A nurse is teaching a client who has a new prescription for lovastatin. Which of the following diagnostic tests should the nurse instruct the client to complete before starting the medication?

Potassium level.

Hemoglobin level.

Kidney function tests.

Liver function tests.

Answer and Explanation

The Correct Answer is D

Choice A rationale:
(Potassium level) Lovastatin is a medication used to treat high cholesterol levels. While potassium levels are important to monitor for certain conditions, they are not directly related to the initiation of lovastatin therapy. Therefore, this is not the correct choice for diagnostic testing before starting the medication.
Choice B rationale:
(Hemoglobin level) Hemoglobin levels are important to assess for anemia or other blood disorders. However, they are not specifically required before starting lovastatin therapy. Therefore, this is not the correct choice for diagnostic testing before starting the medication.
Choice C rationale:
(Kidney function tests) While kidney function tests are essential for many medications to ensure proper excretion and avoid toxicity, they are not directly related to the initiation of lovastatin therapy. Therefore, this is not the correct choice for diagnostic testing before starting the medication.
Choice D rationale:
(Liver function tests) Liver function tests are crucial before starting lovastatin therapy. Lovastatin is metabolized in the liver, and it can potentially cause liver damage or abnormalities in liver enzymes. Monitoring liver function helps detect any pre-existing liver conditions and ensures the safe use of the medication. Therefore, this is the correct choice for diagnostic testing before starting the medication.

Correct Answer is B

Explanation

Let's break down the calculation:

Given:

Patient weight: 154 lbs
Enoxaparin dosage: 0.75 mg/kg
Available enoxaparin: 60 mg/0.6 mL

Step 1: Convert pounds to kilograms:

1 lb is approximately 0.4536 kg
So, 154 lbs = 154 * 0.4536 kg/lb = 69.85 kg (approximately 70 kg)

Step 2: Calculate the total dose of enoxaparin:

Desired dose = 0.75 mg/kg * 70 kg = 52.5 mg

Step 3: Determine the volume to administer:

We have enoxaparin 60 mg/0.6 mL
To find the volume for 52.5 mg:
- (52.5 mg / 60 mg) * 0.6 mL = 0.525 mL
- Rounded to the nearest tenth, this is 0.5mL.

Therefore, the nurse should administer 0.5mL of enoxaparin

A. Left leg is warm to the touch. B. Left pedal pulse strength is 2. C. The client reports pain in the foot of the left leg. D. Capillary refill in the left foot is 3 seconds.

Correct Answer is D

Explanation

Choice A rationale:
A warm left leg is a normal finding and does not require immediate intervention. Warmth indicates adequate circulation to the limb.
Choice B rationale:
A pedal pulse strength of 2 in the left leg indicates diminished pulse but does not require immediate intervention. The nurse should continue to monitor the pulse and report any significant changes to the healthcare provider.
Choice C rationale:
The client's report of pain in the foot of the left leg is an expected finding due to the fractured left femur. Pain is a subjective symptom, and the nurse should address the client's pain appropriately but not intervene immediately based on this finding.
Choice D rationale:
This is the correct choice. A capillary refill time of 3 seconds in the left foot suggests impaired circulation, which could be indicative of compartment syndrome or other circulation-related issues. The nurse should intervene immediately by notifying the healthcare provider to prevent further complications.
