Which lab values would you expect to see when a patient with type 1 diabetes presents in ketoacidosis?
Increased serum bicarbonate
Decreased serum potassium
Urine pH 4.0 (expected range 4.5 to 8)
Serum pH of 7.5 (expected range 7.35 to 7.45)
The Correct Answer is C
A. In diabetic ketoacidosis (DKA), serum bicarbonate is typically decreased, not increased. The decrease is due to metabolic acidosis resulting from the accumulation of ketones.
B. Serum potassium is often elevated in DKA initially due to the shift of potassium from inside the cells to the bloodstream as a result of acidosis. However, potassium levels may drop with treatment, especially with insulin administration, which drives potassium back into cells.
C. Urine pH in DKA is often acidic due to the presence of ketones, which are acidic byproducts of fat metabolism. A urine pH of 4.0 indicates aciduria, which is consistent with ketoacidosis.
D. Serum pH in DKA is typically low (below 7.35), indicating acidosis. A serum pH of 7.5 would suggest alkalosis, which is not typical of DKA.

Correct Answer is C
Explanation
A. Laxatives are used to relieve constipation by promoting bowel movements, not for treating diarrhea.
B. Antimotility agents work by slowing down the movement of the intestines, which can reduce diarrhea, but they do not specifically absorb excess fluid in the fecal matter.
C. Adsorbents, such as activated charcoal or kaolin-pectin, work by absorbing excess fluid in the fecal matter in the colon, which helps to reduce diarrhea without affecting transport processes across the intestinal membranes.
D. Bulk-forming agents, like psyllium, absorb water and increase the bulk of stool, which is used for constipation rather than diarrhea.
Correct Answer is B
Explanation
A. While sterile drapes are important for maintaining a sterile field during the procedure, they do not directly address the issue of privacy.
B. Pulling the curtains around the client's bed is the most appropriate action to ensure privacy during the procedure. It creates a physical barrier to maintain confidentiality and dignity for the client while they undergo the lumbar puncture.
C. Closing the door to the client's room can also help maintain privacy but may not be as effective in a shared space like a hospital ward. Curtains are a more immediate and effective means of providing privacy.
D. Asking family members to leave the room may be necessary for the procedure but does not directly relate to privacy during the procedure. The focus should be on ensuring the environment is private by pulling curtains and closing doors.
