Correct Answer is B

Explanation

A. Flaky, peeling skin (desquamation) occurs in later stages of scarlet fever, typically after the rash begins to fade. It is not an early sign of the disease.
B. A red, sandpaper-like rash that typically begins on the chest and spreads outward is one of the earliest indications of scarlet fever. This rash is caused by exotoxins produced by Streptococcus pyogenes and is a hallmark sign of the illness.
C. A white coating on the tongue, often followed by a characteristic “strawberry tongue,” develops later in the progression of scarlet fever rather than as an early symptom.
D. While fever is a common symptom of streptococcal infections, it is not the earliest indicator of scarlet fever. The rash usually appears within 12 to 48 hours of fever onset, making it a more specific early sign.

A. Obtain postoperative vital signs for a client one day following unilateral knee arthroplasty. B. Start the second blood transfusion for a client twelve hours following a below knee amputation. C. Initiate patient controlled analgesia (PCA pumps for two clients immediately postoperatively. D. Perform daily surgical dressing change for a client who had an abdominal hysterectomy. E. Administer a dose of insulin per sliding scale for a client with type 2 diabetes mellitus (DM).

Correct Answer is ["A","D","E"]

Explanation

A. Obtain postoperative vital signs: This task is within the scope of practice for a practical nurse (PN) as it involves monitoring and recording the vital signs of a client post-surgery, which is a fundamental nursing skill.

B. Start the second blood transfusion: This task is typically reserved for a registered nurse (RN) due to the complexity and potential complications associated with blood transfusions.

C. Initiate PCA pumps: The initiation of PCA pumps is generally a responsibility of the RN because it requires assessment and understanding of the medication dosage and patient pain management needs.

D. Perform daily surgical dressing change: This is an appropriate task for a PN as it involves wound care and monitoring for signs of infection, which are within the PN's capabilities.

E. Administer a dose of insulin per sliding scale: Administering medications, including insulin, is a task that can be delegated to a PN, provided they have the knowledge and skills to do so safely.
