Nursing Elites

1. What is the antidote for Warfarin?

• A. Naloxone
• B. Vitamin K
• C. Glucagon
• D. Vitamin B

Correct answer: B

Rationale: The correct antidote for Warfarin is Vitamin K. Warfarin works by inhibiting vitamin K-dependent clotting factors. Administering Vitamin K helps reverse its effects by replenishing these factors. Choices A, C, and D are incorrect. Naloxone is used to reverse opioid overdose, Glucagon is used to treat severe low blood sugar, and Vitamin B is not the antidote for Warfarin.

2. A client has a new prescription for Ondansetron for nausea and vomiting associated with chemotherapy. Which of the following statements should the nurse include?

• A. Take this medication one hour before chemotherapy.
• B. You may experience a headache while taking this medication.
• C. Increase your intake of potassium while taking this medication.
• D. This medication may cause temporary hearing loss.

Correct answer: B

Rationale: The correct statement the nurse should include is that the client may experience a headache while taking Ondansetron. Headache is a common side effect of this medication, and clients need to be informed about this potential adverse reaction to enhance their understanding and management of side effects. The other statements are incorrect because Ondansetron is usually taken 30 minutes before chemotherapy, not one hour before (choice A). There is no specific need to increase potassium intake while taking Ondansetron (choice C), and temporary hearing loss is not a common side effect associated with this medication (choice D).

3. A client has a new prescription for Ranitidine. Which of the following instructions should the nurse include?

• A. Take the medication with an antacid.
• B. Avoid drinking coffee while taking this medication.
• C. Take the medication at bedtime.
• D. Stop the medication if you develop a headache.

Correct answer: C

Rationale: The correct instruction for a client prescribed Ranitidine is to take the medication at bedtime. Ranitidine is best taken at night to reduce nighttime stomach acid production, providing optimal relief for conditions like gastroesophageal reflux disease (GERD) and ulcers.

4. A client is prescribed Ranitidine. Which of the following laboratory results should be monitored by the nurse?

• A. Complete blood count (CBC).
• B. Serum creatinine.
• C. Serum potassium.
• D. Serum glucose.

Correct answer: A

Rationale: Ranitidine can potentially lead to blood dyscrasias, necessitating the monitoring of the client's CBC. Checking the CBC can help detect any abnormalities in blood cell counts and assess the client's overall hematologic status during Ranitidine therapy.

5. A client is receiving heparin therapy. Which laboratory value should be monitored by the nurse to evaluate the effectiveness of the therapy?

• A. PT
• B. aPTT
• C. INR
• D. Platelet count

Correct answer: B

Rationale: The activated partial thromboplastin time (aPTT) is specifically used to monitor the effectiveness of heparin therapy. It should be maintained at 1.5 to 2 times the normal level. Monitoring aPTT helps ensure that the therapeutic range of heparin is achieved to prevent clot formation while minimizing the risk of bleeding complications. Choice A (PT) is incorrect as it is used to monitor warfarin therapy, not heparin. Choice C (INR) is also incorrect as it is primarily used to monitor warfarin therapy. Choice D (Platelet count) is not directly related to monitoring the effectiveness of heparin therapy.
