Extract:
Question 1 of 5
The nurse is monitoring a client who has received antidysrhythmic therapy for the treatment of premature ventricular contractions (PVCs). Which observation in the PVCs would indicate to the nurse that this therapy is ineffective?
Correct Answer: A
Rationale: PVCs are considered dangerous when they are frequent (more than 6 per minute), occur in pairs or couplets, are multifocal (multiform), or fall on the T wave.
Question 2 of 5
Your client has an allergy to both penicillin and latex. Which of these pathophysiological facts should you apply when you are providing to this client?
Correct Answer: A
Rationale: A sensitizing dose of penicillin can lead to anaphylaxis , a life-threatening allergic reaction, which is critical to consider when caring for a client with a penicillin allergy. The prevalence of dual allergies (C,
D) is not accurate, and distributive shock is not specific to a second dose.
Question 3 of 5
A client with a history of heart failure is prescribed spironolactone (Aldactone). The nurse should monitor the client for which of the following electrolyte imbalances?
Correct Answer: A
Rationale: Spironolactone, a potassium-sparing diuretic, can cause hyperkalemia, requiring monitoring.
Question 4 of 5
For which of the following should the nurse be especially alert when caring for a term neonate, who weighed 10 lb at birth, 1 hour after a vaginal delivery?
Correct Answer: A
Rationale: The neonate would be considered large for gestational age (LG
A) because the neonate weighs more than 4,000 g (90th percentile). Hypoglycemia is a problem for the LGA neonate because glycogen stores are quickly used to maintain the weight. Other complications like hyperbilirubinemia may occur, but hypoglycemia is the priority concern within the first hour.
