BHU NO - 2015
Medical & Surgical Nursing
Medium

All of the following instructions are given to a patient before computed tomography (CT) scan, except?

Appeared in: BHU NO - 2015

Explanation

  • This statement is incorrect because CT scans use ionizing radiation, which is potentially harmful to a developing fetus, especially during the first trimester.
  • A critical nursing responsibility is to screen for pregnancy before any radiological procedure to prevent fetal exposure to radiation.
  • Providing false reassurance that a CT scan is safe during pregnancy is a serious breach of patient safety protocols.

Why Other Options Were Wrong

  • Option A: This is a standard and correct instruction given to patients for comfort during the procedure.
  • Option B: This is a critical and correct instruction to prevent metallic artifacts from degrading the quality of the CT images.
  • Option D: This statement, while potentially true for managing dengue, is completely irrelevant to the context of preparing for a CT scan.

Clinical Relevance
  • Nursing practice connection: Safe nursing care depends on performing Patient safety and instructions for Computed Tomography (CT) scan in the correct sequence, documenting the action clearly, and monitoring for the expected response.
  • A nurse's primary role in pre-procedural care is patient safety. This includes meticulous screening for contraindications like pregnancy or allergies to contrast media.
  • Accurate patient education is vital. A nurse must be able to explain the reasons behind instructions (e.g., why metal is removed) to ensure patient compliance and reduce anxiety.
  • What if? If a patient is pregnant and urgently needs a CT scan for a life-threatening condition (e.g., pulmonary embolism), the protocol changes. The healthcare team (including radiologists and obstetricians) would weigh the risks and benefits, consider alternative diagnostics (like MRI or V/Q scan), and if a CT is necessary, use shielding to protect the fetus as much as possible.
How to Approach the Question
  • First, identify the core subject of the question: pre-procedure instructions for a CT scan.
  • Note the keyword 'except'. This means you are looking for the option that is NOT a correct instruction or is inappropriate.
  • Evaluate each option's relevance and accuracy in the context of a CT scan.
  • Option A (loose clothing) and Option B (remove metal) are standard, correct instructions.
  • Option C makes a claim about pregnancy safety. Recall that CT scans use X-rays, which are a form of ionizing radiation. This radiation is known to be a risk to a developing fetus. Therefore, this statement is false and dangerous.
  • Option D is about dengue fever. This is completely unrelated to a CT scan. While it's not an instruction you'd give, Option C is a more clinically significant and dangerous piece of misinformation directly related to the procedure. In medical questions, the option that represents a direct safety risk or contraindication is often the intended answer.
