1. The client is scheduled to undergo a treadmill stress test. Which instruction should the client be reinforced with?
- A. Eat a light meal before the test.
- B. Wear comfortable shoes and clothing.
- C. Avoid all physical activity the morning of the test.
- D. Take prescribed medications right before the test.
Correct answer: B
Rationale: The correct answer is B: 'Wear comfortable shoes and clothing.' Wearing comfortable shoes and clothing is crucial for the client undergoing a treadmill stress test to ensure they can complete the test without discomfort. The right attire will help the client move freely and reduce the risk of any hindrance during the test, which requires physical activity. Choices A, C, and D are incorrect. A light meal before the test may be recommended, but it's not as crucial as wearing suitable attire. Avoiding physical activity the morning of the test is not necessary as the test requires physical activity. Taking prescribed medications right before the test instructions should be followed as per the healthcare provider's advice and not as a general rule for all clients undergoing the test.
2. The client with a history of left-sided heart failure is exhibiting increasing shortness of breath and frothy sputum. What is the priority nursing action?
- A. Administer oxygen
- B. Encourage coughing and deep breathing
- C. Place the client in a supine position
- D. Notify the healthcare provider immediately
Correct answer: A
Rationale: Shortness of breath and frothy sputum are indicative of pulmonary edema, a serious condition that requires immediate intervention to improve oxygenation. Administering oxygen is the priority action to support the client's respiratory function and prevent further deterioration. Oxygen therapy helps increase the oxygen levels in the blood, alleviate respiratory distress, and support vital organ function. Prompt intervention with oxygen can help stabilize the client while further assessments and treatments are initiated. Encouraging coughing and deep breathing may worsen the client's condition by increasing respiratory effort. Placing the client in a supine position can further compromise breathing in a client with pulmonary edema. Notifying the healthcare provider is important but not the priority when the client's respiratory status is deteriorating.
3. A client is admitted to the emergency department with a suspected myocardial infarction (MI). The nurse should prepare the client for which immediate diagnostic test?
- A. Chest x-ray
- B. Electrocardiogram (ECG)
- C. Echocardiogram
- D. Coronary angiography
Correct answer: B
Rationale: An Electrocardiogram (ECG) is the most immediate and essential test to diagnose a myocardial infarction (MI) and assess the extent of heart damage. An ECG can quickly identify changes in the heart's electrical activity, allowing prompt initiation of appropriate interventions. A chest x-ray (Choice A) may show other conditions affecting the heart, but it is not the immediate test of choice for diagnosing an MI. An echocardiogram (Choice C) and coronary angiography (Choice D) are valuable in further assessing cardiac function and anatomy post-MI but are not the first-line diagnostic tests due to their time-consuming nature compared to an ECG.
4. What should be the nurse's priority action when a client diagnosed with angina pectoris complains of chest pain while taking a brisk walk?
- A. Administer nitroglycerin
- B. Have the client sit down
- C. Obtain an electrocardiogram
- D. Apply oxygen
Correct answer: B
Rationale: The nurse's priority action when a client diagnosed with angina pectoris complains of chest pain while taking a brisk walk is to have the client sit down. Sitting down reduces the workload on the heart and may alleviate pain by improving oxygen supply. This action aims to reduce the strain on the heart and improve oxygen delivery to the myocardium, which can help relieve the symptoms of angina pectoris. Administering nitroglycerin could be the next step after having the client sit down if the pain persists. Obtaining an electrocardiogram and applying oxygen are not the immediate priority actions when dealing with angina pectoris symptoms.
5. A client has a new prescription for heparin. Which of the following laboratory results should be monitored to evaluate the effectiveness of the medication?
- A. Prothrombin time (PT)
- B. International normalized ratio (INR)
- C. Activated partial thromboplastin time (aPTT)
- D. Platelet count
Correct answer: C
Rationale: Activated partial thromboplastin time (aPTT) is the laboratory result that should be monitored to evaluate the effectiveness of heparin. Heparin works by prolonging the aPTT, and monitoring this parameter helps ensure the medication's effectiveness and safety in preventing clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor the effectiveness of warfarin, another anticoagulant. Platelet count is essential to assess platelet function and clotting disorders, but it is not specifically used to monitor heparin therapy.
