A preschooler weighing 44 lb is to receive Amoxicillin 20 mg/kg/day PO divided equally every 12 hr. The available amoxicillin suspension is 250 mg/5 mL. How many mL should the nurse administer per dose?
- A. 4 mL
- B. 5 mL
- C. 6 mL
- D. 3 mL
Correct Answer: A
Rationale: To calculate the dosage per administration: First, convert the weight to kg (44 lb / 2.2 lb/kg = 20 kg). Then, calculate the required dosage per dose: (20 mg/kg/day x 20 kg) / 2 (for every 12 hr dosing) = 200 mg per dose. To determine the mL per dose, divide the required dosage by the concentration of the amoxicillin suspension: (200 mg / 250 mg) x 5 mL = 4 mL per dose. Therefore, the correct answer is 4 mL. Choice B (5 mL) is incorrect because the correct calculation yields 4 mL. Choices C (6 mL) and D (3 mL) are also incorrect as they do not align with the accurate calculation based on the provided information.

A healthcare professional is reviewing a client's medication history and notes a new prescription for Enalapril. The healthcare professional should monitor the client for which of the following as an adverse effect of this medication?
- A. Bradycardia
- B. Hyperkalemia
- C. Hypoglycemia
- D. Hypocalcemia
Correct Answer: B
Rationale: Enalapril, an ACE inhibitor, can cause hyperkalemia as an adverse effect due to decreased aldosterone levels, which leads to potassium retention. Monitoring potassium levels is essential to prevent potential complications associated with hyperkalemia. The other options, bradycardia, hypoglycemia, and hypocalcemia, are not typically associated with Enalapril use and are less likely to occur as adverse effects.
A client is receiving treatment with vincristine. Which of the following findings should the nurse monitor?
- A. Hyperkalemia
- B. Neurotoxicity
- C. Neutropenia
- D. Bradycardia
Correct Answer: B
Rationale: The correct answer is B: Neurotoxicity. Vincristine is known to cause neurotoxicity as an adverse effect due to its impact on the nervous system. Monitoring for neurotoxicity is crucial to detect any signs early. Choices A, C, and D are incorrect. Hyperkalemia is not a typical finding associated with vincristine. Neutropenia is a common side effect of chemotherapy but is not directly related to vincristine. Bradycardia is not a common adverse effect of vincristine.
A client has a new prescription for Captopril for hypertension. The nurse should monitor the client for which of the following adverse effects of this medication?
- A. Hypokalemia
- B. Hypernatremia
- C. Neutropenia
- D. Bradycardia
Correct Answer: C
Rationale: Neutropenia is a serious adverse effect associated with ACE inhibitors like Captopril. Neutropenia refers to a decreased level of neutrophils, which are important white blood cells in fighting infection. Monitoring the client's complete blood count (CBC) is essential to detect neutropenia early. Hypokalemia (Choice A) is more commonly associated with diuretics, not ACE inhibitors. Hypernatremia (Choice B) is an increase in sodium levels, not typically caused by Captopril. Bradycardia (Choice D) is not a common adverse effect of ACE inhibitors like Captopril.
A nurse is providing discharge instructions to a client who has a new prescription for a Fentanyl transdermal patch. Which of the following instructions should the nurse include?
- A. Apply the patch to a hairy area.
- B. Change the patch every 24 hours.
- C. Avoid exposure to heat sources.
- D. Cut the patch to adjust the dosage.
Correct Answer: C
Rationale: The correct instruction that the nurse should include when providing discharge instructions for a client with a Fentanyl transdermal patch is to avoid exposure to heat sources. Heat can increase the absorption of the medication, leading to a risk of overdose. Choice A is incorrect because the patch should be applied to a clean, non-hairy area. Choice B is incorrect as the Fentanyl patch is usually changed every 72 hours, not every 24 hours. Choice D is incorrect as the patch should never be cut to adjust the dosage.
While assessing a client taking Amiodarone to treat Atrial Fibrillation, which of the following findings is indicative of Amiodarone toxicity?
- A. Light yellow urine
- B. Report of tinnitus
- C. Productive cough
- D. Blue-gray skin discoloration
Correct Answer: C
Rationale: Productive cough can indicate pulmonary toxicity, which is a known adverse effect of Amiodarone. Clients on Amiodarone should be monitored for signs of pulmonary toxicity such as cough, dyspnea, and chest pain. This is important to detect early and prevent serious complications. The other options are not typically associated with Amiodarone toxicity. Light yellow urine is not a common sign, tinnitus is more related to ear problems, and blue-gray skin discoloration is not a recognized symptom of Amiodarone toxicity.
