ATI Capstone Pharmacology Assessment 1

Correct Answer: A

Rationale: The correct answer is A: Anorexia and weakness. These symptoms are early indicators of potential digitalis toxicity. Anorexia refers to a loss of appetite, which can be a sign of toxicity, and weakness can indicate an issue with digoxin. Choices B, C, and D are incorrect. Hyperactivity and hunger, tachycardia and increased urination, as well as polyphagia and polydipsia are not typically associated with digitalis toxicity.

Correct Answer: B

Rationale: The correct answer is B: Hematocrit. An increase in hematocrit levels indicates the effectiveness of epoetin alfa in treating anemia. Hematocrit reflects the percentage of red blood cells in the blood, so an increase in hematocrit signifies an improvement in the patient's red blood cell count and oxygen-carrying capacity. Choices A, C, and D are incorrect because white blood cell count, platelet count, and red blood cell count do not directly reflect the therapeutic effects of epoetin alfa in treating anemia.

Correct Answer: D

Rationale: The correct answer is D, Loop diuretics. Loop diuretics can lead to hypokalemia, which increases the risk for digoxin toxicity. Loop diuretics cause potassium loss, and hypokalemia can potentiate the toxic effects of digoxin. Choices A, B, and C are incorrect because calcium channel blockers, potassium-sparing diuretics, and beta blockers do not directly increase the risk of digoxin toxicity.

Correct Answer: D

Rationale: The nurse should combine both orders of insulin in the same syringe. To prepare the correct dose, the nurse should withdraw the regular insulin first (14 units) and then the NPH insulin (28 units), totaling 42 units. This combination ensures the client receives the prescribed doses of both types of insulin. Choices A, B, and C are incorrect because the nurse needs to prepare and administer both types of insulin as prescribed, resulting in a total of 42 units in the syringe.

Correct Answer: A

Rationale: The correct answer is to apply warm compresses to the mouth. Stomatitis is an inflammation of the mucous lining in the mouth and can be a side effect of chemotherapy. Warm compresses can help soothe the affected area and promote healing. Choice B is incorrect because alcohol-based mouthwash can further irritate the mouth. Choice C is also a good intervention as increasing fluid intake can help keep the mouth moist and promote healing. However, the most direct intervention for soothing and healing the affected area is applying warm compresses. Choice D is incorrect because using a firm toothbrush can be too harsh and cause further irritation.
