Which of the following signs indicates to the nurse that digoxin (Lanoxin) has been effective for a patient?

Correct Answer: C

Rationale: The correct answer is C: Urine output increases. This indicates digoxin's effectiveness as it improves cardiac output by enhancing contraction strength. Increased urine output signifies improved kidney perfusion due to enhanced cardiac function. Option A is incorrect as decreased urine output indicates poor kidney perfusion. Option B is incorrect as digoxin aims to regulate heart rate, not necessarily make it higher than 95. Option D is incorrect as a heart rate lower than 50 could indicate digoxin toxicity.

Correct Answer: A

Rationale: The correct answer is A: Postural hypotension. This condition is characterized by a drop in blood pressure upon standing, leading to dizziness. The client's symptoms of dizziness upon standing, along with nosebleeds and blurred vision, are indicative of low blood pressure. Postural hypertension (B) is not a recognized medical condition; White coat hypertension (C) refers to elevated blood pressure readings in a medical setting due to anxiety; White coat hypotension (D) is not a recognized medical condition.

Correct Answer: C

Rationale: The correct answer is C: To comply with the medication regimen. Teaching the older client with TIA to comply with medication regimen is crucial in preventing further TIAs or strokes. Medications like antiplatelets or anticoagulants are often prescribed to manage TIA. This education empowers the client to actively participate in their own health management. Incorrect choices: A: Not to worry about the symptoms that are part of the normal aging process - This is incorrect as TIA symptoms are not considered a normal part of aging and should not be ignored. B: To admit oneself to a rehabilitation center or a nursing home for rehabilitation - This is incorrect as it is not the primary intervention for managing TIA. D: To observe any changes in the nails and skin - This is incorrect as it is not directly related to managing TIA.

Correct Answer: C

Rationale: The correct answer is C: Bacon. Bacon contains the highest kilocalorie among the given choices due to its high fat content. Fat provides 9 kilocalories per gram, while carbohydrates (like in bread and apple) provide 4 kilocalories per gram and protein (like in chicken) provides 4 kilocalories per gram. Bacon, being high in fat, has more kilocalories compared to the other choices. Summary: A: Apple - Low in fat, primarily consists of carbohydrates, hence lower in kilocalories. B: Chicken - Contains protein, lower in kilocalories compared to fat, hence not the highest kilocalorie choice. D: Bread - Mainly consists of carbohydrates, lower in kilocalories compared to fat, making it not the highest kilocalorie choice.

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Potassium is typically administered on a secondary line to prevent rapid infusion and potential adverse effects. 2. The primary line carries the D5 ½ NS solution without potassium, while the secondary line delivers the potassium. 3. Reporting that "potassium is on the secondary line" accurately describes the setup for this IV infusion. Summary: A: Incorrect - Incorrectly states that the potassium bag is piggybacked into the dextrose. B: Incorrect - Closing the clamp below the D5 ½ NS bag is unnecessary and does not address the potassium infusion. D: Incorrect - Fails to address the specific issue of the potassium infusion being on a secondary line.
