Correct Answer: B

Rationale: In a client with heart failure, decreased pedal edema is a positive indicator of improved cardiac output and reduced fluid retention. Digoxin works by increasing the strength of the heart's contractions, leading to improved circulation and reduced symptoms of heart failure, such as edema. Monitoring for decreased pedal edema is essential to assess the effectiveness of digoxin therapy. Choices A, C, and D are incorrect because an increased heart rate, elevated blood pressure, and improved urine output are not specific indicators of digoxin's effectiveness in managing heart failure. Instead, the focus should be on improvements related to fluid retention and cardiac function, like decreased pedal edema.

Correct Answer: C

Rationale: A white blood cell count of 2,000/mm3 is low and indicates leukopenia, which increases the client's risk for infection. Hemoglobin level and platelet count are not directly indicative of infection risk. Serum creatinine level is related to kidney function, not infection risk.

Correct Answer: C

Rationale: Fludrocortisone, such as Florinef, is a mineralocorticoid that promotes sodium retention and potassium excretion, which can lead to hypernatremia. Therefore, the nurse should closely monitor for hypernatremia when a client with Addison's disease is being treated with fludrocortisone. Hyperkalemia (Choice A) is incorrect because fludrocortisone promotes potassium excretion, leading to hypokalemia rather than hyperkalemia. Hyponatremia (Choice B) is incorrect as fludrocortisone promotes sodium retention. Hypocalcemia (Choice D) is unrelated to the action of fludrocortisone.

Correct Answer: C

Rationale: To prevent tracheal tissue damage in a client with a tracheostomy, the nurse should use the minimal leak technique when inflating the cuff. This method helps avoid excessive pressure on the tracheal tissue, thereby reducing the risk of damage. Choice A is incorrect because securing the tracheostomy ties too tightly can cause pressure and tissue damage. Choice B is incorrect as changing the tracheostomy tube daily is not necessary unless there is a specific clinical indication. Choice D is incorrect as cleaning the stoma with hydrogen peroxide can irritate the skin and mucous membranes, potentially leading to damage.

Correct Answer: A

Rationale: Placing the client in High Fowler's position is beneficial for individuals with left-sided heart failure experiencing dyspnea and orthopnea. This position helps to reduce venous return, decrease preload, and enhance respiratory function, thereby relieving the symptoms mentioned. Choice B, the supine position, is not recommended as it may exacerbate dyspnea and orthopnea by increasing preload. Choice C, the Trendelenburg position, is incorrect as it involves the feet being positioned higher than the head, which is not suitable for heart failure patients. Choice D, the Sims' position, is a lateral position used for rectal examination and is not indicated for relieving dyspnea and orthopnea in heart failure.
