Nursing Elites

1. The best definition of communication is:

• A. the sending and receiving of messages.
• B. the effect of sending verbal messages.
• C. an ongoing, interactive form of transmitting transactions.
• D. the use of message variables to send information.

Correct answer: C

Rationale: Communication is defined as an ongoing, interactive form of transmitting transactions. It involves a dynamic process of sending (encoding) and receiving (decoding) messages while being influenced by the experiences and perceptions of both the sender and receiver. This process is interactive and occurs within an environment, shaping individuals' self-concept, identity, and relationships. The correct answer captures the complexity and interactive nature of communication. Choice A, 'the sending and receiving of messages,' is too simplistic and does not encompass the interactive nature of communication. Choice B, 'the effect of sending verbal messages,' focuses solely on verbal communication and overlooks non-verbal forms. Choice D, 'the use of message variables to send information,' emphasizes technical aspects rather than the interactive and transactional nature of communication.

2. An elderly client is diagnosed with ovarian cancer. She has surgery followed by chemotherapy with fluorouracil (Adrucil) IV. What should the nurse do if she notices crystals and cloudiness in the IV medication?

• A. Discard the solution and order a new bag
• B. Warm the solution
• C. Continue the infusion and document the finding
• D. Discontinue the medication

Correct answer: A

Rationale: Crystals in the solution are not normal and should not be administered to the client. Discarding the solution and ordering a new bag is the correct action to ensure the client's safety. Warming the solution, as suggested in answer B, will not resolve the issue of crystals and cloudiness, which could potentially harm the client. Continuing the infusion, as in answer C, could pose a risk to the client due to the presence of abnormal substances. Answer D, discontinuing the medication, would typically require a doctor's order and should be done after discarding the contaminated solution.

3. When planning care of a client who has been diagnosed with Amphetamine Abuse, the nurse should use the knowledge that:

• A. Amphetamines increase energy by increasing dopamine levels at neural synapses.
• B. Amphetamines have a low risk of tolerance or addiction.
• C. Amphetamines produce a 10-20-second rush followed by a 2-4-hour high.
• D. Addiction to barbiturates and amphetamines is rare because they have opposite effects.

Correct answer: A

Rationale: The correct answer is that amphetamines increase energy by increasing dopamine levels at neural synapses. Amphetamines cause the release of norepinephrine and dopamine from storage vesicles into the synapse, leading to increased stimulation. It is important to note that clear patterns of tolerance and withdrawal have not been described with amphetamines. Choice B is incorrect as prolonged or excessive use of amphetamines can lead to psychosis, indicating a potential for addiction. Choice C is incorrect as the duration of the effects of amphetamines is typically longer than 2-4 hours. Choice D is incorrect as addiction to amphetamines is not rare; in fact, drug cravings are common and can lead to relapse, indicating a significant risk of addiction.

4. Client self-determination is the primary focus of:

• A. malpractice insurance
• B. nursing's advocacy for clients
• C. confidentiality
• D. health care

Correct answer: B

Rationale: Client self-determination refers to the right of clients to make their own decisions about their health care. Nursing's advocacy for clients focuses on upholding this right by supporting and respecting the autonomy and self-determination of clients. This advocacy ensures that clients are empowered to participate in decision-making regarding their health. Confidentiality, while essential, is about maintaining the privacy of client information. Malpractice insurance is a protective measure for professionals in case of errors or negligence. Health care, though crucial for enabling client self-determination, is a broad term encompassing various services and not the primary focus when discussing the client's right to autonomy.

5. While the client is receiving total parenteral nutrition (TPN), which lab test should be evaluated?

• A. Hemoglobin
• B. Creatinine
• C. Blood glucose
• D. White blood cell count

Correct answer: C

Rationale: When a client is receiving total parenteral nutrition (TPN), monitoring blood glucose levels is crucial as TPN solutions contain high amounts of glucose. This monitoring helps prevent hyperglycemia or hypoglycemia. Evaluating hemoglobin (choice A) is not directly related to TPN administration. Creatinine (choice B) is more relevant for assessing kidney function. White blood cell count (choice D) is important for evaluating immune function and infection, but not specifically tied to TPN administration.
