Extract:
Question 1 of 5
The nurse is preparing an Injection of 10 units of regular Insulin and 5 units of NPH insulin from two vials. The nurse should:
Correct Answer: B
Rationale: Injecting air into both vials (NPH first then regular) and withdrawing regular insulin first prevents NPH contamination in the regular insulin vial ensuring accurate dosing. Other sequences risk mixing insulins or incorrect dosing affecting glycemic control.
Question 2 of 5
A postoperative client has an abdominal incision and a Penrose drain. Both are covered with an abdominal dressing. Which is an important nursing action associated with caring for a client with a Penrose drain?
Correct Answer: A
Rationale: Changing soiled dressings carefully prevents infection and ensures proper gravity drainage with a Penrose drain which lacks a reservoir or negative pressure system. Pinning the drain risks dislodgement and negative pressure or reservoir filling are not applicable to Penrose drains.
Question 3 of 5
The nurse is caring for a client who has been wearing a nitroglycerin patch and receives an order to start a nitroglycerin intravenous Infusion. The old patch must be removed from the client's body in order to avoid:
Correct Answer: C
Rationale: Removing the nitroglycerin patch prevents overdose as both patch and IV infusion deliver the drug systemically risking excessive vasodilation and hypotension. Skin irritation is a side effect interactions are not primary and patch loss is irrelevant when switching routes.
Question 4 of 5
The client has had a surgical debridement of a wound which is starting to heal. In order to further promote healing this client should be encouraged to consume a balanced diet with emphasis on increased:
Correct Answer: B
Rationale: Vitamin C is essential for collagen synthesis and wound healing as it supports tissue repair and immune function. Carbohydrates provide energy but are not specific to healing calcium aids bone health and vitamin E’s antioxidant role is less critical for wounds.
Question 5 of 5
The nurse knows that which form of medication delivery results in the most predictable onset and most bioavailability to the client?
Correct Answer: A
Rationale: Intravenous delivery provides immediate onset and 100% bioavailability by directly entering the bloodstream bypassing barriers like the gastrointestinal tract or skin. Oral routes face first pass metabolism subcutaneous absorption varies with tissue and transdermal has slow onset due to skin diffusion.
