1. What is the classification of Ondansetron?
- A. Antihypertensive
- B. Antiarrhythmic
- C. Antiemetic
- D. Antiulcer agent
Correct answer: C
Rationale: Ondansetron is classified as an antiemetic. It is commonly used to prevent nausea and vomiting, especially in patients undergoing chemotherapy or surgery. Choice A, Antihypertensive, is incorrect as Ondansetron is not used to treat high blood pressure. Choice B, Antiarrhythmic, is incorrect as Ondansetron is not used to manage heart rhythm abnormalities. Choice D, Antiulcer agent, is incorrect as Ondansetron is not primarily indicated for treating ulcers.
2. A nurse is preparing to administer medication to a client by nasogastric tube. What should the nurse do first?
- A. Administer the medication without further assessment.
- B. Check the tube placement before administering any medication.
- C. Administer the medication in liquid form only.
- D. Administer half the dosage as a precaution.
Correct answer: B
Rationale: The correct answer is B: Check the tube placement before administering any medication. Before administering medication through a nasogastric tube, the nurse must first verify the tube's correct placement to ensure the medication reaches the stomach and to prevent complications such as aspiration. Options A, C, and D are incorrect because administering medication without confirming proper tube placement can lead to serious consequences for the client.
3. A client is 4 hours postpartum. Which of the following interventions should be implemented to prevent postpartum hemorrhage?
- A. Monitor for signs of infection.
- B. Massage the uterus every 4 hours.
- C. Apply ice packs to the perineum.
- D. Administer methylergonovine IM.
Correct answer: D
Rationale: Administering methylergonovine intramuscularly helps contract the uterus, reducing the risk of postpartum hemorrhage. Monitoring for signs of infection (Choice A) is important but not directly related to preventing postpartum hemorrhage. Uterine massage (Choice B) is beneficial to prevent uterine atony, but methylergonovine is a more specific intervention to prevent hemorrhage. Applying ice packs to the perineum (Choice C) is helpful for perineal pain and swelling, not for preventing postpartum hemorrhage.
4. Urinary tract anomalies are frequently associated with what irregularities in fetal development?
- A. Myelomeningocele
- B. Cardiovascular anomalies
- C. Malformed or low-set ears
- D. Defects in lower extremities
Correct answer: C
Rationale: Malformed or low-set ears are often associated with congenital urinary tract anomalies, as both the ears and kidneys develop around the same time during fetal growth. Myelomeningocele, cardiovascular anomalies, and lower extremity defects are less commonly associated with UT anomalies.
5. A healthcare professional is reviewing the laboratory results of a client who has chronic kidney disease. Which of the following findings should the healthcare professional report to the provider?
- A. Serum potassium 4.5 mEq/L
- B. Serum calcium 9.2 mg/dL
- C. Serum creatinine 2.5 mg/dL
- D. Serum albumin 3.5 g/dL
Correct answer: C
Rationale: Elevated serum creatinine levels indicate impaired kidney function. As kidney disease progresses, the kidneys are less able to filter waste products, leading to an increase in creatinine levels. Therefore, a high serum creatinine level of 2.5 mg/dL should be reported to the provider for further evaluation and management. Choices A, B, and D are within normal ranges and do not directly signify worsening kidney function in this context.
