A client is receiving furosemide (Lasix) to relieve edema. The nurse should monitor
the client for which response to the medication?
1
Retention of sodium ions
2
Negative nitrogen balance
Correct3
Excessive loss of potassium ions
4
Increase in the urine specific gravity
Furosemide is a potent diuretic used to provide rapid diuresis; it acts in the loop of Henle
and causes depletion of electrolytes, such as potassium and sodium. Furosemide inhibits the
reabsorption, not retention, of sodium. Furosemide does not affect protein metabolism. With
edema, the specific gravity of the fluid more likely will be low.
Test-Taking Tip: Pace yourself when taking practice quizzes. Because most nursing exams
have specified time limits, you should pace yourself during the practice testing period
accordingly. It is helpful to estimate the time that can be spent on each item and still
complete the examination in the allotted time. You can obtain this figure by dividing the
testing time by the number of items on the test. For example, a 1-hour (60-minute) testing
period with 50 items averages 1.2 minutes per question. The NCLEX exam is not a timed
test. Both the number of questions and the time to complete the test varies according to
each candidate's performance. However, if the test taker uses the maximum of 5 hours to
answer the maximum of 265 questions, each question equals 1.3 minutes.

Issue with this question?
,A routine urinalysis is prescribed for a client. What should the nurse do if the
specimen cannot be sent immediately to the laboratory?
, 1
Take no special action.
Correct2
Refrigerate the specimen.
3
Store it in the dirty utility room and send it later.
4
Discard the specimen and collect another specimen later.
Refrigeration retards the growth of bacteria and may preserve the specimen for several
hours. Growth of bacteria will alter the pH and the glucose and protein levels in the urine; it
must be refrigerated to retard growth. Discarding the specimen and collecting another
specimen later represents an unnecessary waste of time, effort, and money.
Test-Taking Tip: Being emotionally prepared for an examination is key to your success.
Proper use of this text over an extended period of time ensures your understanding of the
mechanics of the examination and increases your confidence about your nursing knowledge.
Your lifelong dream of becoming a nurse is now within your reach! You are excited, yet
anxious. This feeling is normal. A little anxiety can be good because it increases awareness
of reality; but excessive anxiety has the opposite effect, acting as a barrier and keeping you
from reaching your goal. Your attitude about yourself and your goals will help keep you
focused, adding to your strength and inner conviction to achieve success.
