The patient has elevated blood urea nitrogen (BUN) and serum creatinine levels with a normal BUN/creatinine ratio. These levels most likely indicate
- A. increased nitrogen intake.
- B. acute kidney injury, such as acute tubular necrosis (ATN).
- C. hypovolemia.
- D. fluid resuscitation.
Correct Answer: B
Rationale: The elevated BUN and creatinine levels with a normal BUN/creatinine ratio indicate impaired kidney function. This pattern is commonly seen in acute kidney injury, such as acute tubular necrosis (ATN). In ATN, there is damage to the renal tubules leading to decreased excretion of waste products, resulting in elevated BUN and creatinine levels. The normal BUN/creatinine ratio suggests that the impairment is due to renal tubular dysfunction rather than prerenal causes like hypovolemia or postrenal causes like urinary obstruction. Increased nitrogen intake would not produce this specific pattern of results. Fluid resuscitation would likely result in dilution of BUN and creatinine levels, leading to lower values.

A client with asthma receives a prescription for high blood pressure during a clinic visit. Which prescription should the nurse anticipate the client to receive that is least likely to exacerbate asthma?
- A. Carteolol (Ocupress)
- B. Propranolol hydrochloride (Inderal)
- C. Pindolol (Visken)
- D. Metoprolol tartrate (Lopressor)
Correct Answer: D
Rationale: The correct answer is D, Metoprolol tartrate (Lopressor). Metoprolol is a cardioselective beta-blocker that primarily targets beta-1 receptors in the heart, making it less likely to exacerbate asthma compared to non-selective beta-blockers like Propranolol (choice B) and Pindolol (choice C). Carteolol (choice A) is also a non-selective beta-blocker and can potentially worsen asthma symptoms. Metoprolol's selectivity for beta-1 receptors minimizes bronchoconstriction, making it the safest choice for a client with asthma and high blood pressure.
The nurse is caring for a terminally ill patient who has chosen palliative care. Which goal should the nurse prioritize when planning care?
- A. Cure the patient’s underlying disease.
- B. Manage the patient’s pain and symptoms.
- C. Prolong the patient’s life expectancy.
- D. Address the family’s concerns and questions.
Correct Answer: B
Rationale: The correct answer is B: Manage the patient's pain and symptoms. In palliative care, the primary goal is to provide comfort and improve quality of life for terminally ill patients. Managing pain and symptoms is crucial in achieving this goal. By addressing pain and symptoms, the nurse can help enhance the patient's comfort and well-being. Other choices are incorrect because palliative care focuses on improving quality of life rather than curing the underlying disease (A), prolonging life expectancy (C), or primarily addressing family concerns (D). Prioritizing pain and symptom management aligns with the holistic approach of palliative care.
Upon entering the room of a patient with a right radial arte rial line, the nurse assesses the waveform to be slightly dampened and notices blood to bea bbirabc.ckoemd/te ustp into the pressure tubing. What is the best action by the nurse?
- A. Check the inflation volume of the flush system pressur e bag.
- B. Disconnect the flush system from the arterial line catheter.
- C. Zero reference the transducer system at the phlebostati c axis. WWWWWW ..TTHHEENNUURRSSIINNGGMMAASSTTEERRYY..CCOOMM
- D. Reduce the number of stopcocks in the flush system tubing.
Correct Answer: B
Rationale: The correct answer is B: Disconnect the flush system from the arterial line catheter. This action is necessary to prevent air from entering the patient's bloodstream, which can lead to air embolism. By disconnecting the flush system, the nurse stops the flow of air and ensures patient safety. Checking the inflation volume of the pressurized bag (A) is not the immediate concern in this situation. Zero referencing the transducer system (C) is unrelated to the issue of air entering the arterial line. Reducing the number of stopcocks in the flush system tubing (D) does not address the immediate risk of air embolism.
A client with cancer has a history of alcohol abuse and is taking acetaminophen (Tylenol) for pain. Which organ function is most important for the nurse to monitor?
- A. Cardiorespiratory.
- B. Liver.
- C. Sensory.
- D. Kidney.
Correct Answer: B
Rationale: The correct answer is B: Liver. The nurse should monitor liver function in this client because acetaminophen is primarily metabolized in the liver. Alcohol abuse can also contribute to liver damage, increasing the risk of liver toxicity from acetaminophen. Monitoring liver function tests like AST, ALT, and bilirubin levels can help detect any liver damage early.
Choice A, cardiorespiratory, is not directly related to acetaminophen or alcohol abuse in this scenario. Choice C, sensory, is not relevant to monitoring organ function in this context. Choice D, kidney, is not the primary concern because acetaminophen is mainly metabolized in the liver, and kidney function is not typically affected by acetaminophen use.
The patient’s partner, experiencing anticipatory grieving, tells the nurse, “I don’t see any point in continuing to visit at the bedside, since it’s like I’m not even here.” What is the nurse’s best response to the partner’s statement?
- A. “You’re right, there is no awareness of anything going on now.”
- B. “Unresponsiveness doesn’t mean the sense of hearing is gone and there is a benefit from you being present.”
- C. “I’ll call you if the patient begins responding again.”
- D. “Why don’t you check to see if any other family memb er would like to visit?”
Correct Answer: B
Rationale: The correct answer is B because it acknowledges the partner's feelings while providing information that may help them cope. By stating that unresponsiveness doesn't mean the patient can't hear, the nurse highlights the importance of the partner's presence for emotional support. It encourages the partner to continue visiting, emphasizing their role in providing comfort to the patient.
Choice A is incorrect as it dismisses the partner's feelings and lacks empathy. Choice C is incorrect as it implies the nurse will only involve the partner if the patient responds, neglecting the partner's emotional needs. Choice D is incorrect as it deflects responsibility from addressing the partner's concerns and suggests involving other family members without addressing the partner's feelings directly.
