What pathophysiological events occur sequentially in the development of atherosclerosis?
- A. Foam cells release growth factors.
- B. Smooth muscle grows over fatty streaks creating fibrous plaques.
- C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
- D. Arterial endothelium injury causes inflammation.
Correct Answer: D
Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.

What does the nurse's signature on the client's surgical consent form signify?
- A. The client voluntarily grants permission for the procedure to be done
- B. The client is competent to sign the consent without impairment of judgment
- C. The client understands the risks and benefits associated with the procedure
- D. The client has signed the form freely and voluntarily
Correct Answer: A
Rationale: The nurse's signature on a surgical consent form signifies that the client voluntarily grants permission for the procedure to be done. This is the correct answer because the nurse's signature does not imply the client's competence, understanding of risks and benefits, or that the client signed the form freely and voluntarily. The nurse's role is to verify that the client has made an informed decision and is providing consent for the procedure.
The nurse leading a medical-surgical unit care team assigns client care to a PN and a UAP. Which task should the nurse delegate to the UAP?
- A. Assess a client's pain level post-surgery
- B. Turn and reposition a client with a total hip replacement
- C. Administer a dose of insulin per sliding scale
- D. Change a postoperative dressing
Correct Answer: B
Rationale: Turning and repositioning a client is within the scope of practice of a UAP. This task helps prevent pressure ulcers and assists in maintaining the client's comfort and mobility. Assessing pain level post-surgery requires clinical judgment and interpretation, making it appropriate for a PN or RN. Administering medication like insulin involves critical thinking and potential adjustments based on the client's condition, which is the responsibility of a licensed nurse. Changing postoperative dressings involves wound assessment, infection control, and knowledge of aseptic techniques, tasks that fall under the purview of a PN or RN.
A client with peripheral artery disease reports leg cramps while walking. What intervention should the nurse recommend?
- A. Encourage the client to rest immediately when cramping occurs.
- B. Recommend that the client increase their intake of potassium-rich foods.
- C. Advise the client to take a short break, then continue walking.
- D. Recommend that the client avoid walking altogether to prevent cramps.
Correct Answer: C
Rationale: For clients with peripheral artery disease, advising the client to take a short break when leg cramps occur and then continue walking is the appropriate intervention. This approach, known as interval walking, helps manage pain from intermittent claudication and improves circulation over time. Choice A is incorrect because immediate rest may not be necessary, and encouraging the client to resume walking after a short break is more beneficial. Choice B is incorrect since increasing potassium-rich foods may not directly address the underlying issue of peripheral artery disease causing cramps. Choice D is incorrect as avoiding walking altogether can lead to further deconditioning and worsen symptoms over time.
A nurse from the maternity unit is floated to the critical care unit because of staff shortage on the evening shift. Which client would be appropriate to assign to this nurse?
- A. A client with a Dopamine drip IV with vital signs monitored every 5 minutes
- B. A client with a myocardial infarction that is free from pain and dysrhythmias
- C. A client with a tracheotomy of 24 hours in some respiratory distress
- D. A client with a pacemaker inserted this morning with intermittent capture
Correct Answer: B
Rationale: In this scenario, it is more appropriate to assign a stable client, such as the one with a myocardial infarction who is free from pain and dysrhythmias, to a nurse who lacks specialized critical care experience. This client's condition is relatively stable and does not require immediate critical interventions. Choices A, C, and D involve clients with more complex and critical conditions that would be better managed by a nurse with specialized critical care training. Choice A involves a client on a Dopamine drip with frequent vital sign monitoring, Choice C has a client with a tracheotomy in respiratory distress, and Choice D describes a client with a pacemaker experiencing intermittent capture, all of which require a higher level of critical care expertise.
An S3 heart sound is auscultated in a client in her third trimester of pregnancy. What intervention should the nurse take?
- A. Perform a 12-lead electrocardiogram
- B. Document in the client's record
- C. Notify the healthcare provider immediately
- D. Assess for signs of heart failure
Correct Answer: B
Rationale: An S3 heart sound is often a normal finding in pregnant women due to increased blood volume and cardiac output. The nurse should document the finding as part of the routine assessment unless accompanied by other abnormal symptoms. Performing a 12-lead electrocardiogram (Choice A) is unnecessary for a normal S3 heart sound in pregnancy. Notifying the healthcare provider immediately (Choice C) is premature and may lead to unnecessary interventions. Assessing for signs of heart failure (Choice D) is not indicated as an isolated S3 heart sound is typically benign in pregnancy.
