What is the recommended dietary restriction for a patient with chronic kidney disease?

Correct Answer: B

Rationale: The correct answer is to limit fluid intake for a patient with chronic kidney disease. This restriction helps manage fluid balance to prevent fluid overload. Choices A, C, and D are incorrect. Limiting potassium intake is essential for some patients with kidney disease, but it is not the primary dietary restriction. Increasing protein intake is usually not recommended due to the impaired kidney function in these patients. Increasing carbohydrate intake is also not a standard recommendation for patients with chronic kidney disease.

Correct Answer: B

Rationale: When a patient presents with confusion, the best initial action is to perform a neurological assessment. This assessment helps in identifying potential causes of confusion such as neurological issues, infections, metabolic abnormalities, or medication side effects. Administering IV fluids (Choice A) may be necessary based on assessment findings, but it is not the first step. Administering electrolytes (Choice C) would also depend on the assessment results. Preparing for a CT scan (Choice D) may be indicated later in the diagnostic process but is not the initial action when a patient presents with confusion.

Correct Answer: A

Rationale: Methimazole is the correct answer. It is commonly used to treat hyperthyroidism by inhibiting the production of thyroid hormones. Levothyroxine, on the other hand, is a medication used to treat hypothyroidism by providing synthetic thyroid hormone. Propylthiouracil is another medication used to treat hyperthyroidism by blocking the production of thyroid hormones. Aspirin is not used to treat hyperthyroidism, but rather for pain relief and reducing inflammation.

Correct Answer: D

Rationale: Clients diagnosed with tuberculosis should be placed in a negative pressure room to prevent the spread of airborne pathogens. Option A is incorrect because administering isoniazid is a treatment for tuberculosis, not a preventive measure related to infection control. Option B is incorrect as droplet isolation is used for diseases transmitted through respiratory droplets, not airborne pathogens like tuberculosis. Option C is incorrect as wearing a surgical mask is not sufficient to prevent the spread of tuberculosis in healthcare settings; placing the client in a negative pressure room is the most effective measure.

Correct Answer: A

Rationale: Administering IV fluids is the best intervention for a patient with dehydration because it is the fastest and most effective way to rehydrate the body. IV fluids can quickly restore fluid volume and electrolyte balance in severe cases of dehydration. Providing oral fluids or encouraging fluid intake may not be sufficient for patients with moderate to severe dehydration, as they may have impaired gastrointestinal absorption. While electrolytes are essential for rehydration, administering them alone without fluid replacement may not address the primary issue of fluid loss in dehydration.

Correct Answer: A

Rationale: The correct answer is to monitor aPTT. Activated Partial Thromboplastin Time (aPTT) is crucial to monitor when a patient is receiving heparin therapy. Heparin works by potentiating antithrombin III, leading to the inhibition of thrombin and factor Xa. Monitoring aPTT helps ensure the patient is within the therapeutic range for heparin, reducing the risk of bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy. Monitoring potassium (Choice C) and sodium levels (Choice D) is important but not specific to heparin therapy.

Correct Answer: C

Rationale: The correct intervention for a client with Alzheimer's disease who demonstrates confusion and wandering behavior is to ensure that the client wears an identification bracelet at all times. This helps prevent wandering and ensures the client's safety. Placing the client in a well-lit area may be beneficial for orientation but does not directly address wandering behavior. Using physical restraints is not recommended as it can lead to agitation and other complications. Keeping the client's bed in the lowest position is important for fall prevention but does not specifically address the issue of wandering behavior.

Correct Answer: B

Rationale: The correct answer is B. An elevated creatinine level, such as 1.8, suggests potential kidney dysfunction, requiring further assessment. Sodium level within normal limits (135-145 mEq/L), hemoglobin level of 15 g/dL, and potassium level of 4.2 mEq/L are all within normal ranges and do not indicate immediate concerns. Therefore, they do not require further evaluation at this time.

Correct Answer: C

Rationale: The correct way to monitor a patient who has been prescribed digoxin is by checking digoxin levels. Digoxin is a medication used to treat various heart conditions, and monitoring its levels in the blood is crucial to prevent toxicity. Monitoring potassium levels (Choice A) is important as well, as digoxin can affect potassium levels, but checking digoxin levels is more specific to monitoring the medication itself. Monitoring heart rate (Choice B) is relevant but does not directly assess the medication levels. Checking blood glucose levels (Choice D) is not typically indicated specifically for patients prescribed digoxin.
