Extract:
Question 1 of 5
The nurse is administering the long-acting insulin glargine (Lantus) to the client at 2200. The nurse asks the charge nurse to check the dosage. Which action should the charge nurse implement?
Correct Answer: B
Rationale: Verifying MAR against syringe dosage ensures accuracy, per safety protocols. Timing questions, error forms, or HCP notification are unnecessary unless errors occur.
Question 2 of 5
The nurse practicing in a long term care facility recognizes that elderly clients are at greater risk for drug toxicity than younger adults because of which of the following physiological changes of advancing age?
Correct Answer: B
Rationale: Elders have less body water and more fat. Because elderly persons have decreased lean body tissue/water in which to distribute medications, more drug remains in the circulatory system with potential for drug toxicity. Increased body fat results in greater amounts of fat-soluble drugs being absorbed, leaving less in circulation, thus increasing the duration of action of the drug.
Question 3 of 5
The nurse in the physician's office is instructing an adult about taking penicillin V potassium (Pen-Vee-K) qid. When should the nurse tell him to take the medicine?
Correct Answer: C
Rationale: Penicillin V potassium should be taken on an empty stomach at six-hour intervals to optimize absorption.
Question 4 of 5
The client with arthritis is self-medicating with aspirin, a nonsteroidal anti-inflammatory medication. Which complication should the nurse discuss with the client?
Correct Answer: A
Rationale: High-dose aspirin can cause tinnitus, an early sign of salicylate toxicity, requiring education. Diarrhea, tetany, or paresthesia are less common.
Question 5 of 5
An adult woman has been diagnosed as having hypothyroidism. She is taking Cytomel (liothyronine sodium) 50 mcg daily. Which of the following side effects should the nurse be especially alert for?
Correct Answer: A
Rationale: Cytomel increases metabolic rate, potentially causing angina in patients with cardiovascular risk due to increased cardiac demand.
