Question 1 of 5
The client is receiving oxytocin (Pitocin) for induction of labor. Which assessment finding will most likely result in the nurse stopping the infusion?
Correct Answer: A
Rationale: Oxytocin induces labor by stimulating uterine contractions, but excessive use can cause hyperstimulation, leading to continuous, sustained contractions . This risks uterine rupture or fetal distress, necessitating immediate cessation of the infusion to protect mother and baby. Transition is a labor stage, not a reason to stop unless complications arise. Strong contractions are expected, and regular contractions every 2-3 minutes are normal for labor induction. The nurse stops the infusion for sustained contractions due to their potential for catastrophic outcomes, making choice A the most likely trigger based on oxytocin's safety profile.
Question 2 of 5
A liquid preparation of K penicillin V contains 125mg/5ml. If you want a patient to take 250mg. each dose, you would prescribe ___ per
Correct Answer: C
Rationale: To prescribe 250mg of K penicillin V, you would need to have 10ml of the liquid preparation (125mg/5ml x 10ml = 250mg). Since 1 teaspoon (tsp) is approximately equal to 5ml, you would need to prescribe 2 teaspoons of the liquid preparation for the patient to take 250mg per dose.
Question 3 of 5
What is the peak range of regular insulin?
Correct Answer: D
Rationale: The peak range of regular insulin typically occurs between 1 to 5 hours after administration. This means that regular insulin will reach its maximum effectiveness in lowering blood sugar levels during this time frame. Patients should be aware of this peak range to help manage their diabetes effectively and time their meals and activities accordingly.
Question 4 of 5
The nurse administers lorazepam (Ativan) to a client with anxiety. Which statement by the client indicates understanding of the medication?
Correct Answer: B
Rationale: Lorazepam, a benzodiazepine, reduces anxiety via GABA enhancement but potentiates CNS depression with alcohol, risking sedation or respiratory failure. Avoiding alcohol shows understanding of this danger, key for safety. Driving is unsafe due to drowsiness. It doesn't cure anxiety 'it's symptomatic relief. Extra doses risk dependence. Avoiding alcohol aligns with lorazepam's pharmacology, critical in anxiety management where misuse is common, making B the statement reflecting proper education.
Question 5 of 5
The nurse is reviewing discharge teaching for a patient who will be taking digoxin (Lanoxin) therapy. The nurse will teach the patient to avoid which foods when taking the digoxin?
Correct Answer: C
Rationale: Grapefruit juice can interfere with the effectiveness of digoxin by inhibiting the enzyme responsible for metabolizing the drug in the body. This interaction can lead to increased levels of digoxin in the bloodstream, potentially causing harmful effects such as toxicity. It is important for patients taking digoxin to avoid consuming grapefruit juice to ensure the medication works as intended.
