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.

Correct Answer: B

Rationale: Hydroxychloroquine can cause retinal toxicity, leading to vision loss. Regular ophthalmologic examinations are essential to detect early signs of toxicity. While dental, pulmonary, and endocrine health are important, they are not directly related to hydroxychloroquine's side effects. Monitoring for retinal changes is critical to ensure the safe use of this medication.

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.

Correct Answer: B

Rationale: ADHD in girls often presents as anxiety/withdrawal, versus boys' hyperactivity-per research-though diagnosis favors boys. It's not bipolar-mania/depression differ. Boys dominate diagnosis stats. It's early, not late, onset. Gender presentation accuracy reflects ADHD nuance.

Correct Answer: D

Rationale: When teaching patients about taking beta2-blocking drugs for the treatment of angina, it is important to include information about monitoring for signs of heart failure. Weight gain can be an early sign of fluid retention, which can indicate heart failure. Instructing patients to alert their healthcare provider if they experience a weight gain of 2 lb or more in 24 hours or 5 lb or more in 1 week can help in early detection and management of potential heart failure. This is crucial for the safety and well-being of the patient.

Correct Answer: D

Rationale: Cocaine intoxication (agitation, tachycardia, fever) causes vasoconstriction , via sympathetic stimulation, raising BP and temperature. Hypercoagulability occurs but isn't primary. Hypocoagulability and hypothermia oppose effects. Vasodilation (E) is wrong. This drives his symptoms.

Correct Answer: C

Rationale: To calculate the amount of aspirin in milligrams in a 5-gram tablet, we first need to convert 5 grams to milligrams. Since 1 gram is equal to 1000 milligrams, then 5 grams is equal to 5000 milligrams.

Correct Answer: D

Rationale: Metformin is a medication commonly used to treat type 2 diabetes by helping to control high blood sugar levels. It works by decreasing the amount of sugar produced by the liver and increasing the body's response to insulin. By aiding in controlling blood glucose levels, metformin helps prevent complications of diabetes such as kidney damage, blindness, nerve problems, and loss of limbs. It does not lower blood pressure, diminish seizure activity, increase heart rate, or decrease gastrointestinal secretions.

Correct Answer: C

Rationale: Rivastigmine, an acetylcholinesterase inhibitor, treats Parkinson's disease dementia by enhancing cholinergic function, improving cognition. However, increased acetylcholine can exacerbate tremors, a core Parkinson's symptom, by disrupting dopamine-acetylcholine balance in the basal ganglia, requiring cautious use. Benztropine, an anticholinergic, reduces tremors, not causes them. Rotigotine, a dopamine agonist, improves motor symptoms. Dimethyl fumarate manages MS, not Parkinson's dementia, and lacks tremor association. Rivastigmine's benefit in dementia must be weighed against its potential to worsen tremors, making it the drug needing careful monitoring in this context.
