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
Explanation
A. "Hold your breath for 10 seconds after each puff.": This allows the medication to deposit deeply into the airways, enhancing absorption and therapeutic effect. It is a key step in proper MDI technique.
B. "Inhale rapidly for 1 to 2 seconds after depressing the canister.": Inhalation should be slow and deep over 3 to 5 seconds to allow proper delivery of the medication into the lungs.
C. “Hold the mouthpiece 4 inches away from your open mouth.”: The preferred technique is to place the mouthpiece directly in the mouth with lips sealed around it unless a spacer is used.
D. "Tilt your head forward while inhaling.": The correct method is to tilt the head slightly back to open the airway and facilitate deeper inhalation of the medication.
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.
