Submit

37. A critical value for Hct would be: choose all that apply

>60%

Submit

38. The patient's lab report comes back with a low Hct. What could this be due to? Check all appropriate.

Dehydration

Over hydration

Leukemia

A low WBC count

A high Hgb.

Submit

39. The patient's lab report comes back with an elevated BUN of 28 mg/dl. This may not cause a concern because during the assessment your patient told you: Check all that apply.

The patient stated they were on a high protein diet.

The patient has been drinking and extra 8oz of water per day over the recommended number.

The patient states they have voided twice in the last 4 hours.

A high- protein diet can cause an elevated BUN. Drinking water becomes an issue with high BUN when dehydration is an issue. Voiding twice means the kidneys are working.
