100 Questions on the Cardiovascular System Questions
Question 1 of 5
Which of the following adverse reactions should the nurse assess in a 70-year-old adult who is receiving a continuous infusion of lidocaine?
Correct Answer: C
Rationale: Lidocaine (C) can cause confusion, especially in older adults, as a CNS side effect. Hypertension (A), osteoarthritis (B), and visual changes (D) are unrelated.
Question 2 of 5
The following statements are made about the variety of thermoregulatory mechanisms in the body. A. Human voluntary activity is decreased in cold. B. There is a cutaneous vasodilation by heat. C. There is an increased secretion of epinephrine and nor-epinephrine in cold. D. There is a decreased heat production in cold. Choose the combination of all correct statements about thermoregulatory mechanisms:
Correct Answer: B
Rationale: A is true (cold reduces activity to conserve heat), B is true (heat causes cutaneous vasodilation to dissipate heat), C is true (cold increases epinephrine/norepinephrine for heat production), but D is false (heat production increases in cold). B (B and C) is the best fit for correct statements.
Question 3 of 5
During a routine physical examination, a client reports recent occipital headaches, blurred vision, fatigue, and increasing oedema. The nurse reports these findings as indicative of
Correct Answer: A
Rationale: Occipital headaches, blurred vision, fatigue, and edema suggest hypertension, which increases vascular pressure and fluid retention. Hypovolemia causes low volume, endocarditis involves infection, and tachycardia is arrhythmia-related.
Question 4 of 5
A patient who is in the 10th week of outpatient cardiac rehabilitation continues to exhibit symptoms of depression. When developing a discharge plan, the cardiac-vascular nurse includes:
Correct Answer: A
Rationale: Persistent depression requires professional intervention (counseling and possibly antidepressants), as it’s a serious condition post-cardiac event. Herbal remedies (B) lack evidence here, C is adjunctive, and D may not address the root psychological issue.
Question 5 of 5
A patient who underwent coronary artery bypass surgery demonstrates effective understanding of discharge teaching by:
Correct Answer: B
Rationale: Clarifying cardiac rehab timing shows understanding of recovery steps post-CABG. A (smoking), C (hot tubs risk infection), and D (driving too soon) indicate poor grasp of restrictions and rehab needs.
