Questions and Answers with Rationales:
The nurse is assessing a client at 20 weeks' gestation. Which
measurement should be compared with the client's current
weight to obtain the most accurate data about her weight gain
during pregnancy?
A.Usual prepregnant weight
B.Weight at the first prenatal visit
C.Weight during previous pregnancy
D.Recommended pattern of weight gain -Answer:-A
,Rationale:
Comparing the client's current weight with her prepregnant
weight (A) allows for the calculation of weight gain. By the time of
the first prenatal visit (B), she may have already gained weight.
(C) may not be relevant to weight gain with the current
pregnancy. (D) should be evaluated based on serial weights, not
just a single current weight.
When caring for an 80-year-old client with pneumonia, which
finding is of most concern to the nurse?
A.Decrease in level of consciousness
B.BUN level, 20 mg/dL; creatinine level, 1.0 mg/dL
C.Reports of a dry mouth and lips
D.Fine crackles auscultated in lung bases -Answer:-A
Rationale:
A decrease in level of consciousness is a sign of decreased
oxygenation and requires immediate intervention (A). The others
are expected findings (B, C, and D).
The nurse is caring for a client with respiratory distress whose
arterial blood gas (ABG) results are as follows: pH, 7.33; Pco2,50
,mm Hg; Po2, 70 mm Hg; HCO3, 26 mEq/L. How should the nurse
interpret these results?
A.Metabolic acidosis
B.Respiratory alkalosis
C.Metabolic alkalosis
D.Respiratory acidosis -Answer:-D
Rationale:
A pH <7.25 and Pco2 >45 mm Hg with a normal HCO3 indicates
respiratory acidosis (D). The others are incorrect analyses of the
ABGs (A, B, and C).
A 12-year-old boy complains to the nurse that he is "short" (4'5"
[53 inches]). His twin sister is 5 inches taller than he is (4'10" [58
inches]). Based on these findings, what conclusion should the
nurse reach?
A.The boy is not growing as normally expected.
B.The girl is experiencing a period of unexpected growth.
C.A normal growth spurt occurs in girls 1 to 2 years earlier than
boys.
D.Male-female twins are not identical; therefore, their growth
cannot be compared. -Answer:-C
, Rationale:
Girls experience a growth spurt at 9.5 to 14.5 years of age and
boys at 10.5 to 16 years of age (C). There are insufficient data to
support (A); growth trends must be assessed to reach such a
conclusion. (B) is not unexpected. The fact that the children are
twins has less to do with their growth than the fact that they are
male and female (D).
A couple expresses concern and fear prior to having an
amniocentesis to determine fetal lung maturity. To assist them in
coping with this situation, which intervention is best for the nurse
to implement?
A.Explain that harm to the fetus is highly unlikely.
B.Answer all their questions regarding the procedure.
C.Encourage them to verbalize their feelings.
D.Show them a video about the procedure. -Answer:-B
Rationale:
The nurse should allay their concerns by providing information
about the procedure and answering questions (B). This action
assists the couple in coping with the situation. (A) may offer false
reassurance. (C) alone does not resolve the couple's fears.
Although (D) may be helpful, it is a passive activity, and the
