Nursing Elites

1. The healthcare provider prescribes furosemide (Lasix) 15 mg IV stat. On hand is Lasix 20 mg/2 ml. How many milliliters should the LPN/LVN administer?

• A. 1 ml.
• B. 1.5 ml.
• C. 1.75 ml.
• D. 2 ml.

Correct answer: B

Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.

2. The nurse has admitted a 4-year-old with the diagnosis of possible rheumatic fever. Which statement by the parent would cause the nurse to suspect an association with this disease?

• A. Our child had chickenpox 6 months ago.
• B. Strep throat went through all the children at the day care last month.
• C. Both ears were infected over 3 months ago.
• D. Last week both feet had a fungal skin infection.

Correct answer: B

Rationale: The correct answer is B. Rheumatic fever often follows a strep throat infection, which is why the nurse should suspect this association. Strep throat is caused by Group A Streptococcus bacteria, which can trigger an abnormal immune response leading to rheumatic fever. Choices A, C, and D are incorrect because chickenpox, ear infections, and fungal skin infections are not typically associated with rheumatic fever.

3. A nurse is preparing to administer methylprednisolone 10 mg by IV bolus. The amount available is methylprednisolone injection 40-mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Do not use a trailing zero.)

• A. 0.3 mL
• B. 0.25 mL
• C. 0.4 mL
• D. 0.5 mL

Correct answer: A

Rationale: To calculate the mL to administer, use the formula: Dose required (mg) ÷ Stock concentration (mg/mL) = Volume to administer (mL). In this case, 10 mg ÷ 40 mg/mL = 0.25 mL. However, when rounding to the nearest tenth, the answer should be 0.3 mL. Therefore, the nurse should administer 0.3 mL. Choice A is the correct answer. Choice B (0.25 mL) is the result obtained before rounding. Choice C (0.4 mL) and Choice D (0.5 mL) are incorrect calculations.

4. The healthcare professional is evaluating the body alignment of a patient in the sitting position. Which observation will indicate a normal finding?

• A. The edge of the seat is making contact with the popliteal space.
• B. Both feet are supported on the floor with ankles flexed.
• C. The body weight is solely on the buttocks.
• D. The arms hang comfortably at the sides.

Correct answer: B

Rationale: In a normal sitting position, both feet should be supported on the floor with the ankles comfortably flexed. This position helps in maintaining stability and proper alignment. Choice A is incorrect because the edge of the seat pressing against the popliteal space may cause discomfort and is not indicative of proper alignment. Choice C is incorrect as the body weight should be evenly distributed for proper alignment and comfort, not solely on the buttocks. Choice D is incorrect as the position of the arms alone does not indicate proper body alignment in the sitting position; proper arm positioning is important for comfort but not a key indicator of body alignment.

5. When assessing a male client, the nurse finds that he is fatigued and is experiencing muscle weakness, leg cramps, and cardiac dysrhythmias. Based on these findings, the nurse plans to check the client's laboratory values to validate the existence of which condition?

• A. Hyperphosphatemia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hypokalemia

Correct answer: D

Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.
