Nursing Elites

1. The nurse is aware that norepinephrine is secreted by which endocrine gland?

• A. The pancreas
• B. The adrenal cortex
• C. The adrenal medulla
• D. The anterior pituitary gland

Correct answer: C

Rationale: The correct answer is C: The adrenal medulla. Norepinephrine is secreted by the adrenal medulla and is involved in the body's 'fight or flight' response. The pancreas (choice A) secretes insulin and glucagon, not norepinephrine. The adrenal cortex (choice B) secretes hormones like cortisol and aldosterone, but not norepinephrine. The anterior pituitary gland (choice D) secretes various hormones like growth hormone and thyroid-stimulating hormone, but not norepinephrine.

2. When assessing the integumentary system of a client with anorexia nervosa, which finding would support the diagnosis?

• A. Preoccupation with calories
• B. Thick body hair
• C. Sore tongue
• D. Dry, brittle hair

Correct answer: D

Rationale: The correct answer is D: Dry, brittle hair. Dry, brittle hair is a common sign of malnutrition, often seen in clients with anorexia nervosa. Preoccupation with calories (choice A) is more related to the psychological aspect of anorexia rather than a physical finding. Thick body hair (choice B) is not typically associated with anorexia nervosa. A sore tongue (choice C) can be seen in conditions like vitamin deficiencies or oral health issues but is not specific to anorexia nervosa.

3. The nurse is teaching a community class to people with Type 2 diabetes mellitus. Which explanation would explain the development of Type 2 diabetes?

• A. The islet cells in the pancreas stop producing insulin
• B. The client eats too many foods that are high in sugar
• C. The pituitary gland does not produce vasopressin
• D. The cells become resistant to the circulating insulin

Correct answer: D

Rationale: The correct answer is D. In Type 2 diabetes, the primary issue is insulin resistance, where cells do not respond effectively to insulin. Choice A is incorrect because in Type 1 diabetes, the islet cells in the pancreas stop producing insulin. Choice B is not directly related to the development of Type 2 diabetes but rather to its management. Choice C is incorrect as it refers to a dysfunction in vasopressin production, which is not related to Type 2 diabetes.

4. The nurse administers 2 units of salt-poor albumin to a client with portal hypertension and ascites. The nurse explains to the client that this is administered to:

• A. Provide nutrients
• B. Increase protein stores
• C. Elevate the circulating blood volume
• D. Divert blood flow away from the liver temporarily

Correct answer: C

Rationale: The correct answer is C: Elevate the circulating blood volume. Albumin increases the circulating blood volume, which helps to reduce ascites and improve hemodynamics in clients with portal hypertension. Choice A is incorrect because salt-poor albumin is not primarily administered to provide nutrients. Choice B is incorrect because the main purpose of administering albumin is not to increase protein stores but to address fluid shifts. Choice D is incorrect because administering albumin does not divert blood flow away from the liver temporarily; instead, it helps improve blood volume and circulation.

5. A patient with chronic renal failure should avoid which of the following?

• A. Potassium
• B. Calcium
• C. Iron
• D. Zinc

Correct answer: A

Rationale: Patients with chronic renal failure should avoid potassium due to impaired kidney function. The kidneys may not effectively filter excess potassium from the blood, leading to hyperkalemia. Calcium, iron, and zinc do not need to be avoided specifically in chronic renal failure unless there are other underlying reasons or complications.
