A client with psoriasis returns to the clinic reporting the persistence of several silvery, scaly areas on the elbows and palms that frequently burn and sometimes bleed.
Which prescription should the nurse teach the client to use for the skin condition?

Choice A rationale:

Total protein is a measure of the overall protein content in the blood. It includes albumin and globulin.

While it can be helpful in assessing nutritional status and liver function, it is not directly relevant to the client's current symptoms of pallor and fatigue.

Decreased total protein can indicate malnutrition or liver disease, but these conditions would not typically cause the specific symptoms of pallor and fatigue.

Therefore, total protein is not the most important laboratory value to review in this case.

Choice B rationale:

Hemoglobin is the protein in red blood cells that carries oxygen throughout the body.

Paleness (pallor) is a common sign of anemia, which is a condition characterized by a low hemoglobin level. Fatigue is also a common symptom of anemia, as the body's tissues are not receiving enough oxygen.

Diclofenac, a non-steroidal anti-inflammatory drug (NSAID), can cause gastrointestinal bleeding, which can lead to anemia. Therefore, it is essential for the nurse to review the client's hemoglobin level to assess for potential anemia.

Choice C rationale:

Glucose is a type of sugar that the body uses for energy.

Abnormal glucose levels can cause various symptoms, including fatigue. However, glucose levels would not typically cause pallor.

Additionally, there is no indication in the question stem that the client has any risk factors for diabetes or other disorders that affect glucose metabolism.

Therefore, glucose is not the most likely cause of the client's symptoms.

Choice D rationale:

Sodium is an electrolyte that helps regulate fluid balance in the body.

Abnormal sodium levels can cause various symptoms, including fatigue and weakness. However, sodium levels would not typically cause pallor.

Additionally, there is no indication in the question stem that the client has any risk factors for electrolyte imbalances. Therefore, sodium is not the most likely cause of the client's symptoms.

Choice A rationale:

Lactulose directly addresses the primary cause of hepatic encephalopathy, which is the accumulation of ammonia in the blood. Ammonia is a neurotoxin that can impair brain function, leading to confusion, lethargy, and even coma. Lactulose works by trapping ammonia in the colon, where it can be safely excreted in the stool. This decrease in ammonia levels in the blood allows for the improvement of mental status.

Studies have consistently shown that lactulose therapy can significantly improve mental function in patients with hepatic encephalopathy. This improvement is often seen within a few days of starting treatment.

The nurse should assess the client's mental status regularly to monitor for improvement. This assessment should include evaluating the client's level of consciousness, orientation, attention, memory, and speech.

Improved mental status is a critical therapeutic goal in the treatment of hepatic encephalopathy. It allows patients to regain their independence and participate more fully in their care.

Choice B rationale:

While lactulose can cause diarrhea, which may lead to a slight increase in urine output, this is not the primary therapeutic response that the nurse should expect.

The increase in urine output is typically secondary to the diarrhea and does not directly reflect a reduction in ammonia levels or improvement in mental status.

Choice C rationale:

Lactulose does cause diarrhea, which is a common side effect of the medication.

However, the goal of lactulose therapy is not to reduce the number of liquid stools but rather to trap ammonia in the colon and promote its excretion.

The nurse should monitor the client's stool frequency and consistency to ensure that they are not experiencing excessive diarrhea, which could lead to dehydration and electrolyte imbalances.

Choice D rationale:

While improved mental status may eventually lead to improved mobility, it is not the most immediate or direct therapeutic response that the nurse should expect from lactulose therapy.

The ability to ambulate independently is more likely to be a long-term goal of treatment, rather than an immediate response to lactulose.
