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 D
Explanation
Choice A reason: Dextromethorphan (Robitussin) is not the correct medication for a patient with a productive cough. Dextromethorphan is a cough suppressant that works by acting on the brain to reduce the cough reflex. Dextromethorphan is used for a dry, nonproductive cough that is caused by irritation or inflammation. Dextromethorphan is not effective for a productive cough that produces mucus, and it may even be harmful by preventing the clearance of secretions from the lungs.
Choice B reason: Fluticasone (Flonase) is not the correct medication for a patient with a productive cough. Fluticasone is a corticosteroid that works by reducing inflammation and swelling in the nasal passages. Fluticasone is used for allergic rhinitis, which is a condition that causes sneezing, itching, and runny nose due to an allergic reaction. Fluticasone is not effective for a productive cough that produces mucus, and it may even worsen it by suppressing the immune system and increasing the risk of infection.
Choice C reason: Pseudoephedrine (Sudafed) is not the correct medication for a patient with a productive cough. Pseudoephedrine is a decongestant that works by constricting the blood vessels in the nasal passages and sinuses. Pseudoephedrine is used for nasal congestion, which is a condition that causes stuffy nose and difficulty breathing due to swelling of the mucous membranes. Pseudoephedrine is not effective for a productive cough that produces mucus, and it may even cause side effects such as increased blood pressure, insomnia, and anxiety.
Choice D reason: Guaifenesin (Mucinex) is the correct medication for a patient with a productive cough. Guaifenesin is an expectorant that works by thinning and loosening the mucus in the chest and throat. Guaifenesin is used for a productive cough that produces mucus, as it helps the cough to be more effective and clear the airways. Guaifenesin is generally safe and well tolerated, but it may cause some minor side effects such as nausea, vomiting, and headache.
Correct Answer is B
Explanation
Choice A reason: "I am not ready to eat lunch yet." is not a concerning statement for the patient who has completed their Albuterol nebulizer treatment. 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 asthma¹. Albuterol does not affect the appetite or the digestion directly, but it may cause some side effects such as nausea, vomiting, or dry mouth, which may reduce the desire to eat. The nurse should respect the patient's preference and offer them food later when they are ready.
Choice B reason: "It feels like my heart is racing." is a concerning statement for the patient who has completed their Albuterol nebulizer treatment. Albuterol is a medication that relaxes the muscles in the airways and increases the airflow to the lungs, but it also stimulates the beta receptors in the heart, which can increase the heart rate and the blood pressure¹. This can cause side effects such as palpitations, chest pain, or arrhythmias, especially in patients with underlying heart conditions or those who take other medications that affect the heart. The nurse should monitor the patient's vital signs, report the finding to the prescriber, and prepare to administer interventions such as betablockers or calcium channel blockers to lower the heart rate and prevent complications.
Choice C reason: "It is easier to breathe now." is not a concerning statement for the patient who has completed their Albuterol nebulizer treatment. 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 asthma¹. This is the expected and desired outcome of the Albuterol nebulizer treatment, which indicates that the medication is effective and the patient is responding well. The nurse should document the patient's response and continue to assess the patient's respiratory status and oxygen saturation.
Choice D reason: "I can breathe better now." is not a concerning statement for the patient who has completed their Albuterol nebulizer treatment. 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 asthma¹. This is the expected and desired outcome of the Albuterol nebulizer treatment, which indicates that the medication is effective and the patient is responding well. The nurse should document the patient's response and continue to assess the patient's respiratory status and oxygen saturation.
