A nurse in a provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?
Metronidazole
Phenytoin
Prednisone
Isosorbide
The Correct Answer is D
Rationale:
A. Metronidazole: Metronidazole is an antibiotic and does not have significant interactions with sildenafil.
B. Phenytoin: Phenytoin is an anticonvulsant medication and does not have significant interactions with sildenafil.
C. Prednisone: Prednisone is a corticosteroid and does not have significant interactions with sildenafil.
D. Isosorbide: Isosorbide is a nitrate medication used to treat angin
A. Combining sildenafil with nitrate medications can lead to severe hypotension and is contraindicated. Sildenafil potentiates the vasodilatory effects of nitrates, which can result in a dangerous drop in blood pressure.

Correct Answer is ["5.3"]
Explanation
To calculate the dosage of acetaminophen for the child, first convert the child's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds.
The child weighs 28 lb, which is approximately 12.7 kg (28 / 2.2 = 12.7).
The prescribed dose is 10 mg/kg, so the child's dose is 127 mg (10 mg/kg 12.7 kg).
Now, using the concentration of the available medication, which is 120 mg/5 mL, you can calculate the volume of medication needed.
For 120 mg of acetaminophen, 5 mL of liquid is required, so for 127 mg, it would be 5 mL (127 mg / 120 mg) = 5.29 mL.
Therefore, the nurse should administer 5.3 mL, rounding to the nearest tenth as instructed.
