Nursing Elites

1. 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.

2. For a patient with a history of liver disease, which type of diet is most appropriate?

• A. High-protein
• B. High-carbohydrate
• C. Low-protein
• D. Low-fat

Correct answer: D

Rationale: For a patient with a history of liver disease, a low-fat diet is most appropriate. Liver disease can impair fat metabolism, leading to fat accumulation in the liver cells and worsening the condition. A low-fat diet helps reduce stress on the liver and manage symptoms associated with liver disease. High-protein diets may not be suitable for individuals with liver disease as they can increase the risk of hepatic encephalopathy. High-carbohydrate diets may lead to insulin resistance and fat accumulation in the liver. While protein restriction may be necessary in some cases, a balanced intake of high-quality protein is essential for maintaining muscle mass and overall health, making a low-protein diet not the most appropriate choice for all patients with liver disease.

3. 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: Norepinephrine is indeed secreted by the adrenal medulla, making choice C the correct answer. The adrenal medulla is part of the adrenal glands, located on top of the kidneys. Norepinephrine is involved in the body's 'fight or flight' response, helping to prepare the body to react to stress. Choices A, B, and D are incorrect as norepinephrine is not secreted by the pancreas, adrenal cortex, or the anterior pituitary gland.

4. Six hours after major abdominal surgery, a male client complains of severe abdominal pain; is pale and perspiring; has a thready, rapid pulse; and states he feels faint. The nurse checks the client’s medication administration record and determines that the client receives another injection of pain medication in an hour. What is the appropriate action by the nurse?

• A. Explain to the client that it is too early to have an injection for pain
• B. Call the practitioner, report the client’s symptoms, and obtain further orders
• C. Reposition the client for greater comfort and turn on the television as a distraction
• D. Prepare the injection and administer it to the client early because of the severe pain

Correct answer: B

Rationale: The correct action for the nurse to take in this situation is option B: Call the practitioner, report the client’s symptoms, and obtain further orders. The client is displaying symptoms that indicate potential complications, such as internal bleeding, which require immediate medical evaluation. Option A is incorrect because the client's condition suggests a more urgent need for assessment. Option C is inappropriate as it does not address the seriousness of the client's symptoms. Option D is dangerous and could exacerbate any underlying issue the client may be experiencing.

5. Which of the following describes a process of heat loss involving the transfer of heat from one surface to another?

• A. Radiation
• B. Conduction
• C. Convection
• D. Evaporation

Correct answer: B

Rationale: Conduction is the process of heat transfer that occurs between objects or substances that are in direct contact with each other. In this process, heat is transferred from a hotter surface to a cooler surface through direct contact. This type of heat transfer does not involve the movement of the substances themselves, only the transfer of thermal energy. Choice A, Radiation, is the transfer of heat in the form of electromagnetic waves and does not require a medium. Choice C, Convection, involves the transfer of heat through the movement of fluids (liquids or gases) due to density differences. Choice D, Evaporation, is a cooling process that involves the transformation of a liquid into a gas, absorbing heat in the process.
