Which laboratory value should the nurse review prior to administering the initial dose of a statin medication?

Complete blood count.

Serum electrolytes.

Capillary blood glucose.

Serum liver enzymes.

Answer and Explanation

The Correct Answer is D

Choice A reason: A complete blood count (CBC) is not typically required before starting statin therapy. While a CBC can provide valuable information about a patient’s overall health, it does not specifically relate to the potential side effects or necessary monitoring for statin use. Statins primarily affect the liver, so monitoring liver function is more critical.

Choice B reason: Serum electrolytes are important for assessing overall metabolic and kidney function, but they are not directly related to the initiation of statin therapy. Statins do not typically affect electrolyte levels, so this test is not necessary before starting the medication.

Choice C reason: Capillary blood glucose levels are important for monitoring diabetes and blood sugar control. While statins can have an impact on blood glucose levels, this is not the primary concern when initiating therapy. Monitoring liver function is more directly related to the potential side effects of statins.

Choice D reason: Serum liver enzymes are crucial to review before starting statin therapy. Statins can cause liver enzyme elevations, indicating liver damage or dysfunction. Therefore, baseline liver enzyme levels should be obtained to monitor for any potential hepatotoxicity during treatment.

Correct Answer is C

Explanation

Choice A reason:

Teaching the client about foods high in calcium is important, but it is not the most immediate action required. A serum calcium level of 5.5 mg/dL is significantly below the normal range (8.5-10.2 mg/dL) and indicates severe hypocalcemia. While dietary education is beneficial for long-term management, the nurse must first address the acute issue by notifying the healthcare provider.

Choice B reason:

Beginning to taper the drug dose per protocol is not appropriate without consulting the healthcare provider. Methylprednisolone, a corticosteroid, can cause decreased calcium absorption and increased calcium excretion. However, any changes to the medication regimen should be directed by the healthcare provider, especially in the context of severe hypocalcemia.

Choice C reason:

Notifying the healthcare provider of the finding is the most critical action. Severe hypocalcemia can lead to serious complications such as cardiac arrhythmias, muscle spasms, and seizures. Immediate medical intervention is necessary to correct the calcium imbalance and prevent potential life-threatening conditions.

Choice D reason:

Administering the medication with a glass of milk is not sufficient to address the severe hypocalcemia. While milk contains calcium, the amount is not enough to correct a serum calcium level as low as 5.5 mg/dL. The nurse must prioritize notifying the healthcare provider to ensure appropriate treatment is initiated.

A. Insomnia may occur while taking the medication. B. Another form of contraception is not needed. C. Sensitivity to the sun can develop. D. Hard candy can be used for a dry mouth.

Correct Answer is B

Explanation

Choice A reason:

Insomnia is a known side effect of St. John’s wort. While it can be bothersome, it does not typically require further instruction beyond standard advice on managing insomnia. Patients should be advised to take the medication earlier in the day to minimize sleep disturbances.

Choice B reason:

St. John’s wort can interact with hormonal contraceptives, reducing their effectiveness and increasing the risk of unintended pregnancy. This interaction occurs because St. John’s wort induces the enzymes that metabolize contraceptive hormones, leading to lower levels of these hormones in the body. Therefore, it is crucial to instruct the client to use an additional form of contraception to prevent pregnancy.

Choice C reason:

Sensitivity to the sun, or photosensitivity, is a documented side effect of St. John’s wort. Patients should be advised to use sunscreen and wear protective clothing when exposed to sunlight. While this side effect requires caution, it does not necessitate further instruction beyond these preventive measures.

Choice D reason:

Using hard candy to alleviate dry mouth is a common and effective strategy. St. John’s wort can cause dry mouth, and sucking on sugar-free hard candy can help stimulate saliva production. This advice is appropriate and does not require further instruction.
