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 healthcare professional is preparing to administer a transfusion of 300 mL of pooled platelets for a client with severe Thrombocytopenia. How should the healthcare professional plan to administer the transfusion over which of the following time frames?

• A. Within 30 minutes/unit
• B. Within 60 minutes/unit
• C. Within 2 hours/unit
• D. Within 4 hours/unit

Correct answer: A

Rationale: Platelets are fragile components that must be administered promptly to minimize the risk of clumping. The correct administration time for platelets is within 15 to 30 minutes per unit to maintain their therapeutic effectiveness and reduce adverse effects. Administering platelets over longer time frames can lead to decreased efficacy and potential harm to the patient. Therefore, the correct answer is to administer the 300 mL of pooled platelets within 30 minutes per unit.

3. A client has a new prescription for a combination of oral NRTIs (abacavir, lamivudine, and zidovudine) for the treatment of HIV. Which of the following statements should the nurse include in teaching the client?

• A. These medications work by blocking HIV entry into cells.
• B. These medications work by weakening the cell wall of the HIV virus.
• C. These medications work by inhibiting enzymes to prevent HIV replication.
• D. These medications work by preventing protein synthesis within the HIV cell.

Correct answer: C

Rationale: The NRTI antiretroviral medications this client is prescribed work by inhibiting the enzyme reverse transcriptase, thus preventing HIV replication. By inhibiting this crucial enzyme, the drug interferes with the virus's ability to replicate and spread in the body. Choice A is incorrect because NRTIs do not block HIV entry into cells. Choice B is incorrect as NRTIs do not weaken the cell wall of the virus. Choice D is incorrect as NRTIs do not prevent protein synthesis within the HIV cell.

4. A client has a new prescription for Verapamil to treat angina. Which of the following client statements should indicate to the nurse that the client is experiencing an adverse effect of Verapamil?

• A. I am frequently constipated.
• B. I have been urinating more frequently.
• C. My skin is peeling.
• D. I have ringing in my ears.

Correct answer: A

Rationale: The correct answer is A: 'I am frequently constipated.' Constipation is a common adverse effect of Verapamil, a calcium channel blocker. Verapamil can slow down intestinal motility, leading to constipation as a side effect. Choices B, C, and D are not typically associated with adverse effects of Verapamil. Increased urination is not a common side effect, skin peeling is not related to Verapamil use, and ringing in the ears is not a typical adverse effect of this medication.

5. A client is receiving moderate sedation with Diazepam IV and is oversedated. Which of the following medications should the nurse anticipate administering to this client?

• A. Ketamine
• B. Naltrexone
• C. Flumazenil
• D. Fluvoxamine

Correct answer: C

Rationale: Flumazenil is a competitive benzodiazepine antagonist that can reverse the sedative effects of benzodiazepines like Diazepam. In cases of oversedation, administering Flumazenil can help counteract the excessive sedation and other effects of Diazepam, thereby promoting the client's recovery and preventing potential complications. Ketamine (Choice A) is a dissociative anesthetic and not used to reverse benzodiazepine sedation. Naltrexone (Choice B) is an opioid receptor antagonist, not indicated for benzodiazepine oversedation. Fluvoxamine (Choice D) is an antidepressant and not used to reverse the sedative effects of benzodiazepines.
