NCLEX RN Predictor Exam - Nurselytic

Correct Answer: B

Rationale: The priority nursing action when a client reports symptoms like nausea and constipation is to complete an abdominal assessment. Assessment is crucial as it involves the systematic collection of data to understand the client's condition. By assessing the abdomen, the nurse can gather essential information to make a nursing diagnosis and develop a care plan. Collecting a stool sample (
Choice
A) may be necessary but comes after the assessment to confirm findings. Administering an anti-nausea medication (
Choice
C) addresses symptoms but does not address the underlying cause without a thorough assessment. Notifying the physician (
Choice
D) should come after the assessment to provide a complete picture of the client's condition.

Correct Answer: D

Rationale: The correct answer is 'One green, one red.' An H&H test involves hemoglobin and hematocrit, which are components of a complete blood count and are typically drawn in a lavender tube. On the other hand, blood for glucose testing is collected in grey tubes.
Therefore, when drawing blood for both an H&H and glucose test, one green tube for glucose and one red tube for H&H should be used. The other choices are incorrect because light blue tubes are used for coagulation studies, lavender tubes are for complete blood counts, and green tubes are for chemistry tests like glucose, while grey tubes are specifically for glucose testing.

Correct Answer: C

Rationale: The erythrocyte sedimentation rate (ESR) is a non-specific screening test for inflammation in the body. It is not used as a definitive diagnostic tool for specific conditions. When ESR results are abnormal, they indicate the presence of inflammation, which can be caused by various reasons.
Therefore, abnormal results should be followed by additional testing to determine the underlying cause. The ESR test measures the rate at which red blood cells settle in a vertical tube over the span of one hour, and results are reported in millimeters per hour.
Choice A is incorrect because ESR results are not solely diagnostic for any specific condition.
Choice B is incorrect as abnormal ESR results do not directly indicate a potentially fatal illness without further investigation.
Choice D is incorrect as the results are reported in millimeters per hour, not per minute.

Correct Answer: A

Rationale: A three-pronged plug functions as a ground to dissipate stray electrical currents. This helps prevent electrical shocks and ensures the safety of the user.
Choice B is incorrect because the number of prongs on a plug does not impact the efficient use of electricity.
Choice C is incorrect because a three-pronged plug does not shut off the appliance during an electrical surge; that role is typically fulfilled by surge protectors.
Choice D is incorrect as a three-pronged plug does not divide electricity among appliances in a room; it primarily serves as a safety measure to handle excess electrical currents.

Correct Answer: C

Rationale: When collecting blood from newborns, it is safest and most commonly done by collecting blood from the lateral or medial aspect of the baby's heel. This location is preferred due to the accessibility of the veins and the minimal discomfort caused to the newborn. Veins in the forehead are not commonly used for blood collection in newborns. The fingertips are not optimal for blood collection in newborns due to their small size and the potential for causing discomfort. The AC (antecubital) area, typically used in adults for blood collection, is not recommended for newborns due to the size of their veins and the potential risk of injury.
