Question 1 of 5
All of the following are unpaired cartilage except.
Correct Answer: C
Rationale: The correct answer is C: Corniculate cartilage. Corniculate cartilage is a paired cartilage found in the larynx, specifically at the apex of the arytenoids. The other choices, such as cricoid cartilage, epiglottis, and thyroid cartilage, are all unpaired cartilages. Cricoid cartilage is a complete ring, the epiglottis is a leaf-shaped cartilage, and the thyroid cartilage is the largest cartilage in the larynx. Therefore, Corniculate cartilage is the only paired cartilage among the options provided.
Question 2 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 3 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 4 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.
Question 5 of 5
All of the following pairings are correct (assuming normal person at rest) EXCEPT
Correct Answer: B
Rationale: The correct answer is B: Alveolar ventilation = 7500 ml. Alveolar ventilation is the volume of fresh air that reaches the alveoli per minute. It is calculated by subtracting the dead space ventilation from the tidal volume and then multiplying by the respiratory rate. In a normal person at rest, the average alveolar ventilation is around 4200 ml/min, not 7500 ml/min. Therefore, choice B is incorrect. Choices A, C, and D are correct because tidal volume is typically around 500 ml, pulmonary blood flow is about 5000 ml/min, and functional residual capacity is the volume of gas in the lung after normal expiration.
