A staff education nurse is evaluating a group of nurses during a new employee orientation on the use of proper body mechanics when lifting. Which of the following images indicates the appropriate use of ergonomic principles?
A
B
C
The Correct Answer is A
A. First image: The individual is squatting with the knees bent, back straight, and using a wide base of support while keeping the box close to the body. This posture minimizes strain on the lower back and promotes safe lifting mechanics, which aligns with proper ergonomic principles.
B. Second image: The individual is standing upright while holding the boxes away from the body. This increases the lever arm and places excessive strain on the lumbar spine, increasing the risk of injury.
C. Third image: The individual is bending at the waist while lifting the boxes onto a surface. Bending at the waist with a rounded back significantly increases pressure on the lumbar vertebrae and is considered unsafe body mechanics.

Correct Answer is ["A","B","D"]
Explanation
Rationale for correct choices
• Migraine headaches with aura: Combined oral contraceptives (COCs) increase the risk of ischemic stroke in individuals with migraine with aura. Estrogen-containing contraception can exacerbate cerebrovascular risk, making it a contraindication regardless of age or other vascular risk factors. Even with good glycemic control, the presence of aura elevates stroke risk significantly.
• History of deep vein thrombosis: COCs increase the risk of venous thromboembolism (VTE). A previous DVT is a strong contraindication because estrogen-containing contraceptives can trigger recurrence. Even if the event occurred years ago, the risk remains elevated, particularly in the presence of other risk factors such as immobility or hypercoagulable states.
• Diabetes mellitus (long-standing): Although the client currently has well-controlled blood sugar (HbA1c 6.7%), the duration of diabetes (24 years) significantly increases the risk of cardiovascular disease. Estrogen-containing contraceptives further elevate cardiovascular and thrombotic risk, making long-standing diabetes a relative contraindication.
Rationale for incorrect choices
• Lifetime nonsmoker / Rare alcohol use: Non-smoking status reduces cardiovascular risk, which is protective rather than contraindicating. Alcohol use in small amounts does not increase risk significantly.
Correct Answer is B
Explanation
A. Candidiasis: Candidiasis is a common fungal infection that is not nationally notifiable. While it may require treatment, it does not need to be reported to the state health department for public health surveillance.
B. Chlamydia: Chlamydia is a nationally notifiable sexually transmitted infection. Reporting to the state health department is required to monitor prevalence, track outbreaks, and implement public health interventions to reduce transmission.
C. Herpes simplex virus: Genital herpes infections are not generally reportable to public health authorities in most states, though some jurisdictions may require reporting under specific circumstances. It is not considered nationally notifiable in the same way as chlamydia.
D. Human papillomavirus: HPV infection is highly prevalent and usually asymptomatic, and it is not a nationally notifiable disease. Public health efforts focus on vaccination and screening rather than mandatory reporting.
