Which of the following drugs inhibit bacterial beta-lactamase?

goldenseal

ceftriaxone (Rocephin)

penicillin

Zosyn (piperacillin/tazobactam)

Answer and Explanation

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 A

Explanation

A. Ginger root:

Ginger root is well-known for its anti-nausea and anti-inflammatory properties. It has been used for centuries to alleviate motion sickness, nausea, and vomiting. Ginger works by helping to calm the stomach and alleviate gastrointestinal discomfort. Therefore, ginger root is a suitable herbal supplement for controlling nausea associated with motion sickness.

B. Garlic:

Garlic is not typically used for controlling nausea. While garlic has various health benefits, including cardiovascular and immune support, it is not known for its anti-nausea properties.

C. Kava:

Kava is an herbal supplement used for its anxiolytic and sedative effects. It is not commonly used for controlling nausea and may not be effective for alleviating symptoms of motion sickness.

D. Valerian:

Valerian is an herb primarily used for its sedative and anxiolytic properties. It is not commonly used for controlling nausea and would not be an appropriate choice for alleviating symptoms of motion sickness.

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.
