A nurse is caring for a client who has a prescription for amoxicillin. Which of the following findings indicates the client is experiencing an allergic reaction?
Laryngeal edema
Nausea
Cardiac dysrhythmia
insomnia
The Correct Answer is A
A. Laryngeal edema (Correct Answer): Laryngeal edema is a severe allergic reaction that can compromise the airway and lead to respiratory distress. It is a medical emergency and requires immediate intervention. Other signs of a severe allergic reaction may include difficulty breathing, wheezing, and swelling of the face or lips.
B. Nausea: Nausea is a common side effect of many medications, including antibiotics. However, it is not a specific sign of an allergic reaction. Allergic reactions are more likely to involve symptoms such as rash, itching, and swelling.
C. Cardiac dysrhythmia: Cardiac dysrhythmia is not a typical manifestation of an allergic reaction to amoxicillin. Allergic reactions generally involve the immune system and may present with symptoms such as skin rash, itching, or respiratory distress.
D. Insomnia: Insomnia is not a known side effect or manifestation of an allergic reaction to amoxicillin. Allergic reactions are more likely to involve immediate hypersensitivity responses, such as skin reactions or respiratory symptoms.

Correct Answer is D
Explanation
A. Urine specific gravity 1.020: While this value indicates concentrated urine and can be useful in assessing dehydration, it doesn’t specifically confirm effective treatment. High urine specific gravity suggests dehydration because the kidneys are conserving water, but it doesn’t directly confirm the effectiveness of treatment.
B. BUN 28 mg/dl (Blood Urea Nitrogen): Elevated BUN levels can be seen in dehydration, but it's not a direct marker of effective treatment. It indicates dehydration due to increased urea concentration in the blood but doesn’t confirm if the treatment has been effective or not.
C. Serum hematocrit 55%: In dehydration, the blood becomes more concentrated due to water loss, causing an increase in hematocrit levels. However, while this value might indicate dehydration initially, it may not specifically confirm the effectiveness of treatment once initiated.
D. Serum osmolarity 310 mOsm: Serum osmolarity measures the concentration of particles in the blood. In dehydration, the blood becomes more concentrated, leading to increased serum osmolarity. When treatment is effective, rehydration occurs, diluting the blood and bringing serum osmolarity back toward normal levels. Therefore, a decrease in serum osmolarity towards the normal range (280-300 mOsm) would indicate effective treatment of dehydration
Correct Answer is ["60"]
Explanation
1.Convert the available lidocaine concentration to mg/mL:
2 g of lidocaine = 2000 mg
2000 mg ÷ 500 mL = 4 mg/mL
2. Determine the mL/min required to deliver 4 mg/min:
4 mg/min ÷ 4 mg/mL = 1 mL/min
3. Convert mL/min to mL/hr:
1 mL/min × 60 minutes = 60 mL/hr
