A nurse is caring for a client who is receiving parenteral nutrition and identifies that the client has hyperkalemia. Which of the following actions should the nurse take?

A. 0.45% sodium chloride: 0.45% sodium chloride solution, also known as half-normal saline, is a hypotonic solution used for rehydration and maintenance fluid therapy. However, in cases of
major burns where there is a significant loss of fluid and electrolytes, isotonic solutions are generally preferred.
B. Lactated Ringer's: Lactated Ringer's solution is an isotonic crystalloid solution that closely resembles the electrolyte composition of extracellular fluid. It is commonly used for fluid resuscitation in clients with major burns to replace lost fluids and electrolytes and restore
intravascular volume.

C. Dextrose 5% in water: Dextrose 5% in water is a hypotonic solution used primarily for hydration in clients with normal electrolyte levels or as a vehicle for administering medications.
It is not typically used for fluid resuscitation in clients with major burns, as it does not adequately replace lost electrolytes.
D. Dextrose 5% in 0.45% sodium chloride: This solution combines dextrose 5% and 0.45% sodium chloride and is used for maintenance fluid therapy and mild dehydration. However, in cases of major burns where there is significant fluid and electrolyte loss, isotonic solutions like lactated Ringer's or normal saline are preferred for fluid resuscitation.

A. Respiratory rate: While propranolol can potentially affect respiratory function in individuals with certain respiratory conditions, such as asthma, assessing the respiratory rate is not typically a priority assessment before administering propranolol.
B. HR rate: Propranolol is a beta-blocker that primarily affects heart rate and blood pressure.

Therefore, assessing the heart rate (HR) is crucial prior to administering propranolol, as it can cause bradycardia and heart block.
C. Pain level: Propranolol is not typically associated with pain modulation or analgesic effects.

Assessing pain level may be relevant for other medications or conditions but is not specifically related to propranolol administration.
D. Temperature: Propranolol does not typically affect body temperature, and assessing temperature is not typically necessary before administering propranolol.
