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. A patient born in 1955 had hepatitis A infection 1 year ago. According to Centers for Disease Control and Prevention (CDC) guidelines, which action should the nurse include in care when the patient is seen for a routine annual physical exam?

A. Start the hepatitis B immunization series.
B. Teach the patient about hepatitis A immune globulin.
C. Ask whether the patient has been screened for hepatitis C.
D. Test for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM).

Correct answer: C

Rationale: The correct action for the nurse to include in care when the patient is seen for a routine annual physical exam, according to CDC guidelines, is to ask whether the patient has been screened for hepatitis C. CDC guidelines recommend screening patients born between 1945 and 1965 for hepatitis C due to the high prevalence of undiagnosed cases in this age group. Starting the hepatitis B immunization series is not necessary as the patient already had hepatitis A infection. Teaching the patient about hepatitis A immune globulin is not indicated in this scenario. Testing for anti-hepatitis-A virus immune globulin M (anti-HAV-IgM) is not needed as the patient has already had hepatitis A.

3. A client has entered disseminated intravascular coagulation (DIC) after becoming extremely ill after surgery. Which of the following laboratory findings would the nurse expect to see with this client?

A. Elevated fibrinogen level
B. Prolonged PT
C. Elevated platelet count
D. Depressed d-dimer level

Correct answer: B

Rationale: In disseminated intravascular coagulation (DIC), a client experiences widespread clotting throughout the body, leading to the depletion of clotting factors and platelets. A prolonged prothrombin time (PT) is a common finding in DIC. The PT measures the extrinsic pathway of the clotting cascade and reflects how quickly blood can clot. In DIC, the consumption of clotting factors results in a prolonged PT, indicating impaired clotting ability. Elevated fibrinogen levels (Choice A) are typically seen in the early stages of DIC due to the body's attempt to compensate for clot breakdown. Elevated platelet count (Choice C) is not a typical finding in DIC as platelets are consumed during the widespread clotting. A depressed d-dimer level (Choice D) is also not expected in DIC as d-dimer levels are elevated due to the breakdown of fibrin clots. Therefore, the correct answer is a prolonged PT.

4. How can the dangers associated with wandering in Alzheimer's disease patients be prevented?

A. Bed alarms
B. Chair alarms
C. Door alarms
D. All of the above

Correct answer: D

Rationale: The correct answer is 'All of the above.' Bed alarms, chair alarms, and door alarms are all effective measures to prevent the dangers associated with wandering in Alzheimer's disease patients. These alarms can alert caregivers when a patient tries to leave a designated area, helping to keep them safe. It is crucial to respond promptly to these alarms to ensure the patient's safety. Choices A, B, and C are incorrect individually as each type of alarm plays a vital role in a comprehensive wandering prevention strategy.

5. Which of the following is an example of a living will?

A. A client's son has been appointed to make his healthcare decisions if he becomes incapacitated
B. A client has designated which of his children will receive his home and property before he dies
C. A client has instructions that he does not want to be resuscitated through chest compressions if his heart stops beating
D. A client designates what type of burial or cremation services he would want after his death

Correct answer: C

Rationale: A living will is a type of advanced directive that a client develops to stipulate his preferences for healthcare in the event that he is unable to do so. This includes specific instructions about medical treatments in certain situations. Choice C is the correct answer as it reflects a scenario where the client has clearly outlined their preference regarding resuscitation through chest compressions. Choices A, B, and D do not pertain to a living will. Choice A involves a healthcare proxy or agent, choice B involves a will or estate planning, and choice D involves funeral or burial arrangements, which are not part of a living will.
