PN ATI Capstone Pharmacology 1 Quiz
1. A healthcare professional is teaching a client about the use of methotrexate. Which of the following should be included?
- A. It is a pain reliever
- B. Monitor for signs of infection
- C. It can be taken without food
- D. It is safe to use during pregnancy
Correct answer: B
Rationale: The correct answer is B: 'Monitor for signs of infection.' Methotrexate can suppress the immune system, making the client more susceptible to infections. Educating the client to monitor for signs of infection is crucial for early detection and management. Choice A is incorrect because methotrexate is not a pain reliever; it is commonly used to treat conditions like cancer, rheumatoid arthritis, and psoriasis. Choice C is incorrect because methotrexate is usually recommended to be taken with food to reduce gastrointestinal side effects. Choice D is incorrect because methotrexate is known to be harmful during pregnancy and should not be used by pregnant individuals as it can cause birth defects.
2. A nurse is caring for a client who is receiving oxytocin to augment labor. The client has an intrauterine pressure catheter and an internal fetal scalp electrode for monitoring. Which of the following is an indication that the nurse should discontinue the infusion?
- A. Contraction frequency every 3 minutes
- B. Contraction duration of 100 seconds
- C. Fetal heart rate with moderate variability
- D. Fetal heart rate of 118/min
Correct answer: B
Rationale: A contraction duration of 100 seconds indicates potential uterine hyperstimulation, which can lead to fetal distress and decreased uterine perfusion. Prolonged contractions may reduce oxygen supply to the fetus, putting it at risk. Discontinuing the oxytocin infusion is crucial to prevent adverse effects on both the mother and the fetus. The other options do not raise immediate concerns that would necessitate discontinuing the oxytocin infusion. Contraction frequency every 3 minutes is within a normal range. Fetal heart rate with moderate variability and a rate of 118/min are both reassuring signs of fetal well-being.
3. A client at 38 weeks of gestation with a diagnosis of preeclampsia has the following findings. Which of the following should the nurse identify as inconsistent with preeclampsia?
- A. 1+ pitting sacral edema
- B. 3+ protein in the urine
- C. Blood pressure 148/98 mm Hg
- D. Deep tendon reflexes of +1
Correct answer: D
Rationale: Deep tendon reflexes of +1 are inconsistent with preeclampsia. Preeclampsia typically presents with hyperreflexia, not diminished reflexes. Diminished reflexes may indicate other neurological conditions, thus making this finding inconsistent with preeclampsia. Choices A, B, and C are consistent with preeclampsia. Pitting sacral edema, protein in the urine, and elevated blood pressure are common findings in preeclampsia due to fluid retention, kidney involvement, and hypertension associated with the condition.
4. The lining of the stomach and intestine is protected from self-digestion by:
- A. pepsinogen.
- B. bile.
- C. mucus.
- D. fat.
Correct answer: C
Rationale: The correct answer is C: mucus. Mucus forms a protective barrier that prevents the stomach and intestine from digesting themselves. Pepsinogen (choice A) is an inactive form of pepsin, a digestive enzyme, and does not protect the stomach lining. Bile (choice B) aids in the digestion and absorption of fats but does not protect the stomach lining. Fat (choice D) is a nutrient and energy source; it does not play a role in protecting the stomach and intestine from self-digestion.
5. A client is receiving furosemide. Which of the following laboratory values should the nurse monitor?
- A. Sodium
- B. Potassium
- C. Calcium
- D. Magnesium
Correct answer: B
Rationale: The correct answer is B: Potassium. Furosemide is a loop diuretic that can cause potassium depletion through increased urinary excretion. Monitoring potassium levels is crucial to prevent hypokalemia, which can lead to cardiac dysrhythmias, muscle weakness, and other serious complications. Monitoring sodium, calcium, and magnesium levels is not typically associated with furosemide therapy, making choices A, C, and D incorrect.
