Nursing Elites

1. A client has a new prescription for Losartan. Which of the following laboratory values should the nurse monitor?

• A. Serum potassium
• B. Serum sodium
• C. Serum calcium
• D. Serum magnesium

Correct answer: A

Rationale: Corrected Rationale: Losartan, an angiotensin II receptor blocker (ARB), can cause hyperkalemia. The nurse should monitor the client's serum potassium levels closely because Losartan can increase potassium levels, potentially leading to serious complications such as arrhythmias. Monitoring serum sodium, calcium, or magnesium levels is not typically necessary when a patient is prescribed Losartan, as these values are not directly affected by this medication.

2. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?

• A. Spironolactone
• B. Furosemide
• C. Hydrochlorothiazide
• D. Bumetanide

Correct answer: A

Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.

3. A client has a new prescription for Hydralazine. Which of the following side effects should the nurse instruct the client to monitor for and report?

• A. Orthostatic hypotension
• B. Increased heart rate
• C. Dark-colored urine
• D. Persistent cough

Correct answer: B

Rationale: Corrected Rationale: Hydralazine, a vasodilator, can cause reflex tachycardia, leading to an increased heart rate. This side effect should be reported to the healthcare provider to ensure appropriate management and monitoring of the client's condition. Choice A (Orthostatic hypotension) is incorrect as Hydralazine is more likely to cause reflex tachycardia than orthostatic hypotension. Choice C (Dark-colored urine) and Choice D (Persistent cough) are unrelated to the common side effects of Hydralazine and should not be the focus of monitoring for this medication.

4. What are the Therapeutic Effects of Lithium?

• A. Prevents or decreases the incidence of acute manic episodes
• B. Maintenance of blood glucose
• C. Control of hyperglycemia in diabetic patients
• D. Diminished seizure activity

Correct answer: A

Rationale: The therapeutic effect of lithium is that it prevents or decreases the incidence of acute manic episodes in patients with bipolar disorder. Lithium is commonly used as a mood stabilizer in the treatment of bipolar disorder due to its ability to reduce the frequency and severity of manic episodes. Choices B, C, and D are incorrect as lithium is not used for the maintenance of blood glucose, control of hyperglycemia in diabetic patients, or to diminish seizure activity. These effects are not associated with the use of lithium as a medication.

5. A child is prescribed Amoxicillin 20 mg/kg/day PO to be administered every 12 hr. The child weighs 44 lb. The available medication is amoxicillin suspension 250 mg/5 mL. How many mL should be given per dose?

• A. 4 mL
• B. 5 mL
• C. 6 mL
• D. 3 mL

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.
