LPN Fundamentals Questions Questions
Question 1 of 5
Embryos that are produced by in vitro fertilization can be screened for genetic disease. Outline the process of in vitro fertilization, including one example of a situation when it is used.
Correct Answer: C
Rationale: IVF involves ovarian stimulation, egg retrieval, sperm processing, fertilization, and embryo transfer. Need for genetic screening (C) is a situation, e.g., cystic fibrosis risk. Other options are valid but not the focus. C is correct. Rationale: IVF with preimplantation genetic diagnosis screens embryos for diseases, a key use, per reproductive medicine standards.
Question 2 of 5
The nurse is caring for a client with a traumatic brain injury who has an intracranial pressure (ICP) monitoring device in place. The ICP reading suddenly increases to $25 \mathrm{mmHg}$. Which action should the nurse take first?
Correct Answer: D
Rationale: ICP of 25 mmHg requires elevating HOB to 30 degrees (D) first to reduce pressure via venous drainage. Notification (A), pupils (B), or mannitol (C) follow. D is correct. Rationale: Immediate elevation lowers ICP non-invasively, a first-line action per neurocare protocols, buying time for further assessment.
Question 3 of 5
In the daily practice of nursing, nurses use critical thinking in:
Correct Answer: A
Rationale: Critical thinking in daily nursing practice is most evident when setting priorities, as it requires analyzing client needs, urgency, and resources to determine the order of care. This process involves evaluating multiple factors like a client's condition or time-sensitive tasks and making reasoned judgments, a hallmark of critical thinking. While it's used in every decision ideally, this isn't always practical or conscious for routine tasks like calling the pharmacy or checking supplies, which may rely more on habit or protocol. Prioritization, however, demands active synthesis of data, such as deciding to address a deteriorating patient before a stable one, ensuring efficient and safe care delivery. This application underscores its role in managing complex, dynamic workloads effectively.
Question 4 of 5
The nurse giving discharge instructions advises the client to get out of bed slowly and to get up in stages from lying to sitting to standing. The client understands that the reason for doing this is:
Correct Answer: A
Rationale: Advising a client to rise slowly in stages prevents falls by countering orthostatic hypotension, where blood pressure drops upon standing, risking dizziness. This technique allows gradual adjustment, especially post-illness or surgery. Improved circulation or oxygenation may occur, but fall prevention is the primary goal, not a warm-up. This instruction reduces injury risk, a critical discharge teaching point in nursing to ensure safety at home.
Question 5 of 5
Which of the following cells of the body are in almost constant mitosis?
Correct Answer: B
Rationale: Stomach cells undergo constant mitosis to replace lining lost to digestion, unlike nerve cells (rarely divide), muscle (slow turnover), or renal cells (less frequent). This informs nursing care, like monitoring gastric healing in ulcers.
