Question 1 of 5
Which of the following diseases or conditions is least likely to be associated with increased potential for bleeding?
Correct Answer: C
Rationale: Pernicious anemia results from vitamin B12 deficiency due to lack of intrinsic factor. This can result from inadequate dietary intake, faulty absorption from the GI tract due to a lack of secretion of intrinsic factor normally produced by gastric mucosal cells and certain disorders of the small intestine that impair absorption. The nurse should instruct the client in the need for lifelong replacement of vitamin B12, as well as the need for folic acid, rest, diet, and support.
Question 2 of 5
The client taking sertraline for treatment of depression for the past 11 months reports feeling much better and wishes to discontinue the medication. Which is the nurse's most appropriate response?
Correct Answer: A
Rationale: Sertraline (Zoloft) is an SSRI antidepressant. Stopping these abruptly can cause withdrawal symptoms. The dose should be reduced gradually.
Question 3 of 5
The newly hospitalized client admits using heroin 8 hours ago. Which assessment findings, if observed in the client, should the nurse associate with heroin withdrawal?
Correct Answer: B
Rationale: Dysphoric mood, pupillary dilation, and sweating are signs of heroin withdrawal. Heroin is an opioid.
Question 4 of 5
The client who is to receive a scheduled dose of digoxin has an irregular apical pulse at 92 bpm and a serum potassium of 3.9 mEq/L. Which nursing documentation reflects the most appropriate action?
Correct Answer: A
Rationale: A: A normal serum potassium level is 3.5 to 5.0 mEq/L. Digoxin (Lanoxin), a cardiac glycoside, slows and strengthens the heart. It is used for rate control in clients with atrial fibrillation, which often produces an irregular rhythm. B: Dysrhythmias can occur if digoxin is given when the serum potassium level is low, but the serum potassium level is WNL. Digoxin is used for rate control and would not be withheld due to an irregular HR. C: Although it is important to monitor for digoxin toxicity, the serum potassium level is WNL. D: Withholding digoxin and notifying the HCP are unnecessary; the serum potassium is WNL.
Question 5 of 5
A woman is in the active phase of labor. An external monitor has been applied, and a fetal heart deceleration of uniform shape is observed, beginning just as the contraction is under way and returning to the baseline at the end of the contraction. Which of the following nursing actions is most appropriate?
Correct Answer: D
Rationale: It is an early deceleration as a result of head compression, and at this time no action is necessary. Close observation of the mother and baby is needed.
