The nurse is planning discharge education for a client with a new prescription for montelukast. Which adverse effect should the nurse instruct the client to report to the healthcare provider?

A. Stop taking theophylline if you begin smoking: While smoking significantly increases the metabolism of theophylline (requiring a dose increase to stay effective), the patient should never just stop the medication. Instead, they must notify their provider so the dosage can be adjusted.

B. Theophylline should be taken every day: Theophylline is used for maintenance therapy in conditions like asthma or COPD. Consistent daily dosing helps maintain therapeutic serum levels and prevent exacerbations.

C. Headaches may occur when taking theophylline: Headache is a common side effect due to central nervous system stimulation. Clients should be informed so they can recognize mild, expected reactions versus more serious adverse effects.

D. Report palpitations to your healthcare provider: Theophylline can cause cardiac stimulation, including tachycardia or palpitations. Reporting these symptoms promptly helps prevent serious arrhythmias and allows for dosage adjustment if needed.

E. If you forget your dose, take two the next day: Doubling the dose to make up for a missed one increases the risk of toxicity, including seizures or severe cardiac effects. Clients should take only the next scheduled dose as prescribed.

A. The client reports a recent onset of muscle pain: Muscle pain or weakness (myalgia) is a known adverse effect of atorvastatin and can indicate a serious complication such as rhabdomyolysis. This finding requires immediate assessment and possible adjustment of the medication regimen.

B. The client's high-density lipoprotein (HDL) increased: An increase in HDL is a desired effect of atorvastatin therapy. This finding is beneficial and indicates that the medication is helping improve lipid profile and cardiovascular risk.

C. The client started taking oral contraceptive pills: While statins can slightly increase the hormone levels of birth control pills, this is a known interaction but not an immediate clinical "finding" that would be as concerning as potential muscle breakdown.

D. The client's blood pressure is 116/78 while sitting: This blood pressure reading is within normal limits for an adult. It does not indicate a concerning clinical finding in the context of atorvastatin therapy.
