Nokea
A client has been admitted to the labor and delivery unit in active labor. After assessing her, the RN notes that the client's fetus position is left occipital posterior. Which of the following statements best describes what this means to the labor process:
- A. Decreases the overall time of the labor process
- B. Prolongs the client's first stage of labor
- C. Decreases the time of the client's first stage of labor
- D. Prolongs the client's third stage of labor
Correct Answer: B
Rationale: The left occipital posterior position presents a larger fetal head diameter, increasing pressure on sacral nerves and prolonging the first stage of labor due to slower fetal descent.

A client has a tentative diagnosis of myasthenia gravis. The nurse recognizes that myasthenia gravis involves:
- A. Loss of the myelin sheath in portions of the brain and spinal cord
- B. An interruption in the transmission of impulses from nerve endings to muscles
- C. Progressive weakness and loss of sensation that begins in the lower extremities
- D. Loss of coordination and stiff 'cogwheel' rigidity
Correct Answer: B
Rationale: Myasthenia gravis is caused by autoantibodies blocking acetylcholine receptors, interrupting nerve impulse transmission to muscles, leading to weakness.
The client is admitted to the unit with a diagnosis of abruptio placenta. Which finding is most significant when assessing this client?
- A. Bright red vaginal bleeding
- B. Abdominal pain and rigidity
- C. Alteration in the fetal heart tones
- D. A soft,boggy uterus
Correct Answer: C
Rationale: Abruptio placenta involves placental separation which can compromise fetal oxygenation leading to abnormal fetal heart tones (e.g. bradycardia or late decelerations). This is the most significant finding as it indicates fetal distress. Bleeding pain and rigidity are relevant but secondary to fetal well-being.
The client is admitted with a diagnosis of preterm labor. Which symptom is most characteristic?
- A. Uterine contractions
- B. Fetal macrosomia
- C. Maternal fever
- D. Painless vaginal bleeding
Correct Answer: A
Rationale: Uterine contractions (regular frequent) are the hallmark of preterm labor occurring before 37 weeks. Fetal macrosomia maternal fever and painless bleeding are not characteristic.
The RN on the oncology unit is preparing to mix and administer amphoteracin B (Fungizone) to a client. Which action is contraindicated for administering this drug IV?
- A. Mix the drug with normal saline solution.
- B. Administer the drug over 4-6 hours.
- C. Hydrate with IV fluids two hours before the infusion is scheduled to begin.
- D. Premedicate the client with ordered acetaminophen (Tylenol) and diphenhydramine (Benadryl).
Correct Answer: A
Rationale: Amphotericin B should be mixed with D5W, not normal saline, due to stability issues. Slow infusion (B), hydration (C), and premedication (D) are standard practices.
What is the appropriate nursing action for a child with increased intracranial pressure?
- A. Head of bed elevated 45 degrees with child's head maintained in a neutral position
- B. Child lying flat
- C. Head turned to side
- D. Frequent visitation for stimulation
Correct Answer: A
Rationale: Elevating the head of the bed to 45 degrees with a neutral head position promotes venous drainage, reducing intracranial pressure.
