1. The client is on a beta blocker for hypertension. What should the nurse monitor for?

• A. Bradycardia
• B. Tachycardia
• C. Hypertension
• D. Respiratory distress

Correct answer: A

Rationale: Corrected Rationale: When a client is on a beta blocker for hypertension, the nurse should monitor for bradycardia. Beta blockers are known to decrease heart rate, which can lead to bradycardia. Tachycardia (choice B) is unlikely as beta blockers have the opposite effect. Hypertension (choice C) is the condition being treated, not a side effect of beta blockers. Respiratory distress (choice D) is not a common effect of beta blockers and is not typically monitored in clients taking beta blockers.

2. During which process does coronary artery blood flow to the myocardium occur during diastole, when coronary vascular resistance is reduced?

• A. Coronary perfusion pressure
• B. Coronary vascular resistance
• C. Diastolic filling
• D. Ventricular ejection

Correct answer: A

Rationale: The correct answer is A: Coronary perfusion pressure. Coronary perfusion pressure refers to the process of coronary artery blood flow to the myocardium during diastole when coronary vascular resistance is reduced. This process ensures that the myocardium receives sufficient oxygen and nutrients for proper functioning. Choice B, Coronary vascular resistance, is the opposite of what is described in the question. During coronary perfusion, resistance is reduced to enhance blood flow. Choices C and D, Diastolic filling and Ventricular ejection, do not directly relate to the process of coronary artery blood flow during diastole.

3. After the AV node, the electrical impulse is then transmitted into the _________, and into the _________.

• A. Purkinje fibers, ventricles
• B. Atria, ventricles
• C. Bundle of His, Purkinje fibers
• D. Ventricles, Purkinje fibers

Correct answer: C

Rationale: The correct answer is C. After the AV node, the electrical impulse is transmitted to the Bundle of His and then to the Purkinje fibers. This sequence is crucial for the coordinated contraction of the ventricles. Choice A (Purkinje fibers, ventricles) is incorrect because the Purkinje fibers come after the Bundle of His in the sequence of electrical conduction. Choice B (Atria, ventricles) is incorrect because the impulse does not go back to the atria after passing through the AV node. Choice D (Ventricles, Purkinje fibers) is incorrect because the impulse first reaches the Bundle of His before spreading to the Purkinje fibers.

4. What is a type of medication that helps to prevent blood clots by thinning the blood?

• A. Anticoagulant
• B. Beta-blocker
• C. ACE inhibitor
• D. Calcium channel blocker

Correct answer: A

Rationale: Anticoagulants are medications specifically designed to prevent blood clots by thinning the blood. They work by interfering with the body's blood clotting process. Beta-blockers, ACE inhibitors, and calcium channel blockers are medications used for different purposes such as managing blood pressure, heart conditions, and regulating heart rhythm, respectively. However, they do not have the primary function of preventing blood clots like anticoagulants.

5. What is an acute respiratory infection that inflames the alveoli in one or both lungs, causing them to fill with fluid or pus?

• A. Pneumonia
• B. Bronchitis
• C. Tuberculosis
• D. Asthma

Correct answer: A

Rationale: Pneumonia is the correct answer because it is an acute respiratory infection that inflames the alveoli in one or both lungs, leading to the accumulation of fluid or pus. This condition presents with symptoms like cough, fever, and difficulty breathing. Bronchitis is the inflammation of the bronchial tubes, not the alveoli. Tuberculosis is a bacterial infection that primarily affects the lungs but does not always result in alveolar inflammation. Asthma is a chronic respiratory condition characterized by airway inflammation and narrowing, not alveolar inflammation.
