Extract:
Question 1 of 5
Which one of the following blood levels would provide the nurse with the most information about the ability of the client's blood to transport oxygen? The:
Correct Answer: D
Rationale: Hemoglobin carries oxygen in the blood binding it in red blood cells making its level the best indicator of oxygen transport capacity. Carbon dioxide is exhaled surfactant aids lung compliance and bicarbonate regulates pH none directly affect oxygen transport.
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
When doing the client's skin assessment the nurse notes a 3 cm area of partial thickness skin loss that looks like a blister on the client's sacral area. The nurse consults the wound care nurse who stages the wound as a pressure ulcer.
Correct Answer: B
Rationale: Partial thickness skin loss appearing as a blister indicates a Stage II pressure ulcer involving the epidermis and dermis. Stage I is intact skin with redness Stage III involves full-thickness loss and Stage IV includes deep tissue damage like muscle or bone.
Question 4 of 5
The nurse is to administer a volume of 2 mL intramuscularly (IM) to a 150-pound client. Assuming that there are no skin problems which is the preferred site for the injection?
Correct Answer: C
Rationale: The ventrogluteal site is preferred for IM injections in adults due to its safety (avoids sciatic nerve) and vascularity accommodating 2 mL comfortably. Deltoid is less suitable for larger volumes dorsogluteal risks nerve injury and vastus lateralis is preferred in infants.
Question 5 of 5
The nurse knows that teaching about the use of the spirometer incentive is effective when the client seals the lips around the mouthpiece and:
Correct Answer: A
Rationale: Inhaling slowly to raise the ball and holding it promotes lung expansion and prevents atelectasis which is the correct incentive spirometer technique to improve ventilation and prevent postoperative complications. Exhaling or rapid forceful inspiration does not achieve sustained lung expansion and blowing into the device is incorrect as it is designed for inhalation.
