A magnetic resonance imaging (MRI) scan is prescribed for a client with a suspected brain tumor. Which prescription should the nurse anticipate will be prescribed for the client before the procedure?
- A. An opioid
- B. A sedative
- C. A corticosteroid
- D. An antihistamine
Correct Answer: B
Rationale: An MRI scan is a noninvasive diagnostic test that visualizes the body's tissues, structure, and blood flow. For an MRI, the client is positioned on a padded table and moved into a cylinder-shaped scanner. Relaxation techniques, an eye mask, and sedation are used before the procedure to reduce claustrophobic effects; however, because the client must remain very still during the scan, the nurse avoids oversedating the client to ensure client cooperation. There is no useful purpose for administering an opioid, corticosteroid, or antihistamine.

A client who experienced repeated pleural effusions from inoperable lung cancer is to undergo pleurodesis. What intervention should the nurse plan to implement after the primary health care provider injects the sclerosing agent through the chest tube to help assure the effectiveness of the procedure?
- A. Ambulate the client.
- B. Clamp the chest tube.
- C. Ask the client to cough and deep breathe.
- D. Ask the client to remain in a side-lying position.
Correct Answer: B
Rationale: After injection of the sclerosing agent, the chest tube is clamped to prevent the agent from draining back out of the pleural space. Depending on primary health care provider preference, a repositioning schedule is used to disperse the substance. Ambulation, coughing, and deep breathing have no specific purpose in the immediate period after injection.
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.
To ensure client safety, which assessment is most important for the nurse to make before advancing a client from liquid to solid food?
- A. Bowel sounds
- B. Chewing ability
- C. Current appetite
- D. Food preferences
Correct Answer: B
Rationale: The nurse needs to assess the client's chewing ability before advancing a client from liquid to solid food. It may be necessary to modify a client's diet to a soft or mechanical chopped diet if the client has difficulty chewing because of the risk of aspiration. Bowel sounds should be present before introducing any diet, including liquids. Appetite will affect the amount of food eaten, but not the type of diet prescribed. Food preferences should be ascertained on admission assessment.
A client receiving total parenteral nutrition (TPN) reports nausea, polydipsia, and polyuria. To determine the cause of the client's report, the nurse should assess which client data?
- A. Rectal temperature
- B. Last serum potassium
- C. Capillary blood glucose
- D. Serum blood urea nitrogen and creatinine
Correct Answer: C
Rationale: Clients receiving TPN are at risk for hyperglycemia related to the increased glucose load of the solution. The symptoms exhibited by the client are consistent with hyperglycemia. The nurse would need to assess the client's blood glucose level to verify these data. The other options would not provide any information that would correlate with the client's symptoms.
A client is brought into the emergency department after sustaining a possible closed head injury. Which assessment will the nurse perform first?
- A. Level of consciousness
- B. Pulse and blood pressure
- C. Respiratory rate and depth
- D. Ability to move extremities
Correct Answer: C
Rationale: The first action of the nurse is to ensure that the client has an adequate airway and respiratory status. In rapid sequence, the client's circulatory status is evaluated (option 2), followed by evaluation of the status of the cardiovascular and neurological systems.
