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. Who typically collects blood specimens?

• A. The nurse
• B. Medical technologist
• C. Physician
• D. Phlebotomist

Correct answer: A

Rationale: Nurses typically collect blood specimens from patients as part of their everyday duties in medical settings. They are trained in venipuncture techniques and are responsible for ensuring that blood samples are properly obtained and labeled for diagnostic testing. Medical technologists process and analyze the blood specimens in the laboratory under the direction of a physician. Physicians are not commonly involved in the direct collection of blood specimens. While phlebotomists are specialized professionals trained to draw blood, in many medical settings, nurses perform this task as part of their responsibilities.

3. One of the reasons hospital patients are at greater risk for drug-nutrient interactions than they used to be is because:

• A. Hospitalized patients are more acutely ill
• B. Hospital routines interfere with the correct timing of medications
• C. Drugs used today are more toxic and have more side effects
• D. Responsibility for monitoring this is shared by various members of the healthcare team

Correct answer: A

Rationale: The correct answer is A. Hospitalized patients are more acutely ill, often having multiple conditions and treatments, which increases the risk of drug-nutrient interactions. Choice B is incorrect because hospital routines do not specifically interfere with the timing of medications in relation to drug-nutrient interactions. Choice C is incorrect because the toxicity and side effects of drugs do not directly relate to an increased risk of drug-nutrient interactions. Choice D is incorrect as sharing responsibility for monitoring does not inherently increase the risk of drug-nutrient interactions in hospital patients.

4. Warfarin (Coumadin) is an anticoagulant and interferes with the action of:

• A. Platelets
• B. Vitamin K
• C. Calcium
• D. Vitamin B12

Correct answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin inhibits the action of vitamin K, which is essential for blood clotting. By interfering with the production of certain clotting factors, warfarin helps prevent blood clots. Choices A, C, and D are incorrect because warfarin primarily affects the vitamin K-dependent clotting factors and not platelets, calcium, or vitamin B12.

5. A patient is prescribed an oral anticoagulant. What should the nurse monitor for?

• A. Elevated blood glucose
• B. Decreased blood pressure
• C. Signs of bleeding
• D. Increased appetite

Correct answer: C

Rationale: Correct! When a patient is prescribed an oral anticoagulant, the nurse should monitor for signs of bleeding. Oral anticoagulants are medications that prevent blood clot formation but can increase the risk of bleeding. Monitoring for signs such as easy bruising, blood in urine or stool, and prolonged bleeding from minor cuts is essential. Choices A, B, and D are incorrect because oral anticoagulants do not typically affect blood glucose levels, blood pressure, or appetite.
