The nurse is providing instruction to a patient who was recently prescribed an ACE inhibitor for hypertension. Which is an adverse effect of this medication?
Constipation
Hypokalemia
Chronic cough
Nervousness
The Correct Answer is C
Choice A reason: This is not an adverse effect of ACE inhibitors. Constipation is a common side effect of opioid medications, which slow down the intestinal motility and cause hard stools.
Choice B reason: This is not an adverse effect of ACE inhibitors. Hypokalemia is a low level of potassium in the blood, which can be caused by diuretic medications, such as furosemide or hydrochlorothiazide, which increase the urine output and potassium excretion.
Choice C reason: This is an adverse effect of ACE inhibitors. Chronic cough is a dry, persistent cough that occurs in some patients taking ACE inhibitors, due to the accumulation of bradykinin, a substance that causes inflammation and irritation in the respiratory tract.
Choice D reason: This is not an adverse effect of ACE inhibitors. Nervousness is a common side effect of stimulant medications, such as caffeine or amphetamine, which increase the activity of the central nervous system and cause anxiety, agitation, and insomnia.

Correct Answer is B
Explanation
Choice A reason: Lipid-laden mast cells are not foam cells. Mast cells are immune cells that release histamine and other inflammatory mediators. They do not accumulate lipids or have a soap-like texture.
Choice B reason: Macrophages that engulf low-density lipoproteins (LDLs) are foam cells. They are part of the atherosclerotic process that leads to plaque formation in the blood vessels. They are called foam cells because they have a foamy appearance under the microscope.
Choice C reason: Injured neutrophil clots are not foam cells. Neutrophils are immune cells that fight infection and form pus. They do not engulf LDLs or contribute to atherosclerosis.
Choice D reason: Deposited adipose cells are not foam cells. Adipose cells are fat cells that store energy and secrete hormones. They do not phagocytose LDLs or form plaques in the blood vessels.
Correct Answer is D
Explanation
Choice A reason: Hyperplasia and deformation of bronchial cartilage are not the causes of airway obstruction in COPD type B. Bronchial cartilage is the rigid structure that supports the bronchi, the large airways that branch from the trachea. Hyperplasia is an increase in the number of cells, and deformation is a change in the shape or structure of the cells. These processes can affect the bronchial cartilage, but they do not directly obstruct the airway.
Choice B reason: Loss of alveolar elastin is not the cause of airway obstruction in COPD type B. Alveolar elastin is the elastic fiber that allows the alveoli, the tiny air sacs at the end of the bronchioles, to expand and recoil during breathing. Loss of alveolar elastin is a characteristic of COPD type A (emphysema), which causes the alveoli to lose their shape and collapse. This reduces the surface area for gas exchange, but it does not obstruct the airway.
Choice C reason: Pulmonary edema is not the cause of airway obstruction in COPD type B. Pulmonary edema is the accumulation of fluid in the lungs, usually due to heart failure or lung injury. It causes shortness of breath, coughing, and crackles in the lungs. It can impair gas exchange and oxygenation, but it does not obstruct the airway.
Choice D reason: Thick mucus, fibrosis, and smooth muscle hypertrophy are the causes of airway obstruction in COPD type B. Thick mucus is the result of chronic inflammation and infection of the bronchi, which stimulates the mucus glands to produce more and thicker mucus. Fibrosis is the formation of scar tissue in the bronchial walls, which narrows the airway and reduces its elasticity. Smooth muscle hypertrophy is the enlargement of the smooth muscle cells that surround the bronchi, which increases the airway resistance and causes bronchospasm. These processes combine to obstruct the airway and cause chronic cough, wheezing, and dyspnea.
