What short term pharmacological approach is used after a client has a prosthetic heart valve replacement for 1 to 2 months postoperatively?
- A. Anticoagulant therapy
- B. Antibiotic therapy
- C. Ace Inhibitor therapy
- D. Beta Blocker therapy
Correct Answer: A
Rationale: Anticoagulant therapy prevents clot formation around the prosthetic valve, reducing the risk of complications.

What is a device that delivers a fine spray of medication into the airways?
- A. Nebulizer
- B. Inhaler
- C. Oxygen concentrator
- D. Peak flow meter
Correct Answer: A
Rationale: The correct answer is A: Nebulizer. A nebulizer is a device that delivers medication in the form of a fine spray into the airways, making it easier for the patient to inhale the medication and reach the lungs. It is commonly used for treating respiratory conditions such as asthma and COPD. Inhalers (B) deliver medication in a different format, through a measured dose of medication in aerosol form. Oxygen concentrators (C) provide supplemental oxygen and do not deliver medication. Peak flow meters (D) are used to measure the peak expiratory flow rate and are not used to deliver medication.
What is a chronic condition where the blood pressure in the arteries is persistently elevated, increasing the risk of heart disease and stroke?
- A. Hypertension
- B. Hypotension
- C. Hyperlipidemia
- D. Hyperglycemia
Correct Answer: A
Rationale: The correct answer is A: Hypertension. Hypertension is characterized by persistently elevated blood pressure, which increases the risk of heart disease and stroke. This condition is commonly referred to as high blood pressure. Hypotension (B) is the opposite, indicating low blood pressure. Hyperlipidemia (C) is high levels of fats in the blood, not directly related to blood pressure. Hyperglycemia (D) is high blood sugar levels, also not directly related to blood pressure. Therefore, based on the definition and associated health risks, A is the correct choice.
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:
- A. a referral for counseling and possible medication.
- B. a trial of herbal remedies.
- C. alternative therapies, including yoga and massage.
- D. comprehensive information about the patient's cardiac status to help reduce their anxiety.
Correct Answer: A
Rationale: Referral for counseling and medication is appropriate for managing depression in this context.
What test measures the electrical activity of the heart over a 24- or 48-hour period?
- A. Holter monitor
- B. Electrocardiogram
- C. Stress test
- D. Chest X-ray
Correct Answer: A
Rationale: The correct answer is A: Holter monitor. This device records the electrical activity of the heart over an extended period, typically 24-48 hours, providing a more comprehensive assessment compared to a standard ECG (choice B). A stress test (choice C) evaluates the heart's response to physical exertion, not prolonged monitoring. A chest X-ray (choice D) is used to visualize the heart and lungs, but does not measure electrical activity. Therefore, the Holter monitor is the most appropriate test for continuous monitoring of heart activity over an extended period.
Which of the following is a chronic respiratory disease characterized by the irreversible obstruction of airflow?
- A. Chronic obstructive pulmonary disease (COPD)
- B. Asthma
- C. Pulmonary edema
- D. Bronchiectasis
Correct Answer: A
Rationale: The correct answer is A: Chronic obstructive pulmonary disease (COPD). COPD is a chronic respiratory disease characterized by irreversible airflow obstruction due to conditions such as emphysema and chronic bronchitis. This is because COPD causes damage to the airways and alveoli, leading to decreased airflow. Asthma (B) is a chronic inflammatory disease with reversible airflow obstruction. Pulmonary edema (C) is caused by fluid accumulation in the lungs, leading to difficulty in breathing but is not characterized by irreversible airflow obstruction. Bronchiectasis (D) involves the widening and scarring of the airways, leading to recurrent infections, but it is not specifically characterized by irreversible airflow obstruction.
