“A nurse is obtaining a 2-hr postprandial blood glucose from a patient. Which of the following actions should the nurse take?”
“Hold the finger above the heart prior to puncture.”.
“Smear the blood onto the reagent strip.”.
“Puncture the finger while still damp with antiseptic solution.”.
“Select the lateral side of the finger for puncture.”.
The Correct Answer is D
Choice A rationale
Holding the finger above the heart prior to puncture does not affect the accuracy of a blood glucose test.
Choice B rationale
Smearing the blood onto the reagent strip can result in inaccurate readings.
Choice C rationale
Puncturing the finger while still damp with antiseptic solution can cause discomfort and potentially contaminate the sample.
Choice D rationale
Selecting the lateral side of the finger for puncture is recommended because it is less painful and has good blood flow.

Correct Answer is C
Explanation
Choice A rationale
A thick, white vaginal discharge is more commonly associated with a yeast infection, not trichomoniasis.
Choice B rationale
Vulva lesions are not a typical symptom of trichomoniasis. They can be associated with other conditions such as herpes.
Choice C rationale
Trichomoniasis is a sexually transmitted infection caused by a parasite. One of the common symptoms in women is a foul-smelling vaginal discharge, which can be clear, white, yellowish, or greenish.
Choice D rationale
While urinary frequency can occur with trichomoniasis, it is not as specific or common as malodorous discharge.
Correct Answer is B
Explanation
Choice A rationale
A WBC count of 11,000/mm is slightly above the normal range (5,000 to 10,000/mm), but it is not uncommon for the WBC count to increase during pregnancy due to physiological changes and increased stress on the body. However, a significantly elevated WBC count could indicate an infection or other medical condition, so it should be monitored closely.
Choice B rationale
A fasting blood glucose level of 180 mg/dL is significantly above the normal range (74 to 106 mg/dL), indicating hyperglycemia. This could be a sign of gestational diabetes, a condition that can develop during pregnancy and cause high blood sugar levels. Gestational diabetes can increase the risk of various pregnancy complications, including preeclampsia, premature birth, and having a baby with a high birth weight. Therefore, this finding should be reported to the provider immediately.
Choice C rationale
A hematocrit level of 37% is within the normal range (37% to 47%), so it would not typically be a cause for concern.
Choice D rationale
A creatinine level of 0.9 mg/dL is within the normal range (0.5 to 1 mg/dL), so it would not typically be a cause for concern.
