Question 1 of 5
Which is appropriate nursing care for a patient receiving total parenteral nutrition (TPN) in an acute care setting? (Select all that apply.)
Correct Answer: A
Rationale: Monitoring blood glucose (A) is critical because TPN can cause hyperglycemia. Measuring intake and output (B) helps assess fluid balance. Monitoring the insertion site (D) is essential to detect infection or infiltration. Blood should never be administered through the TPN line (C) due to risk of contamination.
Question 2 of 5
A 64-year-old alcoholic man who has not had access to alcohol for days is brought to the hospital by family. He is extremely agitated and reports seeing spiders on the walls that he wants to kill. His temperature is 39°C, pulse is 96 beats/minute, and blood pressure is 152/88 mm Hg. He is given a benzodiazepine, which mimics the effects of alcohol on his brain. Which of the following types of receptor to benzodiazepines is acted upon?
Correct Answer: D
Rationale: Alcohol withdrawal (hallucinations, agitation) is treated with benzodiazepines, acting on GABA-A ion channels . They enhance chloride influx, mimicking alcohol's calming effect. Options , , are fictional. Transcription factor (E) is unrelated. This mechanism stabilizes his withdrawal symptoms.
Question 3 of 5
The following decrease the rate of gastric emptying:
Correct Answer: D
Rationale: Amitriptyline, a tricyclic antidepressant, has anticholinergic effects that slow gastric motility, reducing the rate of gastric emptying.
Question 4 of 5
The student nurse asks the nursing instructor why he needs to take anatomy and physiology, as well as microbiology, when he only wants to learn about pharmacology. What is the best response by the instructor?
Correct Answer: C
Rationale: Anatomy, physiology, and microbiology underpin pharmacology, enabling nurses to grasp drug actions and patient responses, enhancing care through informed medication use. As an outgrowth oversimplifies their integration. Curriculum mandates explain requirements, not value. Understanding is key, but applying it to care-like knowing antibiotic targets or drug effects on organs-grounds pharmacology in practice, making it the best rationale.
Question 5 of 5
A patient suffering from generalized anxiety disorder (GAD) has a history of drug dependence that includes the illicit use of secobarbital ('reds') and a variety of other drugs. Psychotherapy is indicated, but the physician also prescribes a drug that can be helpful in GAD and that has the advantage of no abuse liability. The drug prescribed was most likely to have been
Correct Answer: B
Rationale: Buspirone, a 5HT1A partial agonist, treats GAD by modulating serotonin without sedative or euphoric effects, making it ideal for patients with substance abuse histories like secobarbital (a barbiturate). It lacks abuse potential, unlike benzodiazepines, and doesn't cause dependence, aligning with the patient's needs. Bupropion, an NE/DA reuptake inhibitor, targets depression and smoking cessation, not GAD, and has stimulant-like risks. Baclofen, a GABA_B agonist, manages spasticity, not anxiety, and has some abuse potential. Buprenorphine, an opioid partial agonist, treats addiction but not GAD and carries dependence risk. Phenobarbital, a barbiturate, mirrors the patient's abuse history and is contraindicated. Buspirone's efficacy in GAD, non-addictive nature, and safety in this context make it the optimal choice.
