A nurse is providing teaching to a client who has erectile dysfunction and has a new prescription for tadalafil. Which of the following client statements indicates an understanding of the teaching?

A.

I should crush this medication if I have difficulty swallowing.

B.

This medication can decrease my blood pressure.

C.

I can take this medication up to twice a day.

D.

The effects of this medication will not last more than 4 hours.

Answer and Explanation

The Correct Answer is B

Choice A rationale

 

Crushing tadalafil is not recommended as it can alter the medication’s effectiveness and absorption. Tadalafil should be taken whole to ensure proper dosage and efficacy.

 

Choice B rationale

 

Tadalafil can decrease blood pressure by relaxing blood vessels, which allows for increased blood flow. This is a known effect of phosphodiesterase type 5 (PDE5) inhibitors like tadalafil.

 

Choice C rationale

 

Tadalafil should not be taken more than once a day. Taking it twice a day can increase the risk of side effects and is not recommended.

 

Choice D rationale

 

The effects of tadalafil can last up to 36 hours, not just 4 hours. This prolonged duration is one of the reasons it is preferred by some patients.

Correct Answer is A

Explanation

Choice A rationale

A neutrophil count of 650/mm³ is significantly lower than the normal range (2,500 to 8,000/mm³) and indicates neutropenia, which is a known adverse effect of zidovudine. Neutropenia increases the risk of infections and requires close monitoring and potential dose adjustment or discontinuation of the medication.

Choice B rationale

A platelet count of 450,000/mm³ is slightly above the normal range (150,000 to 400,000/mm³) but is not typically associated with zidovudine toxicity. Zidovudine is more commonly associated with bone marrow suppression leading to anemia and neutropenia rather than thrombocytosis.

Choice C rationale

An Hgb level of 17 g/dL is above the normal range for females (12 to 16 g/dL) but is not a common adverse effect of zidovudine. Zidovudine is more likely to cause anemia, leading to lower hemoglobin levels rather than elevated levels.

Choice D rationale

A creatinine level of 1.5 mg/dL is within the upper limit of the normal range (0.5 to 1 mg/dL) and is not a typical adverse effect of zidovudine. Zidovudine primarily affects the bone marrow and does not have a significant impact on renal function.

Correct Answer is C

Explanation

Choice A rationale

Expecting to have drowsiness while taking this medication is a common side effect of many seizure medications. However, it is not an indication of understanding the teaching about seizure medication management.

Choice B rationale

Taking an extra dose of the medication if a dose is missed is incorrect. Patients should not take an extra dose if they miss one. They should follow their healthcare provider’s instructions on what to do if a dose is missed.

Choice C rationale

Having blood checked to monitor the medication level indicates an understanding of the teaching. Monitoring blood levels of seizure medications is important to ensure therapeutic levels and avoid toxicity.

Choice D rationale

Taking the medication with an antacid to prevent indigestion is incorrect. Antacids can interfere with the absorption of some seizure medications.
