The nurse is caring for a client diagnosed with beta lactam resistant bacteria. The nurse anticipates administering which broad spectrum antibiotic?
Ancef (ciprofloxacin)
Merrem (meropenem)
Flagyl (metronidazole)
Zosyn (piperacillin tazobactam)
The Correct Answer is B
Choice A reason: Ancef (ciprofloxacin) is not the correct answer for the nurse who anticipates administering a broad-spectrum antibiotic to a client diagnosed with a beta lactam resistant bacteria. Ancef is the brand name of cefazolin, which is a firstgeneration cephalosporin, a subclass of beta lactam antibiotics. Cefazolin is effective against gram-positive bacteria, but has limited activity against gram negative bacteria and anaerobes. Cefazolin is also susceptible to beta-lactamase enzymes, which are produced by some bacteria to degrade beta lactam antibiotics and confer resistance. The nurse should avoid using Ancef or any other beta lactam antibiotic for a client with a beta lactam resistant bacteria.
Choice B reason: Merrem (meropenem) is the correct answer for the nurse who anticipates administering a broad-spectrum antibiotic to a client diagnosed with a beta lactam resistant bacteria. Merrem is the brand name of meropenem, which is a carbapenem, a subclass of beta lactam antibiotics. Meropenem is effective against a wide range of bacteria, including gram-positive, gram negative, and anaerobic bacteria. Meropenem is also resistant to most beta-lactamase enzymes, except for metallo-beta-lactamase’s, which are rare and can be detected by laboratory tests. The nurse should consider using Merrem or another carbapenem for a client with a beta lactam resistant bacteria, unless they have a history of allergy or intolerance to beta lactam antibiotics .
Choice C reason: Flagyl (metronidazole) is not the correct answer for the nurse who anticipates administering a broad spectrum antibiotic to a client diagnosed with a beta lactam resistant bacteria. Flagyl is the brand name of metronidazole, which is a nitroimidazole antibiotic. Metronidazole is effective against anaerobic bacteria and some protozoa, but has no activity against aerobic bacteria. Metronidazole is not a beta lactam antibiotic, and it is not affected by beta-lactamase enzymes. However, metronidazole is not a broad spectrum antibiotic, and it is not suitable for treating infections caused by aerobic bacteria, which are more common than anaerobic bacteria. The nurse should use Flagyl only for specific indications, such as bacterial vaginosis, trichomoniasis, or Clostridioides difficile infection .
Choice D reason: Zosyn (piperacillin tazobactam) is not the correct answer for the nurse who anticipates administering a broad-spectrum antibiotic to a client diagnosed with a beta lactam resistant bacterium. Zosyn is the brand name of piperacillin tazobactam, which is a combination of penicillin, a subclass of beta lactam antibiotics, and a beta-lactamase inhibitor. Piperacillin is effective against some gram-positive and gram-negative bacteria, but it is susceptible to beta-lactamase enzymes. Tazobactam is a compound that binds to and inhibits some beta-lactamase enzymes, thereby protecting piperacillin from degradation and extending its spectrum of activity. However, piperacillin tazobactam is not effective against all types of beta-lactamase enzymes, especially those that are encoded by plasmids and can be transferred between bacteria. The nurse should not use Zosyn or any other beta lactam/beta-lactamase inhibitor combination for a client with a beta lactam resistant bacterium unless the specific type of beta-lactamase is known and susceptible to the inhibitor.

Correct Answer is B
Explanation
Choice A reason: "If my breathing begins to feel tight, I will use the cromolyn immediately." is an incorrect statement for the client who has asthma and new prescriptions for Albuterol and Atrovent, both by nebulizer. Cromolyn is a medication that prevents the release of inflammatory substances from the mast cells in the airways, which can cause bronchospasm and asthma symptoms¹. Cromolyn is not a rescue medication, but a maintenance medication that should be used regularly to prevent asthma attacks. The client should use Albuterol, a short acting beta agonist, to relieve acute bronchospasm and wheezing.
Choice B reason: "I will be sure to take the albuterol before taking the Atrovent." is a correct statement for the client who has asthma and new prescriptions for Albuterol and Atrovent, both by nebulizer. Albuterol is a medication that relaxes the muscles in the airways and increases the airflow to the lungs, which can improve the breathing and reduce the wheezing in patients with asthma. Atrovent is a medication that blocks the action of acetylcholine, a neurotransmitter that causes bronchoconstriction and mucus secretion, which can worsen the asthma symptoms. The client should take the Albuterol before the Atrovent, as this will allow the Albuterol to open the airways and enhance the absorption and effectiveness of the Atrovent.
Choice C reason: "I will administer the medications 10 minutes apart." is an unnecessary statement for the client who has asthma and new prescriptions for Albuterol and Atrovent, both by nebulizer. The client does not need to wait 10 minutes between the administration of the two medications, as they can be given together in the same nebulizer chamber. This will save time and simplify the treatment regimen for the client. The client should follow the instructions on the medication label or the prescriber's order regarding the dosage and frequency of the nebulizer treatments.
Choice D reason: "I will use both medications immediately after exercising." is an inappropriate statement for the client who has asthma and new prescriptions for Albuterol and Atrovent, both by nebulizer. The client should not use both medications immediately after exercising, as this may not prevent or relieve exercise induced bronchospasm, a condition that causes the airways to narrow during or after physical activity. The client should use Albuterol, a short acting beta agonist, before exercising, as this will prevent the bronchospasm and allow the client to exercise safely and comfortably. The client should use Atrovent, an anticholinergic, as prescribed, usually twice a day, to control the chronic symptoms of asthma.
Correct Answer is D
Explanation
Choice A reason: This is incorrect. Taking antacids does not protect the stomach from the irritation caused by spicy foods. Antacids only reduce the acidity of the stomach contents, but they do not heal the ulcer or prevent further damage.
Choice B reason: This is incorrect. Taking antacids does not affect the digestion of carbohydrates or any other nutrients. Antacids only act on stomach acid, not on the enzymes that break down food.
Choice C reason: This is incorrect. Taking antacids does not stop the stomach from producing acid. Antacids only react with the acid that is already present in the stomach, but they do not inhibit the secretion of acid by the stomach cells.
Choice D reason: This is correct. Taking antacids will help neutralize the acid that is already in the stomach, which can relieve the pain and discomfort caused by the ulcer. Antacids can also form a protective coating over the ulcer, which can help it heal faster.
