A nurse is reinforcing teaching with a client who reports motion sickness about using an herbal supplement. The nurse should identify that the client can use which of the following herbal supplements to help control nausea?

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.

A. Changes in mental status:

Changes in mental status are not typically associated with ototoxicity caused by gentamicin. Mental status changes may indicate other systemic effects or adverse reactions, but they are not specific to ototoxicity.

B. Complaints that he is unable to hear the television:

This complaint is highly indicative of ototoxicity. Hearing loss, particularly high-frequency hearing loss, is a common symptom of ototoxicity caused by drugs like gentamicin. Difficulty hearing sounds such as the television, especially at typical volume levels, suggests a potential problem with hearing function.

C. An increase in the BUN and creatinine:

An increase in blood urea nitrogen (BUN) and creatinine levels may indicate kidney damage, which can occur as a result of nephrotoxicity associated with gentamicin use. While nephrotoxicity is a known adverse effect of gentamicin, it is not specific to ototoxicity.

D. Tingling of the extremities:

Tingling of the extremities is not typically associated with ototoxicity caused by gentamicin. This symptom may suggest other neurological or systemic effects but is not specific to ototoxicity.
