patient in ED with complaints of severe headache. She states that she has
been out of her BP pills for 3 weeks and cannot afford to buy more. BP
ranges from 250/128 to 200/110. Nitroprusside (Nipride) is being titrated,
and the patient is on O2 by NC. In considering the risk for cardiac failure and
pulmonary edema, consideration should be made to the physiologic principle

phase of the cardiac cycle?
A. Ventricular ejection
B. Isovolumetric contraction
C. Ventricular filling
D. Isovolumetric relaxation - CORRECT-ANSWERSB. Isovolumetric
contraction
A postoperative cardiac surgery patient's blood pressure suddenly drops to
70 mm Hg palpable, with a loss of the a wave in the PAOP waveform. What
change in his cardiac rhythm would cause this change in his PAOP
waveform?
A. Sinus tachycardia
B. Sinus dysrhythmia
C. Atrial tachycardia
D. Atrial fibrillation - CORRECT-ANSWERSD. afib
A 40-year-old patient has been admitted to the critical care unit after
sustaining multiple injuries from a cave-in accident this morning. X-ray
confirm multiple fractures, including the left femur. During the afternoon he
was taken to surgery for internal fixation of the left femur. It is now 10 pm,
and the patient is complaining of severe throbbing pain in his thigh. The
patient received 5 mg of morphine sulfate IV 30 minutes ago. The anterior
left thigh is firm to touch, and the pain increases when the patient flexes his
left leg. The nurse should suspect which of the following?
A. Normal pain related to fractured femur
B. Abnormal pain related to compartment syndrome
C. Abnormal pain related to infection
