A staff member asks a nurse to describe foam cells. The nurse's best response is that foam cells are
lipid-laden mast cells that have a soap-like texture.
macrophages that engulf low-density lipoproteins (LDLs).
injured neutrophil clots.
deposited adipose cells.
The Correct Answer is B
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 C
Explanation
Choice A reason: This is not the best response by the nurse. Stopping the medication abruptly can cause rebound hypertension and other complications. The patient should not stop taking the medication without consulting their health care provider.
Choice B reason: This is not the best response by the nurse. Cutting the pill in half and taking a reduced dosage can affect the efficacy and safety of the medication. The patient should not change the dosage of the medication without consulting their health care provider.
Choice C reason: This is the best response by the nurse. Dizziness is a common side effect of ACE inhibitors, especially when the patient changes position or stands up quickly. This is due to the orthostatic hypotension (a drop in blood pressure when standing up) caused by the vasodilation effect of the medication. However, this side effect is usually mild and transient, and can be prevented by rising slowly from a sitting or lying position, drinking plenty of fluids, and avoiding alcohol.
Choice D reason: This is not the best response by the nurse. Scheduling the patient to visit the health care provider today is not necessary, unless the dizziness is severe, persistent, or accompanied by other symptoms, such as chest pain, fainting, or palpitations. The patient should be advised to monitor their blood pressure and report any significant changes or concerns to their health care provider.
Correct Answer is D
Explanation
Choice A reason: Decreased cardiac output would result in a decrease in blood pressure, not an increase. Cardiac output is the amount of blood pumped by the heart per minute.
Choice B reason: Decreased vascular resistance would also result in a decrease in blood pressure, not an increase. Vascular resistance is the force that opposes the blood flow in the blood vessels.
Choice C reason: Hypovolemia would also result in a decrease in blood pressure, not an increase. Hypovolemia is the condition of having low blood volume due to fluid loss or dehydration.
Choice D reason: Vasoconstriction would result in an increase in blood pressure. Vasoconstriction is the narrowing of the blood vessels, which increases the vascular resistance and the blood pressure.
