A nurse in an intermediate intensive care unit is admitting a patient who becomes lethargic and unable to complete sentences. The patient has a heart rate of 34 beats per minute and a blood pressure of 83/48 mm Hg. The nurse applies electrodes to the patient’s chest and limbs and the electrocardiogram (EKG) monitor shows the following rhythm. Which of the following actions should the nurse take?  

Six toy blocks are glued together to form a beam that supports a shear force of 202 N. Each block has dimensions a = 15 mm and b = 45 mm. Determine the horizontal shear stress in the glue between blocks (2) and (3).

A patient is brought to the ED by ambulance after a motor vehicle accident in which the client received blunt trauma to the chest. The patient is in acute respiratory failure, is intubated, and is transferred to the ICU. What assessment parameters should the nurse most closely monitor? Select all that apply, 3 correct answers.

Lorenz curve can be drawn either below or above the 45-degree line.

Loads P = 723 N and Q = 484 N act on an oak beam. Determine the magnitude of the largest shear force (consider both positive and negative values) in the beam. Let a = 0.6 m and b = 1.3 m.

A 172-lb person stands on an oak beam. Determine the vertical reaction force at the right end of the beam. Let a = 84 in. and b = 24 in.

Three 25-lb boxes are placed on an oak beam. Determine the vertical reaction force at the right end of the beam. Let a = 85 in. and b = 23 in.
