The nurse should teach a patient to observe which side effects when taking ampicillin.
Reddened tongue and gums.
Digit numbness and tingling.
Bruising and petechiae.
Skin rash and loose stools.
The Correct Answer is D
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.

Correct Answer is A
Explanation
A. "Tetracycline inhibits protein synthesis."
Explanation: Tetracycline antibiotics interfere with bacterial protein synthesis by binding to the bacterial ribosomes. This binding prevents the attachment of transfer RNA (tRNA) to the messenger RNA (mRNA) complex, effectively inhibiting the production of proteins that are crucial for bacterial growth and replication.
B. "Tetracycline blocks RNA synthesis."
Explanation: This statement is incorrect. Tetracycline primarily affects protein synthesis, not RNA synthesis. It doesn't block the creation of RNA molecules in bacteria.
C. "Tetracycline degrades the bacterial cell wall."
Explanation: This statement is incorrect. Tetracycline antibiotics do not target bacterial cell walls. Agents like penicillins and cephalosporins are examples of antibiotics that disrupt bacterial cell walls.
D. "Tetracycline binds to magnesium ions."
Explanation: This statement is incorrect. Tetracycline does bind to certain metal ions, but it's not primarily through magnesium ions. The binding to bacterial ribosomes is a key mechanism of action for tetracyclines.
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.
