A client is prescribed to receive 375 mL of PRBCs to infuse over 3.5 hours on an infusion pump.
What would the nurse set the infusion pump (mL/hr) to run? (Do not use a leading zero, Round to a whole number)
The Correct Answer is ["107"]
Step 1: The total volume to infuse is 375 mL.
Step 2: The total infusion time is 3.5 hours.
Step 3: To find the infusion pump setting in mL/hr, divide the total volume by the total time: 375 mL ÷ 3.5 hours = 107.14 mL/hr.
Step 4: Round to a whole number: 107 mL/hr. The final calculated answer is 107 mL/hr.

Correct Answer is B
Explanation
Choice A rationale
Fluid-filled vesicles on the chest are not characteristic of Koplik spots. Vesicular rashes are more commonly associated with conditions like varicella (chickenpox) or herpes zoster, where the viral replication leads to the formation of small, elevated, fluid-filled lesions on the skin surface.
Choice B rationale
Koplik spots are pathognomonic for measles, appearing as small, irregular, bright red spots with bluish-white centers on the buccal mucosa, typically opposite the molars. They represent necrotic epithelial cells in the buccal mucosa and are an early diagnostic sign, often appearing 2-3 days before the generalized rash.
Choice C rationale
Enlarged parotid glands are characteristic of mumps, a viral infection affecting the salivary glands, particularly the parotid glands. This condition leads to swelling and tenderness in the areas anterior to the ears and below the jawline, distinct from the oral lesions seen in measles.
Choice D rationale
A gray pseudomembrane covering the pharynx is a hallmark sign of diphtheria, a bacterial infection caused by *Corynebacterium diphtheriae*. This pseudomembrane is a tough, adherent lesion composed of fibrin, bacteria, and necrotic cells that can obstruct the airway, unrelated to measles.
