RN exams clinical judgment practice questions set 146

Correct answer:

Correct Answer: B - Shallow breaths Rationale: 1. Abdominal or chest surgery can cause pain and restrict movement in the chest wall. 2. Pain and restricted movement may lead to shallow breathing. 3. Shallow breathing can result in decreased lung expansion and impaired gas exchange. 4. This can lead to complications such as atelectasis or pneumonia. Summary: A: Excessive coughing - While coughing may be painful post-surgery, it is not a direct risk associated with abdominal or chest surgery. C: Respiratory infection - While surgery can predispose patients to infections, shallow breaths directly impact respiratory function. D: Pneumonitis - While a potential complication, shallow breathing is a more immediate concern post-surgery for gas exchange.

Correct answer:

The correct answer is C: Ensuring proper endotracheal tube placement. This is the priority assessment because incorrect placement can lead to inadequate oxygenation and ventilation. Step 1: Verify tube placement by auscultating bilateral breath sounds. Step 2: Confirm placement with chest x-ray. Step 3: Assess for signs of respiratory distress to ensure adequate oxygenation. Choices A, B, and D are incorrect because they are important assessments but not the priority in this scenario. Checking for barotrauma (A) and monitoring for ventilator-associated pneumonia (B) are important considerations, but ensuring proper tube placement takes precedence. Assessing for sedation-related complications (D) is also crucial but not the priority assessment in this case.

Correct answer:

The correct answer is D: Home health agency nurse. The nurse includes the home health agency nurse in discharge planning as they will provide ongoing care and support for the neonate with a congenital breathing disorder at home. The home health agency nurse can assess the home environment, educate the family on care techniques, monitor the neonate's condition, and provide necessary interventions. A: Respiratory therapist may be involved in managing acute respiratory issues but may not provide ongoing care at home. B: Community agency manager may help with connecting to community resources but may not provide direct care. C: Social worker may assist with psychosocial support but may not have the expertise in managing the neonate's medical needs at home.

Correct answer:

The correct answer is D: The limbic system is largely responsible for one's emotional state. The limbic system, including structures like the amygdala and hippocampus, plays a crucial role in regulating emotions and emotional responses. The amygdala, for example, is involved in processing emotions such as fear and pleasure. Therefore, it is appropriate to inform the client that the limbic system controls emotions. Choice A is incorrect because the occipital lobe is primarily responsible for processing visual information. Choice B is incorrect as the parietal lobe is more associated with sensory processing and spatial orientation. Choice C is incorrect because the medulla is involved in regulating vital functions like breathing and heart rate, not emotions.

Correct answer:

The correct answer is B because Florence Nightingale demonstrated her role as an epidemiologist by showing that a safer environment led to decreased mortality rates. She implemented measures such as improving sanitation, ventilation, and hygiene in hospitals during the Crimean War, resulting in a significant reduction in deaths. This exemplifies her understanding of how environmental factors impact public health outcomes. Choice A is incorrect because convincing others to provide nursing care does not directly relate to epidemiology. Choice D is incorrect as addressing water, food supplies, lice, and rats pertains more to public health and sanitation practices rather than epidemiology. Choice C is left blank as it does not provide any relevant information.

Correct answer:

The priority action for the nurse is to determine the reasons why the client is refusing to use the incentive spirometer. By understanding the client's concerns or issues, the nurse can address them effectively, provide education or support, and encourage the client to comply with the necessary postoperative care. This approach fosters a patient-centered care environment. Demonstrating how to use the spirometer (Choice A) may be important but is not the priority at this moment. Setting a realistic postoperative goal (Choice B) is relevant but not as immediate as understanding the client's refusal. Requesting a respiratory therapist (Choice D) can be considered later if needed, but the nurse's initial focus should be on understanding the client's perspective.

Correct answer:

The correct answer is A because transient tachypnea of the neonate is primarily caused by the failure to clear lung fluid by the usual mechanism. During birth, the baby may not expel the lung fluid properly, leading to respiratory distress. This results in rapid breathing (tachypnea) due to the retained fluid in the lungs. The other choices are incorrect as they do not directly relate to the pathophysiology of transient tachypnea. Choice B involves the heart (patent ductus arteriosus), choice C relates to insufficient surfactant production seen in respiratory distress syndrome, and choice D mentions meconium aspiration syndrome, which is a different condition caused by the aspiration of meconium into the lungs, not related to the failure to clear lung fluid.

Correct answer:

The correct answer is B: Cool, clammy skin. Following a myocardial infarction, the client may experience hypotension due to decreased cardiac output. Cool, clammy skin indicates poor peripheral perfusion, a common manifestation of hypotension. This finding suggests inadequate blood flow to the skin. The other choices are incorrect because: A: A heart rate of 120 beats/min may indicate tachycardia, which is a compensatory mechanism to maintain cardiac output in response to hypotension. C: An oxygen saturation of 90% is below the normal range but is not a typical assessment finding related to hypotension after a myocardial infarction. D: A respiratory rate of 8 breaths/min is abnormally low but not directly related to hypotension post-myocardial infarction.

Correct answer:

The correct answer is C: A draining wound. Sterile dressings are necessary for draining wounds to prevent infection and promote proper healing. Draining wounds have an increased risk of contamination, making the use of sterile dressings essential. Choice A, a paper cut, typically does not require a sterile dressing as it is a minor wound. Choice B, an intact wound, does not require a sterile dressing unless there is a risk of infection. Choice D, a clean dry wound, also does not require a sterile dressing as long as it remains clean and dry. In summary, choice C is correct because draining wounds require sterile dressings to prevent infection, while the other choices do not necessarily require sterile dressings unless there are specific risk factors present.

Correct answer:

The correct answer is D: ultrafiltration. Ultrafiltration involves the removal of plasma water and low-molecular weight particles using a pressure or osmotic gradient. This process allows small molecules to pass through a semipermeable membrane while retaining larger molecules. Dialysis (A) involves the removal of waste products and excess fluids from the blood, while diffusion (B) is the movement of molecules from an area of high concentration to low concentration. Clearance (C) refers to the rate at which a substance is removed from the blood by a specific organ or process. Ultrafiltration specifically targets the removal of plasma water and low-molecular weight particles through a pressure or osmotic gradient, making it the correct choice in this context.
