The client diagnosed with Guillain-Barré syndrome is having difficulty breathing and is placed on a ventilator. Which situation warrants immediate intervention by the nurse?
- A. The ventilator rate is set at 14 breaths per minute.
- B. A manual resuscitation bag is at the client's bedside.
- C. The client's pulse oximeter reading is 85%.
- D. The ABG results are pH 7.4, PaO2 88, PaCO2 35, and HCO3 24.
Correct Answer: C
Rationale: A pulse oximeter reading of 85% indicates hypoxemia, requiring immediate intervention. Ventilator rate, resuscitation bag, and normal ABGs are appropriate.

The client is being evaluated to rule out myasthenia gravis and being administered the Tensilon (edrophonium chloride) test. Which response to the test indicates the client has myasthenia gravis?
- A. The client has no apparent change in the assessment data.
- B. There is increased amplitude of electrical stimulation in the muscle.
- C. The circulating acetylcholine receptor antibodies are decreased.
- D. The client shows a marked improvement of muscle strength.
Correct Answer: D
Rationale: The Tensilon test improves muscle strength in myasthenia gravis by inhibiting acetylcholinesterase. No change, electrical stimulation, or antibody levels are not diagnostic.
The nurse is admitting a client diagnosed with protein-calorie malnutrition secondary to AIDS. Which intervention should be the nurse's first intervention?
- A. Assess the client's body weight and ask what the client has been able to eat.
- B. Place in contact isolation and don a mask and gown before entering the room.
- C. Check the HCP's orders and determine what laboratory tests will be done.
- D. Teach the client about total parenteral nutrition and monitor the subclavian IV site.
Correct Answer: A
Rationale: Assessing weight and dietary intake provides baseline data for malnutrition management. Isolation is unnecessary, lab orders are secondary, and TPN teaching is premature.
The nurse and a licensed practical nurse are caring for clients in a rheumatologist's office. Which task can the nurse assign to the licensed practical nurse?
- A. Administer methotrexate, an antineoplastic medication, IV.
- B. Assess the lung sounds of a client with RA who is coughing.
- C. Demonstrate how to use clothing equipped with Velcro fasteners.
- D. Discuss methods of birth control compatible with treatment medications.
Correct Answer: C
Rationale: Demonstrating Velcro clothing is within LPN scope. Methotrexate administration, lung assessment, and birth control discussion require RN judgment.
Which statement by the client supports the diagnosis of Guillain-Barré syndrome?
- A. I just returned from a short trip to Japan.
- B. I had a really bad cold just a few weeks ago.
- C. I think one of the people I work with had this.
- D. I have been taking some herbs for more than a year.
Correct Answer: B
Rationale: A recent viral infection (e.g., cold) is a common trigger for Guillain-Barré syndrome. Travel, coworker illness, and herbs are less relevant.
The nurse is planning the care for a client diagnosed with RA. Which intervention should be implemented?
- A. Plan a strenuous exercise program.
- B. Order a mechanical soft diet.
- C. Maintain a keep-open IV.
- D. Obtain an order for a sedative.
Correct Answer: C
Rationale: A keep-open IV ensures access for RA medications (e.g., biologics). Strenuous exercise worsens joints, soft diets are unrelated, and sedatives are not routine.
