- B. Before the procedure, the patient should remove all jewelry, metallic objects, and buttons above the waist
- C. A signed consent is not required
- D. Eating, drinking, and medications are allowed before this test
Correct Answer: A
Rationale: The correct answer is A because there are contraindications for chest X-rays, such as pregnancy or concerns about radiation exposure. Patients may need to remove jewelry and metallic objects to prevent interference with the imaging.

It is essential for patients to follow fasting instructions before certain types of chest X-rays to obtain accurate results.

After 1 week of hospitalization, Mr. Gray develops hypokalemia. Which of the following is the most significant symptom of his disorder?
- A. Lethargy
- B. Increased pulse rate and blood pressure
- C. Muscle weakness

Which of the following procedures always requires surgical asepsis?
- A. Vaginal instillation of conjugated estrogen
- B. Urinary catheterization
- C. Nasogastric tube insertion
- D. Colostomy irrigation
Correct Answer: B
Rationale: Surgical asepsis, which involves maintaining a sterile field and preventing contamination in a surgical setting, is required for urinary catheterization as it involves entering a sterile body cavity.

Correct Answer: A
Rationale: In this scenario, if the nurse makes a false verbal statement about the physician being incompetent, it is considered slander. Slander is the act of making defamatory spoken statements or gestures. Libel, on the other hand, refers to defamatory statements that are written or published.
