I should not have any coffee 3 hours after the exam.

I should not exercise 3 hours after the exam.

I should not have beta blockers 3 hours before the exam.

I should not smoke 3 hours before the exam.

Answer and Explanation

The Correct Answer is C

A. “I should not have any coffee 3 hours after the exam.” This statement is not accurate. The restriction related to coffee is usually before the test, not after.

B. “I should not exercise 3 hours after the exam.” This statement is incorrect. The restriction on exercise typically applies before the test, not after.

C. “I should not have beta blockers 3 hours before the exam.” Correct! Beta blockers can affect heart rate and blood pressure, so avoiding them before the test is essential.

D. “I should not smoke 3 hours before the exam.” While it’s generally advisable to avoid smoking before the test, this statement does not specifically address the cardiac stress test.

Correct Answer is B

Explanation

Rationale:

A. Partial thromboplastin time (PTT) is used to monitor the effectiveness of heparin therapy, not warfarin.

B. Prothrombin time (PT) and international normalized ratio (INR) are used to monitor the therapeutic level of warfarin. INR is the preferred method as it standardizes the PT results across different laboratories.

C. D-dimer level is a marker of fibrin degradation and is used to assess for the presence of blood clots, not to monitor warfarin therapy.

D. Vitamin K level is not used to monitor warfarin therapy. However, administering vitamin K can reverse the effects of warfarin in cases of overdose or hemorrhage.

A. The client will include trans fat foods in the diet. B. The client will switch to chewing tobacco only. C. The client will walk for 30 minutes, 5 days a week. D. The client will lower their sodium intake to 5200 g/day.

Correct Answer is C

Explanation

Rationale:

A. Including trans fat foods in the diet is not a health-promoting behavior and would not prevent cardiovascular disease. In fact, trans fats are associated with an increased risk of cardiovascular disease.

B. Switching to chewing tobacco only is not a health-promoting behavior. Tobacco use, in any form, is harmful to cardiovascular health and increases the risk of cardiovascular disease.

C. Regular physical activity, such as walking for 30 minutes, 5 days a week, is a health- promoting behavior that can help prevent cardiovascular disease by improving cardiovascular fitness, lowering blood pressure, and reducing the risk of obesity and diabetes.

D. Lowering sodium intake to 5200 g/day is not feasible or appropriate. In fact, such a high sodium intake would be harmful to cardiovascular health. The recommended daily intake of sodium for adults is much lower, typically around 2300 mg per day or less, depending on individual health conditions.
