Question 1 of 5
A client is prescribed total parenteral nutrition (TPN). Which education should the nurse provide?
Correct Answer: C
Rationale: Total parenteral nutrition (TPN) for long-term use requires a central line because it delivers high-concentration nutrients directly into large veins, like the subclavian, to avoid peripheral vein damage and ensure effective nutrient distribution. Clients can manage TPN at home with proper training, debunking the idea they must stay hospitalized until it's discontinued. It's also administered continuously or cyclically via an infusion pump for precise control, not on a twice-weekly outpatient schedule, which aligns with parenteral nutrition's complexity. The pump ensures steady delivery, critical for metabolic stability, while TPN's comprehensive nutritional support meets all dietary needs intravenously. This central line approach is standard for prolonged therapy, distinguishing it from short-term peripheral options, and supports home management, enhancing quality of life while addressing nutritional deficits effectively.
Question 2 of 5
The nurse provides care for elders in an assisted living facility. What does the nurse assess as a primary contributing factor for drug toxicity in the elderly?
Correct Answer: B
Rationale: Dehydration, common in elders from reduced thirst, lowers drug clearance (e.g., renal function drops), risking toxicity-key in pharmacokinetics. Alcohol abuse varies, not primary. Constipation affects excretion less than fluid status. Stomach acid decreases, not increases, with age. Dehydration's impact on volume and clearance drives toxicity risk.

Question 4 of 5
A 32-year-old anesthesiology resident injects himself with ketamine after he is served with divorce papers from his wife. In addition to being suspended from his hospital because of his actions, he would likely exhibit which of the following behaviors?
Correct Answer: D
Rationale: Ketamine, an NMDA antagonist, causes dissociative anesthesia. Slurred speech is correct-users often exhibit altered speech, disorientation, and motor impairment. Hypersensitivity to pain contradicts ketamine's analgesia. Loss of consciousness occurs at high doses, but self-injection suggests sub-anesthetic use. Normal gait is unlikely due to ataxia. Tranquil affect (E) doesn't fit agitation or dissociation. Slurred speech reflects ketamine's CNS depression, consistent with abuse scenarios.
Question 5 of 5
A 39-year-old man with long-standing allergies has no health insurance and simply takes over-the-counter diphenhydramine for symptom relief. He has no other medical problems but uses this medication up to four times per day. Which of the following effects of this medication is possible to be experienced by this patient?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
