1. A client with thrombophlebitis receiving heparin by continuous IV infusion asks the nurse how long it will take for the heparin to dissolve the clot. Which of the following responses should the nurse give?
- A. It usually takes heparin at least 2 to 3 days to reach a therapeutic blood level.
- B. A pharmacist is the person to answer that question.
- C. Heparin does not dissolve clots. It stops new clots from forming.
- D. The oral medication you will take after this IV will dissolve the clot.
Correct answer: C
Rationale: The correct response is C. Heparin does not dissolve clots; it prevents new clots from forming. Heparin works by inhibiting the formation of new clots and the extension of existing clots, rather than directly dissolving them. The client should be informed that the purpose of heparin therapy is to prevent the clot from getting larger and to reduce the risk of new clots forming. Choices A, B, and D are incorrect. Choice A talks about reaching a therapeutic blood level of heparin, which is not related to clot dissolution. Choice B deflects the question to a pharmacist without providing relevant information. Choice D inaccurately suggests that an oral medication will dissolve the clot, which is not the mechanism of action for heparin.
2. A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and has muscle weakness. The nurse should anticipate a prescription for which of the following medications?
- A. Neostigmine
- B. Naloxone
- C. Dantrolene
- D. Vecuronium
Correct answer: A
Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers, such as the one the client received. It works by inhibiting the breakdown of acetylcholine, thereby enhancing neuromuscular transmission and reversing muscle weakness caused by the neuromuscular blocking agent.
3. A client requests information on the use of Feverfew. Which of the following responses should the nurse make?
- A. It is used to treat skin infections.
- B. It can decrease the frequency of migraine headaches.
- C. It can lessen 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: Feverfew is commonly used to decrease the frequency of migraine headaches. However, it is important to note that it has not been proven to relieve an existing migraine headache. Choices A, C, and D are incorrect as Feverfew is not typically used for treating skin infections, lessening nasal congestion in the common cold, or relieving nausea of morning sickness during pregnancy.
4. A client has a new prescription for Nitroglycerin to treat angina. Which of the following instructions should the nurse include?
- A. Take this medication only when chest pain occurs.
- B. Store the medication in a cool, dry place.
- C. Apply the patch to a different site each time.
- D. Avoid consuming alcohol while taking this medication.
Correct answer: C
Rationale: The correct instruction for the nurse to include is to advise the client to apply the Nitroglycerin patch to a different site each time. This is crucial to prevent skin irritation and ensure consistent absorption of the medication. Rotating application sites is important as it helps maintain the effectiveness of the treatment and reduces the risk of skin reactions. Choice A is incorrect because Nitroglycerin is often used prophylactically to prevent angina episodes rather than just for acute chest pain. Choice B is not relevant to the administration or effectiveness of the medication. Choice D, while generally a good recommendation, is not directly related to the administration of Nitroglycerin.
5. A client has a new prescription for Digoxin to treat heart failure. Which of the following instructions should the nurse include in the teaching?
- A. Contact the provider if the heart rate is less than 60/min.
- B. Check the pulse rate for 30 seconds and multiply the result by 2.
- C. Increase the intake of sodium.
- D. Take with food if nausea occurs.
Correct answer: A
Rationale: The correct answer is A. It is crucial for clients on Digoxin to monitor their heart rate. A heart rate less than 60/min can indicate bradycardia, a potential side effect of Digoxin. Therefore, the client should be instructed to contact the provider if their heart rate is less than 60/min to prevent complications and receive appropriate management. Choices B, C, and D are incorrect. Checking the pulse rate for 30 seconds and multiplying by 2 is not specific to Digoxin administration. Increasing sodium intake is contraindicated as Digoxin can lead to sodium retention. Taking Digoxin with food if nausea occurs is not recommended as it may affect the drug's absorption.
