Nursing Elites

1. A client is having blood tests and has an elevated lymphocyte level. Based on knowledge of cellular components, what does the nurse know about these cells?

• A. Contain histamine and provide protection during allergic reactions
• B. Are involved in phagocytosis
• C. Provide protection and immunity against foreign substances
• D. Carry hemoglobin and oxygen to body tissues

Correct answer: C

Rationale: Lymphocytes are a type of white blood cells that play a crucial role in supporting the body's immune system. They are responsible for producing substances that protect the body against infections and foreign substances that could potentially harm the client. Lymphocytes consist of two main types: T cells, which are produced in the thymus, and B cells, which are produced in the lymphatic tissue. Choice A is incorrect because histamine is mainly associated with basophils and mast cells, not lymphocytes. Choice B is incorrect as phagocytosis is a function of other white blood cells such as neutrophils and macrophages. Choice D is also incorrect as carrying hemoglobin and oxygen is a function of red blood cells, not lymphocytes.

2. Which information given by a 70-year-old patient during a health history indicates to the nurse that the patient should be screened for hepatitis C?

• A. The patient had a blood transfusion in 2005
• B. The patient used IV drugs about 20 years ago
• C. The patient frequently eats in fast-food restaurants
• D. The patient traveled to a country with poor sanitation

Correct answer: B

Rationale: The correct answer is 'The patient used IV drugs about 20 years ago.' Any patient with a history of IV drug use should be tested for hepatitis C due to the increased risk of transmission through sharing needles. Blood transfusions given after 1992, when an antibody test for hepatitis C became available, do not pose a risk for hepatitis C. Hepatitis C is not spread by the oral-fecal route, so contaminated food or traveling to countries with poor sanitation are not direct risk factors for hepatitis C.

3. Which of these devices is considered a protective device, rather than a restraint?

• A. A mitten on the hands to prevent scratching
• B. A mitten on the hands to prevent the person from pulling their IV out
• C. A side rail to prevent the patient from falling
• D. A soft wrist restraint to prevent the patient from pulling their IV tubing

Correct answer: A

Rationale: A mitten on the hands to prevent scratching is considered a protective device because its primary purpose is to protect the patient from harming themselves by scratching. It does not restrict the patient's movement. Choice B, a mitten on the hands to prevent the person from pulling their IV out, is considered a restraint as it limits the patient's movement. Choice C, a side rail to prevent the patient from falling, is also a protective device as it aims to keep the patient safe by providing support and preventing falls. Choice D, a soft wrist restraint to prevent the patient from pulling their IV tubing, is a type of restraint as it restricts the patient's movement to prevent them from interfering with medical equipment.

4. Choose the BEST answer. To ensure adequate protection for legal issues, offices should maintain patients' charts for:

• A. 10 years
• B. Forever
• C. Until the age of majority
• D. 2 years after the patient was last seen in the office

Correct answer: B

Rationale: The correct answer is 'Forever.' Maintaining patients' charts indefinitely ensures comprehensive legal protection by having all relevant information available in case of litigation or if patient history needs to be referenced in the future. Choice A, '10 years,' may not be sufficient to cover the entire period within which legal issues may arise. Choice C, 'Until the age of majority,' is not ideal as legal matters may extend beyond this age limit. Choice D, '2 years after the patient was last seen in the office,' is inadequate as legal actions can occur beyond this timeframe, necessitating the need for long-term retention of patient charts.

5. Mary T. was admitted to a nursing home on May 1st. On July 4th, she was diagnosed with a skin infection. This infection is considered a ________________ infection.

• A. nosocomial
• B. systemic
• C. resident flora
• D. resident aura

Correct answer: A

Rationale: The correct answer is 'nosocomial.' A nosocomial infection is defined as one that is not present upon admission to a healthcare facility but instead occurs during the patient's stay. In this case, since Mary was diagnosed with a skin infection after being admitted to the nursing home, it is considered a nosocomial infection. Nosocomial infections are a significant concern in healthcare settings, and infection control measures are in place to prevent their spread. Choices B, C, and D are incorrect. 'Systemic' refers to a condition affecting the entire body, not specific to a healthcare setting. 'Resident flora' and 'resident aura' are not commonly used terms in healthcare and do not relate to infections acquired in healthcare facilities.
