1. 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 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. Choice B, 24 gtt/min, is incorrect as it results from a miscalculation. Choices C and D, 20 gtt/min and 18 gtt/min respectively, are also incorrect calculations based on the given parameters.
2. A client has a new prescription for a Fentanyl transdermal patch. Which of the following instructions should the nurse include?
- A. Apply the patch to a non-hairy area.
- B. Change the patch every 72 hours.
- C. Avoid exposure to heat sources.
- D. Do not cut the patch to adjust the dosage.
Correct answer: C
Rationale: The correct instruction the nurse should include for a client using a Fentanyl transdermal patch is to avoid exposure to heat sources. Heat can increase the absorption of the medication, potentially causing an overdose. Instructing the client to avoid heat sources is crucial to ensure their safety and the effectiveness of the medication. Choices A, B, and D are incorrect because applying the patch to a non-hairy area, changing it every 72 hours, and not cutting the patch are general guidelines for using transdermal patches but do not specifically address the unique risks associated with Fentanyl patches.
3. A client has a new prescription for clonidine to treat hypertension. Which of the following instructions should the nurse include?
- A. Discontinue the medication if a rash develops.
- B. Expect increased salivation during the first few weeks of therapy.
- C. Avoid driving until the client's reaction to the medication is known.
- D. Stop the medication if you experience a dry mouth.
Correct answer: C
Rationale: The correct instruction for a client starting clonidine therapy for hypertension is to avoid driving until their reaction to the medication is known. Clonidine can cause drowsiness, so engaging in activities like driving that require alertness should be avoided until the individual understands how the medication affects them. Choices A, B, and D are incorrect because they do not address the specific side effect of drowsiness associated with clonidine that could impair driving abilities. Discontinuing the medication if a rash develops, expecting increased salivation, or stopping the medication for dry mouth are not primary concerns related to clonidine therapy for hypertension.
4. A client who received Prochlorperazine 4 hours ago reports spasms of his face. The nurse should anticipate a prescription for which of the following medications?
- A. Fomepizole
- B. Naloxone
- C. Phytonadione
- D. Diphenhydramine
Correct answer: D
Rationale: An adverse effect of prochlorperazine is acute dystonia, which is evidenced by spasms of the muscles in the face, neck, and tongue. Diphenhydramine is used to suppress extrapyramidal effects of prochlorperazine, making it the most appropriate choice to address the client's spasms. Fomepizole is used in methanol or ethylene glycol poisoning, not for acute dystonia. Naloxone is an opioid antagonist used for opioid overdose, not for acute dystonia. Phytonadione is vitamin K, used for the reversal of warfarin, not for acute dystonia.
5. A client with cancer and a prescription for methotrexate PO reports bleeding gums while being assessed by a nurse in a provider's clinic. Which of the following actions should the nurse take?
- A. Explain to the client that this is an expected adverse effect.
- B. Check the value of the client's current platelet count.
- C. Instruct the client to use an electric toothbrush.
- D. Have the client make an appointment to see the dentist.
Correct answer: B
Rationale: The correct action for the nurse to take when a client on methotrexate reports bleeding gums is to check the client's current platelet count. Bleeding gums may indicate thrombocytopenia, a decreased platelet count which can be a severe side effect of methotrexate therapy. Monitoring the platelet count is crucial for early detection and management of this potentially life-threatening complication. Choice A is incorrect as bleeding gums in this context may not be an expected adverse effect of methotrexate. Choice C is irrelevant and does not address the potential underlying issue of thrombocytopenia. Choice D is not the primary action needed at this point; checking the platelet count is more urgent to assess the severity of the situation.
