Which of the following laboratory test results would suggest to the nurse Len that a client has a corticotropin-secreting pituitary adenoma?

Correct Answer: C

Rationale: Rationale: 1. Corticotropin-secreting pituitary adenoma causes excess ACTH production. 2. High ACTH stimulates adrenal glands to produce high cortisol levels. 3. Therefore, high corticotropin (ACTH) and high cortisol levels indicate corticotropin-secreting pituitary adenoma. Summary of Other Choices: A: High corticotropin and low cortisol levels suggest primary adrenal insufficiency (Addison's disease). B: Low corticotropin and high cortisol levels indicate adrenal tumor or exogenous steroid use. D: Low corticotropin and low cortisol levels indicate secondary adrenal insufficiency.

Correct Answer: B

Rationale: To calculate the amount of Digoxin to administer, we use the formula: Dose ordered (0.12 mg) / Dose on hand (0.05 mg) x Volume on hand (1 ml) = Volume to administer 0.12 / 0.05 x 1 = 2.4 ml Therefore, the nurse should administer 2.4 ml of Digoxin to the child. Choice B is correct because it accurately calculates the correct volume based on the dosage ordered and the concentration of the solution. Choice A, C, and D are incorrect as they do not calculate the correct volume based on the dosage and concentration provided in the question.

Correct Answer: C

Rationale: The correct answer is C: A Rh-negative. The rationale is that the client with AB negative blood type can receive blood from donors with blood type A or B, as well as Rh-negative blood to avoid any immune reactions. Choice A is incorrect because it is Rh-positive, which can lead to a hemolytic reaction. Choice B is incorrect because it is Rh-positive, which is not compatible with AB negative blood type. Choice D is incorrect because it is O, which is not compatible with AB blood type. Therefore, choice C is the safest option for the client to receive a blood transfusion without any adverse reactions.

Correct Answer: B

Rationale: The correct answer is B: Pulmonary embolism. Norma's symptoms of chest tightness, shortness of breath, tachypnea, and decreased consciousness are classic signs of a pulmonary embolism, which is a blockage in one of the pulmonary arteries in the lungs. These symptoms are due to a sudden obstruction of blood flow to the lungs, leading to impaired oxygen exchange and potentially life-threatening consequences. A: Asthma attack is incorrect because although asthma can present with chest tightness and shortness of breath, it typically does not cause a decreased level of consciousness. C: Respiratory failure is incorrect because it is a broad term that describes the inability of the respiratory system to adequately oxygenate the blood and remove carbon dioxide. It does not specifically point to the sudden onset of symptoms described in the scenario. D: Rheumatoid arthritis is incorrect because it is a chronic autoimmune disease that primarily affects the joints, and it does not present with the acute respiratory symptoms and decreased

Correct Answer: C

Rationale: The correct answer is C: Kidneys' excretion of sodium and water. When the kidneys excrete sodium and water, the blood volume decreases, leading to a drop in blood pressure. Excretion of excess sodium helps to reduce fluid retention, which can contribute to hypertension. Retention of sodium and water (B) would increase blood volume and blood pressure. Excretion of sodium only (A) would not address the issue of fluid retention. Retention of sodium and excretion of water (D) would not effectively reduce blood volume and lower blood pressure.
