A nurse is reviewing the results of laboratory screenings for a 9-month-old infant.
Which of the following results should the nurse report to the provider?

Assign the client to a private room with negative air pressure.

Rationale:

• A. Incorrect. Restricting fresh flowers from the client's room is not necessary for infection control purposes. However, some clients with pulmonary tuberculosis may have hypersensitivity reactions to certain plants or flowers, so the nurse should assess the client's allergies before allowing them in the room.
• B. Incorrect. Maintaining a distance of 1.8 m (6 feet) from the client is not sufficient to prevent transmission of tuberculosis. Visitors should also wear a HEPA respirator and limit their contact time with the client.
• C. Incorrect. A surgical mask is not adequate to protect the nurse from inhaling airborne droplet nuclei that contain Mycobacterium tuberculosis. The nurse should wear a high-efficiency particulate air (HEPA) respirator when providing client care.
• D. Correct. Assigning the client to a private room with negative air pressure is the most effective way to prevent the spread of tuberculosis to other clients and staff members. The room should have at least six air exchanges per hour and an exhaust system that vents directly to the outside.

Jaundice.

Rationale:

• A. Weight loss is not a common or serious adverse effect of valproic acid. Valproic acid can cause weight gain, not weight loss.
• B. Jaundice is a sign of liver damage, which is a serious and potentially fatal adverse effect of valproic acid. Valproic acid can impair fatty acid metabolism and mitochondrial function, leading to hepatotoxicity and steatosis. The nurse should monitor the client's liver function tests and report any signs of jaundice, such as yellowing of the skin or eyes, dark urine, or clay-colored stools .
• C. Bradycardia is not a common or serious adverse effect of valproic acid. Valproic acid can cause cardiac arrhythmias, but they are usually tachycardic, not bradycardic.
• D. Polyuria is not a common or serious adverse effect of valproic acid. Valproic acid can cause hypernatremia and hypocalcemia, which can affect urine output, but polyuria is not a specific symptom of these electrolyte imbalances.
