Which of these comments by a client taking a calcium channel blocker would indicate the need for additional teaching?
"I will rise slowly from lying to sitting, to standing."
"I will elevate my legs if edema occurs."
"I will take the medication with grapefruit juice.”
"I can limit my risk for constipation by increasing fluid and fiber."
The Correct Answer is C
a) Rising slowly from lying to sitting and standing is a precaution to prevent orthostatic hypotension, a potential side effect of calcium channel blockers.
b) Elevating legs if edema occurs is a reasonable response to manage peripheral edema associated with calcium channel blockers.
c) Grapefruit juice can interact with calcium channel blockers, leading to increased drug levels and potential toxicity. This statement indicates a need for additional teaching.
d) Increasing fluid and fiber to limit the risk of constipation is a reasonable measure associated with the use of calcium channel blockers.

Correct Answer is B
Explanation
a) Vitamin D levels may be affected by long-term glucocorticoid use, but the described symptoms are more indicative of potential glucocorticoid-related side effects, such as Cushingoid features, which warrant liver function tests.
b) Liver function tests are appropriate to assess the impact of long-term glucocorticoid use on the liver, as these medications can affect liver function.
c) Serum electrolytes are important to monitor, but the specific symptoms mentioned (full cheeks, hump of fat) are not typically associated with electrolyte imbalances.
d) A tuberculin skin test is unrelated to the observed symptoms and is not typically ordered based on the physical features described.
Correct Answer is D
Explanation
a) While the negative feedback loop plays a role in the body's natural regulation of corticosteroids, it does not eliminate the potential for side effects when exogenous glucocorticoids are administered.
b) Taking the drug as prescribed does not guarantee the absence of side effects. Side effects are inherent to glucocorticoid therapy and can occur even with appropriate use.
c) Interrupting the inflammatory process does not directly inhibit side effects. The anti inflammatory action is the therapeutic effect, but it does not eliminate the potential for side effects.
d) Glucocorticoids, even those produced naturally by the body, can cause side effects, and the likelihood and severity of these side effects depend on the dose and duration of treatment. Regular monitoring and appropriate management are essential.
