A patient is taking acetaminophen (Tylenol) 325 mg, 2 tablets PO every 6 hours. How many grams is the patient receiving in 24 hours?

(Number Only, do not type in gram or g with your answer)

The correct answer is choice A: "Urethral opening along ventral surface of penis."

Choice A rationale:

The statement "Urethral opening along ventral surface of penis" is correct. Hypospadias is a congenital condition where the opening of the urethra is located on the underside of the penis rather than at the tip. This anomaly requires surgical correction.

Choice B rationale:

The statement "Urethral opening along dorsal surface of penis" is incorrect. This statement describes an anatomically incorrect condition. The opening of the urethra is not supposed to be along the dorsal surface of the penis.

Choice C rationale:

The statement "Absence of a urethral opening" is incorrect. This statement describes a more severe condition called "urethral agenesis" where the urethral opening is completely absent. Hypospadias is different and involves a misplaced urethral opening.

Choice D rationale:

The statement "Penis shorter than usual for age" is not related to hypospadias. Hypospadias primarily involves the location of the urethral opening and is unrelated to the length of the penis.

The correct answer is choice B. Cardiac valve damage.

Choice A rationale:

Pulmonary hypertension is not a common complication of rheumatic fever. Rheumatic fever primarily affects the heart, joints, skin, and brain, and pulmonary hypertension is not a typical manifestation of this condition.

Choice B rationale:

Cardiac valve damage is a common and serious complication of rheumatic fever. Rheumatic fever is caused by an autoimmune reaction to untreated streptococcal infections, particularly Streptococcus pyogenes. The immune response targets not only the streptococcal bacteria but also the body's own tissues, especially heart valves. This can lead to inflammation of the heart valves, a condition known as rheumatic heart disease. Over time, repeated bouts of rheumatic fever can result in significant damage to the heart valves, leading to valve insufficiency or stenosis. This can ultimately cause heart failure and other cardiovascular complications.

Choice C rationale:

Seizures are not a common complication of rheumatic fever. Rheumatic fever primarily affects the heart and other body systems, but it does not typically lead to seizures.

Choice D rationale:

Cardiac arrhythmias are possible complications of rheumatic fever, but they are not as common or significant as cardiac valve damage. The inflammation and scarring caused by rheumatic fever can disrupt the electrical pathways of the heart, potentially leading to arrhythmias. However, the more prevalent and severe consequence of rheumatic fever is the damage to the heart valves.
