Physical examination by the primary care physician reveals skin erythema, tenderness, and swelling consistent with cellulitis. The patient is given a prescription for erythromycin. Which of the following effects must the treating physician be keenly aware of?

Rationale: Erythromycin for cellulitis risks cholestatic jaundice , especially in patients with gallstone history. Abdominal discomfort , nausea , and vomiting (E) are common but less severe. Tinnitus is rare. Jaundice, from hepatic dysfunction, requires monitoring given her biliary background.
Question 2 of 5
The nurse is to administer enteral medications to a patient who cannot swallow and is receiving continuous enteral feedings. Which is correct concerning administration of the enteral medications?
Correct Answer: B
Rationale: Liquid medications should be diluted before administration through a feeding tube to prevent clogging and ensure proper absorption. Adding medications to the enteral solution (A) is not recommended, as it can alter the formula's composition and stability.
Question 3 of 5
When monitoring a patient for signs of hypokalemia, the nurse looks for what early sign?
Correct Answer: D
Rationale: One of the early signs of hypokalemia is muscle weakness. Potassium plays a crucial role in maintaining normal muscle function, including the contraction of skeletal and smooth muscles. A deficiency in potassium can lead to muscle weakness, cramping, and fatigue. It is important for the nurse to monitor any signs of muscle weakness in a patient at risk for hypokalemia as it can progress to more severe complications if left untreated. Seizures and cardiac dysrhythmias are more severe manifestations of hypokalemia that can occur if the condition is not promptly addressed. However, muscle weakness is often an early and noticeable sign that can alert healthcare providers to the need for intervention.
