1. 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.
2. A nurse is reviewing the health history of a client who has a prescription for Propranolol. Which of the following findings should the nurse report to the provider?
- A. Previous history of thromboembolism
- B. Concurrent use of an antacid
- C. History of bronchial asthma
- D. Recent weight gain
Correct answer: C
Rationale: Propranolol is a nonselective beta-blocker that can cause bronchoconstriction, making it contraindicated for clients with a history of bronchial asthma.
3. A patient has been taking hydrocodone, an opioid analgesic for their moderate pain, and they have taken more than the prescribed dose. What should you administer as the antidote if they experience toxicity?
- A. Naloxone
- B. N-acetylcysteine
- C. Atropine
- D. Digoxin immune Fab
Correct answer: A
Rationale: Naloxone is the specific antidote for opioid toxicity. It works by blocking the effects of opioids on the central nervous system, thereby reversing symptoms like respiratory depression and sedation. N-acetylcysteine is used for acetaminophen overdose, while atropine is indicated for certain types of poisonings. Digoxin immune Fab is used for digoxin toxicity. Therefore, in the case of opioid toxicity due to hydrocodone overdose, naloxone is the appropriate antidote.
4. A healthcare professional working in an emergency department is caring for a client who has Benzodiazepine toxicity due to an overdose. Which of the following actions is the healthcare professional's priority?
- A. Administer flumazenil.
- B. Identify the client's level of orientation.
- C. Infuse IV fluids.
- D. Prepare the client for gastric lavage.
Correct answer: B
Rationale: When managing a client with Benzodiazepine toxicity, the priority action for the healthcare professional is to assess the client. Identifying the client's level of orientation allows the healthcare professional to understand the client's cognitive status, which is crucial for further interventions and decision-making in the care plan. Administering flumazenil (Choice A) may precipitate withdrawal symptoms and should be done cautiously. Infusing IV fluids (Choice C) can be important but is not the priority over assessing the client. Gastric lavage (Choice D) is not typically recommended due to the risk of complications and its limited effectiveness in cases of Benzodiazepine overdose.
5. When teaching a client with a prescription for Loperamide for diarrhea, which instruction should the nurse include?
- A. Take the medication with a full glass of water.
- B. Avoid activities that require alertness.
- C. Expect abdominal pain and bloating.
- D. Take an additional dose after each loose stool.
Correct answer: B
Rationale: The correct instruction the nurse should include when teaching a client with a prescription for Loperamide is to 'Avoid activities that require alertness.' Loperamide can cause drowsiness, so clients should avoid such activities until they know how the medication affects them.
