Question 1 of 5
Which of the following immunoglobulins is first produced during an acute infection?
Correct Answer: C
Rationale: The correct answer is C: IgM. During an acute infection, the body's initial response is rapid and non-specific, leading to the production of IgM antibodies first. IgM is the first immunoglobulin class produced in response to a new antigen, providing immediate protection. IgG is produced later in the immune response and is responsible for long-term immunity. IgE is involved in allergic reactions and parasitic infections, not typically the first response to infection. IgD is primarily found on the surface of B cells and its function is not well understood in the context of acute infections.
Question 2 of 5
Which of the following is an appropriate nursing intervention to prevent infection in patients with AIDS?
Correct Answer: C
Rationale: The correct answer is C. Wearing protective gear such as gown, mask, gloves, and goggles when entering the room is crucial to prevent infection in patients with AIDS. This intervention helps to minimize the risk of transmitting pathogens to the patient and vice versa. The protective gear acts as a barrier to prevent the spread of infectious agents. It also protects healthcare workers from exposure to potentially harmful pathogens. Prohibiting visitors who are severely immunodeficient (choice A) may be isolating for the patient and does not directly address preventing infection transmission. Prohibiting visitors with a cough (choice B) is important but does not cover all potential sources of infection. Ensuring protective barrier isolation precautions are in place (choice D) is a general statement and does not specify the practical steps needed to prevent infection transmission effectively.
Question 3 of 5
Which laboratory test value is elevated in clients who smoke and can’t be used as a general indicator of cancer?
Correct Answer: C
Rationale: The correct answer is C: Serum calcitonin level. Smoking can elevate serum calcitonin levels due to the effect of nicotine. However, an elevated serum calcitonin level is not a general indicator of cancer. Step 1: Understand that smoking can increase serum calcitonin levels. Step 2: Recognize that elevated serum calcitonin levels are not specific to cancer and can be influenced by other factors. Step 3: Differentiate between a marker that is specific to cancer (such as carcinoembryonic antigen) and one that can be affected by smoking but not necessarily indicative of cancer (serum calcitonin). Thus, while smoking can elevate serum calcitonin levels, it is not a reliable indicator of cancer.
Question 4 of 5
A client with end-stage acquired immunodeficiency syndrome (AIDS) has profound manifestations of Cryptosporidium infection caused by the protozoa. In planning the client’s care, the nurse should focus on his need for:
Correct Answer: C
Rationale: The correct answer is C: Fluid replacement. In end-stage AIDS with Cryptosporidium infection, the client experiences severe diarrhea leading to dehydration and electrolyte imbalances. Fluid replacement is crucial to prevent hypovolemia and maintain electrolyte balance. Adequate hydration supports renal function, prevents further complications, and aids in the elimination of the infectious agent. Pain management (A) may be needed for discomfort but is not the priority. Antiretroviral therapy (B) is essential for managing HIV but does not directly address the immediate issue of dehydration. High-calorie intake (D) is important for overall nutrition but does not address the urgent need for fluid replacement in this situation.
Question 5 of 5
The nurse is observing a client receiving antiplatelet therapy for adverse reactions. Antiplatelet drugs most commonly produce which hypersensitivity reaction?
Correct Answer: C
Rationale: The correct answer is C: Bronchospasm. Antiplatelet drugs commonly cause hypersensitivity reactions like bronchospasm due to their effects on platelet function. They can trigger an allergic response leading to bronchoconstriction. Difficulty hearing (A) is not a common hypersensitivity reaction to antiplatelet therapy. Confusion (B) is more commonly associated with central nervous system effects rather than hypersensitivity reactions. Agranulocytosis (D) is a severe drop in white blood cells and is not typically a hypersensitivity reaction to antiplatelet drugs.
