Extract:
Question 1 of 5
To appropriately monitor therapy and client progress, the nurse should be aware that increased myocardial work and O2 demand will occur with which of the following?
Correct Answer: A
Rationale: Inotropic therapy will increase contractility, which will increase myocardial O2 demand. Decreased heart rate to the point of bradycardia will increase coronary artery filling time. This should be used cautiously because tachycardia may be a compensatory mechanism to increase cardiac output. The goal in the care of the MI client with angina is to maintain a balance between myocardial O2 supply and demand. Decrease in systemic vascular resistance by drug therapy, such as IV nitroglycerin or nitroprusside, or intra-aortic balloon pump therapy, would decrease myocardial work and O2 demand.
Question 2 of 5
A primigravida with diabetes is admitted to the labor and delivery unit at 34 weeks gestation. Which physician's order should the nurse question?
Correct Answer: B
Rationale: Terbutaline (Brethine) a tocolytic is used to stop preterm labor but is contraindicated in diabetic patients due to its risk of causing hyperglycemia. The other medications are appropriate for preeclampsia (magnesium sulfate) pain (butorphanol) or infection prophylaxis (cefazolin).
Question 3 of 5
Which food selection would provide the most calcium for a client who is four months pregnant?
Correct Answer: C
Rationale: Yogurt is a rich source of calcium essential for fetal bone development during pregnancy. One cup provides approximately 300-400 mg of calcium significantly more than oatmeal bran muffins or oranges.
Question 4 of 5
The physician has ordered an intravenous infusion of Pitocin for the induction of labor. When assessing the client’s response to the Pitocin, the nurse should give priority to:
Correct Answer: B
Rationale: Pitocin can cause uterine hyperstimulation, risking fetal distress. Checking the fetal heart rate is the priority to ensure fetal well-being. Blood pressure, contractions, and urinary output are monitored but are secondary to fetal status.
Question 5 of 5
A nurse is preparing to mix and administer chemotherapy. What equipment would be unnecessary to obtain?
Correct Answer: C
Rationale: Surgical gloves, Luer lok tubing, and long-sleeve gowns are essential for safe chemotherapy administration to prevent exposure. A surgical hat cover (
C) is not typically required unless in a sterile procedure.
