Nursing Elites

1. What is the drug of choice for herpes simplex virus 1, herpes simplex virus 2, and varicella-zoster virus?

• A. HIV.
• B. HSV 1, HSV 2, and VZV.
• C. CMV
• D. Influenza A viruses.

Correct answer: B

Rationale: Acyclovir (Zovirax) is the drug of choice for herpes simplex virus 1 (HSV-1), herpes simplex virus 2 (HSV-2), and varicella-zoster virus (VZV) infections. It works by inhibiting viral DNA replication. Acyclovir is excreted unchanged in the urine, so caution is needed in renal impairment. Choice A, HIV, is incorrect as acyclovir is not the drug of choice for HIV. Choice C, CMV, is incorrect as acyclovir is not the preferred treatment for cytomegalovirus (CMV) infections. Choice D, Influenza A viruses, is incorrect as acyclovir is not used to treat influenza viruses.

2. A nurse is instructing a patient on the order of sensations with the application of an ice water bath for a swollen right ankle. Which of the following is the correct order of sensations experienced with an ice water bath?

• A. cold, burning, aching, and numbness
• B. burning, aching, cold, and numbness
• C. aching, cold, burning, and numbness
• D. cold, aching, burning, and numbness

Correct answer: A

Rationale: The correct order of sensations experienced with an ice water bath is cold, burning, aching, and numbness, as stated by the acronym CBAN (cold, burn, ache, numbness). Option A is the correct sequence. Choice B is incorrect as it starts with burning, which typically follows the cold sensation. Choice C is incorrect as aching is usually felt after the burning sensation. Choice D is incorrect as aching usually occurs after the burning sensation.

3. The nurse is caring for a client receiving warfarin therapy (Coumadin�) following a stroke. The client's PT/INR was completed at 7:00 A.M. prior to the morning meal with an INR reading of 4.0. Which of the following is the nurse's first priority?

• A. Call the physician to request an increase in the Coumadin� dose.
• B. Administer a vitamin K injection IM and notify the physician of the results.
• C. Assess the client for bleeding around the gums or in the stool and notify the physician of the lab results and latest dose of Coumadin�.
• D. Notify the next shift to hold the daily dose of Coumadin� scheduled for 5:00 P.M.

Correct answer: B

Rationale: In a client receiving warfarin therapy with a high INR of 4.0, the nurse's first priority is to administer a vitamin K injection intramuscularly (IM) and notify the physician of the results. An INR of 4.0 indicates excessive anticoagulation, putting the client at risk of bleeding. Vitamin K is the antidote for warfarin overdose and helps to reverse its effects. It is crucial to administer vitamin K promptly to prevent bleeding complications. Calling the physician to request an increase in the Coumadin� dose is inappropriate and dangerous in this situation, as it would further raise the INR. Assessing the client for bleeding and notifying the physician is important but not the first priority when faced with a critically high INR. Holding the daily dose of Coumadin� may be necessary after administering vitamin K, but it is not the primary action needed to address the acute high INR level.

4. The nurse is providing post-operative care to the craniotomy client. Diabetes insipidus is suspected when the client's urine output suddenly increases significantly. Which action takes highest priority?

• A. Continue to monitor urine output
• B. Check a pulse
• C. Check a blood pressure
• D. Check level of consciousness (LOC)

Correct answer: C

Rationale: The correct answer is to check a blood pressure. Diabetes insipidus can lead to dehydration and potential hypovolemic shock due to excessive urine output. Monitoring blood pressure is crucial to assess the client's circulatory status and detect signs of shock early. Checking the blood pressure will provide essential information on perfusion, which is vital in this situation. Continuing to monitor urine output, checking a pulse, or assessing the level of consciousness are important but not as high a priority as evaluating the blood pressure in a potentially critical situation like suspected diabetes insipidus.

5. When teaching a patient with COPD pulmonary exercises, what should be done?

• A. Teach pursed-lip breathing techniques.
• B. Encourage repetitive heavy lifting exercises to increase strength.
• C. Limit exercises due to respiratory acidosis.
• D. Take breaks every 10-20 minutes during exercises.

Correct answer: A

Rationale: The correct answer is to teach pursed-lip breathing techniques. Pursed-lip breathing helps to decrease the volume of air expelled by keeping the airways open longer, making it easier for patients with COPD to breathe out. Encouraging heavy lifting exercises (Choice B) is not suitable for patients with COPD as it can lead to increased shortness of breath. Limiting exercises due to respiratory acidosis (Choice C) is not correct; instead, exercises should be tailored to the patient's tolerance. Taking breaks every 10-20 minutes (Choice D) is not specific to the management of COPD pulmonary exercises.
