Tighten the roller clamp to stop the infusion.

A patient has been encouraged to increase fluid intake. Which measure would be most effective for the nurse to implement?

b. Keeping fluids readily available for the patient. Having fluids readily available helps promote intake. Explanation of the fluid transportation mechanisms (a) is inappropriate and does not focus on the immediate problem of increasing fluid intake. Meeting short-term outcomes rather than long-term ones (c) provides further reinforcement, and additional fluids should be taken earlier in the day.

The nurse is caring for a client who has had partial removal of the parathyroid gland. The client reports numbness and tingling of the hands and fingers as well as showing signs of tetany. Which imbalance does the nurse suspect?

hypocalcemia

A nurse is monitoring a patient who is receiving an IV infusion of normal saline. The patient is apprehensive and presents with a pounding headache, rapid pulse rate, chills, and dyspnea. What would be the nurse's priority intervention related to these symptoms?

a. Discontinue the infusion immediately, monitor vital signs, and report findings to primary care provider immediately. The nurse is observing the signs and symptoms of speed shock: the body's reaction to a substance that is injected into the circulatory system too rapidly. The nursing interventions for this condition are: discontinue the infusion immediately, report symptoms of speed shock to primary care provider immediately, and monitor vital signs once signs develop. Answer (b) is interventions for fluid overload, answer (c) is interventions for air embolus, and answer (d) is interventions for phlebitis.
