Exam Questions and Answers 22.An older adult client visits the community health clinic, reporting the onset of pain, redness, and swelling in the right eye. What is the most important for the clinic nurse to ask the client?Rationale--- correct precise answer --- The combination of pain, redness, and swelling in the eye could be indicative of a drug reaction or side effect, especially in older adults who may be on multiple medications. Some med-ications, such as antibiotics (e.g., sulfonamides) or diuretics, can cause ocular reactions or increase the risk of infection or inflammation in the eye. Asking about new medications helps identify whether a drug could be contributing to the symptoms.--- correct precise answer --- Have you started any new medications recently? 23.After assessing the health needs of an elementary school, the nurse iden-tifies that an increased incidence of bicycle injuries is a significant issue. The nurse develops a 2-month program with the goal of eliminating bicycle in-juries in the school. The program includes educational pamphlets sent home to parents and two educational sessions conducted by the school nurse. What action should the nurse take to evaluate the effectiveness of the program?Ra-tionale--- correct precise answer --- The most effective way to evaluate the success of an injury prevention program is by measuring changes in the incidence of the targeted issue — in this case, bicycle injuries — before and after the program. By comparing the number of injuries at the start of the program to those at the end, the nurse can directly assess whether the program had an impact on reducing bicycle injuries.--- correct precise answer --- Compare the incidence of bicycle injuries at the beginning and end of the program. 24.A home health nurse is examining the lab results of several patients with a history of heart failure (HF). Which patient's finding should the nurse imme-diately report to the healthcare provider?Rationale--- correct precise answer --- B-type natriuretic peptide (BNP) is a marker of heart failure (HF). Elevated BNP levels suggest that the heart is under increased stress or experiencing fluid overload, a common issue in HF. A BNP level of 550 pg/mL is elevated, and although it is not an extreme value, it still indicates the potential for worsening heart failure and warrants further evaluation by the healthcare provider. Typ-ically, BNP levels above 400 pg/mL suggest a high likelihood of heart failure, and levels in the 500-1000 pg/mL range may indicate decompensated heart failure.--- correct precise answer --- B-type natriuretic peptide (BNP) level of 550 pg/mL (550 ng/L).
