1. 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.

2. How does cancer affect pain tolerance in elderly clients?

A. Remain constant.
B. Decrease.
C. Increase.
D. Cancer has no impact on pain tolerance in elderly clients.

Correct answer: B

Rationale: Pain tolerance in elderly clients with cancer is likely to decrease due to factors such as diminished adaptative capacity, increased physical discomfort, and the psychological impact of the disease. Cancer is known to cause various physical and emotional stressors that can lower the pain threshold, leading to a decrease in pain tolerance. Choices A, C, and D are incorrect because cancer and its associated effects typically result in a decrease in pain tolerance rather than remaining constant, increasing, or having no impact.

3. A nurse who recently learned she is pregnant has just received client assignments for the day. Which client assignment should the nurse question as being inappropriate?

A. A client with metastatic cancer who is receiving a continuous infusion of intravenous morphine sulfate
B. A client with a solid-sealed cervical radiation implant
C. A client with diarrhea for whom enteric precautions are in effect
D. A client for whom contact precautions have been implemented and who requires frequent wound irrigations

Correct answer: B

Rationale: The correct answer is a client with a solid-sealed cervical radiation implant. Brachytherapy involves the implantation of a sealed radiation source within the targeted tumor tissue. A client with such an implant emits radiation as long as it is in place. Pregnant nurses should not care for clients with solid-sealed radiation implants due to the potential radiation exposure risk to the fetus. Clients under enteric precautions due to diarrhea, receiving a continuous infusion of intravenous morphine sulfate for cancer pain, or requiring contact precautions and frequent wound irrigations do not pose a risk to pregnant nurses and are appropriate assignments for them. Therefore, the nurse should question the assignment involving the client with the solid-sealed cervical radiation implant as it poses a risk to the fetus.

4. Which fetal heart monitor pattern can indicate cord compression?

A. variable decelerations
B. early decelerations
C. bradycardia
D. tachycardia

Correct answer: A

Rationale: Variable decelerations can indicate cord compression as they are caused by umbilical cord compression or prolapse. This pattern shows an abrupt decrease in heart rate with an erratic shape, often resembling a V or W. Early decelerations (choice B) are typically caused by head compression during contractions and are considered benign. Bradycardia (choice C) is a consistent low heart rate below 110 bpm and is not specific to cord compression. Tachycardia (choice D) is an abnormally high heart rate above 160 bpm and is not associated with cord compression.

5. The laws enacted by states to provide immunity from liability to persons who provide emergency care at an accident scene are called:

A. Good Samaritan laws.
B. HIPAA.
C. Patient Self-Determination Act (PSDA).
D. OBRA.

Correct answer: A

Rationale: The correct answer is Good Samaritan laws. These laws protect individuals who provide voluntary emergency care from being held liable for any unintended injury or harm that may occur during the care. Good Samaritan laws encourage individuals to assist in emergencies without fear of legal repercussions. HIPAA, on the other hand, focuses on safeguarding patient information and privacy, ensuring confidentiality. The Patient Self-Determination Act (PSDA) pertains to a patient's rights to make decisions about their medical treatment and advance directives. OBRA, enacted in the late 1980s, aims to improve the quality of care in nursing homes and enhance residents' quality of life, focusing on nursing home reform and standards, which is not directly related to immunity for emergency care providers.
