Nursing Elites

1. What is the most common cause of acute renal failure?

• A. Shock
• B. Nephrotoxic drugs
• C. Enlarged prostate
• D. Diabetes

Correct answer: A

Rationale: The most common cause of acute renal failure is shock. In cases of shock, such as hypovolemic shock where there is low blood volume, the kidneys receive inadequate blood flow leading to acute renal failure. This can result in the kidneys starting to die within 20 minutes of low pressure. While nephrotoxic drugs can also cause acute renal failure, shock is more commonly associated with this condition. An enlarged prostate can lead to urinary retention but is not the most common cause of acute renal failure. Diabetes, on the other hand, can cause chronic kidney disease over time but is not typically the primary cause of acute renal failure.

2. What advice should be given to a client with stress incontinence?

• A. to consider trying Kegel exercises
• B. to undergo surgery immediately
• C. to avoid all forms of treatment
• D. to ignore the issue as it is not serious

Correct answer: A

Rationale: For stress incontinence, advising the client to consider trying Kegel exercises is appropriate. Kegel exercises involve tightening and releasing the pelvic floor muscles, which can improve stress incontinence by strengthening the muscles that control urination. Choice B suggesting immediate surgery is incorrect as surgery is usually considered after conservative treatments like Kegel exercises have been tried. Choice C advising to avoid all forms of treatment is dangerous and neglectful. Choice D recommending to ignore the issue is inappropriate as it can impact the client's quality of life and may worsen over time without intervention.

3. Acyclovir is the drug of choice for:

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

Correct answer: C

Rationale: Acyclovir (Zovirax) is specifically used to treat infections caused by herpes simplex virus types 1 and 2 (HSV-1 and HSV-2) and varicella-zoster virus (VZV). These include conditions like cold sores, genital herpes, and shingles. Acyclovir works by inhibiting viral DNA replication, leading to the formation of shorter, ineffective DNA chains. It is important to note that acyclovir is not effective against other viruses like HIV, cytomegalovirus (CMV), or influenza A viruses. Therefore, the correct answer is HSV 1 and 2 and VZV.

4. What is one characteristic of human immunodeficiency virus (HIV)?

• A. The presence of circulating antibodies that neutralize HIV is evidence of exposure to HIV.
• B. HIV replication occurs intracellularly.
• C. HIV integrates its genetic material into the host cell's DNA.
• D. DNA replication is irrelevant to HIV.

Correct answer: C

Rationale: The correct answer is C. HIV integrates its genetic material into the host cell's DNA. The virus uses the enzyme reverse transcriptase to make a DNA copy of its RNA, which is then inserted into the genetic material of the infected cell. Choice A is incorrect because the presence of antibodies does not indicate immunity to HIV but rather exposure to the virus. Choice B is incorrect as HIV replication occurs intracellularly, inside the host cell. Choice D is irrelevant to the characteristics of HIV.

5. The nurse is obtaining a health assessment from the preoperative client scheduled for hip replacement surgery. Which statement by the client would be most important for the nurse to report to the physician?

• A. "I had chickenpox when I was 8 years old."?
• B. "I had rheumatic fever when I was 10 years old."?
• C. "I have a strong family history of gastric cancer."?
• D. "I have pain in my hip with any movement."?

Correct answer: B

Rationale: The most important statement for the nurse to report to the physician is that the client had rheumatic fever when they were 10 years old. This information is crucial as individuals who have had rheumatic fever require pre-medication with antibiotics before any surgical or dental procedure to prevent bacterial endocarditis. Reporting this history ensures the client's safety during the hip replacement surgery. The other options, such as having chickenpox in the past, a family history of gastric cancer, or experiencing hip pain, are important for the client's overall health assessment but do not have the same immediate implications for the upcoming surgery as the history of rheumatic fever.
