Nursing Elites

1. Which type of cells secrete insulin?

• A. alpha cells
• B. beta cells
• C. CD4 cells
• D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

2. Which of the following lab values would indicate symptomatic AIDS in the medical chart? (T4 cell count per deciliter)

• A. Greater than 1000 cells per deciliter
• B. Less than 500 cells per deciliter
• C. Greater than 2000 cells per deciliter
• D. Less than 200 cells per deciliter

Correct answer: D

Rationale: A T4 cell count of less than 200 cells per deciliter indicates symptomatic AIDS. This severe depletion of T4 cells signifies advanced HIV infection and a significantly compromised immune system. Choices A, B, and C are incorrect because T4 cell counts above 2000, above 1000, or below 500 cells per deciliter, respectively, are not indicative of symptomatic AIDS.

3. The physician wants to know if a client is tolerating their total parenteral nutrition. Which of the following laboratory tests is likely to be ordered?

• A. triglyceride level
• B. liver function tests
• C. a glucose tolerance test
• D. a complete blood count

Correct answer: B

Rationale: The liver is crucial in processing nutrients and medications received through total parenteral nutrition. Liver function tests assess various enzymes produced by the liver, including prothrombin time/partial prothrombin time, serum glutamic oxaloacetic and pyruvic transaminases, gamma glutamyl transpeptidase, albumin, and alkaline phosphatase. Monitoring these enzymes can help determine if the liver is functioning properly to metabolize the nutrients from TPN. Triglyceride levels (Choice A) primarily evaluate the body's ability to clear fats, not specifically related to TPN tolerance. A glucose tolerance test (Choice C) is used to diagnose diabetes by measuring blood glucose levels after ingesting a glucose-rich solution, not directly related to TPN tolerance. A complete blood count (Choice D) assesses blood components such as red blood cells, white blood cells, and platelets but does not provide specific information about TPN tolerance.

4. Which client should be seen first by the Emergency Department nurse?

• A. A six-year-old with a femur fracture.
• B. A two-year-old with a fever of 102 degrees F.
• C. A three-year-old with wheezes in the right lower lobe.
• D. A two-year-old whose gastrostomy tube came out.

Correct answer: C

Rationale: The priority in the emergency department is to assess and manage clients based on the severity of their condition. In this scenario, the three-year-old with wheezes in the right lower lobe should be seen first because respiratory distress takes precedence over other conditions. Wheezing indicates potential airway compromise, which requires immediate attention to ensure adequate oxygenation. The other options are important but do not pose an immediate threat to the client's airway and breathing. A femur fracture, fever, or a dislodged gastrostomy tube can be addressed after ensuring the child with respiratory distress is stable.

5. What is a chemical reaction between drugs before their administration or absorption known as?

• A. a drug incompatibility
• B. a side effect
• C. an adverse event
• D. an allergic response

Correct answer: A

Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly happens when drug solutions are mixed before intravenous administration, but it can also occur with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses occur after the administration and absorption of drugs, not prior to it.
