1. Which of the following white blood cells is the smallest and can be involved in humoral immunity?

• A. Lymphocyte
• B. Monocyte
• C. Basophil
• D. Erythrocyte

Correct answer: A

Rationale: The correct answer is 'Lymphocyte.' Lymphocytes are the smallest type of white blood cells and play a crucial role in humoral immunity by producing antibodies. Monocytes are actually the largest white blood cells and are involved in phagocytosis rather than humoral immunity. Basophils are a type of granulocyte involved in allergic reactions, and erythrocytes are red blood cells responsible for oxygen transport, not part of the immune system.

2. What is the highest priority for post ECT care?

• A. Observe for confusion
• B. Monitor respiratory status
• C. Reorient to time, place, and person
• D. Document the client's response to the treatment

Correct answer: B

Rationale: The highest priority for post ECT care is to monitor respiratory status. This is crucial because a life-threatening side effect of ECT is respiratory arrest. While observing for confusion and reorienting the client are important aspects of post ECT care, they are not as critical as ensuring the client's respiratory status is stable. Documenting the client's response to treatment is also important for maintaining accurate medical records, but it is not the highest priority immediately post ECT.

3. A systemic sign of infection is ______________.

• A. swelling
• B. redness
• C. heat
• D. a lack of appetite

Correct answer: D

Rationale: The correct answer is 'a lack of appetite.' When a person experiences a systemic infection, they may exhibit signs that affect the entire body. A lack of appetite is a common systemic sign of infection, along with other symptoms like rapid pulse, fever, and an elevated white blood cell count. Swelling, redness, and heat are more indicative of localized inflammation or infection, rather than systemic involvement.

4. When a blood pressure cuff is too wide for a client's arm, what type of reading might this blood pressure cuff produce?

• A. A normal reading
• B. An abnormally low reading
• C. An abnormally high reading
• D. A fluctuating reading

Correct answer: B

Rationale: When a blood pressure cuff is too wide for a client's arm, it may produce an abnormally low blood pressure reading. This occurs because the oversized cuff can lead to an underestimation of blood pressure. It is essential to ensure that the cuff fits appropriately to obtain an accurate reading. An abnormally high reading (Choice C) is less likely with an oversized cuff, as it generally leads to lower readings. A normal reading (Choice A) is unlikely due to the inaccuracies caused by the oversized cuff. A fluctuating reading (Choice D) is not a typical result of using a cuff that is too wide; instead, it usually leads to consistently low readings.

5. 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.
