Question 1 of 5
Which diagnostic test is commonly used to assess heart function in heart failure?
Correct Answer: A
Rationale: The correct answer is A: Electrocardiogram (ECG or EKG). An ECG is commonly used to assess heart function in heart failure because it provides information on the heart's electrical activity, rhythm, and any abnormalities. It can detect conditions such as arrhythmias, ischemia, and previous heart attacks. Other choices are incorrect: B (MRI) is more for imaging the structure of the heart, C (Colonoscopy) is for examining the colon, and D (Blood glucose test) is for measuring blood sugar levels, not heart function.
Question 2 of 5
Phrenic nerve are
Correct Answer: C
Rationale: The phrenic nerve innervates the diaphragm and arises from cervical nerve roots C3 to C5. Choice C is correct as it accurately states that the phrenic nerve is located in the diaphragmatic area and originates from C3 to C5. Choice A is incorrect as it only mentions the diaphragmatic area without specifying the cervical levels. Choice B is incorrect as it only mentions the cervical levels without specifying the diaphragmatic area. Choice D is incorrect as the phrenic nerve does exist.
Question 3 of 5
The home health nurse is educating a 60-year-old patient with emphysema with a nutritional deficit. Which instructions should the nurse avoid including in the teaching plan to address this problem?
Correct Answer: D
Rationale: The correct answer is D because lying down after eating can increase the risk of acid reflux and heartburn in patients with emphysema. A: Rest before eating is important as it can reduce shortness of breath during meals. B: Avoiding gas-producing foods can help prevent bloating and discomfort. C: Eating four to six small meals instead of three large meals is beneficial for easier digestion and energy management. In summary, D is incorrect because it can worsen symptoms, while A, B, and C are all helpful strategies for managing nutritional deficits in patients with emphysema.
Question 4 of 5
The nurse is caring for a client who is one hour post cardiac catheterization. What task should the nurse delegate to a licensed practical/vocational nurse (LPN/VN)?
Correct Answer: C
Rationale: The correct answer is C: Give the scheduled lipid-lowering medication. LPN/VNs can administer medications, including lipid-lowering drugs, under the supervision of a registered nurse. Teaching (choice A) requires a higher level of critical thinking and education, which is typically done by an RN. Performing an initial assessment (choice B) requires advanced assessment skills that an LPN/VN may not have. Titration of medications (choice D) involves adjusting dosages based on specific parameters, which is beyond the scope of practice for an LPN/VN.
Question 5 of 5
A client with bronchitis is admitted to the hospital. What would the nurse expect the admitting assessment NOT to reveal?
Correct Answer: D
Rationale: The correct answer is D: Bradycardia. In bronchitis, the body typically responds to inflammation by increasing heart rate (tachycardia) to improve oxygen delivery. Bradycardia is not a common finding in bronchitis and would be unexpected. Choices A, B, and C are commonly associated with bronchitis due to the inflammation in the airways causing cough, production of bloody sputum, and chest pain. These symptoms are typical manifestations of bronchitis and would be expected in the admitting assessment.
