Which antihypertensive medication is not recommended for patients with chronic obstructive pulmonary disease (COPD) and asthma?

The correct answer is Choice D.

Choice A rationale: Allergies to shellfish may indicate iodine allergy, relevant for procedures using iodine-based contrast, like PCI. The client’s shellfish allergy must be reported to the PHCP as a precautionary measure to prevent any allergic reaction.

Choice B rationale: Warm sensations during PCI are a common side effect of the contrast dye used in the procedure. This statement does not indicate an immediate concern requiring PHCP notification as it is a standard patient experience.

Choice C rationale: Anxiety in closed spaces, known as claustrophobia, may affect the client's comfort during PCI but can be managed with sedatives. The PHCP should be aware but it’s not as urgent as taking contraindicated medications.

Choice D rationale: Metformin can lead to lactic acidosis, especially when iodine contrast dye is used during PCI. This condition is serious and may result in adverse interactions. The PHCP must be notified immediately.

Choice A rationale
The diaphragm is not typically the location of a coarctation of the aorta. The diaphragm is a muscle that helps with breathing and separates the chest cavity from the abdominal cavity.
Choice B rationale
The bifurcation into the common iliac arteries is not typically the location of a coarctation of the aorta. The common iliac arteries are located in the lower part of the aorta and supply blood to the pelvis and legs.
Choice C rationale
The aortic valve is not typically the location of a coarctation of the aorta. The aortic valve is located between the left ventricle of the heart and the aorta.
Choice D rationale
The ductus arteriosus is the correct answer. Coarctation of the aorta often occurs near the ductus arteriosus, a blood vessel that connects the left pulmonary artery to the aorta.
