Nursing Elites

1. A nurse has been ordered to administer Morphine to a patient. Which of the following effects is unrelated to Morphine's effects on the patient?

• A. Depressed function of the CNS
• B. Increased blood flow
• C. Decreased venous capacity
• D. Pain relief

Correct answer: C

Rationale: Morphine is a narcotic analgesic that acts centrally to relieve pain by binding to opioid receptors in the CNS, leading to the depressed function of the CNS. Morphine also causes peripheral vasodilation, which can lead to increased blood flow. However, morphine causes venous dilation and increased venous capacity rather than decreased venous capacity. Therefore, the effect of 'Decreased venous capacity' is unrelated to Morphine's effects. Pain relief is a well-known effect of Morphine, as it acts on the CNS to alter the perception of pain.

2. The client has jaundice, elevated liver enzymes, and an elevated serum bilirubin. What color urine does the nurse expect to find?

• A. Pink-tinged
• B. Straw-colored
• C. Clear
• D. Dark amber

Correct answer: D

Rationale: The correct answer is dark amber. In jaundice, the elevated bilirubin levels are excreted in the urine, giving it a dark amber color. Choices A, B, and C are incorrect because in jaundice, the urine typically appears dark amber due to the presence of elevated bilirubin, not pink-tinged, straw-colored, or clear.

3. Which behavior by a new nurse would indicate to the charge nurse that this nurse is following standard precautions?

• A. Wearing clean gloves while performing a heel stick on an infant
• B. Wearing the same gloves for assessments of clients in the same room
• C. Wearing sterile gloves when changing the urine bag and nasogastric canister of an infected client
• D. Donning a gown when responding to a request by the family to check the IV pump on a client with rotavirus

Correct answer: A

Rationale: The correct answer is wearing clean gloves while performing a heel stick on an infant. Standard precautions require the use of gloves when there is a risk of exposure to blood or body fluids. Clean gloves are suitable for this task as they provide adequate protection without being sterile. Choice B is incorrect because wearing the same gloves for different clients can lead to cross-contamination, violating standard precautions. Choice C is incorrect as sterile gloves are usually not required for changing a urine bag and nasogastric canister unless a specific aseptic technique is indicated; standard precautions do not demand sterile gloves for such tasks. Choice D is incorrect as donning a gown is not necessary for checking an IV pump unless there is a risk of exposure to bodily fluids that would necessitate full-body protection, which is not indicated in this scenario.

4. A client is having psychological counseling for problems communicating with his mother. Which model of stress is the most useful in reference to this stressor?

• A. Adaptation Model
• B. Stimulus-Based Model
• C. Transaction-Based Model
• D. Selye's Model of Stress

Correct answer: C

Rationale: The Transaction-Based Model, proposed by R.S. Lazarus, is the most relevant model of stress in the context of a client facing communication issues with his mother. This model takes into consideration individual differences and cognitive processes that occur between a stressor and the individual's response. It emphasizes the importance of how the individual perceives and interprets the stressor, incorporating mental and psychological components. In this scenario, the client's difficulties in communicating with his mother involve complex cognitive processes and individual perceptions, making the Transaction-Based Model the most suitable choice. The other options are not as relevant in this context: the Adaptation Model focuses on adjustment to stress over time, the Stimulus-Based Model emphasizes external factors as stressors, and Selye's Model of Stress mainly centers on the physiological response to stress.

5. Which physiologic mechanism best describes the function of the sodium-potassium pump?

• A. active transport
• B. diffusion
• C. filtration
• D. osmosis

Correct answer: A

Rationale: Active transport is the correct answer as it accurately describes the process involved in the sodium-potassium pump. The pump utilizes energy to move ions against their concentration gradient, maintaining cellular concentrations. Diffusion (choice B) is a passive process where substances move from an area of higher concentration to lower concentration. Filtration (choice C) involves the movement of solutes based on pressure gradients. Osmosis (choice D) is the movement of water across a semipermeable membrane.
