Question 1 of 5
Which of the following changes does not occur at birth when an infant takes his or her first breaths?
Correct Answer: A
Rationale: The correct answer is A because at birth, when an infant takes their first breaths, blood flow to the lungs increases due to the expansion of the pulmonary vasculature. This allows for proper oxygenation of the blood. Choice B is incorrect as the resistance in the pulmonary arteries decreases to accommodate the increased blood flow to the lungs. Choice C is incorrect as changes in blood flow do cause the foramen ovale to close, ensuring proper circulation. Choice D is incorrect as air entering the alveoli is essential for oxygen exchange to occur in the lungs.
Question 2 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 3 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 4 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 5 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.
