The nurse admits a patient with a low BP who reports severe diarrhea for several days from a Clostridium difficile infection. Which IV fluid would the nurse associate with the need to rapidly replace the patient's fluid volume?
0.45% sodium chloride
0.9% sodium chloride
5% dextrose in 0.9% sodium chloride
5% dextrose in 0.45% sodium chloride
The Correct Answer is B
Choice A reason: 0.45% sodium chloride is a hypotonic solution, which is not ideal for rapidly replacing fluid volume in patients with low blood pressure due to severe diarrhea. Hypotonic solutions can cause fluid to move into cells rather than staying in the vascular space, potentially worsening hypotension.
Choice B reason: 0.9% sodium chloride, also known as normal saline, is an isotonic solution. It is the best choice for rapidly replacing fluid volume in patients with low blood pressure. Isotonic solutions stay in the vascular space and help restore circulating blood volume and blood pressure without causing fluid shifts that can lead to cellular edema or dehydration.
Choice C reason: 5% dextrose in 0.9% sodium chloride is a hypertonic solution, which might not be the most appropriate for initial rapid fluid resuscitation. Hypertonic solutions can draw fluid into the vascular space from the interstitial and intracellular spaces, potentially leading to rapid changes in fluid balance and electrolyte shifts.
Choice D reason: 5% dextrose in 0.45% sodium chloride is also a hypertonic solution but with a hypotonic component (0.45% sodium chloride). This combination is not typically used for rapid fluid resuscitation because it can cause fluid shifts that are less predictable and may complicate the patient's electrolyte balance and hydration status.

Correct Answer is ["A","C"]
Explanation
Choice A reason: Performing assisted coughing is crucial for patients with spinal cord injuries who may have weakened respiratory muscles. Assisted coughing helps clear secretions from the airways, thus improving oxygenation and preventing respiratory complications like pneumonia.
Choice B reason: Administering steroids is not a primary intervention for addressing hypoxia in patients with spinal cord injuries. Steroids can be used to reduce inflammation, but they do not directly improve respiratory status or oxygenation.
Choice C reason: Administering oxygen is a direct and effective intervention for managing hypoxia. Supplemental oxygen helps ensure that the patient maintains adequate blood oxygen levels, which is critical for overall tissue perfusion and function.
Choice D reason: Administering antibiotics is not immediately relevant to the treatment of hypoxia unless there is an underlying infection causing or contributing to respiratory distress. Antibiotics are used to treat infections, not directly to improve respiratory status in cases of hypoxia.
Correct Answer is ["A","B"]
Explanation
Choice A reason: Keeping the radiation area clean with mild soap and water helps maintain hygiene and prevent infection. It is important to use gentle, non-irritating cleansers to avoid aggravating the skin that is already sensitive due to radiation.
Choice B reason: Avoiding exposure of the radiation site to extreme temperatures is crucial. Heat can increase irritation, and cold can cause additional discomfort. Protecting the area from extreme temperatures helps in reducing skin reactions and promoting healing.
Choice C reason: Wearing tight clothing is not recommended for patients undergoing radiation therapy. Tight clothing can cause friction and irritation on the already sensitive radiation site, potentially worsening skin reactions.
Choice D reason: Applying fragrant lotions to the radiation area is not advised. Fragrances and certain chemicals in lotions can irritate the skin and lead to adverse reactions. It is better to use unscented, gentle moisturizers if needed.
