,1. A patient is being evaluated during a cardiovascular examination, and the
clinician identifies a diastolic murmur during auscultation. The clinician also needs
to document the intensity of the murmur using the standard grading system. Which
statement correctly describes the significance and grading of murmurs?
Correct Answer: All diastolic murmurs are pathological; Grade III is clearly
audible, and Grade IV is the first grade associated with a palpable thrill.
Diastolic murmurs are considered pathological and require further evaluation
because they generally indicate abnormal blood flow across a cardiac valve or
another structural cardiac abnormality. Murmur intensity is graded from I to VI, with
Grade I being barely audible and Grade II being clearly audible but soft. Grade III is
clearly audible without a palpable thrill, whereas Grade IV is the first grade in which a
palpable thrill can be detected. Grade V can be heard with only the edge of the
stethoscope touching the chest, while Grade VI can be heard with the entire
stethoscope slightly lifted from the chest.
2. A pregnant patient presents for a routine prenatal examination and is
approximately 12 weeks' gestation. The provider assesses the abdomen and
measures the uterine fundal height to evaluate fetal growth and gestational
progression. At approximately 12 weeks of gestation, where should the fundus
normally be located?
Correct Answer: At the level just above the symphysis pubis.
At approximately 12 weeks of gestation, the enlarging uterus has become large
enough to rise above the pelvic cavity and can be palpated just above the symphysis
pubis. Fundal-height assessment provides an additional method of monitoring
pregnancy progression. As pregnancy advances, the fundus progressively rises
toward the umbilicus. The expected location at 12 weeks is therefore just above the
symphysis pubis.
,3. A pregnant patient is being assessed for uterine growth during the second
trimester. At 16 weeks, the clinician palpates the abdomen to determine the
location of the uterine fundus, and later at 20 weeks, another measurement is
obtained. Which fundal-height findings are expected at these gestational ages?
Correct Answer: At 16 weeks, the fundus is between the symphysis pubis and
umbilicus, and at 20 weeks, the fundus is approximately at the level of the
umbilicus.
At approximately 16 weeks of gestation, the uterine fundus is expected to be located
between the symphysis pubis and the umbilicus. By approximately 20 weeks, the
fundus typically reaches the level of the umbilicus. After 20 weeks, fundal height in
centimeters generally corresponds approximately to the number of weeks of
gestation, with a variation of about 2 cm above or below being considered
acceptable. A measurement significantly greater or smaller than expected may
warrant further assessment, such as ultrasonography.
4. A 3-month-old infant with Down syndrome has been experiencing milk
intolerance, so the mother recently began giving the infant goat's milk. The infant
appears otherwise healthy, but the nurse notes pale conjunctivae and laboratory
results showing a low hematocrit. Which additional laboratory tests should the
clinician order to further evaluate the suspected nutritional deficiency?
Correct Answer: Iron studies, including serum iron and total iron-binding
capacity (TIBC).
Pallor and a low hematocrit in an infant receiving goat's milk raise concern for iron-
deficiency anemia. Iron studies can help determine whether inadequate iron stores
are contributing to the anemia. Serum iron assesses circulating iron, while TIBC
provides information about the blood's capacity to bind iron. These results together
help support the assessment of iron deficiency and guide appropriate treatment.
, 5. A patient has been taking Synthroid (levothyroxine) for approximately 3 months
for hypothyroidism. Follow-up laboratory testing shows that the TSH remains
elevated while the T4 level is within the normal range. What is the appropriate
medication-related intervention?
Correct Answer: Increase the Synthroid (levothyroxine) dose.
An elevated TSH after treatment with levothyroxine may indicate that the current
thyroid hormone replacement dose is insufficient to adequately suppress TSH. Even
when the T4 is within the normal range, persistent elevation of TSH can indicate
incomplete correction of hypothyroidism. The medication dose may therefore need
to be increased based on the patient's laboratory results and clinical status. Thyroid
function should then be reassessed after the dose adjustment.
6. A patient presents with signs and symptoms of progressive memory loss, and the
clinician wants to perform a brief standardized assessment of cognitive function.
The assessment should evaluate areas such as orientation, recall, attention, and
other aspects of mental functioning. Which assessment would be appropriate?
Correct Answer: The Mini-Mental State Examination (MMSE).
The Mini-Mental State Examination is a standardized screening tool used to assess
several areas of cognitive function. It evaluates orientation, registration, attention,
calculation, recall, language, and other cognitive abilities. It can help identify
cognitive impairment and provide a baseline for monitoring changes over time. The
MMSE is a screening instrument and does not by itself establish the underlying cause
of memory loss.
7. A 4-month-old infant is brought to the clinic because the parents have noticed
intermittent strabismus. The mother is concerned that the infant's eyes do not
always appear to align properly. The infant is otherwise developing normally and
has no other concerning findings. What should the clinician tell the mother?
