A client needs 5 liters of oxygen. Which of the following devices is appropriate for use with an oxygen flow rate of 5 liters? Select all that apply:

Choice A reason: The first priority in this situation is to ensure the client’s airway is secure. Difficulty breathing and stridor indicate a potential airway obstruction, which can be life-threatening. Activating the hospital’s emergency or rapid response system ensures that the client receives immediate medical attention from a team equipped to handle such emergencies. This step is crucial to prevent respiratory arrest and other complications.

Choice B reason: While placing a heart monitor on the client and observing for dysrhythmias is important, it is not the immediate priority in this scenario. The client’s airway and breathing take precedence over monitoring heart rhythms. Once the airway is secured and breathing is stabilized, then monitoring for dysrhythmias can be considered.

Choice C reason: Asking the charge nurse to come see the client immediately is a reasonable action, but it is not the most effective first step. The charge nurse may not have the necessary equipment or expertise to handle an acute airway obstruction. Activating the emergency or rapid response system ensures that a specialized team responds quickly.

Choice D reason: Checking the client’s blood pressure and heart rate is important for overall assessment, but it is not the immediate priority when there is a potential airway obstruction. Ensuring the client can breathe is the most critical action. Vital signs can be checked once the airway is secured.

Choice E reason: Providing a calm and assuring environment for the client is beneficial for reducing anxiety, but it does not address the immediate threat to the client’s airway. While maintaining a calm environment is important, the nurse must first ensure the client’s airway is open and breathing is adequate.

Choice F reason: Placing the emergency cart at the bedside is a preparatory step that can be useful, but it is not the first action to take. The nurse should first activate the emergency or rapid response system to get immediate help. The emergency cart can be brought to the bedside by the responding team.

Choice A Reason:

0.45% sodium chloride (half-normal saline) is an appropriate solution for treating hypernatremia, especially in a client who is NPO (nothing by mouth). This hypotonic solution helps to gradually reduce the serum sodium levels by providing free water to the extracellular space, which dilutes the high sodium concentration. It is essential to administer this solution slowly to avoid rapid shifts in fluid balance, which can lead to cerebral edema.

Choice B Reason:

Dextrose 5% in 0.9% sodium chloride (D5NS) is not the best choice for treating hypernatremia. While it provides some free water, the presence of 0.9% sodium chloride makes it an isotonic solution, which does not effectively lower serum sodium levels. This solution is more suitable for maintaining fluid balance rather than correcting hypernatremia.

Choice C Reason:

Lactated Ringer’s is also not appropriate for treating hypernatremia. This isotonic solution contains electrolytes, including sodium, which can exacerbate hypernatremia rather than correct it. Lactated Ringer’s is typically used for fluid resuscitation and electrolyte replacement in other clinical scenarios.

Choice D Reason:

Dextrose 10% in water (D10W) is a hypertonic solution and is not suitable for treating hypernatremia. While it provides free water, the high concentration of dextrose can lead to rapid shifts in fluid balance and potential complications such as hyperglycemia. This solution is generally used for providing calories and preventing hypoglycemia in specific clinical situations.
