ATI Capstone Pharmacology Assessment 2 Questions
Question 1 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.
Question 2 of 5
The basic metric unit for the measurement of volume :
Correct Answer: C
Rationale: The basic metric unit for the measurement of volume is the liter. Although all the other options are also units used for measuring volume, the liter is considered the basic metric unit. It is often used for measuring larger volumes of liquids or gases. The other options are subunits of a liter:
Question 3 of 5
An adolescent client will receive Depo-Provera as a method of birth control. She asks the nurse how long the drug will be effective. What is the best response by the nurse?
Correct Answer: D
Rationale: Depo-Provera lasts 3 months , inhibiting ovulation via progestin. Two months underestimates, six months and one year overestimate. D provides accurate timing, ensuring adherence, making it the best response.
Question 4 of 5
Thiopental is used as an anesthetic agent during surgery to repair a small-bowel obstruction in a 78-year-old man. Approximately 1 day after his surgery, toxicology studies still reveal some thiopental present in the bloodstream. What is the most likely explanation for this finding?
Correct Answer: C
Rationale: Thiopental, a barbiturate, persists 24 hours post-surgery. Physiologic metabolism is correct-its lipophilicity causes redistribution to fat, with slow hepatic metabolism, normal in the elderly. Hepatitis or insufficiency lacks evidence. Renal failure doesn't primarily clear it. Trauma (E) is unrelated. This reflects thiopental's pharmacokinetics, not pathology.
Question 5 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.
