A nurse in a PACU is assessing a client who has a newly created colostomy. Which of the following findings should the nurse report to the provider?

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.

Choice A Reason:

Cool, clammy skin is a common symptom in patients with atrial fibrillation, especially when the heart rate is very high. This symptom occurs due to decreased cardiac output, which leads to poor perfusion of the skin. When the heart is beating too fast, it doesn’t have enough time to fill properly, resulting in less blood being pumped out to the body. This can cause the skin to feel cool and clammy as the body tries to compensate for the reduced blood flow.

Choice B Reason:

Respiratory rate of 20 is within the normal range for adults, which is typically 12-20 breaths per minute. While it is important to monitor respiratory rate in patients with atrial fibrillation, a rate of 20 does not indicate any immediate distress or abnormality. Therefore, this choice is not particularly relevant to the assessment of a patient with a heart rate of 143 beats/min due to atrial fibrillation.

Choice C Reason:

Flushing of the skin is not a typical symptom associated with atrial fibrillation. Flushing can occur due to various reasons such as fever, anxiety, or certain medications, but it is not directly linked to the high heart rate or the irregular rhythm seen in atrial fibrillation. Therefore, this choice is not applicable in this context.

Choice D Reason:

Hypotension (low blood pressure) is a significant concern in patients with atrial fibrillation, especially when the heart rate is very high. The rapid heart rate can lead to decreased cardiac output, as the heart does not have enough time to fill properly between beats. This can result in lower blood pressure, which can cause symptoms such as dizziness, fainting, and fatigue. Monitoring blood pressure is crucial in managing patients with atrial fibrillation to prevent complications.

Choice E Reason:

Chest discomfort is a common symptom in patients with atrial fibrillation, particularly when the heart rate is very high. The irregular and rapid heart rate can cause the heart to work harder, leading to increased oxygen demand and potentially reduced oxygen supply to the heart muscle. This imbalance can result in chest pain or discomfort, which is a warning sign that the heart is under stress. It is important to assess and address chest discomfort promptly to prevent further cardiac complications.
