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 client has a new prescription for Atorvastatin. Which of the following instructions should the nurse include?

• A. Avoid drinking grapefruit juice.
• B. Take the medication with your evening meal.
• C. Increase your intake of leafy green vegetables.
• D. Stop taking the medication if you experience muscle pain.

Correct answer: A

Rationale: The correct answer is A: 'Avoid drinking grapefruit juice.' Grapefruit juice should be avoided when taking Atorvastatin because it can increase the blood levels of the medication, potentially leading to a higher risk of adverse effects like muscle pain and liver damage. It is important to follow this instruction to ensure the safe and effective use of Atorvastatin. Choices B, C, and D are incorrect. Taking Atorvastatin with food, specifically a low-fat meal, is recommended, but it is not necessary to specify the evening meal. While increasing intake of leafy green vegetables is generally beneficial for health, it is not a specific instruction for Atorvastatin. Lastly, stopping the medication if one experiences muscle pain is not advisable without consulting a healthcare provider, as muscle pain can be a symptom of a serious side effect of Atorvastatin that requires medical attention.

3. What is the therapeutic use of Alprazolam?

• A. Preventing thrombus formation
• B. Relief of anxiety
• C. Decreasing the risk of stroke
• D. Increasing urinary output

Correct answer: B

Rationale: The therapeutic use of Alprazolam is for the relief of anxiety. Alprazolam belongs to a class of medications known as benzodiazepines, which are commonly prescribed to manage anxiety disorders and panic attacks. It works by enhancing the effects of a natural chemical in the body (GABA) to produce a calming effect on the brain and nerves, thereby alleviating symptoms of anxiety.

4. A client has a new prescription for Methotrexate to treat Rheumatoid Arthritis. Which of the following instructions should the nurse provide?

• A. Take this medication with food to prevent nausea.
• B. Drink plenty of fluids to stay hydrated while on this medication.
• C. Avoid alcohol while taking this medication.
• D. Wear sunscreen when outdoors while taking this medication.

Correct answer: C

Rationale: The correct instruction for a client taking Methotrexate is to avoid alcohol, as it can increase the risk of liver damage. Alcohol consumption should be avoided to prevent potential adverse effects while on this medication.

5. A client has a new prescription for clonidine to treat hypertension. Which of the following instructions should the nurse include?

• A. Discontinue the medication if a rash develops.
• B. Expect increased salivation during the first few weeks of therapy.
• C. Avoid driving until the client's reaction to the medication is known.
• D. Stop the medication if you experience a dry mouth.

Correct answer: C

Rationale: The correct instruction for a client starting clonidine therapy for hypertension is to avoid driving until their reaction to the medication is known. Clonidine can cause drowsiness, so engaging in activities like driving that require alertness should be avoided until the individual understands how the medication affects them. Choices A, B, and D are incorrect because they do not address the specific side effect of drowsiness associated with clonidine that could impair driving abilities. Discontinuing the medication if a rash develops, expecting increased salivation, or stopping the medication for dry mouth are not primary concerns related to clonidine therapy for hypertension.
