Which of the following drugs inhibit bacterial beta-lactamase?
goldenseal
ceftriaxone (Rocephin)
penicillin
Zosyn (piperacillin/tazobactam)
The Correct Answer is D
A.Goldenseal:
Goldenseal is a plant commonly used in herbal medicine, but it is not a drug that specifically inhibits bacterial beta-lactamase. While goldenseal may have antimicrobial properties, it is not typically used as a beta-lactamase inhibitor in the treatment of bacterial infections.
B. Ceftriaxone (Rocephin):
Ceftriaxone is a third-generation cephalosporin antibiotic. While it is an effective antibiotic for treating a wide range of bacterial infections, it does not have beta-lactamase inhibitor properties. Instead, ceftriaxone is susceptible to degradation by beta-lactamase enzymes produced by certain bacteria.
C. Penicillin:
Penicillin is one of the earliest discovered and most widely used beta-lactam antibiotics. However, many bacteria have developed resistance to penicillin by producing beta-lactamase enzymes. Penicillin itself does not inhibit beta-lactamase; instead, it is often combined with beta-lactamase inhibitors to enhance its effectiveness against beta-lactamase-producing bacteria.
D. Zosyn (piperacillin/tazobactam):
Zosyn is a combination antibiotic containing piperacillin, a broad-spectrum penicillin antibiotic, and tazobactam, a beta-lactamase inhibitor. Tazobactam inhibits the action of beta-lactamase enzymes produced by bacteria, allowing piperacillin to exert its antibacterial effects without being degraded by beta-lactamase. Therefore, Zosyn is the correct answer as it contains a drug that inhibits bacterial beta-lactamase.

Correct Answer is ["125"]
Explanation
To calculate the rate at which the IV pump should be set to deliver 3,000 mL of intravenous fluids over 24 hours, you would divide the total volume (3,000 mL) by the total time (24 hours):
Rate (mL/hr) = Total volume (mL) / Total time (hours)
Rate = 3,000 mL / 24 hours
Rate ≈ 125 mL/hr
Rounding to the nearest whole number, the IV pump should be set to deliver approximately 125 mL/hr.
Correct Answer is A
Explanation
A. Keep the serum drug level within the therapeutic margin:
This is the correct goal of monitoring peak and trough levels during antibacterial therapy. The therapeutic margin refers to the range of drug concentrations in the bloodstream that achieves optimal therapeutic effects while avoiding toxicity. By monitoring peak and trough levels, healthcare providers can adjust the dosing regimen to maintain drug levels within this therapeutic margin.
B. Increase the therapeutic effect of the drug by gradually decreasing the drug dose:
This statement is incorrect. Monitoring peak and trough levels is not about increasing the therapeutic effect of the drug by gradually decreasing the drug dose. Instead, it's about ensuring that the drug levels are maintained within the appropriate therapeutic range to achieve optimal efficacy without causing adverse effects.
C. Provide maximum physical comfort to the patient:
Monitoring peak and trough levels is not primarily aimed at providing physical comfort to the patient. While optimizing drug therapy can contribute to improved clinical outcomes and patient well-being, the goal of monitoring these levels is specifically related to achieving therapeutic drug concentrations.
D. Treat the main disorder with no psychological distress to the patient:
This statement is unrelated to the goal of monitoring peak and trough levels during antibacterial therapy. While psychological distress may be a consideration in patient care, the primary goal of monitoring drug levels is to ensure therapeutic efficacy and safety.
