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 pregnant woman who is having labor pains is receiving an opioid analgesic. Which of the following medications should be ready in case a respiratory depression occurs?
Correct Answer: B
Rationale: Naloxone (Narcan) is the antidote for opioid-induced respiratory depression and should be readily available when administering opioid analgesics during labor. It works by reversing the effects of opioids on the respiratory system, restoring normal breathing. Oxycodone, meperidine, and morphine are opioids and would exacerbate respiratory depression. Therefore, naloxone is the correct medication to have on hand.
Question 3 of 5
Which of the following is suitable for immediate treatment of an 18-year-old woman presenting with weight loss, tachycardia and a goitre?
Correct Answer: D
Rationale: Weight loss, tachycardia, and goitre suggest hyperthyroidism (e.g., Graves'). Verapamil controls rate but not thyroid function. Radioactive iodine (131I) treats long-term, not immediately. Carbamazepine is for seizures, L-thyroxine worsens hyperthyroidism. Atenolol, a beta-blocker, immediately reduces tachycardia and symptoms by blocking adrenergic effects, suitable for acute management while awaiting antithyroid drugs (e.g., propylthiouracil). Its symptomatic relief is critical in hyperthyroid crises.
Question 4 of 5
Which statement is false:
Correct Answer: C
Rationale: Higher potency (lower dose for effect) can coexist with lower efficacy (max effect), true, as potency reflects affinity, not ceiling effect. Higher receptor affinity increases potency, true, per receptor theory. Lower potency doesn't mandate lower efficacy; a less potent drug can achieve the same max effect with more dose, making this false. Higher potency with equal efficacy is true (e.g., partial agonists). This pharmacodynamic distinction is vital for drug selection, where efficacy often trumps potency.
Question 5 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.
