A nurse is reinforcing teaching with a client who has COPD and has been taking long-term high doses of prednisone. Which of the following instructions should the nurse include in the teaching?

• Blood pressure. The client's blood pressure dropped from 104/56 mm Hg to 80/46 mm Hg, indicating worsening hypotension. This suggests fluid volume depletion due to ongoing diarrhea and possible sepsis from Clostridium difficile infection. Hypotension is the priority concern as it can lead to shock and organ dysfunction if not addressed immediately. The nurse should anticipate fluid resuscitation with IV fluids to restore circulatory volume.
• Hgb level. The client's hemoglobin is 17 g/dL, which is elevated compared to normal values (12-16 g/dL). This suggests hemoconcentration, likely due to dehydration from severe diarrhea rather than an actual increase in red blood cell count. While this is concerning, the immediate priority is addressing hypotension before evaluating hemoglobin further.
• Temperature. The client has a persistent fever of 38.9°C (102°F), which indicates an active Clostridium difficile infection. While fever management is important, hypotension takes priority because it can lead to hypoperfusion and organ failure. Antipyretic medications and infection control measures can be initiated after stabilizing blood pressure.
• Potassium level. The client's potassium is 3.1 mEq/L, which is below the normal range (3.5-5.0 mEq/L). Diarrhea leads to potassium loss, increasing the risk of cardiac arrhythmias and muscle weakness. After stabilizing the client’s blood pressure, potassium replacement is critical to prevent life-threatening hypokalemia-related complications such as cardiac dysrhythmias.
• Abdominal findings. The client has a soft, distended abdomen with hyperactive bowel sounds and watery stools with mucus, consistent with Clostridium difficile infection. While these findings confirm the diagnosis, the more urgent issues of hypotension and electrolyte imbalances must be addressed first before further gastrointestinal assessment.
• Hct level. The hematocrit is elevated (48%), which aligns with hemoconcentration from dehydration. However, fluid resuscitation will help correct this, making it a secondary concern after addressing blood pressure and potassium levels.

A. A pregnant parent. A child can receive the varicella vaccine even if the parent is pregnant. While the varicella vaccine is a live attenuated vaccine, the vaccinated child does not pose a significant risk of transmission to others. The parent should avoid direct contact with the vaccinee's rash if one develops, but this is not a contraindication to immunization.

B. Receiving treatment for leukemia. Children undergoing treatment for leukemia often have weakened immune systems due to chemotherapy or radiation. The varicella vaccine is a live attenuated vaccine, meaning it contains a weakened form of the virus that could cause severe illness in immunocompromised individuals. These children should not receive live vaccines until their immune function improves and their healthcare provider approves vaccination.

C. Taking acetaminophen for mild discomfort. Acetaminophen is an over-the-counter pain reliever and fever reducer that does not interfere with the efficacy or safety of the varicella vaccine. There is no evidence that mild analgesic use before or after vaccination affects immune response, so it is not a reason to withhold the immunization.

D. An allergy to eggs. Unlike some influenza and yellow fever vaccines, the varicella vaccine is not produced using egg-based components. An egg allergy is not a contraindication to receiving the varicella vaccine, as it does not contain egg proteins.
