1. Which of the following is not true of mitosis?
- A. Mitosis produces daughter cells
- B. Mitosis has five main stages
- C. Mitosis can only be done by haploids
- D. Following mitosis, daughter cells are identical to parent cells
Correct answer: C
Rationale: The correct answer is C. Mitosis occurs in diploid cells and involves stages that result in the production of two identical daughter cells. Haploids do not undergo mitosis, as mitosis is a process specific to diploid cells. Choice A is true as mitosis does produce daughter cells. Choice B is incorrect as mitosis typically consists of four main stages: prophase, metaphase, anaphase, and telophase. Choice D is true, as one of the main outcomes of mitosis is the production of daughter cells that are genetically identical to the parent cell.
2. What is the correct procedure for performing an ophthalmoscopic examination on a client's right retina?
- A. Instruct the client to focus on a distant object behind the examiner and not move their eyes during the exam.
- B. Set the ophthalmoscope on the plus 2 to 3 lens and hold it in front of the examiner's right eye.
- C. From a distance of 12 to 15 inches and slightly to the side, shine the light into the client's pupil.
- D. For optimal visualization, keep the ophthalmoscope at least 3 inches from the client's eye.
Correct answer: C
Rationale: During an ophthalmoscopic examination, the client should focus on a distant object behind the examiner to dilate the pupil, and the examiner should stand at a distance of 12-15 inches away and slightly to the side. This angle allows for better visualization of the retina. Holding the ophthalmoscope firmly against the examiner's face and shining the light into the client's pupil helps examine the retina effectively. Choice A is incorrect because the client should look at a distant object, not the examiner's nose. Choice B is incorrect as the ophthalmoscope should be directed towards the client's eye, not the examiner's eye. Choice D is incorrect because keeping the ophthalmoscope at least 3 inches away may not provide an optimal view of the retina.
3. The letter 'T' in the Acronym 'GATHER' denotes:
- A. Ask the client about themselves - particular needs, obstetric and medical history
- B. Tell the client about modern FP methods available, and discuss each in detail
- C. Help the client choose a method and repeat information regarding the chosen method if necessary
- D. Explain how to use the method - what, where, when, and how
Correct answer: B
Rationale: The correct answer is B: 'Tell the client about modern FP methods available, and discuss each in detail.' In the GATHER acronym, 'T' stands for providing information about modern family planning methods to the client and having a detailed discussion. Choices A, C, and D are incorrect because they do not accurately represent the 'T' component in the GATHER approach. Choice A focuses more on gathering information from the client, choice C is about helping the client choose a method, and choice D is about explaining how to use the method, none of which align with the 'T' in GATHER.
4. The nurse is preparing a discharge teaching plan for a liver transplant client. Which instruction is most important to include in this plan?
- A. Ensure daily follow-up with the healthcare provider
- B. Take immunosuppressant medications as prescribed
- C. Avoid crowds for the first two months after surgery
- D. Return to work in three months
Correct answer: B
Rationale: The most critical instruction to include in the discharge teaching plan for a liver transplant client is to take immunosuppressant medications as prescribed. This is vital to prevent organ rejection and ensure the success of the transplant. While ensuring daily follow-up with the healthcare provider is important for monitoring progress, avoiding crowds for the first two months after surgery helps reduce the risk of infections but is not as crucial as medication adherence. Returning to work in three months is a consideration but not the most important aspect immediately post-transplant.
5. Which task could be safely delegated by the nurse to an unlicensed assistive personnel (UAP)?
- A. Accompanying a client who self-administers insulin
- B. Cleansing and dressing a small decubitus ulcer
- C. Monitoring a client's response to passive range of motion exercises
- D. Applying and caring for a client's rectal pouch
Correct answer: D
Rationale: The correct answer is D because tasks like applying and caring for a client's rectal pouch are within the UAP's scope of practice, as they do not require clinical judgment. Choices A, B, and C involve more complex assessments or interventions that require clinical judgment and should be performed by licensed nursing staff.
