A nurse, after working 2 weeks at the site of the largest natural disaster to hit the United States, returns home. Which of the following behaviors would suggest the nurse needs professional assistance?

Correct Answer: A

Rationale: The fact that the nurse needs to continue to ventilate about the disaster, even after the family has quit listening, would suggest a delayed stress reaction that is not resolving and therefore warrants professional intervention. The nurse presenting at a college about the disaster demonstrates that the nurse is able to engage in conversations about the disaster after it has occurred. It is understandable that the nurse would return exhausted and moody. Indeed, concerns of major importance to family members may seem trivial when compared with problems the disaster victims were confronting.

Correct Answer: B

Rationale: Hepatitis B surface antigen screening is recommended for all pregnant women to prevent vertical transmission. HIV screening is also standard, but (B) is the best single answer here based on universal guidelines. Hemoglobin electrophoresis is for specific risk groups, and ultrasound, while common, isn’t a screening test for all.

Correct Answer: A

Rationale: Calcium channel blockers relieve angina but don’t consistently reduce mortality in coronary heart disease, unlike beta blockers and aspirin. CABG improves survival in severe cases, and nitrates help symptoms, making (A) the exception.

Correct Answer: D

Rationale: Rubella vaccine is recommended for healthcare workers to prevent transmission. BCG, typhoid, and pneumococcal vaccines are not routinely required unless specific risks apply.

Correct Answer: C

Rationale: Diphtheria toxoid provides antitoxin for about 10 years, requiring boosters. It doesn’t prevent carriage or infection, nor does it confer lifelong immunity or frequent reactions.
