Why is the intravenous route potentially the most dangerous route of drug administration?
- A. IV infiltration may occur.
- B. it allows for rapid administration of a drug.
- C. rapid administration of a drug can lead to toxicity
- D. it is the most commonly used route in hospitals.
Correct Answer: C
Rationale: The correct answer is C: rapid administration of a drug can lead to toxicity. When a drug is administered intravenously, it has 100% bioavailability, entering the bloodstream immediately and increasing the risk of toxicity if not carefully monitored. While IV infiltration (choice A) can cause tissue damage, it is not typically life-threatening. Choice B is incorrect as the speed of administration is not the primary reason for the danger; it is the immediate and full dose reaching the bloodstream. Choice D is incorrect as the popularity of the route does not inherently make it more dangerous.

While admitting a client to an acute-care psychiatric unit, the nurse asks about substance abuse based on:
- A. psychiatric disorders' higher prevalence in addicted populations
- B. individuals with psychiatric disorders' increased susceptibility to substance abuse
- C. the importance of detecting and diagnosing substance disorders in acute-care psychiatric settings
- D. the significant impact of undetected substance problems on the treatment of psychiatric disorders
Correct Answer: B
Rationale: The correct answer is 'individuals with psychiatric disorders' increased susceptibility to substance abuse.' It is crucial to inquire about substance abuse during admission to an acute-care psychiatric unit because individuals with psychiatric disorders are more prone to experiencing substance abuse issues. Addressing substance abuse is vital for effective treatment and to prevent relapse in psychiatric disorders. Option A is incorrect as it focuses on the prevalence of psychiatric illness in addicted populations rather than the relationship between psychiatric disorders and substance abuse. Option C is incorrect as it exaggerates the ease of detecting and diagnosing substance disorders in acute-care psychiatric settings. Option D is incorrect as undetected substance problems can indeed significantly impact the treatment of psychiatric disorders, but the main reason for inquiring about substance abuse is the increased susceptibility of individuals with psychiatric disorders to such issues.
The nurse is caring for a dying client who has persistently requested that the nurse 'help her to die and be in peace.' According to the Code of Ethics for Nurses, the nurse should:
- A. Ask the client whether she has signed the advance directives document.
- B. Tell the client that he or she will ask another nurse to care for her.
- C. Instruct the client that only a physician can legally assist in suicide.
- D. Try to make the client as comfortable as possible, but refuse to assist in death.
Correct Answer: D
Rationale: The correct answer is to try to make the client as comfortable as possible but refuse to assist in death. According to the Code of Ethics for Nurses, nurses are committed to providing compassionate care, respecting the dignity and rights of the dying person. In this situation, it is important for the nurse to focus on providing comfort and support to the client while upholding ethical standards. Choice A is incorrect because discussing advance directives does not address the immediate request for assistance in dying. Choice B is incorrect as it does not address the ethical dilemma presented. Choice C is incorrect because instructing the client that only a physician can assist in suicide does not fully address the complexity of the situation or the nurse's role in providing end-of-life care.
A man expresses surprise that his wife has become very withdrawn during hospitalization for pneumonia. Which response helps the husband understand how some people cope with hospitalization?
- A. "Hospitalization might cause a crisis. Has your wife had to cope with problems before this?"?
- B. "Some people react that way. She will be more talkative when she feels better."?
- C. "Your wife might be feeling concern that she cannot fulfill her normal roles."?
- D. "This is typical behavior for someone who is as ill as your wife."?
Correct Answer: A
Rationale: The correct response acknowledges that hospitalization can lead to a crisis for both patients and their families. By asking if the wife has coped with problems before, it opens up a dialogue about her coping mechanisms and past experiences. This can help the husband understand his wife's current behavior better and provide valuable insights. Choices B, C, and D do not directly address the potential crisis that hospitalization can cause or inquire about the wife's coping strategies, making them less effective responses.
A 50-milliliter (ml) bolus of normal saline fluid is ordered by the physician. The physician wants it to infuse in 30 minutes. The nurse should set the pump rate at:
- A. 100 ml per hour for one hour.
- B. 60 ml per hour for one-half hour
- C. 120 ml per hour for one hour.
- D. 50 ml per hour for one hour.
Correct Answer: A
Rationale: To infuse a 50 ml bolus in 30 minutes, the rate should be calculated as follows: 50 ml / 30 min = 100 ml per hour. Therefore, the correct answer is to set the pump rate at 100 ml per hour for one hour. Choice A is the correct rate based on the calculation. Choices B, C, and D all provide incorrect rates that do not match the physician's order. Choice B would only deliver 30 ml in 30 minutes, not the ordered 50 ml. Choice C would deliver 120 ml in one hour, which is 20 ml more than ordered. Choice D would only provide 25 ml over 30 minutes, not the full 50 ml prescribed.
The physician has prescribed tranylcypromine sulfate (Parnate) 10mg bid. The nurse should teach the client to refrain from eating foods containing tyramine because it may cause:
- A. Hypertension
- B. Hyperthermia
- C. Melanoma
- D. Urinary retention
Correct Answer: A
Rationale: If the client eats foods high in tyramine, he might experience malignant hypertension. Tyramine is found in cheese, sour cream, Chianti wine, sherry, beer, pickled herring, liver, canned figs, raisins, bananas, avocados, chocolate, soy sauce, fava beans, and yeast. These episodes are treated with Regitine, an alpha-adrenergic blocking agent. Choices B, C, and D are unrelated to the question: Hyperthermia is excessive body temperature, melanoma is a type of skin cancer, and urinary retention is the inability to empty the bladder.
