Nursing Elites

1. A healthcare professional is preparing a client for a colonoscopy. Which of the following medications should the professional anticipate the provider to prescribe as an anesthetic for the procedure?

• A. Propofol
• B. Pancuronium
• C. Promethazine
• D. Pentoxifylline

Correct answer: A

Rationale: The correct answer is A, Propofol. Propofol is a short-acting anesthetic medication commonly used for procedures like colonoscopies to induce moderate sedation. Pancuronium (Choice B) is a neuromuscular blocking agent used as a paralyzing agent during surgery, not for sedation. Promethazine (Choice C) is an antihistamine often used for nausea and vomiting, not as an anesthetic. Pentoxifylline (Choice D) is a medication used to improve blood flow and is not indicated for anesthesia.

2. A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50, PaCO2 29 mm Hg, and HCO3- 25 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

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

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is experiencing respiratory alkalosis due to hyperventilation. Hyperventilation leads to excessive loss of carbon dioxide, causing a decrease in hydrogen ion concentration and an increase in pH levels. Choices A, C, and D are incorrect. Respiratory acidosis is characterized by high PaCO2 and low pH. Metabolic acidosis is associated with low HCO3- levels and low pH. Metabolic alkalosis is marked by high HCO3- levels and high pH. In this case, the ABG results indicate respiratory alkalosis.

3. What is the primary nursing action for a patient experiencing continuous bubbling in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Clamp the chest tube
• C. Continue monitoring the chest tube
• D. Replace the chest tube system

Correct answer: A

Rationale: The correct answer is to tighten the connections of the chest tube system. Continuous bubbling in the chest tube water seal chamber indicates an air leak. By tightening the connections of the chest tube system, the nurse can often resolve the issue by ensuring there are no loose connections allowing air to enter. Clamping the chest tube or replacing the chest tube system are not appropriate actions in this situation. Clamping the tube can cause a dangerous buildup of pressure, while replacing the system should only be considered if tightening the connections does not resolve the air leak.

4. What are the expected signs of compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Fever, swelling, and redness
• C. Muscle cramps and weakness
• D. Redness and itching

Correct answer: A

Rationale: The correct answer is A: Unrelieved pain, pallor, and pulselessness. Compartment syndrome is characterized by increased pressure within a muscle compartment, leading to inadequate blood supply. This results in severe pain that is unrelieved by rest or medication, pallor due to compromised blood flow, and pulselessness as a late sign of severe ischemia. Choices B, C, and D are incorrect. Fever, swelling, and redness are not typical signs of compartment syndrome. Muscle cramps and weakness may occur due to other conditions, but they are not primary indicators of compartment syndrome. Redness and itching are also not commonly associated with compartment syndrome.

5. What is the preferred treatment for a patient with unstable angina admitted with chest pain?

• A. Administer sublingual nitroglycerin
• B. Establish IV access
• C. Auscultate heart sounds
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: The correct answer is to administer sublingual nitroglycerin. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart, relieving chest pain, and preventing cardiac tissue damage. Establishing IV access (choice B) is important but not the preferred initial treatment for unstable angina with chest pain. Auscultating heart sounds (choice C) and obtaining cardiac enzymes (choice D) are relevant assessments but do not address the immediate symptomatic relief needed for a patient with unstable angina and chest pain.
