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.
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 A
Explanation
Answer: A. Diplopia.
Rationale:
A) Diplopia: Diplopia, or double vision, is a common symptom in multiple sclerosis (MS) due to demyelination of nerves in the brainstem, affecting eye movement coordination. This visual disturbance is frequently seen in MS clients and may worsen during flare-ups.
B) Masklike expression: A masklike expression is more commonly associated with Parkinson’s disease rather than multiple sclerosis. This characteristic facial appearance is due to muscle rigidity, which is not typically a manifestation of MS.
C) Twitching of the face: Facial twitching, or fasciculations, is not typically a primary symptom of multiple sclerosis. While muscle weakness and spasticity are common in MS, twitching is more commonly seen in conditions such as amyotrophic lateral sclerosis (ALS).
D) Agitation: Agitation is not a primary symptom of MS. While MS can lead to cognitive changes or mood disturbances, such as depression, severe agitation is more commonly linked with other neurological or psychiatric conditions.
Correct Answer is C
Explanation
Choice A rationale:
Assessing the need for oral suction every 4 hours is essential in maintaining airway patency and preventing complications associated with excessive secretions. This is an appropriate action and does not require clarification.
Choice B rationale:
Checking the ventilator settings every 12 hours is necessary to ensure that the mechanical ventilation is providing adequate support for the client's respiratory needs. This prescription is appropriate and does not need clarification.
Choice C rationale:
Keeping the head of the client's bed elevated at 30° is important in preventing aspiration and ventilator-associated pneumonia. This position helps promote optimal lung expansion and improves oxygenation in ventilated clients.
Choice D rationale:
Performing oral hygiene using an alcohol-based oral rinse is not recommended for clients receiving mechanical ventilation. Alcohol-based products can be harmful if aspirated and may disrupt the normal oral flora, leading to complications. The nurse should use a non-alcohol-based oral rinse or foam swabs instead.
