Question 1 of 5
A nurse is taking a medication history from a client who has a new prescription for levothyroxine. The nurse should instruct the client to wait 4 hours after taking levothyroxine before taking which of the following supplements?
Correct Answer: C
Rationale: Calcium is known to interfere with the absorption of levothyroxine. Calcium supplements can bind to levothyroxine in the gastrointestinal tract, reducing its absorption.
Therefore, it is recommended to wait at least 4 hours after taking levothyroxine before consuming calcium supplements.
Question 2 of 5
A nurse is preparing to administer the varicella vaccine to a group of clients. The nurse should identify which of the following clients as having a contraindication for receiving this immunization?
Correct Answer: C
Rationale: A client who has AIDS is a contraindication for the varicella vaccine. Individuals with severe immunocompromising conditions, such as AIDS, should not receive live vaccines like the varicella vaccine due to the risk of severe vaccine-related complications.
Question 3 of 5
A nurse is preparing to administer cefazolin 1 g in 0.9% sodium chloride 100 mL via intermittent IV bolus over 30 minutes. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 50
Rationale:
Step 1: Determine the total volume (100 mL).
Step 2: Determine the time (30 minutes).
Step 3: Calculate the flow rate in mL/min (100 mL ÷ 30 min = 3.33 mL/min).
Step 4: Calculate gtt/min (3.33 mL/min × 15 gtt/mL = 49.95 gtt/min).
Step 5: Round to 50 gtt/min.
Question 4 of 5
A nurse is preparing to mix short-acting insulin with NPH insulin from two vials. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: Inject air into the vial to withdraw the short-acting insulin is the correct procedure. The nurse should first inject air into the NPH vial without drawing up any insulin, then inject air into the short-acting insulin vial and withdraw the required dose. This prevents contamination of the short-acting insulin with NPH insulin.
Question 5 of 5
A nurse is caring for a client who is receiving total parenteral nutrition. The nurse should monitor the client for which of the following adverse effects?
Correct Answer: C
Rationale: Electrolyte imbalance is a significant adverse effect of TPN. TPN solutions contain various electrolytes, and improper formulation or administration can lead to imbalances, which can cause serious complications such as cardiac arrhythmias, muscle weakness, and neurological issues.
