Nursing Elites

1. A client with cancer is admitted to the oncology unit. Stat lab values reveal Hgb 12.6, WBC 6500, K+ 1.9, uric acid 7.0, Na+ 136, and platelets 178,000. The nurse evaluates that the client is experiencing which of the following?

• A. Hypernatremia
• B. Hypokalemia
• C. Myelosuppression
• D. Leukocytosis

Correct answer: B

Rationale: The correct answer is 'Hypokalemia.' The potassium level of 1.9 indicates low potassium levels, a condition known as hypokalemia. The other lab values are within normal ranges: Hgb 12.6, WBC 6500, uric acid 7.0, Na+ 136, and platelets 178,000. Hypernatremia (choice A) refers to high sodium levels, which are not present in this case. Myelosuppression (choice C) is a decrease in bone marrow activity, which is not indicated by the lab values provided. Leukocytosis (choice D) is an increase in white blood cells, which is also not present based on the given values.

2. 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.

3. A client sitting alone and talking to voices is observed by a nurse. When asked, the client reports he is 'talking to the voices.' The nurse's next action should be:

• A. touching the client to help him return to reality
• B. leaving the client alone until reality returns
• C. asking the client to describe what is happening
• D. telling the client there are no voices

Correct answer: C

Rationale: When a client reports talking to voices, it can indicate the presence of hallucinations. Asking the client to describe what is happening is a crucial step as it helps the nurse understand the nature of the hallucinations and provides reassurance to the client. Touching the client without consent is inappropriate and can be distressing. Leaving the client alone may not address the underlying issue, and telling the client there are no voices denies their experience and can lead to mistrust.

4. A client is taking hydrocodone (Vicodin) for chronic back pain. The client has required an increase in the dose and asks whether this means he is addicted to Vicodin. The nurse should base her reply on the knowledge that:

• A. the client's body has developed tolerance, requiring more drug to produce the same effect
• B. the client is preoccupied with getting the drug and is experiencing loss of control, indicating drug dependence
• C. addiction involves psychological behaviors related to substance use, not just physical dependence
• D. the client is coping with chronic back pain and requires adjustments in the medication regimen

Correct answer: A

Rationale: When a client requires an increased dose of a drug, such as in this case with hydrocodone, it suggests that the body has developed tolerance to the medication. Tolerance means that the client needs more of the drug to achieve the same effect as before. This does not inherently indicate addiction, which involves psychological behaviors related to substance use. Choice B describes drug dependence, where the client is preoccupied with obtaining the drug and experiences loss of control, which is not the same as tolerance. Choice C correctly points out that addiction is more than just physical dependence with withdrawal symptoms and tolerance; it includes psychological factors. Choice D is irrelevant as it discusses adjusting the medication for pain management, not addressing the client's concern about addiction.

5. 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.
