Nursing Elites

1. A healthcare professional is preparing to administer heparin 15,000 units subcutaneously every 12 hours. The available heparin injection is 20,000 units/mL. How many milliliters should the healthcare professional administer per dose?

• A. 0.8 mL
• B. 0.75 mL
• C. 0.5 mL
• D. 1 mL

Correct answer: A

Rationale: To calculate the volume to administer, use the formula: Desired dose / Concentration = Volume to administer. In this case, (15,000 units / 20,000 units/mL) = 0.75 mL. Since the volume needs to be rounded up to the nearest tenth, the correct answer is 0.8 mL. Choice B (0.75 mL) is incorrect because it does not account for rounding up the volume. Choices C (0.5 mL) and D (1 mL) are incorrect as they do not reflect the precise calculation based on the given concentration and desired dose.

2. A drug ending in the suffix (tidine) is considered a ______.

• A. Antidepressant
• B. Protease inhibitor
• C. Beta antagonist
• D. H antagonist

Correct answer: D

Rationale: Drugs ending in -tidine are histamine (H2) receptor antagonists, which block the action of histamine at the H2 receptors, commonly used to reduce stomach acid production. Therefore, the correct answer is an 'H antagonist.' It is essential to be familiar with drug suffixes as they can provide clues to the drug's class and function.

3. A client has a new prescription for Cyclobenzaprine to treat muscle spasms. Which of the following instructions should the nurse include in the teaching?

• A. Avoid driving or operating heavy machinery while taking this medication.
• B. Take this medication on an empty stomach for best results.
• C. Take this medication only when experiencing muscle pain.
• D. Increase your intake of potassium-rich foods while taking this medication.

Correct answer: A

Rationale: The correct instruction that the nurse should include in the teaching for a client prescribed Cyclobenzaprine is to avoid driving or operating heavy machinery while taking this medication. Cyclobenzaprine can cause drowsiness, so it is important to advise clients to avoid activities that require alertness and coordination to prevent accidents or injuries. Choice B is incorrect because Cyclobenzaprine can be taken with or without food. Choice C is incorrect because Cyclobenzaprine is typically taken regularly as prescribed, not just when experiencing muscle pain. Choice D is incorrect because there is no specific need to increase potassium-rich foods while taking Cyclobenzaprine.

4. When teaching a client with a new prescription for Sulfasalazine, which instruction should the nurse include?

• A. Expect orange discoloration of urine and skin.
• B. Increase your intake of high-sodium foods.
• C. Take the medication with a full glass of milk.
• D. Expect your stools to be black and tarry.

Correct answer: A

Rationale: The correct instruction to include when teaching a client with a new prescription for Sulfasalazine is to expect orange discoloration of urine and skin. Sulfasalazine can cause this harmless side effect, which does not necessitate discontinuation of the medication. It is crucial for the nurse to educate the client about this expected outcome to prevent unnecessary concern or discontinuation of the medication. Choices B, C, and D are incorrect. Increasing intake of high-sodium foods is not recommended with Sulfasalazine, as it can worsen certain side effects. Taking the medication with a full glass of milk is not necessary for Sulfasalazine administration. Expecting stools to be black and tarry is not an expected side effect of Sulfasalazine.

5. A healthcare professional reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the professional take?

• A. Obtain a blood specimen immediately prior to administering the next dose of medication.
• B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
• C. Ask the client to provide a urine specimen after the next dose of medication.
• D. Administer the medication, and obtain a blood specimen 30 minutes later.

Correct answer: A

Rationale: To verify trough levels of a medication, the healthcare professional should obtain a blood specimen immediately before administering the next dose of medication. This timing ensures an accurate representation of the medication's lowest concentration in the bloodstream, which is crucial for therapeutic monitoring and dose adjustments. Choice B is incorrect because waiting 24 hours after taking the medication would not provide an accurate trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect because obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level, as it is the lowest concentration before the next dose.
