Which technique should the nurse use to determine the presence of crepitus during a physical examination?

Correct Answer: A

Rationale: The correct technique to determine the presence of crepitus during a physical examination is palpation. Crepitus is a crackling or grating sensation that is felt when there is air trapped in the subcutaneous tissue. Palpation involves using the hands to feel for abnormalities such as crepitus. Percussion involves tapping on the body to produce sounds that can help assess underlying structures, not to determine the presence of crepitus. Auscultation is listening to sounds within the body using a stethoscope, which is not relevant for detecting crepitus.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): Promoting activity is the most prioritized nursing intervention for a client with CHF. Activity helps improve cardiac function, decreases fluid accumulation, and enhances overall cardiovascular health. It also prevents complications like muscle weakness and deconditioning. It is crucial in managing CHF symptoms and improving the client's quality of life. Summary of Incorrect Choices: A: Administering diuretics helps in reducing fluid overload but does not address the underlying issue of improving cardiac function through physical activity. B: Limiting fluid intake is important, but promoting activity takes precedence as it directly impacts cardiac function and fluid accumulation. D: Maintaining fluid balance is necessary but is a broad concept that includes various interventions, with promoting activity being more focused and critical in CHF management.

Correct Answer: D

Rationale: The correct answer is D because crossing arms and legs can indicate defensiveness or discomfort, which may suggest the parent is uneasy discussing their son's treatment. This nonverbal cue could signal a need for empathy and sensitivity in communication. Choice A is incorrect as it overlooks the significance of body language. Choice B assumes comfort without considering the context. Choice C assumes tiredness without considering other possibilities. Understanding body language cues can help in building rapport and addressing concerns effectively.

Correct Answer: A

Rationale: The correct answer is A because avoiding environmental allergens and cold air can help prevent asthma attacks. This shows the patient understands the importance of managing triggers. Choice B is incorrect because over-the-counter medications may not be sufficient for asthma management. Choice C is incorrect because smoking can worsen asthma symptoms. Choice D is incorrect because using the inhaler only when feeling short of breath is not a proactive approach to managing asthma triggers.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. Oxygen administration is the first intervention for shock as it helps improve oxygenation to vital organs. Lack of oxygen can worsen shock. Administering IV fluids (choice B) could be the second step to improve perfusion. Monitoring respiratory rate (choice C) is important but not the first intervention. Administering pain medication (choice D) is not a priority in managing shock.

Correct Answer: A

Rationale: The correct answer is A: Perform a CT scan. This is the priority action because it helps determine if the stroke is ischemic or hemorrhagic, guiding treatment decisions. Monitoring blood pressure (B) is important but not the priority. Administering aspirin (C) can be considered after confirming the type of stroke. Administering thrombolytics (D) is indicated for ischemic stroke but should only be done after ruling out hemorrhagic stroke with a CT scan.

Correct Answer: C

Rationale: The correct answer is C: Neutropenia. Chemotherapy can suppress bone marrow function, leading to a decrease in neutrophils (a type of white blood cell), causing neutropenia. This increases the risk of infection. Monitoring for signs of infection is crucial in patients receiving chemotherapy to prevent serious complications. Anemia (A) is a common side effect of chemotherapy but is not directly related to infection risk. Hyperkalemia (B) and hypocalcemia (D) are less likely to be immediate complications of chemotherapy compared to neutropenia.

Correct Answer: C

Rationale: The correct answer is C: Shortness of breath and chest pain. This is most concerning because it could indicate a pulmonary embolism, a serious complication of DVT where a blood clot travels to the lungs. Shortness of breath and chest pain are signs of compromised respiratory and cardiac function. A: Pain and swelling in the leg are common symptoms of DVT but not as concerning as symptoms of a pulmonary embolism. B: Redness and warmth around the affected area are typical signs of inflammation associated with DVT but do not indicate a life-threatening complication like a pulmonary embolism. D: Pale skin and decreased pulse in the affected leg could be signs of compromised circulation due to DVT, but they are not as immediately life-threatening as symptoms of a pulmonary embolism.

Correct Answer: A

Rationale: The priority nursing intervention for a client with asthma experiencing wheezing is to administer oxygen. Wheezing indicates airway constriction and decreased oxygenation, making oxygen crucial for adequate tissue perfusion. Administering oxygen helps improve oxygen levels, alleviate respiratory distress, and prevent hypoxemia. Applying a bronchodilator (Choice B) may be beneficial after oxygen is administered. Applying a cold compress (Choice C) is not indicated for asthma exacerbations, and encouraging deep breathing (Choice D) may worsen respiratory distress in a client with wheezing. In summary, administering oxygen is the priority intervention to address the immediate respiratory needs of the client with asthma and wheezing.
