1. Which of the following is a common cause of acute kidney injury?
- A. Hypertension
- B. Dehydration
- C. Infection
- D. Hypotension
Correct answer: C
Rationale: Infection is a common cause of acute kidney injury because when the body fights an infection, it activates the immune response, leading to inflammation. This inflammatory response can affect the kidneys and impair their function. While hypertension (choice A) is a risk factor for chronic kidney disease, it is not a direct cause of acute kidney injury. Dehydration (choice B) can lead to prerenal acute kidney injury due to decreased blood flow to the kidneys, but infection is a more common cause of acute kidney injury. Hypotension (choice D) can contribute to prerenal acute kidney injury, but it is not a direct cause like infection.
2. A client tells the nurse, 'I have something very important to tell you if you promise not to tell.' The best response by the nurse is
- A. I must document and report any information.
- B. I can't make such a promise.
- C. That depends on what you tell me.
- D. I must report everything to the treatment team.
Correct answer: B
Rationale: The correct answer is B because the nurse cannot promise confidentiality in this context. It is essential to prioritize the safety and well-being of the client and others. Certain information, such as harm to oneself or others, must be reported to ensure appropriate interventions are taken. Choice A is incorrect because while documentation is important, confidentiality cannot be guaranteed in this situation. Choice C is incorrect as the nurse should not make promises that may conflict with their professional responsibilities. Choice D is incorrect as reporting everything to the treatment team without discretion may breach client confidentiality.
3. The nurse is caring for a 24-month-old toddler who has sensory sensitivity, difficulty engaging in social interactions, and has not yet spoken two-word phrases. Which assessment should the nurse administer?
- A. Peabody Picture Vocabulary Test
- B. The Modified Checklist for Autism in Toddlers (M-CHAT)
- C. Wechsler Preschool and Primary Scale of Intelligence
- D. Denver Developmental Screening Test
Correct answer: B
Rationale: The Modified Checklist for Autism in Toddlers (M-CHAT) is specifically designed to screen for autism spectrum disorders in young children. It is appropriate for this child, given the signs of social and communication delays. The Peabody Picture Vocabulary Test (Choice A) assesses receptive vocabulary and may not capture the social and communication aspects seen in autism. The Wechsler Preschool and Primary Scale of Intelligence (Choice C) measures cognitive ability and may not address the social and communication delays. The Denver Developmental Screening Test (Choice D) is a broad developmental assessment tool, but the M-CHAT is more specific to screening for autism in this case.
4. Isotretinoin is prescribed for a client with severe acne. Before the administration of this medication, the nurse anticipates that which laboratory test will be prescribed?
- A. Platelet count
- B. Triglyceride level
- C. Complete blood count
- D. White blood cell count
Correct answer: B
Rationale: Before administering Isotretinoin, it is important to check the client's triglyceride levels. Isotretinoin is known to elevate triglyceride levels, hence monitoring them before and periodically during treatment is essential to prevent potential adverse effects.
5. Before a client with renal failure undergoes hemodialysis, what should the nurse assess?
- A. Check the client's potassium levels
- B. Review the client's medication list
- C. Assess the client's peripheral pulses
- D. Monitor the client's urine output
Correct answer: A
Rationale: The correct answer is to check the client's potassium levels. Potassium levels are crucial to assess before hemodialysis in a client with renal failure because hyperkalemia (high potassium) is a common complication in these patients. Hemodialysis aims to remove excess potassium from the blood, making it essential to monitor potassium levels to determine the need for appropriate interventions. Reviewing the client's medication list (Choice B) is important for overall care but is not as directly relevant to the immediate concerns before hemodialysis. Assessing peripheral pulses (Choice C) and monitoring urine output (Choice D) are important aspects of nursing assessment but are not as directly related to the specific preparation needed before hemodialysis in a client with renal failure.
