Cardiovascular Physiology Practice Questions Questions
Question 1 of 5
The client is diabetic and is given a non-cardio-selective beta blocker. What might happen to the blood sugars?
Correct Answer: B
Rationale: The correct answer is B because non-cardio-selective beta blockers can inhibit glycogenolysis in the liver, leading to decreased production of glucose from glycogen. This can result in a drop in blood sugar levels. Choice A is incorrect because beta blockers do not increase breakdown of glycogen. Choice C is incorrect as beta blockers do impact blood sugar levels. Choice D is incorrect because beta blockers do not increase cellular uptake of glucose.
Question 2 of 5
Which food supplement should the nurse be concerned about in a client taking an ACE inhibitor?
Correct Answer: B
Rationale: The correct answer is B: Potassium chloride. ACE inhibitors can cause potassium levels to increase, leading to hyperkalemia. Potassium chloride is a potassium supplement that can further elevate potassium levels, potentially causing adverse effects. Sodium chloride (A) does not directly impact potassium levels. Cayenne pepper (C) and ground black pepper (D) are not known to interact significantly with ACE inhibitors. Hence, the nurse should be concerned about the client taking potassium chloride while on an ACE inhibitor to avoid complications related to hyperkalemia.
Question 3 of 5
The client is given low molecular weight heparin at home. In teaching the client, the nurse explains that the drug works by doing what?
Correct Answer: B
Rationale: The correct answer is B: Inactivates clotting factor Xa. Low molecular weight heparin works by binding to antithrombin III and inactivating factor Xa, which is essential in the coagulation cascade. This inhibits the formation of new clots. Choice A is incorrect because heparin does not directly act as an anti-platelet agent. Choice C is incorrect as heparin does not directly inactivate thrombin. Choice D is incorrect as heparin does not directly increase fibrinolysis.
Question 4 of 5
The client is taking a medication that is an ADP receptor blocker for the prevention of ischemic stroke. What might this medication be?
Correct Answer: D
Rationale: The correct answer is D: Plavix. Plavix is an ADP receptor blocker that inhibits platelet aggregation, reducing the risk of blood clot formation and preventing ischemic stroke. Aspirin (A) is an antiplatelet agent but works through a different mechanism. Heparin (B) is an anticoagulant that works by inhibiting thrombin and factor Xa, not through ADP receptor blocking. Warfarin (C) is a vitamin K antagonist that interferes with the synthesis of clotting factors, also not through ADP receptor blocking.
Question 5 of 5
The client is taking niacin for cholesterol reduction. What common adverse reaction should the nurse warn the client about?
Correct Answer: D
Rationale: The correct answer is D: Facial flushing. Niacin commonly causes facial flushing as an adverse reaction due to prostaglandin release. This is a well-known side effect and is usually harmless. Dizziness (A), urinary retention (B), and constipation (C) are not common adverse reactions associated with niacin use. It is important for the nurse to educate the client about the potential for facial flushing with niacin therapy to manage expectations and ensure compliance.
