk in the client.

3. 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.

4. A client with asthma has developed viral pharyngitis. Which of the following findings should the nurse expect?

• A. Petechiae on the chest and abdomen
• B. WBC 16,000/mm3
• C. Negative throat culture
• D. Severe hyperemia of pharyngeal mucosa

Correct answer: C

Rationale: Viral pharyngitis is typically caused by a virus, not bacteria, so a negative throat culture is an expected finding. The presence of petechiae on the chest and abdomen (Choice A) is not a common manifestation of viral pharyngitis. Elevated WBC count (Choice B) is more indicative of a bacterial infection rather than a viral one. Severe hyperemia of the pharyngeal mucosa (Choice D) is a possible finding in pharyngitis but is not specific to viral pharyngitis.

5. 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.
