Question 1 of 5
Nurse Sherry is teaching male client regarding his permanent artificial pacemaker. Which information given by the nurse shows her knowledge deficit about the artificial cardiac pacemaker?
Correct Answer: D
Rationale: The correct answer is D because engaging in contact sports is not recommended for individuals with a permanent artificial pacemaker, as it can increase the risk of damage to the device or harm to the individual. Taking the pulse rate daily, using electrical appliances, and having regular follow-up care are all appropriate and necessary for managing a permanent artificial pacemaker. It is important for the nurse to provide accurate information to ensure the client's safety and well-being.
Question 2 of 5
Nurse Kate is aware that one of the following classes of medication protect the ischemic myocardium by blocking catecholamines and sympathetic nerve stimulation is:
Correct Answer: A
Rationale: The correct answer is A: Beta-adrenergic blockers. These medications protect the ischemic myocardium by blocking catecholamines and sympathetic nerve stimulation, reducing the workload of the heart and oxygen demand. Beta blockers slow heart rate, decrease blood pressure, and improve coronary blood flow. Calcium channel blockers (B) primarily work by relaxing blood vessels and reducing the heart's workload. Narcotics (C) are pain-relieving medications and do not directly protect the ischemic myocardium. Nitrates (D) dilate blood vessels to improve blood flow but do not specifically block catecholamines and sympathetic nerve stimulation.
Question 3 of 5
Which of the following drugs would be ordered by the physician to improve the platelet count in a male client with idiopathic thrombocytopenic purpura (ITP)?
Correct Answer: B
Rationale: The correct answer is B: Corticosteroids. Corticosteroids are commonly prescribed to increase platelet count in ITP by suppressing the immune system's attack on platelets. ASA (choice A) can actually worsen bleeding in ITP. Methotrexate (choice C) is used for other autoimmune conditions, not ITP. Vitamin K (choice D) is not effective in treating ITP as it is involved in the clotting process, not platelet production.
Question 4 of 5
Nurse Sugar is assessing a client with Cushing's syndrome. Which observation should the nurse report to the physician immediately?
Correct Answer: B
Rationale: The correct answer is B: An irregular apical pulse. In Cushing's syndrome, excess cortisol can lead to cardiac arrhythmias. An irregular apical pulse indicates potential cardiac issues requiring immediate attention. Pitting edema (A) is common in conditions like heart failure. Dry mucous membranes (C) can be due to dehydration. Frequent urination (D) can be caused by conditions like diabetes. However, an irregular pulse is the most urgent concern due to the risk of serious cardiac complications.
Question 5 of 5
Rico with diabetes mellitus must learn how to self-administer insulin. The physician has prescribed 10 U of U-100 regular insulin and 35 U of U-100 isophane insulin suspension (NPH) to be taken before breakfast. When teaching the client how to select and rotate insulin injection sites, the nurse should provide which instruction?
Correct Answer: B
Rationale: Step 1: Rotating injection sites helps prevent lipohypertrophy and ensures consistent insulin absorption. Step 2: Rotating within the same region allows for proper absorption without causing tissue damage. Step 3: Injecting into healthy tissue with large blood vessels can lead to erratic absorption. Step 4: Administering into areas of scar tissue or hypotrophy can alter insulin absorption. Step 5: Administering into sites above muscles before exercise can lead to rapid absorption and hypoglycemia.
