Nokea
The nurse is preparing to administer the fourth dose of IV vancomycin to a client. Which set of laboratory values would alert the nurse to hold the vancomycin and notify the health care provider?
- A. Vancomycin trough 10 mg/L (6.9 umol/L), creatinine 1.1 mg/dL (97.2 umol/L), BUN 6 mg/dL (2.1 mmol/L)
- B. Vancomycin trough 14 mg/L (9.7 umol/L), creatinine 1.2 mg/dL (106.1 umol/L), BUN 10 mg/dL (3.6 mmol/L)
- C. Vancomycin trough 18 mg/L (12.4 umol/L), creatinine 0.6 mg/dL (53 umol/L), BUN 18 mg/dL (6.4 mmol/L)
- D. Vancomycin trough 23 mg/L (15.9 umol/L), creatinine 1.5 mg/dL (132.6 umol/L), BUN 24 mg/dL (8.6 mmol/L)
Correct Answer: D
Rationale: A vancomycin trough of 23 mg/L is above the therapeutic range (10-20 mg/L), indicating potential toxicity. Elevated creatinine (1.5 mg/dL) suggests renal impairment, which increases the risk of vancomycin accumulation and nephrotoxicity.

An adult client is receiving oxygen at 6 L/min. The client asks the nurse why the oxygen is running through bubbling water. What should be included in the nurse's reply?
- A. The water cools the oxygen and makes it more comfortable.
- B. Oxygen is very drying to tissues; the water humidifies it.
- C. The water prevents fires when oxygen is in use.
- D. The water helps to prevent infections from developing in the tubing.
Correct Answer: B
Rationale: Bubbling water in oxygen delivery systems humidifies the oxygen, preventing mucosal drying. It doesn't cool oxygen, prevent fires, or reduce infections.
The nurse is caring for a 31-year-old gravida 2, para 1 woman who is in labor. The woman calls the nurse and says, 'My water has broken and I feel something between my legs.' The nurse looks and sees a loop of umbilical cord at the vaginal outlet. After signaling for help, what should the nurse do?
- A. Try to replace the cord with a sterile gloved hand
- B. Place the mother in knee-chest position
- C. Quickly apply manual pressure on the fundus
- D. Expect a rapid vaginal delivery
Correct Answer: B
Rationale: Knee-chest position relieves pressure on the prolapsed umbilical cord, maintaining fetal oxygenation until emergency delivery. Replacing the cord or pressing the fundus worsens the situation.

- A. Assess the condition of the IV site
- B. Check 2 client identifiers before administering medications

- D. Wash hands prior to administering medications
Correct Answer: C
Rationale: Ensuring medication compatibility prevents chemical interactions or precipitation in the IV line, which could harm the client or obstruct the catheter.
The nurse is caring for a client at 12 weeks gestation who has a rubella titer status of nonimmune. Which of the following actions should the nurse anticipate implementing?
- A. Administering measles-mumps-rubella (MMR) vaccine now
- B. Administering MMR vaccine immediately postpartum
- C. Administering MMR vaccine in the third trimester
- D. Informing the client that an MMR vaccine is not indicated
Correct Answer: B
Rationale: MMR is contraindicated during pregnancy due to risks to the fetus. Administering it postpartum ensures immunity for future pregnancies without harming the current pregnancy.
