Which of the following medications should be held 24-48 hours prior to an electroencephalogram (EEG)?
- A. Lasix (furosemide)
- B. Cardizem (diltiazem)
- C. Lanoxin (digoxin)
- D. Dilantin (phenytoin)
Correct Answer: D
Rationale: Anticonvulsants like Dilantin should be held 24-48 hours before an EEG to prevent interference with the test results. Medications such as tranquilizers, barbiturates, and other sedatives should also be avoided. Lasix, Cardizem, and Lanoxin do not belong to these categories and are not known to interfere with EEG results.

Which of the following neurological disorders is characterized by writhing, twisting movements of the face and limbs?
- A. epilepsy
- B. Parkinson's
- C. multiple sclerosis
- D. Huntington's chorea
Correct Answer: D
Rationale: Huntington's chorea is characterized by writhing, twisting movements of the face and limbs, known as chorea. This disorder is caused by a genetic mutation affecting specific brain cells. Epilepsy presents with seizures, Parkinson's with tremors and rigidity, and multiple sclerosis with central nervous system issues. The specific description of writhing and twisting movements aligns with Huntington's chorea, making it the correct answer. Choices A, B, and C are incorrect as they describe different neurological disorders with distinct symptoms that do not match the writhing, twisting movements characteristic of Huntington's chorea.
What can happen if a restraint is attached to a side rail or other movable part of the bed?
- A. Do nothing to the client.
- B. Injure the client if the rail or bed is moved.
- C. Help the client stay in the bed without falling out.
- D. Help the client with better posture.
Correct Answer: B
Rationale: Attaching a restraint to a movable part of the bed can lead to client injury if that part of the bed is moved before releasing restraints. This could result in the client getting caught or trapped, possibly causing harm. Choices C and D are incorrect because attaching restraints to movable parts of the bed is not intended to help the client stay in bed or improve posture; rather, it poses a risk of injury. Choice A is incorrect as it does not address the potential harm associated with using restraints on movable parts of the bed.
A client turns her ankle. She is diagnosed as having a Pulled Ligament. This should be documented as a:
- A. sprain.
- B. strain.
- C. subluxation.
- D. dislocation.
Correct Answer: B
Rationale: A sprain is the correct term for the excessive stretching of a ligament, which is what happens when a ligament is pulled. A strain involves muscle tissue. Subluxation refers to a partial dislocation, and dislocation is a complete displacement of bones in a joint. In this case, since it's a pulled ligament, the most appropriate term is a sprain.
For a client requiring total oral care, it is important for the nurse to:
- A. assemble all equipment, assist the client to a semi-Fowler's position, and place a towel on his chest.
- B. place the client in Fowler's position, prepare the equipment, and instruct the client what to do.
- C. assemble all equipment, place the client in a side-lying position, and place a towel under his chin.
- D. use gloves and clean the client's mouth, including the tongue.
Correct Answer: C
Rationale: To provide total oral care to a client, the nurse should first assemble all necessary equipment. Placing the client in a side-lying position helps fluids to easily flow out or pool in the side of the mouth for suctioning, thus preventing aspiration. Additionally, placing a towel under the client's chin and a curved basin against the chin helps to maintain cleanliness during the procedure. Choice A is incorrect because the client should be placed in a side-lying position, not a semi-Fowler's position which is used for respiratory issues. Choice B is incorrect as it does not emphasize the importance of proper positioning for effective oral care. Choice D is incorrect as it oversimplifies the procedure by focusing only on cleaning the mouth without considering the importance of positioning and preparation.
A client is told that his test is positive, but in fact, the client does not have the disease tested for. Which type of false report is this an example of?
- A. positive
- B. false positive
- C. negative
- D. false negative
Correct Answer: B
Rationale: The correct answer is 'false positive.' A false-positive result occurs when a test result is labeled positive in error, when the actual result is negative. In this scenario, the client received a positive test result incorrectly, as he does not have the disease being tested for. Choice A ('positive') is too vague and does not specify that the result was incorrect. Choice C ('negative') is the opposite of what happened in the scenario. Choice D ('false negative') refers to a situation where a test result is labeled negative incorrectly, which is not the case in this scenario.
