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
None
None
The Correct Answer is C
A. This is incorrect since the load should be held as close to the nurse's center of gravity (the pelvis) as possible.
B. This is incorrect since the back should remain straight or in its natural "S" curve throughout the lift. The power for the lift should come from the gluteal and femoral muscles, not the back.
C. This is correct since the nurse is squatting and bending at the knees, keeping the back straight. Bending at the knees and hips to engage stronger leg muscles rather than the lower back. The object should also be kept close to the torso, not held at arm’s length, shoulders aligned, no twisting of the trunk, and the eyes forward, head aligned with the spine.
D. This is incorrect since the feet placement should be a wide base of support, one foot slightly ahead of the other. The back alignment includes the spine kept straight, no twisting or bending at the waist. Knees should be bent to lower the body, rather than bending forward.

Correct Answer is ["A","B","C","D","F","H"]
Explanation
Rationales for Correct Findings:
- Client lying in the fetal position; This position often indicates severe abdominal pain and discomfort, signaling peritoneal irritation or acute abdomen. It helps reduce tension on the abdominal muscles, which suggests significant underlying pathology such as peritonitis or perforation.
- Abdominal pain rated 10 radiating to right shoulder: Shoulder pain, especially the right side, can be referred pain from diaphragmatic irritation caused by blood or gastric contents in the peritoneal cavity. This suggests a perforated ulcer or ruptured viscus, making it an alarming symptom requiring immediate attention.
- Abdomen distended and rigid: Abdominal rigidity and distension are classic signs of peritonitis, which may result from gastrointestinal perforation or severe intra-abdominal infection. This indicates an emergency, as the patient may require surgery to address the underlying cause.
- Vomited moderate amount bright red emesis: Bright red emesis indicates active upper gastrointestinal bleeding, which can lead to hypovolemia and shock. This finding requires prompt stabilization and diagnostic evaluation to control bleeding and prevent further deterioration.
- Heart rate 120/min: Tachycardia is an early compensatory response to hypovolemia or pain and can be a sign of shock or sepsis. It indicates the body is under stress, and immediate monitoring and intervention are essential to prevent further cardiovascular compromise.
- Blood pressure 70/49 mm Hg: Hypotension with a low systolic pressure indicates significant circulatory compromise, likely from blood loss or septic shock. This requires urgent fluid resuscitation and advanced cardiac monitoring to prevent organ failure.
Rationale for Incorrect Findings:
- Temperature 36.5° C (97.7° F): The temperature is within normal limits, and the absence of fever does not rule out serious abdominal pathology. Fever may develop later in peritonitis or infection, so normal temperature should not delay intervention but does not require immediate follow-up alone.
- Respiratory rate 20/min: This respiratory rate is within normal to mildly elevated range and may reflect mild distress but is not critical at this time. Oxygen saturation is adequate, and the patient is breathing without significant difficulty, so no urgent intervention based solely on this is needed.
- SpO2 95% room air: Oxygen saturation at 95% on room air is borderline but generally acceptable in adults without respiratory disease. It does not indicate respiratory failure and is not the priority concern in this clinical scenario.
Correct Answer is D
Explanation
A. "The client was intubated without complications.": While relevant to the surgical process, this detail is more critical in the operating or PACU setting and less essential for ongoing post-op care unless complications occurred.
B. "The client is a member of the board of directors.": This is not clinically relevant and violates the client’s confidentiality by sharing unnecessary personal information.
C. "There was a total of 10 sponges used during the procedure.": Sponge count is important intraoperatively, but it is not typically necessary in a hand-off unless a count discrepancy occurred.
D. "The estimated blood loss was 250 milliliters.": This is clinically relevant and necessary for postoperative monitoring. It informs the receiving nurse about potential volume loss and the need to monitor for signs of hypovolemia.
