Exam Cram NCLEX RN Practice Questions

1. Which of the following is a local sign of infection?

A. Swelling
B. Rapid pulse
C. Fever
D. High white blood count

Correct answer: A

Rationale: A local sign of infection refers to symptoms that are specific to the area of infection. Swelling, heat, pain, and redness near the infected site are examples of local signs. In the context of infection, swelling occurs due to an accumulation of fluid and immune cells at the site of infection. Rapid pulse, fever, and high white blood count are more systemic responses to infection and not specific local signs. Rapid pulse can indicate systemic distress or sepsis, fever is a systemic response to infection, and high white blood count is a laboratory finding that suggests an immune response but is not a direct sign of infection at a specific site.

2. What is the purpose of performing quality control?

A. Create a paper trail to show that the laboratory is compliant with OSHA standards for quality control.
B. Improve the odds that the results reported for any given test are as accurate and reliable as possible.
C. Be required by law to be part of a quality assurance program.
D. All of the above

Correct answer: B

Rationale: The primary purpose of performing quality control is to enhance the accuracy and reliability of test results. Quality controls are crucial for ensuring the reliability of each analyte tested. While quality control is not mandated by specific laws, accrediting bodies often require it to maintain accreditation. Creating a paper trail and legal requirements are not the primary objectives of quality control, making choices A and C incorrect. Therefore, the correct answer is to improve the accuracy and reliability of reported test results.

3. Which of the following statements best describes compartment syndrome?

A. An injury causes pain and tingling that starts in the buttock and travels down the leg.
B. An injury causes swelling within muscle tissue that leads to anoxia of nerves and muscles.
C. An injury causes permanent flexion of the interphalangeal joint, resulting in deformity.
D. An injury causes pain and swelling of the median plantar nerve.

Correct answer: B

Rationale: Compartment syndrome is characterized by swelling and increased pressure within a muscle compartment, leading to decreased blood flow and oxygen supply to nerves and muscles. This can result from various causes, such as trauma or the application of a cast after a fracture. If left untreated, compartment syndrome can lead to tissue necrosis. Choice A is incorrect as pain and tingling starting in the buttock and traveling down the leg are not specific features of compartment syndrome. Choice C is incorrect as permanent flexion of the interphalangeal joint is unrelated to compartment syndrome. Choice D is incorrect as pain and swelling of the median plantar nerve do not describe compartment syndrome.

4. A 27-year-old writer is admitted for the second time accompanied by his wife. He is demanding, arrogant, talks fast, and is hyperactive. Initially the nurse should plan this for a manic client:

A. Set realistic limits to the client's behavior
B. Repeat verbal instructions as often as needed
C. Allow the client to express feelings to relieve tension
D. Assign staff to be with the client at all times to help maintain control

Correct answer: A

Rationale: For a manic client who is hyperactive and may engage in injurious activities, setting realistic limits to the client's behavior is crucial to ensure safety. A quiet environment with firm and consistent limits helps in managing the client's behavior effectively. While repeating verbal instructions can be helpful due to the client's distractibility, it is not the priority compared to setting limits for safety concerns. Allowing the client to express feelings is important, but it should be done through non-destructive methods. Assigning staff to be with the client at all times is not realistic or feasible in the clinical setting and does not address the core issue of managing the client's behavior and ensuring safety.

5. You are creating a teaching plan for a patient with newly diagnosed migraine headaches. Which key item should NOT be included in the teaching plan?

A. Avoid foods that contain tyramine, such as alcohol and aged cheese.
B. Avoid drugs such as Tagamet, nitroglycerin, and Nifedipine.
C. Continue taking estrogen as prescribed by your physician.
D. A potential side effect of medications is rebound headache.

Correct answer: C

Rationale: The correct answer is C: Continue taking estrogen as prescribed by your physician. Medications such as estrogen supplements may actually trigger a migraine headache attack. Fluctuations in estrogen, such as before or during menstrual periods, pregnancy, and menopause, seem to trigger headaches in many women. Choices A and B are important to include in the teaching plan for a patient with migraines as avoiding foods containing tyramine and certain drugs can help prevent migraine triggers. Choice D is also relevant as it is essential for the patient to be aware of potential side effects of medications, including rebound headaches.
