ATI Pharmacology Final Exam I Questions
Extract:
Question 1 of 5
A client is receiving Total Parenteral Nutrition (TPN) while admitted in the inpatient setting. Which of the following conditions can occur if the nurse abruptly stops TPN?
Correct Answer: C
Rationale: Abrupt cessation of TPN stops the glucose supply suddenly, risking hypoglycemia. TPN is high in dextrose, so stopping it without tapering can cause dangerous blood sugar drops.
Question 2 of 5
The nurse is preparing to administer digoxin (Lanoxin) to a client experiencing atrial fibrillation. Which of the following electrolyte imbalances would the nurse assess to reduce the incidence of toxicity with digoxin?
Correct Answer: B
Rationale: Hypokalemia, or low potassium levels, significantly increases the risk of digoxin toxicity. Potassium and digoxin compete for binding at the same sites in the heart, and low potassium levels enhance digoxin's effects, potentially leading to toxicity.
Question 3 of 5
A client has overdosed on scopolamine (Scopace) while being treated for motion sickness. The nurse recognizes she will administer which reversal medication for an anticholinergic overdose?
Correct Answer: C
Rationale: Physostigmine is an acetylcholinesterase inhibitor that reverses anticholinergic toxicity, such as scopolamine overdose.
Question 4 of 5
A client is receiving Total Parenteral Nutrition (TPN) while admitted in the inpatient setting. Which of the following conditions can occur if the nurse abruptly stops TPN?
Correct Answer: C
Rationale: Abrupt cessation of TPN stops the glucose supply suddenly, risking hypoglycemia. TPN is high in dextrose, so stopping it without tapering can cause dangerous blood sugar drops.
Question 5 of 5
A nurse is preparing to administer aspirin 650 mg PO every 12 hr. The amount available is aspirin 325 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale:
To calculate the number of tablets: 650 mg (required dose) ÷ 325 mg/tablet (available dose) = 2 tablets. The answer is a whole number, so no rounding is needed.
