A nurse is educating a patient who has been prescribed Atorvastatin. Which of the following instructions should the nurse include in the patient teaching?
"You should see benefits within days of starting your atorvastatin."
"You may consume grapefruit juice freely while on this medication."
"Report any muscle pain, weakness, or tenderness to your healthcare provider immediately."
"You can use an NSAID prior to taking your atorvastatin to prevent flushing."
The Correct Answer is C
A. "You should see benefits within days of starting your atorvastatin.": Atorvastatin works by lowering LDL cholesterol, but measurable improvements in lipid levels typically take several weeks. Immediate effects are unlikely, and full benefits depend on adherence and time.
B. "You may consume grapefruit juice freely while on this medication.": Grapefruit juice inhibits CYP3A4 enzymes in the liver and intestines, which can lead to increased levels of atorvastatin in the blood. This raises the risk of adverse effects, particularly muscle toxicity.
C. "Report any muscle pain, weakness, or tenderness to your healthcare provider immediately.": These symptoms may indicate myopathy or rhabdomyolysis, a rare but serious adverse effect of statins. Early reporting allows for prompt evaluation and potential discontinuation of the drug to prevent complications.
D. "You can use an NSAID prior to taking your atorvastatin to prevent flushing.": Flushing is not a common side effect of atorvastatin; this teaching applies to niacin, not statins. Using NSAIDs prophylactically for atorvastatin is unnecessary and not clinically indicated.

Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A"},"C":{"answers":"B"},"D":{"answers":"B"},"E":{"answers":"B"},"F":{"answers":"A"}}
Explanation
- Hypertension: Seen in anticholinergic toxicity due to decreased parasympathetic tone and possible unopposed sympathetic stimulation. The body's inability to relax vascular tone may contribute to elevated blood pressure.
- Urinary Retention: A classic feature of anticholinergic toxicity. Inhibition of muscarinic receptors leads to impaired detrusor muscle contraction, making urination difficult or impossible.
- Hyperthermia: Results from inhibited sweating (anhidrosis), which is a hallmark of anticholinergic toxicity. Without the ability to cool through evaporation, body temperature rises dangerously.
- Diaphoresis: Excessive sweating is mediated by muscarinic receptor activation in cholinergic toxicity. It's often part of the SLUDGE symptoms seen in organophosphate poisoning or cholinesterase inhibitor overdose.
- Bronchoconstriction: Caused by overstimulation of muscarinic receptors in the airways, leading to narrowed bronchi and increased respiratory secretions — a dangerous feature of cholinergic excess.
- Salivation: Prominent in cholinergic toxicity due to unopposed parasympathetic activation. It may occur along with lacrimation, bradycardia, and other signs of excessive cholinergic stimulation.
Correct Answer is ["36"]
Explanation
Given quantity = 4.5 cups
Desired unit = ounces (fluid ounces, as cups are a measure of volume)
Convert from cups to fluid ounces
1 cup = 8 fluid ounces
4.5 cups × 8 fluid ounces/cup
= 36 fluid ounces
