Question 1 of 5
When a patient is experiencing digoxin toxicity, which clinical situation would necessitate the use
Correct Answer: A
Rationale: A: The patient reports seeing colorful halos around lights is A common symptom of digoxin toxicity that indicates visual disturbances.
Question 2 of 5
Route of drug administration where the drug is placed directly into the GIT from where absorption occurs.
Correct Answer: A
Rationale: Enteral route of drug administration involves placing the drug directly into the gastrointestinal tract (such as oral or rectal routes) for absorption into the systemic circulation. This route requires the drug to pass through the digestive system before being absorbed, allowing for slower and more sustained release of the medication compared to other routes. Examples of enteral drug administration include oral tablets, capsules, and liquids as well as rectal suppositories.
Question 3 of 5
Which of the following is defined as the least stimulus intensity at which a subject perceives pain?
Correct Answer: A
Rationale: The pain threshold is defined as the least stimulus intensity at which a subject perceives pain. It represents the point at which a person first acknowledges experiencing pain. Pain threshold varies among individuals and can be influenced by various factors such as genetics, emotional state, culture, and past experiences with pain. It is an important concept in understanding an individual's sensitivity to pain and can be different from their pain tolerance level, which refers to the maximum level of pain a person is willing to endure. Analgesia involves the relief of pain, nociception is the body's physiological response to noxious stimuli, and polymodal refers to nerve fibers that respond to multiple types of stimuli.
Question 4 of 5
A patient is taking ibuprofen. The nurse understands that COX-1 and COX-2 inhibitors are different in that ibuprofen is more likely than celecoxib to cause which adverse effect?
Correct Answer: C
Rationale: Ibuprofen is a non-selective COX inhibitor, meaning it inhibits both COX-1 and COX-2 enzymes. COX-1 is responsible for maintaining the protective lining of the stomach, and its inhibition can lead to gastrointestinal adverse effects such as peptic ulcer disease. Celecoxib, on the other hand, is a selective COX-2 inhibitor, which primarily targets inflammation and pain without significantly affecting the stomach lining. Therefore, ibuprofen is more likely to cause peptic ulcer disease compared to celecoxib. This distinction is crucial for nurses to understand when managing patients on these medications, as it impacts patient monitoring and education.
Question 5 of 5
A patient is in the emergency department with new-onset atrial fibrillation. Which order for digoxin would most likely have the fastest therapeutic effect?
Correct Answer: D
Rationale: In a patient with new-onset atrial fibrillation who requires rapid initiation of digoxin therapy, the fastest therapeutic effect would be achieved by administering the loading dose intravenously. Option D (Digoxin 1 mg IV push now; then 0.25 mg IV daily) includes an initial IV loading dose of 1 mg, followed by a maintenance dose of 0.25 mg IV daily. IV administration allows for quicker absorption and onset of action compared to oral administration. This loading dose increases the digoxin concentration in the bloodstream more rapidly, leading to a quicker therapeutic effect. Subsequent maintenance doses can then be given orally for long-term management.
