1. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

2. The nurse is assessing a client with a suspected pulmonary embolism (PE). Which symptom is most indicative of this condition?

• A. Bilateral leg swelling.
• B. Sudden onset of chest pain.
• C. Gradual onset of dyspnea.
• D. Decreased breath sounds on auscultation.

Correct answer: C

Rationale: The correct answer is C: 'Gradual onset of dyspnea.' While pulmonary embolism can present with various symptoms, the most common include sudden onset of dyspnea, chest pain (often pleuritic in nature), tachypnea, and tachycardia. Bilateral leg swelling is more commonly associated with conditions like deep vein thrombosis, not pulmonary embolism. Decreased breath sounds on auscultation may be seen in conditions like pneumothorax, not typically in pulmonary embolism. Therefore, the gradual onset of dyspnea is the most indicative symptom of pulmonary embolism in this scenario.

3. A client comes to the antepartal clinic and tells the nurse that she is 6 weeks pregnant. Which sign is she most likely to report?

• A. Decreased sexual libido
• B. Amenorrhea
• C. Quickening
• D. Nocturia

Correct answer: B

Rationale: Amenorrhea is the absence of menstrual periods and is a common early sign of pregnancy, typically reported by a client who is 6 weeks pregnant. Decreased sexual libido (Choice A) may or may not be experienced in early pregnancy, but it is not as specific as amenorrhea. Quickening (Choice C) refers to fetal movements felt by the mother, which usually occurs around 18-20 weeks of pregnancy, not at 6 weeks. Nocturia (Choice D) is waking up at night to urinate and is not typically associated with early pregnancy.

4. A client with pneumonia is experiencing difficulty expectorating thick secretions. What intervention should the nurse implement to assist the client?

• A. Administer antibiotics as prescribed
• B. Perform chest physiotherapy
• C. Encourage increased fluid intake
• D. Provide humidified oxygen

Correct answer: C

Rationale: The correct intervention for a client experiencing difficulty expectorating thick secretions due to pneumonia is to encourage increased fluid intake. Increasing fluid intake helps to thin secretions, making them easier to expectorate. Administering antibiotics (Choice A) is important in treating pneumonia but does not directly address the issue of thick secretions. Chest physiotherapy (Choice B) may help in some cases, but increasing fluid intake is a more straightforward and effective intervention. Providing humidified oxygen (Choice D) can help with oxygenation but does not directly address the problem of thick secretions.

5. The client is diagnosed with pneumonia. Which intervention is most effective in promoting airway clearance?

• A. Administer bronchodilators as prescribed
• B. Encourage increased fluid intake
• C. Perform chest physiotherapy
• D. Provide humidified oxygen

Correct answer: B

Rationale: Encouraging increased fluid intake is the most effective intervention in promoting airway clearance for a client with pneumonia. Increasing fluid intake helps to thin respiratory secretions, making it easier for the client to clear the airways. Administering bronchodilators may help with bronchospasm but does not directly promote airway clearance. Chest physiotherapy may be beneficial but is not the first-line intervention for promoting airway clearance in pneumonia. Providing humidified oxygen can improve oxygenation but does not directly address airway clearance.
