Nursing Elites

1. A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)

• A. 0.8 mL
• B. 0.9 mL
• C. 10.0 mL
• D. 98.0 mL

Correct answer: A

Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.

2. When administering subcutaneous epinephrine for a client experiencing anaphylaxis, what adverse effect should the nurse monitor for?

• A. Hypotension
• B. Hyperthermia
• C. Hypoglycemia
• D. Tachycardia

Correct answer: D

Rationale: The correct adverse effect to monitor for when administering subcutaneous epinephrine for anaphylaxis is tachycardia. Epinephrine stimulates adrenergic receptors, leading to an increased heart rate (tachycardia). Hypotension (Choice A) is less likely due to the vasoconstrictive effects of epinephrine. Hyperthermia (Choice B) and hypoglycemia (Choice C) are not commonly associated with epinephrine administration for anaphylaxis.

3. A nurse is preparing to administer furosemide 4 mg/kg/day PO divided into 2 equal doses daily to a toddler who weighs 22 lb. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number)

• A. 20 mg
• B. 15 mg
• C. 10 mg
• D. 30 mg

Correct answer: A

Rationale: To calculate the dosage per dose, first, convert the toddler's weight from pounds to kilograms: 22 lb / 2.2 = 10 kg. Then, multiply the weight by the dosage: 4 mg × 10 kg = 40 mg/day. Since this total daily dose is divided into 2 equal doses, the nurse should administer 20 mg per dose. Therefore, the correct answer is 20 mg. Choice B (15 mg) is incorrect because it does not account for the correct weight conversion and dosage calculation. Choice C (10 mg) is incorrect as it only considers the weight conversion but doesn't multiply it by the dosage. Choice D (30 mg) is incorrect as it miscalculates the dosage by not dividing the total daily dose into 2 equal parts.

4. A nurse is preparing a discharge teaching plan for a client who is to begin long-term oral prednisone for asthma. Which of the following instructions should the nurse include in the plan?

• A. Stop taking the medication if a rash occurs.
• B. Take the medication on an empty stomach to enhance absorption.
• C. Schedule the medication on alternate days to decrease adverse effects.
• D. Treat shortness of breath with an extra dose of the medication.

Correct answer: C

Rationale: When initiating long-term oral prednisone therapy for asthma, it is essential to schedule the medication on alternate days. This approach helps reduce the risk of adverse effects commonly associated with corticosteroid use. Choice A is incorrect because abrupt discontinuation of prednisone can lead to adrenal insufficiency. Choice B is incorrect as prednisone should be taken with food to minimize gastrointestinal side effects. Choice D is incorrect because using an extra dose of prednisone to treat shortness of breath is not appropriate and can lead to overdosing.

5. A healthcare professional is planning to administer diltiazem via IV bolus to a client who has atrial fibrillation. When assessing the client, the healthcare professional should recognize that which of the following findings is a contraindication to the administration of diltiazem?

• A. Hypotension
• B. Tachycardia
• C. Decreased level of consciousness
• D. History of diuretic use

Correct answer: A

Rationale: Diltiazem, a calcium channel blocker, can cause hypotension. Administering it to a client who already has hypotension could exacerbate this condition. Therefore, hypotension is a contraindication to the administration of diltiazem. Incorrect Choices: B) Tachycardia is not a contraindication for administering diltiazem in atrial fibrillation as it is commonly used to control the heart rate. C) Decreased level of consciousness may require evaluation but is not a direct contraindication to diltiazem administration. D) History of diuretic use is not a contraindication if the client is not currently experiencing hypotension.
