A nurse is caring for a client who is to start therapy with lovastatin.
The nurse should prepare the client for which of the following diagnostic assessments?
Western blot analysis.
Pancreatic enzymes.
Exercise electrocardiography.
Liver function tests.
The Correct Answer is D
Lovastatin is a lipid-lowering medication that belongs to the statin drug class.
It is used to treat and prevent coronary heart disease and hypercholesterolemia.
Before starting therapy with lovastatin, liver function tests should be performed to establish a baseline and monitor for any potential adverse effects on the liver.
Choice A is wrong because Western blot analysis, is not the correct answer because it is a laboratory technique used to detect specific proteins in a sample, not to monitor liver function.
Choice B is wrong because Pancreatic enzymes, is not the correct answer because it refers to enzymes produced by the pancreas that aid in digestion, not liver function.
Choice C is wrong because Exercise electrocardiography, is not the correct answer because it is a diagnostic test used to assess the heart’s response to physical stress, not liver function.

Correct Answer is B
Explanation
Osmotic laxatives work by drawing water into the intestines, which can lead to fluid loss and dehydration if not enough fluids are consumed.
Oliguria, or decreased urine output, can be a sign of fluid volume deficit and dehydration.
Choice A is wrong because Weight gain, is not an indication of fluid volume deficit as weight loss is more commonly associated with dehydration.
Choice C is wrong because Headaches, can be a symptom of dehydration but is not specific to fluid volume deficit.
Choice D is wrong because Nausea, can also be a symptom of dehydration but is not specific to fluid volume deficit.
Correct Answer is C
Explanation
- A. Assist the client to a left lateral position.
- This is generally used for clients at risk of aspiration, and it's not indicated based on the lithium level.
- B. Implement fluid restrictions.
- Fluid restrictions are usually implemented when there is a risk of fluid overload or hyponatremia, and not in this case. In fact, dehydration can raise lithium levels to toxic levels, so proper hydration is important.
- C. Request a dosage increase from the provider.
- While 0.6 mEq/L is within the therapeutic range, some providers may want to see a level slightly higher for maintenance. So requesting a dosage increase from the provider is the correct action.
- D. Prepare the client for hemodialysis.
- Hemodialysis is used to remove lithium from the blood in cases of severe lithium toxicity, which is indicated by levels significantly higher than 1.5 mEq/L. This is not needed when the lithium level is 0.6 mEq/L.
