NCLEX RN Predictor Exam - Nurselytic

Correct Answer: D

Rationale: Bilirubin is easily broken down by light, so all samples testing positive for bilirubin should be protected from light exposure. Storing the specimen in an area protected from light helps maintain the integrity of the bilirubin levels for accurate testing.
Choice A is incorrect because the presence of bilirubin in urine does not necessarily indicate kidney disease.
Choice B is incorrect as the exposure to light, not room temperature, affects bilirubin levels.
Choice C is incorrect as the presence of bilirubin does not indicate the presence of bacteria in the specimen.

Correct Answer: A

Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine.
Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine.
Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester.
Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin).
Choice D is incorrect because not all the statements provided are true.

Correct Answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

Correct Answer: D

Rationale: When encountering an unfamiliar sound during auscultation, it is crucial for the nurse to seek confirmation from another healthcare professional. Asking the patient about their feelings may not provide insight into the unfamiliar sound. Simply documenting the findings without verification may lead to errors in interpretation. Waiting and auscultating again after 10 minutes might delay necessary intervention. Consulting another nurse for a second opinion ensures accurate identification of the unfamiliar sound and appropriate follow-up actions.
