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.
D.
A
B
C
D
The Correct Answer is A
Using proper body mechanics is vital to prevent injury and ensure safe lifting. Key principles include keeping the back straight and neutral to reduce spinal stress and bending at the knees and hips to engage stronger leg muscles rather than the lower back. Maintaining a shoulder-width stance provides stability, while holding objects close to the body decreases spinal strain. Lifting with the legs, not the back, further protects the spine. Twisting should be avoided—pivoting with the feet maintains alignment and reduces injury risk. Keeping the head and neck aligned with the spine improves posture and visual focus. Using smooth, controlled movements prevents muscle strain and dropped objects. Assessing an object’s weight before lifting helps determine if help or equipment is needed, preventing overexertion. Supportive footwear with a good grip ensures balance and minimizes fall risk. These ergonomic practices promote safety, reduce injuries, and are essential in both clinical and everyday environments.

Correct Answer is ["A","C","D","F","H"]
Explanation
A. Blood pressure: An elevated blood pressure of 148/94 mm Hg in a 30-week gestation client indicates potential preeclampsia. This requires follow-up, especially since it is accompanied by other preeclampsia symptoms such as headache and edema. Prompt assessment is essential to prevent progression to severe disease.
B. Respiratory assessment: The client’s respiratory rate is 20/min, even and non-labored, with clear breath sounds and 95% oxygen saturation. These are all within normal limits and do not indicate respiratory distress or compromise, so no immediate follow-up is necessary for this system.
C. Lower extremity assessment: 1+ dependent edema, though mild, can be an early sign of preeclampsia, especially when associated with elevated blood pressure and weight gain. This symptom requires monitoring for progression and possible systemic involvement.
D. Weight assessment: The client gained 0.68 kg (1.5 lb) in a week, which is above the normal range during the third trimester and may represent fluid retention. Coupled with hypertension and edema, it supports the suspicion of preeclampsia and warrants follow-up.
E. Fetal heart tracing: A fetal heart rate of 140/min is within the normal range of 110–160 bpm and shows no signs of distress. No immediate intervention is needed for fetal status at this time based on the tracing.
F. Nausea: Although nausea can be common in pregnancy, when it appears with headache and right upper quadrant pain, it may be part of the symptom complex for preeclampsia or HELLP syndrome. This combination should be followed up with further evaluation.
G. Fundal height: A fundal height of 29 cm at 30 weeks is within acceptable variation (±2 cm of gestational age), indicating appropriate fetal growth. This finding does not require follow-up at this time.
H. DTR: 3+ deep tendon reflexes suggest hyperreflexia, which is a neurological sign that can precede seizures in preeclampsia. When seen alongside elevated blood pressure and other systemic symptoms, it requires urgent follow-up to prevent maternal complications.
Correct Answer is A
Explanation
A. The client is tolerating clear liquids: Following gastric banding surgery, clients typically begin with clear liquids and gradually progress to more solid foods. Tolerating clear liquids 36 hours post-op is expected and indicates appropriate recovery.
B. The client is voiding at least 250 mL/hr: A urine output of 250 mL/hr is abnormally high and could suggest overhydration or other issues. Normal expected output is around 30–50 mL/hr postoperatively.
C. The client is maintaining bed rest: Prolonged bed rest increases the risk of complications like deep vein thrombosis. Clients are generally encouraged to ambulate early unless contraindicated.
D. The client is consuming 1000 calories daily: At 36 hours post-op, the client is not expected to consume high-calorie meals. Intake is usually limited to small amounts of clear liquids to prevent nausea and stress on the surgical site.
