ATI Capstone Pharmacology Assessment 2 Questions
Question 1 of 5
Drug action that increase body activity
Correct Answer: A
Rationale: Stimulants are drugs that increase the body's activity levels. They work on the central nervous system to enhance alertness, attention, and energy. Examples of stimulants include caffeine, amphetamines, and nicotine. Stimulants can increase heart rate, blood pressure, and metabolism, leading to heightened physical and mental activity.
Question 2 of 5
If a bacteria were susceptible to both penicillin and erythromycin, then it would not be appropriate to treat the patients with both antibiotics at the same time because:
Correct Answer: A
Rationale: Penicillin is inactivated by erythromycin. Penicillin is a beta-lactam antibiotic which acts by inhibiting cell wall synthesis in bacteria. However, erythromycin is a macrolide antibiotic which can inactivate beta-lactam antibiotics like penicillin. When given together, erythromycin can inactivate penicillin, reducing its efficacy and potentially leading to treatment failure. Therefore, it is not appropriate to use both penicillin and erythromycin simultaneously to treat a bacterial infection.
Question 3 of 5
A patient undergoing chemotherapy for breast cancer asks why she is not receiving trastuzumab like her sister. Which response by the nurse is correct?
Correct Answer: D
Rationale: Trastuzumab is a targeted therapy used specifically for HER2-positive breast cancer. If the patient's cancer cells do not overexpress the HER2 receptor, trastuzumab will not be effective. The decision to use targeted therapy is based on the molecular characteristics of the tumor, not the patient's age, insurance coverage, or estrogen receptor status. The nurse should explain that targeted therapies are tailored to the specific biology of the cancer, and trastuzumab is only appropriate for HER2-positive tumors.
Question 4 of 5
Upon preparing to administer activated charcoal by mouth to treat a patient who took an overdose of aspirin and several unknown drugs, the nurse notes that the patient has become very somnolent and eyes open only to a noxious stimulus. Which action by the nurse is most appropriate at this point?
Correct Answer: A
Rationale: The patient's decreased level of consciousness (somnolence and only responding to noxious stimuli) indicates a potential deterioration in their condition, possibly due to the overdose. Activated charcoal is contraindicated in patients with an altered mental status due to the risk of aspiration. The nurse should immediately consult the nurse practitioner to reassess the patient's condition and determine the appropriate intervention, such as securing the airway or considering alternative treatments.
Question 5 of 5
For the patient who is taking nalbuphine, what should the nurse do? (Select all that apply.)
Correct Answer: D
Rationale: Nalbuphine is an opioid agonist-antagonist used for pain management. Like other opioids, it can cause respiratory depression, so monitoring respirations is critical. Bradycardia is another potential side effect that patients should report. Administering nalbuphine undiluted is not standard practice, as it can increase the risk of adverse reactions. Excessive urine output is not associated with nalbuphine use. Therefore, the nurse should focus on monitoring respirations and educating the patient to report bradycardia.
