The nurse is preparing to assess the client's wound for tunneling.
Where will the nurse place the instrument to determine the depth of tunneling?

Choice A rationale

Excoriated skin is a significant concern due to the enzymes and acidity found in liquid stool, which can lead to rapid skin breakdown in the perianal area. While painful and a risk for secondary infection, it is usually localized and not immediately life-threatening. Proper barrier creams and hygiene can manage this issue. While important for nursing care, it does not carry the same systemic urgency as the loss of vital body fluids.

Choice B rationale

Malnutrition can occur if diarrhea is chronic, as rapid transit time through the intestines prevents the adequate absorption of nutrients, vitamins, and minerals. However, malnutrition is typically a slow-developing complication rather than an acute physiological emergency. In the context of a client currently experiencing diarrhea, the nurse must prioritize immediate stability over long-term nutritional status. Acute fluid loss poses a much more immediate threat to the client's physiological homeostasis.

Choice C rationale

Urinary incontinence is generally not a direct physiological result of diarrhea, although the urgency of diarrhea might cause accidental soiling. While it presents a challenge for hygiene and comfort, it is not a physiological response that threatens the client's vital signs or organ function. The nurse should address incontinence through frequent rounding and skin care, but it remains a lower priority compared to the systemic effects of significant fluid and electrolyte depletion.

Choice D rationale

Dehydration is the most critical concern because diarrhea involves the rapid loss of water and essential electrolytes like potassium and sodium. Severe dehydration leads to decreased circulating blood volume, which can cause hypotension, tachycardia, and potentially hypovolemic shock. Normal fluid balance is essential for cellular function and organ perfusion. Because diarrhea bypasses the large intestine's ability to reabsorb water, the risk of rapid systemic collapse makes dehydration the primary nursing priority.

Choice A rationale

Taking a fire extinguisher to the room follows the acronym PASS, but in the sequence of fire safety represented by the acronym RACE, extinguishing the fire is the very last step. The nurse must first ensure that the alarm is sounded to alert the entire facility and the fire department. Attempting to fight a fire before the alarm is activated could lead to the fire spreading unnoticed by others, which puts the entire building and all occupants at risk.

Choice B rationale

While calling 911 is an important part of emergency response, pulling the fire alarm is a faster and more efficient way to alert all personnel in a hospital setting. The fire alarm system is often directly linked to the fire department and simultaneously activates internal alerts and fire doors. Relying solely on a phone call may delay the immediate localized response needed to contain the situation. The alarm ensures that the specific location of the fire is identified.

Choice C rationale

According to the RACE acronym, which stands for Rescue, Alarm, Confine, and Extinguish, the second action after rescuing the client is to activate the fire alarm. This ensures that the fire department is notified and that all staff members are aware of the emergency. Promptly pulling the alarm allows the facility to begin its established fire protocols, which are essential for the safety of everyone in the building. It is the most critical next step.

Choice D rationale

Evacuating all clients on the nursing unit is a later step in the fire safety protocol, typically occurring if the fire cannot be contained or if ordered by the fire marshal. The immediate priority after removing the person in danger is to sound the alarm. Evacuation is a complex and high-risk process that should be coordinated based on the severity and location of the fire. Moving too many people prematurely can create chaos and block the access of emergency responders.
