A client converts from normal sinus rhythm at 80 bpm to atrial fibrillation with a ventricular response at 166 bpm. Blood pressure is 162/74 mm Hg. Respiratory rate is 20 breaths per minute with normal chest expansion and clear lungs bilaterally. IV heparin and Diltiazem are given. The nurse caring for the client understands that the main goal of treatment is what?

A nurse is caring for a patient who is being treated for Covid-19 pneumonia and ARDS and requires a mechanical ventilator. The physician orders an arterial blood gas, which provides the following results: pH = 7.18, pCO2= 48 mmHg, HCO3= 29 mEq/L, SaO2=92%. Based on these results, which of the following best describes this patient’s condition?

A patient presents to the emergency department (ED) after being struck in the chest with a baseball bat. Which initial assessment finding is of most concern to the ED nurse?

A nurse notes crackles on a client diagnosed with right middle lobe (RML) pneumonia. In which area would the nurse place the stethoscope to assess the adventitious breath sounds associated with this diagnosis?

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.
