Question 1 of 5
A public health nurse is preparing an educational handout about rubella, commonly known as measles. All of the following statements should be included in the informational handout EXCEPT
Correct Answer: B
Rationale: Rubella’s incubation period is 12-23 days, not 3-7 days. It spreads via respiratory droplets (coughing/sneezing), not skin-to-skin. Symptoms include fever and rash, but runny nose and cough are more typical of measles.
Question 2 of 5
A client telephones the emergency room stating that she thinks that she is in labor. The nurse should tell the client that labor has probably begun when:
Correct Answer: D
Rationale: Contractions 5 minutes apart indicate the onset of active labor, prompting further evaluation.
Question 3 of 5
The physician has ordered intravenous fluid with potassium for a client admitted with gastroenteritis and dehydration. Before adding potassium to the intravenous fluid, the nurse should:
Correct Answer: A
Rationale: Adequate urinary output (at least 30 mL/hr) must be confirmed before adding potassium to IV fluids to prevent hyperkalemia.
Question 4 of 5

Question 5 of 5
The nurse is caring for a client receiving supplemental oxygen. The effectiveness of the oxygen therapy is best determined by:
