Question 1 of 5
A nurse is caring for a client who reports muscle spasms after receiving haloperidol. Which of the following medications should the nurse expect to administer?
Correct Answer: B
Rationale: The correct answer is B: Benztropine. Benztropine is an anticholinergic medication commonly used to treat extrapyramidal symptoms such as muscle spasms caused by antipsychotic drugs like haloperidol. It works by blocking the action of acetylcholine in the brain, helping to alleviate muscle spasms. Metoprolol (
A) is a beta-blocker used for hypertension, not muscle spasms. Oxycodone (
C) is an opioid for pain relief, not muscle spasms. Risperidone (
D) is another antipsychotic but not typically used to treat muscle spasms.
Question 2 of 5
A nurse is reinforcing teaching with a client who has motion sickness and a new prescription for a transdermal patch of scopolamine. The nurse should instruct the client to monitor for which of the following adverse effects?
Correct Answer: D
Rationale: The correct answer is D: Drowsiness. Scopolamine is an anticholinergic medication commonly used to treat motion sickness. One of the common side effects of anticholinergics is drowsiness. This occurs due to the central nervous system depressant effects of the medication. Monitoring for drowsiness is important as it can impact the client's ability to drive or operate machinery safely.
A: Diarrhea is not a common side effect of scopolamine.
B: Bruising is not a common side effect of scopolamine.
C: Jaundice is not a common side effect of scopolamine.
Question 3 of 5
A nurse is caring for a client who has cystic fibrosis. The client is taking pancrelipase and has a new onset of steatorrhea. Which of the following statements should the nurse make?
Correct Answer: D
Rationale:
Correct
Answer: D
Rationale: Pancrelipase helps with digestion of fats. Taking it with food allows for proper mixing with food in the stomach, aiding in digestion. This is crucial for absorption of nutrients in cystic fibrosis. Other choices are incorrect because:
A: Steatorrhea is not an adverse reaction but a sign of inadequate fat digestion.
B: Increasing fat intake can worsen steatorrhea in cystic fibrosis.
C: Chewing the medication does not affect fat digestion.
In summary, taking pancrelipase with food optimizes its effectiveness in aiding fat digestion and absorption in cystic fibrosis.
Question 4 of 5
A nurse in a provider's office is collecting data from a client who continues to have a migraine headache after taking sumatriptan orally 2 hr ago. Which of the following findings is the priority for the nurse to report?
Correct Answer: B
Rationale: The correct answer is B: Hypertension. The priority for the nurse to report is hypertension because sumatriptan can potentially cause an increase in blood pressure as a side effect. Hypertension is a serious condition that can lead to complications if not managed promptly.
A: Tingling sensation is a common side effect of sumatriptan and may not be immediately concerning.
C: Flushing is also a common side effect of sumatriptan and is usually not a priority.
D: Dizziness is a less severe side effect compared to hypertension and can often be managed with rest.
Question 5 of 5
A nurse is preparing to administer 1 L of IV fluid over 6 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 167 mL/hr
Rationale:
To calculate mL/hr for IV fluid administration, divide the total volume (1 L = 1000 mL) by the total time in hours (6 hr).
Therefore, 1000 mL / 6 hr = 166.67 mL/hr, rounded to 167 mL/hr. This rate ensures the patient receives the correct volume over the specified time. Other choices are incorrect because they do not follow the correct calculation method or may not deliver the required volume within the specified time frame.
