1. A nurse working in a pediatric clinic observes bruises on the body of a four-year-old boy. The parents report the boy fell while riding his bike. The bruises are located on his posterior chest wall and gluteal region. What should the nurse do?
- A. Suggest a script for counseling the family to the doctor on duty.
- B. Recommend a warm bath for the boy to decrease healing time.
- C. Notify the case manager in the clinic about possible child abuse concerns.
- D. Recommend ROM exercises to the patient's spine to decrease healing time.
Correct answer: C
Rationale: In this scenario, the nurse is observing bruises on a child's body that are located in areas not commonly associated with accidental injuries. Given the concerning nature of the bruising pattern and the inconsistent history provided by the parents, the nurse should suspect possible child abuse and take appropriate action by notifying the case manager in the clinic. The safety and well-being of the child should always be the top priority. Counseling for the family, warm baths, or recommending range of motion (ROM) exercises are not appropriate actions in this situation and may not address the underlying issue of potential child abuse.
2. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?
- A. normal
- B. elevated
- C. low
- D. unrelated to the pH
Correct answer: B
Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.
3. 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.
4. 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.
5. At what age will vision be 20/20 in children?
- A. 4 years old
- B. 5 years old
- C. 6 years old
- D. 7 years old
Correct answer: C
Rationale: The correct answer is 6 years old. At this age, children typically have the potential for 20/20 vision. This is considered the standard age for achieving optimal vision clarity. Choices A, B, and D are incorrect as they are not typically associated with the age at which children achieve 20/20 vision.
