What is the most important action when caring for a client on intravenous heparin?

Correct Answer: A

Rationale: The correct answer is A: Monitor aPTT levels. This is crucial in intravenous heparin therapy to ensure the therapeutic range is maintained for anticoagulation without causing bleeding. Monitoring aPTT helps adjust heparin dosage to prevent clot formation or excessive bleeding. B: Monitoring for bleeding is important but not the most important action compared to monitoring aPTT levels for appropriate dosing. C: Checking platelet count is important for some anticoagulants like heparin, but aPTT monitoring is more directly related to heparin's anticoagulant effect. D: Administering a heparin antidote (protamine sulfate) is necessary in case of heparin overdose or in emergency situations but is not the primary action in routine care.

Correct Answer: D

Rationale: The correct answer is D: Administer diuretics. The priority for a nurse caring for a client with pneumonia is to maintain adequate oxygenation and prevent respiratory failure. Diuretics help reduce fluid overload in the lungs, improving gas exchange and oxygenation. Administering antibiotics (choice A) is important to treat the infection but not the top priority. Administering oxygen (choice B) is crucial for oxygenation, but diuretics take precedence to improve lung function. Administering corticosteroids (choice C) may be considered in certain cases to reduce inflammation, but it is not the primary priority.

Correct Answer: A

Rationale: The correct answer is A: Administer IV fluids. In the case of shock, the first priority is to restore circulating volume to improve tissue perfusion. IV fluids help increase blood volume and improve oxygen delivery to vital organs, addressing the underlying cause of shock. Choice B (Administer oxygen) can be important but is not the first priority. Choice C (Place the client in a supine position) may worsen certain types of shock. Choice D (Monitor blood pressure) is important but not the first action needed to address shock. Administering IV fluids promptly can stabilize the client's condition and prevent further deterioration.

Correct Answer: D

Rationale: The correct answer is D: Create home care safety. Nursing activities that promote health and prevent disease focus on educating individuals on maintaining their health and preventing diseases, rather than specifically creating home care safety. The other choices (A, B, C) are correct as they accurately reflect the goals of nursing activities - reducing disease risk, maintaining optimal functioning, and reinforcing good habits to promote overall health and well-being. Choice D is incorrect because while ensuring home care safety is important, it is not the primary focus of nursing activities aimed at health promotion and disease prevention.

Correct Answer: B

Rationale: The correct answer is B because moving the wheelchair close and pivoting on the unaffected extremity is the safest way to transfer a client with hemiparesis. This method minimizes strain on the affected side and reduces the risk of falls. First, ensure the wheelchair is positioned close to the bed. Then, assist the client to pivot by placing weight on the unaffected side and using proper body mechanics. This technique maintains stability and prevents injury. Choice A is incorrect because standing and walking the client to the wheelchair puts excessive strain on the affected side, increasing the risk of falls. Choice C is incorrect as pivoting on the affected extremity can lead to injury and instability. Choice D is incorrect as having the client stand and push to the wheelchair can be dangerous and may cause further harm.

Correct Answer: D

Rationale: A focused assessment is more in-depth on specific issues, providing detailed information on a particular problem or concern. This allows for targeted interventions and treatment strategies. In contrast, a comprehensive assessment covers the body head to toe and involves all body systems, which may not be necessary when focusing on a specific issue. Occurring only in the clinic is a limitation to choice B, as assessments can be conducted in various settings. Involving all body systems, as stated in choice C, is not the primary focus of a focused assessment.

Correct Answer: B

Rationale: The correct answer is B: Tenderness, warmth, and swelling at the site. Post-operative wound infection often presents with localized tenderness, warmth, and swelling due to inflammation and immune response. Redness, heat, and purulent drainage (choice A) can also indicate infection but are not specific to wound infections. Excessive swelling and redness (choice C) may be present in inflammatory responses but do not specifically point to an infection. Fever, chills, and nausea (choice D) can be systemic signs of infection but are not specific to wound infections. Tenderness, warmth, and swelling are more indicative of a localized wound infection.

Correct Answer: A

Rationale: The correct answer is A: coma. High ammonia levels can lead to hepatic encephalopathy, causing impaired brain function and potentially leading to coma. Edema (B) is typically associated with fluid retention, not high ammonia levels. Hypoxia (C) is a condition of low oxygen levels, not directly related to high ammonia levels. Polyuria (D) is excessive urination, which is not a common sign of high ammonia levels.

Correct Answer: A

Rationale: Step 1: Stop the transfusion - Febrile reaction can indicate a transfusion reaction, so stopping the transfusion is crucial. Step 2: Administer antipyretics - To reduce fever and prevent further complications. Step 3: Assess for other signs of transfusion reaction - Such as chills, rash, or hypotension. Summary: Option A is correct as it addresses the immediate need to stop the transfusion and manage the fever. Options B, C, and D do not prioritize stopping the transfusion, which is crucial in this scenario.
