Following a recent tattoo, someone should be screened for:
- A. tuberculosis.
- B. herpes.
- C. hepatitis.
- D. syphilis.
Correct Answer: C
Rationale: Following a recent tattoo, someone should be screened for hepatitis. Tattooing puts a client at risk for blood-borne hepatitis B or C if strict sterile procedures are not followed. Tuberculosis is an airborne pathogen, while herpes and syphilis are spread through direct contact like sexual activity. Therefore, hepatitis is the most relevant infection to screen for after getting a tattoo.

In an obstetrical emergency, which of the following actions should the nurse perform first after the baby delivers?
- A. Place extra padding under the mother to absorb blood from the delivery.
- B. Cut the umbilical cord using sterile scissors.
- C. Suction the baby's mouth and nose.
- D. Wrap the baby in a clean blanket to preserve warmth.
Correct Answer: C
Rationale: In an obstetrical emergency, the immediate action the nurse should take after the baby delivers is to suction the baby's mouth and nose to ensure the infant can breathe properly. This helps clear any potential obstructions and establish a clear airway. Cutting the umbilical cord (Choice B) and wrapping the baby in a clean blanket (Choice D) are important steps but should come after ensuring the baby's airway is clear. Placing extra padding under the mother (Choice A) is not a priority in this emergency situation as the focus should be on the baby's immediate needs for breathing and airway clearance.
Which of the following statements by a client indicates adequate preparation for magnetic resonance imaging?
- A. "I should wear earplugs during the test."?
- B. "I should remove my metal jewelry before the test."?
- C. "I should inform the healthcare provider about my pacemaker."?
- D. "I should inform the healthcare provider about my artificial hip."?
Correct Answer: A
Rationale: The correct statement is, '"I should wear earplugs during the test,"?' as MRI scanners produce loud noises requiring ear protection. Metal objects, including jewelry, are not allowed inside the MRI room due to safety concerns related to the magnetic field. Choices B, C, and D are incorrect. Choice B is wrong because metal objects, including jewelry, are not permitted in the MRI room. Choices C and D are incorrect as having a pacemaker or an artificial hip raises concerns due to the magnetic field in MRI, requiring special precautions or considerations. It is crucial for individuals with such implants to inform their healthcare provider to assess the risks and determine the appropriate course of action.
Which of the following represents a normal serum potassium level?
- A. 1.5 mEq/L
- B. 3.0 mEq/L
- C. 4.0 mEq/L
- D. 6.0 mEq/L
Correct Answer: C
Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).
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.
Quality is defined as a combination of all of the following except:
- A. conforming to standards.
- B. performing at the minimally acceptable level.
- C. meeting or exceeding customer requirements.
- D. exceeding customer expectations.
Correct Answer: B
Rationale: Quality in any context is about meeting or exceeding customer requirements and exceeding customer expectations. It also involves conforming to standards to ensure consistency and reliability. Merely performing at the minimally acceptable level does not encompass the essence of quality, as it sets the bar at the lowest level of acceptability rather than aiming for excellence or customer satisfaction. Therefore, the correct answer is 'performing at the minimally acceptable level,' as this choice falls short in capturing the comprehensive definition of quality.
