ATI Pharmacology 2023 III Questions
Question 1 of 5
A nurse is caring for a client who has a prescription for nifedipine. Which of the following findings should the nurse assess prior to administration of the medication?
Correct Answer: A
Rationale: The correct answer is A: Blood pressure. Nifedipine is a calcium channel blocker used to treat hypertension. Monitoring the client's blood pressure prior to administration is crucial as nifedipine can cause significant hypotension. Assessing respiratory rate, temperature, and oxygen saturation are important but not specific to nifedipine administration. Blood pressure is the most relevant parameter to monitor for this medication.
Question 2 of 5
A nurse is assessing a client who has received oxycodone. The nurse notes that the client's respiratory rate is 8/min. The nurse should identify that which of the following is the pathophysiology for the client's respiratory rate?
Correct Answer: C
Rationale:
Correct Answer: C - Oxycodone causes central nervous system depression.
Rationale: Oxycodone is an opioid analgesic that acts on the central nervous system to provide pain relief. One of the common side effects of opioids is respiratory depression, which can lead to a decreased respiratory rate. This occurs because opioids suppress the activity of the brainstem respiratory centers, leading to decreased drive to breathe and ultimately slowing down the respiratory rate.
Therefore, in this scenario, the client's low respiratory rate of 8/min is likely due to the central nervous system depression caused by oxycodone.
Summary of Incorrect
Choices:
A: Oxycodone blocking the sodium channel suspending nerve conduction is not the mechanism behind the respiratory depression seen with opioids.
B: Oxycodone promoting vasodilation of cranial arteries is not related to the respiratory depression caused by opioids.
D: Oxycodone inhibiting prostaglandin synthesis is not the mechanism responsible for the respiratory
Question 3 of 5
A nurse is assessing a client who received the measles, mumps, and rubella virus vaccine. Which of the following findings indicates an adverse reaction to the vaccination?
Correct Answer: B
Rationale: The correct answer is B: Petechiae. Petechiae are small red or purple spots on the skin caused by bleeding under the skin. This can indicate a serious adverse reaction to the vaccine, such as a bleeding disorder. Bradycardia (choice
A), tinnitus (choice
C), and blurred vision (choice
D) are not typical adverse reactions to the measles, mumps, and rubella vaccine. Bradycardia is a slow heart rate, tinnitus is ringing in the ears, and blurred vision can be a side effect of various medications but are not commonly associated with this vaccine.
Question 4 of 5
A nurse is caring for a client who received a dose of IV morphine for pain. Which of the following vital signs indicates the client is having an adverse reaction to the medication?
Correct Answer: D
Rationale: The correct answer is D. A respiratory rate of 10/min indicates respiratory depression, a common adverse reaction to morphine. Morphine can depress the respiratory center in the brain, leading to shallow breathing or apnea. This can result in hypoxia and potentially life-threatening complications. Blood pressure, temperature, and heart rate within normal ranges do not necessarily indicate adverse reactions to morphine. In summary, monitoring respiratory rate is crucial in detecting adverse reactions to morphine due to its potential for respiratory depression.
Question 5 of 5
A nurse is caring for a client who has received propofol during a colonoscopy. The nurse should monitor for which of the following as an adverse effect of the medication?
Correct Answer: B
Rationale: The correct answer is B: Decrease in respiratory rate. Propofol is a sedative-hypnotic medication that can cause respiratory depression as a side effect. This occurs due to its central nervous system depressant effects, leading to a decrease in the drive to breathe. Monitoring for a decrease in respiratory rate is crucial to prevent respiratory compromise or failure. The other options are incorrect because propofol does not typically cause an increase in heart rate (
A), bowel function (
C), or body temperature (
D) as its primary adverse effects.
