NCLEX RN Nursing Exam
Question 1 of 5.
The nurse is preparing to administer insulin to a client with type 1 diabetes. The client is to receive 10 units of NPH insulin and 5 units of regular insulin in the same syringe. Which action is correct?
A. Draw up the regular insulin first, then the NPH insulin.
B. Draw up the NPH insulin first, then the regular insulin.
C. Mix the insulins in a separate vial before drawing up.
D. Administer the insulins in two separate injections.

Question 2 of 5.
A client tells the nurse that she takes St. John's wort (hypericum perforatum) three times a day for mild depression. The nurse should tell the client that:
A. St. John's wort seldom relieves depression.
B. She should avoid eating aged cheese.
C. Skin reactions increase with the use of sunscreen.
D. The herbal is safe to use with other antidepressants.
Explanation: St. John's wort increases photosensitivity, so sunscreen use may paradoxically increase skin reactions; clients should be cautioned about sun exposure.
