The healthcare provider prescribes and IV solution of regular insulin (Humulin-R) 100 units in 250 ml of 0.45% saline to infuse at 12 units/hour. The nurse should program the infusion pump to deliver how many ml/hour?

The correct answer is A. Flushed, peeling skin

Choice A reason: Flushed, peeling skin is a classic sign of scarlet fever, which is a condition that can arise from Streptococcal pharyngitis. Scarlet fever is characterized by a red rash that can cover most of the body and may lead to the skin peeling. This symptom is a direct reaction to the toxins produced by the Streptococcal bacteria.

Choice B reason: Red bumps across the chest could be indicative of many conditions and are not specifically characteristic of the reaction to toxins produced by Streptococcal bacteria. While a rash is common in scarlet fever, it typically starts on the face or neck and spreads to the rest of the body, rather than presenting as isolated red bumps.

Choice C reason: A white coating on the tongue, often referred to as “strawberry tongue,” is indeed associated with scarlet fever. However, it is not the clearest indication of a reaction to the toxins. The white coating usually precedes the strawberry-like appearance, where the tongue becomes red and bumpy.

Choice D reason: While a high fever is a symptom of scarlet fever, it is not specific to the reaction to toxins from Streptococcal bacteria, as many infections can cause high fevers. The term “protracted” suggests a prolonged fever, which could be seen in various conditions.

Choice A reason: This is a correct answer because continuing to monitor the client for signs of an infection is important to detect any recurrence or complication of MRSA infection. MRSA is a type of bacteria that is resistant to many antibiotics and can cause serious skin, soft tissue, bone, joint, or bloodstream infections. The nurse should assess the client's vital signs, wound appearance, pain level, and laboratory results.

Choice B reason: This is not a correct answer because calling the healthcare provider for a prescription for linezolid is not necessary unless the client has an active MRSA infection that requires treatment. Linezolid is an antibiotic that can be used to treat MRSA infections, but it has potential side effects and interactions that need to be considered. The nurse should not prescribe or administer antibiotics without a valid order.

Choice C reason: This is a correct answer because collecting multiple sets of blood cultures for MRSA screening is important to identify any asymptomatic bacteremia or sepsis that could result from MRSA infection. MRSA can enter the bloodstream through wounds, catheters, or surgical sites and cause life-threatening complications such as endocarditis, osteomyelitis, or pneumonia. The nurse should obtain blood samples from different sites and times and send them to the laboratory for analysis.

Choice D reason: This is a correct answer because placing the client on contact transmission precautions is important to prevent the spread of MRSA to other clients, staff, or visitors. Contact transmission precautions include wearing gloves and gowns when entering the client's room, using dedicated or disposable equipment, and performing hand hygiene before and after contact with the client or their environment.

Choice E reason: This is not a correct answer because obtaining a sputum specimen for culture and sensitivity is not relevant to the client's history of MRSA wound infection. Sputum culture and sensitivity is a test that can be used to diagnose respiratory infections caused by bacteria, fungi, or viruses. The nurse should only obtain a sputum specimen if the client has signs or symptoms of a respiratory infection, such as cough, fever, chest pain, or dyspnea.
