The nurse hangs an intravenous (IV) bag of 1000 mL of 5% dextrose in water (D5W) at 3 pm and sets the flow rate to infuse at 75 mL/hour. At 11 pm, the nurse should expect the fluid remaining in the IV bag to be at approximately which level?
Correct Answer: 400 mL
Rationale: In an 8-hour period, 600 mL would infuse if an IV is set to infuse at 75 mL/hour. Therefore, 400 mL would remain in the IV bag.

A client at risk for respiratory failure is receiving oxygen via nasal cannula at 6 L per minute. Arterial blood gas (ABG) results indicate pH 7.29, PcO2 49 mm Hg, Po2 58 mm Hg, and HCO3 18 mEq/L. What intervention should the nurse anticipate that the primary health care provider will prescribe for respiratory support for this client?
- A. Intubating for mechanical ventilation
- B. Keeping the oxygen at 6 L per minute via nasal cannula
- C. Lowering the oxygen to 4 L per minute via nasal cannula
- D. Adding a partial rebreather mask to the current prescription
Correct Answer: A
Rationale: If respiratory failure occurs and supplemental oxygen cannot maintain acceptable PaO2 and PaCO2 levels, endotracheal intubation and mechanical ventilation are necessary. The client is exhibiting respiratory acidosis, metabolic acidosis, and hypoxemia. Lowering or keeping the oxygen at the same liter flow will not improve the client's condition. A partial rebreather mask will raise CO2 levels even further.
A client is admitted after attempting suicide by ingesting a prescribed antipsychotic medication. What is the most important piece of information the nurse should obtain initially?
- A. Where and when the medication was ingested
- B. The name and amount of ingested medication
- C. If the client continues to have suicidal ideations
- D. If there is a history of previous suicidal attempts
Correct Answer: B
Rationale: In an emergency, lifesaving facts are obtained first. The name of and the amount of medication ingested is of utmost importance in treating this potentially life-threatening situation. The remaining data can be assessed once the client's physical condition is stabilized.
A client admitted to the hospital is suspected of having Guillain-Barré syndrome. Which assessment findings should the nurse identify as manifestations of this disorder? Select all that apply.
- A. Dysphagia
- B. Paresthesia
- C. Facial weakness
- D. Difficulty speaking
- E. Hyperactive deep tendon reflexes
- F. Descending symmetrical muscle weakness
Correct Answer: A,B,C,D
Rationale: Guillain-Barré syndrome is an acute autoimmune disorder characterized by varying degrees of motor weakness and paralysis. Motor manifestations include ascending symmetrical muscle weakness that leads to flaccid paralysis without muscle atrophy, decreased or absent deep tendon reflexes, respiratory compromise and respiratory failure, and loss of bladder and bowel control. Sensory manifestations include pain (cramping) and paresthesia. Cranial nerve manifestations include facial weakness, dysphagia, diplopia, and difficulty speaking. Autonomic manifestations include labile blood pressure, dysrhythmias, and tachycardia.
The nurse is caring for a 33-week pregnant client who has experienced a premature rupture of the membranes (PROM). Which interventions should the nurse expect to be part of the plan of care? Select all that apply.
- A. Perform frequent biophysical profiles.
- B. Monitor for elevated serum creatinine.
- C. Monitor for manifestations of infection.
- D. Teach the client how to count fetal movements.
- E. Use strict sterile technique for vaginal examinations.
- F. Inform the client about the need for tocolytic therapy.
Correct Answer: A,C,D,E
Rationale: Premature rupture of membranes (PROM) increases the risk of infection, preterm labor, and fetal compromise. Frequent biophysical profiles assess fetal well-being. Monitoring for manifestations of infection is critical due to the risk of chorioamnionitis. Teaching the client to count fetal movements helps monitor fetal activity and detect potential distress. Strict sterile technique for vaginal examinations minimizes infection risk. Monitoring serum creatinine is not directly related to PROM management. Tocolytic therapy may be considered but is not universally required unless preterm labor is confirmed.
The nurse has administered approximately half of a high-cleansing enema when the client reports pain and cramping. Which nursing action is appropriate?
- A. Reassuring the client that those sensations will subside
- B. Discontinuing the enema and notifying the primary health care provider
- C. Raising the enema bag so that the solution can be introduced quickly
- D. Clamping the tubing for 30 seconds and restarting the flow at a slower rate
Correct Answer: D
Rationale: The enema fluid should be administered slowly. If the client complains of pain or cramping, the flow is stopped for 30 seconds and restarted at a slower rate. Slow enema administration and stopping the flow temporarily, if necessary, will decrease the likelihood of intestinal spasm and premature ejection of the solution. The client's report of pain and cramping should not be ignored. The higher the solution container is held above the rectum, the faster the flow and the greater the force in the rectum. There is no need to discontinue the enema and notify the primary health care provider at this time.
