When administering an ACE inhibitor to a client with heart failure, what is the expected outcome of this medication?
- A. Decreased blood pressure
- B. Increased heart rate
- C. Increased cardiac output
- D. Decreased heart rate
Correct Answer: C
Rationale: The correct answer is C: Increased cardiac output. ACE inhibitors work by dilating blood vessels and reducing the workload on the heart. This leads to improved cardiac output, as the heart can pump more efficiently. Decreased blood pressure (choice A) is a common side effect due to vasodilation. Increased heart rate (choice B) and decreased heart rate (choice D) are not expected outcomes of ACE inhibitor use. Therefore, the most appropriate and expected outcome of administering an ACE inhibitor in heart failure is an increase in cardiac output, making choice C the correct answer.

What is a condition where the airways become swollen and produce extra mucus, making it difficult to breathe, often associated with COPD?
- A. Chronic bronchitis
- B. Pneumonia
- C. Emphysema
- D. Tuberculosis
Correct Answer: A
Rationale: Rationale:
1. Chronic bronchitis is characterized by inflammation of the airways leading to excess mucus production.
2. It is a common symptom of COPD, obstructing airflow and causing breathing difficulties.
3. Pneumonia, emphysema, and tuberculosis do not primarily involve airway inflammation and mucus production as seen in chronic bronchitis.
What is a condition where the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients?
- A. Stroke
- B. Heart attack
- C. Pulmonary embolism
- D. Pneumonia
Correct Answer: A
Rationale: The correct answer is A: Stroke. A stroke occurs when the blood supply to part of the brain is interrupted or reduced, leading to brain tissue not receiving enough oxygen and nutrients. This can result in permanent brain damage or even death.
Choice B: Heart attack, involves a blockage in the blood vessels supplying the heart muscle, not the brain.
Choice C: Pulmonary embolism, is a blockage in the arteries of the lungs, not the brain.
Choice D: Pneumonia, is an infection in the lungs and does not directly involve the brain's blood supply.
In summary, a stroke specifically affects the brain's blood supply and can lead to serious consequences, unlike the other conditions mentioned.
While completing a nursing admission history, you obtain this information about the patient's cardiovascular risk factors: patient's mother and two siblings have had myocardial infarctions. Patient smokes and has a 20 pack/year history of cigarette use. Her work as a mail carrier involves a lot of walking. She takes metoprolol (Lopressor) for hypertension and her blood pressure has been in the range of 130/60 to 140/85. Which interventions will be most important to include in the discharge plan? (Choose all that apply.)
- A. Refer to community programs that assist in smoking cessation.
- B. Teach about the impact of family history on cardiovascular risk.
- C. Educate about the need for a change in antihypertensive therapy.
- D. Assist in reducing the stress associated with her cardiovascular risk.
Correct Answer: A
Rationale: Smoking cessation is crucial given her history and risk factors.
Which of the following are the reasons a nurse discourages the consumption of alcohol for a client with mitral valve prolapse?
- A. Tachycardia
- B. Cinchonism
- C. Hypertension
- D. Cardiac stimulation
Correct Answer: D
Rationale: Alcohol can stimulate the heart, exacerbating symptoms in clients with mitral valve prolapse.
The nurse is caring for a client on amiodarone. What adverse effect is the nurse most concerned about?
- A. Pulmonary toxicity
- B. Liver toxicity
- C. Thyroid dysfunction
- D. Renal dysfunction
Correct Answer: A
Rationale: The correct answer is A: Pulmonary toxicity. Amiodarone is known to cause potentially life-threatening pulmonary toxicity, including interstitial pneumonitis and pulmonary fibrosis. The nurse must closely monitor the client for signs such as cough, dyspnea, and chest pain. Liver toxicity (B), thyroid dysfunction (C), and renal dysfunction (D) are also possible adverse effects of amiodarone, but pulmonary toxicity is the most concerning due to its severe and rapid progression. Monitoring and early detection are crucial to prevent serious complications.
