The nurse reviews a primary health care provider’s prescriptions and notes that a topical nitrate is prescribed. The nurse notes that acetaminophen is prescribed to be administered before the nitrate.
The nurse implements the prescription with which understanding about why acetaminophen is prescribed?

Choice A rationale

A mesh-like device within the catheter that springs open is characteristic of a stent, not a balloon-tipped catheter used in PTCA. Stents are often used in conjunction with angioplasty to keep the artery open after the balloon has compressed the plaque.

Choice B rationale

While catheters can be used to take pressure measurements, this is not the primary function of the balloon-tipped catheter in PTCA. The main purpose of the balloon-tipped catheter is to compress the plaque against the artery wall to improve blood flow.

Choice C rationale

The balloon-tipped catheter in PTCA is used to compress the plaque against the coronary blood vessel wall. This process, known as balloon angioplasty, helps to widen the artery and improve blood flow to the heart.

Choice D rationale

Cutting away plaque with an embedded blade is a description of atherectomy, not PTCA. Atherectomy involves a different type of catheter designed to remove plaque from the artery wall.

Choice A rationale

Fat neck veins are not a typical finding in a client with frequent vomiting and diarrhea. Dehydration, which is common in such cases, usually leads to flat neck veins due to reduced intravascular volume.

Choice B rationale

Hypotension is a common finding in clients with frequent vomiting and diarrhea due to fluid loss and dehydration. The loss of fluids leads to a decrease in blood volume, resulting in low blood pressure.

Choice C rationale

Poor skin turgor is a classic sign of dehydration, which is expected in clients with frequent vomiting and diarrhea. Dehydration causes the skin to lose its elasticity, leading to poor skin turgor.

Choice D rationale

Bradycardia is not typically associated with dehydration. In fact, dehydration often leads to tachycardia (increased heart rate) as the body tries to compensate for the reduced blood volume.

Choice E rationale

Pale yellow urine is not a typical finding in dehydration. Dehydration usually leads to concentrated urine, which is darker in color. Pale yellow urine indicates adequate hydration.
