Nursing Elites

1. A nurse is caring for a client newly prescribed doxazosin mesylate. Which of the following instructions should the nurse include in client education regarding taking the first dose of this medication?

• A. Change positions slowly and lie down if dizziness occurs
• B. There is no need to avoid normal activities
• C. Avoid dairy products while taking this medication
• D. Do not eat green leafy vegetables

Correct answer: A

Rationale: Corrected Rationale: First-dose orthostatic hypotension can occur with doxazosin. The nurse should advise the client to change positions slowly and lie down if dizziness occurs. Choice B is incorrect because it does not address the potential side effect of dizziness. Choice C and D are also incorrect as there is no specific dietary restriction related to doxazosin mesylate.

2. A client prescribed hydromorphone for severe pain has a decreased respiratory rate from 16 breaths per minute to 6. Which of the following medications should the nurse prepare to administer?

• A. Flumazenil
• B. Naloxone
• C. Activated charcoal
• D. Aluminum hydroxide

Correct answer: B

Rationale: Naloxone is the correct answer as it is used to reverse opioid-induced respiratory depression. Hydromorphone is an opioid medication that can cause respiratory depression at high doses. Naloxone is an opioid antagonist that competes with opioids at receptor sites, reversing the effects of opioids like hydromorphone. Flumazenil (Choice A) is a benzodiazepine antagonist used for benzodiazepine overdose, not opioid overdose. Activated charcoal (Choice C) is used for toxin ingestion to prevent absorption in the gastrointestinal tract, but it is not indicated for opioid overdose. Aluminum hydroxide (Choice D) is an antacid and would not be the appropriate intervention for respiratory depression caused by opioid overdose.

3. A client with an artificial heart valve is prescribed warfarin therapy. Which of the following laboratory values should the nurse monitor to assess the therapeutic effect of warfarin?

• A. Hemoglobin (Hgb)
• B. Prothrombin time (PT)
• C. Bleeding time
• D. Activated partial thromboplastin time (aPTT)

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT). Warfarin is an anticoagulant medication that works by inhibiting the clotting factors dependent on vitamin K, such as factors II, VII, IX, and X. The prothrombin time (PT) measures the extrinsic pathway and is used to monitor the therapeutic effects of warfarin therapy. Monitoring PT helps assess the time it takes for the blood to clot, ensuring that the anticoagulant effect is within the desired range. Choices A, C, and D are incorrect because hemoglobin (Hgb) measures the amount of hemoglobin in the blood, bleeding time assesses the time it takes for bleeding to stop, and activated partial thromboplastin time (aPTT) is used to monitor heparin therapy, not warfarin therapy.

4. A client receiving epoetin alfa therapy for anemia is being monitored for therapeutic effects. Which of the following laboratory values indicates the medication is effective?

• A. White blood cell count
• B. Hematocrit
• C. Platelet count
• D. Red blood cell count

Correct answer: B

Rationale: The correct answer is B: Hematocrit. An increase in hematocrit levels indicates the effectiveness of epoetin alfa in treating anemia. Hematocrit reflects the percentage of red blood cells in the blood, so an increase in hematocrit signifies an improvement in the patient's red blood cell count and oxygen-carrying capacity. Choices A, C, and D are incorrect because white blood cell count, platelet count, and red blood cell count do not directly reflect the therapeutic effects of epoetin alfa in treating anemia.

5. A nurse is reviewing the medication class benzodiazepines. The nurse would use caution when administering benzodiazepines to which of the below clients?

• A. A client with glaucoma
• B. A client with renal failure
• C. A client with hypertension
• D. A client with insomnia

Correct answer: A

Rationale: The correct answer is A. Benzodiazepines should be used cautiously in clients with glaucoma because these medications can increase intraocular pressure. Choices B, C, and D are incorrect because renal failure, hypertension, and insomnia are not contraindications for administering benzodiazepines.
