1. A client's plasma Lithium level is 2.1 mEq/L. Which of the following is an appropriate action by the nurse?
- A. Perform immediate gastric lavage.
- B. Prepare the client for hemodialysis.
- C. Administer an additional oral dose of lithium.
- D. Request a stat repeat of the laboratory test.
Correct answer: A
Rationale: In a client with a plasma lithium level of 2.1 mEq/L, immediate gastric lavage is appropriate for severe toxicity. Gastric lavage can help lower the client's lithium level by removing the unabsorbed lithium from the stomach.
2. 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?
- A. 22 gtt/min
- B. 24 gtt/min
- C. 20 gtt/min
- D. 18 gtt/min
Correct answer: A
Rationale: To calculate the flow rate, use the formula: (Volume in mL x Drop factor) / Time in minutes = Flow rate in gtt/min. In this case, (100 mL x 10 gtt/mL) / 45 min = 22 gtt/min. Thus, the healthcare professional should adjust the manual IV infusion to deliver 22 gtt/min. Choice B, 24 gtt/min, is incorrect because it miscalculates the flow rate. Choices C and D, 20 gtt/min and 18 gtt/min, are also incorrect as they do not accurately calculate the flow rate based on the given information.
3. A healthcare professional is preparing to administer Filgrastim for the first time to a client who has just undergone a bone marrow transplant. Which of the following interventions is appropriate?
- A. Administer subcutaneously in a large muscle mass to prevent injury.
- B. Ensure that the medication is kept at room temperature until just prior to administration.
- C. Invert vial gently to mix well before withdrawing dose.
- D. Discard vial after removing one dose of the medication.
Correct answer: D
Rationale: The correct intervention when preparing to administer Filgrastim is to discard the vial after removing one dose of the medication. This practice helps prevent contamination and ensures the medication's effectiveness. Reusing the vial can lead to contamination and compromise the sterility of the medication, putting the client at risk. Therefore, it is crucial to follow proper aseptic technique and discard the vial after withdrawing the prescribed dose.
4. A healthcare professional is preparing to administer an IV antibiotic to a client who has a systemic infection. Which of the following actions should the professional take first?
- A. Administer an antihistamine prior to the antibiotic.
- B. Monitor the client's urine output.
- C. Check the client's allergy history.
- D. Assess the client's vital signs.
Correct answer: C
Rationale: The first action the healthcare professional should take is to check the client's allergy history before administering the antibiotic to prevent a potential allergic reaction. It is crucial to identify any known allergies to antibiotics to ensure the client's safety and well-being. Administering an antihistamine prior to the antibiotic (Choice A) is not recommended unless an allergic reaction occurs. Monitoring the client's urine output (Choice B) and assessing the client's vital signs (Choice D) are important but not the first step in this situation. Checking the client's allergy history takes precedence to prevent adverse reactions.
5. A client has a prescription for Timolol eye drops for the treatment of glaucoma. Which of the following instructions should the nurse include?
- A. Apply gentle pressure to the nasolacrimal duct for 30 to 60 seconds after application.
- B. Avoid blinking immediately after instilling the drops.
- C. Keep your eyes closed for 5 minutes after application.
- D. Administer the drops directly onto the cornea.
Correct answer: A
Rationale: The correct instruction for the nurse to include is to apply gentle pressure to the nasolacrimal duct for 30 to 60 seconds after application. This technique helps prevent systemic absorption of the medication, reducing the risk of systemic side effects. By applying pressure, the drainage of the medication into the bloodstream through the nasolacrimal duct is minimized, enhancing the drug's local ocular effects. Choices B, C, and D are incorrect because blinking immediately after instilling the drops, keeping eyes closed for 5 minutes, and administering the drops directly onto the cornea are not recommended practices for administering Timolol eye drops.
