1. When using Nitroglycerine (transdermal), how many hours should you be nitrate-free each day?
- A. 1-2 hours
- B. 5-10 hours
- C. 3-4 hours
- D. 10-12 hours
Correct answer: D
Rationale: When using Nitroglycerine (transdermal), it should be applied for 10-12 hours per day to ensure its effectiveness. A nitrate-free period within the day is essential to prevent the development of tolerance to the medication.
2. A client has a new prescription for Enoxaparin. Which of the following instructions should the nurse include?
- A. Massage the injection site after administration.
- B. Aspirate before injecting the medication.
- C. Administer the medication into the abdomen.
- D. Administer the medication via intramuscular injection.
Correct answer: C
Rationale: The correct answer is to administer the medication into the abdomen. Enoxaparin is a medication that is administered subcutaneously, typically in the abdomen to ensure proper absorption. Massaging the injection site should be avoided as it can lead to bruising or bleeding under the skin. Aspirating before injecting the medication is not necessary for subcutaneous injections like Enoxaparin. Administering the medication via intramuscular injection is incorrect as Enoxaparin should be given subcutaneously.
3. A client asks a nurse about Feverfew. Which response should the nurse provide?
- A. It is used to treat skin infections.
- B. It can decrease the frequency of migraine headaches.
- C. It can lessen the nasal congestion in the common cold.
- D. It can relieve nausea of morning sickness during pregnancy.
Correct answer: B
Rationale: The correct response is B: 'It can decrease the frequency of migraine headaches.' Feverfew is known for reducing the frequency of migraine headaches, but it has not been proven to relieve an existing migraine headache. Choices A, C, and D are incorrect because Feverfew is not used to treat skin infections, lessen nasal congestion in the common cold, or relieve nausea of morning sickness during pregnancy.
4. What is the antidote for copper toxicity?
- A. Glucagon
- B. Aminocaproic acid
- C. Atropine
- D. Penicillamine
Correct answer: D
Rationale: Penicillamine is the specific chelating agent used for copper toxicity. It forms stable complexes with copper, which are then excreted in the urine. Glucagon is used for treating hypoglycemia, aminocaproic acid is used to treat bleeding disorders, and atropine is used as an antidote for certain types of poisoning, such as organophosphate toxicity.
5. A healthcare professional is preparing to administer dextrose 5% in water (D5W) 750 mL IV to infuse over 6 hr. How many mL/hr should the IV pump be set to deliver?
- A. 125 mL/hr
- B. 100 mL/hr
- C. 150 mL/hr
- D. 200 mL/hr
Correct answer: A
Rationale: To calculate the flow rate, divide the total volume by the total time: 750 mL / 6 hr = 125 mL/hr. Therefore, the IV pump should be set to deliver 125 mL/hr to infuse D5W 750 mL over 6 hours. Choice B (100 mL/hr) is incorrect because it does not accurately divide the total volume by the total time. Choice C (150 mL/hr) and Choice D (200 mL/hr) are incorrect as they are not the correct flow rates needed to infuse the D5W solution over the specified time period.
