A healthcare professional is caring for a client who has a new prescription for Lisinopril. Which of the following laboratory values should the professional monitor?

Correct Answer: A

Rationale: Lisinopril is an ACE inhibitor that can cause hyperkalemia by reducing the excretion of potassium in the kidneys. Monitoring serum potassium levels is essential to prevent complications such as cardiac arrhythmias. Therefore, the healthcare professional should closely monitor the client's serum potassium levels when they are on Lisinopril. Choices B, C, and D are incorrect because Lisinopril primarily affects potassium levels due to its mechanism of action as an ACE inhibitor. Serum sodium, calcium, and magnesium levels are not typically affected by Lisinopril in the same way as potassium.

Correct Answer: D

Rationale: Hydrochlorothiazide is a diuretic that can lead to dehydration due to increased urination. Signs of dehydration include dry mouth, increased thirst, and decreased urine output. It is essential to educate the client to monitor these signs and seek medical attention if they occur. Choice A is incorrect because Hydrochlorothiazide is usually taken in the morning to prevent disruption of sleep due to increased urination during the night. Choice B is incorrect because while Hydrochlorothiazide can lead to potassium loss, consuming foods rich in potassium is not a specific instruction related to this medication. Choice C is incorrect because taking Hydrochlorothiazide with a meal is not a specific requirement for its administration.

Correct Answer: A

Rationale: Phenobarbital, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.

Correct Answer: B

Rationale: The correct answer is B: 'Another nurse should listen to the phone call.' When taking a telephone prescription, having another nurse listen to the phone call is essential to prevent errors in communication. This process helps ensure accuracy and reduces the risk of misinterpretation. Choice A is incorrect because entering the prescription into the client's medical record is not related to verifying the accuracy of the telephone prescription. Choice C is incorrect as the provider clarifying the prescription upon signing the health record doesn't address the immediate need for verification during the phone call. Choice D is incorrect because the 'read back' is a crucial step in confirming the accuracy of all prescriptions, regardless of whether they are one-time or recurring.

Correct Answer: A

Rationale: To calculate the dosage per administration: Convert the weight to kg (44 lb / 2.2 lb/kg = 20 kg). Then, (20 mg/kg/day x 20 kg) / 2 (for every 12 hr dosing) = 200 mg per dose. (200 mg / 250 mg) x 5 mL = 4 mL per dose. Therefore, the nurse should administer 4 mL of amoxicillin suspension per dose. Choice B, 5 mL, is incorrect because the calculation shows that 4 mL is the correct dose. Choices C and D are also incorrect as they are not in line with the calculated dosage based on the weight of the child and the concentration of the medication.
