1. An 8-year-old child who weighs 60 pounds receives an order for Polycilin (Ampicillin) suspension 25 mg/kg/day divided into a dose every 8 hours. The medication is labeled '125 mg/5 ml'. How many ml should the nurse administer per dose every 8 hours?
- A. 5
- B. 10
- C. 15
- D. 20
Correct answer: A
Rationale: Calculate the daily dose first: 60 pounds x 25 mg/kg = 1500 mg/day. Divide by 3 doses = 500 mg/dose. Convert to mL: (500 mg / 125 mg) x 5 ml = 20 ml. However, the question asks for the dose per administration every 8 hours, which is 1/3 of the daily dose. So, the correct calculation should be (20 ml / 3) = 6.67 ml, which rounds to 5 ml. Therefore, the correct answer is 5 ml. Choice B (10 ml) is incorrect because it doesn't consider the frequency of dosing. Choice C (15 ml) is incorrect as it overestimates the dose. Choice D (20 ml) is incorrect as it represents the total daily dose, not the dose per administration every 8 hours.
2. An adult male was diagnosed with stage IV lung cancer three weeks ago. His wife approaches the nurse and asks how she will know that her husband's death is imminent because their two adult children want to be there when he dies. What is the best response by the nurse?
- A. Explain that the client will start to lose consciousness and his body systems will slow down
- B. Reassure the spouse that the healthcare provider will let her know when to call the children
- C. Offer to discuss the client’s health status with each of the adult children
- D. Gather information on how long it will take for the children to arrive
Correct answer: A
Rationale: The best response for the nurse is to explain that the client will start to lose consciousness and his body systems will slow down. Providing information on the signs of impending death helps the family prepare emotionally and allows them to be present at the appropriate time. Choice B is incorrect because it does not empower the family with the knowledge they seek. Choice C is incorrect as discussing the client’s health status individually with the adult children may not address the wife's immediate concern. Choice D is incorrect as the priority should be on preparing the family for the signs of imminent death rather than focusing on logistical details.
3. Four clients arrive on the labor and delivery unit at the same time. Which client should the nurse assess first?
- A. A 38-week primigravida who reports contractions occurring every 10 minutes
- B. A 39-week primigravida with a biophysical profile score of 5 out of 8
- C. A 41-week multigravida who is scheduled for induction of labor today
- D. A 36-week multigravida with a prescription for serial blood pressure
Correct answer: B
Rationale: The correct answer is B. A biophysical profile score of 5 out of 8 indicates potential fetal distress, necessitating immediate assessment to ensure the well-being of the fetus. The other options, while important, do not suggest an immediate threat to the fetus' health. The 38-week primigravida with contractions every 10 minutes may be in early labor, the 41-week multigravida scheduled for induction can be assessed after addressing the immediate concern, and the 36-week multigravida with serial blood pressure can be assessed after ensuring the client with potential fetal distress is stabilized.
4. The nurse is assigned to care for four surgical clients. After receiving report, which client should the nurse see first?
- A. An older client receiving packed RBCs on the third day postoperatively for colon resection
- B. An older client with continuous bladder irrigation who is 2 days postoperatively for bladder surgery
- C. An adult one day postoperatively from laparoscopic cholecystectomy requesting pain medication
- D. An adult in Buck’s traction, scheduled for hip arthroplasty within the next 12 hours
Correct answer: B
Rationale: The correct answer is B because the client with continuous bladder irrigation post-bladder surgery is at risk for complications like infection or bleeding. This client requires immediate attention to assess for any signs of complications such as urinary retention, hemorrhage, or infection. Choices A, C, and D have less urgent needs compared to a client with continuous bladder irrigation, which requires priority assessment.
5. When deciding whether to join a nursing strike called after collective bargaining efforts have failed, which factor is most important for the nurse to consider?
- A. Nurse Practice Act of the State
- B. The role of nurses as client advocates
- C. Standards of clinical nursing practice
- D. Personal value system
Correct answer: B
Rationale: The correct answer is B. The role of nurses as client advocates is crucial when considering the impact of a strike on patient care. Nurses have a responsibility to advocate for their patients' well-being at all times. Choices A, C, and D, although important, are not the most critical factor to consider in this situation. The Nurse Practice Act of the State is essential for guiding nursing practice, standards of clinical nursing practice ensure quality care, and personal values are important; however, the primary focus during a strike should be on the role of nurses as client advocates.
