A client with a history of closed head injury has a radial artery catheter in place and complains of numbness and pain distal to the insertion site. What action should the nurse take?

Correct Answer: B

Rationale: A weak pulse and numbness distal to a radial artery catheter may indicate occlusion or damage to the artery, and immediate removal of the catheter is necessary to prevent complications. Therefore, promptly removing the catheter from the radial artery (Choice B) is the correct action. Monitoring the site (Choice A) would delay necessary intervention, elevating the client's arm (Choice C) may not address the underlying issue, and notifying the healthcare provider for surgery (Choice D) without removing the catheter promptly could lead to further complications.

Correct Answer: B

Rationale: The most important dietary instruction for a client with renal disease is to limit fluid intake to 1500 ml/day. This is essential to prevent fluid overload, manage electrolyte balance, and reduce strain on the kidneys. Choice A is incorrect because while protein restriction may be necessary in some cases, avoiding all protein-rich foods is not recommended as some protein intake is essential for overall health. Choice C is incorrect because increasing potassium intake is generally not advised for clients with renal disease, as they often need to limit potassium intake. Choice D is also incorrect because while consuming small, frequent meals may be helpful, emphasizing a diet high in carbohydrates is not typically the primary focus for clients with renal disease.

Correct Answer: C

Rationale: The correct answer is C: Monitor the client's partial thromboplastin time (PTT). During heparin therapy for DVT, it is essential to monitor the PTT to assess the effectiveness of the medication in preventing clot formation. Monitoring the PTT helps ensure that the client is within the therapeutic range for anticoagulation. Choices A, B, and D are incorrect because liver function tests, prothrombin time (PT), and red blood cell count are not specifically monitored to assess the effectiveness of heparin therapy in preventing clot formation.

Correct Answer: C

Rationale: The best intervention for a client with dysphagia experiencing difficulty swallowing medications is to consult with the healthcare provider about switching to liquid medications. Liquid medications are often easier to swallow and can reduce the risk of choking and aspiration in clients with dysphagia. Crushing medications can alter their effectiveness, encouraging the client to drink water may not be sufficient, and offering soft foods is not directly related to improving medication swallowing.

Correct Answer: B

Rationale: Increased sensitivity to cold and dry skin may indicate that the dosage of levothyroxine is too low, requiring adjustment. This symptom is typical of hypothyroidism when the body's metabolism slows down, leading to feeling cold and having dry skin. Choices A, C, and D present symptoms more commonly associated with hyperthyroidism, where the body is in a state of overactivity, leading to weight loss, increased heart rate, and sweating. Therefore, these symptoms would not indicate the need for dosage adjustment in a client with hypothyroidism.
