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?

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 staff educator is reviewing medication dosages and factors that influence medication metabolism with a group of nurses at an in-service presentation. Which of the following factors should the educator include as a reason to administer lower medication dosages? (Select all that apply.)

Correct answer: C

Rationale: Liver failure impairs metabolism, leading to increased medication concentrations. When liver function is compromised, lower dosages are necessary to prevent adverse effects. Increased renal secretion is not a reason for lower medication dosages, as it primarily affects excretion rather than metabolism. Increased medication-metabolizing enzymes would usually require higher dosages to achieve the desired effect. Peripheral vascular disease does not directly impact medication metabolism or dosage requirements.

3. A client is reviewing a new prescription for Terbutaline with a history of preterm labor. Which of the following client statements indicates understanding of the teaching?

Correct answer: C

Rationale: The correct answer is C. The client should report increasing intensity, frequency, or duration of contractions to the provider as these are signs of preterm labor. Monitoring contractions is crucial for the management of preterm labor and the safety of both the client and the fetus. Choices A, B, and D are incorrect because increasing activity, fluid intake, or assuming the medication will prevent preterm labor do not address the essential need to report changes in contractions, which are a vital sign of potential complications in preterm labor.

4. A healthcare provider is assessing a client who takes Lithium Carbonate for the treatment of Bipolar disorder. The provider should recognize which of the following findings as a possible indication of toxicity to this medication?

Correct answer: B

Rationale: Coarse tremors are a common sign of Lithium toxicity. It is important for healthcare providers to monitor for this symptom as it indicates a potential overdose of the medication. Severe hypertension, constipation, and muscle spasms are not typically associated with Lithium toxicity. Severe hypertension is not a common sign of Lithium toxicity but rather a symptom of hypertensive crisis. Constipation is not a typical sign of Lithium toxicity but could be seen in other conditions. Muscle spasms are not specific to Lithium toxicity but can occur due to various reasons.

5. A healthcare professional is preparing to administer Spironolactone to a client. Which of the following laboratory results should the professional review before administering this medication?

Correct answer: A

Rationale: When administering Spironolactone, it is essential to monitor the client's serum potassium levels because Spironolactone is a potassium-sparing diuretic. Monitoring potassium levels helps to detect hyperkalemia, a potential adverse effect of the medication.
