Nursing Elites

1. The client with congestive heart failure (CHF) is receiving furosemide (Lasix). Which laboratory value should the healthcare provider monitor closely?

• A. Potassium
• B. Sodium
• C. Calcium
• D. Magnesium

Correct answer: A

Rationale: Correct! When a client is taking furosemide (Lasix), monitoring potassium levels is crucial due to the potential for hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss through increased urine output. Low potassium levels can predispose the client to cardiac dysrhythmias. Sodium, calcium, and magnesium levels are not typically affected by furosemide to the same extent as potassium, making them less critical to monitor in this scenario.

2. Seconal 0.1 gram PRN at bedtime is prescribed to a client for rest. The scored tablets are labeled 1.5 grains per tablet. How many tablets should the LPN/LVN plan to administer?

• A. 0.5 tablet
• B. 1 tablet
• C. 1.5 tablets
• D. 2 tablets

Correct answer: B

Rationale: To calculate the number of tablets needed, convert the prescribed dose of Seconal from grams to grains. Since 1 gram is equal to approximately 15.43 grains, 0.1 gram is roughly 1.543 grains. Given that each tablet contains 1.5 grains, administering 1 tablet (which is slightly more than the 1.543 grains needed) provides the correct dose of Seconal. Therefore, the LPN/LVN should plan to administer 1 tablet. Choice A (0.5 tablet) is incorrect as it would provide less than the required dose. Choice C (1.5 tablets) and Choice D (2 tablets) are incorrect as they would exceed the necessary dosage.

3. A healthcare professional in a provider's office is reviewing the laboratory findings of a client who reports chills and aching joints. Which of the following findings should the healthcare professional identify as an indication that the client has an infection?

• A. WBC 15,000/mm³
• B. Hemoglobin 12 g/dL
• C. Platelet count 300,000/mm³
• D. Sodium 140 mEq/L

Correct answer: A

Rationale: An elevated white blood cell count (WBC 15,000/mm³) is a common indicator of infection as the body increases WBC production to fight off pathogens. In conditions like infections, inflammation, or stress, the WBC count can rise. The other options, hemoglobin, platelet count, and sodium levels, are not typically specific indicators of infection. Hemoglobin measures the oxygen-carrying capacity of red blood cells, platelet count assesses clotting ability, and sodium levels indicate electrolyte balance.

4. A client who has a new prescription for warfarin (Coumadin) is receiving discharge instructions. Which statement indicates the client understands the teaching?

• A. I will take my warfarin at the same time every day.
• B. I should increase my intake of green leafy vegetables.
• C. I should use a soft-bristled toothbrush while taking this medication.
• D. I should avoid drinking alcohol while taking this medication.

Correct answer: C

Rationale: The correct answer is C: 'I should use a soft-bristled toothbrush while taking this medication.' Using a soft-bristled toothbrush is crucial as it helps prevent bleeding gums, which is a potential side effect of warfarin therapy. Option A about taking warfarin at the same time every day is a good practice but does not directly relate to preventing side effects. Option B suggesting an increase in green leafy vegetables can interfere with warfarin's anticoagulant effects due to their vitamin K content. Option D advising to avoid alcohol is generally recommended but is not directly related to the specific side effects of warfarin.

5. While measuring a client’s oral temperature using an electronic thermometer, what action should the nurse take?

• A. Assist the client with oral hygiene before taking the temperature.
• B. Inquire whether the client has smoked in the last 30 minutes.
• C. Connect the red tip probe to the thermometer unit.
• D. Position the probe tip against the client’s buccal mucosa.

Correct answer: B

Rationale: The correct action for the nurse to take when measuring a client’s oral temperature using an electronic thermometer is to inquire whether the client has smoked in the last 30 minutes. Smoking can affect the accuracy of oral temperature readings. Providing oral hygiene (Choice A) is not directly related to ensuring accurate temperature measurement. Connecting the red tip probe (Choice C) is not specific to oral temperature measurement accuracy. Positioning the probe tip against the buccal mucosa (Choice D) is incorrect as oral temperature is typically measured under the tongue, not against the cheek.
