A Roman Catholic client is preparing to have magnetic resonance imaging. He wants to wear his metal crucifix pendant while he is receiving the test. Which of the following is an appropriate response by the nurse?

  • A. "Because it gives you comfort, you may wear it."?
  • B. "It is a violation of religious rights to forbid it."?
  • C. "I am sorry, but it is not safe for you to wear the crucifix during this test."?
  • D. "You may wear it because it is important to you."?
Correct Answer: C

Rationale: No metal objects may be worn while receiving magnetic resonance imaging due to safety risks involved with the strong magnet. The correct response by the nurse should prioritize the safety of the client. Allowing the client to wear the metal crucifix poses a risk of injury or interference with the imaging process. Option A is not appropriate as safety takes precedence over comfort in this situation. Option B is incorrect as it does not address the safety concerns associated with wearing metal objects during an MRI. Option D is also incorrect as it fails to acknowledge the safety issue involved and instead focuses solely on the importance to the client. It is important for the nurse to offer alternative forms of spiritual support that do not pose a risk during the MRI procedure.

The nurse is teaching a client about communicable diseases and explains that a portal of entry is:

  • A. a vector.
  • B. a source, like contaminated water.
  • C. food.
  • D. the respiratory system.
Correct Answer: D

Rationale: The correct answer is 'the respiratory system.' A portal of entry is the path through which a microorganism enters the body. In the case of communicable diseases, the respiratory system can serve as a portal of entry for pathogens such as viruses or bacteria. Choices A, B, and C are incorrect. A 'vector' is an organism that transmits disease, not the entry point for pathogens. Contaminated water or food can act as sources or reservoirs of disease-causing microorganisms, not portals of entry.

Which of the following syndromes associated with incomplete lesions of the spinal cord results from damage to one-half of the spinal cord?

  • A. Brown-Séquard syndrome
  • B. posterior cord syndrome
  • C. central cord syndrome
  • D. cauda equina syndrome
Correct Answer: A

Rationale: Brown-Séquard syndrome is indeed associated with incomplete lesions of the spinal cord, and it specifically results from damage to one-half of the spinal cord. This syndrome manifests as ipsilateral motor paralysis, ipsilateral loss of vibration and proprioception, and contralateral loss of pain and temperature sensation. Posterior cord syndrome mainly involves the loss of proprioception and vibratory sense, while sparing motor function and pain sensation. Central cord syndrome typically presents with more weakness in the upper extremities compared to the lower extremities due to central spinal cord damage. Cauda equina syndrome affects the nerve roots at the level of the conus medullaris, leading to symptoms like lower extremity weakness, numbness, and bowel/bladder dysfunction.

Which of the following indicates a hazard for a client on oxygen therapy?

  • A. A 'No Smoking' sign is on the door.
  • B. The client is wearing a synthetic gown.
  • C. Electrical equipment is grounded.
  • D. Matches are removed.
Correct Answer: B

Rationale: The correct answer is that the client is wearing a synthetic gown. A synthetic gown might generate sparks of static electricity, which can be a fire hazard, especially in the presence of oxygen. Clients on oxygen therapy should wear cotton gowns to minimize the risk of fire. The other options are not hazards for a client on oxygen therapy: having a 'No Smoking' sign on the door promotes safety by preventing smoking, ensuring electrical equipment is grounded reduces the risk of electrical hazards, and removing matches decreases the risk of fire hazards.

For which of the following conditions might blood be drawn to assess uric acid levels?

  • A. asthma
  • B. gout
  • C. diverticulitis
  • D. meningitis
Correct Answer: B

Rationale: Uric acid levels are commonly assessed in patients with gout. Gout is a type of arthritis caused by the buildup of uric acid crystals in the joints, leading to inflammation and pain. Monitoring uric acid levels helps in diagnosing and managing gout. Asthma, diverticulitis, and meningitis are not conditions where blood tests for uric acid levels are typically necessary. Asthma is a respiratory condition, diverticulitis involves inflammation of the digestive tract, and meningitis is an infection of the meninges in the brain and spinal cord.

What condition is mammography used to detect?

  • A. pain
  • B. tumor
  • C. edema
  • D. epilepsy
Correct Answer: B

Rationale: Mammography is specifically used to detect tumors or abnormal growths, especially in breast tissue. It is not a tool for identifying pain, edema, or epilepsy. Therefore, the correct answer is 'tumor.' Pain is a symptom, edema is swelling, and epilepsy is a neurological disorder; none of these are conditions typically detected through mammography.
