A 65-year-old female is diagnosed with metastatic breast cancer. Which of the following cells would be produced in large quantities to eliminate the tumor cells?
Neutrophils
Eosinophils
Platelets
Macrophages
The Correct Answer is D
A. Neutrophils: Neutrophils are a type of white blood cell that plays a key role in the immune system's response to infections, particularly bacterial infections. They are not primarily involved in eliminating cancer cells.
B. Eosinophils: Eosinophils are another type of white blood cell. They are important in the immune response to parasites and are also involved in allergic reactions. While they have a role in the immune system, they are not the primary cells involved in eliminating cancer cells.
C. Platelets: Platelets, also known as thrombocytes, are not cells but rather small cell fragments. They are essential for blood clotting and do not directly participate in the immune response against cancer cells.
D. Macrophages: Macrophages are a type of white blood cell that are involved in the immune system's defense against cancer. They are phagocytes, which means they engulf and digest cellular debris, foreign substances, and cancer cells. Macrophages play a crucial role in the body's immune surveillance and response against cancer.

Correct Answer is C
Explanation
A. 8:00 AM: This time is too early to draw a trough level for a medication administered at 10:00 AM. The trough level should be drawn just before the next dose is given to get the lowest concentration in the bloodstream.
B. 11:00 AM: This time is after the scheduled dose of vancomycin at 10:00 AM. Waiting until 11:00 AM would not provide an accurate trough level because the patient has already received the medication.
C. 9:00 AM: This is the correct time to obtain the patient's blood sample. It is one hour before the scheduled dose of vancomycin at 10:00 AM. Drawing the trough level at this time ensures it reflects the lowest concentration of the drug in the bloodstream.
D. 12:00 noon: This time is after the scheduled dose of vancomycin at 10:00 AM. Waiting until noon would not provide an accurate trough level because the patient has already received the medication.
Correct Answer is D
Explanation
A. Reddened tongue and gums: This side effect is not typically associated with ampicillin. However, certain medications or medical conditions can cause changes in oral tissues, leading to redness in the tongue and gums.
B. Digit numbness and tingling: Ampicillin does not commonly cause numbness and tingling in the fingers and toes. These symptoms can be associated with neurological issues or circulatory problems.
C. Bruising and petechiae: These symptoms can indicate bleeding disorders or low platelet count and are not usually caused by ampicillin. It's essential to investigate further if a patient experiences unexplained bruising or petechiae.
D. Skin rash and loose stools: Skin rash is a known side effect of penicillin-type antibiotics, including ampicillin. Loose stools or diarrhea can also occur due to disruption of the gut flora caused by the antibiotic. Patients should be aware of these possibilities and report any severe or persistent symptoms to their healthcare provider.
