Water-hammer pulse is characterized by which of the following?
a. A normal rhythm is normal; however, it alternates between increased amplitude and decreased amplitude.
b. A high stroke volume that results in an increased rate of ejection of blood flow from the left ventricle followed by a rapid fall in ejection
c. Rhythm that is irregular (pulse with increased amplitude is followed by a pulse with decreased amplitude).
d. Marked decrease (10 mm Hg or more) in pulse amplitude during inspiration and increased amplitude during expiration.
B
Water-hammer pulse is characterized by a high stroke volume that results in an increased rate of ejection of blood flow from the left ventricle followed by a rapid fall in ejection. A normal rhythm is normal; however, it alternates between increased amplitude and decreased amplitude is characteristic of pulsus alternans. bigeminal pulse is characterized by a rhythm that is irregular (pulse with increased amplitude is followed by a pulse with decreased amplitude). Marked decrease (10 mm Hg or more) in pulse amplitude during inspiration and increased amplitude during expiration is characteristic of pulsus paradoxus.

A client is prescribed to take warfarin. The client has also been instructed to avoid taking foods that contain vitamin K to prevent food and drug interactions
Which of the following sources of food should the nurse inform the client to avoid because they contain vitamin K? A) Fish, meats, and vegetable oils C) Milk and dairy products B) Citrus fruits D) Cereals, soybeans, and spinach
At last measurement, the client's vital signs were as follows: oral temperature 98°F (36.7°C), heart rate 76, respiratory rate 16, and blood pressure (BP) 118/60. Four hours later, the vital signs are as follows:
oral temperature 103.2°F (38.5°C), heart rate 76 beats/minute, respiratory rate 14 breaths/minute, and blood pressure 120/66. Which should the nurse's first intervention be at this time? 1) Ask the client if he has had a warm drink in the last 30 minutes. 2) Notify the primary care provider of the client's temperature. 3) Ask the client if he is feeling chilled. 4) Take the temperature by a different route.
The results of an amniocentesis conducted just prior to birth showed a fetus's lecithin/sphingomyelin ratio as being 1:1 . From this information, for which respiratory problem should the nurse anticipate providing care once the baby is delivered?
