Question 1 of 5
A healthcare professional is preparing to administer vancomycin 1 g by intermittent IV bolus. Available is vancomycin 1 g in 100 mL of dextrose 5% in water (D5W) to infuse over 45 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the healthcare professional adjust the manual IV infusion to deliver?
Correct Answer: A
Rationale: To determine the flow rate in drops per minute (gtt/min), you can use the formula: (Volume in mL x Drop factor) / Time in minutes = Flow rate in gtt/min. In this case, it would be (100 mL x 10 gtt/mL) / 45 min = 22 gtt/min. Therefore, the healthcare professional should adjust the manual IV infusion to deliver 22 gtt/min.
Question 2 of 5
A healthcare professional is preparing to administer an IM dose of penicillin to a client who has a new prescription. The client states she took penicillin 3 years ago and developed a rash. Which of the following actions should the healthcare professional take?
Correct Answer: B
Rationale: The healthcare professional should withhold the medication and notify the provider of the client's previous reaction to penicillin. This information is crucial for the provider to prescribe an alternative antibiotic. Allergic reactions to penicillin can range from mild to severe anaphylaxis, so prior sensitization should be reported to the provider to avoid potential adverse reactions.
Question 3 of 5
A nurse on a medical-surgical unit administers a hypnotic medication to an older adult client at 2100. The next morning, the client is drowsy and wants to sleep instead of eating breakfast. Which of the following factors should the nurse identify as a possible reason for the client's drowsiness?
Correct Answer: C
Rationale: In older adults, reduced hepatic function can lead to prolonged effects of medications metabolized by the liver. This situation can result in increased drug levels in the body, causing drowsiness and other side effects. Adjusting the dosage of the hypnotic medication may be necessary to prevent such adverse effects in older adult clients.
Question 4 of 5

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
When assessing a client taking Lithium Carbonate for Bipolar disorder, which finding should the nurse recognize as a possible indication of toxicity to this medication?
Correct Answer: B
Rationale: Coarse tremors are a common sign of Lithium toxicity. Monitoring for tremors is crucial as they can indicate a potentially serious complication that requires immediate intervention. While other options such as severe hypertension, constipation, and muscle spasm may be symptoms of various conditions, they are not typically associated with Lithium toxicity.
